Beck Depression Inventory II: evaluation of the psychometric properties and cut-off points in a Turkish adult population

Abstract

Numerous studies have been previously conducted to assess the Beck Depression Inventory-II's [BDI II; Beck et al., 1996] psychometric properties. However, none of these studies has examined whether the original cut-off scores were applicable to other cultures. Thus, in addition to evaluating its psychometric properties, we also determined the cut-off scores of the BDI II for the Turkish population. Data from nonclinical (n = 362) and clinical psychiatric outpatients diagnosed as depressive disorder according to DSM-IV criteria (n = 176) were gathered. Analyses for internal consistency and test-retest reliabilities and for convergent and discriminant validities were computed. Two confirmatory factor analyses, one derived from the present exploratory factor analyses and the other proposed in the original study were conducted for both groups. A receiver operating characteristics curve was utilized to determine the cut-off scores for the Turkish population revealing 0-12 for minimal, 13-18 for mild, 19-28 for moderate and 29-63 for severe depression. The internal consistency for the nonclinical and clinical groups were .90 and .89, respectively; test-retest stability was also high (r = .94). Convergent and discriminant validity results were satisfactory. Findings confirmed the present model for the clinical group and equally confirmed both models for the nonclinical group. Furthermore, the cut-off scores to classify minimal, mild, moderate, and severe depression were quite akin to the cut-off points previously suggested for the American population. Taken as a whole our findings revealed that BDI II has sound psychometric properties and comparable cut-off scores for the Turkish population.

“…[12] A BDI score of 21 has been suggested as a cut-off value for the diagnosis of depression in a Korean population. [14] The validation and reliability study in a Turkish population was made by Kapci et al, [15] and a BDI score of 17 or greater was a cut-off value for diagnosis of depression.…”

Cognitive Complaints in Patients with Fibromyalgia Versus Older-Aged Women: Case Control Study

“…However, according to many studies this demonstrable cognitive dysfunction in patients with FM cannot be attributed solely to co-occurring psychiatric disorders such as depression, and that it is related with pain, fatigue and many to the impact that pain has on a patient [24]. According to study evaluating the psychometric properties and cut-off points of Beck Depression Inventory Scale for Turkish population, authors have determined the cut-off scores for the Turkish population revealing 0-12 for minimal, 13-18 for mild, 19-28 for moderate and 29-63 for severe depression [17]. And in our study we have found that in both groups total scores of BDI revealed mild depression.…”

“…A lower total score indicates less effect of fatigue on everyday life [16]. Depressive symptoms in all of the groups were obtained from the Beck Depression Inventory (BDI) [17]. It consists of 21 groups of items that assess both cognitive/affective and vegetative signs of depression.…”
