Influence of Activities of Daily Living on Quality of Life in Disabled Adults With Traumatic Brain Injury

This study aimed to examine the influence of activities of daily living on quality of life in disabled adults with traumatic brain injury. The study utilized raw data from the 2017 National Survey of Disabled Persons. From 6,549 individuals with disabilities, 46 adults aged ≥19 years with traumatic brain injury were selected as participants. Measurements included six sociodemographic characteristics, 12 domains of basic activities of daily living, eight domains of instrumental activities of daily living, and quality of life assessed using the EuroQol-5 Dimension (EQ-5D). The dependent variable was the total EQ-5D score, while the independent variables comprised sub-domains of basic activities of daily living (Model 1) and instrumental activities of daily living (Model 2). Model 3 included all variables except etiology. Stepwise multiple regression analysis was employed for statistical analysis. In Model 1, dressing (p=.004) and transfer (p=.005) affected EQ-5D (R²=.760). In Model 2, public transportation use (p<.001) affected EQ-5D (R²= .695). In Model 3 (R²=.809), factors affecting EQ-5D were dressing (p=.015), transfer (p=.002), disability grade (p=.042), and onset duration (p=.045). These findings suggest that occupational therapists should consider disability grade and onset duration when designing interventions to enhance activities of daily living in disabled adults with traumatic brain injury. Intervention programs should prioritize improving dressing, transfer, and public transportation use to promote a better quality of life in this population.
