Abstract
Firearms account for approximately half of all suicide deaths within the United States each year. Recently, Lane and Kleck published pieces reporting conflicting results regarding the relationship between firearm access and suicide rates. In this commentary, I aim to contextualize the findings within the broader literature and to provide clarity for readers aiming to navigate the findings of the two studies. Ultimately, I conclude that the results of Lane more accurately represent the nature of the relationship and align with the extant literature on the topic.

Abstract
INTRODUCTION Suicide remains a leading cause of death in the U.S., and firearms are one of the most lethal methods of suicide. This study examines personal and contextual factors that predict suicide with a firearm compared to other methods across stages of adulthood. METHODS Data on adult suicide decedents from 2009 to 2019 were obtained from Colorado's National Violent Death Reporting System (NVDRS) data (N = 11,512). The dataset includes incident and person characteristics collected by law enforcement and coroners. Zip code level data were integrated from the American Community Survey. RESULTS Age, sex, race, marital status, military service, substance use, suicide attempt history, mental health, and location characteristics (population density, as well as age, education, veteran status, and household status of population) predicted suicide by firearm. Risk was particularly high for males in older adulthood. We further explored age-specific models (young, middle-aged, and older adults) to determine salient risk factors for each group. CONCLUSION This study highlights the need for comprehensive suicide prevention approaches that consider both individual and contextual risk factors, as well as unique risks in each stage of adulthood.

Abstract
PURPOSE Insomnia is a modifiable risk factor for suicide often treated with medications. However, little is known about the associations between insomnia medications and risk of death by suicide. The purpose of this study is to model the comparative risk of suicide by each insomnia medication compared to zolpidem, a sedative-hypnotic approved for insomnia. METHODS First prescription fills of medications commonly used to treat insomnia were identified in electronic medical records. Date and cause of death were identified in death certificates. Cox proportional hazards models were used to analyze time from insomnia prescription to suicide. RESULTS More than 2 million patients filled a new insomnia prescription between 2005 and 2015, and 518 of them died by suicide within 12 months. Compared to zolpidem, the tricyclic antidepressants (amitriptyline, doxepin) were associated with a 64% lower risk of suicide (HR 0.36 (95% CI 0.22-0.66) and the sedating antihistamines (hydroxyzine, diphenhydramine) a 40% lower risk of suicide (HR 0.60 (0.41-0.89)). In contrast, the tetracyclic antidepressant (mirtazapine) was associated with a 62% higher risk of suicide (HR 1.62 (95% CI 1.10-2.38) compared to zolpidem. CONCLUSION Insomnia is a modifiable risk factor for suicide, yet many medications used to treat insomnia have never been tested for the indication in clinical trials. To define efficacy in the prevention of suicide, trials are warranted.

Abstract
BACKGROUND Firearm suicide has been more prevalent among males, but age-adjusted female firearm suicide rates increased by 20% from 2010 to 2020, outpacing the rate increase among males by about 8 percentage points, and female firearm suicide may have different contributing circumstances. In the United States, the National Violent Death Reporting System (NVDRS) is a comprehensive source of data on violent deaths and includes unstructured incident narrative reports from coroners or medical examiners and law enforcement. Conventional natural language processing approaches have been used to identify common circumstances preceding female firearm suicide deaths but failed to identify rarer circumstances due to insufficient training data. OBJECTIVE This study aimed to leverage a large language model approach to identify infrequent circumstances preceding female firearm suicide in the unstructured coroners or medical examiners and law enforcement narrative reports available in the NVDRS. METHODS We used the narrative reports of 1462 female firearm suicide decedents in the NVDRS from 2014 to 2018. The reports were written in English. We coded 9 infrequent circumstances preceding female firearm suicides. We experimented with predicting those circumstances by leveraging a large language model approach in a yes/no question-answer format. We measured the prediction accuracy with F1-score (ranging from 0 to 1). F1-score is the harmonic mean of precision (positive predictive value) and recall (true positive rate or sensitivity). RESULTS Our large language model outperformed a conventional support vector machine-supervised machine learning approach by a wide margin. Compared to the support vector machine model, which had F1-scores less than 0.2 for most infrequent circumstances, our large language model approach achieved an F1-score of over 0.6 for 4 circumstances and 0.8 for 2 circumstances. CONCLUSIONS The use of a large language model approach shows promise. Researchers interested in using natural language processing to identify infrequent circumstances in narrative report data may benefit from large language models.

Abstract
INTRODUCTION Since 2005, female firearm suicide rates increased by 34%, outpacing the rise in male firearm suicide rates over the same period. The objective of this study was to develop and evaluate a natural language processing pipeline to identify a select set of common and important circumstances preceding female firearm suicide from coroner/medical examiner and law enforcement narratives. METHODS Unstructured information from coroner/medical examiner and law enforcement narratives were manually coded for 1,462 randomly selected cases from the National Violent Death Reporting System. Decedents were included from 40 states and Puerto Rico from 2014 to 2018. Naive Bayes, Random Forest, Support Vector Machine, and Gradient Boosting classifier models were tuned using 5-fold cross-validation. Model performance was assessed using sensitivity, specificity, positive predictive value, F1, and other metrics. Analyses were conducted from February to November 2022. RESULTS The natural language processing pipeline performed well in identifying recent interpersonal disputes, problems with intimate partners, acute/chronic pain, and intimate partners and immediate family at the scene. For example, the Support Vector Machine model had a mean of 98.1% specificity and 90.5% positive predictive value in classifying a recent interpersonal dispute before suicide. The Gradient Boosting model had a mean of 98.7% specificity and 93.2% positive predictive value in classifying a recent interpersonal dispute before suicide. CONCLUSIONS This study developed a natural language processing pipeline to classify 5 female firearm suicide antecedents using narrative reports from the National Violent Death Reporting System, which may improve the examination of these circumstances. Practitioners and researchers should weigh the efficiency of natural language processing pipeline development against conventional text mining and manual review.

Abstract
The death of a patient by suicide is one of the professional events most feared by psychotherapists and firearms are the most commonly used means of suicide. However, as the number of firearm owners within the United States has increased in recent years, so has the risk of firearm-related suicides. Suicidal patients with easy access to their firearms may give in to the wish to die and end their life with little opportunity for reflection or forethought. Furthermore, because the topic of gun control has become so polarized, patients may not always be open to discussing barriers between themselves and their firearms. Nonetheless, psychotherapists using non-judgmental, respectful, and collaborative lethal means counseling can substantially reduce patient suicides.

Abstract
The Suicide Cognitions Scale (SCS) measures suicide-related beliefs proposed by the Fluid Vulnerability Theory. A recent investigation of a revised version of the SCS (i.e., SCS-R) which omits items explicitly referencing suicide has indicated that the measure is highly influenced by a general factor and may be useful for distinguishing severity levels of suicidal thoughts and behaviors; however, limited concurrent validity studies with a range of suicide-related experiences have been conducted. As such, this study replicated and extended previous psychometric research on the SCS-R in an online survey study with a community sample of N = 10,625 U.S. adults. Results confirmed the unidimensional structure of the SCS-R. Logistic regression analyses indicated that the total score of the SCS-R is useful in distinguishing varying levels of suicidal thoughts and behaviors such as past-month planning for suicide without attempt versus past-month suicide attempt. Implications and limitations are discussed.

Abstract
Suicide by firearm remains one of the leading causes of violence-related injury death in the United States each year. The mortality rate from these injuries is high, resulting in a paucity of outcome data in the literature regarding injuries to the maxillofacial region. This has largely been attributed to a lack of funding for research in this area compared to other leading causes of mortality in the United States. The aim of this study was to detail the authors' experience and approach to complex maxillofacial reconstruction using both local reconstructive methods and microvascular free tissue transfer. A retrospective cohort study was designed, including patients who sustained self-inflicted gunshot wounds to the maxillofacial region between January 1, 2012 and May 1, 2020. Forty-one patients met the inclusion criteria. The majority of the patients were male (87.8%). Mean patient age was 44.2 ± 16.6 years. Alcohol or drugs, and a psychiatric history were present in a majority of the cases. The most involved anatomical region was the midface (75.6% of cases). Seven patients required free tissue transfer for reconstruction, with many needing multiple flaps. Self-inflicted gunshot wounds represent challenging reconstruction scenarios, often in the setting of severe psychological trauma, and require a multidisciplinary team to ensure the optimal outcome.

Abstract
BACKGROUND Firearm suicide is a significant public health problem in the United States of America among the general and veteran populations. Broad-based preventive strategies, including lethal means safety, have been emphasized as a key approach to suicide prevention. Prior research has identified ways to improve the reach and uptake of lethal means safety messages. However, few resources have been created with these lessons in mind. METHODS Louisiana firearm owners and instructors were recruited through a larger project, Veteran-Informed Safety Intervention and Outreach Network, as well as a publicly available database of firearm instructors to participate in focus groups to provide feedback on an existing suicide prevention learning module (developed in Utah) for use by firearm instructors. Their feedback was used to adapt the module, which included a brief video and PowerPoint presentation. Firearm owners and instructors were then invited back for another round of focus groups to provide feedback on this adapted learning module. Team-based rapid qualitative analysis was conducted to identify themes across transcripts from these four focus groups. RESULTS Firearm owners and instructors agreed on several key themes, including the importance of messenger relatability and aligning the lethal means safety message with firearm owner values. Feedback suggested these themes were adequately addressed in the adapted learning module and contributed to overall module acceptability. The final theme, present across the original and adapted learning modules (i.e., Utah and Louisiana), was openness to further information and training on firearm suicide prevention. CONCLUSION Consistent with a public health approach to suicide prevention, the current study used stakeholder engagement to develop a suicide prevention learning module perceived as representative, accurate, and acceptable to Louisiana firearm owners and instructors. These findings can be used to inform firearm suicide prevention efforts in other states.

Abstract
IMPORTANCE Understanding mental health and substance use treatment seeking and suicidality among suicide decedents is important to determine prevention efforts. OBJECTIVE To evaluate differences in treatment seeking and suicidality between suicide decedents who died by firearms and those who died by other methods. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional data were collected on 234 652 suicide decedents from 2003 to 2018. Participant information was reported by their state of residence to the National Violent Death Reporting System. Statistical analysis was performed from July 1, 2021, to January 21, 2022. MAIN OUTCOMES AND MEASURES Main outcomes were treatment for mental health and substance use at time of death, previous treatment for mental health and substance use, history of suicidal ideation or plans, history of suicide attempts, and disclosure of suicidal ideation or plans. RESULTS A total of 234 652 participants (182 520 male [77.8%]; 205 966 White [87.8%]; mean [SD] age, 46.3 [18.2] years [range, 3-112 years]) were included in this study. Compared with suicide decedents who died by another method (n = 117 526 [50.1%]), those who died by firearm (n = 117 126 [49.9%]) were more likely to have disclosed thoughts or plans of suicide within the month prior to death (odds ratio [OR], 1.16 [95% CI, 1.13-1.18]) and were less likely to have previously attempted suicide (OR, 0.44 [95% CI, 0.43-0.46]). Compared with those who died by poisoning, those who used a firearm were more likely to have had a history of suicidal thoughts or plans (OR, 1.19 [95% CI, 1.15-1.23]) and to have disclosed their thoughts or plans of suicide within the month prior to death (OR, 1.06 [95% CI, 1.03-1.10]). Compared with those who died by hanging, those who used a firearm were more likely to have disclosed their thoughts or plans of suicide to another person within the month prior to their death (OR, 1.14 [95% CI, 1.11-1.17]). CONCLUSIONS AND RELEVANCE These findings provide information that suggests who is at risk to die by firearm suicide. Community-based interventions in suicide prevention could help reduce access to firearms during a time of crisis. The finding that firearm suicide decedents were more likely to disclose their suicidal thoughts or plans provides an important avenue for prevention.

Abstract
PURPOSE Gun access among youth may contribute to youth suicide deaths by increasing practical capability. The present work examines the association between youth gun and weapon carrying behavior and suicide rates among those aged 24 years and younger. METHODS Using the 2005-2017 Youth Risk Behavior Surveillance System, the associations over time between youth gun and weapon carrying and youth suicide rates were examined. A series of generalized estimating equations were used to examine population-level associations between states and across time. RESULTS As anticipated youth gun carrying behavior was a significant contributor to the prediction of firearm suicide rates for those aged 24 years and younger, with higher rates of youth gun carrying associated with higher suicide rates. Youth gun carrying was not a significant predictor of overall suicide rates for those aged 24 years and younger. Youth weapon carrying (which includes guns, knives, and other weapons) was a significant predictor of both firearm-specific and overall suicide rates for those aged 24 years and younger. CONCLUSIONS Previous research has linked youth gun carrying behavior to past year suicide attempts. This study represents the first attempt at examining the associations between youth gun carrying behavior and suicide mortality among the young. In line with our expectations, states with higher percentages of youth reporting gun and weapon carrying behavior had greater rates of suicide among the young (those aged 24 years and younger). The present work points toward the importance of limiting youth access to firearms in reducing suicide mortality.

Abstract
The present study sought to determine the extent to which the message or messenger is more important for news media portrayal of gun violence prevention. Exploratory analyses also examined factors related to Fox News and MSNBC credibility. Participants (N = 3,500) were US adults matched to the 2010 US Census on several demographic variables. Two mock headlines were presented: "Gun violence is result of mental health problems" and "Storing firearms in a safe can help prevent suicides." Headlines were reported to be from either Fox News or MSNBC. Participants then rated accuracy of the headline and credibility of the news source. Headline content did not predict perceived accuracy of the headline. Perceived credibility of the messenger was associated with perceived accuracy for both mock headlines. Exploratory analyses indicated several demographic factors related to Fox News and MSNBC credibility. Regardless of the content of a headline, the degree to which participants perceived it as accurate was associated with how credible they believed the source to be. These findings highlight the importance of credible media portrayal of accurate information on gun violence prevention.

Abstract
INTRODUCTION The aim was to investigate psychiatric health care utilization two years before death by suicide among individuals with previous suicide attempts (PSA) compared with those without (NSA). METHOD A retrospective population-based cohort study was conducted including 484 individuals who died by suicide in Sweden in 2015 and were in contact with psychiatric services within the two years preceding death, identified through the Cause of Death register. Data on psychiatric health care two years before death, including suicide attempts according to notes in the medical record was used. Associations between having at least one PSA vs. NSA and health care utilization were estimated as odds ratios (OR) with 95% confidence intervals (CI) by logistic regression analyses. RESULTS Of the 484 individuals included, 51% had PSA. Those with PSA were more likely than NSA to have received a psychiatric diagnosis [OR 1.96 (CI 95% 1.17-3.30)], to have ongoing psychotropic medication [OR 1.96 (CI 95% 1.15-3.36)] and to have been absent from appointments during the last three months [1.97 (1.25-3.13)]. In addition, elevated suicide risk was more often noted in the psychiatric case records of those with a PSA than those without [OR 2.17 (CI 95% 1.24-3.79)]. CONCLUSION The results underline the importance of improved suicide risk assessment as well as thorough diagnostic assessment and when indicated, psychiatric treatment as suicide preventive interventions regardless of PSA. Furthermore, the larger proportion of absence from appointments in individuals with PSA may indicate a need of improved alliance between psychiatric care providers and individuals with PSA.HIGHLIGHTSBeing assessed with elevated suicide risk was more common among those with previous attempt/s (PSA).One-fifth of all with no previous attempt (NSA) had no psychiatric diagnosis, compared to one in ten in those with PSA.Receiving psychotropic medication was more common among those with PSA.

Langmann C. Suicide, firearms, and legislation: A review of the Canadian evidence. Prev Med 2021; 152:106471.

Abstract
Suicide accounts for approximately 4000 deaths a year in Canada, of which about 16% of those are suicide using a firearm. Canada has undertaken legislative efforts to regulate and control firearms, Bill C-51 in 1977 and Bills C-17 and C-68 in 1991 and 1995. Regulatory approaches that decrease the availability of firearms are hypothesized to reduce suicide by firearm however the substitution effect suggests it is possible that people may substitute other methods of suicide in place. Canadian studies on associations between legislation, regulation, and suicide rates have been published over the last three decades, and a search revealed thirteen that met the criteria. Seven studies examined the association between Bill C-51 and suicide rates and found that while rates of suicide by firearm appeared to have declined in association with regulations, there appears to be a substitution effect into other methods and no overall change in suicide rates. Six studies examining the effects of Bill C-17 and C-68 revealed a decrease in the rates of suicide by firearms, with a corresponding increase in non-firearms suicide rates and no decrease in overall suicide rates. One study even suggested no associated decrease in firearm suicide rates with an increasing rate of suicide by hanging possibly due to changes in preferences. These results suggest legislation has mixed effects on firearm suicide rates and may not alone reduce overall suicide in Canada.

"Lock and Protect": Development of a Digital Decision Aid to Support Lethal Means Counseling in Parents of Suicidal Youth. Front Psychiatry 2021; 12:736236. [PMID: 34690841 PMCID: PMC8528190 DOI: 10.3389/fpsyt.2021.736236] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Accepted: 08/27/2021] [Indexed: 12/31/2022] Open
Abstract
Objective: Reducing access to lethal methods is an effective suicide prevention strategy that is often neglected in routine care. Digital interventions have shown promise for addressing such gaps in care; and decision aids have proven useful for supporting complicated health-related decisions, like those involving lethal means restriction. This article describes a parent/caregiver-facing web-based decision aid, the development process, and user testing. Method: A user-centered, participatory, mixed methods development design was employed. Beginning with an adult-focused decision aid developed by members of our team, we assessed ten iterations of the parent/caregiver decision aid with stakeholders (N = 85) using qualitative interviews and quantitative surveys. Stakeholders included: parents/caregivers whose children had histories of suicidal episodes before age 25, young adults with histories of suicidal thoughts/behaviors, firearm owners/representatives from firearm stores/ranges/groups, mental and medical health care providers, and emergency responders. Results: The final "Lock and Protect" decision aid was viewed as "useful for changing access to lethal means" by 100% of participants. Ninety-four percent of participants rated the information on reducing access to lethal means as good to excellent, and 91% rated the information on storage options as good to excellent. Qualitative feedback underscored a preference for offering this digital tool with a "human touch," as part of safety and discharge planning. Conclusions: "Lock and Protect" is a user-friendly web-based tool with potential for improving rates of lethal means counseling for parents/caregivers of suicidal youth and ultimately reducing pre-mature deaths by suicide.

Abstract
OBJECTIVE The present study sought to determine which painful and provocative events differentiated those with suicidal ideation from those who attempted suicide. Additionally, it presents a novel way of utilizing the Painful and Provocative Scale (PPES) by looking at items dichotomously as experienced or not experienced, instead of the frequency at which they are experienced. METHOD Participants (N = 666) were recruited as part of a large online study seeking to understand suicide risk across multiple high-risk groups (i.e., veterinarians, military service members, transgender individuals, and gun owners) for suicide. Participants in the present study were predominately white, female, and heterosexual. RESULTS First, the PPES was examined as a dichotomous measure and results indicate that experiencing physical or sexual abuse, tying a noose, using intravenous drugs, or having injuries that required medical attention were associated with greater odds of attempting suicide; shooting a gun was associated with decreased odds. Next, the PPES was examined as a scale measure and findings indicate that increased exposure to rock climbing, experiencing physical or sexual abuse, or using intravenous drug were associated with increased odds of attempting suicide; while increased exposure to shooting a gun was associated with decreased odds. CONCLUSIONS The present study adds to the literature on the ideation-to-action framework and provides evidence considering the frequency of experiences using the Painful and Provocative Event Scale may not provide substantial information beyond dichotomous scoring.

Abstract
BACKGROUND Although studies have investigated the association between alcohol use and violent behaviors such as weapon carrying, few studies have examined the association between age at first alcohol use and weapon-carrying among adolescents. The objective of this study was to investigate the association between age at first alcohol use and weapon carrying among adolescents. METHODS Data for this study came from the 2019 Youth Risk Behavior Survey. An analytic sample of 13,442 adolescents aged 14-18 years old (51% female) was analyzed using binary logistic regression. The outcome variable investigated in this study was weapon carrying during the past 30 days, and the main explanatory variable investigated was age at first alcohol use. RESULTS Of the 13,442 adolescents, 13.5% carried a weapon during the past 30 days, and 15.4% reported having their first alcoholic drink before age 13. In the multivariable logistic regression, adolescents who reported having alcohol before age 13 had more than double the odds of carrying a weapon when compared to those who never had alcohol before age 13 (AOR = 2.32, p < .001, 95% CI = 1.87-2.89). Other significant factors associated with weapon carrying include male gender, victim of bullying, teen dating violence, sexual violence, suicidal ideation, and history of substance use. Adolescents who self-identified as Black/African American or Hispanic were significantly less likely to carry a weapon when compared to adolescents who self-identified as non-Hispanic White. CONCLUSION The findings of this study underscore the importance of developing age appropriate intervention strategies to curb early initiation of alcohol use and weapon carrying among adolescents.

Abstract
BACKGROUND Limited research suggests that rates of suicide death among transgender people may be higher than their nontransgender peers. OBJECTIVE The objective of this study was to compare rates of suicide deaths by different means between transgender and nontransgender patients. RESEARCH DESIGN This secondary analysis used VHA administrative and electronic health record (EHR) data from October 1, 1999 through December 31, 2016. SUBJECTS Transgender patients (n=8981) were categorized as such based on a set of International Classification of Disease codes, and a comparison sample was selected by randomly choosing 3 nontransgender patients (n=26,924). MEASURES AND ANALYSES Cause and date of death data are from the National Death Index. Because of low frequencies amid different methods of suicide death, we combined categories into self-poisoning; hanging, strangulation and suffocation; discharge of firearms; and self-harm by all other and unspecified means. We conducted Cox regression analyses to model time-to-event for each method of suicide, adjusted for age, sex based on EHR, race, ethnicity, marital status, and whether patients had ever been diagnosed with depression. RESULTS Among transgender patients, 73 died by suicide (22 female EHR-based sex, 51 male EHR-based sex), and among nontransgender patients, 71 died by suicide (4 female EHR-based sex, 67 male EHR-based sex). In adjusted models, transgender patients had significantly greater hazards of death by self-poisoning and firearms than their nontransgender peers. CONCLUSIONS Differences in methods of suicide death suggest that firearms and self-poisoning may be specific areas of concern for transgender individuals experiencing suicidal crisis, which underscore needs for examining effective delivery of evidence-based care.

Abstract
IMPORTANCE Because more than one-third of people making nonfatal suicide attempts do not receive mental health treatment, it is essential to extend suicide attempt risk factors beyond high-risk clinical populations to the general adult population. OBJECTIVE To identify future suicide attempt risk factors in the general population using a data-driven machine learning approach including more than 2500 questions from a large, nationally representative survey of US adults. DESIGN, SETTING, AND PARTICIPANTS Data came from wave 1 (2001 to 2002) and wave 2 (2004 to 2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). NESARC is a face-to-face longitudinal survey conducted with a national representative sample of noninstitutionalized civilian population 18 years and older in the US. The cumulative response rate across both waves was 70.2% resulting in 34 653 wave 2 interviews. A balanced random forest was trained using cross-validation to develop a suicide attempt risk model. Out-of-fold model prediction was used to assess model performance, including the area under the receiver operator curve, sensitivity, and specificity. Survey design and nonresponse weights allowed estimates to be representative of the US civilian population based on the 2000 census. Analyses were performed between May 15, 2019, and June 10, 2020. MAIN OUTCOMES AND MEASURES Attempted suicide in the 3 years between wave 1 and wave 2 interviews. RESULTS Of 34 653 participants, 20 089 were female (weighted proportion, 52.1%). The weighted mean (SD) age was 45.1 (17.3) years at wave 1 and 48.2 (17.3) years at wave 2. Attempted suicide during the 3 years between wave 1 and wave 2 interviews was self-reported by 222 of 34 653 participants (0.6%). Using survey questions measured at wave 1, the suicide attempt risk model yielded a cross-validated area under the receiver operator characteristic curve of 0.857 with a sensitivity of 85.3% (95% CI, 79.8-89.7) and a specificity of 73.3% (95% CI, 72.8-73.8) at an optimized threshold. The model identified 1.8% of the US population to be at a 10% or greater risk of suicide attempt. The most important risk factors were 3 questions about previous suicidal ideation or behavior; 3 items from the 12-Item Short Form Health Survey, namely feeling downhearted, doing activities less carefully, or accomplishing less because of emotional problems; younger age; lower educational achievement; and recent financial crisis. CONCLUSIONS AND RELEVANCE In this study, after searching through more than 2500 survey questions, several well-known risk factors of suicide attempt were confirmed, such as previous suicidal behaviors and ideation, and new risks were identified, including functional impairment resulting from mental disorders and socioeconomic disadvantage. These results may help guide future clinical assessment and the development of new suicide risk scales.

Abstract
Conducting case-control studies using the National Violent Death Reporting System (NVDRS) has the potential to introduce selection bias and misclassification through control selection. Some studies that use NVDRS compare groups of individuals who died by one mechanism, intent or circumstance, to individuals who died by another mechanism, intent or circumstance. For aetiological studies within NVDRS, the use of controls who had a different type of violent death has the potential to introduce selection bias, while relying on narrative summaries for exposure measurement may result in misclassification. We discuss these two methodological issues, and identify an unusual circumstance in which selection of live controls within NVDRS can be employed.

Abstract
Although a history of a suicide attempt is the strongest predictor of future suicide attempts, not all adolescents who make an attempt engage in repetitive suicidal behavior. The present study sought to determine whether certain characteristics of a first suicide attempt (e.g., age of first attempt, method of attempt used, intent seriousness, medical lethality, and receipt of treatment after attempt) can distinguish between adolescents who make single versus multiple suicide attempts. Adolescents (N = 95) who were psychiatrically hospitalized and their guardian completed a diagnostic interview to gather information on all lifetime suicide attempts. A multivariate hierarchical logistic regression was conducted, predicting single attempt versus multiple attempt status. Of the first-attempt characteristics examined, only age of first attempt, OR = 0.33, 95% CI [0.17-0.63], p = .001, and receipt of treatment following attempt, OR = 0.28, 95% CI [0.09-0.88], p = .028, significantly distinguished SA vs. MA status, even after controlling for current age and depression at the time of first attempt. Female and White participants were overrepresented in this sample, which limits generalization to more heterogenous and diverse samples. The cross-sectional nature of data introduces the potential for retrospective recall bias. Younger age of first attempt and lack of receipt of mental health treatment following a first attempt were associated with multiple attempt status. These findings highlight the importance of early mental health screening, parental psychoeducation, and linkage to mental health care after a suicide attempt.

Abstract
BACKGROUND Much of suicide research focuses on suicide attempt (SA) survivors. Given that more than half of the suicide decedent population dies on their first attempt, this means a significant proportion of the population that dies by suicide is overlooked in research. Little is known about persons who die by suicide on their first attempt-and characterizing this understudied population may improve efforts to identify more individuals at risk for suicide. METHODS Data were derived from the National Violent Death Reporting System, from 2005 to 2013. Suicide cases were included if they were 18-89 years old, with a known circumstance leading to their death based on law enforcement and/or medical examiner reports. Decedents with and without a history of SA were compared on demographic, clinical, and suicide characteristics, and circumstances that contributed to their suicide. RESULTS A total of 73 490 cases met criteria, and 57 920 (79%) died on their first SA. First attempt decedents were more likely to be male, married, African-American, and over 64. Demographic-adjusted models showed that first attempt decedents were more likely to use highly lethal methods, less likely to have a known mental health problem or to have disclosed their intent to others, and more likely to die in the context of physical health or criminal/legal problem. CONCLUSIONS First attempt suicide decedents are demographically different from decedents with a history of SA, are more likely to use lethal methods and are more likely to die in the context of specific stressful life circumstances.

Abstract
OBJECTIVE Firearm means safety strategies, such as safe storage, are effective in reducing suicide rates but are not widely implemented in the United States. This study examined the association between reason for firearm ownership, beliefs about firearm ownership and storage and suicide risk, willingness to engage in means safety, and current firearm storage practices. METHOD A sample of 300 American firearm owners (53.0% male; 82.3% White; Mage = 36.11, age range = 20-69) completed an online survey via Amazon's Mechanical Turk (mTurk) program. RESULTS Firearm owners who own a firearm for protection, compared to owning a firearm for other reasons, (1) endorsed decreased belief in the relationship between firearm ownership and storage and suicide risk, (2) were less willing to engage in the means safety measures of storing firearms safely and allowing a trusted individual to temporarily remove firearms from the home, and (3) were more likely to store their firearms loaded. CONCLUSIONS Reason for firearm ownership influences views regarding firearms and suicide, willingness to engage in firearm means safety, and firearm storage practices. It is essential to understand how differences in reason for firearm ownership impact these outcomes so appropriate, efficacious messaging can be developed and implemented.

Abstract
BACKGROUND Rural veterans are at increased risk for dying by suicide compared with urban veterans, yet interventions for preventing suicide among rural veterans have been limited. OBJECTIVES (1) Describe how Together With Veterans (TWV), a community-based intervention to prevent suicide among veterans in rural communities, aligns with the VA National Strategy for Preventing Veteran Suicide; (2) share lessons learned while beginning to implement TWV in rural communities. METHODS Together With Veterans is being implemented in four rural communities and comprises six suicide prevention best practices: (1) reducing stigma and promoting help-seeking; (2) lethal means safety, with an emphasis on firearms; (3) gatekeeper training; (4) training primary care providers; (5) improving access to crisis services; and (6) enhancing support for high-risk veterans. RESULTS Together With Veterans best practices align with most, but not all, of the strategies in the VA National Strategy for Preventing Veteran Suicide. Community veteran partners have shown a willingness to collaborate and provide local leadership, enthusiasm, and a sense of duty. CONCLUSIONS By supporting and facilitating local veteran leaders and their community partners in increasing suicide prevention knowledge, public awareness, and resources, we propose that TWV offers an acceptable and feasible approach that builds on the strengths of rural communities. Systematic evaluation is warranted.

Abstract
OBJECTIVE Veterans die by suicide at a higher rate than the U.S. population, and veterans more frequently use a firearm as the suicide method. Consequently, firearm accessibility and storage represent important prevention considerations. This project aimed to explore the implementation of suicide prevention efforts among veterans who went on to die by suicide, with and without the use of a firearm, and to identify factors that differentiated veteran suicide decedents to help inform suicide prevention efforts. METHODS Data from the Veteran Health Administration Behavior Health Autopsy Program was analyzed for 97 veteran suicide decedents. RESULTS Results demonstrated that veterans who used a firearm for suicide were less likely to have engaged in suicide prevention efforts overall and were less likely to have received lethal means safety counseling / safety planning. Veterans who died by firearm had lower levels of notable risk factors (e.g., prior suicide attempt, no-shows for appointments), however were more likely to have a documented unsecured firearm in their home. CONCLUSION These findings support the benefit of broadening the reach of suicide prevention efforts, especially for high-risk veterans with access to firearms.

Abstract
Firearms account for approximately half of all suicides in the United States and are highly lethal, widely available, and popular; thus, are an ideal candidate for targeted means safety interventions. However, despite their value as a suicide prevention tool, firearm means safety strategies are not widely utilized, possibly due to factors which impede openness to their use. This study examines the relationship between region, political beliefs, and openness to firearm means safety in a sample of 300 American firearm owners. Overall, firearm owners were more willing to engage in means safety for others than for themselves and to store firearms safely than temporarily remove them from the home. Social policy views and region were significantly associated with openness to firearm means safety measures, however, economic policy views were not. This study provides further context for the development and implementation of efficacious means safety measures capable of overcoming potential barriers to their use.

Abstract
Suicidal behaviors among adolescents in the United States are the second leading cause of death and has been steadily increasing over the years. Although access to and possession of a weapon may facilitate the transition from suicidal ideation to a suicide attempt, few studies have examined the association between weapon carrying and suicide attempts among adolescents. The objective of this study was to examine the association between weapon carrying on school property and suicide attempt among adolescents. Data for this study came from the 2017 Youth Risk Behavior Surveillance System. A sample of 14,547 adolescents aged 14-18 years old (50.5% female) was analyzed using logistic regression. Of the 14,547 adolescents, 4% carried a weapon on school property, and 7.7% attempted suicide during the past 12 months. In the multivariate logistic regression, adolescents who reported carrying a weapon on school property had more than double the odds of attempting suicide when compared to their counterparts who did not carry a weapon on school property. Other significant predictors of suicide attempt include sexual minority, history of forced sexual intercourse, school bullying and cyberbullying victimization, feeling sad or hopeless, and substance use. Examining the association between weapon carrying and suicide attempt among adolescents would contribute to early identification of adolescents who are likely to engage in suicidal behaviors.

Abstract
Firearm legislation is associated with statewide suicide rates; however, prior research has often relied upon older data and categorical legislative grades while also failing to consider the nuanced role of firearm ownership. Therefore, the robust literature base on legislation and suicide has not directly examined regarding the extent to which the value of legislation hinges upon the rate of firearm ownership in a given state. The current study examined 2015 US statewide firearm legislation strength scores from Giffords Law Center to Prevent Gun Violence and 2016 statewide suicide rates from the Centers for Disease Control and Prevention. Firearm legislation strength was inversely associated with statewide overall and firearm suicide rates, but not with non-firearm suicide rates. Firearm ownership rates moderated the association between firearm legislation strength and statewide overall suicide rates. Specifically, firearm legislation strength was inversely associated with statewide overall suicide rates at mean and high levels of firearm ownership. Findings support the potential utility of firearm legislation as part of a national effort to decrease US suicide deaths, particularly in areas with higher firearm ownership rates.

Abstract
Although some studies have examined the association between prescription opioid misuse and mental health outcomes, few studies have examined the effects of prescription opioid misuse on suicidal behaviors among adolescents. The objective of this study was to examine the association between prescription opioid misuse and suicidal ideation, suicide plan, and suicide attempt among adolescents. Data for this study came from the 2017 Youth Risk Behavior Surveillance System. A sample of 8830 adolescents aged 14-18 years (50.9% female) were analyzed using logistic regression with suicidal ideation, suicide plan, and suicide attempt as outcome variables and prescription opioid misuse as the main explanatory variable. Of the 8830 adolescents, 13.3% ever misused prescription opioids; 17.7% experienced suicidal ideation, 13.3% made a suicide plan, and 6.5% attempted suicide during the past 12 months. In the multivariate logistic regression models, adolescent students who misused prescription opioids were 1.50 times more likely to have experienced suicidal ideation, 1.44 times more likely to have made a suicide plan, and 1.58 times more likely to have attempted suicide during the past 12 months when compared to their counterparts who did not misuse prescription opioids. Other significant predictors of suicidal behaviors include sexual minority, history of sexual assault, traditional bullying and cyberbullying victimization, feeling sad or hopeless, cigarette smoking, and illicit drug use. The findings of the present study demonstrate the harmful effects of prescription opioid misuse and its association with suicidal behaviors among adolescents.

Abstract
PURPOSE The purpose of the study was to explore variability in circumstances around suicide deaths among youth and young adults by sexual/gender identity category (gay male, lesbian/gay female, bisexual male, bisexual female, transgender male, transgender female, non-LGBT [lesbian, gay, bisexual, and transgender] male, and non-LGBT female). METHODS Secondary analysis of National Violent Death Reporting System (NVDRS) data for all 12- to 29-year-olds who died by suicide in NVDRS participating states. Coverage begins in 2013, the year that NVDRS began coding for sexual orientation and transgender status, and ends in 2015, the latest year of NVDRS data available. The valid sample was limited to cases in which sexual orientation or transgender status could be determined postmortem, n = 2,209. RESULTS Almost one quarter (24%) of 12- to 14-year-olds who died by suicide were LGBT, whereas only 8% of 25- to 29-year-olds who died by suicide were LGBT. Most non-LGBT males and bisexual males died by firearm and had intimate partner problems contribute to their deaths. Non-LGBT females and LGBT persons other than bisexual males were generally less likely to use firearms. They were also more likely to have psychiatric diagnoses, prior suicidality, and family problems contributing to their deaths. Rates of many circumstances varied widely among LGBT subgroups. CONCLUSIONS The LGBT versus non-LGBT suicide disparity is greatest at younger ages, and each LGBT subgroup has its own specific risk profile for suicide. Suicide prevention and intervention efforts targeted at LGBT youth may increase their effectiveness by attending to these distinct risk profiles.

Abstract
The objectives of this study were to identify factors that contribute to (1) remission from suicidal ideation, and (2) remission from suicide attempt, among Canadians with a lifetime history of suicide attempt. Data for this study came from Statistics Canada's nationally representative 2012 Canadian Community Health Survey-Mental Health. A sample of 769 adult respondents who had ever attempted suicide was analyzed with remission from past year suicidal ideation and remission from past year suicide attempt as outcome variables. Of the 769 respondents who had ever attempted suicide, more than two-thirds (69%) were free from suicidal ideation within the past year, and approximately 87% were free from suicide attempts within the past year. Compared to men, odds were 2.66 times greater for women to be free of suicide attempt and 2.65 times greater to be free of suicidal ideation in the past year. Older age, being free of sleep problems and major depressive episode, having no history of chronic childhood physical abuse, and having two or fewer previous suicide attempts were associated with higher odds of remission from both suicide attempt and ideation in the past year.

Abstract
BACKGROUND Sweden's firearm legislation obligates physicians to report patients that are deemed unsuitable to possess a firearm. This study aimed to explore the involvement of firearm use in firearm fatalities and to evaluate physician reporting concerning cases of firearm deaths. METHODS Fatal firearm suicides and homicides in Sweden were studied for the years 2012-2013, accidental deaths and undetermined manner of deaths for the period 1987-2013. Police reports and autopsy protocols were collected from the National Board of Forensic Medicine, health care data in 1 year before the fatality from the National Board of Health, and information about physician reports and firearm licences from the Swedish Police. RESULTS A total of 291 firearm deaths (213 suicides, 52 accidental deaths, 23 solved homicides and 3 cases with undetermined manner of death) were identified. Firearm suicides were positively correlated with the number of licensed firearm owners. Legal firearm use predominated in firearm suicides and accidental deaths, illegal in homicides. No suicide victim or shooter in an accidental death was previously reported by a physician to the police according to the firearm law. The majority of the shooters in accidental deaths and suicides had no registered health care visits. Less than half (42%) of all suicide victims had a previous health care contact due to mental health problems. CONCLUSIONS Not one single suicide victim nor any shooter in accidental deaths in the present study had been reported according to the firearm law, bringing the evidence of a suboptimal framework.

Abstract
Firearms account for half of all U.S. suicide deaths, but research on mechanisms through which firearms confer risk is limited. Although research has indicated firearm ownership and the unsafe storage of firearms are associated with an elevated risk of suicide, such research cannot provide insight into the extent to which a history of using a gun plays a role. We recruited a community sample (N = 100; 76% female; 44% Black) oversampled for prior suicidal behavior in a high gun ownership state (Mississippi). Consistent with hypotheses, a greater number of lifetime experiences of firing a gun were associated with elements of the capability for suicide (fearlessness about death, pain tolerance, pain persistence) and lifetime suicide attempts, but not with suicide ideation or simple pain detection. These findings indicate that guns may confer risk of suicide in part through increased comfort and aptitude with the weapon, a notion consistent with the construct of practical capability. Furthermore, these findings are consistent with research indicating that guns do not cause healthy individuals to become suicidal, but rather increase risk among already suicidal individuals. Overall, our findings highlight the importance of considering practical experience with guns as well as simple ownership and storage methods.

Abstract
OBJECTIVE A suicide attempt is at least somewhat life-threatening by definition and is, for some, traumatic. Thus, it is possible that some individuals may develop posttraumatic stress disorder (PTSD) from a suicide attempt. METHOD In this article, we consider whether one's suicide attempt could fulfill Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for a PTSD Criterion A event and contribute to the development of attendant PTSD symptoms (e.g., flashbacks, avoidance, shame/guilt, nightmares); discuss theoretical models of PTSD as they relate to suicide attempts; reflect on factors that might influence rates of suicide attempt-related PTSD; highlight methodological limitations that have hampered our understanding of suicide attempt-related PTSD; and posit areas for future scientific and clinical inquiry. RESULTS Strikingly, the degree to which a suicide attempt leads to PTSD is unknown. CONCLUSIONS We conclude with a call for research to systematically assess for suicide attempts alongside other potentially traumatic experiences (e.g., combat exposure, rape) that are included in standardized PTSD assessments.

Abstract
Extant literature provides evidence for the frequent use and lethality of firearms in suicide and the ability of means safety measures to prevent suicides; however, little evidence exists to provide an understanding of the characteristics that differentiate suicide decedents who die by firearm from those who die by other methods. In this study, we build on prior findings regarding the characteristics of those who die by firearms by examining the relationship between social and economic policy views and both firearm ownership and death by firearm in a sample of 160 American suicide decedents. We hypothesized that individuals with more conservative social and economic policy views would have higher rates of firearm ownership and would be more likely to die by firearm than would individuals with more liberal social and economic policy views. Furthermore, we hypothesized that differences in the likelihood of dying by a firearm would be accounted for by firearm ownership, providing preliminary evidence for a specific mechanism through which risk for death by firearm is conferred. As expected, suicide decedents with conservative social and economic policy views owned firearms at higher rates than did decedents with moderate or liberal views. The use of a firearm, the most common method across all decedents, was higher in individuals with conservative policy views. These results represent a novel angle from which to consider the importance of means safety efforts focused on firearm ownership and storage and limit concerns that firearm specific suicide research has relied too heavily on samples that are not representative of typical American suicide decedents.

Abstract
The capability to enact lethal self-harm has recently been highlighted as a critical risk factor for suicidal behavior. Klonsky and May's (2015) three step theory of suicide (3ST) expanded upon the construct of the capability for suicide by dividing it into categories: dispositional, acquired, and practical. The current study examined constructs of Patrick and colleagues' (2009) triarchic model of psychopathy as indicators of dispositional capability in gun owners, a sample at heightened risk for death by suicide (Anestis and Houtsma, 2017). We anticipated that specific psychopathic traits would exhibit robust associations with other components of the capability for suicide. In a sample of 300 gun-owning adults, Boldness was uniquely related to all indicators of practical capability in both male and female gun owners, and a Boldness*Meanness interaction predicted the highest levels of some capability components. These results are consistent with theoretical conceptualizations of the triarchic model. Our findings indicate that, among US gun owners, dispositional factors may impact comfort with and aptitude with guns, which may enhance our understanding of which gun owners are at the greatest risk of gun suicide should they develop suicidal thoughts.

Abstract
An extensive body of research has demonstrated an association between gun ownership and suicide that extends beyond the effects of a range of covariates. We aimed to expand on extant research by examining the extent to which gun ownership predicts statewide overall suicide rates beyond the effects of demographic, geographic, religious, psychopathological, and suicide-related variables. By extending the list of covariates utilized, considering those covariates simultaneously, and using more recent data, we sought to present a more stringent test. Gun ownership predicted statewide overall suicide rates, with the full model accounting for more than 92% of the variance in statewide suicide rates. The correlation between firearm suicide rates and the overall suicide rate was significantly stronger than the correlation between nonfirearm suicide rates and the overall suicide rate. These findings support the notion that access to and familiarity with firearms serves as a robust risk factor for suicide. Therefore, means safety efforts aimed at reducing accessibility and increasing safe storage of firearms would likely have a dramatic impact on statewide overall suicide rates.

Abstract
Suicide is one of the leading causes of death and represents a significant public health problem world-wide. Individuals who attempt or die by suicide represent a highly heterogeneous population. Recently, efforts have been made to identify sub-populations and variables to categorize them. A popular dichotomy in suicide research of the past years is violent versus non-violent suicide - based on the method. This dichotomy is important given that there is an association between method of attempted suicide and risk of subsequent death by suicide. The differentiation concerning suicide methods is also critical regarding preventive efforts. In this review, we have tried to approach the concept of violent suicide from different perspectives, including a discussion about its definition and overlapping categories. In addition, we have critically discussed aggression as underlying trait, the question of intent to die, and sociodemographic, environmental, neuropsychological, and neurobiological factors potentially associated with violent suicide.

Abstract
BACKGROUND Firearm ownership and unsafe storage increase risk for suicide. Little is known regarding factors that influence storage practices and willingness to engage in means safety. METHODS Utilizing Amazon's Mechanical Turk program, we recruited an online sample of 300 adults living in the US who own at least one firearm. Firearm storage practices and openness to means safety measures were assessed using items designed for this study. Data were collected and analyzed in 2017. RESULTS Firearms stored in non-secure locations and without a locking device were associated with lower beliefs in the relationship between firearm storage and suicide risk. Fearlessness about death moderated the association between current secure versus non-secure storage and beliefs regarding firearm storage and suicide risk, in that storage practices and beliefs were more strongly related at higher levels of fearlessness about death. For both secure and locked storage of a firearm, there was a significant indirect effect of current storage practices on willingness to engage in means safety in the future through current beliefs regarding the relationship between firearm storage and suicide risk. Unsafe storage practices were largely associated with an unwillingness to store firearms more safely or to allow a trusted peer to temporarily store the firearm outside the home in order to prevent their own or someone else's suicide. LIMITATIONS Self-report and cross-sectional data were used. Results may not generalize to non-firearm owners. CONCLUSIONS Firearm owners are prone to inaccurate beliefs about the relationship between firearms and suicide. These beliefs may influence both current firearm storage practices and the willingness to engage in means safety.

Abstract
In this study, we compared United States military decedents who died by suicide on their first attempt with decedents who had made multiple attempts. Death investigation files for 217 United States Air Force (USAF) personnel who died by suicide between 1996 and 2006 were coded for demographic, psychosocial, and psychiatric characteristics. Among USAF suicide decedents, 77% died by suicide on their first attempt and 23% had a documented history of at least one prior attempt. Decedents with a history of prior attempts were more likely to have an interpersonal stressor within 3 months of death and were twice as likely to have a documented Axis I diagnosis. There were few differences between military suicide decedents based on history of prior attempts. Further research is needed to inform military suicide prevention endeavors.

Abstract
This paper reviews current literature on the links between personality pathology and intentional self-harm, including nonsuicidal self-injury (NSSI) and suicidal behaviors. Specifically, this review highlights recent advances stemming from longitudinal, epidemiological, and health registry studies, as well as emerging research on pathological personality traits and intentional self-harm, and integrates current knowledge across dimensional and categorical frameworks to provide recommendations for clinical practice and future research. This review provides strong evidence that personality disorders marked by intense and unstable negative affect, detachment/low extraversion, aggression/hostility, and specific facets of impulsivity may be considered risk factors for suicidal behaviors. Further, there is some evidence of a stronger relation between maladaptive personality traits and suicidal versus non-suicidal intentional self-harm.

Abstract
Firearms are utilized in approximately half of all US suicides, making them a serious public health concern and a target of suicide prevention efforts. Practical capability influences the transition from suicidal ideation to action and is particularly relevant to firearm suicide. Firearm ownership, experience using firearms, unsafe firearm storage, and high cultural acceptability of firearms increase risk for death by firearm suicide. Means safety strategies, which emphasize the reduction of practical capability for suicide through the limitation of access to and safe storage of firearms, are effective in preventing suicide and include interventions such as lethal means counseling, firearm legislation, and promoting safe storage practices. Public health interventions aimed at reducing firearm suicide are critical topics for continued research.

Abstract
Firearms account for approximately half of all US suicide deaths each year despite being utilized in only a small minority of suicide attempts. We examined the extent to which overall suicide rates fluctuated relative to firearm and non-firearm suicide rates across a period of 16years (1999-2015). We further tested the notion of means substitution by examining the association between firearm suicide rates and non-firearm suicide rates. Lastly, we examined the extent to which the presence of specific laws related to handgun ownership previously shown cross-sectionally to be associated with lower suicide rates (universal background checks, mandatory waiting periods) were associated with an attenuated trajectory in suicide rates across the study period. As anticipated, whereas decreases in firearm suicide rates were associated with decreases in overall suicide rates (b=0.46, SE=0.07, p<0.001), decreases in firearm suicides were not associated with off-setting increases in suicides by other methods (b=-0.04, SE=0.05, p=0.36). Furthermore, the absence of universal background check (b=0.12, SE=0.05, p=0.028) and mandatory waiting period (b=0.16, SE=0.06, p=0.008) laws was associated with a more steeply rising trajectory of statewide suicide rates. These results mitigate concerns regarding means substitution and speak to the potential high yield impact of systematically implemented means safety prevention efforts focused on firearms.

Abstract
Studies have documented a link between gun ownership and suicide, but little is known about characteristics of those most likely to use a gun in a suicide attempt rather than alternative methods. We examined which factors differentiate suicide decedents who died using a gun from those who died by other methods. We further examined whether such findings are consistent within the subcomponent of our larger sample comprised entirely of gun owning suicide decedents. Data reflect 267 suicide decedents, with data provided by individuals who identified as having lost someone to suicide (loss survivors). Within the full sample, a higher proportion of gun-owning and male suicide decedents died by firearm. Further, individuals who had previously discussed suicide or engaged in one or more non-lethal suicide attempts were less likely to die by suicide using a gun. Within the subsample of gun owning suicide decedents, a greater proportion of decedents who stored guns at home and in unsecure locations died from self-inflected gunshot wounds. These findings add clarity to the relationship between firearm ownership and death by suicide at the individual level. Furthermore, these findings are consistent with the notion that means safety implementation may represent a vital suicide prevention tool.

Abstract
The goal of this study was to describe the relative utility of the terms "means safety" versus "means restriction" in counseling individuals to limit their access to firearms in the context of a mock suicide risk assessment. Overall, 370 participants were randomized to read a vignette depicting a clinical scenario in which managing firearm ownership and access was discussed either using the term "means safety" or "means restriction." Participants rated the term "means safety" as significantly more acceptable and preferable than "means restriction." Participants randomized to the "means safety" condition reported greater intentions to adhere to clinicians' recommendations to limit access to a firearm for safety purposes (F[1,367] = 7.393, p = .007, [Formula: see text]). The term "means safety" may be more advantageous than "means restriction" when discussing firearm ownership and access in clinical settings and public health-oriented suicide prevention efforts.

Abstract
PURPOSE OF REVIEW Suicide is a major cause of mortality accounting for nearly 1 million deaths globally per year. Suicide occurs throughout the lifespan; therefore, large epidemiological samples are needed to identify patterns in suicide death. This review examines emerging evidence relating to risk and protective factors as well as preventive measures for suicide. RECENT FINDINGS The global financial crisis, natural disasters, air pollution and second-hand smoke have all been associated with increased suicide rates. At an individual level, past self-harm, parental loss or separation and younger age relative to classmates all confer risk. There is mixed evidence for religious affiliation and lithium levels in drinking water as protective factors. Means restriction strategies including barriers at suicide hotspots, firearms restrictions and limiting access to both pesticides and charcoal have all prevented suicide. Other interventions with recent evidence include improvements in mental health systems, selective serotonin reuptake inhibitor (SSRI) and lithium treatment in youth and mental health awareness in schools. SUMMARY The evidence for risk/protective factors for suicide continues to grow and, more importantly, numerous prevention efforts continue to demonstrate positive outcomes. Public policy experts should attend to the environmental and social determinants of health when devising suicide prevention programs, and the evidence-based prevention strategies identified here should be implemented more broadly.

Abstract
INTRODUCTION Non-fatal suicide attempts are a risk factor for suicide, but less is known about its effect on the method of injury used in an eventual suicide death. This study examines the association between history of non-fatal suicide attempt and the risk of a poisoning suicide versus firearm or hanging suicide in Colorado. METHODS Nine years (2004-2012, N=7,020) of suicide deaths in Colorado were compiled through the National Violent Death Reporting System. With these data, a retrospective cohort study was conducted in 2015, examining the risk associated with a history of suicide attempt and an eventual suicide death by poisoning versus a firearm or hanging suicide death. Multivariable log-binomial regression modeling was used to analyze the possible confounders of age and county type and gender as an effect modifier. RESULTS Suicide decedents with evidence of prior suicide attempt were twice as likely to eventually die by suicide via self-poisoning rather than by firearm injury (relative risk=1.94, 95% CI=1.8, 2.1, p<0.001). A significant interaction (p<0.001) between prior attempt and gender was identified and the relationship between prior attempt and method (poisoning versus firearm) was stronger among male than female suicides (female attempt history, 1.16, 95% CI=1.07, 1.27, p<0.001; male attempt history, 1.91, 95% CI=1.69, 2.16, p<0.001). CONCLUSIONS Individuals with a history of non-fatal suicide attempt are more likely to die by suicide via poisoning rather than firearm. Gender has a significant effect on this association. This information can be useful when discussing means restriction and suicide prevention efforts.
