Kinds of Psychometric Properties Selected AbstractsPsychometric Properties of IRT Proficiency EstimatesEDUCATIONAL MEASUREMENT: ISSUES AND PRACTICE, Issue 3 2010Michael J. Kolen Psychometric properties of item response theory proficiency estimates are considered in this paper. Proficiency estimators based on summed scores and pattern scores include non-Bayes maximum likelihood and test characteristic curve estimators and Bayesian estimators. The psychometric properties investigated include reliability, conditional standard errors of measurement, and score distributions. Four real-data examples include (a) effects of choice of estimator on score distributions and percent proficient, (b) effects of the prior distribution on score distributions and percent proficient, (c) effects of test length on score distributions and percent proficient, and (d) effects of proficiency estimator on growth-related statistics for a vertical scale. The examples illustrate that the choice of estimator influences score distributions and the assignment of examinee to proficiency levels. In particular, for the examples studied, the choice of Bayes versus non-Bayes estimators had a more serious practical effect than the choice of summed versus pattern scoring. [source] Psychometric Properties of the Dutch Version of the Hospital-Level Consumer Assessment of Health Plans Survey® InstrumentHEALTH SERVICES RESEARCH, Issue 1 2006Onyebuchi A. Arah Objectives. To assess the reliability and validity of a translated version of the American Hospital-level Consumer Assessment of Health Plans Survey® (H-CAHPS) instrument for use in Dutch health care. Data Sources/Study Setting. Primary survey data from adults aged 18 years or more who were recently discharged from two multispecialty city hospitals in the Netherlands. Study Design. We used forward and backward translation procedures and a panel of experts to adapt the 66-item pilot H-CAHPS into a 70-item Dutch instrument. Descriptive statistics and standard psychometric methods were then used to test the reliability and validity of the new instrument. Data Collection. From late November 2003 to early January 2004, the survey was administered by mail to 1,996 patients discharged within the previous 2 months. Principal Findings. Analyses supported the reliability and validity of the following 7-factor H-CAHPS structure for use in Dutch hospitals: on doctor's communication, nurses' communication, discharge information, communication about medication, pain control, physical environment of hospital, and nursing services. The internal consistency reliability of the scales ranged from 0.60 to 0.88. Items related to "family receiving help when on visit,""hospital staff introducing self," and "admission delays" did not improve the psychometric properties of the new instrument. Conclusions. These findings suggest that the H-CAHPS instrument is reliable and valid for use in the Dutch context. However, more research will be needed to support its equivalence to the United States version, and its use for between-hospital comparisons. [source] Psychometric Properties of the Activities-Specific Balance Confidence Scale and the Survey of Activities and Fear of Falling in Older WomenJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 2 2008Kristine M.C. Talley MS OBJECTIVES: To compare the psychometric properties of the Activities-specific Balance Confidence Scale (ABC) and the Survey of Activities and Fear of Falling in the Elderly (SAFE). DESIGN: Secondary analysis using baseline and 12-week data from a randomized, controlled trial on fall prevention. SETTING: Upper Midwest metropolitan area with assessments conducted in participants' homes. PARTICIPANTS: Population-based sample of 272 noninstitutionalized female Medicare beneficiaries aged 70 and older at risk of falling. MEASUREMENTS: Participants self-administered the ABC, SAFE, Geriatric Depression Scale, and Medical Outcomes Study 36-item Short Form Survey. During a home visit, a nurse practitioner administered the Berg Balance Test and Timed Up and Go, measured gait speed, and asked about falls and chronic illnesses. RESULTS: Baseline internal consistency measured using Cronbach alpha was 0.95 for the ABC and 0.82 for the SAFE. Baseline concurrent validity between the ABC and SAFE measured using a correlation coefficient was ,0.65 (P<.001). ABC and SAFE scores were significantly correlated at baseline with physical performance tests and self-reported health status. The ABC had stronger baseline correlations than the SAFE with most measures. Neither instrument demonstrated responsiveness to change at 12 weeks. CONCLUSION: The ABC and SAFE demonstrated strong internal-consistency reliability and validity when self-administered. The ABC had stronger associations with physical functioning and may be more appropriate for studies focused on improving physical function. Both instruments demonstrated ceiling effects, which may explain the lack of responsiveness to change in relatively nonfrail older women. Instruments sensitive to measuring lower levels of fear of falling are needed to capture the full range of this phenomenon in this population. [source] Psychometric Properties of Scale Scores and Performance Levels for Performance Assessments Using Polytomous IRTJOURNAL OF EDUCATIONAL MEASUREMENT, Issue 2 2000Tianyou Wang With a focus on performance assessments, this paper describes procedures for calculating conditional standard error of measurement (CSEM) and reliability of scale scores and classification consistency of performance levels. Scale scores that are transformations of total raw scores are the focus of these procedures, although other types of raw scores are considered as well. Polytomous IRT models provide the psychometric foundation for the procedures that are described. The procedures are applied using test data from ACT's Work Keys Writing Assessment to demonstrate their usefulness. Two polytomous IRT models were compared, as were two different procedures for calculating scores. One simulation study was done using one of the models to evaluate the accuracy of the proposed procedures. The results suggest that the procedures provide quite stable estimates and have the potential to be useful in a variety of performance assessment situations. [source] A Review of Psychometric Properties of Feeding Assessment Tools Used in NeonatesJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 3 2008Tsu-Hsin Howe ABSTRACT Objective:, To appraise the psychometric properties of clinical feeding assessment tools used in a neonatal population. Data sources:, PubMed, OvidMedline, CINHAL, and PsycINFO databases from 1980 to 2007. Reference lists of all identified articles were also reviewed. Study selection:, Research reports written in English that utilized or validated clinical feeding assessment tools. Data extraction:, In total, 941 articles were reviewed. Seven neonatal clinical feeding assessment tools were identified and categorized into three groups: tools used for assessing either bottle-feeding or breastfeeding behaviors, tools used only for assessing bottle-feeding behaviors, and tools used only for assessing breastfeeding behaviors. Results:, The psychometric properties of none of the seven assessment tools identified were satisfactory, and the limited representativeness of the samples of the psychometric research was noted in all assessment tools identified. The Neonatal Oral-Motor Assessment Scale appeared to have been examined more thoroughly and showed more consistent results in psychometric properties than the others, despite its own limitations. Conclusions:, A psychometrically sound neonate feeding assessment tool has not yet been empirically validated. Clinicians who use these tools for clinical and research purposes should take into account this lack of evidence of psychometric soundness and interpret results of assessment with precautions. Well-designed research is needed to study the scientific integrity of these instruments for program evaluations in neonatal care. [source] Development and Psychometric Properties of an Assessment for Persons With Intellectual Disability,The interRAI IDJOURNAL OF POLICY AND PRACTICE IN INTELLECTUAL DISABILITIES, Issue 1 2007Lynn Martin Abstract, This paper describes the development of the interRAI-Intellectual Disability (interRAI ID), a comprehensive instrument that assesses all key domains of interest to service providers relative to a person with an intellectual disability (ID). The authors report on the reliability and validity of embedded scales for cognition, self-care, aggression, and depression. Four provider agencies volunteered to participate and assessed a total of 160 community-dwelling adults with ID using the interRAI ID, Dementia Questionnaire for Persons with Mental Retardation, and Reiss Screen for Maladaptive Behavior. All scales had acceptable levels of internal consistency (Cronbach's alpha 0.74,0.93) and good relationships with the criterion measures (r = 0.50,0.93, p < 0.0001). The development of the interRAI ID represents an important and successful first step toward an integrated, comprehensive, and standardized assessment of adults with ID. Use of this instrument may lead to more appropriate support planning, enhanced communication between various professionals supporting persons with ID, and a more seamless approach to supports across the health and social service systems. [source] Psychometric Properties of the Short Index of Problems as a Measure of Recent Alcohol-Related ProblemsALCOHOLISM, Issue 9 2003Richard 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] Psychometric Properties of the Brazilian Version of the Drug Use Screening InventoryALCOHOLISM, Issue 10 2002Denise De Micheli Background Adolescent involvement with alcohol and other drugs is rising in Brazil, and there is an increasing need for psychometrically sound assessment tools to detect early drug involvement. Methods The psychometric properties of the Brazilian version of the Drug Use Screening Inventory (DUSI) were examined in a sample composed of 71 non,drug-dependent adolescents and 142 adolescents who met DSM-III-R criteria for drug dependence. Results With a cutoff score of 13% or lower for the absolute density index of the substance use area, DUSI correctly classified 80% of the drug-dependent adolescents and 90% of the non,drug-dependent adolescents, thus correctly classifying 83.6% of the sample. Factor analysis applied to each of the 10 DUSI areas indicated their unidimensionality, with substantial percentages of variance on the first factor. The Brazilian version of DUSI presented strong internal consistency reliability for the whole sample (drug-dependents and non,drug-dependent adolescents) with an average across all 10 scales for Cronbach's , reliability coefficient of 0.96 (standard deviation = 0.02) and for the split-half reliability coefficient of 0.88 (standard deviation = 0.08). Conclusions These results suggest that the Brazilian version of DUSI preserves its original psychometric properties and is a sensitive and useful screening instrument for drug use.

[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] Psychometric Properties of Commonly Used Low Back Disability Questionnaires: Are They Useful for Older Adults with Low Back Pain?PAIN MEDICINE, Issue 1 2009Gregory E. Hicks PT ABSTRACT Objectives., To evaluate the psychometric properties of two commonly used low back pain (LBP) disability questionnaires in a sample solely comprising community-dwelling older adults. Design., Single-group repeated measures design. Setting., Four continuing care retirement communities in Maryland and in Virginia. Participants., Convenience sample of 107 community-dwelling men and women (71.9%) aged 62 years or older with current LBP. Outcome Measures., All participants completed modified Oswestry Disability (mOSW) and Quebec Back Pain Disability (QUE) questionnaires, as well as the Medical Outcomes Survey Short-Form 36 questionnaire at baseline. At follow-up, 56 participants completed the mOSW and the QUE for reliability assessment. Results., Test,retest reliability of the mOSW and QUE were excellent with intraclass correlation coefficients of 0.92 (95% confidence interval [CI]: 0.86, 0.95) and 0.94 (95% CI: 0.90, 0.97), respectively. Participants with high pain severity and high levels of functional limitation had higher scores on the mOSW (P < 0.0001) and QUE (P < 0.001) scales than other participants, which represents good construct validity for both scales. The threshold for minimum detectable change is 10.66 points for the mOSW and 11.04 points for the QUE. Both questionnaires had sufficient scale width to accurately measure changes in patient status. Conclusions., It appears that both questionnaires have excellent test,retest reliability and good construct validity when used to evaluate LBP-related disability for older adults with varying degrees of LBP. Neither questionnaire appears to have superior psychometric properties; therefore, both the Oswestry and Quebec can be recommended for use among geriatric patients with LBP. [source] Assessing Negative Consequences in Patients with Substance Use and Bipolar Disorders: Psychometric Properties of the Short Inventory of Problems (SIP)THE AMERICAN JOURNAL ON ADDICTIONS, Issue 6 2007Rachel E. Bender BA The Short Inventory of Problems (SIP), a questionnaire that measures negative consequences of alcohol use, has not been validated among substance users with co-occurring psychiatric illness. This study examined the psychometric properties of the SIP in 57 outpatients diagnosed with substance use disorder and bipolar disorder. We modified the items to assess drugs in addition to alcohol and, further, we added corresponding items to assess consequences of bipolar disorder. This modified version of the SIP was psychometrically sound, and may be useful in patients with both disorders. A greater understanding of perceived negative consequences may enhance outcome assessment in dually diagnosed populations. [source] Psychometric Properties of the Mentor Role Instrument when Used in an Academic Medicine SettingCLINICAL AND TRANSLATIONAL SCIENCE, Issue 3 2010Terri Collin Dilmore Ph.D. Abstract The Ragins and McFarlin Mentor Role Instrument (RMMRI) was originally developed to measure perceptions of mentoring relationships in research and development organizations. The current study was designed to evaluate the RMMRI's reliability and validity when the instrument was administered to clinical and translational science trainees at an academic medical center. The 33-item RMMRI was administered prospectively to a cohort of 141 trainees at the University of Pittsburgh in 2007,2008. Likert-scale items focused on perceptions of five mentoring roles in the career dimension (sponsor, coach, protector, challenger, and promoter) and six mentoring roles in the psychosocial dimension (friend, social associate, parent, role model, counselor, and acceptor). Outcome items included overall perceptions of mentoring satisfaction and effectiveness. Of 141 trainees, 53% were male, 66% were white, 22% were Asian, and 59% were medical doctors. Mean age was 32 years. Analyses showed strong within-factor inter-item correlations (Pearson Coefficients of 0.57,0.93); strong internal consistency (Cronbach alphas of 0.82,0.97); confirmatory factorial validity, as demonstrated by confirmatory factor analysis of the two mentoring dimensions, 11 mentoring roles, and 33 RMMRI items; and concurrent validity, as demonstrated by strong correlations (Pearson Coefficients of 0.56,0.71) between mentoring dimensions, satisfaction, and effectiveness. This article concludes that the RMMRI shows reliability and validity in capturing the multidimensional nature of mentoring when administered to clinical and translational science trainees in the academic setting.

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] Psychometric properties of the Trauma Assessment for AdultsDEPRESSION AND ANXIETY, Issue 2 2009Matt J. Gray Ph.D. Abstract Background: The Trauma Assessment for Adults (TAA) was developed to facilitate the assessment of exposure to traumatic events that could result in posttraumatic stress disorder (PTSD). The TAA inquires about numerous potentially traumatic events that an individual may have experienced. Although the TAA has been used extensively for clinical and research purposes, its psychometric properties have never been formally evaluated. The objective of the present investigation was to evaluate the psychometric properties of this frequently used measure. Methods: The studies reported here describe the performance of the TAA in two samples,college undergraduates (N=142) and community mental health center clients (N=67). Among undergraduates, 1-week temporal stability was evaluated and, in both samples, item- and scale-level convergence of the TAA with an established trauma exposure measure was assessed. Convergence of the TAA with clinically related constructs was also evaluated. Results: The TAA exhibited adequate temporal stability (r=.80) and satisfactory item-level convergence with existing measures of trauma history among college students. In the clinical sample, the TAA again converged well with an established measure of trauma exposure (r=.65). It was not as strongly predictive, in either sample, of trauma-related distress relative to an alternate trauma exposure measure. Conclusion: Although it performs satisfactorily, the TAA does not appear to be superior to other existing measures of trauma exposure. Depression and Anxiety, 2009. © 2008 Wiley-Liss, Inc. [source] Psychometric properties of the Pediatric Motor Activity Log used for children with cerebral palsyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 3 2009MARGARET WALLEN MA BAPPSC(OT) The Pediatric Motor Activity Log (PMAL) is a parent-report measure of the use, by children with hemiplegic cerebral palsy (CP), of their affected upper limb in everyday activities. The aim of this study was to examine the psychometric properties of both scales of the PMAL (,How Often' and ,How Well' scales) using Rasch measurement modelling. Sixty-one parents of children with hemiplegic CP completed the PMAL and 31 completed it again 3 weeks later. The mean age of children was 4 years 6 months (SD 1y 9mo); 35 males, 26 females. Children were at Gross Motor Function Classification System (GMFCS) levels I (83%) and II (17%), and Manual Ability Classification System levels I (35%), II (52%), and III (14%). The original scales were found to have disordered rating scale structure. Further Rasch modelling with collapsed rating scale structures resulted in both scales conforming to the expectations of the Rasch model, yielding strong evidence for construct validity and reliability. One item from the How Often scale failed to conform to Rasch expectations and was deleted in subsequent analyses. Test,retest reliability of both scales was high (the intraclass correlation coefficient for the How Often scale was 0.94, and for the How Well scale 0.93). The revised scales possess good psychometric properties, specifically a logical item hierarchy, evidence of unidimensionality, adequate rating scale structure, and good test,retest reliability. We conclude that the revised PMAL has the capacity to yield valid and reliable scores except for children at the extremes of upper limb ability.

In particular, for the examples studied, the choice of Bayes versus non-Bayes estimators had a more serious practical effect than the choice of summed versus pattern scoring. [source] Psychometric properties of the Attitudes Towards Body Figure Questionnaire in Mexican female students and patients with eating disordersEUROPEAN EATING DISORDERS REVIEW, Issue 6 2006Claudia Unikel Santoncini Abstract The aim of this article was to determine the psychometric characteristics of the Attitudes Towards Body Figure Questionnaire in a sample of Mexican female students and to compare them with a sample of patients with eating disorders. A self-applicable questionnaire with 15 questions on the importance of one's weight, and figure was given to a sample of students with an average age of 18 years in Mexico City (N,=,408) and a sample of patients under treatment (N,=,87). The results showed adequate values of internal consistency and a factorial structure in two highly correlated factors that was corroborated in a confirmatory factorial analysis. The questionnaire yielded data with adequate concurrent and predictive validity as well as appropriate values of sensitivity and specificity. This questionnaire constitutes a significant contribution to the field of research on eating disorders and body image in adolescents in Mexico that is why its use is recommended for research and prevention work in the area.

[source] Revising the Cannabis Use Disorders Identification Test (CUDIT) by means of Item Response TheoryINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 3 2010Beatrice Annaheim Abstract Cannabis use among adolescents and young adults has become a major public health challenge. Several European countries are currently developing short screening instruments to identify ,problematic' forms of cannabis use in general population surveys. One such instrument is the Cannabis Use Disorders Identification Test (CUDIT), a 10-item questionnaire based on the Alcohol Use Disorders Identification Test. Previous research found that some CUDIT items did not perform well psychometrically. In the interests of improving the psychometric properties of the CUDIT, this study replaces the poorly performing items with new items that specifically address cannabis use. Analyses are based on a sub-sample of 558 recent cannabis users from a representative population sample of 5722 individuals (aged 13,32) who were surveyed in the 2007 Swiss Cannabis Monitoring Study. Four new items were added to the original CUDIT. Psychometric properties of all 14 items, as well as the dimensionality of the supplemented CUDIT were then examined using Item Response Theory. Results indicate the unidimensionality of CUDIT and an improvement in its psychometric performance when three original items (usual hours being stoned; injuries; guilt) are replaced by new ones (motives for using cannabis; missing out leisure time activities; difficulties at work/school). However, improvements were limited to cannabis users with a high problem score. For epidemiological purposes, any further revision of CUDIT should therefore include a greater number of ,easier' items. Copyright © 2010 John Wiley & Sons, Ltd. [source] Psychometric properties of an interviewer-administered version of the Kessler Psychological Distress scale (K10) among Dutch, Moroccan and Turkish respondentsINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 3 2009T. Fassaert Abstract The Kessler Psychological Distress scale (K10) is an instrument that is widely used to screen for mental disorders, but information is lacking on its psychometric qualities in non-Western samples. This study used a population-based sample (N = 725) to assess the reliability and validity of the K10 across ethnic groups in an urban area. The results were generally supportive of the K10 as a reliable and valid instrument to screen for anxiety and depression in all three groups. Cronbach's alpha was high (0.93) and the results indicated the existence of a solid single factor structure. Item bias in relation to ethnic background was minor. In each group, there was good criterion validity with respect to one-month DSM-IV diagnosis for depressive and/or anxiety disorder. The results nevertheless highlight the importance of cross-cultural validation, as we found different cut-off values for ethnic subgroups to obtain optimal sensitivity and specificity for detecting depressive and/or anxiety disorders.

[source] Psychometric properties of the Retrospective Self Report of Inhibition (RSRI) in a representative German sampleINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 2 2008Heike Rohrbacher Abstract The present study examined the internal consistency, factorial structure, and construct validity of the German version of the Retrospective Self Report of Inhibition (RSRI), a questionnaire measure of behavioral inhibition. The research was based on data from a German prospective-longitudinal community study of 3021 adolescents and young adults (aged 14,24 years at baseline). Diagnostic assessment was based on the DSM-IV/M-CIDI and general psychopathological distress was assessed with SCL-90-R. Results of confirmatory factor analysis indicated adequate fit of the two-factor model, suggested by the authors of the original version. Indices of internal consistency of the RSRI and its subscales ,social/school' and ,fear/illness' were shown to be sufficient for the total sample and even higher in subgroups of subjects with certain DSM-IV diagnoses. Associations with variables such as mental distress, parental psychopathology, and DSM-IV disorders were in line with theoretical assumptions and confirm different aspects of the validity (convergent, concurrent, predictive) of the instrument. The psychometric properties of the German RSRI were found to be comparable to those of the English version. The applicability of this questionnaire in German-speaking countries is therefore recommended for adolescents and young adults. Copyright © 2008 John Wiley & Sons, Ltd. [source] Psychometric properties of the Chinese version of the Swanson, Nolan, and Pelham, version IV scale , parent formINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 1 2008Susan Shur-Fen Gau Abstract This study aimed to establish the psychometric properties of parent ratings on the Chinese version of the Swanson, Nolan, and Pelham IV scale (SNAP-IV) in a school-based sample of 3534 students in grades 1 to 8 from two cities and two suburbs in Taiwan and 189 children diagnosed with attention deficit/hyperactivity disorder (ADHD) (aged 6 to 15) consecutively recruited from a medical center in Taipei. Parents completed the Chinese versions of the SNAP-IV, Strengths and Difficulties Questionnaire, and Child Behavior Checklist. The Chinese SNAP-IV demonstrated similar three factor structure (Inattention, Hyperactivity/Impulsivity, and Oppositional) as its English version, and satisfactory test,retest reliability (intraclass correlation = 0.59,0.72), internal consistency (alpha = 0.88,0.90), concurrent validity (Pearson correlations = 0.56,0.72), and discriminant validity. Boys scored higher than girls across the eight school grade levels. The SNAP-IV clearly distinguished children with ADHD from school-based participants. Comorbidity with oppositional defiant disorder/conduct disorder predicted higher SNAP-IV scores among children with ADHD. Our findings suggest that the Chinese SNAP-IV is a reliable and valid instrument for rating ADHD-related symptoms in both clinical and community settings in Taiwan.

[source] Reliability and validity of the Junior Temperament and Character InventoryINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 4 2001Klaus Schmeck Abstract The Junior Temperament and Character Inventory (JTCI) was developed to assess the temperament (,novelty seeking', ,harm avoidance', ,reward dependence', ,persistence') and character (,self-directedness', ,cooperativeness', ,self-transcendence') dimensions of Cloninger's biosocial model of personality in children and adolescents. The psychometric properties of the JTCI are presented. We used the German version of JTCI in a clinical sample of 188 adolescent psychiatric patients (aged 12 to 18 years) and in a non-referred sample of 706 German adolescents of the same age range. Aspects of reliability and validity are discussed. We subjected the JTCI to confirmatory factor analysis and were able to replicate the temperament and character scales of the original TCI. The internal consistency of the scales was satisfactory with the exception of ,reward dependence' and ,persistence'. Construct validity was supported by good correspondence of JTCI dimensions with related constructs. Psychometric properties of the German version of JTCI are very promising. Results yield strong support for Cloninger's psychobiological theory. Copyright © 2001 Whurr Publishers Ltd. [source] Psychometric properties of the Chinese version of the Bipolar Spectrum Diagnostic ScaleJOURNAL OF CLINICAL NURSING, Issue 19-20 2010Hsin Chu Aim and objectives., The aim of this study was to test the psychometric properties of the Chinese version of the Bipolar Spectrum Diagnostic Scale (C-BSDS) in a Chinese population to serve as an aid to clinical diagnosis of bipolar disorders. Background., Bipolar spectrum disorders are often misdiagnosed because of the wide range of symptoms seen in patients. The consequences of delayed diagnoses or misdiagnoses can be devastating. Design., A cross-sectional research design. Method., Two hundred patients with affective disorders from a psychiatric outpatient clinic in Taiwan were enrolled. Internal consistency reliability and two-week test,retest reliability were performed to evaluate the reliability of the C-BSDS. Expert content validity and factor analysis were used for testing construct validity. To evaluate sensitivity and specificity, the Chinese version of the Mini International Neuropsychiatric Interview (MINI) was used as the gold standard for diagnosis. Results., The internal consistency coefficient measured by intra-class correlation (ICC) was 0·81, the test,retest reliability coefficient was 0·85 and the expert validity was 0·85. For construct validity, ,irritable and hyper-energetic factors' and ,depressed and lack of energy factors' were extracted by factor analysis. These two factors reflected the structure of the original scale and accounted for 33·27% of the variance. The optimal cut-off was 12, which yielded a sensitivity of 74 and a specificity of 0·97 for detecting bipolar disorder and for bipolar II disorder these were 0·79 and 0·68, respectively. Conclusions., The C-BSDS showed good reliability and validity, and the results were consistent with the English version of the BSDS. Therefore, the C-BSDS is an effective tool for evaluation of a Chinese population. Relevance to clinical practice., The BSDS can further increase the detection rate of bipolar disorders, especially bipolar II disorder, with satisfactory sensitivity and specificity. It can effectively assist with clinical screening of patients for bipolar spectrum disorders. [source] Psychometric properties of the Brief Life Satisfaction ScalesJOURNAL OF CLINICAL PSYCHOLOGY, Issue 1 2004Bernard Lubin The development, psychometric characteristics, and clinical utility of a brief measure of life satisfaction, the Brief Life Satisfaction Scales (BLSS), are presented. Factor analysis of the 10-item scale yielded three factors: self-satisfaction, interpersonal satisfaction, and social role satisfaction. Reliability (internal consistency and retest) and validity (concurrent, construct, discriminant, known group, predictive, and incremental) were adequate to good. Clinical uses of the BLSS and additional studies are discussed. © 2003 Wiley Periodicals, Inc. J Clin Psychol. [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] Psychometric properties of the MacNew heart disease health-related quality of life instrument in patients with heart failureJOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 4 2008Stefan Höfer Abstract Rationale, aims and objectives, Heart failure (HF) is a severe chronic disease and impairs health-related quality of life (HRQL). While validated specific HRQL instruments are required for evaluation of treatment and rehabilitation in patients with HF, a single validated measure to document changes in HRQL for patients with different heart disease diagnoses would be invaluable. The purpose of this analysis was the psychometric analysis of the German MacNew Heart Disease Questionnaire (MacNew) in HF patients, which has previously been shown to be reliable and valid in patients with myocardial infarction, angina pectoris and arrhythmia. Methods, We recruited 89 patients (61.7 ± 11.5 years; 84.3% male) in two Austrian and one Swiss cardiology department with documented HF (effect sizes 28.9 ± 10.1%). The self-administered MacNew, the Short Form-36 (SF-36) and the Hospital Anxiety and Depression Scale were completed. Internal consistency reliability (Cronbach's ,), discriminative and evaluative validity were assessed. Results, Cronbach's , exceeded 0.80. Each MacNew scale differentiated between patients with and without anxiety (3.9 ± 1.0 vs. 5.3 ± 0.8, all P < 0.001), with and without depression (4.2 ± 1.2 vs. 5.2 ± 0.9 all P < 0.03) and by the SF-36 health transition item (deteriorate = 4.39, no change = 4.95, improve = 5.45, all P < 0.02). Evaluative validity was demonstrated with effect sizes >0.70 for a subsample attending a 12-week outpatient rehabilitation programme. Conclusions, The German language version of the MacNew demonstrates consistently acceptable psychometric properties of reliability, validity and responsiveness in patients with documented HF. Together with previous documentation of reliability, validity and responsive, these findings strengthen the argument for the MacNew as a potential ,core' HRQL measure, at least in the German language. [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 Sleep and Settle Questionnaire for parents of infants: Psychometric propertiesJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 5 2001S Matthey Objective: To determine the psychometric properties of a parent-report questionnaire (Sleep and Settle Questionnaire (SSQ)) assessing: (i) the infant's sleep and settling behaviour, and (ii) the parent's level of concern with such behaviours. Methodology: Test-retest reliability was determined by administering the SSQ to 20 mothers on two occasions, 7,14 days apart. Validity was determined by comparing SSQ responses between mothers with 6-week-old infants who, on a semistructured questionnaire, reported no sleep or settling difficulties (n = 56,60) with those who reported they were experiencing difficulties (n = 133). Further comparison was made with a sample of mothers (n = 34,36) attending a community class on sleep and settling difficulties with infants. Sensitivity to change was determined by comparing mothers' SSQ responses at 6-weeks and 6-months postpartum. Results: The SSQ was found to have low test,retest reliability on items referring to the infants' sleep and settling behaviour, but moderate reliability for the extent that such behaviour bothered the parent. Comparison across the different samples showed good discriminant and concurrent validity. Conclusions: Parental reports on the SSQ indicates that over a short period (1,2 weeks) the infants' sleep and settling behaviour can change considerably, but that the extent to which such behaviour bothers the parent is more stable. Good validity demonstrates the SSQ is sensitive to differing infant behaviour. It is recommended as both a clinical and research instrument, and could be used to complement assessments focusing on the parent's psychosocial adjustment in the early postpartum period. [source] The Alcohol Use Disorders Identification Test: An Update of Research FindingsALCOHOLISM, Issue 2 2007Duane F. Reinert Background: The Alcohol Use Disorders Identification Test (AUDIT) has been extensively researched to determine its capability to accurately and practically screen for alcohol problems. Methods: During the 5 years since our previous review of the literature, a large number of additional studies have been published on the AUDIT, abbreviated versions of it, its psychometric properties, and the applicability of the AUDIT for a diverse array of populations. The current article summarizes new findings and integrates them with results of previous research. It also suggests some issues that we believe are particularly in need of further study. Results: A growing body of research evidence supports the criterion validity of English version of the AUDIT as a screen for alcohol dependence as well as for less severe alcohol problems. Nevertheless, the cut-points for effective detection of hazardous drinking as well as identification of alcohol dependence or harmful use in women need to be lowered from the originally recommended value of 8 points. The AUDIT-C, the most popular short version of the AUDIT consisting solely of its 3 consumption items, is approximately equal in accuracy to the full AUDIT. Psychometric properties of the AUDIT, such as test,retest reliability and internal consistency, are quite favorable. Continued research is urged to establish the psychometric properties of non-English versions of the AUDIT, use of the AUDIT with adolescents and with older adults, and selective inclusion of alcohol biomarkers with the AUDIT in some instances. Conclusions: Research continues to support use of the AUDIT as a means of screening for the spectrum of alcohol use disorders in various settings and with diverse populations.
