Objective: We examined whether meaningful subgroups of self-injurious behaviors (SIBs) would emerge within a pool of first-year college students already deemed at elevated risk. Participants: First-year undergraduates (N = 1,068) recruited in 2015-2018 Fall terms. Methods: Past-year nonsuicidal self-injury (NSSI) frequency, past-year number of NSSI methods used, lifetime suicide attempt (SA) history, and recency of SA were included in a latent profile analysis. Results: Four subgroups emerged: "low SIB" (n = 558, 52%), "high NSSI only" (n = 182, 17%), "high SIB" (n = 141, 13%), and "high SA only" (n = 187, 18%). Students in the "high SIB" group reported higher levels of suicidal ideation at baseline and follow-up in comparison to all groups. Those in the "high NSSI only" or "high SIB" groups had relatively higher levels of NSSI at baseline and follow-up. Conclusions: Findings highlight the amount of heterogeneity "within" a high-risk group, along with the importance of considering distal and proximal SIBs in university screening efforts.
