    Abstract

    To determine the relative validity of parent-assessed and self-assessed symptoms of Generalised Anxiety Disorder (GAD) in boys with an Autism Spectrum Disorder (ASD). 140 boys with an Autism Spectrum Disorder (ASD) were assessed for GAD by their parents and by themselves, and gave a sample of cortisol during the afternoon of these assessments. There were significant differences between self-assessments and parents’ assessments for the total GAD score and on four of the eight individual GAD symptoms. Using cortisol concentrations as a validation index, the two key GAD items were most validly assessed via boys’ self-ratings. Key GAD symptoms in boys with an ASD may be best assessed from their self-reports rather than by their parents’ reports. Implications for clinical practice are discussed.
