Prevalence and correlates of suicidal ideation among Operation Enduring Freedom and Operation Iraqi Freedom veterans

Predictive modeling of initiation and delayed mental health contact for depression

BACKGROUND

Depression is prevalent among Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) Veterans, yet rates of Veteran mental health care utilization remain modest. The current study examined: factors in electronic health records (EHR) associated with lack of treatment initiation and treatment delay; the accuracy of regression and machine learning models to predict initiation of treatment.

METHODS

We obtained data from the VA Corporate Data Warehouse (CDW). EHR data were extracted for 127,423 Veterans who deployed to Iraq/Afghanistan after 9/11 with a positive depression screen and a first depression diagnosis between 2001 and 2021. We also obtained 12-month pre-diagnosis and post-diagnosis patient data. Retrospective cohort analysis was employed to test if predictors can reliably differentiate patients who initiated, delayed, or received no mental health treatment associated with their depression diagnosis.

RESULTS

108,457 Veterans with depression, initiated depression-related care (55,492 Veterans delayed treatment beyond one month). Those who were male, without VA disability benefits, with a mild depression diagnosis, and had a history of psychotherapy were less likely to initiate treatment. Among those who initiated care, those with single and mild depression episodes at baseline, with either PTSD or who lacked comorbidities were more likely to delay treatment for depression. A history of mental health treatment, of an anxiety disorder, and a positive depression screen were each related to faster treatment initiation. Classification of patients was modest (ROC AUC = 0.59 95%CI = 0.586-0.602; machine learning F-measure = 0.46).

CONCLUSIONS

Having VA disability benefits was the strongest predictor of treatment initiation after a depression diagnosis and a history of mental health treatment was the strongest predictor of delayed initiation of treatment. The complexity of the relationship between VA benefits and history of mental health care with treatment initiation after a depression diagnosis is further discussed. Modest classification accuracy with currently known predictors suggests the need to identify additional predictors of successful depression management.

How well can U.S. military veterans' suicidal ideation be predicted from static and change-based indicators of their psychosocial well-being as they adapt to civilian life?

BACKGROUND

Identifying predictors of suicidal ideation (SI) is important to inform suicide prevention efforts, particularly among high-risk populations like military veterans. Although many studies have examined the contribution of psychopathology to veterans' SI, fewer studies have examined whether experiencing good psychosocial well-being with regard to multiple aspects of life can protect veterans from SI or evaluated whether SI risk prediction can be enhanced by considering change in life circumstances along with static factors.

METHODS

The study drew from a longitudinal population-based sample of 7141 U.S. veterans assessed throughout the first three years after leaving military service. Machine learning methods (cross-validated random forests) were applied to examine the predictive utility of static and change-based well-being indicators to veterans' SI, as compared to psychopathology predictors.

RESULTS

Although psychopathology models performed better, the full set of well-being predictors demonstrated acceptable discrimination in predicting new-onset SI and accounted for approximately two-thirds of cases of SI in the top strata (quintile) of predicted risk. Greater engagement in health promoting behavior and social well-being were most important in predicting reduced SI risk, with several change-based predictors of SI identified but stronger associations observed for static as compared to change-based indicator sets as a whole.

CONCLUSIONS

Findings support the value of considering veterans' broader well-being in identifying individuals at risk for suicidal ideation and suggest the possibility that well-being promotion efforts may be useful in reducing suicide risk. Findings also highlight the need for additional attention to change-based predictors to better understand their potential value in identifying individuals at risk for SI.

Psychometric Properties of the Self-Injurious Thoughts and Behaviors Interview-Short Form Among U.S. Active Duty Military Service Members and Veterans

We assessed the interrater reliability, convergent validity, and discriminant validity of the Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF) in a sample of 1,944 active duty service members and veterans seeking services for posttraumatic stress disorder (PTSD) and related conditions. The SITBI-SF demonstrated high interrater reliability and good convergent and discriminant validity. The measurement properties of the SITBI-SF were comparable across service members and veterans. Approximately 8% of participants who denied a history of suicidal ideation on the SITBI-SF reported suicidal ideation on a separate self-report questionnaire (i.e., discordant responders). Discordant responders reported significantly higher levels of PTSD symptoms than those who denied suicidal ideation on both response formats. Findings suggest that the SITBI-SF is a reliable and valid interview-based measure of suicide-related thoughts and behaviors for use with military service members and veterans. Suicide risk assessment might be optimized if the SITBI-SF interview is combined with a self-report measure of related constructs.

Mechanisms through which executive dysfunction influences suicidal ideation in combat-exposed Iraq and Afghanistan veterans

OBJECTIVE

Executive dysfunction has previously been associated with suicidality, but it remains unclear how deficits in executive functioning contribute to increased suicidal thoughts and behaviors. Although it has been proposed that poorer executive functioning leads to difficulty generating and implementing appropriate coping strategies to regulate distress and inhibit suicidal thoughts and behaviors, studies have not systematically examined these relationships. Therefore, the present study examined various hypotheses to elucidate the mechanisms through which executive dysfunction influences suicidal ideation (SI) in combat-exposed Iraq/Afghanistan veterans.

METHOD

Veterans who endorsed SI were compared to those who denied SI on demographic and diagnostic variables and measures of neuropsychological functioning, psychological symptoms, coping styles, and combat experiences. Serial mediation models were tested to examine mechanistic relationships among executive functioning, psychological distress, coping, and SI.

RESULTS

Those who endorsed SI had worse executive functioning, greater psychological distress, and greater avoidant coping relative to those who denied SI. Serial mediation model testing indicated a significant indirect path, such that executive dysfunction increased psychological distress, which in turn increased avoidant coping, leading to SI.

CONCLUSIONS

Findings support and extend previous hypotheses regarding how executive functioning contributes to increased risk of suicidality via increased distress and avoidant coping. Intervention efforts focused on reducing suicidality may benefit from techniques that enhance executive functioning (e.g. computerized training, cognitive rehabilitation) and in turn reduce distress prior to targeting coping strategies.

The First Year After Military Service: Predictors of U.S. Veterans' Suicidal Ideation

INTRODUCTION

Little is known about predictors of military veterans' suicidal ideation as they transition from service to civilian life, a potentially high-risk period that represents a critical time for intervention. This study examined factors associated with veterans' suicidal ideation in the first year after military separation.

METHODS

A national sample of U.S. veterans (N=7,383) from The Veterans Metrics Initiative Study reported on their mental health, psychosocial well-being, and demographic/military characteristics in an online survey at 3 and 9 months after separation. Cross-validated random forest models and mean decrease in accuracy values were used to identify key predictors of suicidal ideation. Bivariate ORs were calculated to examine the magnitude and direction of main effects associations between predictors and suicidal ideation. Data were collected in 2016/2017 and analyzed in 2021.

RESULTS

In the first year after separation, 15.1% of veterans reported suicidal ideation. Endorsing depression symptoms and, to a lesser extent, identifying oneself as experiencing depression, were most predictive of suicidal ideation. Other psychopathology predictors included higher anxiety and posttraumatic stress disorder symptoms. Psychosocial well-being predictors included higher health satisfaction and functioning, community satisfaction and functioning, and psychological resilience. Logistic models performed similarly to random forest models, suggesting that relationships between predictors and suicidal ideation were better represented as main effects than interactions.

CONCLUSIONS

Results highlight the potential value of bolstering key aspects of military veterans' mental health and psychosocial well-being to reduce their risk for suicidal ideation in the first year after separation. Findings can inform interventions aimed at helping veterans acclimate to civilian life.

Resilience to Suicidal Ideation Among U.S. Military Veterans with Posttraumatic Stress: Results from the National Health and Resilience in Veterans Study

Veterans with combat exposure experience high rates of posttraumatic stress symptoms (PTSS) and associated suicidal ideation. The current study examined whether social support (i.e., social connectedness and social engagement) and protective psychological factors (i.e., resilience and altruism) moderated the relation between PTSS and suicidal ideation severity in a sample of 149 U.S. military combat veterans who served in the Vietnam War or Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND). Consistent with expectations, initial PTSS were positively associated with concurrent and three-year follow-up severity of suicidal ideation. Moderation analyses revealed the relation between initial PTSS and concurrent suicidal ideation severity was no longer significant at above average levels of social connectedness, social engagement, and psychological resilience. Further, the relation between initial PTSS and suicidal ideation severity three years later continued to be buffered by above average levels of social engagement. Results suggest social connectedness, psychological resilience, and social engagement help moderate initial severe thoughts of suicide linked to PTSS, while social engagement might be the strongest protective factor against severe suicidal ideation over time. Empirically-supported prevention and treatment efforts enhancing social engagement may help promote resilience to severe PTSS-related suicidal ideation among veterans from Vietnam and OEF/OIF/OND combat eras.

Models of Trauma Exposure, Depression, and Suicidality in Safety-Net Primary Care

Suicidality is a major public health concern, particularly for low-income, trauma-exposed patients with limited access to mental health providers. However, limited research has modeled pathways of suicidality in safety-net primary care samples. Patients (N = 207) in a safety-net primary care clinic completed measures of childhood and adult trauma exposure, depression, and suicidality. Participants (M age = 44.8 years, SD = 11.6), were 60.4% male, 63.8% Black/African American, and predominantly low-income (i.e., 69.1% reported an annual income less than $5,000 USD). Half of the sample reported at least four childhood traumatic events (M = 3.9 events, SD = 3.0) and approximately three adult traumatic events (M = 3.0 events, SD = 2.1). Most participants (82.1%) reported significant depressive symptoms, and 43.5% endorsed recent suicidality. Models showing the mediational effect of depression on the association between trauma exposure and suicidality, β = .20, B = 0.23, SE = 0.05, 95% CI [0.16, 0.32], and the moderational effect of trauma exposure on the association between depression and suicidality, β = .16, B = 0.20, SE = 0.08, p = .007, were both supported. These results underscore the high prevalence of trauma exposure, depression, and suicidality in a safety-net primary care sample. They also highlight the pervasiveness and complexity of suicidality in low-income primary care patients, emphasize the importance of trauma-informed suicide assessment, and identify trauma sequelae and depression as potential treatment targets to reduce suicidality.

Is Emotion Dysregulation Associated With Suicidal Ideation in Post 9/11 Veterans?

Emotion dysregulation, a risk factor for suicide ideation and attempts, has not been studied in U.S. veterans of Operations Enduring and Iraqi Freedom and New Dawn (OEF/OIF/OND). Data were collected through standardized telephone interviews and computer-based surveys from 278 OEF/OIF/OND veterans (70.6% male, 29.4% female). Bivariate analyses indicated that emotion dysregulation was associated with suicidal ideation during the past-three-months (r = 0.30, p < 0.05) and lifetime suicide attempts (r = 0.21, p < 0.05). When PTSD and depression symptoms were added to a sequential logistic regression model, emotion dysregulation was no longer significantly associated with ideation or attempt. Emotion dysregulation was associated with suicidal ideation and attempt; however, current distress had greater associations. Dysregulation is one of several factors in veteran suicide risk.

Deployment and Psychological Correlates of Suicide Ideation: A Prospective, Longitudinal Study of Risk and Resilience Among Combat Veterans

INTRODUCTION

Suicide rates among military personnel have risen in part due to war zone deployments. Yet, the degree to which deployment-related stressors, in combination with preexisting and co-occurring psychiatric symptoms and individual resilience factors, contribute to suicide ideation (SI) remains unclear. The current study leverages prospective, longitudinal data to examine both risk and protective factors associated with SI in deployed service members.

MATERIALS AND METHODS

Participants were 1,805 active duty enlisted Marines and Navy service members assessed before and after a 7-month deployment for SI, preexisting and concurrent symptoms of depression, post-traumatic stress disorder (PTSD), alcohol consumption, as well as prior and deployment-related traumatic brain injury (TBI). Current self-reported psychological resilience and social support were analyzed as potential protective factors.

RESULTS

Rates of SI were 7.3% and 3.9% before and after deployment, respectively. Of those with post-deployment SI, 68.6% were new-onset cases. Multivariate regression revealed that concurrent mild depression was the strongest risk factor (odds ratio [OR] = 10.03, 95% CI 5.28-19.07). Other significant risk factors included prior SI (OR = 3.36, 95% CI 1.60-7.05), prior subthreshold PTSD (OR = 2.10, 95% CI 1.10-3.99), and deployment TBI (OR = 1.84, 95% CI 1.03-3.28). Controlling for clinical symptoms and TBI, the risk of SI was reduced for those with moderate (OR = 0.50, 95% CI 0.27-0.93) and high psychological resilience scores (OR = 0.25, 95% CI 0.08-0.79) after deployment.

CONCLUSIONS

Results indicate that even mild symptoms of depression and PTSD may increase the risk of SI. Screening for subthreshold clinical symptoms and TBI while incorporating psychological resilience training would allow for a more multidimensional approach to suicide risk assessment.

Posttraumatic Stress Disorder, Suicidal Ideation, and Suicidal Self-Directed Violence Among U.S. Military Personnel and Veterans: A Systematic Review of the Literature From 2010 to 2018

Rates of suicide and posttraumatic stress disorder remain high among United States military personnel and veterans. Building upon prior work, we conducted a systematic review of research published from 2010 to 2018 regarding: (1) the prevalence of suicidal ideation, suicide attempt, and suicide among United States military personnel and veterans diagnosed with posttraumatic stress disorder; (2) whether posttraumatic stress disorder was associated with suicidal ideation, suicide attempt, and suicide among United States military personnel and veterans. 2,106 titles and abstracts were screened, with 48 articles included. Overall risk of bias was generally high for studies on suicidal ideation or suicide attempt and low for studies on suicide. Across studies, rates of suicidal ideation, suicide attempt, and suicide widely varied based on study methodology and assessment approaches. Findings regarding the association between posttraumatic stress disorder diagnosis with suicidal ideation and suicide were generally mixed, and some studies reported that posttraumatic stress disorder was associated with lower risk for suicide. In contrast, most studies reported significant associations between posttraumatic stress disorder and suicide attempt. These findings suggest complex associations between posttraumatic stress disorder and suicidal ideation, suicide attempt, and suicide, which are likely influenced by other factors (e.g., psychiatric comorbidity). In addition, most samples were comprised of veterans, rather than military personnel. Further research is warranted to elucidate associations between posttraumatic stress disorder and suicidal ideation, suicide attempt, and suicide, including identification of moderators and mediators of this relationship. Addressing this among United States military personnel, by gender, and in relation to different trauma types is also necessary.

Summarizing Complex Graphical Models of Multiple Chronic Conditions Using the Second Eigenvalue of Graph Laplacian: Algorithm Development and Validation

Background

It is important but challenging to understand the interactions of multiple chronic conditions (MCC) and how they develop over time in patients and populations. Clinical data on MCC can now be represented using graphical models to study their interaction and identify the path toward the development of MCC. However, the current graphical models representing MCC are often complex and difficult to analyze. Therefore, it is necessary to develop improved methods for generating these models.

Objective

This study aimed to summarize the complex graphical models of MCC interactions to improve comprehension and aid analysis.

Methods

We examined the emergence of 5 chronic medical conditions (ie, traumatic brain injury [TBI], posttraumatic stress disorder [PTSD], depression [Depr], substance abuse [SuAb], and back pain [BaPa]) over 5 years among 257,633 veteran patients. We developed 3 algorithms that utilize the second eigenvalue of the graph Laplacian to summarize the complex graphical models of MCC by removing less significant edges. The first algorithm learns a sparse probabilistic graphical model of MCC interactions directly from the data. The second algorithm summarizes an existing probabilistic graphical model of MCC interactions when a supporting data set is available. The third algorithm, which is a variation of the second algorithm, summarizes the existing graphical model of MCC interactions with no supporting data. Finally, we examined the coappearance of the 100 most common terms in the literature of MCC to validate the performance of the proposed model.

Results

The proposed summarization algorithms demonstrate considerable performance in extracting major connections among MCC without reducing the predictive accuracy of the resulting graphical models. For the model learned directly from the data, the area under the curve (AUC) performance for predicting TBI, PTSD, BaPa, SuAb, and Depr, respectively, during the next 4 years is as follows—year 2: 79.91%, 84.04%, 78.83%, 82.50%, and 81.47%; year 3: 76.23%, 80.61%, 73.51%, 79.84%, and 77.13%; year 4: 72.38%, 78.22%, 72.96%, 77.92%, and 72.65%; and year 5: 69.51%, 76.15%, 73.04%, 76.72%, and 69.99%, respectively. This demonstrates an overall 12.07% increase in the cumulative sum of AUC in comparison with the classic multilevel temporal Bayesian network.

Conclusions

Using graph summarization can improve the interpretability and the predictive power of the complex graphical models of MCC.

Depression and PTSD-related anhedonia mediate the association of military sexual trauma and suicidal ideation in female service members/veterans

Previous research shows a direct link between military sexual trauma and suicide risk. Little is known about mediators of this association, including posttraumatic stress disorder (PTSD) or depression severity, mental health conditions that are correlated with both suicide risk and military sexual trauma. Moreover, existing studies of military sexual trauma do not distinguish between harassment and assault, resulting in a gap in our knowledge regarding suicide risk as a function of sexual trauma type. We explored whether PTSD symptom clusters and depression mediated the association of military sexual trauma type (none, harassment-only, assault) and suicidal ideation (SI). Female service members/Veterans (n = 1190) completed a demographic inventory, military sexual trauma history and type screening, and PTSD symptom cluster severity, depression severity, and SI measures. Structural equation modeling revealed that the association of military sexual trauma, particularly assault, with SI was mediated by depression severity and PTSD-related anhedonia. Screening for SI among those endorsing a history of military sexual trauma, PTSD-related anhedonia, and depression may help identify those at risk for SI. Therapeutic interventions aimed at reducing PTSD-related anhedonia and depression symptoms may be the most efficient way to mitigate suicide risk in those with histories of assault military sexual trauma.

Social Ties and Suicidal Ideation Among Veterans Referred to a Primary Care-Mental Health Integration Program

OBJECTIVE

This study examined associations between three indices of social ties (perceived social support, frequency of negative social exchanges, and degree of social integration) and suicidal ideation among veterans referred by their primary care provider for a behavioral health assessment.

METHODS

The sample included 15,277 veterans who completed a mental health and substance use assessment on referral to a Primary Care-Mental Health Integration (PCMHI) program. Data on sociodemographic factors, mental health and substance use conditions (e.g., depression, anxiety, and substance use), perceived general health, the three indices of social ties, and suicidal ideation were extracted from clinical interviews.

RESULTS

The mean±SD age of the sample was 51.3±15.9, most (89%) were men, and about half (48%) were white. Most met criteria for at least one mental health or substance use condition on PCMHI assessment, and 39% reported either low- or high-severity suicidal ideation, as measured by the Paykel Suicide Scale. Logistic regression analyses indicated that after adjustment for sociodemographic factors, perceived health, and comorbid mental health and substance use conditions, each of the three social tie indices was uniquely associated with higher odds of reporting suicidal ideation, compared with no ideation.

CONCLUSIONS

Findings underscore the value of assessing multiple indices of social ties when examining suicidal ideation among high-risk veterans in primary care experiencing behavioral health issues. Incorporating an assessment of the quality of patients' social interactions and level of social integration into routine PCMHI practice has the potential to enhance screening and intervention efforts aimed at reducing suicidal ideation.

Pain and modifiable risk factors among weight loss seeking Veterans with overweight

OBJECTIVE

Overweight/obesity and chronic pain frequently co-occur and demonstrate a bidirectional relationship. Modifiable risk factors, such as eating behaviors and mental health symptoms, may be important to understand this relationship and improve interventions in Veterans.

DESIGN

Cross-sectional.

SETTING

Veterans Health Administration Medical Center outpatient clinic.

SUBJECTS

The sample of Veterans (N = 126) was mostly male (89.7%), White (76%), and non-Hispanic (94%) with average age of 61.9 years (SD = 8.5) and average body mass index (BMI) of 38.5 (SD = 7.5).

METHODS

Veterans referred for weight loss treatment (MOVE!) at VA Connecticut completed self-report questionnaires, and electronic medical records were reviewed.

RESULTS

Mean self-reported pain rating was 4.5 out of 10 (SD = 2.3). Moderate to severe pain was endorsed by 60% of the sample. Veterans with higher pain intensity and interference reported higher global eating disorder symptoms, emotional overeating, night eating, insomnia severity, and mental health symptoms (all p's < 0.01). However, pain intensity and interference were not associated with BMI.

CONCLUSIONS

For Veterans seeking behavioral weight loss treatment, higher pain intensity and interference were associated with more severe eating disorder, sleep, and mental health symptoms. A better description of the clinical characteristics of Veterans with pain who participate in MOVE! highlights their unique needs and may improve treatments to address pain in the context of weight loss treatment.

Psychiatric Emergencies: Assessing and Managing Suicidal Ideation

The assessment of suicide risk is a daunting, but increasingly frequent task for outpatient practitioners. Guidelines for depression screening identify more individuals at risk for treatment and mental health resources are not always easily accessible. For those patients identified as in need of a formal suicide risk assessment, this article reviews established risk and protective factors for suicide and provides a framework for the assessment and management of individuals at risk of suicide. The assessment should be explicitly documented with a summary of the most relevant risk/protective factors for that individual with a focus on interventions that may mitigate risk.

Protocol for the evaluation of a digital storytelling approach to address stigma and improve readiness to seek services among veterans

BACKGROUND

Research suggests that at least 10% of veterans returning from Iraq and Afghanistan meet criteria for posttraumatic stress disorder (PTSD) related to their military experiences. National dissemination initiatives have increased veterans' access to best-practice interventions. However, treatment-seeking remains low among veterans with PTSD, often due to perceived stigma and other associated barriers. The National Center for PTSD recently developed and launched AboutFace, a digital storytelling (DST) resource designed to help veterans recognize PTSD and motivate them to seek evidence-based treatment. The Ralph H. Johnson Veterans Affairs Medical Center (VAMC) and the National Center for PTSD have partnered to conduct pilot work to evaluate veterans' reactions to AboutFace to set the stage for a large-scale study to examine whether AboutFace effectively reduces stigma and improves attitudes toward treatment-seeking among veterans. If effective, this DST approach may serve as a valuable national model for a variety of treatment-seeking populations.

METHODS

During the first phase of the pilot, in-person usability assessments of AboutFace will be conducted via semi-structured interviews with 20 veterans. Audio recordings of interviews will undergo transcription and coding. A report of the results of qualitative analyses of these interviews will be provided to the National Center for PTSD and will inform revisions to the site. In the second phase of the pilot, 60 veterans referred to a specialized PTSD clinic will be recruited to demonstrate and refine the methodology that we propose to use in a larger randomized controlled trial evaluation of AboutFace. Veterans will be randomly assigned to receive AboutFace plus standard education vs. standard education alone. Baseline and 2-week telephone assessments will be conducted with participating veterans to measure stigma, attitudes toward seeking mental health services, and treatment access/engagement.

DISCUSSION

The feedback we receive in this pilot will be used to strengthen the quality of the DST website in preparation for a large-scale evaluation. Future work will involve evaluation of reach and impact of the site relative to stigma, attitudes toward seeking mental health service, and utilization of care. If AboutFace is found to increase access to care, this finding would have broad and significant implications for overcoming barriers to care for veterans and other populations with stigmatized conditions.

The relationship between childhood poverty, military service, and later life depression among men: Evidence from the Health and Retirement Study

BACKGROUND

Childhood poverty has been associated with depression in adulthood, but whether this relationship extends to later life major depression (MD) or is modified by military service is unclear.

METHODS

Data come from the Health and Retirement Study (HRS) 2010 wave, a longitudinal, nationally representative study of older adults. Men with data on military service and childhood poverty were included (N=6330). Childhood poverty was assessed by four indicators (i.e., parental unemployment, residential instability) experienced before age 16. Military service was categorized as veteran versus civilian, and during draft versus all-volunteer (after 1973) eras. Past year MD was defined by the Composite International Diagnostic Inventory.

RESULTS

Four in ten men ever served, with 13.7% in the all-volunteer military. Approximately 12% of civilians, 8% draft era and 24% all-volunteer era veterans had MD. Childhood poverty was associated with higher odds of MD (Odds Ratio (OR): 2.38, 95% Confidence Interval (CI): 1.32-4.32) and higher odds of military service (OR: 2.58, 95% CI: 1.58-4.21). Military service was marginally associated with MD (OR: 1.28, 95% CI: 0.98-1.68) and did not moderate the association between childhood poverty and MD.

LIMITATIONS

Self-report data is subject to recall bias. The HRS did not assess childhood physical and emotional abuse, or military combat exposure.

CONCLUSIONS

Men raised in poverty had greater odds of draft and all-volunteer military service. Early-life experiences, independent of military service, appear associated with greater odds of MD. Assessing childhood poverty in service members may identify risk for depression in later life.

Improving Treatment Engagement for Returning Operation Enduring Freedom and Operation Iraqi Freedom Veterans With Posttraumatic Stress Disorder, Depression, and Suicidal Ideation

Posttraumatic stress disorder (PTSD) is associated with increased risk of suicidal ideation among veterans of Operation Enduring Freedom and Operation Iraqi Freedom. This report examined the effectiveness of a brief phone-based cognitive-behavioral intervention on treatment seeking among suicidal and nonsuicidal Operation Enduring Freedom and Operation Iraqi Freedom veterans who screened positive for PTSD. Participants were randomized to the intervention or control conditions. We found that suicidal participants, regardless of condition, were twice as likely to attend treatment as nonsuicidal participants. Participants assigned to the control condition who did not indicate suicidality at baseline were less likely to attend treatment at both the 1- and 6-month follow-up interviews. Qualitative findings of the suicidal participants indicated PTSD and depressive symptoms, low social support, and infrequent positive coping mechanisms. Our finding indicates the effectiveness of an intervention to motivate veterans with PTSD to initiate and remain in treatment. The intervention might be particularly useful prior to experiencing a psychological crisis.

Does Reintegration Stress Contribute to Suicidal Ideation Among Returning Veterans Seeking PTSD Treatment?

Although posttraumatic stress disorder (PTSD) and other psychiatric symptoms are well-established risk factors for suicidal ideation among returning veterans, less attention has been paid to whether the stress of reintegrating into civilian society contributes to suicidal ideation. Utilizing a sample of 232 returning veterans (95% male, mean age = 33.63 years) seeking PTSD treatment, this study tested whether reintegration difficulties contribute to suicidal ideation over and above the influence of PTSD symptoms, depression symptoms, and potential substance misuse. Logistic regressions indicated that reintegration stress had a unique effect on suicidal ideation over and above PTSD and depression symptoms. Reintegration stress interacted with substance misuse to predict suicidal ideation, such that the effect of reintegration stress on suicidal ideation was much larger for those with potential substance misuse. Exploratory analyses also examined which types of reintegration difficulties were associated with suicidal ideation, and found that difficulty maintaining military friendships, difficulty getting along with relatives, difficulty feeling like you belong in civilian society, and difficulty finding meaning/purpose in life were all significantly associated with suicidal ideation, beyond the effects of psychiatric symptoms and potential substance misuse. Findings highlight the importance of addressing reintegration stress for the prevention of suicide among returning veterans. Implications for treatment are discussed.

Prevalence and correlates of suicidal ideation and suicide attempts among veterans in primary care referred for a mental health evaluation

BACKGROUND

The Veterans Health Administration has made concerted efforts to increase mental health services offered in primary care. However, few studies have evaluated correlates of suicidal ideation and suicide attempt in veterans in primary care-mental health integration (PCMHI). The purpose of the present study is to examine associations between suicidal ideation and suicide attempts as dependent variables and demographic and clinical factors as the independent variables.

METHODS

Veterans (n=3004) referred from primary care to PCMHI were contacted for further assessment, which included past-year severity of suicidal thoughts (none, low, high) and attempts using the Paykel Suicide Scale, mental health disorders, and illicit drug use. Multinomial logistic regression models were used to identify correlates of suicidal ideation and suicide attempts.

RESULTS

Thoughts of taking one's life was endorsed by 24% of participants and suicide attempts were reported in 2%. In adjusted models, depression, psychosis, mania, PTSD and generalized anxiety disorder were associated with high severity suicidal ideation, but not suicide attempt. Illicit drug use was not associated with suicidal ideation, but was the only variable associated with suicide attempt.

LIMITATIONS

The study was cross-sectional, focused on one clinical setting, and the suicide attempt analyses had limited power.

CONCLUSIONS

PCMHI is a critical setting to assess suicidal ideation and suicide attempt and researchers and clinicians should be aware that the differential correlates of these suicide-related factors. Future research is needed to identify prospective risk factors and assess the utility of follow-up care in preventing suicide.

Measurement Scales of Suicidal Ideation and Attitudes: A Systematic Review Article

Background: The main aim of this study was to accumulate research evidence that introduce validated scales to measure suicidal attitudes and ideation and provide an empirical framework for adopting a relevant assessment tool in studies on suicide and suicidal behaviors.

Methods: Medical Subject Headings’ (MeSH) terms were used to search Ovid Medline, PROQUEST, Wiley online library, Science Direct and PubMed for the published articles in English that reported application of an scale to measure suicidal attitudes and ideation from January 1974 onward.

Results: Fourteen suicidal attitude scale and 15 scales for assessing suicidal ideation were identified in this systematic review. No gold standard approach was recognized to study suicide related attitudes and ideations.

Conclusion: Special focus on generally agreed dimensions of suicidal ideation and attitudes and cross-cultural validation of the introduced scales to be applicable in different ethnic and socially diverse populations could be a promising area of research for scholars.

Suicide risk in Iraq and Afghanistan veterans with mental health problems in VA care

Suicide rates among U.S. military personnel and veterans are a public health concern, and those with mental health conditions are at particular risk. We examined demographic, military, temporal, and diagnostic associations with suicidality in veterans. We conducted a population-based, retrospective cohort study of all Iraq and Afghanistan war veterans who screened positive for posttraumatic stress disorder (PTSD) and/or depression, received a suicide risk assessment, and endorsed hopelessness about the present or future after their last deployment and between January 1, 2010 and June 29, 2014 (N = 45,741). We used bivariate and multivariate logistic regression analyses to examine variables associated with having endorsed suicidal thoughts and a plan. Multiple factors were associated with suicidality outcomes, including longer time from last deployment to screening (proxy for time to seeking VA care), an alcohol use disorder diagnosis, further distance from VA (rurality), and being active duty during military service. Hispanic veterans were at decreased risk of having suicidal ideation and a plan, compared to their white counterparts. In high-risk veterans, some of the strongest associations with suicidality were with modifiable risk factors, including time to VA care and alcohol use disorder diagnoses. Promising avenues for suicide prevention efforts can include early engagement/intervention strategies with a focus on amelioration of high-risk drinking.

Correlates of suicide among veterans treated in primary care: case-control study of a nationally representative sample

BACKGROUND

Veterans receiving Veterans Affairs (VA) healthcare have increased suicide risk compared to the general population. Many patients see primary care clinicians prior to suicide. Yet little is known about the correlates of suicide among patients who receive primary care treatment prior to death.

OBJECTIVE

Our aim was to describe characteristics of veterans who received VA primary care in the 6 months prior to suicide; and to compare these to characteristics of control patients who also received VA primary care.

DESIGN

This was a retrospective case-control study.

SUBJECTS

The investigators partnered with VA operations leaders to obtain death certificate data from 11 states for veterans who died by suicide in 2009. Cases were matched 1:2 to controls based on age, sex, and clinician.

MAIN MEASURES

Demographic, diagnosis, and utilization data were obtained from VA's Corporate Data Warehouse. Additional clinical and psychosocial context data were collected using manual medical record review. Multivariate conditional logistic regression was used to examine associations between potential predictor variables and suicide.

KEY RESULTS

Two hundred and sixty-nine veteran cases were matched to 538 controls. Average subject age was 63 years; 97 % were male. Rates of mental health conditions, functional decline, sleep disturbance, suicidal ideation, and psychosocial stressors were all significantly greater in cases compared to controls. In the final model describing men in the sample, non-white race (OR = 0.51; 95 % CI = 0.27-0.98) and VA service-connected disability (OR = 0.54; 95 % CI = 0.36-0.80) were associated with decreased odds of suicide, while anxiety disorder (OR = 3.52; 95 % CI = 1.79-6.92), functional decline (OR = 2.52; 95 % CI = 1.55-4.10), depression (OR = 1.82; 95 % CI = 1.07-3.10), and endorsement of suicidal ideation (OR = 2.27; 95 % CI = 1.07-4.83) were associated with greater odds of suicide.

CONCLUSIONS

Assessment for anxiety disorders and functional decline in addition to suicidal ideation and depression may be especially important for determining suicide risk in this population. Continued development of interventions that support identifying and addressing these conditions in primary care is indicated.

Suicidal ideation and mental distress among adults with military service history: results from 5 U.S. states, 2010

OBJECTIVES

We examined the association of military service history with past-year suicidal ideation and past-30-days mental distress in a probability-based sample of adults.

METHODS

We gathered 2010 Behavioral Risk Factor Surveillance System data from 5 states that asked about past-year suicidal ideation. Military service was defined as current or former active-duty service or National Guard or Reserves service. We stratified analyses into 18 to 39 years, 40 to 64 years, and 65 years and older age groups and used multiple logistic regression analyses, adjusted for demographic confounders, to discern the association of military service history with past-year suicidal ideation and past-30-days mental distress.

RESULTS

Among the 26,736 respondents, 13.1% indicated military service history. After adjusting for several confounders, we found military history status among those aged 40 to 64 years was associated with both past-year suicidal ideation and past-30-days mental distress. We found no significant associations among the younger or older age groups.

CONCLUSIONS

Differences in suicidal ideation between military and nonmilitary individuals may occur in midlife. Future research should examine the possibility of cohort effects, service era effects, or both.

Mental health utilization of new-to-care Iraq and Afghanistan Veterans following suicidal ideation assessment

We evaluated the impact of brief structured suicidal ideation (SI) assessments on mental health care among new-to-care Operations Enduring Freedom and Iraqi Freedom (OEF/OIF) veterans. National datasets provided military, demographic, and clinical information. For all new-to-care OEF/OIF veterans administered depression screens (PHQ-2: Patient Health Questionnaire-2) and structured SI assessments in primary care or ambulatory mental health settings of three Veterans Affairs (VA) Medical Centers between April 2008 and September 2009 (N=465), generalized estimating equations were used to examine associations between SI and number of subsequent-year specialty mental health visits and antidepressant prescriptions. Approximately one-third of the veterans reported SI. In multivariate models, PTSD and anxiety diagnoses, severe depression symptoms, being married, and SI assessment by a mental health clinician were associated with more mental health visits in the subsequent year. Depression, PTSD, and anxiety diagnoses, and SI assessment by a mental health clinician were associated with receiving antidepressants. Presence of SI did not significantly affect subsequent year mental health utilization when adjusting for diagnostic and clinician variables, but inaugural visits involving mental health clinicians were consistently associated with subsequent mental health care.

Primary care clinician responses to positive suicidal ideation risk assessments in veterans of Iraq and Afghanistan

OBJECTIVE

To examine primary care clinician actions following positive suicide risk assessments administered to Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans.

METHODS

We identified OEF/OIF veterans with positive templated suicide risk assessments administered in primary care settings of three Veterans Affairs (VA) Medical Centers. National VA datasets and manual record review were used to identify and code clinician discussions and actions following positive assessments. Bivariate analyses were used to examine relationships between patient characteristics and discussions of firearms access and alcohol/drug use.

RESULTS

Primary care clinicians documented awareness of suicide risk assessment results for 157 of 199 (79%) patients with positive assessments. Most patients were assessed for mental health conditions and referred for mental health follow-up. Clinicians documented discussions about firearms access for only 15% of patients. Among patients whose clinicians assessed for substance abuse, 34% received recommendations to reduce alcohol or drug use. Depression diagnoses and suicidal ideation/behavior severity were significantly associated with firearms access discussions, while patient sex, military service branch, and substance abuse diagnoses were significantly associated with recommendations to reduce substance use.

CONCLUSION

Greater efforts are needed to understand barriers to clinicians' assessing, documenting and counseling once suicidal ideation is detected, and to develop training programs and systems changes to address these barriers.

The spiritual health of veterans with a history of suicide ideation

Introduction: In recent years, considerable empirical attention has been devoted to examining the increased risk of suicide observed in some Veteran populations. This has led to a renewed focus on developing novel support options which can be used to respond to Veterans in distress, reducing their risk of suicide. Spirituality and religion, however, have been largely absent from any public discourse related to suicide prevention, not least of all in Veteran populations. Aim: The aim of this cross-sectional study is to compare the self-rated spiritual health of Veterans with and without suicide ideation. Identifying differences which may exist between these two groups could highlight the relevance of spiritual well-being to Veteran suicide prevention efforts. Materials and Methods: Data were collected using pencil-and-paper surveys, called Spiritual Assessments, distributed within the general population of in- and outpatients at a U.S. Department of Veterans Affairs Medical Center. Using Likert-type scales, this study examines the self-rated spiritual health, spiritual devotion, and significance ascribed to spirituality in a sample of 5378 Veterans. Statistical analysis took place using chi-squared to examine differences in the distribution of responses between ideators and non-ideators. Results: Ideators significantly more often rated their spiritual health as worse than that of non-ideators. Even with similar levels of spiritual devotion or significance ascribed to spiritual life, ideators continued to significantly more often rate their spiritual health as worse than that of non-ideators. Conclusion: The results show that Veterans with suicide ideation more often rate their spiritual health as worse than that of Veterans without suicide ideation. This suggests that spiritual well-being may indeed be relevant to suicide prevention efforts in Veteran populations.
