Interrupting the Cycle: Association of Parental Stress and Child/Youth Psychotropic Medication Nonadherence

Efficacy of psychotropic medication depends in large part on successful adherence to prescribed regimens. This study investigated child/youth nonadherence in relation to family dynamics and informal support. The participants were 10,225 children and youth prescribed psychotropic medication and receiving services from 50 Ontario mental health agencies, assessed with the interRAI™ Child and Youth Mental Health (ChYMH) and ChYMH-Developmental Disability (ChYMH-DD) tools. Findings suggest a cycle of parental stress and child/youth medication nonadherence possibly leading to or even perpetuated by worsening psychiatric symptoms. Informal supports do not appear to moderate this cycle. While the present data cannot speak to causes of medication nonadherence in children/youth or where the cycle begins, the results are consistent with the extant literature calling for attention to parental wellbeing to support children/youth for optimal therapeutic benefits. Understanding home dynamics related to nonadherence can assist care planning that engages the family to achieve best possible child/youth outcomes.
