Abstract Aims Personal agency is a variable which potentially facilitates personal recovery in people with serious mental illness. This study aimed to develop a new brief measure for subjective personal agency that can be completed by people with serious mental illness. Methods Two focus group interviews were first conducted with 11 people with schizophrenia to understand the fundamental components of subjective personal agency for people with serious mental illness living in the community. One group comprised six people with schizophrenia living in the community, while the other consisted of five people with schizophrenia working as peer-support workers. We then developed scale items through collaboration with people with schizophrenia and qualitative analysis (stage 1). A cross-sectional survey was then conducted to test the psychometric properties of the new scale among service users with schizophrenia in 18 assertive community treatment teams (stage 2). Factor validity was tested via exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). We evaluated convergent validity with the Boston University Empowerment Scale (BUES), divergent validity with the global assessment of functioning (GAF), internal consistency, and test–retest reliability. Results Seven items were included in the scale at stage 1. In stage 2, 195 participants completed this scale. EFA revealed a one-factor model with five items. CFA indicated good model fit (χ2 statistics [CMIN] = 8.445, df = 5 (CMIN/df = 1.689), p = 0.133, comparative fit index = 0.974, Tucker–Lewis fit index = 0.949, root mean square error of approximation = 0.077 and standardised root mean squared residual = 0.042). The new scale was significantly correlated with total BUES score (r = 0.526, p < 0.001), but not with GAF score. Cronbach's α for internal consistency was 0.79, and intra-class correlation coefficient for test–retest reliability was 0.70. Conclusion We developed a new, five-item Subjective Personal Agency scale (SPA-5) that can be completed by people with serious mental illness. Further studies are needed to confirm the results outside Japan.

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.

Introduction: There is a need to have appropriate information about the ability of Parkinson's disease (PD) patients to perform cognitive instrumental activities of daily living (IADL). The purpose of the present study was to assess the psychometric properties of the Persian version of the Penn Parkinson's Daily Activities Questionnaire-15 (PDAQ-15). Methods: A total of 165 knowledgeable informants of PD patients completed the PDAQ-15. The Clinical Dementia Rating Scale, Hoehn and Yahr staging, Hospital Anxiety and Depression Scale (HADS) and Lawton IADL scale were included in the study. Internal consistency and test-retest reliability were evaluated by Cronbach's alpha coefficient and intraclass correlation coefficient (ICC), respectively. To examine the dimensionality of the questionnaire, exploratory factor analysis was used. The construct validity was assessed using Spearman rank correlation test. To assess the discriminative validity, PDAQ-15 scores were compared across cognitive stages. Results: The PDAQ-15 showed strong internal consistency (Cronbach's α = 0.99) and test-retest reliability (ICC= 0.99). Only one dimension identified for the PDAQ-15 in the factor analysis. There was strong correlation between PDAQ-15 with depression domain of HADS scale and Lawton IADL scale. (rs = |0.71–0.95|). The correlation of PDAQ-15 with anxiety domain of HADS scale was moderate (rs = 0.66). Discriminative validity analysis showed that the PDAQ-15 has significant power to discriminate between PD patients across cognitive stages. Conclusion: These results suggest that the PDAQ-15 is a valid and reliable PD-specific instrument that can be useful in clinical and research settings.

Objective: The purposes of this paper were to (a) develop a new short, theory-driven, version of the physical activity enjoyment scale (PACES-S) using content analysis; and (b) subsequently to measure the psychometric properties (construct validity, internal consistency, test–retest reliability, and concurrent validity) of the PACES-S for adolescents. Methods: Six experts used a four-point Likert scale to assess the content validity of each of the 16 items of the physical activity enjoyment scale according to a provided definition of physical activity enjoyment. Based on the results, exploratory factor analysis was used to analyze survey data from a longitudinal study of 182 individuals (Measure 1 of Study 1: 15.75 ± 3.39 yrs; 56.6% boys, 43.4% girls), and confirmatory factor analysis (Measure 2 of Study 1: 15.69 ± 3.44 yrs; 56.3% boys, 43.7% girls) was used to analyze the survey data from a cross-sectional study of 3219 individuals (Study 2; 15.99 ± 3.10 yrs; 47.8% boys, 52.2% girls) to assess the construct validity of the new measure. To assess the reliability, test–retest reliability was assessed in Study 1 and internal consistency in Study 1 and 2. For the concurrent validity, correlations with self-reported and device-based physical activity behavior were assessed in both studies. Results: Four out of sixteen items were selected for PACES-S. Exploratory factor analysis and confirmatory factor analyses identified and supported its factorial validity (χ2 = 53.62, df = 2, p < 0.001; RMSEA = 0.073; CFI = 0.99; RFI = 0.96; NFI = 0.99; TLI = 0.96; IFI = 0.99). Results showed good test–retest reliability (r = 0.76) and internal consistency (a = 0.82 to 0.88). Regarding concurrent validity, the results showed positive correlations with a physical activity questionnaire (Study 1: r = 0.36), with a physical activity diary (Study 1: r = 0.44), and with accelerometer-recorded data (Study 1: r = 0.32; Study 2: r = 0.21). Conclusions: The results indicate that PACES-S is a reliable and valid instrument that may be particularly useful to measure physical activity enjoyment in large-scale studies. It shows comparable measurement properties as the long version of PACES.

Objective: Pragmatic assessment is critical because of its effective role in social and academic success. It can provide early intervention if the evaluations are made early in childhood. In this regard, an appropriate tool is necessary for the pragmatic evaluation of preschool children in Iran. The checklist of pragmatic behaviors (CPB) is an observational tool for assessing pragmatics in children aged 3-5 years. This study aims to develop a Persian version of the CPB and evaluate its psychometric properties. Materials & Methods: This is a methodological study conducted in 2018. The participants were 63 children in three age groups of 3, 4, and 5 years selected from kindergartens in Isfahan City, Iran, using a cluster sampling technique. The inclusion criteria were being 3-5 years old and Persian speaker. This study was conducted in two steps; translation and localization of the CPB to Persian and evaluating the validity and reliability of the Persian CPB. The studied variables were 25 pragmatic behaviors mentioned in the CPB. The test-retest reliability was estimated using 15 children (5 from each age group) in a 2-week interval. Scoring was based on the presence (verbal, nonverbal) or absence of the behavior. The internal consistency was estimated using the Cronbach α coefficient; discriminant validity was assessed concerning age, and criterion validity by measuring the CPB’s correlation with the ages and stages questionnaire (personal-social subscale) and the behavioral problem questionnaire. Nonparametric tests were used for factor analysis and estimating inter-rater agreement and test-retest reliability. The obtained data were analyzed in SPSS 21 and AMOS applications. Results: The Persian CPB’s total score significantly increased with the increase of age (P≤0.001). Factor analysis reported four factors for the Persian CPB. Criterion validity evaluation showed the moderate significant correlation of the CPB (r=0.58) with the personal-social subscale of age and stages questionnaire (ASQ), and its weak negative significant correlation (r=-0.28) with the behavior problem questionnaire. A Cronbach α of 0.83 was obtained for internal consistency, and a correlation coefficient of 0.665 (P=0.007) was reported for test-retest reliability. Conclusion: The Persian version of the CPB has acceptable psychometric properties. The differences in some items of this version compared to other versions may be because of differences in culture and language.

Abstract Background. The aim of this study was to translate, culturally adapt and validate an Italian version of the Athlete Fear Avoidance Questionnaire (AFAQ-I).Methods. We conducted a cross-sectional evaluation of the psychometric properties of the AFAQ-I in athletes with musculoskeletal injuries, culturally adapting it in accordance with international standards. Psychometric evaluation included exploratory factor analysis, reliability (internal consistency [Cronbach’s alpha], inter-item correlation, and test–retest reliability [intra-class correlation coefficient]). To examine construct validity, we compared (Spearman rank correlation) the AFAQ-I with a numerical pain rating scale (NPRS), the Pain Catastrophizing Scale (PCS), and the Fear Avoidance Beliefs Questionnaire subscales (Physical Activity, FABQ-PA; and Work, FABQ-W). We evaluated sensitivity to change through the minimum detectable change (MDC).Results. The AFAQ-I was administered to 133 university athletes with musculoskeletal injuries (26 females, mean age 25.3 ± 5 years, mean average pain duration 5.6 ± 8.7 months), and resulted acceptable. Factor analysis revealed a 1-factor 10-item solution (explained variance: 53%). Internal consistency was 0.78; average inter-item correlation 0.27; test–retest reliability ICC(2,1) 0.95. As hypothesized a priori, construct validity showed moderate correlations of the AFAQ-I with NPRS (ρ = 0.42), PCS (ρ = 0.59), FABQ-PA (ρ = 0.40) and FABQ-W (ρ = 0.34). The MDC was 4.42 points.Conclusion. The AFAQ-I is a valid Italian translation of AFAQ and demonstrates acceptable psychometric properties. We can recommend its use for clinical and research purposes.

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 personal-level 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 the IPOS. The reliability of Czech IPOS was tested with Cronbach alpha (for internal consistency), the intraclass correlation coefficient for total IPOS score and weighted Kappa (for test-retest reliability of individual items). Factor analysis was used for elucidating the construct (Exploratory Factor Analysis). Convergent validity was tested with correlation analysis (Spearman correlation) in a part of the sample, who completed also the Edmonton Symptom Assessment System (ESAS) and the Palliative Performance Scale (PPS). Results: The sample consisted of 140 patients (mean age 72; 90 women; 81 % oncological disease). The Cronbach alpha was 0.789; intraclass correlation was 0.88. The correlations of IPOS with ESAS was R= 0.4 and PPS R= -0.2. 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.

<p>The aim of this study is to evaluate the psychometric properties of the Remembered Relationships with Parents (RRP10) for Turkish university students. 373 students studying at Lefke European University participated in this research. The gender distribution of the subjects is 52.8% (n=197) for female and 47.2% (n=176) for male students. The reliability of RRP10 was assessed by internal consistency and test-retest reliability statistics. The validity of the scale was assessed by confirmatory and exploratory factor analysis and correlations between subscales and item analyses were examined. In addition, the correlation between RRP and Parental Bonding Instrument (PBI) was assessed by Pearson correlation coefficient method in order to see the criterion based validity. The internal consistency, Cronbach alpha and test-retest reliability coefficient of the scale were calculated. In order to assess the distinctive validity of the scale, a discriminant analysis was performed to determine whether the RRP10 scores of the participants who received under the cut-off score (≥10) is different than the RRP10 scores of the participants who received over the cut-off score according to the Beck Depression Inventory (BDI). As a result of the factor analysis, a two-factor structure similar to the original RRP10 study was found out. No correlation was observed between RRP10 Alienation and PBI Care subscales while highly significant criterion-relationship validity was observed between RRP10 Control and PBI Control subscales and a distinctive validity was observed in the statistical assessment of RRP10 and BDI. RRP10 test-retest coefficients and internal consistency coefficients show findings on the reliability of the scale. The psychometric properties of RRP10 are found to be satisfactory and could be used to assess remembered relationships with parents. RRP10 will be valuable in establishing initiatives or psycho-educative programs in order to regulate the mother-father and child relationships.</p><p> </p><p>Keywords: mother-father, alienation, control, reliability, validity, relationship</p>
