Cross-Cultural Adaptation, Reliability, and Validity of a Brazilian of Short Version of the Posttraumatic Diagnostic Scale.

ABSTRACT: Background: A short version of the Posttraumatic Diagnostic Scale (PDS) comprising only re-experiencing symptom items has been recently validated on Japanese adults. This short-version-PDS had good psychometric properties among Japanese adults with and without posttraumatic stress disorder (PTSD). The aim of this study was to translate and culturally validate the short-version-PDS for the Brazilian sociolinguistic context. Methods: A translation of the short-version-PDS was performed based on established guidelines. We enrolled 53 patients with PTSD as a potential comorbidity. The translation and cross-cultural adaptation of the short-version-PDS included forward and back-translation by a Japanese Brazilian researcher and a certified translator; synthesis was achieved by consensus, backward translation, pilot test, and finalization. Content validity coefficient (CVC) was used to assess quality of adaptation. Internal consistency was calculated using Cronbach's alpha coefficient. Spearman correlations were between the new short-version-PDS and the Brazilian version of the posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), and a receiver operating characteristic (ROC) curve was used to determine the best cut-off values for the short-version-PDS. Results: The short-version-PDS was well accepted by all subjects, none of the questions were experienced as inappropriate, and all questions of the 3 items were judged important. Item 1 presented CVCt = 0.92; item 2 had a CVCt = 0.87 and item 3 had a CVCt = 0.95. The internal consistency of the final version as measured by Cronbach's alpha was 0.78. The short-version-PDS scale correlated positively with the DSM-5 scale with a Spearman rho of 0.64 (95%CI [0.4-0.8], p < 0.001). The receiver operating characteristic (ROC) curve value was 0.97 (95%CI [0.9-1.0], p < 0.001). The cut-off score for a maximum Youden Index of 0.8 to distinguish moderate from severe from slight PTSD was > 31.0 with sensitivity and specificity are 86.4 and 93.5%, respectively. Conclusions: This Brazilian Portuguese version of the short-version-PDS had good psychometric properties among Brazilian adults with and without PTSD. Transferability and generalizability of the cut-off scores should be further analyzed.

Project description:Mediterranean Diet management for people with cardiovascular disease (CVD) or CVD risk is supported by evidence. However, there is no valid Chinese language instrument for the measurement of adherence to this diet. The objective of this study was to generate a Chinese version of the Mediterranean Diet Scale (MDS-Chinese) and to validate a self-administered version with Chinese participants with CVD or CVD risk. The MDS-Chinese was created by translation and cultural adaptation and tested for psychometric properties. A panel of 10 experts in the field, who evaluated the MDS-Chinese content, showed that the content validity index ranged from 0.88 to 1.00. Sixteen native Chinese speakers with CVD or CVD risk evaluated the clarity of the MDS-Chinese, and the resulting instruction and items clarity scores ranged from 9.2 to 10.0. A total of 326 participants completed the MDS-Chinese and a Chinese version of the Coronary Artery Disease Education Questionnaire-Short Version (CADE-Q SV). Analysis indicated that the MDS-Chinese has 4 factors, and the Pearson's correlation between the MDS-Chinese and CADE-Q SV was 0.73. Fifty randomly selected participants completed the MDS-Chinese again with a 1-week interval to assess reliability. Internal consistency was acceptable (Cronbach's α was 0.62) and the inter-class correlation reliability coefficients (ICC) for each item ranged from 0.73 to 0.88. This study showed that the MDS-Chinese has acceptable reliability and validity for use among those in the Chinese population with CVD or CVD risk. Given that diet is one of the key secondary prevention strategies for management in cardiac rehabilitation, the MDS-Chinese instrument may be a useful and convenient tool for use with those in the Chinese population with CVD or with high risk of CVD, to monitor the level of Mediterranean diet (MD) adherence, information which is important for clinical practice. In addition, the establishment of the MDS-Chinese gives a fundamental tool for diet-related CVD research in the Chinese population. Moreover, employment of the MDS-Chinese in the Chinese community may improve awareness of the importance of a healthy diet in CVD prevention and management.

Project description:BackgroundThe Exercise Adherence Rating Scale (EARS) is a commonly used outcome tool, which helps to identify the adherence rate of exercises and reasons for adherence and non-adherence. There is no evidence of the availability of any measurement tools to assess exercise adherence in the Nepalese context and cultural background. Therefore, we conducted a cross-cultural adaptation of the EARS into the Nepali language and investigated its reliability and validity.MethodsCross-cultural adaptation of the EARS was done based on Beaton guidelines. Psychometric properties were evaluated among 18 participants aged 18 years or older with pre-diabetes or confirmed diagnosis of any disease who were prescribed with home exercises by physiotherapists. Any disease that limited participants from doing exercise and individuals unwilling to participate were excluded. Reliability was evaluated through internal consistency, using Cronbach's alpha. Exploratory Factor Analysis (EFA) was performed to explore construct validity and confirm its unidimensionality. Receiver Operating Characteristic (ROC) curve was analyzed to identify cut-off score, sensitivity and specificity of the tool.ResultsThe Cronbach's alpha was 0.94 for EARS-adherence behavior. The EFA of 6-items adherence behavior revealed the presence of one factor with an eigenvalue exceeding one. The scree-plot suggested for extraction of only one factor with strong loading (75.84%). The Area Under the Curve was 0.91 with 95% confidence interval 0.77-1.00 at p = 0.004. The cutoff score was found 17.5 with 89% sensitivity and 78% specificity.ConclusionsThe EARS was cross-culturally adapted to the Nepali language. The reliability and construct validity of the Nepali version of the EARS were acceptable to assess exercise adherence in Nepali-speaking individuals. This validated tool might facilitate the evaluation of exercise-related interventions. Future studies could investigate other psychometric properties of the Nepali EARS.

Project description:BackgroundCore vestibular symptoms are vague, hard for patients to describe, and difficult for examiners to quantify. Reliable and validated patient-reported outcome measures (PROMs) have obtained acceptance and popularity in the specialty of vestibular disorders. In Kurdish, there is a critical shortage of such measures. The aim of this survey was to assess the psychometric properties of a central Kurdish version (VSS?-?SF?- CK) of the Vertigo Symptom Scale-Short Form (VSS?-?SF).MethodsThe study utilized a regulated process of cross-cultural adaptation to produce the VSS?-?SF?-?CK. We examined its psychometric properties by using a cross-sectional survey. Owing to a non-normal distribution, both principal axis factoring and polychoric correlation were used to examine the structure. The internal consistency of the scales was evaluated using Cronbach's alpha coefficient (?) and composite reliability. The discriminant validity was evaluated using the heterotrait-monotrait ratio of correlations (HTMT.85) and the Fornell-Larcker criterion. To assess convergent validity, the instrument was correlated with two comparators.ResultsThe participants (n =?195) were composed of 165 patients with vestibular symptoms (mean?-?age 45?±?15.8, range 61?years; 56.4% women) and 30 healthy participants (mean?-?age 35?±?18.6; range 52?years; 60% women). Based on the scree plot, along with other criteria such as Horn's parallel analysis and minimum average partial, two factors were extracted: vestibular (VSS?-?V) and autonomic-anxiety (VSS?-?AA). Both constructs showed a robust structure in terms of adequate loadings and weak cross-loadings. The scales' ?s were 0.81, 0.81, and 0.87 for VSS-V, VSS-AA, and the total scale (VSS?-?T), respectively. Discriminant validity was established with a value of 0.71 for HTMT (<?0.85). Spearman's correlation supported the study's hypotheses and confirmed the convergent validity. Intraclass correlation coefficients revealed high external reliability: test-retest results were 0.93, 0.94, and 0.97 for VSS-V, VSS?-?AA, and VSS?-?T, respectively.ConclusionGiven a critical shortage in PROMs for the vestibular field, the psychometric properties of VSS?-?SF?-?CK were evaluated. The results were promising, as they revealed external consistency and construct validity. The goodness of fit indices showed that the VSS?-?SF?-?CK is a reliable and validated PROM that can be used by clinicians and researchers in the Kurdish-speaking population.

Project description:BackgroundThe clinical relevance of resilience has received considerable attention in recent years. The aim of this study is to demonstrate the reliability and validity of the Japanese version of the Resilience Scale (RS) and short version of the RS (RS-14).FindingsThe original English version of RS was translated to Japanese and the Japanese version was confirmed by back-translation. Participants were 430 nursing and university psychology students. The RS, Center for Epidemiologic Studies Depression Scale (CES-D), Rosenberg Self-Esteem Scale (RSES), Social Support Questionnaire (SSQ), Perceived Stress Scale (PSS), and Sheehan Disability Scale (SDS) were administered. Internal consistency, convergent validity and factor loadings were assessed at initial assessment. Test-retest reliability was assessed using data collected from 107 students at 3 months after baseline. Mean score on the RS was 111.19. Cronbach's alpha coefficients for the RS and RS-14 were 0.90 and 0.88, respectively. The test-retest correlation coefficients for the RS and RS-14 were 0.83 and 0.84, respectively. Both the RS and RS-14 were negatively correlated with the CES-D and SDS, and positively correlated with the RSES, SSQ and PSS (all p < 0.05), although the correlation between the RS and CES-D was somewhat lower than that in previous studies. Factor analyses indicated a one-factor solution for RS-14, but as for RS, the result was not consistent with previous studies.ConclusionsThis study demonstrates that the Japanese version of RS has psychometric properties with high degrees of internal consistency, high test-retest reliability, and relatively low concurrent validity. RS-14 was equivalent to the RS in internal consistency, test-retest reliability, and concurrent validity. Low scores on the RS, a positive correlation between the RS and perceived stress, and a relatively low correlation between the RS and depressive symptoms in this study suggest that validity of the Japanese version of the RS might be relatively low compared with the original English version.
