Verbal Ability, Behavior Problems, and Mother–Child Relationship Quality in Autism Spectrum Disorder

This study examined differences in mother–child relationship quality and parent-rated child behavior problems based on child verbal status (i.e., minimally verbal versus verbal) in mothers and their adolescent and adult children with autism spectrum disorder (n = 219 dyads; child M_age = 25.38 years, SD = 10.22). Relationship quality was assessed via parent-reported maternal burden and mother–child closeness, and coded speech samples ascertaining maternal critical and positive remarks regarding the child. Groups did not differ in relationship quality. The verbal group was more likely to display disruptive and socially inappropriate behaviors, but otherwise the groups did not differ in behavior problems. Verbal status moderated the relationship between behavior problems and negative (maternal burden, critical remarks) but not positive (mother–child closeness, positive remarks) aspects of relationship quality.
