Abstract
OBJECTIVE: The development of the International Classification of Impairments, Disabilities and Handicaps (ICIDH) has led to the assessment of a wider range of re evant rehabilitation outcomes, but a need for a further broadening exists. In this article, a new proposal for an extended ICIDH is made. METHOD: Review of the literature on quality of life and of attempts to integrate the World Health Organization (WHO) biopsychosocial model and the ICIDH. RESULTS: Our review shows three operationalizations of the concept of quality of life: as health, as well-being and, preferably, as a superordinate construct. None of the attempts to integrate the WHO biopsychosocial model have been entirely successful. Our new proposal is characterized by (a) incorporation of the organ, person and social levels of the ICIDH, (b) distinction between objective and subjective aspects of quality of life as a second axis in the model, resulting in somatic sensations as the subjective part of the organ level, perceived hea th as the subjective part of the person level and domain-specific life satisfaction as the subjective part of the social level, and (c) separation of the concept of general well-being or happiness as being distinct from the ICIDH. The proposal mode is intended to serve as a framework in which different outcomes can be positioned in relation to each other. CONCLUSION: Our model is intuitively appealing and remains close to familiar concepts and models. However, it is as yet far from perfect, and we hope to provoke discussion to help further refinement.
