Suicide prevention media campaigns are gaining traction as a means of combatting suicide. The current review set out to synthesize information about the effectiveness of these campaigns. We searched four electronic databases for studies that provided evidence on the effectiveness of media campaigns. We focused on studies that described an evaluation of the effectiveness of an entire campaign or a public service announcement explicitly aimed at suicide prevention. We identified 20 studies of varying quality. Studies that looked at whether campaign exposure leads to improved knowledge and awareness of suicide found support for this. Most studies that considered whether campaign materials can achieve improvements in attitudes toward suicide also found this to be the case, although there were some exceptions. Some studies found that media campaigns could boost help-seeking, whereas others suggested that they made no difference or only had an impact when particular sources of help or particular types of help-seeking were considered. Relatively few studies had sufficient statistical power to examine whether media campaigns had an impact on the ultimate behavioral outcome of suicides, but those that did demonstrated significant reductions. Our review indicates that media campaigns should be considered in the suite of interventions that might be used to prevent suicide. Evidence for their effectiveness is still amassing, but there are strong suggestions that they can achieve positive results in terms of certain suicide-related outcomes. Care should be taken to ensure that campaign developers get the messaging of campaigns right, and further work is needed to determine which messages work and which ones do not, and how effective messages should be disseminated. There is an onus on those developing and delivering campaigns to evaluate them carefully and to share the findings with others. There is a need for evaluations that employ rigorous designs assessing the most pertinent outcomes. These evaluations should explore the nature of given campaigns in detail – in particular the messaging contained within them – in order to tease out which messages work well and which do not. They should also take into account the reach of the campaign, in order to determine whether it would be reasonable to expect that they might have their desired effect.

Background: Debunking suicide myths, such as ‘asking someone about suicide could make them start thinking about it’ is a common strategy in suicide prevention education. However, there has been little research investigating the relationship between suicide myths and helping behavior toward people at risk of suicide. We aimed to identify sociodemographic characteristics associated with belief in eight common suicide myths and the associations between beliefs in these myths and helping intentions and behaviors toward a family member or friend in severe distress or at risk of suicide. Methods: We conducted a random digit dial (mobile and landline) survey of 3002 Australian adults. We asked respondents about their beliefs in suicide myths, intentions to help a person in severe distress or at risk of suicide presented in a vignette, and helping actions taken toward such a person in the last 12 months. We weighted this data to be representative of the Australian population. Regression analyses were undertaken to determine associations between sociodemographic and exposure characteristics and beliefs in suicide myths, and between beliefs in myths and helping intentions and behaviors. Results: Being male, speaking a language other than English at home and being over 60 years were associated with the strongest beliefs in suicide myths. The strongest and most consistent associations were found between belief in the myth ‘asking someone about suicide could make them start thinking about it’, risk assessment intentions and behaviours and intentions to undertaken actions not recommended for suicide prevention. Conclusions: Identifying those sociodemographic groups most likely to believe in suicide myths allows targeted intervention for suicide prevention education ‘debunking’ suicide myths. By isolating those myths that are most commonly believed, and their specific effects on helping intentions and behaviors, suicide prevention educators can target these specific myths to have the most effect on helping behavior. Our findings suggest that targeting the myth ‘asking someone about suicide could make them start thinking about it’ may have the greatest effects on helping behavior, and that men, those aged over 60 years and those speaking a language other than English at home could most benefit from myth ‘debunking’.

Improving access to culturally appropriate mental healthcare has been recognised as a key strategy to address the often greater burden of mental health issues experienced by Indigenous populations. We present data from the evaluation of a national attempt at improving access to culturally appropriate mental healthcare for Indigenous Australians through a mainstream primary mental healthcare program, the Access to Allied Psychological Services program, whilst specifically focusing on the implementation strategies and perspectives of service providers. We conducted semi-structured interviews with 31 service providers (primary care agency staff, referrers, and mental health professionals) that were analysed thematically and descriptively. Agency-level implementation strategies to enhance service access and cultural appropriateness included: the conduct of local service needs assessments; Indigenous stakeholder consultation and partnership development; establishment of clinical governance frameworks; workforce recruitment, clinical/cultural training and supervision; stakeholder and referrer education; and service co-location at Indigenous health organisations. Dedicated provider-level strategies to ensure the cultural appropriateness of services were primarily aimed at the context and process of delivery (involving, flexible referral pathways, suitable locations, adaptation of client engagement and service feedback processes) and, to a lesser extent, the nature and content of interventions (provision of culturally adapted therapy). This study offers insights into key factors underpinning the successful national service implementation approach. Study findings highlight that concerted national attempts to enhance mainstream primary mental healthcare for Indigenous people are critically dependent on effective local agency- and provider-level strategies to optimise the integration, adaptation and broader utility of these services within local Indigenous community and healthcare service contexts. Despite the explicit provider focus, this study was limited by a lack of Indigenous stakeholder perspectives. Key study findings are of direct relevance to inform the future implementation and delivery of culturally appropriate primary mental healthcare programs for Indigenous populations in Australia and internationally.

When a person is in severe distress, people in their social network can potentially take action to reduce the person’s suicide risk. The present study used data from a community survey to examine whether people who had received training in how to assist a person at risk of suicide had higher quality intentions and actions to provide support. A national telephone survey was carried out with 3002 Australian adults on attitudes and intentions toward helping someone in severe distress or at risk of suicide as well as actions taken. Participants were asked about their intentions to assist a hypothetical person in a vignette and about any actions they took to assist a family member or friend in distress over the previous 12 months. Participants were also asked whether they had received professional training, Mental Health First Aid training or other training in how to assist a person at risk of suicide. Responses covered ten intentions/actions that were recommended in guidelines for the public on how to support a suicidal person and 5 that were recommended against in the guidelines. Scales were created to measure positive and negative intentions to act and positive and negative actions taken. All three types of training were associated with greater positive intentions and actions, and with lesser negative intentions. These associations were largely due to a greater willingness of those trained to talk openly about suicide with a person in distress. Training in how to support a person at risk of suicide is associated with better quality of support. Such training merits wider dissemination in the community.

Much of our knowledge about the risk factors for suicide comes from case–control studies that either use a psychological autopsy approach or are nested within large register-based cohort studies. We would argue that case–control studies are appropriate in the context of a rare outcome like suicide, but there are issues with using this design. Some of these issues are common in psychological autopsy studies and relate to the selection of controls (e.g. selection bias caused by the use of controls who have died by other causes, rather than live controls) and the reliance on interviewing informants (e.g. recall bias caused by the loved ones of cases having thought about the events leading up to the suicide in considerable detail). Register-based studies can overcome some of these problems because they draw upon contain information that is routinely collected for administrative purposes and gathered in the same way for cases and controls. However, they face issues that mean that psychological autopsy studies will still sometimes be the study design of choice for investigating risk factors for suicide. Some countries, particularly low and middle income countries, don't have sophisticated population-based registers. Even where they do exist, there will be variable of interest that are not captured by them (e.g. acute stressful life events that may immediately precede a suicide death), or not captured in a comprehensive way (e.g. suicide attempts and mental illness that do not result in hospital admissions). Future studies of risk factors should be designed to progress knowledge in the field and overcome the problems with the existing studies, particularly those using a case–control design. The priority should be pinning down the risk factors that are amenable to modification or mitigation through interventions that can successfully be rolled out at scale.

Background: A suicide prevention media campaign aimed at family members and friends may be one useful population-level suicide prevention strategy for Australia. However, currently there is limited evidence of what messages would be acceptable and appropriate for inclusion. Aims: This expert consensus study aimed to identify messages that experts with lived experience of suicide risk and suicide prevention professionals believed were most important to include in such a suicide prevention campaign. Method: Using an online survey method, 127 participants with lived experience (lived experience group) and 33 suicide prevention professionals (suicide prevention professionals group) rated 55 statements, drawn from an earlier Delphi study, from very low priority to very high priority for inclusion in a suicide prevention campaign. Results: There was significant agreement within and between the two participant groups on the most highly rated messages for inclusion. The mostly highly rated messages were that family members or friends should ask directly about suicidal thoughts and intentions, listen to responses without judgment, and tell the person at risk that they care and want to help. Limitations: We restricted ratings to just one round and may therefore have limited the level of consensus achieved. Use of a predefined set of suicide prevention messages might also have prevented us from identifying other important messages. Lived experience participants were drawn from one source and this might bias their responses through exposure to common suicide prevention messages that influence their points of view. Conclusion: There is substantial agreement between professionals and people with lived experience on the most important messages to include in a suicide prevention campaign. These most highly rated messages could be adopted in a suicide prevention media campaign.
