This systematic review describes the benefits of individualized leisure and social activity interventions for people with dementia (aim 1), how these interventions were individually tailored (aim 2), and what recommendations or suggestions can be made for these interventions and further studies (aim 3). Thirty-two included studies were organized into four categories based on how the intervention was individually tailored. These categories include: (1) performance factors; (2) self-identity; (3) music preference; and (4) life experiences and past memories. The authors discuss suggestions and benefits by synthesizing the finding of the included studies in each category.
