Assessment of participation in people with a mild intellectual disability
Abstract: The overall aim of this doctoral thesis was to explore an assessment of participation according to the International Classification of Functioning, Disability and Health (ICF) in people with a mild intellectual disability.Study I used secondary data and explored how participation can be assessed. Study II-IV explored participation empirically regarding 68 everyday activities from all nine life domains according to the ICF. Study II explored assessment of self-rated participation by investigating to what extent perceived ability, actual performance and perceived importance correlated. Study III-IV explored the contribution of perceived importance to an assessment of participation; study III by investigating frequencies of everyday activities regarding performance and importance separately as well as regarding combined measures of performance and perceived importance, and study IV by comparing proxy ratings with self-rated measures regarding ability and measures of participation. Study III also correlated measures of participation with a single-item measure of subjective general well-being and study II and IV investigated internal consistency in terms of Cronbach’s alpha. Study II and III included 55 and 69 individuals with intellectual disability respectively. Study IV included 40 individuals with intellectual disability and 40 proxy persons. The informants from the target group were partly the same.Study II and IV supported the suggestions from study I that participation should be assessed by self-ratings and study II found that this is an appropriate method also to people with a mild intellectual disability. Study III showed that participation is related to subjective well-being. Study III-IV found somewhat different results if measuring participation as performance solely or as a combination of performance and perceived importance. Overall, the results of the thesis suggest that performance solely might be sufficient to assess participation at a group level but in a clinical context, when the knowledge of a certain individual is of interest, the perceived aspect of involvement is necessary to include in an assessment of participation.
