BACKGROUND:Suicide is a leading cause of death among young males in Australia. Tomorrow Man's "Breaking the Man Code" workshops aim to challenge potentially harmful masculine norms and promote positive attitudes towards help-seeking among adolescent boys in schools. METHODS:Our stratified cluster randomized trial was undertaken with 1225 boys (mean (SD) age = 15.04 (0.74) years) across 24 Australian secondary schools: 13 randomized to intervention, 11 to waitlist control. Primary outcome was mean change in intentions to seek help for personal or emotional problems 4 to 8 weeks from baseline. Secondary outcomes included conformity to masculine norms, depression risk, perceived social support, and quality of life. Purpose-designed closed-ended questions captured other behavioral and attitudinal changes. The trial was prospectively registered with ANZCTR. RESULTS:Estimated mean change in scores from baseline between the two groups on the primary outcome was -0.07 (95% confidence interval: -1.75, 1.62; p = 0.937). Purpose-designed questions revealed increased help-offering, connection with friends, and some potential barriers to change. CONCLUSIONS:Further research is needed to understand the impacts of school-based interventions for boys. TRIAL REGISTRATION:Prospectively registered with ANZCTR: ACTRN12620001134910.

Objective Each year approximately 3,000 Australians die by suicide. We estimated the population attributable risk for identified target populations to provide evidence on how much of the overall burden of suicide in the Australian population is experienced by each of them.Methods We identified 17 demographic and clinical target populations at risk of suicide and calculated the population attributable fraction (PAF) using a single or pooled suicide risk and the proportional representation of each target population within Australia.Results Large PAF estimates were found for men (52%, 95% confidence interval (CI) 51%-53%), people bereaved by suicide (35%, 95% CI 14%-64%), people with a mental health or behavioural condition (33%, 95%CI 17%-48%), people with a chronic physical condition (27%, 95%CI 18%-35%), adults aged 25-64 years (13%, 95%CI 12%-14%), LGB populations (9%, 95%CI 6%-13%), offenders (9%, 95%CI 8%-10%), and people employed in blue collar occupations (8%, 95%CI 4%-12%).Limitations The PAF is limited by assumptions, namely, that risk factors are independent, and that the relationship between risk factors and outcomes are unidirectional and constant through time.Conclusions and implications for public health Considerable reductions in the overall suicide rate in Australia may occur if risk factors are addressed in identified populations with large PAF estimates. These estimates should be considered as an adjunct to other important inputs into suicide prevention policy priorities.

Background: Psychosocial interventions following self-harm in adults, in particular cognitive behavioral therapy (CBT), can be effective in lowering the risk of repeated self-harm. Aims: To evaluate the cost-effectiveness of CBT for reducing repeated self-harm in the Australian context. Method: The current study adopted the accessing cost-effectiveness (ACE) approach using return-on-investment (ROI) analysis. Uncertainty and sensitivity analyses (Sas) tested the robustness of the model outputs to changes in three assumptions: general practitioner referral pathway (SA1), private setting intervention delivery (SA2), and training costs (SA3). Results: The intervention produced cost savings of A$ 46M (95% UI -223.7 to 73.3) and A$ 18.3M (95% UI -86.2 to 24.6), subject to the effect of intervention lasting 2- or 1-year follow-up. The ROI ratio reduced to 5.22 in SA1 (95% UI -10.1 to 27.9), 2.5 in SA2 (95% UI -4.8 to 13.3), and 5.1 in SA3 (95% UI -9.8 to 27.8). Limitations: We assumed that the effectiveness would reduce 50% within 5 years in the base case, and we used Australian data and a partial social perspective. Conclusions: The current study demonstrated cost-effectiveness of CBT for adults who have self-harmed with the return-on-investment ratio of A$ 2.3 to $6.0 for every A$ 1 invested.

Aim Research is imperative to advance our understanding of suicidal behavior and its prevention. Suicide prevention research involves various ethical issues, many of which are not straightforward to address. Hence, suicide prevention researchers sometimes face particular issues when designing their research studies. This expert consensus study aimed to identify the most important ethical issues to consider when designing suicide prevention studies. Methods People with lived experience of suicide (N = 32) and suicide prevention researchers (N = 34) rated 80 statements on a 5-point Likert scale from "essential" to "should not be included." Results There was significant agreement between and within the two groups of participants with regard to the most highly rated statements. The most highly rated statements for both groups included the importance of the ethical principles of merit, integrity, justice, and beneficence. Additionally, lived experience participants placed emphasis on the support and care for researchers, and suicide prevention researchers placed emphasis on the risk management protocols and support services for participants. Conclusion There was strong agreement between people with lived experience of suicide and suicide prevention researchers regarding what to consider when designing ethically sound suicide prevention research, including the importance of ethical principles and support for both participants and researchers.

Background: National suicide prevention strategies support development of suicide prevention activities and their evaluation. Aims: To describe components included in national suicide prevention strategies and analyze the potential contribution of individual components to reduce suicide rates. Method: We conducted a narrative review and statistical analysis of national suicide prevention strategies. The narrative review was based on a framework of 12 components and included 29 countries (14 lower middle-income countries [LMICs] and 15 high-income countries [HICs]) with a national suicide prevention strategy. The statistical analyses covered suicide mortality data for 24 countries with a national strategy (9 LMICs and 15 HICs). Results: The number of components adopted in national strategies ranged from 4 to 11, and training and education were included in 96.5% of strategies. Estimated period effects for total suicide rates in individual countries ranged from a significant decrease in the yearly suicide rate (RR = 0.80; 95% CI 0.69-0.93) to a significant increase (RR = 1.12; 95% CI 1.05-1.19). There were no changes in suicide mortality associated with individual components of national strategies. Limitations: The limitations of existing suicide mortality data apply to our study. Conclusion: Further detailed evaluations will help identify the specific contribution of individual components to the impact national strategies. Until then, countries should be encouraged to implement and evaluate comprehensive national suicide prevention strategies.

Background Prior self-harm represents the most significant risk factor for future self-harm or suicide. Aim To evaluate the cost-effectiveness of a theoretical brief aftercare intervention (involving brief follow-up contact, care coordination and safety planning), following a hospital-treated self-harm episode, for reducing repeated self-harm within the Australian context. Method We employed economic modelling techniques to undertake: (a) a return-on-investment analysis, which compared the cost-savings generated by the intervention with the overall cost of implementing the intervention; and (b) a cost–utility analysis, which compared the net costs of the intervention with health outcomes measured in quality-adjusted life years (QALYs). We considered cost offsets associated with hospital admission for self-harm and the cost of suicide over a period of 10 years in the base case analysis. Uncertainty and one-way sensitivity analyses were also conducted. Results The brief aftercare intervention resulted in net cost-savings of AUD$7.5 M (95% uncertainty interval: −56.2 M to 15.1 M) and was associated with a gain of 222 (95% uncertainty interval: 45 to 563) QALYs over a 10-year period. The estimated return-on-investment ratio for the intervention's modelled cost in relation to cost-savings was 1.58 (95% uncertainty interval: −0.17 to 5.33). Eighty-seven per cent of uncertainty iterations showed that the intervention could be considered cost-effective, either through cost-savings or with an acceptable cost-effectiveness ratio of 50 000 per QALY gained. The results remained robust across sensitivity analyses. Conclusions A theoretical brief aftercare intervention is highly likely to be cost-effective for preventing suicide and self-harm among individuals with a history of self-harm.

AbstractIntroductionMedia guidelines for the responsible reporting of suicide are a recognized universal suicide prevention intervention. While implemented in numerous countries, including Australia, little is known about whether they are cost‐effective. We aimed to determine the cost‐effectiveness of Mindframe, the national initiative implementing media guidelines in Australia.MethodWe conducted a modelled economic evaluation (5‐year time‐horizon) incorporating two types of economic analysis: (i) return‐on‐investment (ROI) comparing estimated cost savings from the intervention to the total intervention cost, and (ii) cost‐effectiveness analysis comparing the net intervention costs to health outcomes: suicide deaths prevented and quality‐adjusted life‐years (QALYs). We also included uncertainty analyses to propagate parameter uncertainty and sensitivity analyses to test the robustness of the model outputs to changes in input parameters and assumptions.ResultsThe estimated ROI ratio for the main analysis was 94:1 (95% uncertainty interval [UI]: 37 to 170). The intervention was associated with cost savings of A$596M (95% UI: A$228M to A$1,081M), 139 (95% UI: 55 to 252) suicides prevented and 107 (95% UI: 42 to 192) QALYs gained. The intervention was dominant, or cost‐saving, compared with no intervention with results being robust to sensitivity analysis but varying based on the conservativeness of the parameters entered.ConclusionMindframe was found to be cost‐saving, and therefore, worthy of investment and inclusion as part of national suicide prevention strategies.

Background There is strong evidence that suicides increase after media stories about suicides by celebrities, particularly those that highlight the suicide method (the Werther effect). Much less is known about the Papageno effect-the protective effects of media stories of hope and recovery from suicidal crises. A synthesis of the retrievable evidence is lacking. We aim to summarise findings from randomised controlled trials about the effects of stories of hope and recovery on individuals with some degree of vulnerability to suicide. Methods For this systematic review and individual participant data meta-analysis, we searched PubMed (including MEDLINE), Scopus, Embase, PsycInfo, Web of Science, and Google Scholar published from inception to Sept 6, 2021, without language restrictions. We included trials that reported suicidal ideation (the primary outcome) or help seeking attitudes or intentions (the secondary outcome) and tested a media narrative of hope and recovery. Studies were excluded if they did not feature a clearly positive story of hope and recovery, or had a control group exposed to suicide-related stimulus material. We contacted the lead or senior authors of all original studies to obtain participant level data for this study. The primary analysis was restricted to individuals with some vulnerability to suicide. Risk of bias was assessed using the Cochrane risk-of-bias tool for randomised trials. The study is registered with PROSPERO, number CRD42020221341. Findings Our search yielded 7347 records. 3920 records were screened by title and abstract, and 25 full-text records assessed for eligibility. There were eight eligible studies with 2350 participants for which individual participant data were sought. For suicidal ideation, six studies met the inclusion criteria for the primary analysis. Follow-up responses were available for 569 (90%) of 633 participants who were randomised with high vulnerability (345 [55%] allocated to the intervention group and 288 [45%] to the control group). The pooled standardised mean difference (SMD) indicated a small reduction in suicidal ideation of -0.22 (95% CI -0.39 to -0.04, p=0.017; six studies) in the intervention group. For help-seeking attitudes and intentions, four studies met the inclusion criteria and follow-up data were available for 362 (86%) of 420 participants (247 [59%] allocated to the intervention group and 173 [41%] to the control group). The pooled SMD showed no evidence of a difference between the groups (SMD=0.14, 95% CI -0.15 to 0.43, p=0.35; four studies). Low levels of cross-study heterogeneity effects were observed for both analyses (I-2=5% [suicidal ideation] and I-2=36% [help-seeking attitudes and intentions]). We found no evidence of publication bias. Interpretation Media narratives of hope and recovery from suicidal crises appear to have a beneficial effect on suicidal ideation in individuals with some vulnerability, but there is insufficient evidence regarding help-seeking attitudes and intentions. These findings provide new evidence about narratives for suicide prevention. Copyright (C) 2022 The Author(s). Published by Elsevier Ltd.

Males in Australia and many other countries account for three-quarters of all deaths by suicide. School-based programs to support young men’s wellbeing have become increasingly common in recent years and show much promise to tackle the issue of male suicide by fostering protective factors and mitigating harmful factors. However, only a few of these programs have been evaluated. This trial seeks to address the lack of knowledge about the potential for school-based gender-transformative programs to have a positive impact on boys. Breaking the Man Code workshops, delivered by Tomorrow Man in Australia, challenge and transform harmful masculinities with young men with a view to ultimately reducing their suicide risk. The trial aims to examine whether adolescent boys who participate in the Breaking the Man Code workshop demonstrate an increase in their likelihood of seeking help for personal or emotional problems compared to boys waiting to take part in the workshop. A stratified cluster randomized controlled superiority trial with two parallel groups will be conducted. Schools will be randomly allocated 1:1, stratified by location of the schools (rural or urban), state (Victoria, NSW, or WA), and mode of workshop delivery (face-to-face or online), to the intervention group and waitlist control group. The Breaking the Man Code workshops show great promise as a school-based prevention intervention. The trial will fill a gap in knowledge that is critically needed to inform future interventions with boys and men. Some methodological challenges have been identified related to the COVID-19 pandemic in Australia, such as delays in ethics approvals and the need for Tomorrow Man to introduce an online delivery option for the workshop. The trial protocol has been designed to mitigate these challenges. The findings from the trial will be used to improve the workshops and will assist others who are designing and implementing suicide prevention interventions for boys and men.

Importance:Installation of barriers has been shown to reduce suicides. To our knowledge, no studies have evaluated the cost-effectiveness of installing barriers at multiple bridge and cliff sites where suicides are known to occur.Objective:To examine the cost-effectiveness of installing barriers at bridge and cliff sites throughout Australia.Design, Setting, and Participants:This economic evaluation used an economic model to examine the costs, costs saved, and reductions in suicides if barriers were installed across identified bridge and cliff sites over 5 and 10 years. Specific and accessible bridge and cliff sites across Australia that reported 2 or more suicides over a 5-year period were identified for analysis. A partial societal perspective (including intervention costs and monetary value associated with preventing suicide deaths) was adopted in the development of the model.Interventions:Barriers installed at bridge and cliff sites.Main Outcomes and Measures:Primary outcome was return on investment (ROI) comparing cost savings with intervention costs. Secondary outcomes included incremental cost-effectiveness ratio (ICER), comprising the difference in costs between installation of barriers and no installation of barriers divided by the difference in reduction of suicide cases. Uncertainty and sensitivity analyses were undertaken to examine the association of changes in suicide rates with barrier installation, adjustments to the value of statistical life, and changes in maintenance costs of barriers.Results:A total of 7 bridges and 19 cliff sites were included in the model. If barriers were installed at bridge sites, an estimated US $145 million (95% uncertainty interval [UI], $90 to $160 million) could be saved in prevented suicides over 5 years, and US $270 million (95% UI, $176 to $298 million) over 10 years. The estimated ROI ratio for building barriers over 10 years at bridges was 2.4 (95% UI, 1.5 to 2.7); the results for cliff sites were not significant (ROI, 2.0; 95% UI, -1.1 to 3.8). The ICER indicated monetary savings due to averted suicides over the intervention cost for bridges, although evidence for similar savings was not significant for cliffs. Results were robust in all sensitivity analyses except when the value of statistical life-year over 5 or 10 years only was used.Conclusions and Relevance:In an economic analysis, barriers were a cost-effective suicide prevention intervention at bridge sites. Further research is required for cliff sites.

Community coalitions have been recognised as an important vehicle to advance health promotion and address relevant local health issues in communities, yet little is known about their effectiveness in the field of suicide prevention. The Wesley Lifeforce Suicide Prevention Networks program consists of a national cohort of local community-led suicide prevention networks. This study drew on a nationally representative survey and the perspectives of coordinators of these networks to identify the key factors underpinning positive perceived network member and community outcomes. Survey data were analysed through descriptive statistics and linear regression analyses. Networks typically reported better outcomes for network members and communities if they had been in existence for longer, had a focus on the general community, and had conducted more network meetings and internal processes, as well as specific community-focused activities. Study findings strengthen the evidence base for effective network operations and lend further support to the merit of community coalitions in the field of suicide prevention, with implications for similar initiatives, policymakers, and wider sector stakeholders seeking to address suicide prevention issues at a local community level.

Background Strict adherence to masculine norms has been associated with deleterious consequences for the physical and mental health of men. However, population-based research is lacking, and it remains unclear whether ageing influences adherence to masculine norms and the extent to which mental health problems like depression are implicated. Methods This study reports on data from 14,516 males aged 15–55 years who participated in Wave 1 of the Australian Longitudinal Study of Male Health (Ten to Men). Group differences in self-reported conformity to masculine norms (CMNI-22), current depressive symptoms (PHQ-9), and self-reported 12-month depression history were examined for males aged 15–17 years, 18–25 years, 26–35 years, 36–50 years, and 51–55 years. Generalised linear models were used to examine the relationships between these variables across age groups. Results Conformity to masculine norms decreased significantly with age. However, models predicting depression generally showed that higher conformity to masculine norms was associated with an increased risk of current depressive symptoms, especially in the oldest age group. Conversely, higher conformity was associated with a decreased likelihood of a self-reported 12-month depression history, although nuances were present between age groups, such that this trend was not evident in the oldest age group. Conclusions Findings provide important insights into the complex relationship between conformity to masculine norms and depressive symptoms across the lifespan and further highlight the importance of mental health campaigns that address the complexities of gendered help-seeking behaviour for men.

Background Despite continuous research over the past 20 years in Australia there is still limited understanding of what works and what does not work in suicide prevention and where to invest research efforts that will help to expand this knowledge base. There is a recursive relationship between research activities, knowledge gain and the development of strategy and action plans as these in turn guide future decisions on research funding. In this context, the first step to continuous improvement in knowledge is to better understand where research has been invested in the past until now and where it has not. Methods We conducted a study that collected data over two periods. The first data collection was done in 2006 for the period of 1999 to 2006 and the second data collection was in 2017 for the period from 2010 to 2017. This allowed us to examine changes in published suicide-related journal articles, and grants/fellowships funded between the two periods. Published articles and grants/fellowships were classified according to a pre-determined framework. Results The number of suicide-related articles and grants/fellowships increased over the two periods. We noted shifts in the types of research that were funded and published, and in the emphasis that was given to different types of suicidal behavior, suicide methods, and settings. Research target groups showed a trend towards increasing diversification. Conclusions Our findings help to identify current research priorities and inform where future priorities for suicide-related research in Australia lie by linking findings to other external data sources (population risk data, stakeholder consultations, national strategies and action plan documents).

Background: The rate of suicide among men aged 85 years or older is the highest of any age or gender group in many countries, but little is known about their pathways to suicide. Aims: This study aimed to determine the context of suicide by men aged 85 years or older. Method: Data were extracted from the Victorian Suicide Register regarding suicide deaths between 2009 and 2015. Chi-squared test or Fisher's exact test was used to compare old men (65-84 years old) and older men (85 years or more), and old women and old men (both 65 years or more). Results: The context of suicide by older men differed significantly from that of old men, as did that of old men compared with old women, on variables related to suicidal behavior and intention, mental illness, mental health treatment, and life stressors. Limitations: The study is limited by the small numbers of deaths by suicide in this age group in Victoria. Conclusion: The context of suicide by older and old men is different from that of old men and old women, respectively. More research is needed to understand the pathways to suicide by older men.

Background Peer-led support models have gained increasing popularity in suicide prevention. While previous reviews show positive effects of peer-led support for people with mental health problems and those bereaved by suicide, little is known about the types of lived experience peer support programs in suicide prevention and whether these are effective in improving the health and wellbeing of people at risk of suicide. The aim of this paper is to provide an overview of peer support programs that aim to reduce suicidality and are led by people with lived experience of suicide. Method We conducted a systematic scoping review, involving a search of three academic (Medline, PsycINFO, Embase) and selected grey literature databases (Google Scholar, WHO Clinical Trials Registry) for publications between 2000 and 2019. We also contacted suicide prevention experts and relevant internet sites to identify peer support programs that exist but have not been evaluated. The screening of records followed a systematic two-stage process in alignment with PRISMA guidelines. Results We identified 8 records accounting for 7 programs focussed on peer-led support programs in suicide prevention. These programs employed a range of different designs and included a variety of settings (schools, communities, rural and online). Only 3 of the 7 programs contained data on effectiveness. With the small number of eligible programs the findings from this review are limited and must be interpreted with caution. Conclusions Despite the increased focus of policymakers on the importance of peer support programs in suicide prevention, our scoping review confirms an evidence gap in research knowledge regarding program design, implementation, and effectiveness. More rigour is required in reporting peer-led support initiatives to clarify the underlying definition of peer support and lived experience and to enhance our understanding of the types of current peer support programs available to those experiencing suicidality. Further, we need formal and high-quality evaluations of peer support suicide prevention programs led by people with lived experience to better understand their effectiveness on participant health across different settings and delivery modalities and to allow for comprehensive systematic reviews and meta-analysis in future.

Men aged 85 years and over have the highest rate of suicide of any age or gender group in Australia. However, little is known about their trajectory toward suicide. The objective of this study was to understand the role of masculine norms and other life factors in the suicidality of older men. Thirty-three men aged 80 years or more took part in a semistructured focus group or interview, and/or completed a survey. Participants were asked about the issues facing older men, well-being and aging, physical health challenges, social support, mental health and help-seeking, and suicide and suicide prevention. Five themes emerged: "finding out we're not invincible," "active and tough," "strong silent types," "decision makers," and "right to die." Participants spoke about masculine norms that had influenced their lives as providers and decision makers, and now influenced how they coped with aging and their journey toward death. For some participants, suicide was seen to be a rational alternative to dependence in their final years. Suicide prevention should adopt a gendered approach and be cognizant of the influence of gender roles and masculinity in older men's lives. Further research and prevention efforts should be mindful of the impact of masculine norms of self-reliance and control on an older man's decision to end his life. Suicide prevention efforts should work to reduce stigma around the challenges of aging, maximize opportunities for control, facilitate social connection, and improve residential aged care.
