Abstract
Patient and staff behavior on a psychiatric hospital ward were assessed through behavioral observation. Twenty-four codes for patient behavior, 18 codes for ward locations, and two codes for staff behavior were used to analyze the activity of 30 dually- diagnosed (mentally retarded and mentally ill) patients. The results showed that patients spend much of their waking time unengaged in day rooms and halls. Staff spend the majority of their time in indirect care activities in a nursing station.
