Defeat, entrapment, and hopelessness : clarifying interrelationships between suicidogenic constructs

Psychological theories of suicide posit conceptually similar constructs related to the development of suicidal thinking. These constructs often evince high-magnitude interrelationships across studies. Within these theories, defeat, entrapment and hopelessness standout as conceptually and quantitatively similar. Theoretical improvements may be facilitated through clarifying the subscale and item-level similarities among these constructs. Factor analytic and phenomenological work has demonstrated equivocal evidence for a distinction between defeat and entrapment; hopelessness is not typically analyzed together with defeat and entrapment despite evidence of large-magnitude interrelationships. This study explored the interrelationships among the foregoing constructs within a sample of undergraduate students (N = 344) from two universities within the Southeastern United States. Participants, oversampled for lifetime history of suicidal ideation and attempts, completed an online cross-sectional survey assessing defeat, entrapment, hopelessness and SI. Exploratory factor and parallel analyses demonstrated support for a one factor solution when analyzed at subscale level of the three measures as well as when all items of the three measures were analyzed together. Ad hoc exploratory structural equation modeling (ESEM) bifactor results evinced support for the existence of a single, general factor at the item level. Item level communalities and bifactor fit indices suggest that hopelessness may be somewhat distinct from defeat and entrapment. Clinical and theoretical implications are discussed in the context of study limitations

INTERNAL ENTRAPMENT AND FEARLESSNESS ABOUT DEATH AS PRECIPITANTS OF SUICIDAL THOUGHTS AND PLANNING IN THE CONTEXT OF POST-TRAUMATIC STRESS DISORDER (PTSD)

The post-traumatic stress disorder (PTSD) and suicidal thoughts and behaviors (STB) relationship has been extensively studied but potential explanatory mechanisms remain inconclusive. Entrapment is one variable that evinces a theoretical and empirical mechanistic relationship with PTSD and STB. Further, entrapment and fearlessness about death (FAD) have not been linked but are hypothesized to interact in a way that facilitates vulnerability for intense suicidal thinking and potentially suicidal behavior. The current study examined the indirect effect PTSD symptoms have on suicidal ideation, planning, and likelihood of future suicide attempt through both internal (IE) and external entrapment (EE), moderated by levels of FAD. The sample consisted of both military service members and civilians recruited from six primary care clinics within five military installations across the United States (N=2,690). Results of the moderated mediation analyses indicated an indirect relationship between PTSD and both past month SI and suicide planning through IE but not EE at low, moderate, and high levels of FAD. This indirect relationship was replicated for the association between PTSD and self-rated likelihood of a future suicide attempt through both IE and EE, but at only moderate and high levels of FAD. Phenomenological implications are discussed, including IE as a potential mechanism of action in the transition from PTSD to SI and FAD as necessary to potentiate suicidal planning for those experiencing IE

Ethnic Identity and Suicide Risk among Hispanic/Latinx Young Adults: The Impact of Perceived Burdensomeness and Thwarted Belongingness

Hispanic/Latinx college students experience SI/behaviors at high rates, yet there is a dearth of research on suicide risk and sociocultural correlates of suicide risk among Hispanic/Latinx individuals. This study examined the impact of ethnic identity on suicide risk among 63 Hispanic/Latinx young adults. Further, we tested a model in which ethnic identity is integrated into the Interpersonal Psychological Theory of Suicide Behavior (IPTS). Lower levels of ethnic identity attachment were related to greater suicide risk. Further, moderated mediation analyses indicated that perceived burdensomeness mediated the relation between ethnic identity and suicide risk at higher levels of thwarted belongingness. Findings highlight the importance of sociocultural factors in understanding the utility of the IPTS model among Hispanic/Latinx individuals

Suicide Cognitions Scale: Psychometric Support in a Community Sample Using Bifactor Modeling and Altered Item Content

The Suicide Cognitions Scale (SCS) measures suicide-related beliefs proposed by the Fluid Vulnerability Theory. A recent investigation of a revised version of the SCS (i.e., SCS-R) which omits items explicitly referencing suicide has indicated that the measure is highly influenced by a general factor and may be useful for distinguishing severity levels of suicidal thoughts and behaviors; however, limited concurrent validity studies with a range of suicide-related experiences have been conducted. As such, this study replicated and extended previous psychometric research on the SCS-R in an online survey study with a community sample of = 10,625 U.S. adults. Results confirmed the unidimensional structure of the SCS-R. Logistic regression analyses indicated that the total score of the SCS-R is useful in distinguishing varying levels of suicidal thoughts and behaviors such as past-month planning for suicide without attempt versus past-month suicide attempt. Implications and limitations are discussed

Internal entrapment and fearlessness about death as precipitants of suicidal thoughts and planning in the context of post-traumatic stress disorder

BACKGROUND: The relationship between post-traumatic stress disorder (PTSD) and suicidal thoughts and behaviors (STB) has been extensively studied but explanatory mechanisms remain inconclusive. Entrapment is one variable that evinces a mechanistic relationship with PTSD and STB. The current study examined the indirect effect of PTSD screen on suicide ideation (SI), planning, and likelihood of future suicide attempt through internal (IE) and external entrapment (EE), moderated by levels of fearlessness about death (FAD). METHOD: The cross-sectional sample consisted of military service members and civilians recruited from primary care clinics across the United States (N = 2690). RESULTS: Moderated mediation models indicated an indirect relationship between a positive PTSD screen, past-month SI, and past-month suicide planning through IE but not EE at low, moderate, and high levels of FAD. These relationships were replicated for the association between positive PTSD screen and concurrent self-rated likelihood of a future suicide attempt through both IE and EE at moderate and high levels of FAD. CONCLUSIONS: Phenomenological implications are discussed, including IE as a mechanism of action in the PTSD/SI pathway and FAD as necessary to potentiate suicidal planning for those experiencing IE
