The dualistic model of passion proposes two passion types, harmonious and obsessive, representing adaptive and maladaptive passion, respectively. Studies suggest interpersonal experiences explain harmonious passion benefits and obsessive passion negative consequences. However, research has not examined passion among individuals with clinically elevated suicide risk, nor the associations between passion types and suicide-related outcomes. The present study presents a conceptual model linking the dualistic model of passion and the interpersonal theory of suicide constructs [specifically, thwarted belongingness (TB) and perceived burdensomeness (PB)]. U.S. adults with clinically elevated suicide risk (N = 484) completed online, cross-sectional assessments of harmonious and obsessive passion, TB, PB, and future dispositions (i.e., positive focus, negative focus, and suicide orientation). A mediation model indicated the effects of harmonious and obsessive passion on positive and negative focus and suicide orientation were largely explained by TB and PB. The present findings suggest engaging in a passion activity may be meaningfully related to suicide-related interpersonal perceptions (i.e., TB and PB).
