ABSTRACT Early adversity is a well‐established risk factor for psychopathology in youth. Contemporary taxonomies of adversity seek to distill the diverse stressors children face into meaningful categories of experience to enable more precise prediction of risk; however, few studies have tested these models using data‐driven approaches in well‐characterized, longitudinal samples. Here, we examined the latent structure of early stress across diverse domains of exposure, tested differential associations with psychopathology in adolescence, and investigated frontolimbic functional connectivity as a potential mediator. In a sample of 168 youth ( M age = 11.36), factor analyses identified two latent stress factors at baseline—“Parenting” and “Deprivation & Unpredictability”—and a single “Psychopathology” factor extracted from measures of mental health obtained 2 years later. While adverse parenting predicted greater psychopathology, exposure to threat emerged as the strongest predictor of adolescent mental health problems. High‐dimensional regularized mediation analyses revealed that frontolimbic functional connectivity mediated the association between Threat and Psychopathology in girls but not in boys. These findings suggest that widely used dimensional models overlook key aspects of adversity, including sex‐linked asymmetries across neurodevelopment and the distinct role of parenting‐related stress. Refining adversity taxonomies across diverse samples and stress domains is crucial to advancing targeted interventions for youth mental health.
