ABSTRACT

Object: This study aimed to identify the methods and outcomes of occupation-based interventions as well as the dependent variables and assessment tools used in studies on occupation-based interventions for older adults. Methods: Studies were collected from the Scopus, PubMed, Embase, Web of Science, and RISS databases. There were no restrictions on study duration. Study selection followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and seven studies were included. Results: Of the seven included studies, three were randomized controlled trials, three were one-group non-randomized studies, and one was a single-case study. The most frequently assessed dependent variable in the selected studies was occupational performance, followed by a variety of other variables such as physical function, cognitive function, depression, and quality of life. The interventions showed significant improvements in various aspects, including occupational performance, quality of life, and reductions in depression. Conclusion: This study aimed to provide evidence and direction for the development of and research regarding occupation-based interventions for older adults. Future research should focus on high-quality studies and verify the effectiveness of occupation-based interventions on various aspects in older adults.
