Falls pose a significant health risk for nursing home residents and are associated with depression and medical treatments for depression. Data on falls as an adverse event to psychosocial treatments are lacking. We examined risk of falls as an adverse event in a clinical trial of a behavioral treatment for depression. Participants were 82 depressed nursing home residents. Adverse events were recorded at each research contact. We used the rate ratio based on the respective incidence densities in the treatment and control groups to measure association between fall rate and treatment. The treatment group had almost six times higher risk of falls than the control group, a statistically significant association. Findings suggest that it may be of value to include statistical analysis of falls as adverse events in trials of behavioral interventions for depression.
