Nonsuicidal self-injury (NSSI) is a common clinical concern. We surveyed a national sample of 94 licensed clinicians to better understand their work with clients who self-injure. Our data revealed that over the past year, 95.7% (n = 90) of the sample reported working with at least one client who self-injured. Thirty-six clinicians (38%) reported that most or all of their clients who self-injured were adolescents, 61 (64.9%) reported that most or all clients who self-injured were female, and 43 (45.7%) reported that most or all clients who self-injured engaged in cutting as the primary NSSI method. About 35% (n = 33) of the clinicians in our sample indicated they have never asked clients who self-injured about their online activity related to NSSI. The majority of our participants (n = 78; 83%) supported the notion that NSSI could be an addictive behavior for some clients and less than half (n = 42; 44.7%) received NSSI training in their graduate coursework.
