Background and Purpose: Assessing the stress of patient with diabetes requires reliable and valid instruments. This study evaluated the measurement properties of the Brazilian version of the Diabetes Distress Scale (B-DDS). Methods: This cross-sectional study enrolled 139 patients with Type 2 diabetes mellitus (DM2) receiving outpatient treatment. Reliability and construct validity were estimated through convergent validity and confirmatory factor analysis. Results: Evidence of reliability was obtained—Cronbach alpha = .87 and intraclass correlation coefficient (ICC) = .93. Significant positive correlations of moderate-to-strong magnitudes were observed between the dimensions of the DDS and the total score of the PAID; the confirmatory factor analysis supported the four dimensions of the original instrument. Conclusions: The B-DDS is reliable and valid for evaluation of the stress related to diabetes mellitus.

The objective of the research was to evaluate the validity and reliability of the Diabetes Distress Scale in patients with type 2 diabetes in Turkey. Materials and Methods. Our study was conducted between September 2016 and January 2017 and included 170 patients with type 2 diabetes. The Personal Information Form and Diabetes Distress Scale were used as a data collection tool. Statistical analysis was performed using SPSS 23.0 and SAS package program. Results. According to the results of the research, Cronbach’s alpha reliability for the total scale was 0.91. The model fit indices for the revised confirmatory factor analysis model failed to meet the criteria for acceptability: the GFI was 0.8185, the CFI was 0.9316, the Bentler - Bonett (1980) NFI was 0.9005, and the RMSEA was 0.1067. In our study, exploratory factor analysis provided support for the three-factor model: [I] emotional and regimen-related distress, [II] health professional-related distress, [III] diabetes-related interpersonal distress. Conclusions. When the translation and cultural adaptation process have been considered, the Diabetes Distress Scale is a valid and reliable tool for the Turkish community. It is recommended to be used in the studies and clinical trials.

Purpose: The purpose of this study is to translate the Perceived Therapeutic Efficacy Scale (PTES) into Korean and investigate its validity and reliability. Methods: The authors conducted a cross-sectional survey using baseline data from a randomized controlled study to psychometrically validate the PTES-Korean (PTES-K) among 108 adults with type 2 diabetes from an outpatient clinic at a university-affiliated hospital in Korea. The original PTES was forward-translated and back-translated to ensure translation equivalence of the PTES-K. Structured questionnaires were used for psychometric evaluation; exploratory and confirmatory factor analysis assessed validity, and Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were used for reliability. Results: The interitem correlation analyses revealed that 5 items were redundant; thus, the scale was reduced to 5 items. A 1-factor model explained 76.85% of the variance; confirmatory factor analysis showed that this model adequately fit the data. The ICC for test-retest reliability was .78; Cronbach’s alpha was .92. The PTES-K showed significant associations with the scores of diabetes self-care activities for physical activity, quality of life, and depressive symptoms. Participants with good glycemic control and regular physical activity tended to have a higher score on the PTES-K than their counterparts, demonstrating known-groups validity. Conclusions: The cross-cultural applicability, reliability, and validity of the PTES-K were confirmed. The PTES-K may be used in clinical settings to examine the potential role of perceived therapeutic efficacy for physical activity in enhanced glycemic control among patients with diabetes.

Introduction: We aimed to evaluate the psychometric properties of the 26-item Expanded Prostate Cancer Index Composite (EPIC-26) for measuring the quality of life in patients treated for localized prostate cancer. The EPIC-26 is a patient-reported outcome instrument recommended for use with patients treated for localized prostate cancer. Methods: This study is based on data collected prospectively between September 2014 and February 2017 in Alberta, Canada. Men were treated with either radical prostatectomy or radiation therapy and administered the EPIC-26. Responses to the EPIC-26 were the primary outcome. Construct validity was measured using confirmatory factor analysis. Reliability was measured using Chronbach’s alpha and item-total correlation. Ceiling and floor effects were also investigated. Results: EPIC-26 response data from 205 participants (prostatectomy =138; radiation=60; both=7) were used in this analysis. The EPIC-26 was administered an average of 33.8 weeks after treatment. The confirmatory factor analysis model did not meet the threshold for adequate fit. Several items had near-zero factor loadings and were non-significant. Four out of the EPIC- 26’s five domains met the acceptable reliability threshold based on Cronbach’s alpha. Ceiling effects were observed in four out of five domains. Conclusions: The EPIC-26 demonstrated poor construct validity, adequate reliability, and large ceiling effects. Several issues were observed, suggesting that the instrument’s five domains were not well-defined by their respective items. The original EPIC’s conceptual framework should be reviewed and the shortened instrument revised to improve its performance for measuring post-treatment quality of life.

The literature suggests limitations to Dickman’s dysfunctional impulsivity (DI) scale. These concerns are centered on the measurement properties of this scale and on its reliance on student samples. To address these criticisms, the DI was administered to a random adult sample (n = 649, mean age 43.83 ± 13.46 years), 13% of whom were university educated. Confirmatory factor analysis (CFA) did not support the fit of the posited 12-item DI scale. The full sample was randomly divided. Principal components analysis was applied to one sample (n = 328), resulting in a 9-item model. This new model was then replicated using CFA in the second sample (n = 321). Cronbach’s α for the 9-item model was 0.84 and item-total correlations were > 0.39. The 30th and 70th percentile scores from the DI distribution of scores were used to categorize participants with low and high DI. The high-DI group was associated with significantly more driving distractions and lane crossings.

The aim of this study was to assess the psychometric properties of the Brazilian version of the Coach–Athlete Relationship Questionnaire (CART-Q) for coaches. Subjects were 173 coaches (20–65 years old) from both sexes, from individual and team sports, ranging from amateur to national level; the instruments were the Coach version of CART-Q translated and adapted to Portuguese and the Athletic Satisfaction Scale adapted for coaches. Data analysis consisted of confirmatory factor analysis, internal consistency (Cronbach's alpha and composite reliability), concurrent validity (Spearman correlation), and temporal stability (intraclass correlation coefficient, ICC). Confirmatory factor analysis revealed a model with 11 items presenting adequate fit (χ2/df = 2.68; comparative fit index = 0.92; goodness-of-fit index = 0.91; Tucker–Lewis index = 0.90; root mean square error of approximation = 0.10) and the existence of a second-order factor (coach–athlete relationship). The scale has shown satisfactory internal consistency (composite reliability > 0.70 and α > 0.70). Concurrent validity assessment presented significant relationships (r > 0.40) with all coach satisfaction variables and temporal stability after 15 days was also adequate (0.65 < ICC < 0.88). It was concluded that the Brazilian version of the CART-Q Coach is adequate to assess coaches' perception regarding the relationship with their athletes.
