Impact of Person-Environment-Occupation-Performance Model-Based Home-Visit Rehabilitation on Executive Function,...

Community-dwelling individuals with disabilities often face challenges in executive function, instrumental activities of daily living (IADLs), occupational performance, and quality of life. Home-visit rehabilitation based on the Person-Environment-Occupation-Performance (PEOP) model may address these challenges.

This study aimed to investigate the impact of a PEOP model-based home-visit rehabilitation program on executive function, IADLs, occupational performance, and quality of life among community-dwelling individuals with disabilities, and to examine whether these effects were sustained over time.

A single-group pre-, post-, and follow-up design was used with 13 community-dwelling individuals enrolled in a public health center rehabilitation program. Each participant was supported by three to four undergraduate occupational therapy students, who conducted assessments and interventions under the supervision of a licensed occupational therapist and an occupational therapy professor. The 10-week program included one pre-assessment, eight intervention sessions, and one post-assessment. Additionally, one follow-up assessment was conducted after 3 months of program completion, and 11 participants completed this follow-up. Outcomes were measured using the Executive Function Performance Test-Korean version for executive function and IADLs, the Canadian Occupational Performance Measure (COPM) for occupational performance, and the Korean Version of the World Health Organization Quality of Life (brief version) for quality of life.

Executive function and IADLs improved in organization, sequencing, completion, simple cooking and total scores from pre- to post-intervention, and in sequencing, simple cooking, telephone, paying bills and total scores from pre-intervention to follow-up. Occupational performance significantly enhanced pre-post and the significant effect on performance was still observed at follow-up. Quality of life significantly improved in the psychological domain from pre- to post-intervention, and in total scores from both pre-intervention to follow-up and post-intervention to follow-up.

PEOP-based home-visit rehabilitation improved executive function, IADL performance, occupational performance and quality of life in community-dwelling individuals with disabilities. Improvements in executive function and IADLs were sustained at follow-up, supporting the clinical value of evidence-based, PEOP-informed interventions.
