Potentially traumatic events in foster youth, and association with DSM-5 trauma- and stressor related symptoms.

BACKGROUND: In DSM 5, three disorders are related to trauma and/or maltreatment: Post-traumatic Stress Disorder (PTSD), Reactive Attachment Disorder (RAD) and Disinhibited Social Engagement Disorder (DSED) but how these disorders relate to each other and to traumatic events is unknown.

OBJECTIVE: We examined 1. Prevalence of Potentially Traumatic Events (PTEs) and poly-victimization for youths in foster care. 2. Associations between single/multiple PTEs and PTSD, DSED, and the two symptom-clusters that constitute RAD: Failure to seek/accept comfort (RAD A), and Low social-emotional responsiveness/ emotion dysregulation (RAD B).

PARTICIPANTS, SETTING AND METHODS: Foster youth 11-17 years (N = 303) in Norway completed The Child and Adolescent Trauma Screen. Foster parents completed the RAD and DSED Assessment interview.

RESULTS: Foster youth reported experiencing, on average, 3.44 PTEs each (range 0-15, SD 3.33), and 52.9 % reported PTSD symptoms at or above clinical cut off. The PTE sum score was associated with the latent factors PTSD (r = .66, p < 0.001), RAD cluster B symptoms (Low social-emotional responsiveness / emotion dysregulation, r = .28, p < 0.001) and DSED (r = .11, p = 0.046), but not with RAD cluster A symptoms (Failure to seek/accept comfort).

CONCLUSIONS: These findings raise new questions about the nature, mechanisms and timing of development of RAD and DSED. Maltreatment assessment needs to encompass a wide range of PTEs, and consider poly-victimization.
