title: Effect of developmental quotient on symptoms of inattention and impulsivity among toddlers with Autism Spectrum Disorders.
abstract: The effect of developmental quotient on symptoms of inattention and impulsivity was examined among 198 toddlers with Autism Spectrum Disorders. There were two levels of developmental quotient: (1) low (less than or equal to 70; n=80), and (2) typical (greater than 70; n=118). Symptoms of inattention and impulsivity were assessed using 14 items that comprise the BISCIUT-Part 2 inattention/impulsivity subscale. There was no significant effect of developmental quotient on these items representing inattention and impulsivity when severity of Autism Spectrum Disorder symptoms was controlled for. However, the covariate, severity of Autism Spectrum Disorder symptoms, was significantly related to 12 of the 14 items. Percent endorsement of impairment of symptoms relating to inattention and impulsivity for the low and typical developmental quotient groups is also listed. Implications of the results are also discussed.
