Review of 41 scientific studies conducted measuring the effectiveness of non-pharmacological interventions in managing aggressive behavior of elderly residents in long-term care facilities. Found that Sixty-six percent (27/41) of the studies report either a statistically or behaviorally significant reduction of aggressive behavior as a result of a non-pharmacological intervention. Staff training programs and environmental modifications appear to be the most effective strategies. Conclusion: Non-pharmacological interventions seem effective for managing aggressive elderly behavior.
