Stress and distress in New Zealand parents caring for a child with autism spectrum disorder.

The aim of this cross-sectional study was to identify predictors of the mental health of parents of a child with autism spectrum disorder (ASD). A convenience sample of 658 parents residing in New Zealand completed an online questionnaire. Participants responded to questions probing parent and child characteristics, child ASD severity (the Autism Impact Measure: AIM), parenting stress (the Autism Parenting Stress Index: APSI), and parent mental health (the General Health Questionnaire: GHQ-28). The results indicated that the majority of the parents in our sample have reached clinical levels of psychiatric distress, in particular anxiety. Parent and child characteristics were poor predictors of parental mental health problems. Parenting stress, however, was found to be a significant predictor, also acting as a mediator variable between child ASD symptom severity and parental mental health problems. Our findings are interpreted in relation to their significance to clinical practice.
