Abstract

BACKGROUND: High rates of suicidal ideation in those with social anxiety disorder (SAD) have been attributed to feelings of thwarted belongingness and perceived burdensomeness, but most work has been in non-clinical samples. We assessed the contributions of thwarted belongingness and perceived burdensomeness to suicidal ideation severity, over clinical covariates, in individuals diagnosed with SAD.
METHODS: Participants were 58 adult outpatients (mean age 25.62 years, 69% female) with SAD. Hierarchical linear regression assessed contributions of thwarted belongingness and perceived burdensomeness to suicidal ideation, before and after covarying other potential explanatory variables (depression, agitation, brooding rumination).
RESULTS: Perceived burdensomeness was significantly positively related to suicidal ideation severity (p < .001) above thwarted belongingness, which was not incremental (p = .791). The same pattern was found after inclusion of additional covariates (perceived burdensomeness p = .006; thwarted belongingness p = .757). Greater agitation also uniquely accounted for more severe suicidal ideation (p = .001).
LIMITATIONS: This study was cross-sectional, did not assess all potential confounding variables, and utilized a treatment-seeking sample.
CONCLUSIONS: Results suggest perceived burdensomeness is independently related to suicidal ideation severity in SAD, over thwarted belongingness and other clinical features. Future work should seek to replicate these findings and evaluate causal, longitudinal relationships among perceived burdensomeness, agitation, and severity of suicidal ideation in those with SAD in order to determine whether these may be clinically-relevant mechanisms.
