Because there are unique challenges in raising a child with Autistic Spectrum Disorder (ASD), parents are likely to suffer from emotional difficulties, such as stress and depression. Specifically, maternal depression correlates with problem behavior in developmentally delayed children and parenting stress covaries with sensory, motor, and executive impairments in children with ASD. Furthermore, parenting stress is an important issue for ASD interventions because it reduces therapeutic gains and progress. However, social support and psychoeducation buffer emotional difficulties in parents of children with ASD. Sensory integration therapy targets sensory and motor impairments and provides parents with social support and ASD psychoeducation. As a result, we hypothesize that 1. sensory integration therapy will decrease parenting stress and depression, 2. maladaptive behavioral disturbances in children with ASD will increase parenting stress and depression, and 3. sensory integration therapy will decrease maladaptive behavioral disturbances in children with ASD.
