摘要

Child irritability (CI) is a transdiagnostic symptom of multiple psychopathologies, is prospectively associated with negative psychosocial outcomes, and may influence or be influenced by family functioning. The current study assessed bidirectional relations between CI and family conflict (FC) among youth (N = 10,608, Mage = 9.48 years, 47% female, 49.5% White) and one parent (85.3% mothers) across five years in the Adolescent Brain Cognitive Development study. In latent growth curve models with structured residuals, both boys and girls demonstrated curvilinear changes in FC and CI over time, with increasing and subsequently decreasing CI and the reverse trajectory for FC. Significant bidirectional, prospective associations between FC and CI, however, were only present for girls. Early CI was associated with FC one year later, while girls’ reports of FC were associated with later CI across all timepoints. Findings highlight biological sex as a critical factor influencing associations between family functioning and children’s symptoms.
