This study was conducted to examine the ADL and life satisfaction of the physically disabled at home and to look at their interrelationship and the factors that affect them. Methods : The subjects of this study were 102 physically disabled people staying at home who were aged 20 or older. Their ADL and life ssatisfaction were measured using K-ADL and K-IADL, and a life satisfaction scale, respectively. Results : First, the subjects had overall low ADL and life satisfaction levels. Second, the correlation among KADL, K-IADL, and life satisfaction were significant, with the exception of the correlation between K-ADL and life satisfaction. In particular, their life satisfaction had a more significant correlation with their K-IADL than their K-ADL. Third, the examination of factors affecting their life satisfaction showed that mobility and the use of transportation influenced their life satisfaction. Conclusion : Intervention with I-ADL rather than B-ADL is considered to be necessary to enhance the life satisfaction of the physically disabled at home.
