Psychometric properties of a Persian-language version of the Beck Depression Inventory - Second edition: BDI-II-PERSIAN

Abstract

The Beck Depression Inventory (BDI) is perhaps the most commonly used screening instrument for depression in the general population. We examined the psychometric properties of a Persian-language version of the second edition of this instrument (BDI-II) [Beck et al., 1996] in an Iranian college-student sample. In a sample of 125 student volunteers from two Iranian universities, we compared mean item scores on the BDI-II-Persian with those on the English-language version administered to North American college students, and assessed internal consistency and test-retest reliability of the BDI-II-Persian and its concurrent validity against a measure of negative automatic thoughts in depression, the Automatic Thoughts Questionnaire [Hollon and Kendall, 1980]. We also examined the factor structure of the BDI-II-Persian through comparing the fit of various proposed models to the data using confirmatory factor analysis. The BDI-II-Persian had high internal consistency (Cronbach's alpha=0.87) and acceptable test-retest reliability (r=0.74). The instrument correlated strongly with the Automatic Thoughts Questionnaire. In factor analysis, models with strongly correlated affective-cognitive and somatic-vegetative factors provided a better fit than models with one global factor. These data support the reliability and concurrent validity of the BDI-II-Persian as a measure of depressive symptoms in nonclinical samples.

“…According to the cut-off scores, the patients were classified into minimal, mild, moderate, and severe depression groups (20). The Persian version of the questionnaire has been validated (21), and its internal reliability was found to be acceptable in the present study (Cronbach's α, 0.89).…”

“…Patients also completed a series of questionnaires. The 21--item self-report Beck Depression Inventory (BDI) whose validity and reliability has been previously approved in Iran [17,18] was used to assess the then current depressive symptoms. Scores of 10 or higher were considered to indicate the presence of mild to severe symptoms of depression [19].…”

“…Furthermore, to verify if the patients had any language related deficits that could affect their performances at the FE tasks especially the recognition task participants also completed the verbal fluency part of the Persian version of MoCA test [26][27][28].…”
