Research Summary

The underlying goal of my research is to ensure that effective behavioral treatments are available to all individuals, and especially to those with high-risk problems like suicidal ideation or substance abuse. To this end, my research spans three areas: suicide and its correlates, emotion dysregulation as a potential mechanism for suicide and other high-risk behaviors such as substance use, and the development, adaptation, and implementation of skills-based behavioral treatments. Suicide was the tenth leading cause of death in the United States in 2019, and is particularly common among individuals who have served in the Armed Forces. Suicide is preventable and multifactorial, not linked to just one mental health concern. My work includes examining emotion dysregulation as a potential transdiagnostic mechanism for suicidal ideation and behavior, and developing and implementing related behavioral treatments such as Dialectical Behavior Therapy Skills Groups (DBT-SG). My most significant contribution to date is the systematic study of a skills group adaptation of DBT, the most well supported treatment for high-risk suicidal individuals with borderline personality disorder. I developed this DBT-SG adaptation from a clinical project into a pilot (Decker et al., 2019) and secured funding for a national hybrid effectiveness- implementation trial at four VA medical centers with co-PI Steve Martino, PhD. This project will help answer longstanding questions about whether DBT Skills Groups can help Veterans reduce suicide attempt and will provide information about barriers and facilitators to this treatment in real-world care settings.
