Adolescent self-harm may trace back to subtle maternal social-cognitive patterns that persist across generations. This connection challenges traditional approaches to treating self-injury behaviors that focus primarily on the adolescent rather than examining family-wide neurocognitive dynamics.
Researchers analyzed 100 mother-daughter pairs where adolescents either engaged in non-suicidal self-injury, had attempted suicide with self-injury, or served as healthy controls. Mothers of teens practicing self-harm demonstrated significantly impaired emotion recognition abilities on the Reading the Mind in the Eyes Test, scoring lower than mothers of control adolescents. These deficits persisted even after accounting for socioeconomic factors and maternal smoking. Additionally, these mothers showed specific weaknesses in autism spectrum social skills subscales, though overall autism quotient scores remained normal.
This research expands understanding of intergenerational transmission of psychological vulnerability beyond genetic predisposition to include specific cognitive processing differences. The findings suggest that maternal difficulties reading emotional cues may contribute to family environments where adolescents develop maladaptive coping mechanisms. Particularly notable was the discovery that suicide-attempting teens reported using self-harm specifically for interpersonal influence, suggesting these mother-child pairs may have developed complex communication patterns around emotional distress. While the study establishes correlation rather than causation, it opens new therapeutic avenues focusing on enhancing maternal mentalization skills alongside direct adolescent intervention. The research remains limited by its case-control design and requires longitudinal validation to confirm developmental pathways.
