This study was designed to obtain objective results about the effects of two different parent-child activities on the siblings of children with autism. Participants were eighteen 6-13 year-old siblings of children with autism and their parents. One group of parent-child pairs completed a workbook focused on autism-specific worries, while another group of parent-child pairs played board games together. The children in each group completed a questionnaire about their autism-related worries at the end of the activity. Results demonstrated that the workbook was useful in making parents more aware of specific worries that their children have as shown by a strong correlation between child report of worries and parent report of child's worries.
