Background: Prior work has explored the impact of follow-up calls in a crisis line context, but no research has investigated the offer and acceptance of follow-up care. Aims: To identify caller/call characteristics associated with whether a caller is offered and accepts follow-up services. Methods: This cross-sectional study included data from 55,594 callers to a member center of the 988 Suicide & Crisis Lifeline (988) between 2017 and 2019. Logistic regression analyses were conducted to examine associations between caller/call characteristics and two follow-up outcomes. Results: Black callers and those with higher suicide capability and intent had greater odds of being offered and accepting follow-up. Longer call duration was also associated with higher odds of being offered and accepting follow-up. Higher suicidal desire uniquely increased the odds of offers, whereas a higher level of buffers uniquely decreased the odds of offers. Limitations: Data were collected from a single 988-member center and cannot be generalized. Conclusions: That one-third of callers do not accept follow-up highlights the need to understand reasons for not accepting follow-up. That callers with higher risk profiles are offered and accept follow-up at higher rates is reassuring and underscores the benefit of tailoring follow-up interventions for higher-risk callers.

UNASSIGNED: This study aimed to examine mortality for people living with dementia/mild cognitive impairment who self-harmed.
UNASSIGNED: We conducted a retrospective cohort study in New South Wales, Australia, using data ranging from 2001 to 2015. From people who accessed hospital services in the study period, we identified 154,811 people living with dementia/mild cognitive impairment, 28,972 who self-harmed and 1511 who had a record of both dementia/mild cognitive impairment and self-harm. We examined rates, causes and predictors of death for people with dementia/mild cognitive impairment and/or self-harm diagnoses using flexible parametric survival analyses. We explored rates of repeat self-harm in people living with dementia who self-harmed.
UNASSIGNED: Circulatory disorders accounted for 32.0% of deaths in people with a living with dementia who self-harmed, followed by neoplasms (14.7%), and mental and behavioural disorders (9.6%). Death was more likely for someone who had self-harmed if they developed dementia/mild cognitive impairment. Predictors of death included male sex, greater physical comorbidity, a history of delirium, more previous emergency department presentations and fewer previous mental health ambulatory service days. Greater engagement with outpatient mental health services predicted a decreased likelihood of repeat self-harm.
UNASSIGNED: We found that mortality increases when people who self-harm develop dementia. We argue post-diagnosis support offers a potential opportunity to reduce mortality rates in people with both dementia and self-harm diagnoses.

Despite an alarming rise in firearm suicide rates within Black communities, there has been little research on the contributors that precede firearm suicide deaths among Black adults. To fill this knowledge gap, this study was guided by an overarching research question: What are the recurring and salient personal circumstances experienced by Black adults prior to dying by firearm suicide in the US? This basic, interpretive qualitative study analyzed narrative text data for 843 Black adult firearm suicide decedents from the National Violent Death Reporting System. The analysis began with an initial cycle of open coding, followed by a second coding cycle, organizing the circumstances into major categories using a focused coding process. The analysis then moved back and forth between description and interpretation, and major themes were developed. Five themes emerged from this analysis: (1) Decedents often experienced poor health prior to death - but not always poor mental health. (2) Romantic relationships were often deteriorating, leading to frequent interpersonal arguments. (3) Alcohol and substance use were common before a suicide attempt. (4) Decedents frequently experienced financial and legal difficulties prior to death. (5) Decedents had many pathways to accessing firearms, and limiting firearm availability before death was challenging. Additional research on potential intervention pathways will be critical, given recent evidence indicating dramatic increases in firearm ownership among Black adults over the past 5 years.

Some have challenged the validity of labelling suicidal thoughts and behaviours (STB) as pathological. In this paper, we argue that STB is indeed pathological, thereby, situating suicide prevention within the realm of medicine, complicating calls for the legalisation of medical assistance in dying for individuals whose sole condition is psychiatric (psychiatric medical assistance in dying (MAID)). Evidence shows STB predicts the risk of suicide; moreover, several mental illnesses are associated with STB, and 70%-90% of suicide deaths are linked to psychiatric illness. Treating psychiatric illnesses can prevent suicide. We contend that this clinical evidence not only warrants the classification of STB as pathological but also necessitates its treatment and prevention. This perspective poses a challenge to legislation that would legalise psychiatric MAID.

As rates of adolescent hospitalization for suicide-related crises increase, so does the urgency for improving adolescent school reintegration. Communication and collaboration are considered key mechanisms for continuity of care during times of transition; however, to date, few studies have identified critical information to share or have explored strategies for navigating challenges to information sharing during and following school reintegration. The present study explored previously hospitalized adolescent (n = 19), parent (n = 19), school professional (n = 19), and hospital professional (n = 19) views of information sharing and their perceptions of facilitators and barriers to this communication. Applied thematic analysis revealed three key themes related to the best information to share across entities, including the (a) need to consider environmental relevance to information (i.e., informing school supports and hospital treatment), (b) importance of considering information unique to each patient\'s circumstance (i.e., sharing information on a \"case-by-case basis\"), and (c) duality between families preferring to share minimal information but school professionals desiring the maximum (i.e., less is more vs. more is better). Regarding facilitators and barriers to information sharing, six key themes emerged, including (a) understanding risks and benefits of information sharing; (b) trust in hospitals and schools; (c) mental health stigma; (d) communication processes; (e) navigating individual, family, school, and community contexts; and (f) \"push and pull\" between privacy and need. Findings inform key considerations for collaborating with families in determining if and what information to share during school reintegration.

BACKGROUND: Differences in social and environmental factors contribute to disparities in fatal injury rates. This study assessed the relationship between social vulnerability and homicide and suicide rates across United States counties.
METHODS: County-level age-adjusted homicide and suicide rates for 2016-2020 were linked with data from the Centers for Disease Control and Prevention\'s 2020 Social Vulnerability Index (SVI), a dataset identifying socially vulnerable communities. We conducted negative binomial regressions to examine the association between SVI and homicide and suicide rates, overall and by Census region/division. We mapped county-level data for SVI and homicide and suicide rates in bivariate choropleth maps.
RESULTS: Overall SVI was associated with homicide rates across U.S. counties. While no association was found for overall SVI and suicide rates, Socioeconomic Status and Racial & Ethnic Minority Status domains were associated. The geographic distribution of SVI and homicide and suicide rates varied spatially; notably, counties in the South had the greatest levels of social vulnerability and greatest homicide rates.
CONCLUSIONS: Our findings demonstrate county-level social vulnerability is associated with homicide rates but may be more nuanced for suicide rates. A modified SVI for injury should include additional social and structural determinants and exclude variables not applicable to injuries.
CONCLUSIONS: This study combines the SVI with homicide and suicide data, enabling researchers to examine related social and environmental factors. Modifying the SVI to include relevant predictors could improve injury prevention strategies by prioritizing efforts in areas with high social vulnerability.

OBJECTIVE: Suicide prevention strategies have shifted in many countries, from a national approach to one that is regionally tailored and responsive to local community needs. Previous Australian studies support this approach. However, most studies have focused on suicide deaths which may not fully capture a complete understanding of prevention needs, and few have focused on the priority population of youth. This was the first nationwide study to examine regional variability of self-harm prevalence and related factors in Australian young people.
METHODS: A random sample of Australian adolescents (12-17-year-olds) were recruited as part of the Young Minds Matter (YMM) survey. Participants completed self-report questions on self-harm (i.e., non-suicidal self-harm and suicide attempts) in the previous 12 months. Using mixed effects regressions, an area-level model was built with YMM and Census data to produce out-of-sample small area predictions for self-harm prevalence. Spatial unit of analysis was Statistical Area Level 1 (average population 400 people), and all prevalence estimates were updated to 2019.
RESULTS: Across Australia, there was large variability in youth self-harm prevalence estimates. Northern Territory, Western Australia, and South Australia had the highest estimated state prevalence. Psychological distress and depression were factors which best predicted self-harm at an individual level. At an area-level, the strongest predictor was a high percentage of single unemployed parents, while being in an area where ≥30% of parents were born overseas was associated with reduced odds of self-harm.
CONCLUSIONS: This study identified characteristics of regions with lower and higher youth self-harm risk. These findings should assist governments and communities with developing and implementing regionally appropriate youth suicide prevention interventions and initiatives.

UNASSIGNED: Suicide rates have been increasing in Australia since the mid-2000s, especially for women aged ≤25 years. We conducted an age-period-cohort study to investigate these recent trends in the context of historical Australian suicide rates.
UNASSIGNED: Data on annual suicides in Australia from 1907 to 2020 were extracted from the General Record of Incidence of Mortality. We modelled age-specific effects for a reference cohort, after adjustment for period effects.
UNASSIGNED: We found evidence of age, cohort and period effects. For males, compared to the cohort born in 1946-1950, rates were higher for all cohorts born after this year. The period effect showed peaks in the risk of male suicide in the mid 1960s and the early 1990s, followed by a decline in risk until early 2010, after which the risk began to rise again. For females, compared to the cohort born in 1946-1950, the risk of suicide was higher for all cohorts born after this, with the highest risk for those born in 2006-2010. The period effect for females showed an elevated risk of suicide in the mid 1960s followed by a sharp decline, and an increase in risk after 2009.
UNASSIGNED: Suicide rates in Australia have fluctuated substantially over time and appear to be related to age trends as well as period and cohort trends. Advocacy and policy making tends to focus on contemporaneous changes in suicide rates. However, this study shows that focusing only on year-on-year changes in suicide rates ignores underlying trends for specific population birth-cohorts.
UNASSIGNED: None.

BACKGROUND: Military Servicemembers and Veterans are at elevated risk for suicide, but rarely self-identify to their leaders or clinicians regarding their experience of suicidal thoughts. We developed an algorithm to identify posts containing suicide-related content on a military-specific social media platform.
METHODS: Publicly-shared social media posts (n = 8449) from a military-specific social media platform were reviewed and labeled by our team for the presence/absence of suicidal thoughts and behaviors and used to train several machine learning models to identify such posts.
RESULTS: The best performing model was a deep learning (RoBERTa) model that incorporated post text and metadata and detected the presence of suicidal posts with relatively high sensitivity (0.85), specificity (0.96), precision (0.64), F1 score (0.73), and an area under the precision-recall curve of 0.84. Compared to non-suicidal posts, suicidal posts were more likely to contain explicit mentions of suicide, descriptions of risk factors (e.g. depression, PTSD) and help-seeking, and first-person singular pronouns.
CONCLUSIONS: Our results demonstrate the feasibility and potential promise of using social media posts to identify at-risk Servicemembers and Veterans. Future work will use this approach to deliver targeted interventions to social media users at risk for suicide.
