Abstract

The Geriatric Depression Scale (GDS) is one of the most widely used self-rated mood questionnaires for older adults. It is highly correlated with clinical diagnoses of depression and has demonstrated validity across different patient populations. However, the reliability of the GDS among African American older adults remains to be firmly established. In a baseline sample of 401 African American adults age 51 and over, the GDS-15 item short form demonstrates good internal consistency (KR20=.71). Stability over a 15-month interval in a retest sample of 51 adults is deemed adequate (r=.68). These findings support the use of the GDS-15 item short form as a reliable mood questionnaire among African American older adults.
