Understanding quality of life of persons with profound intellectual and multiple disabilities

In this paper, we discuss the applicability of the consensus document, prepared by the Special Interest Research Group on quality of life (QoL) of the International Association for the Scientific Study of Intellectual Disabilities in August 2000, for persons with Profound Intellectual and Multiple disabilities (PIMD). We compare our findings from previous empirical research with some elements of the themes and principles of the consensus document. We will reflect (1) on the domains of QoL mentioned in the consensus document, and (2) on the assessment by proxies. We recommend reflection on the following aspects when composing a new consensus document, which includes QoL of persons with PIMD: first, reconsider whether all eight domains are useful in care practice for—and research about—persons with PIMD. We assert that the domains of health, well-being, capability to influence the environment, and also (family) relationships, are particularly relevant for the QoL of persons with PIMD and, second, accept interpretation of signals and signs by proxies in the assessment of QoL in persons with PIMD and do not value this as second best.
