Trauma-Informed Peer Aggression and Dating Violence Prevention for Preteens Receiving Intensive Mental Health Services

The goal of this clinical trial is to learn if this intervention (Social Skills, Problem Solving, emotion Regulation, and psycho-Education on Trauma: A Trauma-Informed Peer Aggression and Teen Dating Violence Prevention Program; SPARE) can treat peer aggression and prevent teen dating violence in preteens receiving intensive mental health services. The main questions it aims to answer are: * Does receiving SPARE reduce proactive and reactive aggression at post-intervention and 3- and 9-month follow-ups? * Does receiving SPARE reduce positive attitude about TDV, prevent TDV behaviors, and improve mental health outcomes at post-intervention and 3- and 9-month follow-ups? Researchers will compare youth receiving SPARE to youth receiving treatment as usual to see if SPARE results in improved proactive and reactive aggression, TDV attitudes and behaviors, and mental health outcomes. Participants will: * Receive SPARE via group therapy incorporated into their daily programing at an intensive mental health program * Complete study questionnaires at program intake and discharge as well as at 3-month and 9-month follow-up assessments
