title: Do Adult Attention Deficit Hyperactivity Disorder Quality-Of-Life (AAQoL) scale and the SF-36 scale measure the same construct of health-related quality of life?
abstract: It has never been investigated whether the assessment tools of Adult Attention Deficit Hyperactivity Disorder Quality-of-Life (AAQoL) scale and the SF-36 measure the same construct. The participants were 101 parents of children with ADHD and 243 parents of school children. The parents completed both the Persian version of the AAQoL and the SF-36 questionnaires. The present study revealed that the Persian version of both AAQoL and SF-36 for the assessment of HRQoL in parents of children with ADHD has convergent and discriminant validity and internal consistency. Multitrait-multimethod correlation matrix showed that the domains of two questionnaires were moderately correlated. Current results support that AAQoL and SF-36 in parents of children with ADHD measure the same HRQoL constructs. Hence, for assessing the HRQoL of parents of children with ADHD, one of the two questionnaires can be used regard to the objective of study. The Persian version of the AAQoL loaded on four domains which were in line with the original version. HRQoL of parents of children with ADHD is markedly less than the community sample of children.
