RESUMO
BACKGROUND: Cognitive degeneration and agitated behavior symptoms of dementia in older adults are the main causes of disability and inability and increase the cost of medical care. Agitated behavior symptoms of dementia are the main causes of early institutionalization and make caregivers exhausted. PURPOSE: The aim of this study was to examine the effects of art therapy and reminiscence therapy on the alleviation of agitated behaviors in older adults with dementia. METHODS: An experimental research design with two experimental groups and one comparison group was conducted to examine the effects for each group on agitated behaviors. Participants were recruited from two dementia care centers in central and northern Taiwan. The study included 54 older individuals who met the sampling criteria and completed the data collection process. The participants were randomly allocated into the art therapy group (n = 24), the reminiscence therapy group (n = 22), and the comparison group (n = 8). The intervention consisted of 50-minute sessions conducted weekly for 12 weeks. Regular activities were continued in the comparison group. The structured questionnaires were completed, and observations of agitated behaviors were collected before the intervention and at 1 and 6 weeks after the intervention. RESULTS: Significant differences were found in agitated behavior symptoms at the three time points in the art therapy group, whereas reminiscence therapy was found to have had a clear and immediate effect on decreasing agitated behavior. The generalized estimating equation exchange model test revealed a significant and sustained, postintervention effect of art therapy on agitated behavior. In contrast, no significant and sustained effect on agitated behavior was observed in the reminiscence therapy group. CONCLUSIONS: The findings of this study support that art therapy may have a positive effect on dementia-associated agitated behaviors in institutionalized older adults. Reminiscence therapy activities conducted weekly for 50 minutes each session did not reach statistically significant implications. It is suggested that future studies consider conducting art and reminiscence therapies for a 16-week duration with two weekly sessions to evaluate the effectiveness of the therapy. The duration of follow-up should be extended as well in future studies.
