What exactly constitutes nonsuicidal self-injury (NSSI)? Dr. Brooke Ammerman from the University of Notre Dame and Dr. Greg Lengel from Drake University discuss the complexities of defining NSSI. They also describe the difference between deliberate self-harm and NSSI and share their research about what many clinicians, researchers, and people with lived experience tell them about what they think constitutes NSSI and how we should define it.Learn more about Dr. Ammerman and her work in the Affect, Suicide, Self-Injury, and Social Triggers (ASSIST) Lab at https://assistlab.nd.edu/.
