The concept of quality of life is increasingly being used internationally in the field of intellectual disabilities. We surveyed three respondent groups representing five geographical groupings on the importance and use of the 24 core quality of life indicators most commonly reported in the international quality of life literature. Results suggest (a) similar profiles on importance and use across respondent and geographical groups, but differences in the frequency per response category; (b) significant differences in mean quality of life importance and use scores for both respondent and geographic groupings; and (c) factors on importance and use generally grouped into eight core quality of life domains. Results are discussed in reference to the etic (universal) and emic (culture-bound) properties of the quality of life concept.
The concept of quality of life currently impacts program development, service delivery, management strategies, and outcome evaluation in the area of intellectual disabilities. Maryland uses peer interviewers to assess consumer-perceived quality of life among adult recipients of MR/DD services and supports. In this article we describe the survey instrument and procedures and discuss assessment issues of quality of responses, acquiescence, and proxy respondents. We present the psychometric properties for eight core quality of life domains among 923 people assessed in FY 2001. Results are summarized and development of a model for enhancing social inclusion, personal development, and self-determination was described. Service and personal characteristics relating to quality of life as well as some ways the results can be used for program enhancement are discussed.
A systematic approach for addressing the support needs of persons with mental retardation and related developmental disabilities is presented and a new scale to measure individual differences in support needs described. The process employed in developing the scale is explained, including the establishment of a typology of support areas that was drawn from a review of the professional literature, a validation process using Q-sort methodology, and a pilot field test. Critical issues and practical challenges associated with efforts to measure and address the support needs of individuals are discussed.
In this article a number of issues involving the concept of quality of life as applied to persons with intellectual disabilities are summarized, and a number of agreed-upon principles regarding its conceptualization, measurement, and application are presented. We realize that the concepts and models presented in this article will vary potentially from country to country, and even from area to area within countries. The cross-cultural understanding of the concept of quality of life is in its infancy, and we hope that the discourses resulting from the material presented in this article will facilitate both cross-cultural understanding and collaborative work. The article reflects current thought about the conceptualization, measurement, and application of this increasingly important and widely used concept in the field of intellectual disabilities and sets the stage for its continuing development.
