Beck Depression Inventory (BDI)
The Beck Depression Inventory is a 21-item multiple choice self-report inventory widely used measure of the presence and degree of depression in adolescents and adults.
The most recent version is the Beck Depression Inventory®-II (BDI®-II), constructed by Aaron T. Beck and colleagues (Beck et al. 1996a). The BDI®-II can be self-administered or verbally by a trained administrator, is validated for completion by 13- to 80-year-old individuals, and is available from http://www.pearsonassessments.com/HAIWEB/Cultures/en-us/Productdetail.htm?Pid=015-8018-370&Mode=summary. It has high test-retest reliability (Pearson r = 0.93) (Beck et al. 1996b). It also has high internal consistency (Alpha 0.91) (Beck et al. 1996a).
The BDI includes both cognitive and somatic symptoms of depression, unlike the Hospital Anxiety and Depression Scale which was developed for use with somatic illness patients, and therefore excludes somatic symptoms of depression to reduce confounding. The inclusion of somatic symptoms in the BDI enables the user to identify different types of depression in individuals (Canals et al. 2001).
