Recent research on the etiology of psychiatric disorders suggests that child maltreatment affects a circumscribed set of centralized risk mechanisms, known as transdiagnostic mechanisms, responsible for the increased incidences of multiple psychiatric disorders in this population. This project is testing the feasibility and initial efficacy of delivering individual components to alter unique transdiagnostic mechanisms following an act of child maltreatment to optimize intervention effects and reduce the incidences of multiple psychiatric disorders.
