Predictors of psychological improvement on non-professional suicide message boards: content analysis

CDC Guidance for Community Response to Suicide Clusters, United States, 2024

This is the third of three reports in the MMWR supplement that updates and expands CDC's guidance for assessing, investigating, and responding to suicide clusters based on current science and public health practice. The first report, Background and Rationale - CDC Guidance for Communities Assessing, Investigating, and Responding to Suicide Clusters, United States, 2024, describes an overview of suicide clusters, methods used to develop the supplement guidance, and intended use of the supplement reports. The second report, CDC Guidance for Community Assessment and Investigation of Suspected Suicide Clusters, United States, 2024, describes the potential methods, data sources, and analysis that communities can use to identify and confirm suspected suicide clusters and better understand the relevant issues. This report describes how local public health and community leaders can develop a response plan for suicide clusters. Specifically, the steps for responding to a suicide cluster include preparation, direct response, and action for prevention. These steps are not intended to be explicitly adopted but rather adapted into the local context, culture, capacity, circumstances, and needs for each suicide cluster.

Experiences of suicide survivors of sharing their stories about suicidality and overcoming a crisis in media and public talks: a qualitative study

BACKGROUND

Media stories of hope and recovery from suicidal ideation have been found to have a positive impact on the audience, but little is known about how individuals who share their own experiences perceive the effects of their storytelling. This study aimed to assess qualitatively, through focus groups, how individuals who shared their personal story of hope and recovery in the media and public talks experienced the process, and which aspects they perceived as important in sharing their coping story.

METHODS

Three focus groups were conducted with a total of n = 12 individuals. These included n = 5 participants with experience of suicidal ideation or a suicide attempt, n = 4 individuals who had been bereaved through suicide, and n = 3 participants who experienced both. Participants were recruited from the American organisation "Suicide Survivors United". Thematic analysis was used to assess the participants' perception and experiences of sharing their story.

RESULTS

Participants shared that the intention to help others was the main motivation to share their story of hope and recovery. Participants noted many positive effects of their storytelling on themselves and also received positive feedback from the audience, such as improved help-seeking attitudes. The participants offered recommendations for those who want to share their story of hope and recovery, including careful personal preparation and media training before going public. They also discussed media recommendations for talking about suicide in the media.

CONCLUSIONS

Sharing a personal story of hope and recovery may have a beneficial impact on the storytellers. Storytelling requires a careful preparation and training before going public and support and guidance is crucial in all stages of the storytelling, particularly to help unexperienced storytellers in going public and using their personal narratives to help prevent suicide.

Self-harm and suicidal content online, harmful or helpful? A systematic review of the recent evidence

Purpose

There are calls for greater regulation of online content related to self-harm and suicide, particularly that which is user-generated. However, the online space is a source of support and advice, including an important sharing of experiences. This study aims to explore what it is about such online content, and how people interact with it, that may confer harm or offer benefit.

Design/methodology/approach

The authors undertook a systematic review of the published evidence, using customised searches up to February 2021 in seven databases. The authors included empirical research on the internet or online use and self-harm or suicide content that had been indexed since 2015. The authors undertook a theoretically driven narrative synthesis.

Findings

From 4,493 unique records, 87 met our inclusion criteria. The literature is rapidly expanding and not all the evidence is high quality, with very few longitudinal or intervention studies so little evidence to understand possible causal links. Very little content online is classifiable as explicitly harmful or definitively helpful, with responses varying by the individual and immediate context. The authors present a framework that seeks to represent the interplay in online use between the person, the medium, the content and the outcome.

Originality/value

This review highlights that content should not be considered separately to the person accessing it, so online safety means thinking about all users. Blanket removal or unthinking regulation may be more harmful than helpful. A focus on safe browsing is important and tools that limit time and diversify content would support this.

Self-disclosure in public and private groups of people with mental illnesses in Facebook

Purpose

The Internet enables various voices and opinions that previously did not participate in the community discourse to express themselves. People with mental illnesses make use of social networks to advance their special needs in varied ways. The study aims to examine the nature of the discourse that takes place in public and private groups of people with mental illnesses.

Design/methodology/approach

The research corpus consisted of the content of 615 messages taken from public and private groups of people with mental illnesses in Facebook. Linguistic parameters (the total number of words, the number of words in the first person) were examined for each message. Two skilled judges classified the messages on a self-disclosure scale to determine the degree of disclosure of personal information, thoughts and emotions.

Findings

The results of the study indicate that the messages published in public groups are longer than the messages in private groups; however, the level of personal disclosure in messages written in private groups is deeper than in messages written in public groups. In addition, the level of self-disclosure in opening posts was found to be greater than the level of self-disclosure in comments.

Practical implications

In the study, the authors focus on the ways people in excluded populations make use of virtual tools to advance both their personal and social needs.

Originality/value

The study is innovative, as it explores the discourse of people with mental illnesses in public and private groups on Facebook.

Peer-based interventions targeting suicide prevention: A scoping review

Peers of individuals at risk for suicide may be able to play important roles in suicide prevention. The aim of the current study is to conduct a scoping review to characterize the breadth of peer-delivered suicide prevention services and their outcomes to inform future service delivery and research. Articles were selected based on search terms related to peers, suicide, or crisis. After reviews of identified abstracts (N = 2681), selected full-text articles (N = 286), and additional references (N = 62), a total of 84 articles were retained for the final review sample. Types of suicide prevention services delivered by peers included being a gatekeeper, on-demand crisis support, crisis support in acute care settings, and crisis or relapse prevention. Peer relationships employed in suicide prevention services included fellow laypersons; members of the same sociodemographic subgroup (e.g., racial minority), workplace, or institution (e.g., university, correctional facility); and the shared experience of having a mental condition. The majority of published studies were program descriptions or uncontrolled trials, with only three of 84 articles qualifying as randomized controlled trials. Despite a lack of methodological rigor in identified studies, peer support interventions for suicide prevention have been implemented utilizing a diverse range of peer provider types and functions. New and existing peer-delivered suicide prevention services should incorporate more rigorous evaluation methods regarding acceptability and effectiveness.

Suicide Exposure in a Polymediated Age

With growing evidence that media plays a vital role in shaping public understanding of suicidality and influencing behaviours, media portrayals of suicidality have for some time been the focus of suicide prevention efforts. Traditional media has changed, and now exists alongside and within an instantaneous, interactive sharing of information created and controlled by anyone; the way most people use it today incorporates a wide variety of online communication media. Polymedia describes media communication as both a product and process, where anyone can contribute and act as producers, consumers, audiences, and critics. In a “Polymediated age,” media exposure becomes much more complex. To understand how media exposure to suicide influences and impacts on others, it is important to take into account the communicative ecology of media technologies and the different interactions we can have with them. We researched the effects of this type of exposure by conducting in-depth interviews with a purposive sample of individuals who have lived experience and/or knowledge of suicide exposure via polymediated communication in the aftermath of a suicide. Using thematic analysis, our data demonstrates how exposure to suicide has become more complex as a result of new communicative media technology: it can be both a gift and a curse, difficult to distinguish, predict or control. Polymedia has the power to determine new forms of narrative and new forms of behaviour that on the one hand can provide support and prevention efforts, while on the other hand can promote conflict and cast an adverse influence on suicidal behaviour. Polymedia provides novel affordances for very intimate collective exposure to suicide. Our findings shed important new light on how the interplay between news media and social media has transformed our relationship with the information to which we’re exposed. We highlight important suggestions for those working in suicide prevention to develop (1) media strategies that recognise the multiple ways in which users are exposed and impacted, and (2) mechanisms for a strategic amplification and moderation of specific types of content. Media organisations and users of social media alike can contribute to maximising the beneficial capacity of polymediated exposure to suicide.

Time-series analyses of firearm-related Google searches and U.S. suicide rates 2004-2016

OBJECTIVE

The U.S. suicide rate has increased 35% since 1999. The role of the Internet has not been thoroughly investigated despite Internet use more than doubling from 1999 to present. The majority of U.S. suicide deaths are by firearm; however, there is no examination of the association between trends in firearm Internet searches and overall and firearm monthly suicide rates. We hypothesized that search strings related to firearm suicide would be significantly associated with monthly suicide rates (both all methods and firearm).

METHODS

Google Trends provides data on request frequencies of searches. Twenty-four search strings were examined representing possible searches by individuals considering firearm suicide and compared to U.S. suicide rates with time-series modeling.

RESULTS

In the time series with higher search volumes, consistent associations were found of negative cross-correlation at lag +1.

CONCLUSIONS

Several searches appeared at least sensitive enough to consistently show associations with overall and firearm suicide rates in the following month. This novel finding should be followed up as the potential exists to predict suicide trends.

Lived experience peer support programs for suicide prevention: a systematic scoping review

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.

Communication about suicide in YouTube videos: Content analysis of German-language videos retrieved with method-and help-related search terms

Online searches for information on suicide are very common but studies on how the topic is addressed on one of the the most relevant platforms, YouTube, are missing. We performed a content analysis of German-language videos retrieved with the basic term "suicide", a method-related search term ("how to hang yourself"), and a help-related term ("suicide prevention"). We assessed the quality of n=232 randomly selected videos based on media recommendations for suicide reporting. Characteristics of videos retrieved with the method- and help-related search term, were compared to search results for "suicide". Videos retrieved with the help-related term had more potentially protective and fewer harmful characteristics than those retrieved with the other search terms. For example, these videos significantly more often debunked suicide myths and provided contact information to help services. In total, the mean number of harmful and protective characteristics per video were 1.6 and 1.3 for basic searches; 1.7 and 1.0 for method-related searches, and 0.4 and 2.8 for help-related searches, respectively. Videos retrieved in the help-related search were often from help organizations. Only 3% and 8% of videos retrieved with "suicide" and "how to hang yourself", respectively, were age-restricted. Collaborations between suicide prevention and Youtube are warranted to improve the visibility of protective contents and ensure a better implementation of Youtube's own policies regarding self-harm.

The Relationship Between Suicide-Related Twitter Events and Suicides in Ontario From 2015 to 2016

Background: Many studies have demonstrated suicide contagion through mainstream journalism; however, few have explored suicide-related social media events and their potential relationship to suicide deaths. Aims: To determine whether Twitter events were associated with changes in subsequent suicides. Methods: Suicide-related Twitter events that garnered at least 100 tweets originating in Ontario, Canada (July 1, 2015 to June 30, 2016) were identified and characterized as putatively "harmful" or "innocuous" based on recommendations for responsible media reporting. The number of suicides in Ontario during the peak of each Twitter event and the subsequent 6 days ("exposure window") was compared with suicides occurring during a pre-event period of the same length ("control window"). Results: There were 17 suicide-related Twitter events during the period of study (12 putatively harmful and five putatively innocuous). The number of tweets per event ranged from 121 for "physician-assisted suicide law in Quebec" to 6,202 for the "Attawapiskat suicide crisis." No significant relationship was detected between Twitter events and actual suicides. Notably, a comprehensive examination of the details of Twitter events showed that even the putatively harmful events lacked many of the characteristics commonly associated with contagion. Limitations: This was an uncontrolled experiment in only one epoch and a single Canadian province. Discussion: This study found no evidence of suicide contagion associated with Twitter events. This finding must be interpreted with caution given the relatively innocuous content of suicide-related Tweets in Ontario during 2015-2016.

A systematic literature review of machine learning in online personal health data

OBJECTIVE

User-generated content (UGC) in online environments provides opportunities to learn an individual's health status outside of clinical settings. However, the nature of UGC brings challenges in both data collecting and processing. The purpose of this study is to systematically review the effectiveness of applying machine learning (ML) methodologies to UGC for personal health investigations.

MATERIALS AND METHODS

We searched PubMed, Web of Science, IEEE Library, ACM library, AAAI library, and the ACL anthology. We focused on research articles that were published in English and in peer-reviewed journals or conference proceedings between 2010 and 2018. Publications that applied ML to UGC with a focus on personal health were identified for further systematic review.

RESULTS

We identified 103 eligible studies which we summarized with respect to 5 research categories, 3 data collection strategies, 3 gold standard dataset creation methods, and 4 types of features applied in ML models. Popular off-the-shelf ML models were logistic regression (n = 22), support vector machines (n = 18), naive Bayes (n = 17), ensemble learning (n = 12), and deep learning (n = 11). The most investigated problems were mental health (n = 39) and cancer (n = 15). Common health-related aspects extracted from UGC were treatment experience, sentiments and emotions, coping strategies, and social support.

CONCLUSIONS

The systematic review indicated that ML can be effectively applied to UGC in facilitating the description and inference of personal health. Future research needs to focus on mitigating bias introduced when building study cohorts, creating features from free text, improving clinical creditability of UGC, and model interpretability.

Mining social networks to improve suicide prevention: A scoping review

Attention about the risks of online social networks (SNs) has been called upon reports describing their use to express emotional distress and suicidal ideation or plans. On the Internet, cyberbullying, suicide pacts, Internet addiction, and "extreme" communities seem to increase suicidal behavior (SB). In this study, the scientific literature about SBs and SNs was narratively reviewed. Some authors focus on detecting at-risk populations through data mining, identification of risks factors, and web activity patterns. Others describe prevention practices on the Internet, such as websites, screening, and applications. Targeted interventions through SNs are also contemplated when suicidal ideation is present. Multiple predictive models should be defined, implemented, tested, and combined in order to deal with the risk of SB through an effective decision support system. This endeavor might require a reorganization of care for SNs users presenting suicidal ideation.

Types of Stressors on Nonprofessional Against-Suicide and Pro-Suicide Message Boards

Background: Little is known about presenting problems of primary posters (i.e., posters opening the thread) and their responders in nonprofessional against-suicide and pro-suicide message boards. Aims: We aimed to compare problems described in suicide message boards between different types of users (primary posters and respondents) and between against-suicide, neutral, and pro-suicide message boards. Method: In all, 1,182 archival threads with 20,499 individual postings from seven nonprofessional suicide message boards supporting an against-suicide, neutral, or pro-suicide attitude were randomly selected. Problems mentioned by primary posters and their respondents were coded with content analysis. Differences between pro-suicide, neutral, and against suicide boards, as well as correlations between primary posters and respondents, were calculated. Results: Interpersonal problems were most frequently mentioned by primary posters in against-suicide threads (40.9%) and less frequently in pro-suicide threads (11.8%; p < .001). In pro-suicide boards, the most frequent stressors were suicide method-related (e.g., how to identify a safe method: 26.2% vs. 2.5% in against-suicide boards, p < .001). Primary posters resembled respondents in terms of presenting problems in pro-suicide boards, but not in against-suicide boards. Limitations: Only self-reported problems were assessed. Conclusion: The results confirm a stronger focus on death than on life among users in pro-suicide message boards, and posters with similar problems meet in pro-suicide boards. The posters appear to clearly emphasize social strains over psychiatric problems compared with some professional settings.

Theoretical and empirical foundations of a novel online social networking intervention for youth suicide prevention: A conceptual review

Suicide is a major public health problem and is the second leading cause of death in young people worldwide. Indicating a lack of adequate treatment approaches, recent data suggest a rising suicide rate. Current approaches to suicide prevention do not sufficiently account for the specific needs of young people or the ways in which they engage with the health system, nor are they adequately theory-driven. In this paper, we review an empirically-supported theoretical model of suicide together with the latest evidence in treating young people who are at risk. We discuss the potential efficacy of social-media-based online interventions, with a particular focus on how they may be uniquely placed to target interpersonal risk factors for suicide. We highlight the risks associated with such interventions, including the potential for contagion to occur. Based on prominent theoretical models and gaps in existing treatment approaches, we propose a newly-developed, theory-driven, online social-networking-based intervention for suicide prevention in young people.

The rate of reply and nature of responses to suicide-related posts on Twitter

The social media platform Twitter has been used by individuals to communicate suicidal thoughts and intentions. Currently, the nature and rate of reply to this type of Twitter content is unknown. This brief report aimed to understand how Twitter users respond to suicide-related content as compared to non-suicide related content. Using a dataset of suicide and non-suicide related posts, replies, retweets and likes were analysed and compared. The content of the first replies to suicide-related posts were also reviewed. When compared to non-suicide related posts, those that were suicide-related received a significantly greater number of replies, with fewer retweets and likes. The rate of reply to the suicide-related posts was also significantly faster than that of the non-suicide related posts, with the average reply occurring within 1 h. Thematic analysis revealed that 62% of the first replies to suicidal posts were of a potentially helpful nature (e.g. discouraging suicide, caring, or clarifying), while 23% were dismissive or encouraging of the suicide. These findings indicate that Twitter users respond differently to suicidal content. Further research is needed to determine the effects of the replies on suicidal intentions or ideations, and whether this platform can be used to intervene, increase help-seeking, or provide anti-stigma campaigns.

Comparing Indicators of Suicidality Among Users in Different Types of Nonprofessional Suicide Message Boards

BACKGROUND

Little is known about linguistic differences between nonprofessional suicide message boards that differ in regard to their predominant attitude to suicide.

AIMS

To compare linguistic indicators potentially related to suicidality between anti-suicide, neutral, and pro-suicide message boards, and between the types of posters (primary posters, who initiate the thread, and the respective respondents).

METHOD

In all, 1,200 threads from seven German-language nonprofessional suicide message boards were analyzed using the software Linguistic Inquiry and Word Count (LIWC) with regard to wording related to suicidal fantasies, aggression, and indicators of so-called suicidal constriction. Data were analyzed with ANOVA.

RESULTS

There were fewer words related to affective, social, cognitive, and communicative processes in pro-suicide message boards than in other boards. Death-related wording and aggression as well as tentative wording appeared more prevalent in pro-suicide boards.

LIMITATIONS

Complex language structures cannot be analyzed with LIWC.

CONCLUSION

The results suggest fewer emotion words and wording related to social circumstances among primary posters and respondents in pro-suicide boards as compared with other boards, and a higher use of death- and aggression-related words. These findings might signal a higher degree of suicidality or sheer differences in matters of interest or social desirability. The differences require attention in practice and research.
