Association between perceived social support and suicide ideation distress among psychiatric inpatients: The role of thwarted interpersonal needs

IntroductionThe interpersonal theory of suicide posits that thwarted belongingness (TB) and perceived burdensomeness (PB) are proximal risk factors for suicide ideation; however, there are mixed results regarding this hypothesis among psychiatric inpatients. ObjectiveThe current study examined the mediating role of TB and PB in the relationship between perceived social support (i.e., support from family, friends, a significant other, and total) and suicide ideation distress among psychiatric inpatients. MethodsParticipants (short-term psychiatric inpatients; N = 139) were administered self-report assessments cross-sectionally. ResultsNonparametric mediation results indicated that the total (additive) indirect effects of TB and PB, in parallel, were significant in all models, yet there were only significant specific (unique) indirect effects of PB. ConclusionTB and PB, in combination, may be proximal risk factors for suicide ideation distress among psychiatric inpatients with lower perceived social support from family, friends, a significant other, and in total. These findings are congruent with the interpersonal theory of suicide's propositions that the combination of TB and PB increases the risk for suicide ideation. Clinicians may consider using interventions that target increasing perceived social support and decreasing TB and PB (i.e., cognitive behavioral therapy and social skills training) for this population.

Automated summary

This study examined the mediating role of thwarted belongingness (TB) and perceived burdensomeness (PB) in the relationship between perceived social support and suicide ideation distress among psychiatric inpatients. The results showed that the combination of TB and PB may be proximal risk factors for suicide ideation distress among psychiatric inpatients with lower perceived social support.
