Abstract
OBJECTIVE Increased suicidality and suicide deaths among veterans of the Australian Defence Force have gained recent prominence. A systematic scoping review was conducted to identify, summarise and synthesise the existing literature relating to Australian veteran suicide and suicidality, with the objective of identifying future research priorities. METHODS We conducted a PRISMA-compliant systematic search on PubMed/MEDLINE, Embase and CINAHL databases for all manuscripts reporting primary data on suicide and suicidality in Australian veterans. The search was supplemented by grey literature and a search of reference lists. Manuscripts of any study type, published in the English language since the Vietnam era, were eligible for inclusion. RESULTS A total of 26 articles and reports, utilising a variety of mostly quantitative approaches, were included in the review. Findings, especially in larger and more recent studies, indicate increased suicidality in the veteran population. Suicide deaths appeared to increase with transition out of the military. Mental illness was identified as an important risk factor for suicide and suicidality. Current service was identified as a protective factor against suicide. There was mixed evidence regarding the impact of operational deployment on suicide and suicidality. CONCLUSIONS Gaps were identified in relation to the relative contributions to risk from transition, the various psychosocial correlates (for example, relationships, finances, employment), pre-service factors and the extent to which these are causal or mediating in nature. A better understanding of health service utilisation would also aid in targeting preventive efforts. Future research in these areas is warranted.

Abstract
BACKGROUND Insomnia is associated with suicide risk in civilian and military populations. Thwarted belongingness is proposed as a mediator of this relationship under the Interpersonal Theory of Suicide (IPTS). The present study explored how insomnia relates to suicidal ideation in conjunction with thwarted belongingness among civilians, Service members, and Veterans. METHODS Data from the Military Suicide Research Consortium for N = 6556 individuals (6316 with non-missing suicidal ideation status) were divided into 4 subgroups: civilians, never deployed Service members, previously deployed Service members, and Veterans. Robust Poisson models evaluated the associations between insomnia severity/subtype and current suicidal ideation, with bootstrap mediation models assessing thwarted belongingness as a mediator. RESULTS A 5-point increase in insomnia severity was associated with a 38% increased risk for current suicidal ideation among civilians, a 56% greater risk among never deployed Service members, an 83% greater risk among previously deployed Service members, and a 37% greater risk among Veterans. Moreover, active Service members showed greater associations between difficulty falling asleep and staying asleep with suicidal ideation than civilians. These associations were independent of covariates and only mediated by thwarted belongingness among Veterans. CONCLUSIONS The relationship between insomnia and suicide is not purely explained by thwarted belongingness except among Veterans. Future research should explore additional psychological and neurobiological mechanisms connecting insomnia and suicidality.

Abstract
Suicide is a preventable health problem. Multiple definitions and inconsistent use of the term suicidality can result in failure to properly recognize suicide risk and behavior and confuses suicide research. Clarification of the suicidality concept is needed to facilitate the care for individuals at risk for suicide. Using Rodgers' evolutionary concept analysis method, this analysis describes the breadth and scope of the suicidality concept. Findings indicate suicidality covers a spectrum of suicidal risk and levels of emotional suffering and intent. The analysis does not draw definite conclusions, but outlines a direction for further research.

Abstract
The current review provides a quantitative synthesis of the empirical literature on sleep disturbance as a risk factor for suicidal thoughts and behaviors (STBs). A systematic search of PsycINFO, MEDLINE, and the references of prior reviews resulted in 41 eligible studies included in this meta-analysis. Sleep disturbance, including insomnia, prospectively predicted STBs, yielding small-to-medium to medium effect sizes for these associations. Complicating interpretation of these findings however, is that few studies of suicidal ideation and suicide attempts, as well as none of suicide deaths, assessed short-term risk (i.e., employed follow-up assessments of under a month). Such studies are needed to evaluate current conceptualizations of sleep dysregulation as being involved in acute risk for suicidal behavior. This want of short-term risk studies also suggests that current clinical recommendations to monitor sleep as a potential warning sign of suicide risk has a relatively modest empirical basis, being largely driven by cross-sectional or retrospective research. The current review ends with recommendations for generating future research on short-term risk and greater differentiation between acute and chronic aspects of sleep disturbance, and by providing a model of how sleep disturbance may confer risk for STBs through neuroinflammatory and stress processes and associated impairments in executive control.

Suicide-related interpersonal needs of young Iranian people: A preliminary validation of thwarted belongingness and perceived burdensomeness constructs. Clin Psychol Psychother 2020; 28:422-437. [PMID: 32852132 DOI: 10.1002/cpp.2507] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Revised: 08/23/2020] [Accepted: 08/24/2020] [Indexed: 12/28/2022]
Abstract
The aim of the current study was to validate the Interpersonal Needs Questionnaire (INQ-15) and to test its reliability in Persian-speaking Iranian undergraduate students. In this cross-sectional study, 485 undergraduate students (age: 20.66 ± 1.42, 60% female) were assessed on the two subscales of perceived burdensomeness (PB) and thwarted belongingness (TB) and the Suicide Behavior Questionnaire-Revised (SBQ-R). Exploratory structural equation modelling (ESEM) confirmed the construct validity of INQ-14, excluding INQ#9. In addition, INQ#8, articulated in an equivalent Persian phrasing, loaded well on TB. The measurement model tested by confirmatory factor analysis (CFA) suggested INQ#11 to be eliminated, resulting in INQ-13-P to consist of PB and TB-7. The internal consistency and convergent/discriminant validity were established. The concurrent validity of PB was solidly established in terms of past year suicidal ideation (PY-SI) above and beyond anxiety, depression, prior suicidality, and TB-7. The effect of PB on PY-SI was stronger, where prior suicidality had already occurred or the perceived likelihood of future suicide (PLFS) was high. Moreover, TB-7 could only indicate PY-SI, where prior suicidality had already occurred or PLFS was high, albeit when PB was omitted. The interaction term was significant; however, beyond anxiety and depression, the effect of TB-7 on PY-SI was significant where PB was very high (n = 40, 8.25%). Therefore, future studies can utilize INQ-13-P as a valid and reliable instrument in Persian-speaking populations. However, further studies should examine the construct validity of TB and its relationship with suicide ideation in different populations.
