Objectives: Identify interventions offered for children bereaved by parental suicide, investigate reported effectiveness and explore the acceptability of identified interventions.

Method: Six electronic databases were systematically searched for primary studies investigating intervention effectiveness and acceptability, (August 2011 to June 2023). Eligibility required inclusion of participants bereaved by parental suicide during childhood among sample populations. Methodological quality was evaluated applying JBI critical appraisal tools. Narrative synthesis was conducted using parallel-results convergent design.

Results: Of the 22 eligible reports, 19 articles reported on 12 manual-based supports provided during childhood; three papers described users' experiences of various specified intervention types offered following childhood loss. Twenty-one studies reported on interventions offered for heterogeneous participant groups that included children bereaved by parental suicide. Time from loss to intervention generally included both recent (1 < 30mths) and more distant loss, with just one intervention described as solely for recently bereaved children. Eight interventions (n = 12 studies) demonstrated significant positive effects (p < 0.05), for maladaptive grief, mental health, quality of life. Only one study investigated suicide-related outcomes. Qualitative findings (n = 8 studies) facilitated development of four acceptability themes: Perceived utility, Relationships, Components and Delivery.

Conclusions: Heterogeneity in causes of loss/trauma and relationships with the deceased limit specific conclusions regarding effectiveness/acceptability of reviewed interventions for children bereaved by parental suicide. Few sub-group analyses of effects were reported, and qualitative evidence specifically from children bereaved by parental suicide was limited. Further research is recommended regarding mixed-user interventions, specifically for children bereaved by parental suicide.

Despite the far-reaching impact of suicide on our communities, suicide prevention has historically focused on distally related risk factors for suicidality, which gives us an incomplete picture of how someone comes to make a suicide attempt. Instead, our focus needs to extend to research that explains the maintenance and progression from an emotional state to a suicidal crisis. One such factor, rumination, may create or worsen suicidal thinking by amplifying the distress associated with negative thoughts. Ruminative thoughts are often described as difficult to control, and people may think about suicide as an escape from these uncontrollable thoughts. The current study examined the relationship between severity of lifetime suicidal thinking and certain forms of rumination (i.e., brooding, reflection, anger rumination, and suicidal rumination) in a sample of 145 undergraduate students with suicidal thoughts. For each form of rumination that was related to suicidal thinking, we then examined whether that relationship was accounted for by perceived uncontrollability of one's own thoughts. We found that all forms of rumination were related to severity of lifetime suicidal thinking, as well as heightened perceived inability to control one's own thoughts. This thought control inability helped account for the relationships between brooding, reflection, and anger rumination with severity of suicidal thinking, but did not play a role in the relationship between suicidal rumination and suicidal ideation severity. Clinicians should be aware of the impact ruminative thoughts may have on suicidal thinking. More research needs to be done to replicate and extend these effects.

Objective: Suicide remains a public health problem within the United Kingdom (UK) and globally. Impulsivity is a key risk factor within the Integrated Motivational-Volitional Model (IMV) of Suicide warranting further study. The current study applied a multi-dimensional impulsivity framework (UPPS-P) to differentiate suicidality subgroups within an IMV framework (i.e., no suicidal behavior, suicidal ideation only, and suicide attempt). Impulsivity subscales were evaluated as moderators of the suicidal ideation-future suicide attempt link.

Method: Adults living in the UK (N = 1027) completed an online survey addressing demographics, impulsivity, psychological distress, and lifetime suicidal behavior. We used analysis of variance (ANOVA) and linear regression with simple slopes analyses to investigate study objectives.

Results: Data analyses revealed that: (1) four impulsivity subtypes (negative urgency, positive urgency, lack of premeditation, sensation-seeking) differentially distinguished suicidal behavior groups; (b) negative urgency, positive urgency, and lack of premeditation were meaningfully associated with suicide outcomes, and (c) negative urgency served as a moderator of the suicidal ideation-future attempt link.

Conclusions: Urgency, regardless of positive or negative valence, is important for understanding differences in lifetime suicidal behavior. Sensation-seeking may play a protective role for direct suicidal behavior. Negative urgency may be the most prominent aspect of impulsivity when considered as an IMV moderator. Findings are contextualized with respect to impulsivity and IMV frameworks. Clinical implications involve accounting for negative urgency in suicide risk assessment and intervention.

Background: Depression, loneliness, and alcohol use disorder are associated with suicide ideation. The ongoing COVID-19 pandemic has challenged our social structures with social distancing and isolation policies implemented worldwide, severely restricting social interactions. Studies regarding the effects of the pandemic are starting to shed light on the harmful psychological effects of these policies.

Aims: This study aims to identify whether the increase in suicidal ideation among college students (mostly young adults) during the pandemic was due to the known risk factors of loneliness, depression, alcohol use disorder, social media addiction, and other background variables.

Method: Nine hundred and eleven college students completed self-report questionnaires assessing suicidal risk, depressive symptoms, loneliness, excessive alcohol use, and social media use.

Results: During the pandemic suicidal ideation was associated with loneliness (χ² = 54.65, p < 0.001), depressive symptoms (χ² = 110.82, p < 0.001), alcohol use disorder (χ² = 10.02, P < 0.01) and social media addiction (χ² = 13.73, P < 0.001). Being single [OR = 2.55; p < 0.01], and self-identifying as a non-heterosexual [OR = 2.55; p < 0.01] were found to constitute additional risk factors.

Limitations: The structural nature of quantitative self-report scales does not offer the flexibility of gaining a deeper understanding of causes, specific to particular circumstances that may lead participants to ideate on suicide, even briefly.

Conclusions: Social distancing and isolation policies during the COVID-19 pandemic constitute an additional factor in the risk for suicide ideation.

Objective: The present study seeks to add to the existing literature by determining if having a plan for suicide, is associated with an individual's self-reported likelihood of attempting suicide in the future.

Method: Data came from a sample of 97 United States Army personnel with past week ideation or lifetime attempt history. Assessments were collected at baseline, 1-month, 3-month, and 6-months.

Results: Self-reported likelihood of attempting suicide in the future was not associated with the presence of a plan for suicide overall or a plan with a specific method (i.e., firearm, cutting/scratching, and medication).

Discussion: Although a plan for suicide is commonly thought to indicate elevated risk our findings suggest that presence or absence of suicide plans is not associated with more self-reported likelihood of a future suicide attempt.

Objective: The aim of this study was to investigate sex differences in suicide ideation and attempt at different career stages and test hypotheses derived from the Interpersonal Theory of Suicide (IPTS) in a sample of veterinarians.

Method: The sample of currently practicing veterinarians used for this study (N = 10,319) was derived from a larger sample. Participants completed an online self-report questionnaire.

Results: As predicted, women generally had a higher prevalence of suicide ideation and attempt across career stages, except men and women showed similar rates of suicide attempt after veterinary school. Contrary to hypotheses, no interaction effects between IPTS variables were observed. However, perceived burdensomeness, thwarted belongingness, and hopelessness exhibited the main effects of suicide ideation, and there were main effects of perceived burdensomeness and hopelessness on suicide attempt. Compared with perceived burdensomeness and thwarted belongingness, hopelessness had a relatively more robust relationship with suicide ideation. We also found a significant relationship between fearlessness about death and suicide attempt, but no relationship between self-reported pain tolerance and suicide attempt.

Conclusions: Some of our findings were consistent with the IPTS while others were not. Future research would benefit from a longitudinal examination of suicidality in veterinarians.

Background: Suicide is the 10th leading cause of death among Australian males. Despite the cultural diversity in Australia, there is a significant research gap in knowledge of suicidal behavior among Australian males from ethnically and culturally diverse backgrounds. The study aimed to estimate the prevalence and risk of suicidal behaviors among Australian males based on ethnicity, with an emphasis on those from ethnic-minority backgrounds.

Methods: We used data from the first wave of the Australian Longitudinal Study on Male Health. Multiple logistic regression models were used to determine the risk of suicidal behavior (lifetime suicide attempt, lifetime suicidal ideation, recent suicidal ideation) by ethnicity.

Results: Among ethnic minority males, Pacific Islander males also had the highest prevalence of lifetime suicide attempts (12.2%), while Middle Eastern (2.3%) and South-/North-East Asian males (2.9%) had the lowest rates. South American males had the highest recent suicidal ideation (18.2%), followed by Pacific Islanders (14.2%). The highest prevalence of lifetime suicidal thoughts was reported among males of mixed ethnicity (23.0%), followed by South American (14.6%) and Pacific Islander (13.5%) males. Most ethnic-minority groups had a lower risk of lifetime suicidal ideation compared with Australian males. Evidence regarding differences in recent suicidal ideation and lifetime suicide attempts between ethnic-minority and Australian-background males was inconclusive.

Conclusion: Evidence was found of differences in suicidal behaviors among Australian males based on ethnicity. Future research should use inclusive methodologies to confirm these associations and explore the underlying factors contributing to higher rates of suicidal behavior in specific populations.

Objective: Elevated rates of suicidal ideation (SI) and suicide attempts (SA) among youth, particularly multiply marginalized youth, are occurring in the context of youths' access to household firearms. Research examining how perceived access to firearms is related to SI and SA among youth with marginalized identities is limited and often neglects to consider intersectionality. This study explored how intersecting social identities and positions, access to firearms, and socio-structural factors were associated with SI and SA for youth.

Method: The analytic sample (N = 17,794) included 7-12^th grade students who participated in the 2021 Dane County Youth Assessment. Exhaustive CHAID - a decision tree matrix approach - examined all possible combinations of self-reported sociodemographic characteristics (gender identity, sexual identity, racial identity, grade, and firearm access) and socio-structural variables (bias-based bullying, school belongingness, and social pressure) to predict mutually exclusive groups of youth based on past-year SI and SA.

Results: SI and SA was most prevalent among intersectional groups with multiply marginalized identities and access to firearms. Socio-structural factors, including bias-based bullying victimization, lack of school belongingness, and social pressure, were characteristic of groups with higher prevalence of SI and SA.

Conclusions: While the marginalized youth in this sample have lower access to firearms, the prevalence of SI and SA was highest among multiply marginalized youth who reported access to firearms in the context of bias-based bullying, social pressure, and a lack of school belongingness. Youth suicide prevention efforts would be strengthened by policies that address firearm access and improve the school environment.

Objective: Suicide disproportionately affects low- and middle-income countries and evidence regarding prevention approaches developed in high income countries may not be applicable in these settings. We conducted an umbrella review to assess whether the conclusions of suicide prevention systematic reviews accurately reflect the studies contained within those reviews in terms of setting generalizability.

Methods: We conducted database searches in PubMed/Medline, Embase, PsycInfo, PsychExtra, OVID global health, and LILACS/BECS. We included systematic reviews with the outcome of suicide, including bereavement studies where suicide death was also the exposure.

Results: Out of the 147 reviews assessed, we found that over 80% of systematic reviews on suicide deaths do not provide an accurate summary of review findings with relation to geographic relevance and ultimately generalizability.

Conclusion: Systematic reviews are often the resource used by practitioners and policymakers to guide services. Misleading reviews can detrimentally impact suicide prevention efforts in LMICs. We call for systematic reviewers to be responsible when generalizing the findings of their reviews particularly in the abstracts.
