Validation of the Beck Depression Inventory II in HIV-positive patients

Research on depression among HIV-positive patients has been limited by the lack of a valid and reliable measure of depression. This project addresses this problem by exploring the internal consistency reliability and the concurrent and discriminant validity of the Beck Depression Inventory-II (BDI-II) using HIV-positive patients in Jamaica.

Patients from three HIV clinics in Jamaica (n = 191 patients; 61% female, 39% male, mean age 40.5-10 years) were administered the BDI-II along with the Centre for Epidemiological Studies -Depression Scale (CES-D) and the Social Provisions Scale.

Overall, the BDI-II was found to have a high degree of reliability (alpha = 0.89). The scale also had good concurrent validity as evidenced by a high correlation with scores on the CES-D (r = 0.74) and acceptable discriminant validity as demonstrated through a moderate correlation with the Social Provisions Scale (r = -0.42). This pattern of scores suggests that the majority of the variance underlying the BDI-II assesses depression (55%) while a smaller degree of the variability (18%) measures a conceptually similar but distinct concept.

The BDI-II is a sufficiently reliable and valid measure for assessing depression in HIV-positive patients.
