(PS2-C65) Exploring Non-suicidal Self-injury and Suicidality Through the Application of the Interpersonal Theory of Suicide in Homeless Individuals

Individuals without housing have a 10x higher risk of suicide compared with the population at large (National Healthcare for the Homeless Council, 2018). Despite this, little research has investigated suicidality or the application of theories of suicide within this population. Individuals without housing are particularly vulnerable to social isolation and stress across many areas of life, both of which have been found to be associated with increased rates of suicide attempts and ideation as well as having predictive ability for future suicide attempts (Coohey et al., 2015). This study aims to investigate the interpersonal theory of suicide (Joiner & Silve, 2012) among individuals without housingn. By investigating the constructs of perceived burdensomeness and thwarted belongingness in this population, we will better understand suicidality within a marginalized and underserved population that is at high risk. Further, this research will inform treatments for suicide within this community. Researchers are partnering with a local homeless shelter to recruit participants for this study.  Data collection is ongoing and  will be completed by May 2022.
