Aggressive behavior in hospitalized psychogeriatric patients.

The frequency and characteristics of aggressive and hostile behavior in 40 psychogeriatric inpatients was investigated using the Staff Observation Aggression Scale (SOAS). Most aggressive acts were directed towards nursing staff when providing help with activities of daily living. A positive correlation was found between age and the frequency of aggressive behavior, while severity was most strongly correlated to length of admission. A significant decrease in frequency was observed during the six weeks of observation. The causes of this decrease are discussed together with the implications for future studies on the treatment of aggressive behavior in this group of patients.
