Interpersonal-psychological Theory Of Suicidal Behavior Research Articles

Main predictions of the interpersonal–psychological theory of suicidal behavior: Empirical tests in two samples of young adults.

The interpersonal-psychological theory of suicidal behavior (T. E. Joiner, 2005) makes 2 overarching predictions: (a) that perceptions of burdening others and of social alienation combine to instill the desire for death and (b) that individuals will not act on the desire for death unless they have developed the capability to do so. This capability develops through exposure and thus habituation to painful and/or fearsome experiences and is posited by the theory to be necessary for overcoming powerful self-preservation pressures. Two studies tested these predictions. In Study 1, the interaction of (low) family social support (cf. social alienation or low belonging) and feeling that one does not matter (cf. perceived burdensomeness) predicted current suicidal ideation, beyond depression indices. In Study 2, the 3-way interaction among a measure of low belonging, a measure of perceived burdensomeness, and lifetime number of suicide attempts (viewed as a strong predictor of the level of acquired capability for suicide) predicted current suicide attempt (vs. ideation) among a clinical sample of suicidal young adults, again beyond depression indices and other key covariates. Implications for the understanding, treatment, and prevention of suicidal behavior are discussed.

Understanding Suicidal Behavior in the Military: An Evaluation of Joiner's Interpersonal-Psychological Theory of Suicidal Behavior in Two Case Studies of Active Duty Post-Deployers

Suicide in the military is a growing concern. We reviewed empirical studies and used two case studies to illustrate the potential explanatory role of Joiner's (2005) interpersonal-psychological theory of suicidal behavior. The theory posits that three variables—perceived burdensomeness, thwarted belongingness, and acquired capability for suicide—determine the risk of an individual engaging in a lethal suicide attempt. In our case studies, we illustrate how these variables might be affected in an active duty population post-deployment. Although methodological limitations preclude conclusive determinations, the case studies provide a framework within which to understand the phenomenon of suicide in the military. Future work that examines these findings empirically will be invaluable to both researchers and mental health counselors.

Suicidal Ideation in College Students Varies Across Semesters: The Mediating Role of Belongingness

The interpersonal-psychological theory of suicidal behavior (Joiner, 2005) proposes that the need to belong is fundamental; when met it can prevent suicide and when thwarted it can substantially increase the risk for suicide. We investigate one source of group-wide variation in belongingness among college students--changes in the social composition of college campuses across academic semesters--as an explanation for variation in suicidal ideation across the academic year. Our results indicate that in a sample of college students at a large southern state university (n = 309), suicidal ideation varied across academic semesters, with highest levels in summer compared to both spring and fall. Differences in suicidal ideation between summer and spring were, in large part, accounted for by belongingness. Theoretical, as well as practical, implications are discussed regarding mechanisms for seasonal variation in suicidal ideation.

Suicidal desire and the capability for suicide: Tests of the interpersonal-psychological theory of suicidal behavior among adults.

The interpersonal-psychological theory of suicidal behavior (T. E. Joiner, 2005) proposes that an individual will not die by suicide unless he or she has both the desire to die by suicide and the ability to do so. Three studies test the theory's hypotheses. In Study 1, the interaction of thwarted belongingness and perceived burdensomeness predicted current suicidal ideation. In Study 2, greater levels of acquired capability were found among individuals with greater numbers of past attempts. Results also indicated that painful and provocative experiences significantly predicted acquired capability scores. In Study 3, the interaction of acquired capability and perceived burdensomeness predicted clinician-rated risk for suicidal behavior. Implications for the etiology, assessment, and treatment of suicidal behavior are discussed.

Perceived Burdensomeness as an Indicator of Suicidal Symptoms

The Interpersonal-Psychological Theory of Suicidal Behavior proposes precursors to serious suicidality, including the perception that one is a burden on loved ones. The purpose of the present study was to evaluate the association of perceived burdensomeness and key suicide-related variables in 343 adult outpatients of the Florida State University Psychology Clinic (187 female; 156 male). Participants completed the Beck Scale for Suicide Ideation and the Beck Depression Inventory, as well as items on perceived burdensomeness and hopelessness. Perceived burdensomeness remained a significant predictor of suicidality indicators (i.e., attempt status and BSSI scores) above and beyond the contribution one of the most robust predictors of suicidality, hopelessness. Results suggest that both burdensomeness and hopelessness display predictive power with regards to suicidal behavior and that perceived burdensomeness displayed the signature of a resilient suicide risk factor. Thus, targeting perceived burdensomeness in the assessment of suicidal behavior may aid in treatment and prevention efforts.
