Reduced growth mindset as a mechanism linking childhood trauma with academic performance and internalizing psychopathology

Despite the high prevalence of childhood adversity and well-documented associations with poor academic achievement and psychopathology, effective, scalable interventions remain largely unavailable. Existing interventions targeting growth mindset—the belief that personal characteristics are malleable—have been shown to improve academic achievement and symptoms of psychopathology in youth. The present study examines growth mindset as a potential modifiable mechanism underlying the associations of two dimensions of childhood adversity—threat and deprivation—with academic achievement and internalizing psychopathology. Participants were 408 youth aged 10–18 years drawn from one timepoint of two longitudinal studies of community-based samples recruited to have diverse experiences of childhood adversity. Experiences of threat and deprivation were assessed using a multi-informant, multi-method approach. Youth reported on growth mindset of intelligence and symptoms of anxiety and depression. Parents provided information about youths' academic performance. Both threat and deprivation were independently associated with lower growth mindset, but when accounting for co-occurring adversities, only the association between threat and lower growth mindset remained significant. Lower growth mindset was associated with worse academic performance and greater symptoms of both anxiety and depression. Finally, there was a significant indirect effect of experiences of threat on both lower academic performance and greater symptoms of anxiety through lower growth mindset. Findings suggest that growth mindset could be a promising target for efforts aimed at mitigating the impact of childhood adversity on academic achievement and psychopathology given the efficacy of existing brief, scalable growth mindset interventions. •Adversity-related differences in growth mindset were examined in adolescents.•Both threat and deprivation were negatively associated with growth mindset.•Lower growth mindset mediated association between threat and academic performance.•Lower growth mindset mediated association between threat and anxiety symptoms.•Supporting growth mindset could mitigate impact of trauma on adolescent outcomes.
