Handgun Legislation and Changes in Statewide Overall Suicide Rates

Toward a Public Health Approach to Farmer Suicide Prevention: The Potential Power of Systems Change

OBJECTIVE

Suicide among farmers has, over the past 20 years, garnered attention from scholars around the world. The purpose of this paper is twofold. First, this paper will present a framework for considering farmer suicide that builds upon the Interpersonal-Psychological Theory of Suicidal Behavior and extends our current explanations of suicide to include a multilevel, multifactorial focus on individual, interpersonal, community and systemic factors at the root of stressors contributing to suicide among farmers. Secondly, a blueprint for farmer suicide prevention, leveraging the Water of Systems Change Model, is proposed.

METHOD

In the spirit of conveying multi-layered influence on farmer suicide while highlighting relevant levels for prevention a parsimonious, prevention-based model of farmer suicide is presented.

RESULTS

The Water of Systems Change (WSC) model incorporates research to bring attention to the community, organizational, and societal conditions that keep a problem, such as farmer suicide, from being eradicated.

CONCLUSION

Suicide is a societal issue that requires a multi-level response. Farmer suicide is a particular concern, as farmers provide for and support all of us. It is incumbent upon public health and the community-at-large to improve our policies, systems, and contexts to create an environment in which farmers are also provided for and supported.

State Gun Regulations and Reduced Gun Ownership are Associated with Fewer Firearm-Related Suicides Among Both Juveniles and Adults in the USA

BACKGROUND

Few studies have investigated the relationship between specific gun regulations and gun ownership with the firearm-related suicide rate among juveniles and adults across U.S. states. Therefore, this study seeks to determine if gun ownership rates and gun restrictions are related to the firearm-related suicide rate in both the pediatric and adult populations.

METHODS

Fourteen measures of state gun law restrictions and gun ownership were collected. These included Giffords Center ranking, gun ownership percentages, and 12 specific firearm laws. Unadjusted linear regressions modeled the relationship between each individual variable and the rate of firearm-related suicides for adults and children across states. This was repeated using a multivariable linear regression adjusting for poverty, poor mental health, race, gun ownership, and divorce rates by state. P values of <0.004 were considered significant.

RESULTS

In the unadjusted linear regression, 9 of 14 firearm-related measures were statistically associated with fewer firearm-related suicides in adults. Similarly, 9 of 14 measures were found to be associated with fewer firearm-related suicides in the pediatric population. In the multivariable regression, 6 of 14 vs. 5 of 14 measures were statistically associated with fewer firearm-related suicides in the adult and pediatric populations, respectively.

CONCLUSIONS

Ultimately, this study found that increased state gun restrictions and lower gun ownership rates were associated with fewer firearm related suicides among juveniles and adults in the US. This paper provides objective data to help lawmakers as they create gun control legislation that can potentially decrease the rate of fire-arm related suicide.

Firearm Violence in the United States: An Issue of the Highest Moral Order

Firearm violence in the United States produces over 36,000 deaths and 74,000 sustained firearm-related injuries yearly. The paper describes the burden of firearm violence with emphasis on the disproportionate burden on children, racial/ethnic minorities, women and the healthcare system. Second, this paper identifies factors that could mitigate the burden of firearm violence by applying a blend of key ethical theories to support population level interventions and recommendations that may restrict individual rights. Such recommendations can further support targeted research to inform and implement interventions, policies and laws related to firearm access and use, in order to significantly reduce the burden of firearm violence on individuals, health care systems, vulnerable populations and society-at-large. By incorporating a blended public health ethics to address firearm violence, we propose a balance between societal obligations and individual rights and privileges.

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.

What is "safety"?: Lethal means counseling as a cross-cultural communication

U.S. suicide rates have risen every year over the past two decades with self-directed firearm use as the method accounting for the highest proportion of deaths. This pattern is particularly pronounced among veterans and members of the U.S. Armed Forces. The numerical burden of firearm-related suicide accompanied by characteristics of self-directed firearm injury have motivated the development of lethal means safety initiatives focused on firearms. Simultaneously, research has sought to characterize patterns of firearm ownership and use among veterans as well as optimal strategies for clinicians to deliver suicide prevention messages to firearm owners. Increasingly, findings from research have been understood as cultural factors that warrant greater attention to improve the quality of lethal means counseling. Here, we review and interpret selected research on cultural aspects of firearm ownership and suggest that cultural differences between health care practitioners and firearm owners may result in health care practitioners delivering clinical interventions that are broadly divergent from perspectives within the cultural frameworks of firearm owners. We follow by organizing these cultural factors into existing frameworks of cultural competency training as a basis for developing curriculum for health care practitioners to improve clinical care.

Considerations in the assessment of help-seeking and mental health service use in suicide prevention research

OBJECTIVE

The connection of individuals at elevated suicide risk to mental healthcare services represents a critical component of suicide prevention efforts. This article provides recommendations for enhancing the assessment of help-seeking and mental health service use within the context of suicide prevention research.

METHOD

We discuss evidence-based and theoretical rationale for improving current approaches to assessing help-seeking and mental health service use among at-risk individuals.

RESULTS

Recommendations are offered within three domains: (a) consideration of the spectrum of connection to care, (b) assessment of the degree to which mental healthcare services seek to and effectively target suicidal symptoms, and (c) evaluation of the sources and types of treatment and care sought and received by at-risk individuals.

CONCLUSIONS

To further our understanding of how to bolster connection to care and improve experiences with mental healthcare services among individuals at elevated suicide risk, it is imperative that stakeholders precisely capture the degree, efficacy/effectiveness, and nature of care sought and received by individuals. In so doing, research gaps might be better identified and, ultimately, mental healthcare services might be better leveraged as tools to prevent suicide and support individuals in creating lives they perceive to be worth living.

Increasing Rate of Unintentional Firearm Deaths in Youngest Americans: Firearm Prevalence and Covid-19 Pandemic Implication

BACKGROUND

The United States has had, by far, the world's greatest civilian ownership of firearms. An even greater ownership occurred during the Covd-19 pandemic, mostly of handguns and including many new owners. The U.S. has also had the least progress of the 41 highest sociodemographic countries ranked by the Institute for Health Metrics and Evaluation in reducing the unintentional firearm mortality rate in young children. This study characterized the unintentional firearm mortality trends in American 1-4 year-olds by sex and race/ethnicity and evaluated the trends in the context of firearm prevalence in the U.S.

METHODS

Mortality data for 1999-2018 were obtained from the U.S. Centers for Disease Control and Prevention and the Institute for Health Metrics and Evaluation, firearm injury and mortality data for 2016-2020 from Everytown for Gun Safety #NotAnAccident database, firearm background check data for 1999-2020 from the National Instant Criminal Background Check System, and civilian firearm prevalence for 2017 from the Small Arms Survey.

RESULTS

In American 1-4 year-olds, the rate of unintentional firearm deaths during 1999-2018 increased exponentially at an average annual percent rate of 4.9 (p < 0.001) and was greatest in non-Hispanic black children. Unintentional firearm deaths had the most rapid increase of all evaluable causes of death in the age group. The unintentional firearm death rate increase was correlated with the concurrent rate of firearm background checks and handgun permits issued (each p < 0.001) and in non-Hispanic white children with handgun prevalence in their families (p = 0.03). Globally, the unintentional firearm death rate was also correlated with firearm prevalence (p = 0.02).

CONCLUSIONS

An increase in fatal firearm accidents in the United States death rate among 1-4 year-olds is directly associated with the steadily increasing prevalence of firearms. The acceleration of firearm deaths and injuries among young Americans, especially among non-Hispanic black children, requires urgent solutions to address firearm prevalence and access. The problem is expected to become even more urgent as a result of the record high firearm sales that occurred in the United States during the 2020 coronavirus pandemic.

Comorbidity Profiles Identified in Older Primary Care Patients Who Attempt Suicide

OBJECTIVES

To identify comorbidity profiles of older patients last seen in primary care before a suicide attempt and assess attempt and clinical factors (eg, means and lethality of attempt) associated with these profiles.

DESIGN

Cohort study and latent class analysis using Department of Veterans Affairs (VA) national data (2012-2014).

SETTING

All VA medical centers in the United States.

PARTICIPANTS

A total of 2131 patients 65 years and older who were last seen by a primary care provider before a first documented suicide attempt.

MEASUREMENTS

Fatal suicide attempt and means were identified using the National Suicide Data Repository. Nonfatal attempt was defined using the National Suicide Prevention Applications Network. Medical and psychiatric diagnoses and other variables were determined from electronic medical records.

RESULTS

Patients (mean age = 74.4 y; 98.2% male) were clustered into five classes based on medical and psychiatric diagnoses: Minimal Comorbidity (23.2%); Chronic Pain-Osteoarthritis (30.1%); Depression-Chronic Pain (22.9%); Depression-Medical Comorbidity (16.5%); and High Comorbidity (7.3%). The patients in the Minimal Comorbidity and Chronic Pain-Osteoarthritis classes were most likely to attempt fatally compared with classes with a higher burden of comorbidities. Overall, 61% of the sample attempted fatally, and 82.5% of suicide decedents used firearms.

CONCLUSION

This study provides evidence that most comorbidity profiles (>50%) in primary care patients attempting suicide were characterized by minimal depression diagnoses and fatal attempts, mostly with firearms. These findings suggest that more than a depression diagnosis contributes to risk and that conversations about firearm safety by medical providers may play an important role in suicide intervention and prevention.

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.

Associations Between Gun Laws and Suicides

We examined the impact of a state gun law environment on suicides overall and within demographic subgroups. We linked 211,766 firearm suicides and 204,625 nonfirearm suicides in the 50 states of the United States for 2005-2015 to the population in each state, year, race/ethnicity, sex, and age, as well as to an index of state-level gun control. Difference-in-differences, zero-inflated, negative-binomial models were used to evaluate the impact of strengthening gun control on firearm and nonfirearm suicides. We subsequently stratified by sex and tested for interactions with race/ethnicity and age. We found 25 states strengthened gun control by an average of 6 points. Such an increase may result in a 3.3% (incidence rate ratio = 0.967; 95% confidence interval: 0.938, 0.996) decrease in firearm suicides. Although no impact on nonfirearm suicides was found overall, interaction models showed an increase in nonfirearm suicides among black men, white women, black women, and older individuals. Strengthening gun control may reduce firearm suicides overall but may increase nonfirearm suicides in some populations. The results indicate stricter gun laws should be advocated for and that additional policies are needed for populations who shifted to nonfirearm suicides.

Suicide in Parkinson's disease

Persons with Parkinson's disease (PwP) have many known risk factors for suicide and suicidal ideation (SI). Despite this, there is limited understanding of suicidality in this population. We conducted a systematic review to synthesise the available literature on suicidality in PwP and highlight areas for potential intervention and further research. We identified 116 articles discussing SI, suicidal behaviours, suicide attempts and/or fatal suicide in PwP. These articles describe prevalence, suicide methods, risk factors for suicide and SI and treatment of suicidality. In this review, we summarise the current literature and provide suggestions for how clinicians can identify and treat PwP who are at risk for suicide, for example, through aggressive treatment of depression and improved screening for access to lethal means.

Firearm legislation and statewide suicide rates: The moderating role of household firearm ownership levels

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.

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.

Psychopathic personality traits as a form of dispositional capability for suicide

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.

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.
