As several rating scales have been used to assess depression in PD (dPD), the Movement Disorder Society commissioned a task force to assess their clinimetric properties and make clinical recommendations regarding their use. However, depression can be difficult to assess in patients with PD due to overlapping symptoms and difficulties in the assessment of depression in cognitively impaired patients. © 2007 Wiley-Liss, Inc.ĭepression is a common comorbid condition in Parkinson's disease (PD) and a major contributor to poor quality of life and disability. Taken as a whole our findings revealed that BDI II has sound psychometric properties and comparable cut-off scores for the Turkish population. 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. Findings confirmed the present model for the clinical group and equally confirmed both models for the nonclinical group. Convergent and discriminant validity results were satisfactory. 89, respectively test–retest stability was also high (r =. The internal consistency for the nonclinical and clinical groups were. 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. 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. Analyses for internal consistency and test–retest reliabilities and for convergent and discriminant validities were computed. Data from nonclinical (n = 362) and clinical psychiatric outpatients diagnosed as depressive disorder according to DSM-IV criteria (n = 176) were gathered. Thus, in addition to evaluating its psychometric properties, we also determined the cut-off scores of the BDI II for the Turkish population.
However, none of these studies has examined whether the original cut-off scores were applicable to other cultures. Numerous studies have been previously conducted to assess the Beck Depression Inventory-II's psychometric properties.

Although this scale represents a sound path for detecting depression in patients with medical conditions, the clinician should seek evidence for how to interpret the score before using the Beck Depression Inventory-II to make clinical decisions. The Beck Depression Inventory-II can be easily adapted in most clinical conditions for detecting major depression and recommending an appropriate intervention. The somatic and cognitive-affective dimension described the latent structure of the instrument. Its threshold for detecting depression varied according to the type of patients, suggesting the need for adjusted cutoff points. The Beck Depression Inventory-II showed high reliability and good correlation with measures of depression and anxiety. Validation studies of the Beck Depression Inventory-II, in both primary care and hospital settings, were found for clinics of cardiology, neurology, obstetrics, brain injury, nephrology, chronic pain, chronic fatigue, oncology, and infectious disease. Considering the inclusion and exclusion criteria seventy articles were retained. We examined relevant investigations with the Beck Depression Inventory-II for measuring depression in medical settings to provide guidelines for practicing clinicians. To perform a systematic review of the utility of the Beck Depression Inventory for detecting depression in medical settings, this article focuses on the revised version of the scale (Beck Depression Inventory-II), which was reformulated according to the DSM-IV criteria for major depression.
