Collateral Consequences for Third-Party Interviewees in Forensic Contexts.

Collateral interviews can be an integral source of third-party information used in a range of forensic mental health assessments. Although family members and spouses often have the most knowledge about the evaluee, research suggests that they may also experience distress related to the legal proceedings. This article discusses the nature and purpose of collateral interviewing with close collateral contacts, comparing collateral interviews with direct interviews with evaluees. The secondary consequences of having a justice-involved family member are considered, including the possibility of vicarious trauma. Finally, the responsibilities of evaluators are considered, especially in the context of trauma-informed principles applied to collateral interviewing. Recommendations regarding consent, the use of empathy, and feedback to collateral are provided.
