Predictors of life satisfaction in individuals with intellectual disabilities

The purpose of this study was to examine factors that predict life satisfaction in individuals with intellectual disabilities (ID). Two groups of variables were studied: life skills (interpersonal, instrumental and leisure) and higher-order predictors (social support, self-determination and productivity). Fifty-six participants with ID were recruited from two community agencies in Wisconsin. Data were collected using both a self-report inventory, which was administered to each individual in an interview format, and a behaviour rating scale, which was completed by a knowledgeable staff member. Hierarchical regression was used to analyse the data. Both sets of variables were found to explain a significant amount of the variance in life satisfaction. Within the sets, social support and interpersonal skills were individually significantly associated with life satisfaction. It is hoped that the results of this study will help support providers organise services in such a way that maximises the life satisfaction of the consumers that they serve.
