Add one more concern for families with children on the autism spectrum: divorce.
Any parents of young children are usually stressed and strapped for time, leaving them with little energy to devote to their spouses. As such, divorce rates are highest when a couple has young children. However, once the children enter their teens and become more self-sufficient, the divorce rate tapers off.
However, a child with an autism spectrum disorder requires extra attention, not only throughout their childhood, but also into their teens and even adult lives. These children also tend to have communication difficulties and engage in repetitive behaviors, which can add even more stress for the parents. Their parents are never given that "break" that other parents experience as their children grow up. This is probably why parents of an autistic child are sometimes told that the divorce rate for couples in their situation is as high as 80%.
To see if this extreme statistic held any truth, researchers from the University of Wisconsin-Madison, Georgia State University and Boston University examined 391 families participating in the Adolescents and Adults With Autism study. These families were compared to other families with children whose development was considered normal. The study matched the families based on the age, sex and birth order of the child with autism and the age, education and ethnicity of the mother.
