Reliability and Validity of the Activity Participation Assessment for School-age Children in Korea

Objective This pilot study examined the internal consistency, test—retest reliability, construct validity, and discriminant validity of the Activity Participation Assessment (APA) for school-age children in Korea. Methods The construct validity of the APA was first established by factor analysis on the response of 134 nondisabled children. Internal consistency was evaluated for each of the factors. A test—retest study was conducted on 22 nondisabled children. Discriminant validity was established by comparing the participation of 56 nondisabled children and 56 children with intellectual disabilities and examining sex differences of 61 boys and 61 girls. Results Analysis of the APA revealed five factors, which were labeled as instrumental activities of daily living (IADL), sports and outdoor activities, hobbies and school activities, social activities, and personal care. The factors showed acceptable levels of internal reliability (Cronbach's alpha = .63–.89). The intraclass correlation coefficient (ICC) for the five factors were all in the good range (ICC = .86–.92). We found statistically significant difference between nondisabled children and children with intellectual disabilities in five factors. We also found that girls participated in significantly more IADL, hobbies and school activities, and social activities. However, boys participated in significantly more sports and outdoor activities. Conclusion The APA shows good internal reliability, test—retest reliability, discriminant validity, and construct validity. However, evidence of psychometric properties was limited by a small sample size. Psychometric properties such as interrater reliability as well as concurrent validity and construct validity need to be tested using a larger sample size with representative demographics.

Background: This article presents the procedure of the elaboration and verification of the first Polish Sense of Team Efficacy Questionnaire (Kwestionariusz Poczucia Druzynowej Skutecznosci – KPDS). Material/Methods: Two research stages involved a total of 373 professional athletes. Based on the collected data, the internal structure and psychometric properties of the instrument were established. Results: As a result of the conducted statistical analyses, a questionnaire was obtained. Analyses confirmed the stability of the internal structure of the questionnaire. The instrument also obtained satisfactory coefficients of reliability (using Cronbach’s alpha internal reliability coefficient) and construct validity. In order to establish the convergent and discriminant validity of the KPDS, the analysis of the multitrait-multimethod matrix was applied, using the Group Environment Questionnaire (GEQ). Predictive validity was established using the result obtained in a match played directly after the conducted study. Conclusions: The obtained results confirmed the relevance of creating the KPDS. The questionnaire was made up of 21 items representing 4 subscales: fitness, preparation, effort and endurance. Calculation of a general score for the KPDS also proved to be possible.

Test Retest Reliability

AbstractThe NIH Toolbox (NIHTB) Pattern Comparison Processing Speed Test was developed to assess processing speed within the NIHTB for the Assessment of Neurological Behavior and Function Cognition Battery (NIHTB-CB). This study highlights validation data collected in adults ages 18–85 on this measure and reports descriptive data, test–retest reliability, construct validity, and preliminary work creating a composite index of processing speed. Results indicated good test–retest reliability. There was also evidence for both convergent and discriminant validity; the Pattern Comparison Processing Speed Test demonstrated moderate significant correlations with other processing speed tests (i.e., WAIS-IV Coding, Symbol Search and Processing Speed Index), small significant correlations with measures of working memory (i.e., WAIS-IV Letter-Number Sequencing and PASAT), and non-significant correlations with a test of vocabulary comprehension (i.e., PPVT-IV). Finally, analyses comparing and combining scores on the NIHTB Pattern Comparison Processing Speed Test with other measures of simple reaction time from the NIHTB-CB indicated that a Processing Speed Composite score performed better than any test examined in isolation. The NIHTB Pattern Comparison Processing Speed Test exhibits several strengths: it is appropriate for use across the lifespan (ages, 3–85 years), it is short and easy to administer, and it has high construct validity.

OBJECTIVE To analyze evidence of the validity and reliability of a Brazilian Portuguese version of the Quality of Care Scale from the perspective of people with physical and intellectual disabilities.METHODS There were 162 people with physical disabilities and 156 with intellectual disabilities from Porto Alegre and metropolitan region, who participated in the study in 2008. Classical psychometrics was used to independently analyze the two samples. Hypotheses for evidence of criterion validity (concurrent type) were tested with the Mann-Whitney test for non-normal distributions. Principal components analysis was used to explore factorial models. Evidence of reliability was calculated with Cronbach alpha for the scales and subscales. Test-retest reliability was analyzed for individuals with intellectual disabilities through intra-class correlation coefficient and the Willcoxon test.RESULTS The principal components in the group with physical disabilities replicated the original model presented as a solution to the international project data. Evidence of discriminant validity and test-retest reliability was found.CONCLUSIONS The transcultural factor model found within the international sample project seems appropriate for the samples investigated in this study, especially the physical disabilities group. Depression, pain, satisfaction with life and disability may play a mediating role in the evaluation of quality of care. Additional research is needed to add to evidence of the validity of the instruments.

Abstract Background Patient enablement is a core tenet of patient-centred and holistic primary care. The Patient Enablement Instrument (PEI) is a transitional measure limited in its ability to measure changes over time. A modified version, PEI-2, has been developed to measure enablement at a given time-point without comparison to a recalled baseline. Objective To assess the validity, reliability, sensitivity and responsiveness of PEI-2. Methods PEI-2 was modified from the Chinese PEI to assess enablement over 4 weeks in a prospective cohort study nested within a community support programme [Trekkers Family Enhancement Scheme (TFES)] in Hong Kong. Construct validity was assessed by factor analysis and convergent validity by Spearman’s correlations with health-related quality of life and depressive symptoms. Internal reliability was assessed using Cronbach’s alpha. Test–retest reliability was assessed by intraclass correlation (ICC), responsiveness by 12–24-month change in PEI-2 score and sensitivity by differences in change of PEI-2 score between TFES participants and a control group. Results PEI-2 demonstrated construct validity with all items loading on one factor (factor loadings >0.7). Convergent validity was confirmed by significant correlations with 12-item Short Form Questionnaire, version 2 (r = 0.1089–0.1919) and Patient Health Questionnaire-9 (r = −0.2030). Internal reliability was high (Cronbach’s alpha = 0.9095) and test–retest reliability moderate (ICC = 0.520, P = 0.506). Significant improvements in PEI-2 scores among the TFES group suggested good responsiveness (P < 0.001). The difference in change of PEI-2 scores between TFES and control was significant (P = 0.008), indicating good sensitivity. Conclusions This study supports the validity, reliability, sensitivity and responsiveness of PEI-2 in measuring changes in enablement, making it a promising tool for evaluating enablement in cohort and intervention studies.

AbstractObjectiveTo validate the general nutrition knowledge questionnaire developed by Parmenter and Wardle (1999) in a Turkish student sample.DesignThe original questionnaire of Parmenter and Wardle (1999) was modified and translated into Turkish. The modified questionnaire was administered to second year undergraduate students. Some students completed the questionnaire twice for the measurement of test–retest reliability. Statistical analysis was performed on the responses to measure the internal reliability, test–retest reliability and construct validity.SettingStudents completed the questionnaire under supervision. The questionnaire was completed at the end of lectures. Retest was carried out two weeks after first administration of the test.SubjectsA total of 195 undergraduate students studying either nutrition and dietetics (n 90) or engineering (n 105) participated in the study. Of these, 125 students completed the questionnaire on two occasions.ResultsOverall internal reliability (Cronbach's α = 0·89) and test–retest reliability (0·86) were high. Significant differences between the scores of the two groups of students indicated that the questionnaire had satisfactory construct validity.ConclusionsThe modified version of the general nutrition knowledge questionnaire can be used as a tool to examine the nutrition knowledge of adults in Turkey. In the next stage of the study, some adjustments need to be made to the items that led to low reliability values so that these items will be more applicable to the eating habits and patterns of Turkish people.

Minimal Evidence

This study investigated construct validity for a “nonverbal” measure of self-esteem, the Sliding Person Test (SPERT). Seven personality measures and an intelligence test were administered to 202 college students. A test-retest reliability coefficient of .82 was obtained ( N = 45). Correlations between scores on SPERT and social desirability, anxiety, and IQ indicated sufficiently low overlap with these variables. Minimal evidence of convergent and discriminant validity was established. Linear and curvilinear relationships between scores for SPERT and social and emotional adjustment, respectively, were contrary to expectations but similar to those of previous studies. Expected differences between students high and low in self-acceptance with large SPERT discrepancies support other literature which suggests that large self-ideal discrepancies are associated with better adjustment and lower anxiety for highly self-accepting people.

Test Retest Reliability

Background There is little evidence for the measurement properties of instruments commonly used for women with pelvic girdle pain. Objective The aim of this study was to examine the internal consistency, test-retest reliability, and construct validity of instruments used for women with pelvic girdle pain. Design This was a cross-sectional methodology study, including test-retest reliability assessment. Methods Women with pelvic girdle pain in pregnancy and after delivery participated in a postal survey that included the Pelvic Girdle Questionnaire (PGQ), Oswestry Disability Index (ODI), Disability Rating Index (DRI), Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), and 8-item version of the Medical Outcomes Study 36-Item Short-Form Health Survey questionnaire (SF-36). Test-retest reliability was assessed with a random subsample 1 week later. Internal consistency was assessed with the Cronbach alpha, and test-retest reliability was assessed with the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). Construct validity based on hypotheses was assessed by correlation analysis. Discriminant validity was assessed with the area under the receiver operating characteristic curve. Results All participants responded to the main (N=87) and test-retest (n=42) surveys. Cronbach alpha values ranged from .88 to .94, and ICCs ranged from .78 to .94. The MDC at the individual level constituted about 7% to 14% of total scores for the 8-item version of the SF-36, ODI, and PGQ activity subscale; about 18% to 22% for the DRI, PGQ symptom subscale, and PCS; and about 25% for the FABQ. Hypotheses were mostly confirmed by correlations between the instruments. The PGQ was the only instrument that significantly discriminated participants who were pregnant from participants who were not pregnant as well as pain locations. Limitations A comparison of responsiveness to change of the various instruments used in this study was not undertaken, but will be carried out in a future study. Conclusions Self-report instruments for assessing health showed good internal consistency, test-retest reliability, and construct validity for women with pelvic girdle pain. The PGQ was the only instrument with satisfactory discriminant validity, thus, it is recommended for evaluating symptoms and disability in patients with pelvic girdle pain.
