A step forward in conceptualizing psychological closeness/distance to suicide methods: A qualitative approach

INTRODUCTION

Suicide is a leading cause of death, making suicide prevention a major public health priority. Increasing understanding of factors influencing suicidal behavior is paramount. Previous research has implicated psychological closeness, characterized by perceptions of how close/distant or attached/detached one feels to a particular object, as a cognitive factor that influences suicidal behavior. However, a better understanding of how psychological closeness to suicide methods is conceptualized by relevant populations is needed to improve its assessment and understand how it may confer risk for suicide.

METHODS

The goal was to refine the conceptualization of psychological closeness to suicide methods by incorporating feedback from relevant populations. We conducted 30 interviews with those primarily identifying as having lived experience of suicide (n = 10), clinicians who work with suicidal patients (n = 11), and suicide researchers (n = 9). A rigorous thematic approach using NVivo software was used to uncover common themes.

RESULTS

Primary themes included familiarity, comfort, and attachment, with one emerging theme of symbolism. We define these themes, provide context to their meaning, and share exemplary quotes across diverse participants.

CONCLUSION

We consider clinical, research, and policy implications from an interdisciplinary lens and discuss the strengths and limitations of this study.

Associations Between PTSD Features and Firearm Ownership and Storage: Results From the PRImary Care Screening Methods (PRISM) Study

INTRODUCTION

Veterans and active duty service members are significantly more likely to die by suicide using firearms compared to the general population. Not-secure firearm storage (e.g., keeping guns loaded/in an unlocked location) is associated with greater risk for suicide and a third of veteran firearm owners store at least 1 personal firearm unsecured. Veterans and active duty service members are also significantly more likely to be diagnosed with posttraumatic stress disorder (PTSD) than the general population. Symptoms of PTSD are divided into 4 criteria: reexperiencing, avoidance, negative affect, and hyperarousal. Research has suggested that endorsement of hyperarousal symptoms is positively associated with unsecure firearm storage and that avoidance symptoms might be negatively associated with unsecure storage practices. The present study examined the relationship between self-reported firearm ownership and storage practices among each item from the Primary Care PTSD Screening for DSM-IV-TR (PC-PTSD-IV) to explore associations between PTSD features and firearm ownership and storage.

MATERIALS AND METHODS

Participants were recruited from primary care clinics across 5 military installations in the United States as part of a larger study (Mage = 45.4, SD = 16.9). Among participants (n = 2,685), most of our sample identified as male (51.3%) and white (67.3%) with 61.6% currently serving in the military, 16.8% retirees, and 21.6% family members. PTSD symptoms were assessed using the PC-PTSD-IV and a quarter met the clinical threshold for PTSD. Binomial and multinomial logistic regression analyses were used.

RESULTS

Among completed responses, 989 (38.1%) people reported owning guns; among gun owners, 386 (39.0%) reported that they were loaded, and 352 (35.6%) reported they were loaded and unlocked. Endorsement of specific items on the PC-PTSD-IV, including those specific to hyperarousal and avoidance, was not significantly associated with storing firearms loaded and/or in nonsecure locations when controlling for military service. Non-responses to items around firearm storage practices were significantly associated with those individuals meeting the clinical threshold for PTSD according to the PC-PTSD-IV and participants currently serving had higher odds of storing at least 1 personal firearm loaded and both loaded and unlocked.

CONCLUSIONS

Results from our study highlight similarities and departures from the previous literature on the connection between PTSD and non-secure firearm storage practices. Further research may examine (1) the relation between PTSD symptoms and firearm storage between active duty service members, retirees, and family members and (2) whether non-response to items regarding firearm ownership is systematic.

Firearm storage practices among military veterans in the United States: Findings from a nationally representative survey

BACKGROUND

Unsafe storage of firearms is associated with increased risk of suicide.. However, contemporary population-based data on the prevalence and correlates of firearm storage practices among veterans are limited.

METHODS

Data were from the 2022 National Health and Resilience in Veterans Study, a nationally representative sample of 2441 veterans. Analyses examined: (1) the prevalence of firearm storage practices; (2) sociodemographic, psychiatric, and clinical characteristics associated with storing firearms loaded and/or in non-secure location; and (3) associations between types of potentially traumatic events and storage practices.

RESULTS

More than half of veterans reported owning one or more personal firearms (50.9%). Among firearm owners, 52.9% reported some form of unsafe firearm storage practice (i.e., loaded and/or non-secure location), with 39.9% reporting that they stored one or more firearms loaded. After adjusting for sociodemographic characteristics, major depressive, alcohol and drug use disorders, direct trauma exposures, future suicidal intent, and traumatic brain injury were associated with storing firearms loaded and/or in a non-secure location (ORs = 1.09-7.16). Veterans with a history of specific forms of direct trauma exposure (e.g., physical assault) were more likely to store firearms unsafely.

LIMITATIONS

Cross-sectional design precludes causal inference.

CONCLUSIONS

Half of U.S. veterans who own firearms store at least one personal firearm loaded and/or in a non-secure location, with approximately four-in-ten keeping a loaded firearm in the home. These high rates underscore the importance of nationwide training initiatives to promote safe firearm storage for all service members and veterans, regardless of risk status, as well as for healthcare professionals working with veterans.

Firearm carrying and adolescent suicide risk outcomes between 2015 and 2021 across nationally representative samples

INTRODUCTION

Firearms are the most frequent means of youth suicide for the 14-18-year-old age group, and adolescent firearm access confers substantial increases in the risk of suicidal behaviors. There have been significant increases in firearm purchases and firearm violence in the United States since the onset of the COVID-19 pandemic.

METHODS

This study uses four time points of nationally representative data from the Youth Risk Behavior Survey (YRBS) from 2015 to 2021 to examine the differential associations of reporting having carried a firearm and suicide-related outcomes, after controlling for relevant demographic factors. As a sensitivity analysis, we examined whether a similar risk pattern was seen for the probability of reporting depressed mood.

RESULTS

Results reveal significant increases in suicide-related outcomes among students who reported carrying a firearm and no significant increases among those who did not. Unlike the suicide-related outcomes, increases in depressed mood overtime were not limited to students who carried firearms, suggesting that the risk associated with firearms may be specific to suicide-related outcomes.

CONCLUSIONS

Carrying a firearm is associated with significant increases in the risk of suicidal ideation and behaviors among youth and this risk has increased between 2015 and 2021. Implications for youth suicide prevention and directions for future research are discussed.

Self-Reported Likelihood of a Future Suicide Attempt: The Role of Plans for Suicide

OBJECTIVE

The present study seeks to add to the existing literature by determining if having a plan for suicide, is associated with an individual's self-reported likelihood of attempting suicide in the future.

METHOD

Data came from a sample of 97 United States Army personnel with past week ideation or lifetime attempt history. Assessments were collected at baseline, 1-month, 3-month, and 6-months.

RESULTS

Self-reported likelihood of attempting suicide in the future was not associated with the presence of a plan for suicide overall or a plan with a specific method (i.e., firearm, cutting/scratching, and medication).

DISCUSSION

Although a plan for suicide is commonly thought to indicate elevated risk our findings suggest that presence or absence of suicide plans is not associated with more self-reported likelihood of a future suicide attempt.

Practical Capability Among Veterinarians: Preliminary Evidence of the Importance of Access to Lethal Medications in the Workplace

OBJECTIVE

Veterinarians die by suicide at elevated rates. Higher levels of capability for suicide among veterinarians, including access to lethal medications, may account for this discrepancy. This study aimed to determine the importance of accessibility of lethal medications in veterinary workplaces in the relationship between recent suicidal ideation and perceived likelihood of making a future suicide attempt.

METHOD

Participants identifying with one or more groups at high-risk for suicide (e.g., veterinarians, firearm owners) were recruited via social media to complete online self-report questionnaires examining demographic, work-related, and suicide-related risk factors. The sample of veterinarians (n = 310) was primarily female, White, and worked in small animal practices.

RESULTS

Method of lethal medication storage in the workplace moderated the relationship between past week ideation and perceived likelihood of a future suicide attempt such that the relationship became stronger among those storing medications unlocked during business hours and weaker among those storing medications locked during business hours.

CONCLUSION

Secure storage of lethal medications in the workplace may protect against suicide risk. Barriers to lethal medications, when not actively in use, may reduce both physical and cognitive accessibility. Future research should determine the impact of workplace lethal medication storage on suicidal behavior among veterinarians.HIGHLIGHTSLethal med storage moderates link between suicidal thoughts and belief suicide is likelyStoring unlocked may increase physical and cognitive accessibility of this methodWorking with vets to develop and implement means safety strategies will be important.

Determining who healthcare providers screen for firearm access in the United States

Healthcare providers are well positioned to screen for firearm access to reduce risk of suicides, yet there is a limited understanding of how often and for whom firearm access screening occurs. The present study examined the extent to which providers screen for firearm access and sought to identify who has been screened in the past. The representative sample included 3510 residents from five US states who reported whether they have been asked about their access to firearms by a healthcare provider. The findings demonstrate that most participants have never been asked by a provider about firearm access. People who have been asked were more likely to be White, male, and firearm owners. Those with children under 17 years old in the home, that have been in mental health treatment, and report a history of suicidal ideation were more likely to be screened for firearm access. Although there are interventions for mitigating firearm related risks in healthcare settings, many providers may be missing the opportunity to implement these because they do not ask about firearm access.

A Standard Protocol for the Clinical Management of Suicidal Thoughts and Behavior: Implications for the Suicide Prevention Narrative

The last several decades have witnessed growing and converging evidence from randomized controlled trials (RCT's) that an identifiable set of simple clinical management strategies are effective for those at risk for suicidal thinking and/or suicide attempts. The current article offers a brief review of clinical strategies supported by RCT's targeting suicidality as "commonalities of treatments that work" and related recommendations for use in the delivery of care for suicidal individuals in generic fashion, regardless of any particular treatment, theoretical orientation, or intervention perspective. The article includes eight recommendations that can be easily adapted across the full range of clinical contexts, institutional settings, and delivery systems, recommendations that help frame a broader clinical narrative for suicide prevention. Recommendations cut across five identifiable domains or clinical strategies for the delivery of care: (1) informed consent discussion that identifies risks of opting out of care and emphasizes the importance of shared responsibility and a collaborative process, (2) an explanatory model that emphasizes the importance of individual self-management skills and targeting the causes of suicide rather than describing suicidality as a function of mental illness, (3) the importance of proactively identifying barriers to care and engaging in targeted problem-solving to facilitate treatment adherence, (4) a proactive and specific plan for management of future suicidal episodes, and (5) reinforcing the importance of taking steps to safeguard lethal means and facilitate safe storage of firearms.

Adolescent suicide attempts in the United States: When suicide ideation and suicide capability interact

INTRODUCTION

Guided by the interpersonal theory of suicide, this study examined whether the relationship between level of suicide ideation and attempted suicide varies as a function of suicide capability.

METHODS

Cross-sectional data were obtained from the 2017 and 2019 Youth Risk Behavior Survey in which 28,442 respondents were sampled. Confirmatory factor analysis was conducted to create a latent suicide capability variable. Structural equation modeling was used to test the moderating effects of suicide capability on the relationship between level of suicide ideation and attempted suicide, adjusting for sociodemographic characteristics, sadness/hopelessness, and the sampling design.

RESULTS

Compared to adolescent with no reported ideation, those reporting single and dual ideation experienced increased odds of attempted suicide. The relationship between level of suicide ideation and attempted suicide significantly varied as a function of capability. While adolescents with dual suicide ideation experienced higher rates of attempted suicide at increasing levels of capability, faster rates of change of attempted suicide at increasing levels of capability were observed among those with single and no reported ideation.

CONCLUSION

Capability may heighten the risk of suicide attempts among youth, suggesting that treatment efforts could be directed at reducing exposure to painful and provocative experiences associated with suicide behaviors.

Determining subgroups that exist among US firearm owners

OBJECTIVE

To identify and verify classes of firearm owners that exist within the United States and determine the sources that classes deemed credible to discuss firearm safety for suicide prevention.

METHODS

The study is composed of two parts. Part 1 (N = 1018) utilizes a nationally representative sample of firearm owners. Part 2 (N = 1064) consists of firearm owners from Mississippi, Minnesota, and New Jersey.

RESULTS

Four unique classes were identified in Sample 1: multiple firearms class, single handgun class, few firearms class, and long-gun class. A three-class solution was found for sample 2. Two of the classes from sample 1 replicated: multiple firearms class and single handgun class. Although many of the classes differed in the ranking of credible sources, a combination of The American Foundation for Suicide Prevention, law enforcement officers, and family members was ranked as credible sources among all classes.

CONCLUSIONS

Findings provide evidence of the heterogenous nature of firearm owners and can be utilized to better understand the subgroups of firearm owners. Additionally, the findings from the credible sources analyses can be leveraged to create more effective safe firearm storage messaging which may increase adherence with safe storage suggestions and ultimately reduce suicide rates.

Growing together: interpersonal predictors of posttraumatic growth trajectory among suicide-loss survivors

BACKGROUND

Recent studies have indicated that grieving after suicide loss can be particularly complex and traumatic. However, studies have recognized the opportunity for personal growth among suicide-loss survivors. This study signifies an effort to develop a comprehensive understanding of the underlying interpersonal facilitators of posttraumatic growth (PTG) among suicide-loss survivors in a longitudinal design.

METHOD

Participants included 189 suicide-loss survivors (155 females), aged 21-73, who completed questionnaires of thwarted belongingness (TB), perceived burdensomeness (PB), and self-disclosure at T1. Moreover, participants were assessed on PTG levels at T1, 18 months (T2), and 42 months (T3).

RESULTS

The integrated mediation model indicated that both TB and PB contributed to the PTG trajectory. PB and self-disclosure contributed to PTG at T3 beyond the PTG trajectory across time. We also found self-disclosure to mediate the association of TB and PTG at T2 and T3.

CONCLUSIONS

These findings suggest that interpersonal factors play critical roles in contributing to PTG over time among suicide-loss survivors. Basic psychoeducational interventions designed to foster interpersonal behaviors may facilitate achieving PTG among survivors in the aftermath of suicide loss.

Rates of Preparatory Suicidal Behaviors across Subgroups of Protective Firearm Owners

Firearm availability is correlated with increased suicide mortality. Some firearm owners may be more vulnerable to suicide than others, but heterogeneity among firearm owners has received little empirical attention. The present study used latent class analysis (LCA) to identify subgroups of firearm owners who keep firearms primarily for protection (i.e., protective firearm owners) in a national sample of 2311 U.S. adult firearm owners. Self-protection was the primary motive for firearm ownership for 1135 (49.1%) participants. Results of the LCA identified three latent classes that differed with respect to secondary reasons for firearm ownership, number and types of firearms owned, firearm ownership history, and demographics. The smallest latent class (n = 26, 2.3% of protective firearm owners), which owned a high volume of firearms and had high levels of early childhood exposure to firearms, reported significantly higher rates of lifetime preparatory suicidal behaviors. Results suggest that firearm owners are a heterogeneous population, with some subgroups being more vulnerable to suicide than others.

A high-need, high-impact educational session on firearms and death by suicide

BACKGROUND

The suicide rate among Veterans is 1.5 times greater than that for civilians, partly a result of the high use of firearms as the means for suicide. One effective strategy to reduce Veteran suicide by firearms is to provide counseling on firearm safety as a method of means reduction. However, many clinicians do not discuss firearm safety with Veterans.

AIMS

This study evaluates a one-hour educational seminar for clinicians on lethal means safety.

MATERIALS AND METHODS

One hundred and ninety clinicians from the Veterans Health Administration, including social workers, psychologists, psychiatrists, and nurses, participated in the training. The seminar was streamed during the South Central Mental Health Illness Research, Education and Clinical Center's Community-Based Outpatient Clinic Mental Health Grand Rounds, for which participants were eligible for continuing education units. Data were collected immediately after the training and four months later.

RESULTS

After completing the training, participants believed that it was important to speak with Veterans about firearm safety and felt knowledgeable and empowered to do so. Four months after the seminar, participants had counseled, on average, over half of Veterans treated about lethal means safety.

DISCUSSION

Participants reported the value of normalizing discussions about firearm safety with their Veterans and focusing on the safety aspect while discussing firearms.

CONCLUSIONS

This webinar was effective in providing clinicians the skills to talk with Veterans about firearm safety and continued to impact their practice four months after training. The training is available for free on our website at https://www.mirecc.va.gov/visn16/public-health-approach-to-firearms-and-death-by-suicide.asp.

A multi-state evaluation of the association between mental health and firearm storage practices

Firearm storage method is a potentially modifiable risk factor for suicide. Using data from a large, multi-state survey, we sought to determine whether there is an association between mental health and household firearm storage practices, and characterize that association by state of residence. Participants who endorsed the presence of a household firearm and answered the mental health questions in the 2016-2017 Behavioral Risk Factor Surveillance System from eight states were included (n=26,949). Exposures were recent poor mental health (≥14 vs. 0-13 days/past month), and diagnosis of depression. Outcomes were household firearm storage practices (loaded, and both loaded and unlocked). Using Poisson regression, we calculated adjusted prevalence ratios (aPR) overall and stratified by state of residence. Of adults endorsing a household firearm, 35.1% reported storing a firearm loaded, and of those, 53.4% reported that the firearm was both loaded and unlocked. Neither recent poor mental health nor depression was associated with loaded (aPR 1.14 [95% CI: 0.95-1.37] and aPR 0.94 [95% CI 0.80-1.09], respectively) or loaded and unlocked (aPR 1.08 [95% CI 0.88-1.42] and aPR 1.04 [95% CI 0.88-1.22], respectively) firearm storage. In the setting of highly prevalent loaded firearm storage, no differences in storage practices by mental health indicators were observed across eight states despite disparate firearm policies and local culture. The lack of difference in storage practices by mental health indicators across several states highlights an opportunity to improve means safety counseling practices, and the need for dedicated evaluation of state-level firearm storage policies.

Exploring the scope and structure of suicide capability

OBJECTIVE

Recent theories of suicide suggest that a construct called "capability for suicide" facilitates the progression from suicidal thoughts to attempts. Various measures of capability have been developed to assess different parts of the construct, but studies report inconsistent findings regarding reliability, validity, and structure. The present study pooled items from multiple measures to identify distinct, reliable, and valid domains of suicide capability.

METHOD

We administered items from several suicide capability measures to an online sample of US adults (n = 387), and utilized exploratory factor analysis to identify distinct domains of capability. We then examined the internal consistencies of and intercorrelations among these domains, as well as their associations with suicide attempts.

RESULTS

Findings identified three domains of suicide capability: fearlessness about death, practical capability, and pain tolerance. These domains were internally consistent (αs = 0.80-0.92), and relatively independent from one another (intercorrelations = 0.15-0.35). Finally, each of these domains was moderately elevated among attempters compared to ideators (although only fearlessness about death and practical capability offered unique information about attempter status).

CONCLUSIONS

Findings suggest that fearlessness about death, practical capability, and pain tolerance can be measured reliably, and may be relevant for understanding which ideators make attempts.

Suicide risk and firearm ownership and storage behavior in a large military sample

Firearms account for the majority of suicide deaths in the United States military and access to firearms is a risk factor for suicide. Prior research has shown service members tend to store firearms unsafely, with some research indicating this is particularly true among those with elevated suicide risk. Existing research has focused on individuals at known risk for suicide; however, those who die by suicide using a firearm are prone to avoiding mental healthcare and underreporting suicidal ideation, thereby necessitating an understanding of this phenomenon among firearm owners outside of the mental healthcare system. The present study examined firearm storage and suicide risk in a large nonclinical sample of service members (total sample n = 953; firearm owning sample = 473). Lifetime suicidal ideation, current depressive symptoms, and perceived likelihood of making a future suicide attempt were associated with unsafe firearm storage. In contrast, lifetime suicidal ideation was not associated with a greater likelihood to own firearms. These findings suggest those at risk of suicide are more likely to store firearms unsafely, which increases ease of access to firearms. These findings reiterate the importance of means safety as a suicide prevention strategy.

Use of the acquired capability for suicide scale (ACSS) among United States military and Veteran samples: A systematic review

BACKGROUND

Military personnel and Veterans are at increased risk for suicide. Theoretical and conceptual arguments have suggested that elevated levels of acquired capability (AC) could be an explanatory factor accounting for this increased risk. However, empirical research utilizing the Acquired Capability for Suicide Scale (ACSS) in military populations has yielded mixed findings.

METHODS

To better ascertain what factors are associated with AC, and whether methodological limitations may be contributing to mixed findings, a systematic review was conducted.

RESULTS

A total of 31 articles utilized the ACSS to examine factors associated with AC, including combat history, in United States (U.S.) military personnel and Veterans. Nearly all studies (96.8%) were rated high risk of bias. Use of the ACSS varied, with seven different iterations utilized. Nearly all studies examined correlations between the ACSS and sample characteristics, mental health and clinical factors, Interpersonal Theory of Suicide constructs, and/or suicide-specific variables. Results of higher-level analyses, dominated by cross-sectional designs, often contradicted correlational findings, with inconsistent findings across studies.

LIMITATIONS

Included studies were non-representative of all U.S. military and Veteran populations and may only generalize to these populations.

CONCLUSIONS

Due to the high risk of bias, inconsistent use of the ACSS, lack of sample heterogeneity, and variability in factors examined, interpretation of current ACSS empirical data is cautioned. Suggestions for future research, contextualized by these limitations, are discussed.

Firearm Ownership and Capability for Suicide in Post-Deployment National Guard Service Members

OBJECTIVE

National Guard service members demonstrate increased suicide risk relative to the civilian population. One potential mechanism for this increased risk may be familiarity with and access to firearms following deployment. This study examined the association between firearm ownership, reasons for ownership, and firearm familiarity with a widely studied suicide risk factor-capability for suicide-among National Guard service members.

METHOD

Data were drawn from a cross-sectional survey of National Guard service members conducted immediately post-deployment in 2010. Service members (n = 2,292) completed measures of firearm ownership, firearm familiarity, and capability for suicide.

RESULTS

Firearm ownership and increased firearm familiarity were associated with capability for suicide (d = 0.47 and r = .25, for firearm ownership and familiarity, respectively). When examined separately based on reason for ownership, owning a firearm for self-protection (d = 0.33) or owning a military weapon (d = 0.27) remained significantly associated with capability for suicide. In contrast, owning a firearm for hobby purposes did not (d = -0.07).

CONCLUSION

Our findings support theories emphasizing practical aspects of suicide (e.g., three-step theory) and suggest that owning firearms, in particular for self-protection, along with familiarity using firearms may be associated with greater capability for suicide.

Correlates of Intimate Partner Homicide among Male Suicide Decedents with Known Intimate Partner Problems

OBJECTIVE

Intimate partner (IP) problems are risk factors for suicide among men. However, there is little understanding of why some male suicide decedents who had such problems killed their partners before death (i.e., "IP homicide-suicide"), while most of these decedents did not. To inform prevention efforts, this study identified correlates of IP homicide among male suicide decedents with known IP problems.

METHODS

We examined IP homicide correlates among male suicide decedents aged 18+ years who had known IP problems using 2003-2015 National Violent Death Reporting System data. Prevalence odds ratios and 95% confidence intervals were estimated for demographic, incident, and circumstance variables. IP homicide-suicide narratives were examined to identify additional prevention opportunities.

RESULTS

An estimated 1,504 (5.0%) of 30,259 male suicide decedents who had IP problems killed their partner. IP homicide-suicide perpetration was positively correlated with suicide by firearm and precipitating civil legal problems but negatively correlated with mental health/substance abuse treatment. An estimated 33.7% of IP homicide-suicides occurred during a breakup; 21.9% of IP homicide-suicide perpetrators had domestic violence histories.

CONCLUSIONS

Connections between the criminal justice and mental health systems as well as stronger enforcement of laws prohibiting firearm possession among domestic violence offenders may prevent IP homicide-suicides.

Political Beliefs, Region of Residence, and Openness to Firearm Means Safety Measures to Prevent Suicide

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.

What I have is what I am: Differences in demographics, suicidal thoughts and behaviors, and firearm behavior and beliefs between firearm owners who do and do not primarily identify as firearm owners

Non-legislative forms of means safety (i.e., safe firearm storage practices) have been promoted as a way to reduce elevated suicide risk found among firearm owners. However, evidence suggests that some firearm owners are less willing than others to engage in these practices. The current study aimed to understand factors that differentiate firearm owners' beliefs and behaviors that are relevant to suicide risk by examining differences between individuals for whom firearm ownership represents a central aspect of identity (i.e., primary firearm owners) versus firearm owners who primarily identify with some other demographic or occupational characteristic. Results of main analyses revealed that primary firearm owners were more likely to be male, were less likely to have experienced suicidal ideation, were less likely to store their firearms safely across a number of storage methods, and were less open to means safety across all storage methods. These findings highlight demographically which firearm owners may be more likely to view firearm ownership as central to their identity and also suggest that this identification may be associated with beliefs and behaviors that increase suicide risk. Future firearm suicide prevention efforts should focus on culturally competent discussions and messaging to find common ground with firearm owners and to increase the salience of suicide among firearm owners.

Firearm Ownership, Means Safety, and Suicidality

OBJECTIVE

Means safety interventions are effective at reducing suicide rates. This study examined beliefs about firearm ownership or storage and suicide risk, lifetime suicidal thoughts, and openness to means safety.

METHOD

A community sample of 107 American adult firearm owners (51.4% male; 82.2% White; _m age = 37.46) completed a series of self-report questionnaires via Amazon's Mechanical Turk.

RESULTS

Hierarchical linear regressions indicated that beliefs regarding firearm ownership or storage were associated with openness to means safety measures to prevent a suicide attempt by someone else, but not to prevent one's own suicide attempt. Additionally, results from analyses of covariance indicated that firearm owners with lifetime ideation had stronger beliefs regarding the association between firearm ownership or storage and suicide risk.

CONCLUSIONS

Findings indicate firearm owners' willingness to engage in means safety may be influenced by the degree to which they believe firearm storage is associated with suicide. Furthermore, firearm owners with prior suicide ideation are more open to the idea that firearm ownership and storage are related to suicide risk. Viewing suicide as salient to one's own life may serve as a focal point in efforts to increase openness to means safety among firearm owners.

Association of Firearm Ownership, Use, Accessibility, and Storage Practices With Suicide Risk Among US Army Soldiers

Importance

Since 2004, the suicide rate among US Army soldiers has exceeded the rate of death from combat injury. It is critical to establish factors that increase the risk of acting on suicidal thoughts to guide early intervention and suicide prevention.

Objective

To assess whether firearm ownership, use, storage practices, and accessibility are associated with increased risk of suicide.

Design, Setting, and Participants

In this case-control study, suicide cases (n = 135) were defined as US Army soldiers who died by suicide while on active duty between August 1, 2011, and November 1, 2013. Next-of-kin and Army supervisors of soldiers who died by suicide (n = 168) were compared with propensity-matched controls (n = 137); those soldiers with a suicidal ideation in the past year (n = 118) provided structured interview data. Data were analyzed from April 5, 2018, to April 2, 2019.

Main Outcomes and Measures

Firearm ownership, storage, and accessibility were assessed by using items from the World Health Organization Composite International Diagnostic Interview screening scales along with items created for the purpose of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) study.

Results

Among the 135 suicide decedents, next-of-kin reported that they had greater accessibility to firearms compared with propensity-matched controls. Specifically, suicide decedents were more likely to own 1 or more handguns compared with propensity-matched controls (odds ratio [OR], 1.9; 95% CI, 1.0-3.7; χ21 = 4.2; false discovery rate [FDR] P = .08), store a loaded gun at home (OR, 4.1; 95% CI, 1.9-9.1; χ21 = 12.2; FDR P = .003), and publicly carry a gun when not required for military duty (OR, 3.2; 95% CI, 1.4-7.3; χ21 = 7.4; FDR P = .02). The combination of these 3 items was associated with a 3-fold increase in the odds of suicide death (OR, 3.4; 95% CI, 1.2-9.4; χ21 = 5.4; FDR P = .05). Storing a loaded gun with ammunition at home or publicly carrying a gun when not on duty was associated with a 4-fold increase in the odds of suicide death (OR, 3.9; 95% CI, 1.9-7.9; χ21 = 14.1; FDR P = .002).

Conclusions and Relevance

In this study, in addition to gun ownership, ease and immediacy of firearm access were associated with increased suicide risk. Discussion with family members and supervisors about limiting firearm accessibility should be evaluated for potential intervention.

Deadly Experience: The Association Between Firing a Gun and Various Aspects of Suicide Risk

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.

Firearm storage and shooting experience: Factors relevant to the practical capability for suicide

The capability for suicide is posited to facilitate the relatively rare transition from suicidal ideation to suicidal behavior, although the operational definition of the construct continues to evolve. The Three Step Theory proposes that capability is multifaceted and includes practical capability for suicide, defined as comfort with and access to lethal means. Empirical examinations of this construct are thus far limited. Two previous studies have examined the association between firearm storage and shooting experience and common measures of capability for suicide. This study expands the generalizability of previous findings by investigating the relationship between capability for suicide, firearm storage practices, and experience shooting a firearm in a sample of 300 American firearm owners. We found that individuals who store their firearms unsafely (loaded, in a non-secure location, or without a locking device) and who have greater experience shooting firearms have significantly higher capability for suicide. These findings extend the evidence for the construct of practical capability as it relates to firearms and highlight the need for firearm-specific means safety measures to prevent suicide.

Investigating the Relationship Between Social and Economic Policy Views, Firearm Ownership, and Death by Firearm in a Sample of Suicide Decedents

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.

The Association Between Gun Ownership and Statewide Overall Suicide Rates

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.

Military personnel compared to multiple suicide attempters: Interpersonal theory of suicide constructs

The current study aimed to address the discrepancy between suicide rates in the military and general population by comparing facets of the interpersonal theory of suicide between civilians with multiple suicide attempts and U.S. military personnel. Military personnel exhibited higher levels of capability for suicide but lower levels of perceived burdensomeness and thwarted belongingness than civilian multiple attempters. When comparing only personnel endorsing ideation and civilian multiple attempters, the significant difference for capability remained, but the differences for perceived burdensomeness and thwarted belongingness became nonsignificant. Results suggest the emergence of ideation places personnel at a greater risk for suicide than many civilian multiple attempters.

Perceptions of firearms and suicide: The role of misinformation in storage practices and openness to means safety measures

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.

Practical capability: The impact of handgun ownership among suicide attempt survivors

Suicide is a leading cause of death and represents a serious public health concern. However, our ability to predict its occurrence has not improved over the last 50 years and we continue to rely on past suicidal behavior as the most robust predictor of future suicidal behavior. Recent theories have emphasized the role of contextual factors that increase capability to act on suicidal thoughts, including access to and familiarity with lethal means. We sought to examine the impact of handgun ownership, a component of practical capability as defined by the Three-Step Theory, on the relationship between past week suicidal ideation and perceived likelihood of making a future suicide attempt within a community sample of previous suicide attempters. Results indicate that, among suicide attempt survivors who are currently suicidal, handgun ownership increases the likelihood of predicting engagement in future suicidal behavior. As self-reported predictions about suicidal behavior have been found to be uniquely predictive of actual suicidal behavior, handgun ownership may facilitate the transition from ideation to action. The relevance of these findings to means safety strategies is discussed.

Posttraumatic Stress Disorder Symptom Clusters and the Interpersonal Theory of Suicide in a Large Military Sample

Prior studies examining posttraumatic stress disorder (PTSD) symptom clusters and the components of the interpersonal theory of suicide (ITS) have yielded mixed results, likely stemming in part from the use of divergent samples and measurement techniques. This study aimed to expand on these findings by utilizing a large military sample, gold standard ITS measures, and multiple PTSD factor structures. Utilizing a sample of 935 military personnel, hierarchical multiple regression analyses were used to test the association between PTSD symptom clusters and the ITS variables. Additionally, we tested for indirect effects of PTSD symptom clusters on suicidal ideation through thwarted belongingness, conditional on levels of perceived burdensomeness. Results indicated that numbing symptoms are positively associated with both perceived burdensomeness and thwarted belongingness and hyperarousal symptoms (dysphoric arousal in the 5-factor model) are positively associated with thwarted belongingness. Results also indicated that hyperarousal symptoms (anxious arousal in the 5-factor model) were positively associated with fearlessness about death. The positive association between PTSD symptom clusters and suicidal ideation was inconsistent and modest, with mixed support for the ITS model. Overall, these results provide further clarity regarding the association between specific PTSD symptom clusters and suicide risk factors.

Firearm suicide: pathways to risk and methods of prevention

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.

From ideation to action: recent advances in understanding suicide capability

Suicide capability is one of few risk factors associated with suicide attempts among ideators. In the decade since the Interpersonal Psychological Theory of Suicide introduced the concept of acquired capability (i.e. the ability to face the fear and pain associated with death), understanding of the capability to attempt suicide has grown. Acquired (e.g. NSSI), dispositional (e.g. genetic), and practical contributors (e.g. access to firearms) appear to influence suicide capability via mechanisms such as the fear of death, persistence through pain, and familiarity with suicide methods. Self-report methods have shown mixed results, highlighting the importance of developing behavioral measures of suicide capability.

Rising longitudinal trajectories in suicide rates: The role of firearm suicide rates and firearm legislation

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.

Differentiating suicide decedents who died using firearms from those who died using other methods

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.

Handgun Legislation and Changes in Statewide Overall Suicide Rates

OBJECTIVES

To examine the extent to which 4 laws regulating handgun ownership were associated with statewide suicide rate changes.

METHODS

To test between-group differences in statewide suicide rate changes between 2013 and 2014 in all 50 states and the District of Columbia with and without specific laws, we ran analyses of covariance.

RESULTS

We found significant differences in suicide rate changes from 2013 to 2014 in states with mandatory waiting periods and universal background checks relative to states without such laws. States with both laws differed significantly from those with neither. No significant differences in rate changes were noted for open carry restrictions or gun lock requirements.

CONCLUSIONS

Some state laws regulating aspects of handgun acquisition may be associated with lower statewide suicide rates. Laws regulating handgun storage and carrying practices may have a smaller effect, highlighting that legislation is likely most useful when its focus is on preventing gun ownership rather than regulating use and storage of guns already acquired. Public Health Implications. The findings add to the increasing evidence in support of a public health approach to the prevention of suicide via firearms, focusing on waiting periods and background checks.

Thinking or doing? An examination of well-established suicide correlates within the ideation-to-action framework

Limited research has examined differences in well-established suicide correlates between individuals with various histories of suicidality within the ideation to action framework. We hypothesized that individuals without a history of elevated suicidality would exhibit lowest levels of suicide correlates (perceived burdensomeness, thwarted belongingness, emotion dysregulation, depressive symptoms), and group differences would not be present between those with a history of suicidal ideation relative to those with a history of suicide attempts on variables not theorized to contribute to the capability for suicide. Lastly, we hypothesized that those with a prior history of suicide attempt(s) would exhibit higher levels of lifetime painful and provocative events and fearlessness about death relative to those with a history of ideation only. A community sample of adults (N=378) recruited in part on the basis of a history of suicidality completed self-report questionnaires online. The results were largely consistent with our hypotheses. However, there were no differences in fearlessness about death between those with a history of suicidal ideation and those with a history of attempts. Many variables considered robust correlates of suicide may only directly relate to suicidal ideation rather than suicide attempts, thereby limiting their utility in understanding the transition from ideation to action.

Recent Advances in Means Safety as a Suicide Prevention Strategy

Despite advances in theory and the development and implementation of evidence-based treatments, the United States suicide rate has been rising continuously for over a decade. Although this does not indicate that traditional treatment approaches should be abandoned, it does highlight the need to supplement such approaches with alternatives. One seemingly highly valuable option is means safety, defined as the reduced access to and/or increased safe storage of potentially lethal methods for suicide. This paper provides a review of the current literature on the prevalence of six methods for suicide and preventative efforts aimed to reduce suicide rates. The majority of means safety interventions seem promising given that these methods are common and highly lethal. However, cultural and practical barriers will need to be taken into consideration when implementing these plans. Overall, means safety efforts and preventative measures seem to be promising ways to reduce the national suicide rate if implemented.
