Background: The lack of reliable, valid and adequately standardized measures of mental illnesses in sub-Saharan Africa is a key challenge for epidemiological studies on mental health.  We evaluated the psychometric properties and feasibility of using a computerized version of the Major Depression Inventory (MDI) in an epidemiological study in rural Kenya. Methods: We surveyed 1496 participants aged 13-24 years in Kilifi County, on the Kenyan coast. The MDI was administered using a computer-assisted system, available in three languages. Internal consistency was evaluated using both Cronbach’s alpha and the Omega Coefficient. Confirmatory factor analysis was performed to evaluate the factorial structure of the MDI. Results:  Internal consistency using both Cronbach’s Alpha (α= 0.83) and the Omega Coefficient (0.82; 95% confidence interval 0.81- 0.83) was above acceptable thresholds. Confirmatory factor analysis indicated a good fit of the data to a unidimensional model of MDI (χ2 (33, N = 1409) = 178.52 p < 0.001, TLI = 0.947, CFI = 0.961, and Root Mean Square Error of Approximation, RMSEA = .056), and this was confirmed using Item Response Models (Loevinger’s H coefficient 0.38) that proved the MDI was a unidimensional scale. Equivalence evaluation indicated invariance across sex and age groups. In our population, 3.6% of the youth presented with scores suggesting major depression using the ICD-10 scoring algorithm, and 8.7% presented with total scores indicating presence of depression (mild, moderate or severe).  Females and older youth were at the highest risk of depression. Conclusions: The MDI has good psychometric properties.  Given its brevity, relative ease of usage and ability to identify at-risk youth, it may be useful for epidemiological studies of depression in Africa.  Studies to establish clinical thresholds for depression are recommended. The high prevalence of depressive symptoms suggests that depression may be an important public health problem in this population group.

Introduction: Depression has become increasingly prevalent in Chinese international students in South Korea. For this population, therefore, accurate assessment of mood disorders, particularly depression, is critically important. The 10-item Center for Epidemiological Studies Depression Scale (CES-D 10) is commonly used to measure depression in both clinical and non-clinical populations. Thus, this study examined the CES-D 10’s factor structure and psychometric properties in Chinese international students. Methods: Study participants were 250 Chinese international students aged 18–23, attending a four-year university in Korea; they completed the Chinese version of the CES-D 10. Based on relevant theories and empirical research, confirmatory factor analysis was employed to examine the adequacy of three competing models’ factor structure. Internal consistency reliability was assessed using Cronbach’s alpha, and test-retest reliability using the Pearson correlation coefficient. Results: Confirmatory factor analysis suggested that the two-factor model comprised of depressive affect/somatic retardation and positive affect had the best fit. The CES-D 10 showed satisfactory internal consistency and test-retest reliability in Chinese international students. Conclusion: The CES-D 10 demonstrated strong psychometric properties in this Chinese international student sample, and results suggest that the CES-D scale is a useful screening tool for depressive symptoms. Therefore, the CES-D 10 could be used as a depression screen for international students at the population level and in health clinics.

Objective To determine the psychometric properties of the Person-Centered Therapeutic Relationship in Physiotherapy Scale (PCTR-PT) in order to find the most appropriate fit for the tool. Methods Patients who had received treatment at the physiotherapy service of nine hospitals in Spain were invited to complete the 31 items of the PCTR-PT scale. To select the most appropriate items of the PCTR-PT, an exploratory factorial analysis (EFA) was performed using the maximum likelihood and oblique rotation (promin) methods. Factor validity, goodness-of-fit and psychometric properties were analyzed by confirmatory factor analysis (CFA). Convergent (CFA) and discriminant validity were calculated. Internal consistency was verified using the Cronbach's alpha coefficient. The intraclass correlation coefficient (ICC) was used to examine temporal stability. Results 366 patients over 18 years old who had received, at least, 15 physiotherapy treatment sessions completed the questionnaire. The results of the exploratory factor analysis revealed a tool with 15 items in four factors [Relational Bond (N items = 4); Individualized Partnership (N items = 4); Professional Empowerment (N items = 3) and Therapeutic Communication (N items = 4)], explaining 78.4% of the variance of the total variables of this tool. The confirmatory factor analysis further confirmed the four-structure model. Reliability of the tool was approved by Cronbach's alpha in all four dimensions, as all were above .70, ranging from .84 (Individualized Partnership) to .91 (Professional Empowerment). = 0.94. Test-retest was performed with two-week intervals, indicating an appropriate stability for the scale (ICC = 0.900). Conclusion The Person-Centered Therapeutic Relationship in Physiotherapy Scale (PCTR-PT) is a useful, valid and applicable instrument to evaluate the person-centered therapeutic relationship during physiotherapy interventions. It would be interesting to investigate the predictive capacity (sensitivity and specificity) of the PCTR-PT scale.

The current study tested the one-dimensionality of the Center for Epidemiological Studies Depression Scale for Suicidal Ideation (CES-D-SI) and its reliability among high school students in Santa Marta, Colombia. A total of 1,462 tenth and eleventh-grade students from public and private schools completed the CES-D-SI. The students were between 13 and 17 years ( M = 16.0, SD = 0.8), 60.3% were female, and 55.3% were in the tenth grade. A confirmatory factor analysis (CFA) was conducted, and the chi-square, root mean square error of approximation (RMSEA), comparative fit index (CFI), Tucker-Lewis index (TLI), and standardized root mean square residual (SRMR) statistics were calculated. The internal consistency of the dimension was calculated using Cronbach’s alpha and McDonald’s omega coefficients. The results of the CFA were as follows: chi-square = 26.51, df =2, p = .001; RMSEA = .092; 90% confidence interval = .063–.124; CFI = .983; TLI = .950; and SRMR = .019. Cronbach’s alpha coefficient was .75, and McDonald’s omega coefficient was .77. As conclusions, the scale exhibited a unidimensional structure similar to that in other studies and presented good reliability values. Hence, its use is recommended to screen suicidal ideation in school-aged adolescents in Santa Marta, Colombia.

Abstract Background The use of validated questionnaires to assess the perception of teamwork can be an early step in improving team training activities. Team-STEPPS® Teamwork Perception Questionnaire (T-TPQ) has been adapted and validated for hospital setting use in several countries. Due to linguistic and cultural differences, there is need to test the psychometrics of the adapted versions. However, no research have not yet assessed the psychometric properties of the Persian T-TPQ. Therefore, this study aims to assess the internal consistency reliability and construct validity of an Iranian version of the Team-STEPPS® Teamwork Perception Questionnaire (IR-T-TPQ). Methods To conduct this study, we undertook a cross-sectional survey approach between May 2020 and January 2021. In total, 404 nurses were recruited by convenience sampling technique from 10 teaching hospitals in Tabriz, Iran. Internal consistency reliability was analyzed using Cronbach’s alpha coefficient. Confirmatory factor analysis was performed to test the construct validity of the instrument. Results Cronbach’s alpha coefficients for each subscale were acceptable, ranging from 0.84 to 0.92, as well as for the total IR-T-TPQ (α = 0.96). The confirmatory factor analysis demonstrated a five-factor model, all of whose fit indices were acceptable, except for the goodness-of-fit index and normed fit index (χ2 (df) 1332 (550), p < 0.001, Normed chi-square (χ2/df) = 2.423, RMSEA = 0.059, TLI = 0.897, CFI = 0.904, AGFI = 0.814). Conclusions The psychometric properties of the IR-T-TPQ resulted in acceptable levels of internal consistency reliability and construct validity, respectively, in Iranian hospital nurses. Further study is needed to compare the teamwork level of nurses in various settings or to evaluate the effectiveness of the teamwork intervention using this validated and reliable tool.

Background: Social interactions require social cognition. Social cognition and its shortcomings could be assessed by questionnaires and interviews. Objectives: The present study aimed to examine the psychometric properties of the Persian versions of the Observable Social Cognition Rating scale (OSCARS) in students. Methods: This correlational study was conducted on 250 male and female students at the high schools of Dezfoul, Iran during 2019 - 2020. The participants were selected via multistage random sampling. The reliability, congruent validity, and concurrent validity of the Persian version of the OSCARS were evaluated using the teacher’s form of the OSCARS and the cognitive abilities questionnaire. The validity of the OSCARS was measured by confirmatory factor analysis, and its congruent validity and reliability were measured using the Cronbach’s alpha and split-half method. Results: The Cronbach’s alpha value of the entire scale, teacher’s form, and cognitive abilities questionnaire was 0.65, 0.60, and 0.85, respectively. The split-half coefficient for the entire scale was estimated at 0.60, and the correlation between the OSCARS and the teacher’s form was 0.35. Moreover, the correlation between the OSCARS and cognitive abilities questionnaire with the social cognition subscale was 0.15 and 0.13, respectively. The results of confirmatory factor analysis indicated the excellent fitness of the OSCARS structure (RMSEA = 0.02). Conclusions: According to the results, the Persian version of the OSCARS has good reliability and validity.

In order to ensure the construct validity of the three-factor model of the Multi-dimensional Scale of Perceived Social Support (MSPSS), and based on the assumption that it helps users differentiate between sources of social support, in this study a revised version was created and tested. The aim was to compare the level of model fit of the original version of the MSPSS against the revised version - which contains a minor change from the original. The study was conducted on 486 medical students who completed the original and revised versions of the MSPSS, as well as the Rosenberg Self-Esteem Scale (Rosenberg, 1965) and Beck Depression Inventory II (Beck, Steer, & Brown, 1996). Confirmatory factor analysis was performed to compare the results, showing that the revised version of MSPSS demonstrated a good internal consistency - with a Cronbach's alpha of .92 for the MSPSS questionnaire, and a significant correlation with the other scales, as predicted. The revised version provided better internal consistency, increasing the Cronbach's alpha for the Significant Others sub-scale from 0.86 to 0.92. Confirmatory factor analysis revealed an acceptable model fit: χ2 128.11, df 51, p < .001; TLI 0.94; CFI 0.95; GFI 0.90; PNFI 0.71; AGFI 0.85; RMSEA 0.093 (0.073-0.113) and SRMR 0.042, which is better than the original version. The tendency of the new version was to display a better level of fit with a larger sample size. The limitations of the study are discussed, as well as recommendations for further study.

Objectives: In the context of the epidemic of coronavirus and its psychological effect, it is necessary to develop appropriate tools for measuring the aspects of its psychological pathology. Therefore, this study aims to determine coronavirus anxiety›s psychometric properties using a 5-point Likert scale (Sherman A. Lee) in the Iranian statistical population. Methods: In this study, 399 men and women from the adult population of Kermanshah were studied by the available sampling method. The Fear of COVID-19 Scale (FCV-19S), Difficulties in Emotion Regulation Scale(DERS), as well as the second version of the Acceptance and Action Questionnaire (AAQ-II) were used for convergent validity and divergent validity, respectively. Internal consistency method using Cronbach’s alpha was used to analyze data, and confirmatory factor analysis using Lisrel-8.8 software was used for construct validity. Results: Cronbach’s alpha was found to be 91.5 for the scales overall score. CAS found a positive and significant correlation between the coronavirus anxiety scale and the sub-components of difficulty in emotion regulation (except for problems engaging in goal-directed behaviors). Still, he also found that there was a negative correlation between acceptance and action. Furthermore, the results of the confirmatory factor analysis indicated that the single-factor structure is well-suited Conclusion: Covid-19 related anxiety can be disproportionate and unnecessary and cause many psychological problems. The Iranian version of the coronavirus anxiety Scale reflected desirable validity and reliability and could be used as a short and valid screening tool for measuring coronavirus anxiety measurement.
