Self-rated quality of life scales for people with an intellectual disability: A review

The quality of life construct is briefly reviewed. This is followed by a description of 13 scales that purport to measure the construct. Each scale is analysed in terms of its scope and psychometric properties. Two major conclusions are drawn. The first is that the two scales which seem to have most promise at this stage are the Quality of Life Questionnaire and the Comprehensive Quality of Life Scale. The second conclusion is that both scales require further development, most particularly to maintain their relevance as our understanding of the underlying construct and measurement issues evolves.
