Validity and test–retest reliability of the Persian version of the Montgomery–Asberg Depression Rating Scale

Background. The Barkley Adult Attention Deficit/Hyperactivity Disorder (ADHD) Rating Scale-IV (BAARS-IV) was developed, and it demonstrated good psychometric properties. The BAARS-IV includes 27 questions on the symptoms of adult ADHD. The purpose of the present study is to investigate the psychometric testing of the Persian version of BAARS-IV among the elderlies in Tabriz City. Method. This cross-sectional study was conducted in Tabriz City—in the west of Iran—in 2015 via enrolling of 121 old-aged people. We did the process of translation and adaptation of BAARS-IV and examined its concurrent validity, internal consistency, and test-retest reliability. Result. The BAARS-IV demonstrated good internal consistency and test-retest reliability. Correlations between the BAARS-IV and the CAARS-S: SV were high and evidence supporting concurrent validity was revealed. Cronbach’s alpha for the overall scale and subscales stood at 0.89, 0.81, 0.66, 0.56, and 0.82, respectively. Conclusion. The Persian BAARS-IV showed acceptable reliability and validity. BAARS-IV was determined to be composed of internally consistent and psychometrically sound items.

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.

Abstract Background Hemodialysis is considered a major therapeutic method for patients with chronic kidney disease. Pruritus is a common complaint of hemodialysis patients. The 5-D pruritus scale is amongst the most common tools to evaluate several dimensions of itch. Psychometric properties of the 5-D scale have not been evaluated in Persian speaking population with hemodialysis; hence, the objective of this study was to assess reliability and validity of the Persian version of the scale. Methods Ninety hemodialysis patients (men: 50, women: 40, mean age: 54.4 years) participated in this cross-sectional study. The final Persian version of 5-D scale was given to the participants. Tests Compared: One-third of the participants completed the scale twice within 3–7 days apart to evaluate test- retest reliability. Other psychometric properties including internal consistency, absolute reliability, convergent, discriminative and construct validity, floor/ceiling effects were also evaluated. Results The Persian 5-D scale has strong test-retest reliability (ICC= 0.98) and internal consistency (Cronbach’s alpha= 0.99). Standard error of measurement and minimal detectable change were 0.33 and 0.91, respectively. Regarding convergent validity, the scale had moderate correlation with numeric rating scale (r =0.67) and quality of life questionnaire related to itch (r = 0.59). Exploratory factor analysis revealed two factors within the scale. No floor or ceiling effect was found for the scale. Conclusion The Persian version of 5-D the itching scale is a brief instrument with acceptable reliability and validity. Therefore, the scale could be used by experts, nurses, and other health service providers to evaluate pruritus among Persian speaking hemodialysis patients.

Background: This study aimed to translate and validate the Fear of Cancer Recurrence Inventory (FCRI) questionnaire into Persian and to investigate its psychometric properties. Methods: The FCRI was translated to Persian using a linguistic methodology according to WHO guidelines. A total of 450 breast cancer survivors who had the following inclusion criteria were included: time elapse of more than six months after the treatment prior to the study; absence ofobjective markers of recurrence, fluency in the Persian language, and signing the informed consent. Internal consistency was estimated with Cronbach's α coefficient and test-retest reliability with Interclass correlation. Concurrent validity was estimated through Pearson’s correlation between the FCRI and Hospital Anxiety and Depression Scale (HADS). Principal component analysis (PCA) and confirmatory factor analysis (CFA) were employed to evaluate dimensionality. Results: The Persian version was acceptable for patients. The content validity index (CVI) was 0.80. The instrument had good test-retest reliability (ICC= 0.96) and internal consistency (Cronbach’s α=0.86). PCA and CFA indicated that the factor structure of the Persian version was similar to the original questionnaire and had acceptable goodness of fit. Correlations between the FCRI and HADS was remarkable (r= 0.252 – 0.639), indicating acceptable concurrent validity. Conclusions: The Persian version of FCRI could be considered a good cross-cultural equivalent for the original English version. The questionnaire was a reliable and valid instrument in terms of internal consistency, test-retest reliability, and dimensionality.

ABSTRACTAdaptive behaviour scales represent an alternative to standardised intelligence tests for assessing children with multiple disabilities. The purpose of the present study was to evaluate the reliability of an adaptive behaviour scale used in Hungarian Conductive Education programs for children with neurological impairments. Forty-five children with multiple disabilities were assessed on two separate occasions by their teachers and physiotherapists. Scores were compared across raters (interobserver agreement) and across the two assessment occasions (test-retest reliability). Interobserver agreement averaged 55.5%, and the overall test-retest reliability was 75%. Suggestions for improving interobserver agreement and test-retest reliability are discussed.

ObjectivesThis study aimed to translate, cross-culturally adapt and psychometrically validate a Persian version of the Cardiac Rehabilitation Barriers Scale (CRBS-P) and to identify the main barriers in an Iranian setting.SettingAfshar cardiac rehabilitation (CR) centre, affiliated with the Yazd University of Medical Sciences, in the centre of Iran.DesignThis was a multimethod study, culminating in a cross-sectional survey.ParticipantsInpatient CR graduates who did not attend their initial outpatient CR appointment.MethodThe 21-item CRBS was translated and cross-culturally adapted in accordance with best practices; an expert panel considered the items and previous non-attending patients were interviewed via phone to refine the scale. Next, structural validity was assessed; participants were invited to complete the CRBS on the phone between March 2017 and February 2018. Using exploratory factor analysis (EFA) with principal component analysis extraction and oblique rotation. Second, confirmatory factor analysis (CFA) was used to verify the results; several goodness-of-fit indices were considered. The internal consistency and 3-week test–retest reliability of the scale (5% subsample) were evaluated using Cronbach’s α and intraclass correlation (ICC), respectively.ResultsFace, content and cross-cultural validity were established by the experts and patients (n=50). One thousand and one hundred (40.7%) of the 2700 patients completed the CRBS-P. Structural validity was established by EFA (Bartlett’s test p<0.001; =0.759) and confirmed by the CFA; a four-factor solution with 18 items accounting for 61.256% of variance had the best fit (χ2/df=3.206, root mean square error of approximation=0.061 and Comparative Fit Index=0.959). The internal consistency and test–retest reliability (n=42) of the scale were acceptable (ICC=0.743 95% CI (0.502 to 0.868); overall α=0.797). The top barriers were not knowing about CR, cost and lack of encouragement from physicians.ConclusionThe four-factor, 18-item CRBS-P had good psychometric properties, and hence can be reliably and validly used to measure CR barriers in Iran and other Persian-speaking populations.
