Internal Consistency (internal + consistency)
Kinds of Internal Consistency Terms modified by Internal Consistency Selected AbstractsEvaluation of the Mini-Mental State Examination's Internal Consistency in a Community-Based Sample of Mexican-American and European-American Elders: Results from the San Antonio Longitudinal Study of AgingJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2004David V. Espino MD This study examined the effect of scoring method, education, and language usage on internal consistency of the Folstein Mini-Mental State Examination (MMSE). Trained bilingual staff administered the MMSE in participants' homes as part of the San Antonio Longitudinal Study of Aging home-based assessment battery. Subjects included 833 community-dwelling Mexican-American (MA) and European-American (EA) elders, aged 65 and older, residing in three socioculturally distinct neighborhoods in San Antonio, Texas. Three methods of scoring the MMSE were examined: serial sevens only, spelling only, and serial sevens or spelling, whichever was higher. Mean MMSE scores±standard deviation ranged from 27.7±2.4 to 28.5±1.9 for EAs, from 25.6±3.2 to 27.2±2.9 for MAs interviewed in English, and from 22.5±4.5 to 25.5±3.5 for MAs interviewed in Spanish, depending on scoring method. Across the three ethnic-language subgroups, the lowest mean scores, largest coefficients of variation, and highest alpha coefficients were observed using serial sevens only. Stratification by educational level showed that alpha coefficients for all three scoring methods were consistently lower in high school graduates than in less-educated groups. Serial sevens only was the only scoring method that yielded acceptably high alpha coefficients across all ethnic, language, and education subgroups. Thus, clinicians should use the serial sevens,only method when administering the MMSE and be alert to the increased potential for false-negatives in more highly educated EA and MA elders, particularly in EAs and MAs proficient in English. [source] Cognitive variables and depressed mood in adults with intellectual disabilityJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 7 2005A. J. Esbensen Abstract Background Cognitive theory forms the foundation for cognitive therapy. There has been little research on cognitive theories and cognitive variables associated with depression in individuals with intellectual disability (ID). The current study examined cognitive variables of automatic thoughts, cognitive triad, hopelessness, attributions and self-esteem associated with two cognitive theories of depression: Beck's Cognitive Triad theory and the Hopelessness theory of depression. Methods Seventy-three adults with ID screened for adequate receptive vocabulary were interviewed as part of a larger study. They reported on cognitive constructs relating to depressed mood. In addition, comparisons were made between 12 adults with ID and diagnosed major depression and a matched group of 12 adults with ID and no psychiatric diagnoses in order to determine if these groups differed on the cognitive constructs associated with the two cognitive theories of depression. Results The cognitive variables examined were all significantly correlated with depressed mood in the direction predicted by their respective cognitive theory. Internal consistencies were good or excellent for most instruments, with the exception of those measuring hopelessness and attributions. In addition, significant differences were obtained between groups of individuals with and without co-morbid major depression on all variables except for hopelessness. Conclusions The results indicate that adults with ID screened for adequate receptive vocabulary are capable of reporting on subjective feelings of depressed mood and associated cognition constructs. The instruments used may be suitable for this population as they generally possessed sound internal consistencies. The results support the further examination of cognitive theories of depression among individuals with ID in order to assess the appropriateness of cognitive therapies for this population. Discrepant findings regarding hopelessness are discussed. [source] The development and standardization of the Children Activity Scales (ChAS-P/T) for the early identification of children with Developmental Coordination DisordersCHILD: CARE, HEALTH AND DEVELOPMENT, Issue 6 2006S. Rosenblum Abstract Background Previous studies have emphasized the importance of early identification of children with Developmental Coordination Disorder (DCD) to prevent the development of secondary academic, emotional and social manifestations of the disorder. The aim of this study was to develop a valid parent and teacher questionnaire , the Children Activity Scales for parents (ChAS-P) and for teachers (ChAS-T) , to identify children aged 4,8 years at risk for DCD and to examine the reliability and validity of these questionnaires. Methods The questionnaires' content and face validity were established, and then cut-off scores were determined based on responses of 355 teachers and 216 parents. Internal consistencies were also calculated. Factor analyses were performed, and construct validity was determined by examining the questionnaires' ability to discriminate between 30 children aged 5,6.5 years diagnosed with DCD and 30 typically developing children. Concurrent validity was examined by comparing questionnaire scores with those of the Movement Assessment Battery for Children (M-ABC). Results High values were obtained for internal consistency (0.96,0.94) for the ChAS-T and the ChAS-P respectively. Factor analysis revealed four distinct factors within the ChAS-P and three within the ChAS-T, reinforcing the theoretical validity of the items selected and appropriateness for identifying DCD. Construct validity was indicated by finding significant differences between the groups' scores on the ChAS-T and the ChAS-P. Significant correlations between the children's scores on the questionnaires and those of the M-ABC confirmed their concurrent validity. Conclusions Initial results suggest that the ChAS-T and Chas-P are reliable tools to identify children at risk for DCD. [source] Does subtle screening for substance abuse work?ADDICTION, Issue 1 2007A review of the Substance Abuse Subtle Screening Inventory (SASSI) ABSTRACT Aim Through a complex combination of direct (face-valid) and indirect (subtle) subscales, the Substance Abuse Subtle Screening Inventory (SASSI) is purported to detect substance use disorders with a high degree of validity regardless of respondent honesty or motivation. This review evaluates empirical evidence regarding the reliability and validity of this widely used screening instrument. Methods Source documents were 36 peer-reviewed reports yielding data regarding the SASSI's internal consistency, test,retest reliability, psychometric structure, convergent and divergent validity and criterion (predictive) validity. Results The total N of the studies reviewed equaled 22 110. Internal consistency is high for the overall SASSI and for its direct but not its indirect (subtle) subscales, suggesting that the instrument taps a single face-valid construct. SASSI classifications converged with those from other direct screening instruments, and were also correlated with ethnicity, general distress and social deviance. Studies found test,retest reliability lower than that reported in the test manuals. Sensitivity was found to be similar to that for public domain screening instruments, but on specificity the SASSI appears to yield a high rate of false positives. Conclusion No empirical evidence was found for the SASSI's claimed unique advantage in detecting substance use disorders through its indirect (subtle) scales to circumvent respondent denial or dishonesty. Recommendations for screening and for future research with the SASSI are offered. [source] Validity and Reliability of the Turkish Migraine Disability Assessment (MIDAS) QuestionnaireHEADACHE, Issue 8 2004Mustafa Erta Objectives.,The aim of this study is to assess the comprehensibility, internal consistency, patient-physician reliability, test-retest reliability, and validity of Turkish version of Migraine Disability Assessment (MIDAS) questionnaire in patients with headache. Background.,MIDAS questionnaire has been developed by Stewart et al and shown to be reliable and valid to determine the degree of disability caused by migraine. Design and Methods.,This study was designed as a national multicenter study to demonstrate the reliability and validity of Turkish version of MIDAS questionnaire. Patients applying to 17 Neurology Clinics in Turkey were evaluated at the baseline (visit 1), week 4 (visit 2), and week 12 (visit 3) visits in terms of disease severity and comprehensibility, internal consistency, test-retest reliability, and validity of MIDAS. Since the severity of the disease has been found to change significantly at visit 2 compared to visit 1, test-retest reliability was assessed using the MIDAS scores of a subgroup of patients whose disease severity remained unchanged (up to ±3 days difference in the number of days with headache between visits 1 and 2). Results.,A total of 306 patients (86.2% female, mean age: 35.0 ± 9.8 years) were enrolled into the study. A total of 65.7%, 77.5%, 82.0% of patients reported that "they had fully understood the MIDAS questionnaire" in visits 1, 2, and 3, respectively. A highly positive correlation was found between physician and patient and the applied total MIDAS scores in all three visits (Spearman correlation coefficients were R= 0.87, 0.83, and 0.90, respectively, P < .001). Internal consistency of MIDAS was assessed using Cronbach's , and was found at acceptable (>0.7) or excellent (>0.8) levels in both patient and physician applied MIDAS scores, respectively. Total MIDAS score showed good test-retest reliability (R= 0.68). Both the number of days with headache and the total MIDAS scores were positively correlated at all visits with correlation coefficients between 0.47 and 0.63. There was also a moderate degree of correlation (R= 0.54) between the total MIDAS score at week 12 and the number of days with headache at visit 2 + visit 3, which quantify headache-related disability over a 3-month period similar to MIDAS questionnaire. Conclusion.,These findings demonstrated that the Turkish translation is equivalent to the English version of MIDAS in terms of internal consistency, test-retest reliability, and validity. Physicians can reliably use the Turkish translation of the MIDAS questionnaire in defining the severity of illness and its treatment strategy when applied as a self-administered report by migraine patients themselves. [source] Ensuring Quality Information for Patients: development and preliminary validation of a new instrument to improve the quality of written health care informationHEALTH EXPECTATIONS, Issue 2 2004Beki Moult BA(Hons) MSc Abstract Background, Despite the recent focus on improving the quality of patient information, there is no rigorous method of assessing quality of written patient information that is applicable to all information types and that prescribes the action that is required following evaluation. Objective, The aims of this project were to develop a practical measure of the presentation quality for all types of written health care information and to provide preliminary validity and reliability of the measure in a paediatric setting. Methods, The Ensuring Quality Information for Patients (EQIP) tool was developed through a process of item generation, testing for concurrent validity, inter-rater reliability and utility. Patient information managers and health care professionals tested EQIP in three annual audits of health care leaflets produced by a children's hospital. Results, The final tool comprised 20 items. Kendall's , B rank correlation between EQIP and DISCERN was 0.56 (P = 0.001). There was strong agreement between intuitive rating and the EQIP score (Kendall's , B = 0.78, P = 0.009). Internal consistency using Cronbach's , was 0.80. There was good agreement between pairs of raters (mean , = 0.60; SD = 0.18) with no differences based on types of leaflets. Audits showed significant improvement in the number of leaflets achieving a higher quality EQIP rating over a 3-year period. Conclusions, EQIP demonstrated good preliminary validity, reliability and utility when used by patient information managers and healthcare professionals for a wide variety of written health care information. EQIP uniquely identifies actions to be taken as a result of the quality assessment. Use of EQIP improved the quality of written health care information in a children's hospital. Wider evaluation of EQIP with written information for other populations and settings is recommended. [source] Eliciting patients' preferences for adjuvant chemotherapy in breast cancer: development and validation of a bedside decision-making instrument in a French Regional Cancer CentreHEALTH EXPECTATIONS, Issue 2 2000Marie-Odile Carrère PhD Introduction In developed countries, the physician-patient relationship is moving from a paternalistic model to new decision-making models that take patient preferences into account. Objectives Our aim was to develop a Decision Board (DB) and to test its acceptability in a French Regional Cancer Centre regarding the decision on whether or not to use chemotherapy after surgery in postmenopausal women with breast cancer. This paper presents the development process for this instrument and reports the pretesting phase, as well as the corresponding results. Methods A working group was created with oncologists, psychologists and economists. Following the first phase, i.e. the development process, a first version of the instrument was presented to health professionals. Their feedback led to important modifications of the instrument. The DB was then presented to experienced patients, which resulted in slight changes. The second phase consisted of pretesting the comprehension, internal and across-time consistency of the DB on healthy volunteers. Results The DB was pretested in a group of 40 healthy volunteers. Eighteen respondents chose chemotherapy and 22 chose not to have chemotherapy. Comprehension rates were very high (,87.5%). Internal consistency was assessed considering option attitudes based on outcomes and option attitudes based on process. Women shifted their choices in a predictable way. Across-time consistency was appraised using the test-retest method with Visual Analog Scales. The Intraclass Correlation Coefficient was 0.97. Discussion-conclusion Due to cultural differences, the DB developed in our French Cancer Centre is quite different from the DBs previously developed elsewhere. Our instrument showed good comprehension and consistency properties, which are corroborated by the DB literature. Whether our DB is acceptable for patients with breast cancer must still be tested. Patients' reactions will tell us which type of decision-making model is at work. Further research is needed in order to explore the shared decision-making process and clarify the concept. [source] Development of a Scale to Measure Patients' Trust in Health InsurersHEALTH SERVICES RESEARCH, Issue 1 2002Article first published online: 18 MAR 200 Objective.,To develop a scale to measure patients' trust in health insurers, including public and private insurers and both indemnity and managed care. A scale was developed based on our conceptual model of insurer trust. The scale was analyzed for its factor structure, internal consistency, construct validity, and other psychometric properties. Data Sources/Study Setting.,The scale was developed and validated on a random national sample (n=410) of subjects with any type of insurance and further validated and used in a regional random sample of members of an HMO in North Carolina (n=1152). Study Design.,Factor analysis was used to uncover the underlying dimensions of the scale. Internal consistency was assessed by Cronbach's alpha. Construct validity was established by Pearson or Spearman correlations and t tests. Data Collection.,Data were collected via telephone interviews. Principal Findings.,The 11-item scale has good internal consistency (alpha=0.92/0.89) and response variability (range=11,55, M=36.5/37.0, SD=7.8/7.0). Insurer trust is a unidimensional construct and is related to trust in physicians, satisfaction with care and with insurer, having enough choice in selecting health insurer, no prior disputes with health insurer, type of insurer, and desire to remain with insurer. Conclusions.,Trust in health insurers can be validly and reliably measured. Additional studies are required to learn more about what factors affect insurer trust and whether differences and changes in insurer trust affect actual behaviors and other outcomes of interest. [source] The Apathy Inventory: assessment of apathy and awareness in Alzheimer's disease, Parkinson's disease and mild cognitive impairmentINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 12 2002P. H. Robert Abstract Objective This study was designed to establish the validity and reliability of the apathy inventory (IA), a rating scale for global assessment of apathy and separate assessment of emotional blunting, lack of initiative, and lack of interest. Method Information for the IA can be obtained from the patient or from a caregiver. We evaluated 115 subjects using the IA, consisting of 19 healthy elderly subjects, 24 patients with Mild Cognitive Impairment (MCI), 12 subjects with Parkinson's disease (PD) and 60 subjects with Alzheimer's disease (AD). Results Internal consistency, item reliability, and between,rater reliability were high. A test,retest reliability study demonstrated that caregiver responses to IA questions were stable over short intervals. A concurrent validity study showed that the IA assesses apathy as effectively as the Neuro Psychiatric Inventory apathy domain. In the caregiver-based evaluation, AD subjects had significantly higher scores than controls, both for global apathy score and for the lack of interest dimension. When the AD patients were subdivided according to diagnostic criteria for apathy, apathetic patients had significantly higher scores than non apathetic patients. With the patient-based evaluations, no differences were found among the AD, MCI and control groups. The scores in the patient-based evaluations were only higher for the PD group versus the control subjects. The results also indicated that AD patients had poor awareness of their emotional blunting and lack of initiative. Conclusions The IA is a reliable method for assessing in demented and non-demented elderly subjects several dimensions of the apathetic syndrome, and also the subject's awareness of these symptoms.

Chavez Abstract This article provides the results of the psychometric testing of the Spanish version of CONNECT(-S), a measure of continuity of care in mental health services. CONNECT-S is a multidimensional measure designed for use with seriously mentally ill respondents. Consisting of 12 scales and one single-item indicator, it addresses qualities of interaction in current relationships between mental health service providers and consumers in five conceptual domains: (1) practitioner knowledge of their clients, (2) creating flexibility, (3) practitioner availability, (4) practitioner co-ordination, and (5) smoothing transitions. One-hundred-and-fifty participants took part in the study. Participants were recruited from mental health outpatient clinics in both the Puerto Rican (n = 109) and the San Antonio (n = 41) samples. Internal consistency for scales in a combined site estimate ranged from 0.68 to 0.96. Test-retest reliability ranged from fair to substantial in all but one scale. Concurrent validity hypotheses based on a priori predictions were mostly supported. The Spanish translation and adaptation of CONNECT-S provided sound psychometric results across both sites. CONNECT-S addresses the gap in measurement of continuity of care for the two largest US Latino subgroups, Mexican Americans and Puerto Ricans; and provides an encouraging starting point for a measure that is both relevant and culturally sensitive.

[source] Acceptability and psychometric properties of the Structured Clinical interview for Anorexic-Bulimic Spectrum (SCI-ABS)INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 2 2000Professor Dr M. Mauri In this study we evaluated the psychometric properties of the Structured Clinical Interview for the Anorexic-Bulimic Spectrum (SCI-ABS), including internal consistency, concurrent validity, discriminant validity and test,retest reliability. We also determine acceptability and feasibility of administration of the interview. The SCI-ABS was designed to assess typical and atypical symptoms, behaviours and temperament traits pertaining to eating disorders. The interview included 134 items grouped into nine domains, four of which were divided into subdomains. Data were collected from 372 subjects: 55 psychiatric patients with any eating disorder according to DSM-IV criteria, 118 university students, 141 subjects working out in a gym, and 65 obstetrical patients. Concurrent validity of the instrument was assessed against the Eating Attitude Test (EAT) and the Eating Disorder Inventory (EDI). Thirty-five subjects were also recruited to study the test,retest reliability and 25 women with any eating disorder were administered both the self-report and the interview formats of the SCI-ABS. Internal consistency of domains and subdomains was good. Mean domain and subdomain scores were significantly higher in patients with eating disorders, supporting the discriminant validity of the instrument. Correlation with EAT and EDI indicated good concurrent validity. Test,retest reliability was excellent and the agreement between the interview and self-report formats was satisfactory.

[source] The Ankylosing Spondylitis Quality of Life Questionnaire: validation in a New Zealand cohortINTERNATIONAL JOURNAL OF RHEUMATIC DISEASES, Issue 4 2010Katherine JENKS Abstract Aim:, To examine the validity of the Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) in a New Zealand population with defined axial spondyloarthritis (SpA). Once validated, the ASQoL will be included as an outcome measure in a proposed multicentre New Zealand study. Methods:, Five healthy participants were interviewed to identify any issues related to local dialect or linguistic comprehension of the questionnaire. Cognitive debriefing interviews were conducted with four participants with SpA to assess the relevance and comprehensiveness of the questionnaire. Internal consistency was established by determining the Cronbach's alpha. Finally, convergent validity of the ASQoL was assessed by testing the correlation with the Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and patient global visual analogue scale (VAS) scores in a cohort of 63 SpA patients. Results:, The language used in the ASQoL was considered clear, comprehensible and accessible to speakers of New Zealand English. The questionnaire displayed content validity for patients with SpA. The ASQoL had good internal consistency in the present sample (, = 0.854). A positive correlation was found between the ASQoL and the BASFI (rho = 0.635, P < 0.001), BASDAI (rho = 0.521, P < 0.001) and patient global assessment VAS (rho = 0.546, P < 0.001), providing evidence that the ASQoL has convergent validity among patients with SpA in New Zealand. Test,retest reliability was good over 16 weeks (rho = 0.730, P < 0.001). Conclusions:, The ASQoL has been demonstrated in this study to be feasible, internally consistent and to have content and convergent validity in a New Zealand population of patients with axial spondyloarthritis; it is a measure of quality of life which is both easy to employ and reliable. [source] Using the cardiac depression scale in men recovering from coronary artery bypass surgeryJOURNAL OF CLINICAL NURSING, Issue 11 2009Kathryn M King Aims., To examine the utility and validate the use of the Cardiac Depression Scale in patients who had first-time coronary artery bypass graft surgery. Background., The Beck Depression Inventory, though frequently used, may not be sufficiently sensitive for use in cardiac patients. The Cardiac Depression Scale has been shown to identify the range of depression in medical cardiac patients. Design., Survey. Methods., The Beck Depression Inventory and Cardiac Depression Scale were administered to 120 men at hospital discharge, as well as six, 12 and 36 weeks postoperatively. Cronbach's , scores were calculated for the measures at each point. Changes in scores over time were analysed using repeated measures analysis of variance. Associations between the measures scores were calculated using Pearson product,moment correlations. Agreement between the measures' dichotomised scores (depression/no depression) was examined using Cohen's Kappa statistic. Results., Internal consistency was similar for the Beck Depression Inventory (0·793,0·904) and Cardiac Depression Scale (0·859,0·910). Depression scores decreased over time with the Beck Depression Inventory [F(2·50, 175·29) = 22·27, p < 0·001] and Cardiac Depression Scale [F(2·68, 190·37) = 13·18, p < 0·001]. The measures had similar power [Cohen's f = 0·65 (Beck Depression Inventory) and 0·43 (Cardiac Depression Scale)] to reveal changes over time. The continuous scores were highly correlated at each point [0·737 (p < 0·001),0·819 (p < 0·001)]. However, when dichotomised scores were compared, the chance corrected level of agreement was less impressive [0·198 (p = 0·014),0·381 (p < 0·001)]. Conclusions., The Cardiac Depression Scale may have utility for use with surgical cardiac patients. However, continued examination of this measure of depression is warranted. Relevance to clinical practice., Given the prevalence of depression and its negative impact on coronary artery disease, it is important to identify even mild depression in cardiac patients. Using a measure of depression specifically for cardiac patients, rather than a generic measure, may best accomplish this goal. [source] Validation of the Chinese version of the Satisfaction with the Nursing Home InstrumentJOURNAL OF CLINICAL NURSING, Issue 12 2006Linda YK Lee MNurs Aim., To assess the psychometric properties of the Chinese version of the Satisfaction with the Nursing Home Instrument. Background., Resident's satisfaction has been regarded by the literature as a gold standard for quality of nursing home care. Accurate assessment of resident's satisfaction can provide valuable information for implementation of quality nursing home care. However, there is not a validated Chinese tool to serve the purpose. Design., A cross-sectional descriptive survey design. Methods., Content validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was assessed by the use of expert panel. Construct validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was determined by assessing the correlation between satisfaction with other theoretically related constructs. Internal consistency and stability of the Chinese version of the Satisfaction with the Nursing Home Instrument were determined by Cronbach's method and two-week test,retest reliability. The six-factor structure of the Chinese version of the Satisfaction with the Nursing Home Instrument was assessed by confirmatory factor analysis. Testing was performed on a cluster sample of 330 residents from 16 nursing homes in Hong Kong. Results., The Chinese version of the Satisfaction with the Nursing Home Instrument demonstrated good content validity by having content validity index of 0·93. High construct validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was supported by its significant correlation with depression (r = ,0·42, P = 0·000), health-related quality of life (physical component) (r = 0·16, P = 0·042), health-related quality of life (mental component) (r = 0·41, P = 0·000) and global quality of care (r = 0·49, P = 0·000). The Chinese version of the Satisfaction with the Nursing Home Instrument demonstrated satisfactory internal consistency and good stability by having Cronbach's alpha of 0·79 and intra-class correlation coefficient of 0·94, respectively. The six-factor structure of the Chinese version of the Satisfaction with the Nursing Home Instrument was not fully supported by confirmatory factor analysis. Conclusions., The Chinese version of the Satisfaction with the Nursing Home Instrument is a useful instrument for assessing satisfaction of cognitively intact Chinese nursing home residents. Findings provided initial evidence on its validity and reliability. Further empirical testing is recommended to explore its factor structure. Relevance to clinical practice., The Chinese version of the Satisfaction with the Nursing Home Instrument can provide guidance to enhance delivery of high-quality nursing home care for the Chinese population. [source] Coping and responses to stress in Navajo adolescents: Psychometric properties of the Responses to Stress QuestionnaireJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 4 2004Martha E. Wadsworth This study tested the factor structure of coping and stress responses in Navajo adolescents and examined the reliability and validity of the Responses to Stress Questionnaire (RSQ; Connor-Smith, Compas, Wadsworth, Thomsen, & Saltzman, 2000) with this population. Confirmatory factor analyses revealed that a correlated five-factor model of stress responses using the five factors of the RSQ fit the data well for this group of adolescents. The factor structure of the RSQ did not differ by gender. Internal consistency of the RSQ scales and factors was acceptable, and convergent and discriminant validity were moderate to high. Primary and secondary control engagement coping responses were associated with fewer depressive symptoms in the sample, whereas disengagement coping and involuntary engagement responses were associated with more depressive symptoms. The promising implications for stress and coping research with American Indian adolescents are emphasized. © 2004 Wiley Periodicals, Inc. J Comm Psychol 32: 391,411, 2004. [source] Brief scale measuring patient preparedness for hospital discharge to home: Psychometric properties,JOURNAL OF HOSPITAL MEDICINE, Issue 6 2008James F. Graumlich MD Abstract BACKGROUND: Adverse events occur when patients transition from the hospital to outpatient care. For quality improvement and research purposes, clinicians need appropriate, reliable, and valid survey instruments to measure and improve the discharge processes. OBJECTIVE: The object was to describe psychometric properties of the Brief PREPARED (B-PREPARED) instrument to measure preparedness for hospital discharge from the patient's perspective. METHODS: The study was a prospective cohort of 460 patient or proxy telephone interviews following hospital discharge home. We administered the Satisfaction with Information about Medicines Scale and the PREPARED instrument 1 week after discharge. PREPARED measured patients' perceptions of quality and outcome of the discharge-planning processes. Four weeks after discharge, interviewers elicited emergency department visits. The main outcome was the B-PREPARED scale value: the sum of scores from 11 items. Internal consistency, construct, and predictive validity were assessed. RESULTS: The mean B-PREPARED scale value was 17.3 ± 4.2 (SD) with a range of 3 to 22. High scores reflected high preparedness. Principal component analysis identified 3 domains: self-care information, equipment/services, and confidence. The B-PREPARED had acceptable internal consistency (Cronbach's alpha 0.76) and construct validity. The B-PREPARED correlated with medication information satisfaction (P < 0.001). Higher median B-PREPARED scores appropriately discriminated patients with no worry about managing at home from worriers (P < 0.001) and predicted patients without emergency department visits after discharge from those who had visits (P = 0.011). CONCLUSIONS: The B-PREPARED scale measured patients' perceptions of their preparedness for hospital discharge home with acceptable internal consistency and construct and predictive validity. Brevity may potentiate use by patients and proxies. Clinicians and researchers may use B-PREPARED to evaluate discharge interventions.

[source] The ComFor: an instrument for the indication of augmentative communication in people with autism and intellectual disabilityJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 9 2006I. Noens Abstract Background The ComFor (Forerunners in Communication) is an instrument to explore underlying competence for augmentative communication. More specifically, it measures perception and sense-making of non-transient forms of communication at the levels of presentation and representation. The target group consists primarily of individuals with autism and intellectual disability (ID) without or with only limited verbal communication. The ComFor is suitable for children and adults with a developmental level between 12 and 60 months. This paper describes the theoretical framework and structure of the ComFor, the results of a study on its psychometric properties and its clinical uses. Method The ComFor was tested on a sample of 623 children and adults from the Netherlands and Flanders: a group with autism and ID (n = 310); a group with ID without autism (n = 174); and a control group of typically developing children (n = 139). Results The data generally support the reliability and validity of the ComFor. Internal consistency, inter-rater and test,retest reliability were found to be good. Construct validity (internal structure, convergent and divergent patterns) was established in different ways. The criterion-related validity has yet to be established, as predictive data are not available at the moment. Conclusion Taken together, the results indicate that the ComFor is a promising instrument to explore underlying competence for augmentative communication. Areas for future research are outlined and the clinical relevance is discussed. [source] Technical and non-technical skills can be reliably assessed during paramedic simulation trainingACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2009T. VON WYL Background: Medical teams depend on technical skills (TS) as well as non-technical skills (NTS) for successful management of critical events. Simulated scenarios are an opportunity for presentation of similar crisis situations. The aim of this study was to test whether TS and NTS are assessable with satisfactory interrater reliability (IRR) during a regular paramedic training. Methods: Thirty paramedics were rated by two independent observers using video-recording and previously validated checklists while managing two simulated emergency scenarios as a team of two. The observed items of the team's TS included type, order, and time of adequate medical care. The NTS were restricted to six team-oriented dimensions. The IRR was quantified by calculating the intraclass correlation coefficient (ICC). The z -transformed values of the TS and NTS were correlated by Pearson's correlation. Internal consistency was controlled using Cronbach's ,. Results: The average measures ICC for the IRR was between 0.97 [95% confidence interval (CI) 0.91,0.99] and 0.98 (95% CI 0.94,0.99) for the TS sum-score, and was 0.94 (95% CI 0.87,0.97) for the NTS sum-score; the Cronbach's , of this NTS sum-score was 0.86. There is a positive correlation between the normalised TS and NTS sum-scores (r=0.53; P<0.05). Conclusion: Assessment of TS and NTS is feasible and reliable during paramedic training in emergency scenarios. TS can be reliably assessed by one trained observer; for NTS, two trained raters provide a suitable condition for excellent observations. There is a significant positive correlation between TS and NTS. [source] Validation of a brief symptom questionnaire (ReQuest in Practice) for patients with gastro-oesophageal reflux diseaseALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 9 2008G. RUBIN Summary Background, A clinical need exists for a means of assessing symptom control in patients with gastro-oesophageal reflux disease. The ReQuest questionnaire has been extensively validated for symptom assessment in both erosive and non-erosive gastro-oesophageal reflux disease but was designed for research purposes. We derived a shorter version (ReQuest in Practice) that would be more convenient for clinical practice. Aim, To validate ReQuest in Practice in patients suffering from gastro-oesophageal reflux disease. Methods, Multicentre, non-interventional, crossover comparison. Patients completed ReQuest in Practice followed by ReQuest or vice versa. Before and after a planned endoscopy, patients completed the health-related quality of life questionnaire GERDyzer. Internal consistency and the Intraclass Correlation Coefficient were calculated. Construct validity was evaluated by correlation with ReQuest and GERDyzer. Results, There was high internal consistency of ReQuest in Practice (Cronbach's alpha: 0.9) and a high Intraclass Correlation Coefficient of 0.99. The measurement error of ReQuest in Practice was 4.1. High correlation between ReQuest in Practice and ReQuest (Spearman correlation coefficient: 0.9) and GERDyzer (Spearman correlation coefficient: 0.8) demonstrated construct validity. Conclusions, ReQuest in Practice was proven to be valid and reliable. Its close correlation with ReQuest makes it a promising tool to guide the clinical management of patients across the full spectrum of both erosive and non-erosive gastro-oesophageal reflux disease.

Bardhan Summary Background :,Reflux Questionnaire (ReQuest), a newly developed gastro-oesophageal reflux disease-sensitive scale, can be used to reliably evaluate the effect of treatment on gastro-oesophageal reflux disease symptoms. Aim :,International validation of this scale, in patients suffering from endoscopy-negative gastro-oesophageal reflux disease. Methods :,In this open, multicentre and multinational clinical trial 840 endoscopy-negative gastro-oesophageal reflux disease patients received pantoprazole 20 mg daily for 28 days. The long and short versions of ReQuest were completed both in the pre-treatment and treatment phases. For scale development an item reduction analysis was performed. Internal consistency, test,retest reliability and responsiveness were calculated for psychometric analysis. Construct validity was evaluated by comparison with the Gastrointestinal Symptom Rating Scale and the Psychological General Well-being questionnaire by means of correlation coefficients. Results :,Factor analyses confirmed the content validity of both long and short version of ReQuest. Psychometric calculations proved high internal consistency (Cronbach's alpha: 0.9), test,retest reliability [Intraclass Correlation Coefficient: 0.9 (long vs. long) and 0.8 (short vs. short)], and responsiveness (Responsiveness Index 320.3) of the scale, for which also good construct validity was achieved (correlation coefficient: Gastrointestinal Symptom Rating Scale ,0.6; Psychological General Well-being ,0.4). Conclusion :,ReQuest proved valid, reliable, and responsive in this multinational clinical trial to evaluate treatment response in endoscopy-negative gastro-oesophageal reflux disease patients. [source] Quality of life in functional dyspepsia: responsiveness of the Nepean Dyspepsia Index and development of a new 10-item short formALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2 2001N. J. Talley Background: The Nepean Dyspepsia Index is a reliable and valid measure of quality of life in functional dyspepsia, but responsiveness has been little studied. The Nepean Dyspepsia Index originally contained 42 items designed to measure impairment of a subject's ability to engage in relevant aspects of their life because of dyspepsia, and their enjoyment of these aspects; in addition, the individual importance of areas was assessed. It was subsequently shortened to 25 items, yielding five sub-scales. Aim: To test the Nepean Dyspepsia Index's responsiveness and develop a responsive, very short form. Methods: A randomized, double-blind controlled trial was performed in 589 patients with documented functional dyspepsia. Symptoms and quality of life were measured at baseline, 2 and 4 weeks. Responsiveness of the Nepean Dyspepsia Index quality-of-life section was evaluated by correlation with symptom scores and calculation of standardized changes in scores. Two items from each sub-scale which best represented the area of life (by factor loadings) were selected to create the 10-item short form (SF; short form-Nepean Dyspepsia Index). Internal consistency was assessed by Cronbach's alpha and responsiveness was assessed as above. Results: The Nepean Dyspepsia Index quality-of-life scales demonstrated excellent responsiveness to change in both the active and placebo arms (standardized response means all > 1.0). The Nepean Dyspepsia Index accounted for only 8% of the variance in percentage change in symptoms (by visual analogue scales), indicating that it was evaluating areas of life not covered by symptoms. The 10-item short form had adequate internal consistency (all scales , 0.70) and all strongly (and significantly) correlated with the long form sub-scales; it was also highly responsive. Conclusion: The Nepean Dyspepsia Index is a responsive disease-specific quality-of-life measure; the 10-item short form can be applied in clinical trials of functional dyspepsia. [source] Assessing fear of falling: Can a short version of the Activities-specific Balance Confidence scale be useful?MOVEMENT DISORDERS, Issue 12 2006Chava Peretz PhD Abstract We present the process of further validation of the 16-item Activities-specific Balance Confidence scale (ABC-16) and a short version (ABC-6) derived by us, to assess balance confidence and fear of falling (FOF). The ABC-16 was administrated to three groups who were anticipated to have a range of balance confidence: 70 patients with higher level gait disorders (HLGDs), 68 healthy controls, and 19 patients with Parkinson's disease (PD). Item reduction was based on identifying items with the lowest scores (high FOF) among the patients. Internal consistency and discriminative validity were assessed using Cronbach's alpha and logistic regression, respectively. The intraclass correlation (ICC) between the short and long versions was assessed using a mixed model approach, accounting for the difference between the scores of the two versions. Six items were found to reflect the most frightening conditions, especially in the patient groups, and to form the short version (ABC-6). Internal consistency of the ABC-16 and ABC-6 were high in the three groups: Cronbach's alpha was between 0.83 and 0.91 and 0.81 and 0.90, respectively. Compared to the control group, the sensitivity of the ABC-16 was 96% for identification of patients with HLGDs (greatest FOF) and 58% for identification of PDs (moderate FOF), based only on the ABC scores. Similar values were obtained for the short version, i.e., 91% for HLGDs and 53% for PDs. ICCs between the short and the long versions was 0.88 (HLGDs), 0.83 (PDs), and 0.78 (Controls). To conclude, the short version of the ABC has properties analogous to the parent questionnaire and is apparently useful in assessing FOF. © 2006 Movement Disorder Society [source] Development and validation of the Unified Multiple System Atrophy Rating Scale (UMSARS)MOVEMENT DISORDERS, Issue 12 2004Gregor K. Wenning MD Abstract We aimed to develop and validate a novel rating scale for multiple system atrophy (Unified Multiple System Atrophy Rating Scale - UMSARS). The scale comprises the following components: Part I, historical, 12 items; Part II, motor examination, 14 items; Part III, autonomic examination; and Part IV, global disability scale. For validation purposes, 40 MSA patients were assessed in four centers by 4 raters per center (2 senior and 2 junior raters). The raters applied the UMSARS, as well as a range of other scales, including the Unified Parkinson's Disease Rating Scale (UPDRS) and the International Cooperative Ataxia Rating Scale (ICARS). Internal consistency was high for both UMSARS-I (Crohnbach's alpha = 0.84) and UMSARS-II (Crohnbach's alpha = 0.90) sections. The interrater reliability of most of the UMSARS-I and -II items as well as of total UMSARS-I and -II subscores was substantial (k (w) = 0.6,0.8) to excellent (k (w) > 0.8). UMSARS-II correlated well with UPDRS-III and ICARS (rs > 0.8). Depending on the degree of the patient's disability, completion of the entire UMSARS took 30 to 45 minutes. Based on our findings, the UMSARS appears to be a multidimensional, reliable, and valid scale for semiquantitative clinical assessments of MSA patients. © 2004 Movement Disorder Society [source] Patient reported and anatomical outcomes after surgery for pelvic organ prolapse,,NEUROUROLOGY AND URODYNAMICS, Issue 3 2009Ahmed S. El-Azab Abstract Aim Primary aim was to modify Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ) to assess pelvic organ prolapse (POP) in Arabic Muslim women. Secondary aim was to compare functional and anatomical outcomes of POP repair. Methods Questionnaire. A characteristic (prayer) was added to PFIQ. Linguistic validation of questionnaires was then done. Twenty cases were enrolled in a pilot study to test internal consistency and reliability. Subsequent study. Prospective study included women with symptomatic POP,,,stage II. History, examination by POP-Q, and administration of PFDI and PFIQ, were done before and 6 months after surgery. Results Questionnaire. Internal consistency of added question was good (Cronbach ,,=,0.78). Test,retest reliability of individual PFIQ items was variable. Subsequent Study. Between September 2004 and February 2007, 78 consecutive women were included. Cystocele, rectocele, and no site predominated in 74.4%, 17.9% and 7.7% of cases, respectively. Preoperatively 19.2%, 15.4% and 47.4% reported stress, urge, and mixed incontinence, respectively. Overall and individual urinary symptoms scores improved significantly after surgery. There were significant improvements in individual symptoms of constipation, splint to defecate and losing not well formed stools. Low self-esteem was most negative impact of prolapse on quality of life (QoL) followed by prayer. After surgery 90% of subjects had anatomical cure. After surgery, QoL issues are significantly related to anatomic location of prolapse as determined by POP-Q. Conclusions Modified PFIQ and PFDI are suitable to assess POP among Muslim women. Postoperatively, many prolapse-related symptoms and QoL significantly improve after surgery on the short term with an anatomic cure rate of 90%. Neurourol.

[source] Measuring health-related quality of life in women with urogenital dysfunction: The urogenital distress inventory and incontinence impact questionnaire revisitedNEUROUROLOGY AND URODYNAMICS, Issue 2 2003C. Huub van der Vaart Abstract Aims Symptoms of urogenital dysfunction are known to negatively affect health-related quality of life in women. To assess effectiveness of treatment, it is currently recommended to include measurements of quality of life in outcome analysis. One of the questionnaires that is commonly used is the combination of the Urogenital Distress Inventory (UDI) and Incontinence Impact Questionnaire (IIQ). Unfortunately, the validity of the UDI and IIQ has only been tested in highly selected subgroups of female patients. Therefore, it is unclear whether this questionnaire is suitable for use in populations with different characteristics. Methods We analyzed the scale construction and validity of the UDI and IIQ in a random sample of 2,042 women, aged 20,70 years old and a clinical sample of 196 women. Results Our results show that the UDI can be divided into five subscales, namely discomfort/pain, urinary incontinence, overactive bladder, genital prolapse, and obstructive micturition. The internal consistency (Cronbach's alpha) ranged between 0.74 and 0.82. In addition to the original four subscales of the IIQ (mobility, physical, social, and emotional functioning), we identified a fifth subscale with four items about embarrassment. Internal consistency of these subscales ranged between 0.83 and 0.93. In addition to the internal consistency, we tested the criterion and construct validity of these new subscale division. Conclusions We found these subscales to be reliable and of clinical use. It is recommended to use the revised UDI and IIQ in outcome analysis of treatments for urogenital symptoms in women.

[source] Comparing the Psychometric Properties of the Checklist of Nonverbal Pain Behaviors (CNPI) and the Pain Assessment in Advanced Dementia (PAIN-AD) InstrumentsPAIN MEDICINE, Issue 3 2010FAAN, Mary Ersek PhD Abstract Objective., To examine and compare the psychometric properties of two common observational pain assessment tools used in persons with dementia. Design., In a cross-sectional descriptive study nursing home (NH) residents were videotaped at rest and during a structured movement procedure. Following one training session and one practice session, two trained graduate nursing research assistants independently scored the tapes using the two pain observation tools. Setting., Fourteen NHs in Western Washington State participating in a randomized controlled trial of an intervention to enhance pain assessment and management. Participants., Sixty participants with moderate to severe pain were identified by nursing staff or chosen based on the pain items from the most recent Minimum Data Set assessment. Measures., Checklist of Nonverbal Pain Indicators (CNPI) and the Pain Assessment in Advanced Dementia (PAINAD), demographic and pain-related data (Minimum Data Set), nursing assistant reports of participants' usual pain intensity, and Pittsburgh Agitation Scale. Results., Internal consistency for both tools was good except for the CNPI at rest for one rater. Inter-rater reliability for pain presence was fair (K = 0.25 for CNPI with movement; K = 0.31 for PAINAD at rest) to moderate (K = 0.43 for CNPI at rest; K = 0.54 for PAINAD with movement). There were significant differences in mean CNPI and PAINAD scores at rest and during movement, providing support for construct validity. However, both tools demonstrated marked floor effects, particularly when participants were at rest. Conclusions., Despite earlier studies supporting the reliability and validity of the CNPI and the PAINAD, findings from the current study indicate that these measures warrant further study with clinical users, should be used cautiously both in research and clinical settings and only as part of a comprehensive approach to pain assessment. [source] Japanese version of the Body Attitude Test: Its reliability and validityPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 5 2003Akiko Kashima Abstract The Body Attitude Test (BAT) was developed by Probst et al. (1995) for female patients with eating disorders (ED). This test measures the subjective body experience and attitudes toward one's body. The present authors have developed the Japanese version of the BAT and the purpose of the present paper was to investigate its reliability and validity in control (CON, n = 599) and ED patients (n = 46). The ED patients consisted of 21 anorexia nervosa, restricting type (AN-R) patients and 25 bulimia nervosa (BN) patients. Internal consistency was determined with Cronbach's , coefficient in CON. Factor analysis was conducted on BAT ratings given by CON. Factor analysis indicated that BAT was composed of two factors. These were body dissatisfaction (factor 1) and lack of familiarity with one's body (factor 2). A comparison was made among AN-R, BN, and CON. Bulimia nervosa had a significantly higher score than the other two groups. The BAT scores of ED patients correlated significantly with the Self -rating Depression Scale, and State,Trait Anxiety Inventory. These results show that ED patients have negative feelings toward their own body, similar to the findings in the original report. On factor analysis, however, it was not possible to distinguish between negative appreciation of body size and general body dissatisfaction as described in the original report. The authors also examine influences on this difference from a cross-cultural view point. [source] Reliability and validity of the General Health Questionnaire (GHQ-12) among urological patients: A Malaysian studyPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 5 2001Kia Fatt Quek MPHIL Abstract This present study was undertaken to validate the English version of the General Health Questionnaire (GHQ-12) in urological patients. Validity and reliability were studied in patients with lower urinary tract symptoms (LUTS) and patients without LUTS. Reliability was evaluated using the test,retest method and internal consistency was assessed using Cronbach's alpha. Sensitivity to change was expressed as the effect size in the pre-intervention versus post-intervention score in additional patients with benign prostatic hyperplasia (BPH) who underwent transurethral resection of the prostate (TURP). Internal consistency was excellent. A high degree of internal consistency was observed for each of the 12 items with Cronbach's alpha value of 0.37,0.79, while total scores was 0.79 in the population study. Test,retest correlation coefficient for the 12 items score were highly significant. Intraclass correlation coefficient was high (0.35,0.79). It showed a high degree of sensitivity and specificity to the effects of treatment. A high degree of significant level between baseline and post-treatment scores were observed across all 12 items in the treatment cohort but not in the control group. The GHQ-12 is suitable, reliable, valid and sensitive to clinical change in urological disorders. [source] The mental adjustment to cancer (MAC) scale: French replication and assessment of positive and negative adjustment dimensionsPSYCHO-ONCOLOGY, Issue 1 2003Sandrine Cayrou The Mental Adjustment to Cancer (MAC) scale was validated on a heterogeneous French sample of 317 cancer patients. Internal consistency was satisfactory for the original subscales (, coefficients=0.62,0.80), except for the Fatalism subscale (,=0.40). The intercorrelations of the subscales and the correlations between the subscales and Anxiety and Depression criteria were congruent with the values reported in the literature. Multidimensional Scaling revealed three positive and three negative subsets of items revealing adjustment to cancer. Congeneric factor analysis of the subsets was performed with LISREL 8.3 and only three of them (after discarding certain items) were retained: Fighting Spirit (FS) Hopelessness/Helplessness (HH) and Anxious Preoccupation (AP). A confirmatory hierarchical factor analysis on the 21 items included showed that FS measured positive adjustment to cancer and HH and AP measured negative adjustment. A differential adjustment hypothesis was proposed in order to explain the stability and instability of the measures of the diverse constructs. The three revised subscales showed the same validity pattern as the corresponding original scales, but the magnitude of the correlations was considerably improved with respect to the original subscales. The practical and the theoretical importance of FS, HH and AP are emphasized. Copyright © 2003 John Wiley & Sons, Ltd. [source] Measuring Community Coalition Effectiveness Using the ICE© InstrumentPUBLIC HEALTH NURSING, Issue 1 2006Mary E. Cramer ABSTRACT This article presents the development and psychometric testing of the Internal Coalition Effectiveness (ICE) instrument, which was based on the conceptual model Internal Coalition Outcome Hierarchy. Sixty-one items were derived from literature about successful coalitions, and the ICE instrument was tested for reliability and validity. A national panel of eight experts conducted content validity. Remaining tests involved a sample of 61 members and leaders of a large midwestern coalition (77% response rate, n = 47). Content validity involved a two-stage process for rigorous item development and quantification (0.88, p < 0.05). Internal consistency was based on bivariate Pearson's correlation of 0.30,0.70 for two-item scales and Cronbach's ,(, = 0.70). Construct validity was assessed by correlation analysis, independent Student's t tests, and informal coalition feedback. The final 30-item version of ICE is psychometrically sound. Findings were shared with the local coalition, and, in support of the instrument's validity, members and leaders found this information useful for promoting coalition sustainability by identifying internal strengths and areas for improvement. The ICE instrument adds to the body of literature by measuring critical constructs of coalition effectiveness and has significant application for public health nurses working as evaluators for coalitions engaged in community health programing.
