Abstrakt: Objective: Despite the robust relation between nonsuicidal self-injury (NSSI) and suicidal behaviors, there is considerable heterogeneity in NSSI characteristics that may have implications for the strength of the NSSI-suicide attempt relation. Past research highlights the relevance of both more severe NSSI methods and NSSI in the form of cutting in particular to suicide attempts. To further explore the relations of specific NSSI methods to suicide attempts, this study examined relations between different NSSI methods (i.e., those involving cutting, burning, blunt force, or resulting in minor tissue damage) and both overall suicide attempts and two indicators of suicide attempt severity (attempts requiring medical attention and nonambivalent attempts) in 203 substance-dependent patients in residential treatment.
Method: Participants were administered questionnaires and semistructured interviews assessing the variables of interest.
Results: Cutting was the only NSSI method to demonstrate significant relations with overall suicide attempts, nonambivalent suicide attempts, and suicide attempts requiring medical attention. Results remained when considering relevant covariates.
Conclusion: Results highlight an important link between NSSI methods involving cutting and suicide attempts among patients with substance use disorders. Findings also highlight the importance of more fine-grained characterizations of NSSI subgroups.
