BACKGROUND We aimed to identify profiles of ambivalence among individuals with a history of non-suicidal self-injury (NSSI) and tested whether profiles differed across various theoretically informed constructs: NSSI-related characteristics, cognitive (outcome expectancies, self-efficacy to resist NSSI), emotional (psychological distress, difficulties in emotion regulation), personality, and incentives to engage/not engage in NSSI. METHODS Individuals with a lifetime history of NSSI (n = 224) reported the extent to which they wanted to and did not want to engage in NSSI and completed well-validated measures of the constructs of interest. RESULTS Latent profile analysis indicated four ambivalence profiles (avoid: n = 39; moderately ambivalent: n = 85; highly ambivalent: n = 30; approach: n = 70). The profiles differed across a number of NSSI-related characteristics, cognitive, emotional, and incentive-related variables. Differences between the ambivalence profiles and the avoid/approach profiles varied across constructs. For example, the ambivalence and approach profiles were similar for NSSI-related outcome expectancies, but the ambivalence and avoidance profiles were similar for self-efficacy to resist NSSI. CONCLUSION Findings highlight variation between the desire to engage or not engage in NSSI that are consistent with the notion of ambivalence. Understanding these differences may allow for a more person-centered approach in treatment for NSSI.
