A preliminary review of the Beck Depression Inventory-II (BDI-II) in veterans: Are new norms and cut scores needed?

Abstract

The Beck Depression Inventory-II (BDI-II) is used within the Veterans Health Administration (VHA) to measure depression symptom severity. This naturalistic study aimed to examine VHA-specific BDI-II use and establish normative data and psychometric properties. Initial BDI-II data for 152,260 individual veterans were extracted from preexisting medical records using the VA Informatics and Computing Infrastructure. BDI-II scores were compared against Beck, Steer, and Brown (1996)'s original sample, as well as across veteran subgroups. Exploratory and confirmatory factor analyses were also conducted. Similar to Beck et al.'s (1996) sample, the BDI-II was most frequently administered in outpatient psychiatric VHA settings, although it was also used in inpatient and medical settings. Veterans scored significantly higher on the BDI-II than the original comparison groups. This was true across diagnostic categories. The largest discrepancy was seen between nondepressed veterans and corresponding patients from the original sample (Cohen's d = 1.34). Older veterans endorsed less severe levels of depression symptomatology. Additionally, a 2-factor model similar to Beck et al.'s (1996) original solution provided the best fit to the data. Veterans reported higher levels of somatic-affective symptoms than cognitive symptoms. Although potentially useful, the BDI-II requires further investigation in veterans. Standard cut scores are not recommended for use in this population when evaluating severity of depression. A cut score of 27 or higher best differentiated between veterans with and without mood disorders in the current sample. Treatment providers should also consider using BDI-II factor scores, rather than the total score, to measure depressive symptom change. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
