Abstract

The aim of this study was to assess the psychometric properties of the Comprehensive Quality of Life Scale, Objective Version. Content validity was obtained using Aiken’s V coefficient with the participation of 10 experts and inter-rater reliability was assessed with a sample of 45 participants from 15 families with presence of an intellectual disabled. The results showed insufficient validity in the criteria of clarity, consistency and relevance. The inter-observer reliability was moderate with an overall coefficient of .58. A new version of the scale was obtained for intellectual disabled persons, adapted to the sociocultural characteristics of Lima, Perú.
