The Interpersonal–Psychological Theory of Suicide in College Student Suicide Screening

Suicide screening on campus is limited by effectiveness of existing questionnaires. This study tests whether Interpersonal–Psychological Theory of Suicide (IPTS) constructs may be more effective in screening than traditional risk factors measures like the Interactive Screening Protocol (ISP). Participants were 188 traditional‐age students from three different campuses recruited through a subject pool and peer recruiters. IPTS risk variables as a set explained all likelihood of higher risk responses to suicidality questions that was otherwise explained by risk factors, plus additional likelihood besides. Current IPTS measures are no screening “magic bullet,” but further inquiry into use of these constructs is warranted.     

Examining the Interpersonal–Psychological Theory of Suicide in an Inpatient Veteran Sample

Suicide among veterans is a pressing public health concern. The interpersonal–psychological theory of suicide proposes that perceived burdensomeness and thwarted belongingness lead to suicidal desire, whereas the acquired capability for suicide leads to suicide attempt in the presence of suicidal desire (Joiner, 2005). Two hypotheses derived from the interpersonal–psychological theory of suicide were tested in 185 veterans (96 women) entering inpatient psychiatric treatment. Burdensomeness and its interaction with belongingness significantly predicted current suicidal ideation. The three‐way interaction between burdensomeness, belongingness, and acquired capability did not significantly predict number of past suicide attempts. Clinical implications and directions for future research are discussed.     

Understanding the Pathways from Depression to Suicidal Risk from the Perspective of the Interpersonal–Psychological Theory of Suicide

Suicide is a major public health concern, especially in adolescence. Identifying risk factors for suicide is important to effectively prevent such behavior. Depression is one of the most widely examined risk factors for suicidal risk. How depression and suicidal risk are related, however, is still not clear. This study tested a model with three key constructs of the interpersonal–psychological theory of suicidal behavior (IPTS)—perceived burdensomeness, thwarted belongingness, and nonsuicidal self‐injury (NSSI)—as mediators in the relationship between depression and suicidal risk among Chinese adolescents. Chinese high school students (N = 1,074; 54.2% male; M_age = 13.87 years, SD = 1.48) completed questionnaires assessing all study variables. Results suggested that perceived burdensomeness and NSSI partially mediated the relationship between depression and suicidal risk. Findings of this study emphasize the importance of the IPTS framework in understanding the possible mechanisms underlying the relationship between depression and suicidal risk, and suggest a possible avenue for suicide interventions.     

Interpersonal–Psychological Theory,Alexithymia, and Personality Predict Suicide Ideation among Maladjusted Soldiers in Taiwan

This case–control study enrolled 226 maladjusted soldiers and 229 controls to investigate the impact of the interpersonal–psychological theory of suicide, alexithymia, personality, and childhood trauma on suicide risk among Taiwanese soldiers. Assessments included the Toronto Alexithymia Scale, Eysenck Personality Inventory, Mini‐International Neuropsychiatric Interview, and Brief Symptom Rating Scale. In addition to thwarted belongingness and perceived burdensomeness, other risks included less extraversion with higher neuroticism, higher alexithymia, poor academic performance, domestic violence, and life‐threatening events. Our study demonstrates the interaction of the interpersonal–psychological theory and other suicide risk factors in Taiwanese soldiers.     

Comparisons of the Interpersonal–Psychological Theory of Suicide Constructs Among Individuals Without Suicidality,Ideators, Planners,and Attempters

The Interpersonal–Psychological Theory of Suicide (IPTS) proposes that combinations of thwarted belongingness, perceived burdensomeness, and acquired capability lead to suicide ideation, planning, and attempting. We compared individuals with and without suicidality on thwarted belongingness and perceived burdensomeness, and compared a combined group of planners and attempters to ideators on fearlessness about death (one component of acquired capability). Individuals with suicidality had higher thwarted belongingness and perceived burdensomeness than individuals without suicidality. Planners and attempters did not have higher fearlessness about death than ideators. These findings partially support IPTS hypotheses. Assessing thwarted belongingness and perceived burdensomeness may improve suicide risk determination.     

Moderating Factors in the Path from Physical Abuse to Attempted Suicide in Adolescents: Application of the Interpersonal‐Psychological Theory of Suicide

Childhood physical abuse is a major risk factor for suicide attempt, but factors that moderate this risk remain largely unexamined. Moderated mediation analysis was used with 186 adolescents who responded to the Profiles of Student Life: Attitudes and Behavior survey. Physical abuse increased risk directly and indirectly through reduced self‐esteem. Involvement in youth programs moderated the direct effect. Community service moderated the indirect effect. Results indicate 2 hours per week of involvement in youth programs and 2 hours per week of community service mitigated suicide attempt risk associated with abuse. Providing avenues for youth experiencing abuse to increase their community service and involvement is recommended.     

The Interpersonal–Psychological Theory of Suicide in Adolescents: A Preliminary Report of Changes Following Treatment

This study investigated change in suicide risk in the framework of the interpersonal theory of suicide. Fifty‐four adolescents completed measures of interpersonal needs, acquired capability, depressive symptoms, and suicide risk at entry and exit from treatment. There was a significant drop following treatment in unmet interpersonal needs but not in acquired capability, consistent with the theory. Both change in the interaction between interpersonal needs and in depressive symptoms contributed unique prediction to change in suicide risk. These findings extend the research in understanding changes in suicide risk and inform treatment by suggesting cognitive targets for intervention.     

Race,Offense Type,and Suicide Ideation: Tests of the Interpersonal‐Psychological Theory in Juvenile Offenders

This study evaluated the synergy hypothesis of the Interpersonal‐Psychological Theory of Suicide (IPTS ), which argues thwarted belongingness and perceived burdensomeness are positively interactive in their association with suicide ideation, in a group of juvenile offenders. It also examined whether this prediction is differentially applicable across race/ethnicity or offense type. Participants included 590 adjudicated and confined male juveniles. Regression was used to test the association between suicide ideation and thwarted belongingness, perceived burdensomeness, and their interaction term. Subsequent analyses included tests of group interactions related to race/ethnicity and offense type. No interaction between thwarted belongingness and perceived burdensomeness was observed, despite adequate power. No significant group interactions were observed for race/ethnicity or offense type. However, results did show significant linear relationships between thwarted belongingness, perceived burdensomeness, and ideation, highlighting their potential utility as intervention targets in this at‐risk population. Thus, although the current results are the first to show the basic IPTS risk factors generalize across race/ethnicity and offense type, they also failed to support that those factors were interactive, a primary IPTS claim. The absence of an interaction between thwarted belongingness and perceived burdensomeness suggests their role in suicide ideation for juvenile offenders may be more parsimonious than the IPTS proposes.     

Capable of Suicide: A Functional Model of the Acquired Capability Component of the Interpersonal‐Psychological Theory of Suicide

A functional model of the acquired capability for suicide, a component of Joiner's (2005 ) Interpersonal‐Psychological Theory of Suicide, is presented. A component of Joiner's (2005 ) Interpersonal‐Psychological Theory of Suicide a functional model of the acquired capability for suicide is presented. The model integrates the points discussed by Joiner into a unified and specific conceptualization of acquired capability. Several points are elaborated on, such as the interaction between specific diatheses with life events, the role of short‐term bolstering of the capability for suicide, and how contextual factors moderate the experience of painful and provocative life events; thereby leading to fearlessness and pain insensitivity to the actions and ideas involved in suicide.     

Anxiety Sensitivity Differentially Predicts Factors of Interpersonal–Psychological Suicide Risk: A Consideration of Specificity

Recent studies have identified anxiety sensitivity (AS) as a risk factor for suicidality; however, limited work has been performed to understand this risk within the context of the interpersonal–psychological theory of suicide (IPTS; Joiner, 2005). The current study examined the relationship between overall AS, each AS subfactor (cognitive, social, and physical), and the three IPTS domains (perceived burdensomeness, thwarted belongingness, and acquired capability). While each AS subfactor uniquely predicted one IPTS domain, greater overall AS only predicted greater acquired capability, suggesting that assessment of AS at the subfactor level may offer us more information about an individual's interpersonal suicide risk.     

Childhood Sexual Abuse and Adulthood Parenting: The Mediating Role of Intimate Partner Violence

This study examined the role of intimate partner victimization in mediating the relationship between childhood sexual abuse and adulthood parenting in a community sample of mothers reliant on public assistance (N = 483). Baron and Kenny's (1986 Baron, R. M. and Kenny, D. A. 1986. The moderator–mediator variable distinction in social psychological research: Conceptual, strategic, and statistical considerations. Journal of Personality and Social Psychology, 51: 1173–1182. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) method for establishing mediation was used to address this question. A recent history of intimate partner violence mediated the relationship between childhood sexual abuse and psychological aggression; however, a lifetime history of intimate partner violence did not. Depressive symptomatology was found to mediate the relationship between childhood sexual abuse and parental warmth. The impact of childhood sexual abuse on corporal punishment was indirect through its association with childhood physical abuse and witnessing domestic violence. Implications for research, theory development, and practice are provided.     

A Short‐Term,Prospective Test of the Interpersonal–Psychological Theory of Suicidal Ideation in an Adolescent Clinical Sample

The present prospective study tested a portion of the interpersonal–psychological theory of suicide (IPTS) in an adolescent clinical sample. Participants were 143 adolescents consecutively admitted to a partial hospitalization program who completed assessments at intake and discharge from the program. Results partially supported the IPTS and suggest that (1) perceived burdensomeness may be an important socially based cognition for understanding concurrent risk for suicidal ideation (SI); (2) thwarted belongingness affects depression symptom severity over time, which indirectly predicts SI over a short follow‐up time frame; and (3) the IPTS constructs may function differently in a high‐risk clinical adolescent sample, compared to adults, although findings are preliminary.     

Parental Psychological Control and Childhood Anxiety: The Mediating Role of Perceived Lack of Control

Parental psychological control has been found to relate to the development of childhood anxiety; however, this relation has not been thoroughly examined. The purpose of this study was to understand the nature of the relation between parental psychological control and anxiety symptoms in children, as well as to understand whether this relation is mediated by children’s perceived control. Questionnaires were administered to children ages 8–11. Results indicated a significant relation between parental psychological control and child anxiety symptoms. Results further indicated that this relation was fully mediated by children’s perceptions of how much control they feel they have over events in their lives. These findings suggest that although parental psychological control and a child’s perceived control both contribute to the development of anxiety, it is possible that parental psychological control contributes to the development of anxiety by affecting a child’s perception of control.     

Perceived Racism and Suicide Ideation: Mediating Role of Depression but Moderating Role of Religiosity among African American Adults

Suicide is a public health problem for African Americans who are young and of working age. The purpose of this study was to examine mediated and moderated effects of perceived racism on suicide ideation in a community sample of 236 African American men and women. Measures of suicide ideation, depression symptoms, intrinsic/extrinsic religiosity, and perceived racism were administered. Perceived racial discrimination was directly and indirectly associated with suicide ideation. For participants who reported low levels of extrinsic religiosity, the mediated effect of perceived racism (via depression symptoms) was significant. These findings provide some insight into suicide vulnerability for specific subgroups of African Americans.     

Hope and the Interpersonal‐Psychological Theory of Suicidal Behavior: Replication and Extension of Prior Findings

The interpersonal‐psychological theory of suicidal behavior (IPTS; Joiner, 2005) posits that suicidal behavior occurs when an individual has a desire for death (due to the combination of perceived burdensomeness and thwarted belongingness) in addition to an acquired capacity for suicide, which is present when the individual has a low fear of death and high pain tolerance. Previous research has demonstrated an expected negative relation between trait hope and perceived burdensomeness and thwarted belongingness, as well as a more perplexing finding that hope is positively associated with the acquired capability. In a sample of 230 college students, measures of the three components of the IPTS were administered, along with measures of hope, depression, and painful and/or provocative events. Hierarchical regression analyses replicated the previously found associations between hope and burdensomeness and belongingness while controlling for depression and demographic variables. The positive association between hope and acquired capacity was also replicated, but a mediation analysis demonstrated that the effect was statistically accounted for by distress tolerance. The results further support the incremental validity of hope as a consideration in suicide risk assessments and suggest that hope may serve as a protective factor with respect to suicidal desire.

A Prospective Examination of the Interpersonal‐Psychological Theory of Suicidal Behavior Among Psychiatric Adolescent Inpatients

The challenge of identifying suicide risk in adolescents, and particularly among high‐risk subgroups such as adolescent inpatients, calls for further study of models of suicidal behavior that could meaningfully aid in the prediction of risk. This study examined how well the Interpersonal‐Psychological Theory of Suicidal Behavior (IPTS)—with its constructs of thwarted belongingness (TB), perceived burdensomeness (PB), and an acquired capability (AC) for lethal self‐injury—predicts suicide attempts among adolescents (N = 376) 3 and 12 months after hospitalization. The three‐way interaction between PB, TB, and AC, defined as a history of multiple suicide attempts, was not significant. However, there were significant 2‐way interaction effects, which varied by sex: girls with low AC and increasing TB, and boys with high AC and increasing PB, were more likely to attempt suicide at 3 months. Only high AC predicted 12‐month attempts. Results suggest gender‐specific associations between theory components and attempts. The time‐limited effects of these associations point to TB and PB being dynamic and modifiable in high‐risk populations, whereas the effects of AC are more lasting. The study also fills an important gap in existing research by examining IPTS prospectively.
