Abstract

Introduction: A growing body of evidence suggests that symptoms of attention-deficit/hyperactivity disorder (ADHD) persist into adulthood and are associated with ongoing impairment and co-morbidity. The absence of a conceptually sound and well-validated ADHD-specific quality-of-life measure has been an obstacle to understanding this impact. To address this gap, the Adult ADHD Quality-of-Life Scale (AAQoL) was developed based on well accepted methods for designing patient reported outcomes. The purpose of this study was to validate the AAQoL. Methods: Nine Hundred and Eighty Nine adults in a retrospective cohort study were administered the AAQoL and psychometric validation was conducted according to an a priori statistical analysis plan. Results: A 29-item AAQoL was found to have robust scale structure with four domains: Life Productivity, Psychological Health, Relationships and Life outlook. Internal consistency was adequate (0.93 for overall, 0.75–0.93 for subscales), and construct and known-groups validity were supported. Conclusion: The AAQoL appears to be a valid measure of quality of life for adults with ADHD and can be considered for incorporation into future studies. The ability to quantify the quality-of-life consequences of adult ADHD should facilitate future research, assist clinicians in identifying appropriate treatment targets and contribute to the ultimate goal of improving the well-being and functioning of adults with ADHD.
