While it may be true that a subset of batterers have Narcissistic/Borderline personality features, there are others who don't have that personality constellation or degree of malevolence. We (a trauma center with programs for child sex abuse survivors, adults with child sex abuse histories, children and adults with a history of DV, youth with problematic sexual behaviors) are interested in helping a Batterers program based in our local probation department become trauma informed, and are thinking about ways to screen for trauma. Considering using the ACE screen or the Life Events Checklist, and whether a PO or a clinician should administer it (balancing the optimal with the pragmatic).
