| Popis: | Individuals who engage in non-suicidal self-injury (NSSI) are heterogeneous across several key features, including functions served by NSSI, frequency of NSSI behaviors, medical severity of injuries, pain experienced during self-injury, and the type and number of methods employed to self-injure. The present study utilized latent class analysis (LCA) to identify distinct subgroups of self-injurers based on a wide array of NSSI features. Participants were 359 undergraduate students with a history of NSSI. Indicator variables of the LCA were the lifetime presence of NSSI methods, number of methods used over one’s lifetime, lifetime and last year frequency rates, presence of NSSI scarring, rating of pain experienced when self-injuring, and functions of NSSI. The analysis yielded four subgroups of self-injurers: a “mild/experimental NSSI” group who endorsed low frequency rates of self-injury and low presence of NSSI functions, a “moderate NSSI” group that endorsed moderate frequency rates of self-injury and moderate presence of NSSI functions, a “moderate multiple functions NSSI” group that endorsed moderate frequency rates of self-injury and high presence of NSSI functions, and a “severe NSSI” group that endorsed high frequency rates of self-injury and high presence of NSSI functions. Following class assignment, groups were found to significantly differ on measures of self-esteem, social support and belongingness, internalizing symptoms, suicidal ideation and behaviors, and other related NSSI constructs. These subtype analyses provide direction for interventions that emphasize matching phenotypes of NSSI to specific interventions based on dimensions of clinical functioning. |
