Comparison of the strengths and difficulties questionnaire (SDQ) scores between children with high-functioning autism spectrum disorder (HFASD) and attention-deficit/hyperactivity disorder (AD/HD)

The aim of this research was to compare the Strengths and Difficulties Questionnaire (SDQ) scores and subscale scores in children with high-functioning autism spectrum disorder (HFASD) and attention-deficit/hyperactivity disorder (AD/HD), and also to clarify the differences between parent- and teacher-assessed SDQ scores/subscores in HFASD and AD/HD children. These patients’ total difficulties scores were significantly high compared to the community sample. In the parent rating, HFASD children had significantly higher scores in the subscales of emotional symptoms and peer problems. In the teacher rating, AD/HD children showed significantly higher scores in the subscales of hyperactivity/inattention and conduct problems, whereas peer problems were significantly higher in HFASD. The teacher rating showed significantly greater difficulties than the parent rating on the subscale of prosocial behavior in both the AD/HD and HFASD groups. These results suggest that each subscale may reflect behavioral, emotional, and social characteristics of HFASD and AD/HD.
