General Description

The QOL-Q was designed for people with intellectual disabilities and It consists of 40 items scored with a 1 to 3 points rating scale. Exploratory factor analysis of the Portuguese version of the QOL-Q indicated the existence of four factors, which include 30 items, and that were also supported by confirmatory factor analysis. The total score of the QOL-Q also revealed a moderate correlation with the self-concept.
