In this randomized study, we compared the psychological well-being of elderly nursing home residents who participated in reminiscence and current topics group discussions with a control group of residents. We rated participants happiness/depression, activity, mood, and functional levels before and after the group interventions. The intervention had a significant effect only on the happiness/depression measure, with both intervention groups showing positive changes compared to the control group.
