Abstract

Background: The construct of quality of life (QoL) has been the focus of a great deal of recent research and has been operationalized in the assessment of the effectiveness of biomedical and rehabilitative interventions. Consequently, the effective measurement of QoL has become a relevant issue. QoL assessment should take account of both objective life conditions and reported satisfaction with those conditions, and should recognize that QoL has multiple domains. There is also evidence to suggest that it is useful to supplement such assessments with the evaluations of significant others within a multidimensional assessment perspective. Methods: The current study describes a further stage of testing and refinement of the Evaluation of Quality of Life Instrument (EQLI), which was designed to elicit from staff of health and social care services assessments of the level of satisfaction experienced by adults with an intellectual disability. Specifically, the EQLI's internal consistency, and construct, convergent and discriminant validity were analysed. Results: The EQLI appears to be a psychometrically valid measure for collecting data on the levels of satisfaction which, according to health and social services staff, might be experienced by individuals with an intellectual disability who attend residential institutions and community-based day centres. The factor analyses supported a three-factor structure for the EQLI and reliability estimates of scores on the three factors were in the moderate to high range. The data collected supported convergent and discriminant validity. Conclusions: The results indicate that the EQLI is an effective measure for gaining staff perceptions of individuals who may be at risk of dissatisfaction with various QoL domains. The EQLI is as an instrument which, within a multidimensional assessment, could contribute to the identification of areas of user dissatisfaction with services.
