Sheikh and Yesavage proposed an abbreviated version of the GDS to reduce problems of fatigue, especially among physically ill or demented patients (10). The 15 items are identified in the exhibit and take five to seven minutes to complete. Scores can be prorated to compensate for unanswered questions: (score × 15) / number of questions answered. Scores between 0 and 4 are considered normal, 5 to 9 indicate mild depression, and 10 to 15 indicate moderate-tosevere depression (3). Several authors have reported correlations between scores on the short and long forms: 0.84 (10, p169), 0.89 (11), and 0.66 in a sample of 81 without severely depressed patients (3).
