The Function of Self-Harm: Understanding Nonsuicidal Self-Injury Among System-Involved Youth

Brooke Hailey, PhD, LMFT

Training Description

This training examines the function of nonsuicidal self-injury (NSSI) among system-involved youth (SIY), moving beyond behavior management toward understanding what self-harm communicates and regulates. Participants will review core principles of NSSI theory, including emotion regulation, communication, self-punishment, and sensation-seeking functions, and how these differ from suicidal intent. Through structured case analysis and applied exercises, participants will develop skills to conduct trauma-informed risk assessment and respond in ways that reduce reinforcement while increasing connection and safety. The training is designed to improve participant competency in assessing risk, reducing contagion, and supporting emotional regulation in SIY who self-harm.

Learning Objectives

• Identify and differentiate at least four functions of nonsuicidal self-injury (e.g., emotion regulation, communication, self-punishment, sensation seeking) in SIY behavior.

• Distinguish nonsuicidal self-injury from suicidal behavior using at least three risk assessment indicators for SIY.
