Nonsuicidal self-injury in sexual minorities in Korea: the mediating role of intrapersonal functions and depression

Abstract

A growing body of literature indicates that individuals belonging to sexual minority groups are at an increased risk of severe nonsuicidal self-injury (NSSI) behaviors. This study aimed to examine the potential factors mediating sexual minority status and more severe NSSI behaviors. A total of 296 self-identified sexual minorities and 206 heterosexuals who reported engaging in at least five-lifetime NSSI episodes were recruited online. The participants completed an online survey that included demographics, measures of depressive symptoms, and the frequency and functions of NSSI behaviors. Serial mediation analyses indicated that the association between sexual minority status and more frequent NSSI behaviors was mediated by depressive symptoms and intrapersonal functions of NSSI. Further analyses revealed that NSSI functions may vary by minority status, with individuals reporting a sexual minority status showing more frequent endorsements of intrapersonal functions. This study’s findings contribute to the literature by elucidating the complex role of clinical factors that mediate the relationship between sexual minority status and increased risk of engaging in more frequent NSSI behaviors. Our findings underscore the importance of developing a comprehensive perspective on NSSI behaviors, including the characteristics of NSSI functions and current clinical symptoms, as well as disadvantaged backgrounds, such as minority status.
