This study will compare treatment outcomes of 90 adolescent girls who are (a) at high risk for delinquency and/or are juvenile justice involved, and (b) who are experiencing symptoms of PTSD: 45 of the girls will receive Trauma Affect Regulation: Guide for Education and Therapy (TARGET, Frisman, Ford, Lin, Mallon, & Chang, in press), and their outcomes will be compared to 45 girls who receive Enhanced Treatment as Usual (ETAU). As part of their involvement, participants will make phone calls to provide data via an interactive voice response system (IVR), meet 3 times for a research interview, and be invited to participate in a cognitive assessment substudy at the Olin Neuropsychiatric Research Center at Hartford Hospital.
