Risk factors of suicidal behaviors in a high-risk longitudinal veteran sample: A network analysis

Introduction Suicide is a substantial public health burden, particularly among veterans. Risk factors have been delineated for suicide; however, the dynamic interrelations between risk factors have not been fully examined. Such research has the potential to elucidate processes that contribute to suicide risk between individuals with a past suicide attempt (attempters) and those without a […]

Proximal correlates of suicidal ideation and behaviors: A test of the Interpersonal-Psychological Theory of Suicide

Objective The interpersonal-psychological theory of suicide hypothesizes proximal causes of suicidal ideation and behaviors; however, past studies have generally tested distal relations. The present study tested the proximal nature of the theory’s hypotheses. Methods A repeated-measures design collected daily survey data on the theory constructs over 90 days from 206 (150 women) college students with previous […]

Suicidal ideation in elite schools: A test of the Interpersonal Theory and the Escape Theory of suicide

Objective The present study compared the ability of two contemporary theories of suicidal behavior—the interpersonal and escape theories of suicide—to predict suicidal ideation. The interpersonal theory proposes that the interaction of perceived burdensomeness and thwarted belongingness predicts suicidal ideation. The escape theory proposes that feelings of failure predict suicidal ideation and that escape motivation mediates […]

Testing basic assumptions of the Interpersonal Needs Questionnaire-15 in a sample of clinically depressed and suicidal youth

Objective Suicide is a leading cause of death in adolescence. The mechanisms of adolescent suicidality, however, are not fully understood. Although the Interpersonal-Psychological Theory of Suicide, as assessed by the Interpersonal Needs Questionnaire-15 (INQ), may be a promising framework, systematic study of its utility during adolescence is lacking. Method To this end, we utilized factor […]

Integrating minority stress theory and the interpersonal theory of suicide among sexual minority youth who engage crisis services

Objective The present study sought to integrate minority stress theory (MST) and the interpersonal theory of suicide (ITS) to better understand high rates of suicide among sexual minority youth (SMY). To date, the ITS and MST have largely advanced independently from one another even though the research base for each theory contains gaps that the […]

Performance of the interpersonal needs questionnaire in adolescent clinical samples: Confirmatory factor analyses and evaluation of measurement invariance

Objective This study evaluated the factor structure, internal consistency reliability, construct and criterion validity, and measurement invariance of the Interpersonal Needs Questionnaire (INQ) among adolescents. Method Participants (N = 539) included three distinct samples of youth drawn from two outpatient psychology clinics and an inpatient psychiatric unit. The combined sample was 63.3% female and had a mean […]

Investigation of the interpersonal theory of suicide in the context of attention-deficit/hyperactivity disorder symptomatology and suicide ideation

Objective The current study examines components of the Interpersonal Theory of Suicide as mediators of the association between attention-deficit/hyperactivity disorder (ADHD) symptoms and suicide ideation in college students with elevated depressive symptoms. Specifically, indirect effects of perceived burdensomeness and thwarted belongingness were simultaneously evaluated on the association between self-reported ADHD symptoms and suicide ideation, controlling […]

Incorporating psychopathology into the interpersonal-psychological theory of suicidal behavior (IPTS)

Background The interpersonal-psychological theory of suicidal behavior (IPTS) posits that the joint presence of perceived burdensomeness (PB), thwarted belongingness (TB), and capability for suicide (CS) is necessary for suicide attempt. Emerging evidence demonstrates these effects are not consistently observed. Psychopathology may independently impact on the explanatory power of the IPTS constructs. Aims The aims of […]

Acquired capability for suicide among Belgian and Australian University students: Psychometric properties of the German capability for suicide questionnaire and a test of the interpersonal theory of suicide

Objective The Interpersonal Theory of Suicide (IPTS) posits fearlessness of death and pain tolerance as two components of suicide capability. The German Capability for Suicide Questionnaire (GCSQ) is the first measure of both these components, but few data are available on its psychometrics. We (a) examined the psychometric properties of the GCSQ and used it to test […]

The applicability of the interpersonal–psychological theory of suicide among community-dwelling older persons

Introduction This study examined the application of the interpersonal–psychological theory of suicide to community-dwelling older persons in South Korea. Methods A cross-sectional study design was used. The data were collected by surveying 200 older persons (117 female, 83 male) aged over 65 years at welfare centers for older persons. The Interpersonal Needs Questionnaire, the Suicidal Ideation […]

Implementing the interpersonal theory of suicide to improve outcomes in suicidal adolescents: A pilot trial

Introduction The Interpersonal Psychological Theory of Suicide proposes two constructs that serve as a final common pathway to suicidal ideation: thwarted belongingness and perceived burdensomeness. There have been few translations of this theory to clinical care. This study aimed to address this limitation by targeting burden cognitions with novel interventions. Methods A pilot clinical trial […]

Masculinity’s association with the interpersonal theory of suicide among military personnel

Objective Given that the majority of those who die by suicide are male, masculine traits have been examined as a potential link to the development of capability for suicide. However, research has not examined if such traits influence suicidal desire (i.e., thwarted belongingness, perceived burdensomeness). This study examined the influence of stereotypically masculine traits of […]

A longitudinal examination of the interpersonal theory of suicide for predicting suicidal ideation among LGBTQ+ youth who utilize crisis services: The moderating effect of gender

Despite high rates of suicide among LGBTQ+ youth, the interpersonal theory of suicide (IPTS) has rarely been examined in this population. The current study utilized a longitudinal design to examine whether perceived burdensomeness and thwarted belongingness independently and simultaneously predicted higher levels of suicidal ideation over time in a sample of LGBTQ+ youth who utilized […]

Thwarted belongingness predicts greater neural reactivity to a novel social exclusion image set: Evidence from the late positive potential

Introduction Thwarted belongingness (TB) is among the most well-researched risk factors for suicidal ideation (SI). Yet, there is little research examining neural mechanisms underlying this construct. The present study used a novel social exclusion image set in concert with the late positive potential (LPP) to test the role of neural reactivity social exclusion in TB […]

Factors contributing to honor-endorsing men’s suicide capability: Firearm ownership, practical capability, and exposure to painful and provocative events

Objective White men in U.S. cultures of honor die by suicide at greater rates than other demographic groups. This finding has been attributed to factors such as the prevalence and use of firearms in men’s suicide in honor states, as well as motivational risk factors (e.g., thwarted belongingness). Other features of honor cultures (e.g., physical […]

Distress tolerance as a moderator of the dynamic associations between interpersonal needs and suicidal thoughts

Background Identifying the interaction between dispositional and dynamic risk factors is necessary in understanding, predicting, and managing suicide risk. Interpersonal factors have consistently been linked to suicidal ideation over short-term periods. Additionally, distress tolerance may be a relevant dispositional protective factor against stressful events. Methods Seven hundred and seventeen psychiatric inpatients (Male = 30.31%, Average Age = 40.71 years, Min = 14, […]

Examining psychometric properties of the Interpersonal Needs Questionnaire among college students in India

Background With the second-highest population in the world, suicide-related deaths in India are high, and adults under 30 are particularly at an increased risk. However, empirical examinations of factors contributing to suicide in India and assessments of reliability and validity of self-report measures assessing these constructs are rare. Aims The present study examined the psychometric […]

Awareness isn’t saving lives: An experimental exploration of suicide risk reduction methods for emerging adults

Objective Suicide prevention campaigns commonly employ brief informational materials aimed at emerging adults. Are such programs helpful, and do design characteristics yield differences in user outcomes? Literature is reviewed from the interpersonal theory of suicide, escape theory, and terror management theory, to inform our experimental design. Method Participants (n = 977 MTurk emerging adults) reported demographics and suicide […]

Application of minority stress and the interpersonal theory of suicide in bisexual+ versus gay/lesbian young adults

Introduction Sexual minority young adults are at increased risk for suicidal ideation (SI) compared with heterosexual young adults. Though several frameworks exist to explain the development of suicide risk, including the Interpersonal Theory of Suicide (IPTS) and the Minority Stress Model, few studies have examined these frameworks simultaneously. This study examines these frameworks longitudinally among […]

Social network subtypes among socially disconnected older adults at risk for suicide: A latent class analysis

Objectives We sought to characterize the social networks of older adults who report feeling lonely or like a burden on others, psychological states that are associated with risk for suicide according to the Interpersonal Theory of Suicide. Methods We used a latent class analysis to identify distinct groups of older adults based on social network […]

Assessing the clinical utility of MMPI-2- RF interpersonal theory of suicide proxy indices in psychiatric hospitalization setting

Introduction The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF Ben-Porath & Tellegen, 2008/2011) has been applied to suicide risk assessment through derived proxy indices of perceived burdensomeness, thwarted belongingness, and the acquired capability for suicide (Anestis et al., 2018, Joiner, 2005). However, limited research has examined the clinical utility of these proxy indices outside the outpatient […]

Longitudinal mediation by perceived burden of the pathway from thwarted belonging to suicidal ideation

Introduction Whereas the interpersonal theory of suicide entails the assumption that thwarted belongingness and perceived burdensomeness are equally important, mutually moderating, proximal causes of active ideation, evidence suggests these may not be co-moderating processes. We tested an alternative perspective, hypothesizing that burden mediates the longitudinal relationship of thwarted belonging with active ideation. Methods A 6-week, […]

Substance use frequency relates to suicidal ideation through perceived burdensomeness and to suicide attempts through capability for suicide

Background Although substance use has been linked to both suicidal ideation and suicide attempts, the factors underlying these relations remain unclear. The Interpersonal-Psychological Theory of Suicide (ITS) provides a framework for understanding how substance use may increase suicide risk. The purpose of the current study was to examine if frequency of substance use is indirectly […]
