Adolescent Mental Health Following Exposure to Positive and Harsh Parenting in Childhood.

Abstract

The purpose of the present study was to assess longitudinal associations between positive and harsh parenting in childhood and adolescent mental and behavioral difficulties. Data were drawn from Canada's population-based National Longitudinal Survey of Children and Youth (data collected from 1994 to 2009, analyzed 2018). The sample included 9,882 adolescents aged 12/13 years old. Parents self-reported positive and harsh parenting when children were 6/7, 8/9, and 10/11 years old. Symptoms of depression/anxiety, hyperactivity, physical aggression, social aggression, and suicidal ideation were self-reported by adolescents at age 12/13. Linear regression was used to examine the associations between parenting behaviors at each age and adolescent psychiatric symptoms, adjusted for children's baseline symptoms. Harsh parenting at 10/11 was associated with elevated symptoms of early-adolescent physical aggression, social aggression, and suicidal ideation for boys only, and for all children at earlier ages. Beginning at age 8/9, harsh discipline was associated with elevated symptoms of depression/anxiety for boys only. Overall, positive parenting at age 6/7 was protective against depression/anxiety, physical aggression, and social aggression. Significant sex differences emerged beginning at age 8/9, with positive parenting associated with higher symptoms of depression/anxiety for boys only. Positive parenting at age 10/11 was associated with increased depression/anxiety, physical aggression, social aggression, and suicidal ideation among boys, but decreased symptoms of physical aggression, social aggression, and suicidal ideation among girls. Results suggest that the impact of positive and harsh parenting may depend on age and sex, with harsh parenting being more detrimental to boys as they approach adolescence.
