RESUMEN
BACKGROUND: Juvenile justice-involved youth have high rates of trauma exposure, physical and sexual abuse and PTSD. Several factors have been found to be related to PTSD symptoms in youth including number and chronicity of traumatic events. OBJECTIVE: To simultaneously examine the relationships between allostatic load (defined here as number of traumatic experiences), poly-victimization (exposure to two or more forms of victimization based on 5 of the 6 categories in Ford et al.'s 2010 study), physical/sexual abuse and PTSD in justice-involved youth. PARTICIPANTS AND SETTING: The sample consisted of 1984 youth in juvenile detention in a Northeastern city. The sample was 73.4% male and the majority of youth were either African American or Hispanic. METHODS: Clinicians collected demographic and psychosocial information, and measured symptoms of PTSD, depression, and problematic substance use. RESULTS: Results showed that youth with more traumas, those who experienced poly-victimization and those who experienced physical/sexual assault/abuse were not only more likely to have PTSD, but also more likely to have depression, thoughts of suicide/self-harm, and problematic substance use (as indicated by the presence of 2 or more of 6 possible indicators). Poly-victimization was a stronger correlate of PTSD than number of traumas or physical/sexual assault/abuse. However, among youth with PTSD, number of traumas was associated with co-occurring problems while poly-victimization and physical/sexual assault/abuse were not. CONCLUSIONS: Findings can be used to help direct resources to juvenile justice-involved youth who are most in need of treatment.
