Reliability and validity of the short form Beck Depression Inventory with older adults.

This study investigated the reliability and validity of the short form Beck Depression Inventory with older adults. Sixty-one clinically depressed older outpatients and 57 non-patient older volunteers comprised the sample. The patient group completed the BDI prior to and at completion of depression treatment. Estimates of internal reliability suggest that the short form BDI possesses adequate Spearman-Brown and alpha coefficients. Congruent validity estimates were less satisfactory, as the correlation between the BDI and the HRSD was statistically significant, but low. Criterion group validity, diagnostic sensitivity, and sensitivity to change estimates were all acceptable. Thus, the short form BDI is adequately reliable to suggest its use as a research and clinical tool with older adults, although further study of the instrument's validity is needed.
