Prevalence of methylphenidate use among Canadian children following parental divorce

It is time for a more integrated bio-psycho-social approach to ADHD

The role of psychosocial factors in perpetuating and predisposing towards the development of attention deficit hyperactivity disorder (ADHD) symptoms has been neglected within the field of child mental health. Clinicians, when told that a child had a diagnosis of ADHD, have been found to underestimate the presence of psychosocial factors, and are less likely to ask about the possibility of neglect or abuse. This article details the considerable research showing links between ADHD symptoms and parental mental illness, child maltreatment, post-traumatic stress disorder (PTSD), attachment disorders and other environmental factors. Recent neuro-biological findings showing the impact on brain development of early abuse and attachment concerns are cited. The implications of these findings both for clinicians, and at policy level, are discussed, and the reasons underlying the need for a more integrated Bio-Psycho-Social approach to ADHD are outlined.

Rate and predictors of divorce among parents of youths with ADHD

Numerous studies have asserted the prevalence of marital conflict among families of children with attention-deficit/hyperactivity disorder (ADHD), but evidence is surprisingly less convincing regarding whether parents of youths with ADHD are more at risk for divorce than are parents of children without ADHD. Using survival analyses, the authors compared the rate of marital dissolution between parents of adolescents and young adults with and without ADHD. Results indicated that parents of youths diagnosed with ADHD in childhood (n = 282) were more likely to divorce and had a shorter latency to divorce compared with parents of children without ADHD (n = 206). Among a subset of those families of youths 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 youths 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.
