Abstract:
The present study aims to explore self-injury within a sample of college undergraduates, specifically with regards to the connection between borderline personality disorder features (BPD) and potential subtypes of self-harmers. Specifically, the current study aims to identify subtypes of self-harmers in a sample of college undergraduates who report a lifetime history of engaging in self-injury. Based on existing literature, we expect that classes of self-harmers will emerge based on engagement in self-injury for intrapersonal versus interpersonal reasons. Furthermore, once subtypes of self-harmers are established, we will conduct correlational analyses to assess whether these classes are related to BPD symptoms. Although this question is largely exploratory, we expect that subtypes of self-harmers will be related to BPD symptoms overall. Finally, the present study aims to determine which BPD features are the best predictors of each established subtype. In light of previous work connecting BPD features and the presence/absence of self-injury, we expect that identity disturbance, emptiness, and affective instability will be the best predictors of self-harm, especially in an intrapersonal context, whereas efforts to avoid abandonment will likely predict self-harm in an interpersonal context.
