Despite numerous studies asserting the prevalence of marital conflict among families of children with attention-deficit hyperactivity disorder (ADHD), evidence is surprisingly less convincing regarding whether parents of youth with ADHD are more at-risk for divorce than parents of children without ADHD. Using survival analyses, this study compared the rate of marital dissolution between parents of adolescents and young adults with and without ADHD. Results indicated that parents of youth diagnosed with ADHD in childhood (n=282) were more likely to divorce and had a shorter latency to divorce than parents of children without ADHD (n=206). Among a subset of those families of youth with ADHD, prospective analyses indicated that maternal and paternal education level, paternal antisocial behavior, and child age, race/ethnicity, and oppositional-defiant/conduct problems each uniquely predicted the timing of divorce between parents of youth with ADHD. These data underscore how parent and child variables likely interact to exacerbate marital discord and, ultimately, dissolution among families of children diagnosed with ADHD in childhood.
