Objective: The aim of the present study was to examine the reliability and validity of the short form of the Reynolds Adolescent Depression Scale (RADS-SF). Method: A sample of 9567 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey that included the full-length version of the RADS. The reliability and validity of the subset of items that make up the RADS-SF and its comparability to the original version were assessed using Cronbach's alpha, kappa statistics, correlations between the two versions of the instrument, confirmatory factor analysis and correlation to other questions in the survey considered likely to be associated with depression. Results: The RADS-SF had Cronbach's alpha of 0.88, was strongly correlated (0.95) to the RADS, had acceptable fit for the data (χ2=2823.27, df=35, comparative fit index=0.96, root mean square error of approximation=0.092, 90% confidence interval=0.089–0.095, standardized root mean square residual=0.042), showed configural invariance across gender, age and ethnic groups, and was strongly correlated with other depression-related questions, such as suicidal ideation (r=0.48). While the overall agreement for classification of depression by the two scores was good (κ=0.75), a higher percentage of students were classified as having depressive symptoms using the recommended RADS-SF cut-off point of 26 compared with the RADS criteria. Conclusions: The RADS-SF was found to have acceptable reliability and validity and to have psychometric properties comparable to the RADS in a large population of New Zealand adolescents.

Objective: To examine aspects of the reliability and validity of the Reynolds Adolescent Depression Scale (RADS) in measuring depression in New Zealand adolescents of all major ethnic groups. Method: A sample of 9699 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey which included the RADS. Data from this survey have been used to assess some aspects of the reliability and validity of the RADS in the New Zealand context across different ethnic groups. Cronbach's alpha, itemtotal score correlations, correlation to other questions and a factor analysis were done in order to examine the internal reliability, content validity, convergent validity and construct validity of the data and compare to the original Reynolds validation study. Results: Tests of the scale resulted in scores over 0.90 on Cronbach's alpha and high itemtotal score correlations, with a median correlation of 0.62 and 25 of the 30 correlations measuring more than 0.5. The scores were found to have similar factor structure to the original scale and the correlations to other depression related questions indicate acceptable concurrent validity. Conclusions: On all of the tests conducted, the RADS was found to have acceptable reliability and validity for New Zealand adolescents across the major different ethnic groups, indicating that it is a valid and appropriate instrument to use with New Zealand adolescents.

Background:In the literature, there is a lack of questionnaires, which is evaluate patients with psoriatic arthritis (PsA) from a biopsychosocial perspective.Objectives:This study was planned to examine the reliability and validity of the BETY- Biopsychosocial Questionnaire (BQ) in individuals diagnosed with PsA.Methods:Test-retest method was used to examine the reliability of the BETY-BQ. In comparing the reliability of test-retest results, intraclass coefficient (ICC) was checked. For the internal consistency analysis of the BETY-BQ, the total score of the responses given to the first filled scale was calculated and the Cronbach’s Alpha coefficient was found. Psoriatic Arthritis Quality of Life Questionnaire (PsAQoL), Health Assessment Questionnaire (HAQ), Hospital Anxiety and Depression Scale (HADS) and Short Form-36 (SF-36) were used in the validity study of 150 individuals with PsA included in the study.Results:Test-retest method and intraclass coefficient were examined for reliability analysis (for 30 patients). The correlation (r = 0.844, p <0.001) of the answers given to the BETY-BQ by individuals with 30 PsA after one week interval was very high. While the ICC coefficient (0.915, p <0.001) showed excellent reliability. The Cronbach’s Alpha coefficient (0.940) was examined for internal consistency and the internal consistency of the scale was also found to be excellent. As a result of statistical analysis, the correlation between the scales used and the BETY-BQ was found between r = -0.432 and 0.807 (p <0.001).Conclusion:With this study, it was concluded that the BETY-BQ is a reliable and valid assessment tool in individuals diagnosed with PsA, and is also a biopsychosocial tool that can be used to evaluate individuals with PsA.References:[1]Unal E, Arin G, Karaca Nb, Kiraz S, Akdoğan A, Kalyoncu U, et al.

Patient-centredness in care is a core healthcare value and an effective healthcare delivery design requiring specific nurse competences. The aim of this study was to assess (1) the reliability, validity, and sensitivity of the Finnish version of the Patient-centred Care Competency (PCC) scale and (2) Finnish nurses’ self-assessed level of patient-centred care competency. The PCC was translated to Finnish (PCC-Fin) before data collection and analyses: descriptive statistics; Cronbach’s alpha coefficients; item analysis; exploratory and confirmatory factor analyses; inter-scale correlational analysis; and sensitivity. Cronbach’s alpha coefficients were acceptable, high for the total scale, and satisfactory for the four sub-scales. Item analysis supported the internal homogeneity of the items-to-total and inter-items within the sub-scales. Explorative factor analysis suggested a three-factor solution, but the confirmatory factor analysis confirmed the four-factor structure (Tucker–Lewis index (TLI) 0.92, goodness-of-fit index (GFI) 0.99, root mean square error of approximation (RMSEA) 0.065, standardized root mean square residual (SRMR) 0.045) with 61.2% explained variance. Analysis of the secondary data detected no differences in nurses’ self-evaluations of contextual competence, so the inter-scale correlations were high. The PCC-Fin was found to be a reliable and valid instrument for the measurement of nurses’ patient-centred care competence. Rasch model analysis would provide some further information about the item level functioning within the instrument.

Background: Infertility is a public health problem and can lead to depressive symptoms. In recent years, the WHO-five Well-being Index (WHO-5) has been used as a screening measure for depression, but study on psychometric properties in people with infertility is scarce. The objective of this study was to examine the reliability and validity of the Persian version of the WHO-5 in people with infertility. Methods: Overall, 539 infertile patients from a referral infertility center in Tehran, Iran in the period between May and Aug 2017, completed the WHO-5, along with other psychological measures: the Patient Health Questionnaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS). Construct validity and internal consistency of WHO-5 were evaluated using confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with PHQ-9 and HADS. Results: The prevalence of poor well-being was 44.3% and that of depression was 18.6%. CFA confirmed the unidimensional factor structure of the WHO-5. Internal consistency of the WHO-5 was good (Cronbach’s alpha=0.858). The WHO-5 significantly correlated with the PHQ-9 (r=-0.522), HADS-anxiety (r=-0.524) and HADS-depression (r=-0.630), confirming convergent validity. Conclusion: The WHO-5 is a short and easy to use questionnaire with satisfactory reliability and validity that appears suitable for use as a screening test for depressive symptom in infertile people. In addition, the prevalence of depression and poor well-being was very high in this population.

Summary The Quality of Life Enjoyment and Satisfaction Questionnaire – Short Form is the most often used scale for measuring the quality of life of patients with psychiatric diseases. The aim of this research was to analyze the possibilities for measuring the quality of life in clinical conditions on the sample of patients with schizophrenia by using this scale. The study was conducted on the group including 153 patients with schizophrenia at the Institution for Accommodation of Adults “Male Pčelice”, Kragujevac. The study was observational and cross-sectional. The reliability of questionnaire was examined by using Cronbach’s alpha. The two tests of factor analysis adequacy were used, Spherical Bartlett’s Test and Keiser-Meyer-Olkin test (sampling adequacy). Validation was performed by calculating the correlation (validation by criteria). The Quality of Life Enjoyment and Satisfaction Questionnaire – Short Form was reliable (Cronbach’s alpha coefficient was 0.730) and valid. According to Catell criterion two domains were applied. This two-component solution explained the total of 37.80% variance, whereby the contribution of the first domain was 27.1% and the second 10.7%. The Quality of Life Enjoyment and Satisfaction Questionnaire – Short Form is suitable for everyday clinical evaluation of the patients with schizophrenia.

Background and Purpose: Globally, depressive symptoms are a leading contributor to years lived with disability. The Center for Epidemiological Studies–Depression (CES-D) scale has been used extensively to quantify depression; yet, its psychometric properties remain contentious. This study examined the reliability and factor structure of the CES-D in the MacArthur Foundation’s Midlife in the United States Study (MIDUS), a nationally representative cohort study of noninstitutionalized, English-speaking adults aged 24–74 years. Methods: Internal consistency (Cronbach’s alpha) and confirmatory factor analysis (CFA) were used to examine the reliability and factor structure of the CES-D. Results: There were 1,233 participants who were included in the analysis (mean age = 57.3 years [SD = 11.5], 56.7% female). Cronbach’s alpha of .90 was observed. The 4-factor model had the best model fit. Conclusions: High internal consistency was demonstrated alongside a replication of the original 4-factor structure. Continued use of the CES-D in noninstitutionalized populations is warranted.

This study examined psychometric properties of the Levenson’s Locus of Control Scale among Iranian infertile patients. In all, 312 infertile patients completed the Levenson’s Locus of Control Scale and Hospital Anxiety and Depression Scale. The confirmatory factor analysis indicated that the original three-factor model of Levenson’s Locus of Control Scale was adequate ( χ2/ df = 2.139; goodness-of-fit index = 0.88; root mean square error of approximation = 0.061; and standardized root mean square residual = 0.076). The Cronbach’s alpha of the subscales ranged from 0.56 to 0.67. The Levenson’s Locus of Control Scale subscales significantly correlated with anxiety and depression, showing an acceptable convergent validity. In conclusion, the Levenson’s Locus of Control Scale has adequate reliability and validity and can be used to measure locus of control orientation in Iranian infertile patients.

Introduction: Edinburgh Postpartum Depression Scale (EPDS) is a tool used to assess the risk of postpartum depression (PPD). In this study we determined the reliability and validity of the Malay version of EPDS when administered at two different time points in the postpartum period. Materials and Methods: This cross-sectional study design was carried out between May and September 2017 at three government primary healthcare clinics located in Batang Padang district, a suburban area of Perak state in Peninsular Malaysia. We recruited a total of 89 women; 41 women were in the early postpartum period (1-30 days) and 48 women were in the late postpartum period (31-120 days). Cronbach's alpha coefficient, inter-item correlation, and corrected item-total correlation were used to assess the internal consistency. The concurrent validity was assessed using Spearman’s correlation. The data were analyzed using SPSS version 20 and R 3.4.2. Results: The Cronbach’s alpha for the first and second group was 0.78 and 0.62, respectively, which indicated satisfactory reliability. At both time periods, removing Item 2 from the scale resulted in a significant increase in Cronbach’s alpha (to 0.847 and 0.709, respectively). As expected, the EPDS scores correlated moderately with the BDI-II scores (1−30 days: Spearman's rho = 0.65, p < 0.01; 31−120 days: Spearman's rho = 0.73, p < 0.01). Conclusion: The Malay version of the EPDS is a reliable screening instrument for detecting postpartum depression. It showed reasonability and feasibility and can be used in postpartum clinical settings or for assessing intervention effects in research studies. Furthermore, as our results indicated, removing Item 2 from the Malay version would increase the internal consistency of the EPDS.

There are various instruments to measure attitudes toward persons with disabilities (PwD). The Multidimensional Attitudes Scale (MAS) toward PwD is a three-dimension scale with good psychometric properties; the Spanish version has been validated with a four-factor structure. Aim: To examine the factor structure of a cross-cultural adapted version of the Spanish MAS towards deaf persons in a sample of Chilean dental students. Methods: This cross-sectional study involved five Chilean public health experts that reviewed the scale for obtaining a preliminary version of a 30-item modified MAS towards deaf persons; a pilot with 15 dental students was performed, and a final sample composed of 311 students was included. For the exploratory factor analysis (EFA), maximum likelihood estimation (ML) for determining the number of factors and parallel analysis (PA) was used, with Oblimin for the rotation method. Cronbach’s alpha was used to assess reliability. The root mean square error of approximation (RMSEA), comparative fit index (CFI), incremental fit index (IFI), goodness of fit index (GFI), Tucker-Lewis fit index (TLI-NNF) and root mean square of residuals (RMSR) were used to assess model fit. Results: All items had a normal distribution with the exception of items 7 and 10. The four-factor structure without item 10 in this EFA presented an adequate Cronbach’s alpha (>0.83), suggesting acceptable reliability. RMSEA, TLI-NNFI, RMSR, GFI and CFI indices suggested a good fit of the model and were consistent with the literature. Conclusion: The Spanish modified version of the MAS towards deaf persons has a four-factor structure, which in consistent with a previous version of the MAS.

Abstract Background: Behavioral Activation (BA) is an evidence-based treatment that aims to help the individual to stay active and reduce avoidance behaviors, as a means to reduce depressive symptoms. This study aims to describe the adaptation process and evaluate the psychometric properties of the Behavioral Activation for Depression Scale Short Form (BADS-SF) in its Brazilian and Peruvian version.Methods: Data were collected as part of a randomized trial with 880 participants in Brazil and 432 in Peru. The content validity was assessed using the Content Validity Index (CVI). Principal Component Analysis (PCA) method was applied to evaluate the factorial distribution. Sampling adequacy was assessed by Bartlett’s test of Sphericity and Kaiser-Meyer-Olkin measure. Cronbach’s alpha coefficient was calculated to assess internal consistency.Results: CVI in Brazil was 0.92 and in Peru 0.87. The two-factor solution of the original scale is sustained (activation and avoidance), accounting for 50.6 and 54% of the total variance in Brazil and Peru, respectively. Cronbach’s alpha in Brazil was 0.55 and 0.66 in Peru for the overall scale. KMO was 0.769 and 0.790 for Brazil and Peru, respectively. Bartlett’s test of Sphericity had significance of 0.000 for both samples. Conclusion: Both studied versions of the BAD-SF showed coherent structure and internal consistency. We recommend different distribution of the items into the subscales.
