Care dependency of hospitalized children: testing the Care Dependency Scale for Paediatrics in a cross-cultural comparison

JOURNAL OF ADVANCED NURSING, Issue 2 2009
Hanan Tork
Abstract Title.,Care dependency of hospitalized children: testing the Care Dependency Scale for Paediatrics in a cross-cultural comparison. Aim., This paper is a report of a study to examine the psychometric properties of the Care Dependency Scale for Paediatrics in Germany and Egypt and to compare the care dependency of school-age children in both countries. Background., Cross-cultural differences in care dependency of older adults have been documented in the literature, but little is known about the differences and similarities with regard to children's care dependency in different cultures. Method., A convenience sample of 258 school-aged children from Germany and Egypt participated in the study in 2005. The reliability of the Care Dependency Scale for Paediatrics was assessed in terms of internal consistency and interrater reliability. Factor analysis (principal component analysis) was employed to verify the construct validity. A Visual Analogue Scale was used to investigate the criterion-related validity. Findings., Good internal consistency was detected both for the Arabic and German versions. Factor analysis revealed one factor for both versions. A Pearson's correlation between the Care Dependency Scale for Paediatrics and Visual Analogue Scale was statistically significant for both versions indicating criterion-related validity. Statistically significant differences between the participants were detected regarding the mean sum score on the Care Dependency Scale for Paediatrics. Conclusion., The Care Dependency Scale for Paediatrics is a reliable and valid tool for assessing the care dependency of children and is recommended for assessing the care dependency of children from different ethnic origins. Differences in care dependency between German and Egyptian children were detected, which might be due to cultural differences. [source]


The 14-item Michigan Diabetes Knowledge Test: translation and validation study of the Malaysian version

PRACTICAL DIABETES INTERNATIONAL (INCORPORATING CARDIABETES), Issue 6 2010
HK Al-Qazaz MSc
Abstract The aims of this study were to translate the Michigan Diabetes Knowledge Test (MDKT) into the Malaysian language, and to examine the psychometric properties of the Malaysian version. A standard translation procedure was used to create the Malaysian version of the MDKT from the original English version. A convenience sample of 307 outpatients with type 2 diabetes was identified between May and October 2009. All data were collected from the Penang General Hospital, Penang, Malaysia. Instruments consisted of the Malaysian version of the MDKT and a socio-demographic questionnaire. Medical records were reviewed for haemoglobin A1c (HbA1c) levels and other clinical data. Reliability was tested for internal consistency using Cronbach's alpha coefficient. Employing the recommended scoring method, the mean±SD of MDKT scores was 7.88±3.01. Good internal consistency was found (Cronbach's alpha = 0.702); the test-retest reliability value was 0.894 (p<0.001). For known group validity, a significant relationship between MDKT categories and HbA1c categories (chi-square = 21.626; p,0.001) was found. The findings of this validation study indicate that the Malaysian version of the MDKT is a reliable and valid measure of diabetes knowledge which can now be used in clinical and research practice.

Psychometric properties of the Beck Depression Inventory-II with incarcerated male offenders aged 18,21 years

CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2008
Emma J. Palmer
Background,The Beck Depression Inventory , Second Edition (BDI-II) is a self-report measure of depression. Studies have shown it to have good psychometric properties with adult and adolescent clinical and non-clinical populations. However, this research has mostly been conducted with North American samples. Aims/hypotheses,To examine the psychometric characteristics of the BDI-II with male young adult offenders in the UK. Methods,The BDI-II was administered to 117 incarcerated male young adult offenders aged 18,21 years from the UK. Results,The BDI-II showed good internal consistency and concurrent validity. Factor analysis revealed two factors, relating to cognitive-affective items and somatic items. The items loading on the two factors were very similar to those found in a North American adolescent (13,17 years) psychiatric inpatient sample. Conclusions and implications for future research,The findings suggest that the BDI-II can be used with confidence in young adult male offenders. It would be useful to confirm its psychometric properties in other offender samples and establish offender population norms. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Portuguese version of Corah's Dental Anxiety Scale: transcultural adaptation and reliability analysis

DEPRESSION AND ANXIETY, Issue 7 2007
Li Wen Hu Ms.C.
Abstract This study explores the psychometric properties of the Portuguese version of Corah's Dental Anxiety Scale (DAS), an instrument designed to assess the manifestations of dental anxiety. The DAS has been translated into several languages, but no adaptation and reliability analysis of the Portuguese version of the scale has yet been carried out. A total of 747 Brazilian undergraduate students participated in this study. The instrument proved to have good internal consistency and test,retest reliability. Furthermore, we observed that women are more anxious during dental treatment routines compared to men. Our findings suggest that the Portuguese version of DAS is a reliable instrument for assessing adults' dental anxiety traits, and can be used for both clinical and research purposes.

Kassam A, Glozier N, Leese M, Henderson C, Thornicroft G. Development and responsiveness of a scale to measure clinicians' attitudes to people with mental illness (medical student version). Objective:, We report the rationale, reliability, validity and responsiveness studies of the Mental Illness: Clinicians' Attitudes (MICA) Scale, a 16-item scale designed to measure attitudes of health care professionals towards people with mental illness. Method:, Items were generated through focus groups with service users, carers, medical students and trainee psychiatrists. Psychometric testing was completed in a number of student samples. The responsiveness of the scale was tested after a 1.5 h mental illness stigma related intervention with medical students. Results:, The MICA scale showed good internal consistency, , = 0.79. The test,retest reliability (concordance) was 0.80 (95% CI: 0.68,0.91). The standardised response mean for the scale was 0.4 (95% CI 0.02,0.8) after a mental illness related stigma intervention. Conclusion:, The MICA scale is a responsive, reliable and valid tool, which can be used in medical education and mental health promotion settings and studies. [source]


Appraisal of Social Concerns: A cognitive assessment instrument for social phobia

DEPRESSION AND ANXIETY, Issue 4 2004
Michael J. Telch Ph.D.
Abstract The current study describes the validation of a new cognitive assessment measure for social phobia, entitled the Appraisal of Social Concerns (ASC). Item content is relevant to a range of social situations. The ASC can be used to tailor interventions to patients' idiosyncratic concerns. Data are presented from both clinical (n=71) and non-clinical (n=550) samples. Preliminary data indicate that the ASC has good internal consistency and test,retest reliability. The construct validity of the ASC is comparable to that of well-established measures in use with social phobics. A strength of the ASC is its sensitivity to the effect of treatment. An exploratory factor analysis yielded three factors tapping concerns about negative evaluation, observable symptoms, and social helplessness. Subscale scores were strongly correlated. Preliminary findings suggest that the ASC is a psychometrically sound, time efficient instrument that can be used for both clinical and research purposes.

The validity of an Australian modification of the AUDIT questionnaire

DRUG AND ALCOHOL REVIEW, Issue 2 2001
LOUISA J. DEGENHARDT
Abstract The Alcohol Use Disorders Identification Test (AUDIT) has been used widely and is reported to be superior to conventional questionnaires in detection of current hazardous and harmful alcohol use. We assessed the validity of an Australian modification of the AUDIT (the AusAUDIT), which has been employed widely in Australian and New Zealand early intervention programmes. We used a cross-sectional study of 370 subjects from the follow-up phase of a randomized controlled trial of early intervention to reduce hazardous alcohol consumption. Scores on the AusAUDIT were compared against 12-month ICD-10 diagnoses of harmful alcohol use and dependence, as determined by the Composite International Diagnostic Interview, and against self-report of alcohol consumption exceeding Australian National Health and Medical Research Council (NH&MRC) recommended limits. AusAUDIT had good internal consistency and discriminated significantly between persons meeting criteria for ICD-10 alcohol use disorders, and drinkers who did not. At currently recommended cut-off scores, AusAUDIT detected more than 85% of people meeting criteria for ICD-10 alcohol use disorders, or drinking over NH&MRC recommended limits, but its specificity was limited (29% in men, and 58% in women for drinking over NH&MRC limits). No subset of questions performed as well as the full AusAUDIT in detection of drinking problems, but the alcohol consumption items provided a reasonable screen for drinking over NH&MRC limits. We conclude that AusAUDIT is effective in detecting problematic drinking, but positive cases should be confirmed by clinical assessment. The findings illustrate the need for validation of questionnaire modifications, and the difficulty in increasing test sensitivity without reducing specificity. [source]


Assessing motivation to change in bulimia nervosa: the bulimia nervosa stages of change questionnaire

EUROPEAN EATING DISORDERS REVIEW, Issue 1 2007
Esteve Martinez
Abstract Objective To assess motivation to change in adolescent patients with bulimia nervosa through the Bulimia Nervosa Stages of Change Questionnaire (BNSOCQ), an instrument adapted from the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ) already validated in anorexic patients. Method Subjects were 30 bulimia nervosa patients (mean age,=,16.3 years) who were receiving treatment at an eating disorders unit. The evaluation instruments were: the BNSOCQ, the Eating Disorders Inventory (EDI-2) and the Beck Depression Inventory (BDI). The BNSOCQ was re-administered 1 week later to evaluate test-retest reliability. Results The BNSOCQ demonstrated good internal consistency (Cronbach's alpha,=,0.94) and one week test-retest reliability (Pearson's r,=,0.93). Negative significant correlations were found between the BNSOCQ and several EDI-2 scales (Pearson's r between ,0.51 and ,0.84) and the BDI (r,=,,0.74). Conclusion The study provides initial support for the reliability and validity of the BNSOCQ as a self-report instrument for assessing motivation to change in adolescents with bulimia nervosa.

The utility of the Dutch Arthritis Impact Measurement Scales 2 for assessing health status in individuals with haemophilia: a pilot study

HAEMOPHILIA, Issue 6 2000
N. L. U. Van Meeteren
The aim of this pilot study was to examine the usefulness of the Dutch version of the Arthritis Impact Measurement Scales 2 (D-AIMS2)in assessing the health status of Dutch individuals with haemophilia. Sixty-eight individuals with mild, moderate, and severe haemophilia attending our clinic for their annual check-up participated. They first completed the Canadian Occupational Performance Measure (COPM). The D-AIMS2 was filled in afterwards at home. With the COPM, individuals rated their specific problematic activities of daily life (ADL), as well as the severity and importance of each problem. The D-AIMS2 is a comprehensive, self-administered questionnaire that evaluates functional health status. Fifty-seven individuals completed and returned the D-AIMS2. Reliability analysis demonstrated good internal consistency for the scales (Cronbach's ,=0.76,1.00), as well as for the components (,=0.80,0.88), except for the component ,social interaction' (,=0.44). Criterion validity of the D-AIMS2 was assessed by comparison with COPM outcomes; 80% of the problematic ADLs were included in the questionnaire, 20% were missing. Correlations between the D-AIMS2 components ,physical health' and ,symptoms' with predicted scores of those individuals by a highly experienced physiotherapist (r=0.63 and 0.53, respectively) substantiated its concurrent validity. Based on these results we concluded that the D-AIMS2, with minor adjustments, can be an appropriate tool for assessing the health status of Dutch haemophilia patients. [source]


Trust in the Medical Profession: Conceptual and Measurement Issues

HEALTH SERVICES RESEARCH, Issue 5 2002
Mark A Hall
Objective. To develop and test a multi-item measure for general trust in physicians, in contrast with trust in a specific physician. Data Sources. Random national telephone survey of 502 adult subjects with a regular physician and source of payment. Study Design. Based on a multidimensional conceptual model, a large pool of candidate items was generated, tested, and revised using focus groups, expert reviewers, and pilot testing. The scale was analyzed for its factor structure, internal consistency, construct validity, and other psychometric properties. Principal Findings. The resulting 11-item scale measuring trust in physicians generally is consistent with most aspects of the conceptual model except that it does not include the dimension of confidentiality. This scale has a single-factor structure, good internal consistency (alpha=.89), and good response variability (range=11,54; mean=33.5; SD=6.9). This scale is related to satisfaction with care, trust in one's physician, following doctors' recommendations, having no prior disputes with physicians, not having sought second opinions, and not having changed doctors. No association was found with race/ethnicity. While general trust and interpersonal trust are qualitatively similar, they are only moderately correlated with each other and general trust is substantially lower. Conclusions. Emerging research on patients' trust has focused on interpersonal trust in a specific, known physician. Trust in physicians in general is also important and differs significantly from interpersonal physician trust. General physician trust potentially has a strong influence on important behaviors and attitudes, and on the formation of interpersonal physician trust. [source]


Development of a Scale to Measure Patients' Trust in Health Insurers

HEALTH SERVICES RESEARCH, Issue 1 2002
Article 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.

A validity and reliability study of assessment and screening for sustained withdrawal reaction in infancy: The Alarm Distress Baby scale,

INFANT MENTAL HEALTH JOURNAL, Issue 5 2001
Antoine Guedeney
Sustained withdrawal behavior in infancy is an important alarm signal to draw attention to both organic and relationship disorders. A withdrawal scale, the Alarm Distress Baby scale (ADBB), for infants between 2 and 24 months of age was built. This article describes the construction of the scale and the assessment of its psychometric properties. The ADBB has good content validity, based on the advice of seven experts. The scale has good criterion validity: first, as a measure of the infant's withdrawal reaction, with a very good correlation between nurse and pediatrician on the ADBB (rs = 0.84), and second, as a screening procedure for detecting the developmental risk of the infant. The cutoff score of 5 with a sensitivity of 0.82 and a specificity of 0.78 was determined to be optimal for screening purposes. The scale has good construct validity, with good convergent validity with both the Spitz (1951) and the Herzog & Rathbun (1982) lists of symptoms of infant depression (rs = 0.61 and 0.60, respectively). Exploratory factor analysis showed two different factors, consistent with the scale's construct. Reliability was satisfactory with good internal consistency for both subscales (the Cronbach , = 0.80 for the first subscale and 0.79 for the second) and for the global scale (, = 0.83). The test-retest procedure showed good stability over time (rs = 0.90 and 0.84 for the two different raters). The scale could be used in different clinical settings, provided a sufficient level of social stimulation is given to the infant in a relatively brief period of time. The scale can be used by nurses and psychologists or by medical doctors after a short period of training. © 2001 Michigan Association for Infant Mental Health. [source]


Construction and validation of a patient- and user-friendly nursing home version of the Geriatric Depression Scale,

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 9 2007
K. Jongenelis
Abstract Objective To construct a patient- and user-friendly shortened version of the Geriatric Depression Scale (GDS) that is especially suitable for nursing home patients. Methods The study was carried out on two different data bases including 23 Dutch nursing homes. Data on the GDS (n,=,410), the Mini Mental State Examination (n,=,410) and a diagnostic interview (SCAN; n,=,333), were collected by trained clinicians. Firstly, the items of the GDS-15 were judged on their clinical applicability by three clinical experts. Subsequently, items that were identified as unsuitable were removed using the data of the Assess project (n,=,77), and internal consistency was calculated. Secondly, with respect to criterion validity (sensitivity, specitivity, area under ROC and positive and negative predictive values), the newly constructed shortened GDS was validated in the AGED data set (n,=,333), using DSM-IV diagnosis for depression as measured by the SCAN as ,gold standard'. Results The eight-item GDS that resulted from stage 1 showed good internal consistency in both the Assess data set (,,=,0.86) and the AGED dataset (,,=,0.80). In the AGED dataset, high sensitivity rates of 96.3% for major depression and 83.0% for minor depression were found, with a specificity rate of 71.7% at a cut-off point of 2/3. Conclusion The GDS-8 has good psychometric properties. Given that the GDS-8 is less burdening for the patient, more comfortable to use and less time consuming, it may be a more feasible screening test for the frail nursing home population.

The Ankylosing Spondylitis Quality of Life Questionnaire: validation in a New Zealand cohort

INTERNATIONAL JOURNAL OF RHEUMATIC DISEASES, Issue 4 2010
Katherine 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.

Distinguishing between task and contextual performance for nurses: development of a job performance scale

JOURNAL OF ADVANCED NURSING, Issue 6 2007
Jaimi H. Greenslade
Abstract Title.,Distinguishing between task and contextual performance for nurses: development of a job performance scale Aim., This paper is a report of a development and validation of a new job performance scale based on an established job performance model. Background., Previous measures of nursing quality are atheoretical and fail to incorporate the complete range of behaviours performed. Thus, an up-to-date measure of job performance is required for assessing nursing quality. Methods., Test construction involved systematic generation of test items using focus groups, a literature review, and an expert review of test items. A pilot study was conducted to determine the multidimensional nature of the taxonomy and its psychometric properties. All data were collected in 2005. Findings., The final version of the nursing performance taxonomy included 41 behaviours across eight dimensions of job performance. Results from preliminary psychometric investigations suggest that the nursing performance scale has good internal consistency, good convergent validity and good criterion validity. Conclusion., The findings give preliminary support for a new job performance scale as a reliable and valid tool for assessing nursing quality. However, further research using a larger sample and nurses from a broader geographical region is required to cross-validate the measure. This scale may be used to guide hospital managers regarding the quality of nursing care within units and to guide future research in the area. [source]


Reliability and Validity of a Steadiness Score

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2005
Daniel O. Clark PhD
Objectives: To determine the internal consistency and construct and predictive validity of three survey questions regarding steadiness in a sample of community-dwelling lower-income older adults. Design: A 6-month prospective cohort study. Setting: Community-based. Participants: Three hundred fifty-seven older adults who completed a baseline and 6-month follow-up interviewer-administered survey. These older adults received care at a single, public health system and were judged by insurance status to be of low income. Measurements: Self-report measures of steadiness while walking and transferring; difficulty in mobility, activities of daily living (ADLs), and instrumental activities of daily living (IADLs); chronic illness; falls; hospitalization; and sociodemographic characteristics. Results: The three steadiness questions showed good internal consistency (0.88); construct validity in Pearson correlations with mobility (0.57), ADL (0.53), and IADL scores (0.41); and predictive validity. With regard to predictive validity, steadiness was predictive of falls, hospitalization, and decline in ADL and IADL function over a subsequent 6-month period. Conclusion: Steadiness questions are a potentially valuable addition to survey research and clinical screening to identify persons with current impairment status and falls and disability risk.

The learning environment of paediatric trainees in New Zealand

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 9 2009
Ralph Pinnock
Aims: To assess the learning environment of New Zealand paediatric trainees, examine the factors influencing the trainee's perceptions of their learning environment and to assess the suitability of using the Postgraduate Hospital Education Environment Measure (PHEEM) in New Zealand. Methods: Paediatric trainees completed the PHEEM questionnaire and returned this anonymously by email. Results: Both basic and advanced trainees' perceptions of the environment were generally positive but significant concerns were identified. There were differences in perceptions of the learning environment between the basic and advanced trainees and between sites with more than six trainees compared with those with six or fewer trainees. The PHEEM is practical to use, showed good internal consistency and was acceptable to trainees. Conclusions: Both basic and advanced trainees perceived the learning environment positively but significant concerns must be addressed. The advanced trainees perceived the overall learning environment and the teaching they receive more positively than basic trainees. Trainees at smaller hospitals perceived that their social supports were better than at larger hospitals. The PHEEM can be used to assess the paediatric training environment in New Zealand. [source]


High Self-Control Predicts Good Adjustment, Less Pathology, Better Grades, and Interpersonal Success

JOURNAL OF PERSONALITY, Issue 2 2004
June P. Tangney
What good is self-control? We incorporated a new measure of individual differences in self-control into two large investigations of a broad spectrum of behaviors. The new scale showed good internal consistency and retest reliability. Higher scores on self-control correlated with a higher grade point average, better adjustment (fewer reports of psychopathology, higher self-esteem), less binge eating and alcohol abuse, better relationships and interpersonal skills, secure attachment, and more optimal emotional responses. Tests for curvilinearity failed to indicate any drawbacks of so-called overcontrol, and the positive effects remained after controlling for social desirability. Low self-control is thus a significant risk factor for a broad range of personal and interpersonal problems. [source]


Measuring nurse attitudes towards deliberate self-harm: the Self-Harm Antipathy Scale (SHAS)

JOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 5 2007
P. PATTERSON phd ba (hons) rmn rgn cert ed
Most mental health nurses engage at some point with clients who harm themselves and these nurses often experience strong negative emotional reactions. Prolonged engagement with relapsing clients can lead to antipathy, and ,malignant alienation'. The study reported here has the aim of developing a brief, robust instrument for assessing nurse attitudes in this area. The Self-Harm Antipathy Scale, developed here on a sample of 153 healthcare professionals, has 30 attitudinal items with six factors. It has acceptable face validity, good internal consistency and some evidence of good test,retest reliability. It discriminates effectively between criterion groups. Overall this is evidence for the complexity of nurses' responses to this client group but such complex attitudes can still be assessed using a relatively brief structured instrument. [source]


Psychometric Properties of the Short Index of Problems as a Measure of Recent Alcohol-Related Problems

ALCOHOLISM, Issue 9 2003
Richard Feinn
Background: The Drinker Inventory of Consequences (DrInC) measures overall consequences of drinking and yields five subscale scores. A short form of the DrInC, the Short Index of Problems (SIP), was developed for use when time does not permit completion of the DrInC. This study investigates the psychometric properties of the SIP. Methods: The study sample consisted of 153 problem drinkers who were participants in a placebo-controlled trial of naltrexone and brief counseling. Results: The SIP showed good internal consistency, good concurrent validity, and adequate stability. Four of the five SIP subscales contributed unique variance beyond general drinking consequences. Conclusions: The SIP is useful for measuring drinking consequences in a sample of problem drinkers, and the subscale scores can be interpreted clinically. Further research on the SIP in other populations is warranted. [source]


The reliability and validity of a matrix to assess the completed reflective personal development plans of general practitioners

MEDICAL EDUCATION, Issue 4 2006
Chris Roberts
Introduction, We wished to determine whether assessors could make reliable and valid judgements about the quality of completed reflective personal development plans (PDPs) for the purpose of accrediting UK general practitioners (GPs) for a postgraduate education allowance using a marking matrix, and secondly, to plan a feasible model of PDP assessment in the context of forthcoming GP appraisal/revalidation that would overcome the main sources of error identified from this study. Methods, Within generalisability theory, a variance components analysis on PDP scores estimated reliability and the effect on them of varying, for example, the number of assessors. We investigated the construct validity of the matrix through its internal consistency and detection of differences in the quality of PDPs. Results, For a single PDP and one assessor, 37.6% of the variance in scores was due to true differences in the quality of the PDP. Between 5 and 7 PDP assessors are needed to achieve summative reliability of greater than 0.8. While increasing the number of judges is important, reliability could also be improved by addressing assessor subjectivity. Construct validity was demonstrated, as the matrix distinguished between good, satisfactory and poor PDPs, and it had good internal consistency. Conclusion, PDP assessment has reasonable summative characteristics for the purpose of assessing GPs' reflective continuing professional development. If doctors could include their PDPs within their revalidation folders as evidence of their reflections on pursuing better clinical performance, we have described a reliable, valid and feasible method of external assessment.

The German version of the chronic urticaria quality-of-life questionnaire: factor analysis, validation, and initial clinical findings

ALLERGY, Issue 6 2009
ynek
Background:, Chronic urticaria (CU) is a common skin disorder that causes a substantial burden on patients' quality-of-life (QoL). The aim of this work was to generate and validate a German version of the Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL) and to provide reference assessments of QoL. Methods:, The Italian CU-Q2oL was translated into German and administered to 157 CU patients. They also completed two well-established general dermatology QoL questionnaires, the Dermatology Life Quality Index (DLQI) and Skindex-29. Factor analysis was used to identify scales of the German CU-Q2oL. Correlation to the DLQI and Skindex-29 was used for validation. Multiple linear regression was used to determine which patient characteristics were associated with which dimensions of QoL. Results:, The factor analysis identified six scales of the German CU-Q2oL: functioning, sleep, itching/embarrassment, mental status, swelling/eating, and limits looks, which accounted for 70% of the data variance. Five of these six scales showed good internal consistency, and another five demonstrated convergent validity. On a percentile scale, they had these median CU-Q2oL scores: 29 functioning, 44 sleep, 50 itching/embarrassment, 50 mental status, 31 swelling/eating, 31 limits looks. Disease severity significantly predicted scores on all scales. Age predicted functioning, sleep, itching/embarrassment, and swelling/eating. Sex predicted itching/embarrassment and limits looks. Conclusion:, This study yielded a robust validation of the German version of the CU-Q2oL. It confirmed previous studies that CU has a clinically meaningful burden on QoL, especially for sleep and mental health, and that women are more severely affected by pruritus. The German CU-Q2oL should be widely adopted in clinical research on the treatment of CU. [source]


The Lille Apathy Rating Scale: Validation of a caregiver-based version

MOVEMENT DISORDERS, Issue 6 2008
Kathy Dujardin PhD
Abstract Apathy is reported in 16.5% to 70% of Parkinson's disease (PD) patients. Our recently developed Lille Apathy Rating Scale (LARS) has been specifically validated for patient-based assessment of apathy in PD. The aim of the present study was to validate a caregiver-based version of the LARS. Sixty consecutive PD patients and their respective caregivers participated in the study. An informant-based version of the LARS (LARS-i) was developed to rate apathy via a caregiver-based structured interview. Apathy was also assessed in a patient-based interview using the LARS and the informant- and clinician-rated versions of the Apathy Evaluation Scale (AES). Cronbach's alpha and standardized alpha coefficients were 0.872 and 0.877, respectively, and the split-half reliability was 0.901 (revealing good internal consistency). The test-retest and inter-rater reliability values were 0.960 and 0.996, respectively. Criterion-related validity (according to an independent, expert diagnosis) was good. Scores on the LARS and the LARS-i were highly correlated. However, apathy was rated significantly more severely by the caregiver than by the patient. This difference was significantly higher for demented than nondemented PD patients. The LARS-i was seen to have excellent psychometric properties and appears to be valid for use in PD with respect to the patient-based LARS and the informant- and clinician-rated versions of the AES. © 2008 Movement Disorder Society [source]


Development of the Chinese language paediatric daily occupation scale in Taiwan

OCCUPATIONAL THERAPY INTERNATIONAL, Issue 1 2010
Jin-ling Lo
Abstract The aim of this study was to describe the development of the paediatric daily occupation scale (PDOS) that was validated with Taiwanese children aged from birth to 72 months. Item,scale correlation coefficient was also used to select items. The psychometric properties of PDOS were examined based on the results of 957 children who participated in the study. The Chinese child development inventory (CCDI) was used as a standard to examine the concurrent validity of PDOS on two different samples. The PDOS, completed by parents, contains 340 items with good internal consistency (Cronbach's , = 0.99), test,retest reliability (r = 0.99) and concurrent validity (r = 0.88 between PDOS and CCDI). The sensitivity of PDOS (83%) in detecting children with developmental problems was much higher than CCDI (33%). Because the PDOS is developed and examined on children from greater Taipei area, when using the PDOS with children from different socio-cultural environments, the results need to be interpreted cautiously. Further research of the PDOS to justify its use as a screening tool for early detecting of children with developmental problems is suggested. Copyright © 2009 John Wiley & Sons, Ltd. [source]


Determination of UVA protection factors using the persistent pigment darkening (PPD) as the end point

PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 6 2000
(Part 1) Calibration of the method
Background/Aims: The accuracy and reliability of any method to assess the UVA protection effectiveness of sunscreens needs to be demonstrated. The aim of the present study was to calibrate the effectiveness of a biological end point (Persistent Pigment Darkening, PPD) to assess UVA photoprotection. Methods: Persistent Pigment Darkening was selected as the end point because its action spectrum extends across the UVA. A broad UVA source was chosen to challenge all UVA wavelengths. Attenuation of UVA was performed with neutral density filters (equally absorbing at all wavelengths). Human subjects were tested with a series of UVA beams attenuated by the neutral density filters. The UVA protection effectiveness of a standard sunscreen was also tested with four panels of volunteers to assess the reproducibility of the method. Results: The attenuation factors of the neutral density filters were found to correspond to the UVA protection factors arrived at with PPD as the end point. The repetitive tests showed a good internal consistency of the method. Conclusions: The calibration procedure proposed shows threshold PPD, used as an end point in a UVA-PF test method, to be a reliable endogenous dosimeter for UVA radiation that enters the skin.

Stigma and Self-Concept Among Adolescents Receiving Mental Health Treatment

AMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 2 2009
Tally Moses PhD
Although studies indicate that adolescents diagnosed with mental disorders are stigmatized by the American public, we know very little about the extent to which stigma is experienced by these youth and its effects on their well-being. This cross-sectional study utilizes interviews with 60 adolescents treated in a wraparound program to examine: (a) the extent to which adolescents diagnosed and treated for psychiatric disorders experience mental illness stigma and cope by using secrecy, (b) the extent to which stigmatization is associated with self-concept (self-esteem, mastery, future outlook) and morale (depression), and (c) which clinical and demographic characteristics are associated with perceived stigma. A secondary purpose was to explore the usefulness with adolescents of stigma measures created and adapted primarily from Link's adult stigma scales (Link et al., 1991, 1997). The results support both optimistic and pessimistic interpretations regarding stigma and its effects on adolescents diagnosed and treated for mental disorders. The scales developed for this study demonstrate good internal consistency and construct validity and show promise as tools for further research on stigma as experienced by youth. [source]


Measuring social activities and social function in long-term cancer survivors who received hematopoietic stem cell transplantation

PSYCHO-ONCOLOGY, Issue 5 2010
Karen L. Syrjala
Abstract Objective: Cancer survivors report deficits in social functioning even years after completing treatment. Commonly used measures of social functioning provide incomplete understanding of survivors' social behavior. This study describes social activities of survivors and evaluates the psychometric properties of the Social Activity Log (SAL) in a cohort of long-term survivors of hematopoietic stem cell transplantation (HSCT) for cancer. Methods: One hundred and two (5,20 year) survivors completed the SAL, Short-Form-36 Health Survey (SF-36), and other patient-reported outcomes. Principal components analysis determined the factor structure of the SAL along with correlations and regressions to establish validity. Results: Principal component analysis yielded three factors in the SAL: ,non-contact events' (e.g. telephone calls), ,regular events' (e.g. played cards), and ,special events' (e.g. concerts), which explained 59% of the total variance. The SAL possessed good internal consistency (Cronbach's ,=0.82). SF-36 social function and SAL were moderately correlated (r=0.31). In linear regressions, physical function and depression explained 16% of the variance in the SAL (P<0.001), while physical function, depression, and fatigue predicted 55% of the variance in SF-36 social function (P<0.001). Conclusions: Results support the use of the SAL as a measure of social activity in cancer survivors who received HSCT. Although the SAL is designed to measure social behaviors, SF-36 social function assesses subjective experience and is more strongly associated with depression and fatigue. The SAL appears to be a promising tool to understand the behavioral social deficits reported by long-term survivors of cancer. Copyright © 2009 John Wiley & Sons, Ltd. [source]


Family caregivers' perceptions of hospital-based allied health services post-stroke: Use of the Measure of Processes of Care to investigate processes of care

AUSTRALIAN OCCUPATIONAL THERAPY JOURNAL, Issue 3 2010
Annette Lovat
Aim:,To investigate family caregiver perceptions of allied health professional processes of care and support in hospital following stroke, and to test an adapted version of the Measure of Processes of Care (MPOC) for its suitability of use in the stroke care setting. Methods:,The first stage involved the adaptation and refinement of the MPOC, designed to measure caregiver perceptions of processes of professional care and support across five care dimensions. The second stage involved mailing out of questionnaires to primary caregivers of stroke survivors. A total of 107 completed questionnaires were included in the analysis. The reliability of the adapted questionnaire was assessed and summary statistics were computed. Results:,The reliability of the adapted MPOC was found to be high, with good internal consistency of items within each subscale. Mean scores indicated that caregivers were most likely to report negative perceptions of the way allied health professionals engaged with and supported them, particularly in the area of information provision. Conclusion:,The number of families being affected by stroke is predicted to rise substantially in the near future. Allied health professionals have a significant role to play in supporting family caregivers. Results highlight caregiver-identified areas of weakness in current clinical practice. [source]


Assessment of male sexual function by the Brief Sexual Function Inventory

ARNSTEIN MYKLETUN
OBJECTIVE To present normative data from Norway using the Brief Male Sexual Function Inventory (BSFI, the first patient self-administered questionnaire to assess male sexuality, and used in the USA) in men aged 20,79 years, examine the psychometric properties of the BSFI, explore the impact of sexual function and other variables on overall sexual satisfaction, and compare American and Norwegian normative data. SUBJECTS AND METHODS From public official address lists 3500 men aged 20,79 years were invited to take part in an anonymous questionnaire study, including the BSFI. Altogether 1185 (34%) responded, and the response rates varied with age. RESULTS There was increasingly reduced sexual function concerning drive, erection, ejaculation, and problem assessment with age, and most of the age-effect started at >50 years old. Overall sexual satisfaction followed the same trend, but with a weaker association with age. Analyses of factor structure and internal consistency of the BSFI supported a one-factor solution with good internal consistency. Drive, erection, ejaculation, and problem assessment explained 28% of the variance in overall sexual satisfaction. Being younger and having a sexual partner were also associated with high scores of overall sexual satisfaction. American and Norwegian normative data in the BSFI dimensions were markedly similar. CONCLUSION The BSFI is a short and discrete screening tool for sexual function, and for most clinical and research purposes we recommend using the BSFI as a one-dimensional scale. [source]


Development of a Brief Waiting Room Observation for Behaviours Typical of Reactive Attachment Disorder

CHILD AND ADOLESCENT MENTAL HEALTH, Issue 2 2010
Alexis McLaughlin
Objective:, To develop a brief standardised observational schedule for Reactive Attachment Disorder (RAD) in school-age children to aid clinician recognition of these behaviours. Design:, A new structured observational schedule for symptoms of RAD was developed using unstructured observation of children in a clinic waiting room setting. The measure's ability to discriminate between a sample of children with RAD and a normative sample was established by comparing scores in these two groups. Method:, Children aged 5,8 years (n = 77 [38 RAD cases and 39 controls]) were observed with their primary caregiver in a standardised waiting room setting. A structured observational tool was developed that tested the reliability, sensitivity and specificity of each item. Results:, The schedule has good internal consistency (0.75). The individual items on the observational schedule were predominantly highly discriminatory between cases and comparisons, showing both reasonable sensitivity and excellent specificity. Certain questions were dropped due to poor discrimination and/or poor inter-rater reliability. Conclusion:, The 10-item observational schedule for RAD in school-age children provides a promising tool for assessment, although further research will be required to evaluate its ability to discriminate between RAD and other disorders.
