Test Retest Reliability

Background Adequate muscle strength, power, and endurance are important in children's daily activities and sports. Various instruments have been developed for the assessment of muscle function; each measures different aspects. The Functional Strength Measurement (FSM) was developed to measure performance in activities in which strength is required. Objective The study objective was to establish the test-retest reliability and structural and construct validity of the FSM. Design A cross-sectional descriptive study was conducted. Methods The performance of 474 children with typical development on the FSM was examined. Test-retest reliability (n=47) was calculated with the intraclass correlation coefficient (2.1A) for agreement. Structural validity was examined with exploratory factor analysis, and internal consistency was established with the Cronbach alpha. Construct validity was determined by calculating correlations between FSM scores and scores obtained with a handheld dynamometer (HHD) (n=252) (convergent validity) and between FSM scores and scores on the Movement Assessment Battery for Children–2 (MABC-2) (n=77) (discriminant validity). Results The test-retest reliability of the FSM total score ranged from .91 to .94. The structural validity revealed one dimension, containing all 8 FSM items. The Cronbach alpha was .74. The convergent validity with the HHD ranged from .42 to .74. The discriminant validity with MABC-2 items revealed correlations that were generally lower than .39, and most of the correlations were not significant. Exploratory factor analysis of a combined data set (FSM, HHD, and MABC-2; n=77) revealed 2 factors: muscle strength/power and muscle endurance with an agility component. Limitations Discriminant validity was measured only in children aged 4 to 6 years. Conclusions The FSM, a norm-referenced test for measuring functional strength in children aged 4 to 10 years, has good test-retest reliability and good construct validity.

Background: Although Perceived Stress Scale (PSS, Cohen, Kamarack, Mermelstein, 1983) has been validated and widely used in many domains, there is still no validation in sports by comparing athletes and non-athletes and examining related psychometric indices. Purpose: The purpose of this study was to examine the measurement invariance of PSS between athletes and non-athletes, and examine construct validity and reliability in the sports contexts. Methods: Study 1 sampled 359 college student-athletes (males = 233; females = 126) and 242 non-athletes (males=124; females=118) and examined factorial structure, measurement invariance and internal consistency. Study 2 sampled 196 student-athletes (males = 139, females = 57, Mage =19.88 yrs, SD = 1.35) and examined discriminant validity and convergent validity of PSS. Study 3 sampled 37 student-athletes to assess test-retest reliability of PSS. Results: Results found that 2-factor PSS-10 fitted the model the best and had appropriate reliability. Also, there was a measurement invariance between athletes and non-athletes; and PSS positively correlated with athletic burnout and life stress but negatively correlated with coping efficacy provided evidence of discriminant validity and convergent validity. Further, the test-retest reliability for PSS subscales was significant (r=.66 and r=.50). Discussion: It is suggested that 2-factor PSS-10 can be a useful tool in assessing perceived stress either in sports or non-sports settings. We suggest future study may use 2-factor PSS-10 in examining the effects of stress on the athletic injury, burnout, and psychiatry disorders.

Abstract Background Outcome measurement is an essential part of the evaluation of palliative care and the measurements need to be reliable, valid and adapted to the culture in which they are used. The Integrated Palliative Outcome Scale (IPOS) is a widely used tool for assessing outcomes in palliative care. The aim of this study was to provide Czech version of IPOS and asses its psychometric properties.Methods Patients receiving palliative care in hospice or hospitals completed IPOS and part of the sample also completed Edmonton Symptom Assessment System (ESAS) and Palliative Performance Scale (PPS). The reliability of Czech IPOS was tested with Cronbach alpha (internal consistency) and Intraclass correlation coefficient and Weighted Kappa (test-retest reliability). Construct validity was assessed with factor analysis (Exploratory Factor Analysis) and convergent validity was tested with correlation analysis (Spearman correlation).Results Sample consisted of 140 patients (mean age 72; 90 women; 81% oncologic disease). IPOS internal consistency was 0.789; ICC= 0.88. To study convergent validity, we assessed the correlations of IPOS with ESAS (R= 0.4) and PPS (R= -0.2), however, these results have to be considered preliminary due to the small sample size. Exploratory factor analysis revealed a 2-factor solution on our data. The first factor covers emotional and information needs and the second factor covers physical symptoms.Conclusion Czech IPOS has very good reliability regarding both internal consistency and test-retest reliability. Together with an item analysis results, we can conclude that the Czech adaptation of the tool was successful. The convergent validity needs to be assessed on the larger sample and the proposed 2-factor internal structure of the questionnaire has to be confirmed by using CFA.

OBJECTIVE: To translate, culturally adapt, and validate the psychometric characteristics of the Italian version of the Dance Functional Outcome Survey (DFOS-IT) in adult dancers. DESIGN: Clinical measurement study. METHODS: The DFOS-IT was forward translated, reconciled, backward translated, and reviewed by an expert committee to establish optimal correspondence with the original English DFOS. We examined test-retest reliability in 58 dancers within a 10-day period, using intraclass correlation coefficients (ICC2,1). In a sample of 265 healthy and injured dancers, the following were examined: 1) construct validity, comparing the DFOS-IT to SF-36 using Pearson correlations; 2) exploratory factor analysis and internal consistency; and 3) sensitivity, by generating receiver operating characteristic curves and determining area under the curve (AUC). In a subgroup of 44 dancers, we determined internal responsiveness across three time-points using repeated measures ANOVA (p<0.05). Injured dancers’ scores were analyzed for floor and ceiling effects. RESULTS: The DFOS-IT demonstrated very high test-retest reliability (ICC=0.98). Single-factor loading in exploratory factor analysis supported unidimensionality of the scale, with high internal consistency (a=0.93). DFOS-IT total, activities of daily living (ADL), and Dance Technique scores had strong construct validity compared with scores on the SF-36 PCS (r=0.71). There was excellent sensitivity, with high AUC values (AUC=0.80). There were significant differences across time for DFOS-IT scores (p<0.001), demonstrating responsiveness to change, and no floor or ceiling effects. CONCLUSION: The DFOS-IT is a valid, reliable, and responsive tool that can be used as an outcome and screening measure for Italian adult ballet and modern dancers following lower extremity or low back injury.

Abstract Objective The 25-item Emotional Processing Scale (EPS) is a measure of emotional processing. There is a scarcity of research about its factor structure, test-retest reliability, and validity in individuals with psychiatric symptoms. Method We administered the EPS-25 to a sample (N=512) of people with elevated psychiatric symptoms, using confirmatory factor analysis to evaluate three a priori models from previous research. We then evaluated discriminant and convergent validity against measures of alexithymia (Toronto Alexithymia Scale-20; TAS-20), depressive symptoms (Patient Health Questionaire-9; PHQ-9) and anxiety symptoms (Generalized Anxiety Disorder-7; GAD-7). Results None of the a priori models achieved acceptable fit, and subsequent exploratory factor analysis did not lead to a convincing factor solution for the 25 items. A 5-factor model did, however, achieve acceptable fit if we retained only 15 items (EPS-15) and this solution could be replicated in a holdout sample. Convergent and discriminant validity for EPS-15 was r=-.19-.46 vs. TAS-20, r=.07-.25 vs. PHQ-9, r=.29-.57 vs. GAD-7. Test-retest reliability was ICC=.73. Conclusions This study strengthens the case for the reliability and validity of the five factor Emotional Processing Scale but suggest that only 15 items should be retained. Future studies should further examine the reliability and validity of the EPS-15.

Abstract Background Critical thinking disposition helps medical students and professionals overcome the effects of personal values and beliefs when exercising clinical judgment. The lack of effective instruments to measure critical thinking disposition in medical students has become an obstacle for training and evaluating students in undergraduate programs in China. The aim of this study was to evaluate the psychometric properties of the CTDA test. Methods A total of 278 students participated in this study and responded to the CTDA test. Cronbach’s α coefficient, internal consistency, test-retest reliability, floor effects and ceiling effects were measured to assess the reliability of the questionnaire. Construct validity of the pre-specified three-domain structure of the CTDA was evaluated by explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). The convergent validity and discriminant validity were also analyzed. Results Cronbach’s alpha coefficient for the entire questionnaire was calculated to be 0.92, all of the domains showed acceptable internal consistency (0.81–0.86), and the test-retest reliability indicated acceptable intra-class correlation coefficients (ICCs) (0.93, p < 0.01). The EFA and the CFA demonstrated that the three-domain model fitted the data adequately. The test showed satisfactory convergent and discriminant validity. Conclusions The CTDA is a reliable and valid questionnaire to evaluate the disposition of medical students towards critical thinking in China and can reasonably be applied in critical thinking programs and medical education research.

Abstract Background and aim Growing attention is being given to utilising physical function measures to better understand and manage knee osteoarthritis (OA). The Fremantle Knee Awareness Questionnaire (FreKAQ), a self-reported measure of body-perception specific to the knee, has never been validated in Italian patients. The aims of this study were to culturally adapt and validate the Italian version of the FreKAQ (FreKAQ-I), to allow for its use with Italian-speaking patients with painful knee OA. Methods The FreKAQ-I was developed by means of forward–backward translation, a final review by an expert committee and a test of the pre-final version to evaluate its comprehensibility. The psychometric testing included: internal structural validity by Rasch analysis; construct validity by assessing hypotheses of FreKAQ correlations with the knee injury and osteoarthritis outcome score (KOOS), a pain intensity numerical rating scale (PI-NRS), the pain catastrophising scale (PCS), and the Hospital anxiety and depression score (HADS) (Pearson’s correlations); known-group validity by evaluating the ability of FreKAQ scores to discriminate between two groups of participants with different clinical profiles (Mann–Whitney U test); reliability by internal consistency (Cronbach’s alpha) and test–retest reliability (intraclass correlation coefficient, ICC2.1); and measurement error by calculating the minimum detectable change (MDC). Results It took one month to develop a consensus-based version of the FreKAQ-I. The questionnaire was administered to 102 subjects with painful knee OA and was well accepted. Internal structural validity confirmed the substantial unidimensionality of the FreKAQ-I: variance explained was 53.3%, the unexplained variance in the first contrast showed an eigenvalue of 1.8, and no local dependence was detected. Construct validity was good as all of the hypotheses were met; correlations: KOOS (rho = 0.38–0.51), PI-NRS (rho = 0.35–0.37), PCS (rho = 0.47) and HADS (Anxiety rho = 0.36; Depression rho = 0.43). Regarding known-groups validity, FreKAQ scores were significantly different between groups of participants demonstrating high and low levels of pain intensity, pain catastrophising, anxiety, depression and the four KOOS subscales (p ≤ 0.004). Internal consistency was acceptable (α = 0.74) and test–retest reliability was excellent (ICC = 0.92, CI 0.87–0.94). The MDC95 was 5.22 scale points. Conclusion The FreKAQ-I is unidimensional, reliable and valid in Italian patients with painful knee OA. Its use is recommended for clinical and research purposes.
