Clinical observation had suggested that mild depression occurs after admission for acute medical treatment and then decreases during further hospitalization for rehabilitation treatment. The Geriatric Depression Scale (GDS) was given on admission and discharge to 14 stroke and 17 amputee rehabilitation patients. Each of the two groups showed decreasing GDS scores from beginning to end of the rehabilitation admission. Suggested reasons included: (1) the gradually diminishing effects of stroke and amputation as life crises during the 1-2 month admission, (2) effects of physical improvement on mood and affect, (3) milieu effects of the medical ward, and (4) tendencies for all psychopathology scale scores to decrease on retest.
