Background: Family Quality of Life (FQOL) is an important construct in the Intellectual Disabilities field. Several measures exist, including one developed by an international group, the Family Quality of Life Survey-2006 (FQOLS-2006; Brown et al.2006). However, the psychometric properties of this measure have yet to be fully investigated. This study was designed to examine its concurrent validity compared to the well established Beach Center FQOL Scale. Materials and Methods: In a sample of 62 families of school-aged Canadian children with intellectual disability and/or autism spectrum disorder, both the FQOLS-2006 and the Beach Center FQOL scale were administered and the scores compared. Results: The total scores of the two measures were strongly correlated, as were particular subscales that would be expected to correlate. However, there were several surprising correlations as well. Conclusions: The FQOLS-2006 shows good concurrent validity relative to the Beach Center scale, although some domains show unexpected relationships, suggesting further research is needed.
