Abstract

The Interpersonal Psychological Theory of Suicide (i.e., IPTS) proposes that suicidal desire occurs when an individual simultaneously experiences thwarted belongingness (TB) and perceived burdensomeness (PB) (i.e., interpersonal needs). However, interpersonal needs have been inconsistent in predicting suicide ideation in Koreans. Therefore, we examined depressogenic personality dimensions-sociotropy and autonomy-as individual differences that may alter the effects of TB and PB on suicide ideation. We hypothesized that sociotropy will amplify the influence of TB on suicide ideation and that autonomy will regulate the degree to which PB leads to suicide ideation. This study was conducted with undergraduate students from a university located in Seoul, Korea. 313 students of whom 113 were males (36.1%) and 200 were females (63.9%) were included in the final analyses. Among the 313 participants, 42 (20.3%) endorsed suicide ideation. Significant correlations were identified between sociotropy and depression, and autonomy and depression. PB and sociotropy were valid predictors of suicide ideation even after controlling for depression. In addition, significant interactions were found between sociotropy and TB, and autonomy and PB.
