Abstract

Comparative validity and reliability study of the QIDS-SR16 in Turkish and American college student samples Objective: To evaluate the validity and reliability of the Quick Inventory of Depressive Symptomatology, selfreported version, in a Turkish student sample (QIDS-SR16-T) by comparing it to (a) the American version (QIDS-SR16- US) and (b) the Turkish version of the Beck Depression Inventory (BDI-II-T). Materials and Methods: Slightly modified versions of the QIDS-SR16-T, and the BDI-II-T were administered to 626 outpatients at the Uludaǧ University campus-based family health center. The QIDS-SR16-US was administered to 584 respondents at an American university. SAS and MPlus were used to provide descriptive statistics, classical exploratory factor analysis, and item response theory analyses (in the form of a multiple group confirmatory factor analysis). Results: The internal consistency (Cronbach α) of the QIDS-SR16-T was 0.77. Both QIDS-SR16 versions were unidimensional, but the BDI-II-T was not. The mean QIDSSR16- T and QIDS-SR16-US item-total correlations were similar. The correlation between the QIDS-SR16-T and BDIII- T was 0.72 (.90 when disattenuated). Multiple-group confirmatory factor analysis suggested that the QIDSSR16- T and QIDS-SR16-US had the same factor loadings but different intercepts. This reflects group differences in level of depression, perhaps because the Turkish respondents, unlike their US counterparts, were seen in a medical context where illness-related depression is more prevalent. Scores on the QIDS-SR16-T and the BDI-II-T were also equated. Discussion: The QIDS-SR16-T has good psychometric properties and convergent validity with the BDI-II-T. Its use is recommended when a self-reported instrument is appropriate.
