Functions, Consequences, and Frequency of Non-suicidal Self-Injury.

We examined the correspondence between reported reasons and consequences for a specific act of non-suicidal self-injury (NSSI), and their relationship with lifetime NSSI frequency. College students with a history of NSSI (n = 52) indicated reasons for and consequences from their most recent NSSI episode. A match was coded when a reason and its corresponding consequence(s) were both endorsed by the participant. Reasons and consequences were significantly correlated, but their correspondence was not related to lifetime NSSI frequency. Automatic negative reasons explained lifetime NSSI frequency, but consequences and match between reasons and consequences did not. Reported reasons for NSSI may be more important in understanding maintenance of NSSI than either consequences or match.
