Trauma-Focused Mitigation Testimony in Capital Sentencing Hearings.

When capital trials of convicted defendants reach the sentencing phase, forensic mental health experts often testify as part of mitigation evidence. Three aspects of such testimony hold particular promise. First, developmental traumas in the lives of the defendants are especially well conceptualized in terms of complex posttraumatic stress disorder, as described in the ICD-11. Second, Cunningham's framework, which critically examines the impact of harmful and protective factors over the course of a defendant's development, allows for an examination of moral culpability apart from legal culpability. Third, specific training on trauma and its effects on personality and psychopathology allows forensic mental health professionals to more skillfully complete trauma mitigation evaluations.
