S.I. : Parenting Children with ASD


The potential clinical needs of typically developing (TD) siblings of youth with autism spectrum disorder (ASD) remain disputed. A total of 239 mothers of youth aged 6–17, including one youth with ASD (M = 11.14 years; simplex families) and at least one other youth (M = 11.74 years) completed online standardized measures of various familial factors and TD youth outcomes. Overall, only 6–23% of siblings were identified within the clinical range of emotional, behavioral, or social functioning. Both maternal depression and sibling relationship were identified as key pathways in predicting siblings’ functioning within a good-fitting path analysis model. The current model is presented as a novel base for the development of future research and services for this unique population of children.

The present study was funded by a grant from the Autism Research Institute (#49071) and Dr. Stephen M. Edelson is thanked tremendously for his support. Collaboration with the Simons Simplex Collection via the Simons Foundation Autism Research Initiative was also invaluable to the present study. The authors would like to acknowledge Drs. Daniel O’Leary, John Robinson, and Julie Wolf for their invaluable feedback on earlier stages of this project. The following research assistants are also thanked: Lindsay Bungert, Andrea Charidemou, Sora Chenet, Dhara Doshi, Sruthi Jonnalagadda, Patricia Medina, Vladimir Piersaint, and Christine Spaulding. The present project was originally defended as a dissertation and was later presented as part of a panel chaired by the first author at the 2016 International Meeting for Autism Research (IMFAR) in Baltimore, MD. The current project was completed in honor of the first author’s former graduate school advisor, Dr. Edward “Ted” Carr.
