Mood, anxiety, and substance-use disorders and suicide risk in a military population cohort

A conditional process analysis of suicidal thoughts and behaviors in outpatient parents: Examining the Narrative Crisis Model by parenthood status

No study to date has examined the moderating effect of parenthood on suicidal states and outcomes using a conditional process model. The Narrative Crisis Model, a multi-stage model from interpersonal distress to suicidal outcomes mediated by Suicide Crisis Syndrome severity, was assessed (H1). The present study tested whether (H2) parenthood moderates the indirect association between interpersonal distress and suicidality to reduce suicide risk. Psychiatric outpatients (N = 466) completed measures assessing the severity of interpersonal distress and Suicide Crisis Syndrome, as well as a clinical interview of suicidal thoughts and behaviors. The sample was predominantly female (65.7%), with ages ranging from 18 to 84 years. Mediation was conducted on the total sample (H1) and a conditional process analysis compared parents (n = 170) and non-parents (H2). Suicide Crisis Syndrome severity mediated the relationship between interpersonal distress and suicidal outcomes. Parenthood moderated the indirect relationship between interpersonal distress and suicidal outcomes through Suicide Crisis Syndrome such that parents had a significantly higher suicide risk than non-parents (index = 0.058; 95% CI [0.005, 0.139]). In the context of an outpatient population, parents appear to be more at risk for developing a suicidal crisis and engaging in suicidal thoughts and behaviors than non-parents. Parenthood may act as a pile-up stressor for this population, outweighing the protective effects of having children. In this way, the Narrative Crisis Model is a theoretical model suitable for the examination of complex factors impacting risk for near-term suicidal thoughts and behaviors.

Evaluation of Training in Identifying and Responding to Suicide Risk by Staff of a Behavioral Health Managed Care Organization

PURPOSE OF STUDY

Gatekeeper training for individuals who may be in contact with someone contemplating suicide is a recommended suicide prevention strategy. This study assessed organizational-level gatekeeper training.

PRIMARY CARE SETTINGS

Gatekeeper training was conducted in a behavioral health managed care organization (BHMCO), which facilitates integrated behavioral and physical health services for 1.4 million Medicaid-enrolled Pennsylvanians.

METHODOLOGY AND SAMPLE

Gatekeeper training was offered to BHMCO staff via a new training policy. Gatekeeper trainers were qualified BHMCO staff. Approximately half (47%) of trained staff served as care managers. Pre- and posttraining surveys were administered to assess self-reported confidence in ability to identify and assist individuals at risk for suicide. Post-training, staff responded to a hypothetical vignette involving suicide risk, which was evaluated for skills by gatekeeper trainers.

RESULTS

Eighty-two percent of staff completed training. Mean confidence scores improved significantly from pre- (η = 615) to posttraining (η = 556) (understanding = 3.41 vs. 4.11, respectively; knowledge = 3.47 vs. 4.04; identification = 3.30 vs. 3.94; respond = 3.30 vs. 4.04, p < .0001 for each). Intermediate and advanced skills to address suicide risk were demonstrated post-training in 68.6% and 17.2% of staff, respectively. More care managers versus other BHMCO staff demonstrated advanced skills (21.6% vs. 13.0%); however, both groups showed significant improvement pre- to post-training.

IMPLICATIONS FOR CASE MANAGEMENT

Care managers benefit from suicide prevention training and are uniquely positioned to serve as organizational leaders to successful population health initiatives to decrease suicide through training and education.

Suicide Risk in Military Personnel during the COVID-19 Health Emergency in a Peruvian Region: A Cross-Sectional Study

Military personnel represent a frontline group exposed to multiple stressors. These factors have increased during the COVID-19 pandemic, predisposing to the development of suicidal risk (SR). Given the few studies conducted in this population, we evaluated the prevalence of SR and its associated factors during the health emergency. A cross-sectional survey study was conducted in person among 514 participants in Lambayeque, Peru in 2021. The outcome was SR, and the exposures were depression (PHQ-9), anxiety (GAD-7), PTSD (PCL-C), and other sociodemographic variables. The prevalence of SR was 14.0% (95% CI: 11.12-17.31%) and was significantly higher in people with a family history of mental health (PR: 2.16; 95% CI: 1.13-4.15) and in those with moderate clinical insomnia (PR: 2.21; 95% CI: 1.19-4.12). Military personnel with high resilience had a lower prevalence of SR (PR: 0.54, CI: 0.31-0.95). Anxiety was associated with a higher prevalence of SR (PR: 3.27; 95% CI: 1.76-6.10). Our findings show that at least 1 out of 10 military personnel are at risk of suicide. Special attention should be paid to the associated factors to develop interventions and reverse their consequences. These results may be useful in policy implementation and general statistics of SR in the local and regional context.

Incidences of anxiety disorders among active duty service members between 1999 and 2018

PURPOSE

Anxiety disorders can impact the health, performance, and retention of military service members. To inform prevention initiatives and long-term treatment planning, incidence rates across anxiety disorders were evaluated among U.S. active-duty service members over a 20-year period.

METHOD

Data were extracted from the Defense Medical Epidemiological Database to examine incidence rates of generalized anxiety disorder (GAD), panic disorder (PD), agoraphobia (AG), social anxiety disorder (SAD), obsessive compulsive disorder (OCD), agoraphobia with panic disorder (AWPD), agoraphobia without history of panic disorder (AWOPD), and unspecified anxiety disorder (UAD) among 151,844 service members between 1999 and 2018 in relation to sex, age, race, marital status, military pay grade, service branch.

RESULTS

Incidence rates of anxiety disorders increased significantly over the 20-year period. Anxiety disorder incidence rates ranged widely from 0.01 to 23.70 (per 1000 service members). There were significant differences in observed versus expected diagnostic rates across all demographic variables examined (p < 0.001).

CONCLUSION

Incidence rates varied considerably across the anxiety disorders, with UAD being the highest. These data highlight the importance of health care professionals attending to anxiety disorders, in order to plan for service member needs, develop preventative interventions, address early detection, and deliver treatments to improve combat readiness.

Identifying risk factors for suicidal ideation across a large community healthcare system

BACKGROUND

Suicide is the tenth leading cause of death in the United States. Several studies have leveraged electronic health record (EHR) data to predict suicide risk in veteran and military samples; however, few studies have investigated suicide risk factors in a large-scale community health population.

METHODS

Clinical data was queried for 9,811 patients from the Penn Medicine Health System who had completed a Patient Health Questionnaire-9 (PHQ-9) documented in the EHR between January 2017 and June 2019. Patient demographics, PHQ-9 scores, and psychiatric comorbidities were extracted from the EHR. Univariate and multivariable logistic regressions were applied to determine significant risk factors associated with suicide ideation responses from the PHQ-9.

RESULTS

One-quarter (25.8%% of patients endorsed suicide ideation. Univariate analysis found 22 risk factors of suicide ideation. Multivariable logistic regression found significant positive associations (Odds Ratio, (95% Confidence Interval)) with the following: younger ages less than 18 years: 2.1, (1.69, 2.60) and 19-24 years: 1.55, (1.29, 1.87)), single marital status (1.22, (1.08, 1.38)), African American (1.22, (1.08, 1.38)), non-commercial insurance (1.16, (1.03, 1.31)), multiple comorbidities (1 comorbidity (1.65, (1.32, 2.07); 2 comorbidities (2.07, (1.61, 2.64)), 3+ comorbidities (2.49, (1.87, 3.33))), bipolar disorders (Type I: 1.38, (1.14, 1.67) and Type II: 1.94, (1.52, 2.49)), depressive disorders (1.70, (1.49, 1.94)), obsessive compulsive disorder (OCD) (1.43, (1.08, 1.90)), and stress disorders (1.53, (1.33, 1.76)).

CONCLUSION

Community EHR information can be used to predict suicidal ideation. This information can be used to design tools for identifying patients at risk for suicide in real-time.

Abnormal night sleep duration and inappropriate sleep initiation time are associated with elevated anxiety symptoms in Chinese rural adults: the Henan Rural Cohort

Sleep problems have been demonstrated to cause mental symptoms, such as anxiety. However, research on the association of the night sleep duration and sleep initiation time on anxiety symptoms in rural China is still lacking. The current study, therefore, explored the independent and combined association of the night sleep duration and sleep initiation time on anxiety symptoms. This study included 28, 054 participants from the Henan Rural Cohort. Sleep was measured using the Pittsburgh Sleep Quality Index (PSQI). Anxiety was assessed by the two-item Generalized Anxiety Disorder scale (GAD-2). Multivariable logistic regression models and restricted cubic spline with anxiety symptoms as a dependent variable were fitted. Among the participants in this study, 11, 209 (39.96%) were males, and 16,845 (60.04%) were females, 1574 (5.61%) had anxiety symptoms. Both shorter and longer night sleep duration were significantly related to elevated prevalence of anxiety symptoms. Extreme sleep initiation time was also significantly associated with elevated anxiety symptoms. Additionally, night sleep duration and sleep initiation time had a combined effect on the prevalent anxiety symptoms. In conclusion, there was a dose-response association of night sleep duration and sleep initiation time with anxiety among Chinese rural population. Moreover, they might jointly increase the odds of prevalent anxiety.

Acute Shame Predicts Urges for Suicide but not for Substance Use in a Veteran Population

OBJECTIVE

There is an urgent need to identify ways to reduce rates of suicide among Veterans with a substance use disorder. Since co-occurring disorders can make diagnosis and treatment complex, it is useful for the mental health field to examine common factors that may underlie both problems. One common factor that underlies both substance use and suicidal behavior is shame. This brief report presents data collected in an experimental study examining shame as an acute risk factor for suicide and substance use in Veterans.

METHOD

Thirty-eight Veterans admitted to an inpatient Veterans Affairs Medical Center unit with suicidal ideation completed measures on depression, hopelessness, addiction, and suicidality. Participants were randomized to either a shame mood induction group or a control group, and completed pre- and postexperiment measures on urges for suicide, urges for substance use, and level of shame.

RESULTS

Results indicate that an acute increase in shame resulted in an increase in an urge for suicide, but was not associated with changes in urges for substance use.

CONCLUSIONS

Acute feelings of shame may be a risk factor for increases in suicidal ideation. Limitations and suggestions for future directions are discussed.

The future disposition Inventory-24: reliability and validity estimates in a large sample of Chinese University students

BACKGROUND

This study was designed to assess the factor structure, internal consistency reliability, and preliminary psychometric properties of the Chinese version of the Future Disposition Inventory-24 (FDI-24) in a large sample of Chinese university students.

METHODS

We translated the English version of the Future Disposition Inventory-24 (FDI-24) into Chinese and examined its factor structure, estimates of internal consistency reliability, and psychometric properties in a representative sample of university students. In particular, students (N = 2,074) from two universities in Shandong Province in China were identified using the multi-stage stratified sampling method. In addition to the FDI-24, we collected preliminary data using self-report instruments that included the Beck Hopelessness Scale (BHS) and a general sociodemographic information questionnaire.

RESULTS

The results of the internal consistency reliability estimates were adequate regarding the scores on the three FDI-24 subscales: Cronbach's alpha = .89-.97, Omega total = .85-.96, Revelle's Omega total = .88-.96, the greatest lower bound (GLB) = .89-.96 and Coefficient H = .86-.94. Bivariate correlation analyses showed evidence for criterion and discriminant validity. The 3-factor oblique-Geomin-rotation solution accounted for 62.92% of the total variance in the exploratory factor analysis (EFA). The exploratory structural equation modeling (ESEM) result showed that the 3-factor model provided adequate fit statistics for the sample data: the robust comparative fit index (R-CFI) was .959, robust Tucker Lewis index (R-TLI) was .946 and robust root mean square error of approximation (R-RMSEA) was .090.

CONCLUSION

The FDI-24 has a satisfactory factor structure, reliability estimates, and satisfactory evidence of concurrent validity estimates for students with different demographic and cultural backgrounds. The FDI-24 holds promise for use in future investigations with Chinese students.

Military service and crime: new evidence

BACKGROUND

Evidence indicates that a substantial proportion of military personnel are involved in high-risk and antisocial behaviors that place them at jeopardy for criminal justice system involvement. However, prior research on military service and crime has disproportionately focused on veterans from the Vietnam War era (1955-1975), and has tended to focus on either current or former military members.

METHODS

This study employed data from a population-based study (i.e., National Study on Drug Use and Health [NSDUH] between 2002 and 2014). It systematically examines the prevalence of self-reported antisocial behaviors, criminal justice system involvement, and substance abuse among the US civilian population and military service members, including reservists (n = 2206) and those who reported having been separated or retired from military service (n = 20,551). These factors are further examined across the developmental spectrum of adulthood (ages 18-34, 35-49, and 50-64).

RESULTS

Results showed that military members were more prone to lifetime arrests and overall substance misuse. However, additional findings emerged suggesting that, while the military population overall seems to be positively associated with higher criminal activity than that found in the civilian population, these findings were based on a specific subgroup of the veteran population. This subgroup is comprised of individuals who likely did not fit in with the military culture and were discharged from the military early in their careers.

CONCLUSION

Additional research on identifying this subgroup of military members is encouraged to better concentrate on prevention and treatment measures.

Long-Term Suicide Risk in Anxiety-The Lundby Study 1947-2011

The objective of this study was to calculate the long-term risk of accomplished suicide in anxiety disorders, and to compare this with a healthy population. The Lundby Study is a prospective, longitudinal cohort study on a population of 3,563 subjects. Between 1947 and 1997, anxiety disorders were diagnosed in 300 subjects. Up to 2011 there were 68 suicides in all. The suicide risk was 3.3% for anxiety. For only anxiety, risk was increased (p = 0.008), but other diagnoses had a higher risk (p = 0.0001) compared with no diagnosis. Mean time from onset to suicide was 27 years. Risk of suicide in anxiety disorders seems elevated at an intermediate level. Suicide often occurs many years after onset of the disorder.

Anxiety and its disorders as risk factors for suicidal thoughts and behaviors: A meta-analytic review

Suicidal thoughts and behaviors are highly prevalent public health problems with devastating consequences. There is an urgent need to improve our understanding of risk factors for suicide to identify effective intervention targets. The aim of this meta-analysis was to examine the magnitude and clinical utility of anxiety and its disorders as risk factors for suicide ideation, attempts, and deaths. We conducted a literature search through December 2014; of the 65 articles meeting our inclusion criteria, we extracted 180 cases in which an anxiety-specific variable was used to longitudinally predict a suicide-related outcome. Results indicated that anxiety is a statistically significant, yet weak, predictor of suicide ideation (OR=1.49, 95% CI: 1.18, 1.88) and attempts (OR=1.64, 95% CI: 1.47, 1.83), but not deaths (OR=1.01, 95% CI: 0.87, 1.18). The strongest associations were observed for PTSD. Estimates were reduced after accounting for publication bias, and diagnostic accuracy analyses indicated acceptable specificity but poor sensitivity. Overall, the extant literature suggests that anxiety and its disorders, at least when these constructs are measured in isolation and as trait-like constructs, are relatively weak predictors of suicidal thoughts and behaviors over long follow-up periods. Implications for future research priorities are discussed.

Predictors of Suicidal Ideation Across Deployment: A Prospective Study

OBJECTIVE

Concurrent and prospective predictors of suicidal ideation were examined in a sample of 318 United States Air Force Security Forces across a 1-year deployment in Iraq and 6- to 9-month follow-up.

METHOD

Participants included 294 male and 24 female Airmen ranging in age from 18 to 46 years, predominantly (67%) Caucasian. Measures included self-reports of postdeployment suicidal ideation, posttraumatic stress and depressive symptoms, alcohol use, combat experiences, relationship distress, social support, and postdeployment readjustment.

RESULTS

Problem drinking before deployment prospectively predicted postdeployment suicidal ideation in univariate analyses. Depressive symptoms and problem drinking were significant independent predictors of postdeployment suicidal ideation. Findings demonstrated a ninefold increase in suicidal ideation among service members with even mild depressive symptoms if moderate problem drinking was also present.

CONCLUSIONS

Predeployment problem drinking may serve as a modifiable target for early intervention of suicidal ideation. Findings illuminate the compound risk of comorbid depressive symptoms and moderate problem drinking in predicting suicidal ideation.

Understanding the elevated suicide risk of female soldiers during deployments

BACKGROUND

The Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) has found that the proportional elevation in the US Army enlisted soldier suicide rate during deployment (compared with the never-deployed or previously deployed) is significantly higher among women than men, raising the possibility of gender differences in the adverse psychological effects of deployment.

METHOD

Person-month survival models based on a consolidated administrative database for active duty enlisted Regular Army soldiers in 2004-2009 (n = 975,057) were used to characterize the gender × deployment interaction predicting suicide. Four explanatory hypotheses were explored involving the proportion of females in each soldier's occupation, the proportion of same-gender soldiers in each soldier's unit, whether the soldier reported sexual assault victimization in the previous 12 months, and the soldier's pre-deployment history of treated mental/behavioral disorders.

RESULTS

The suicide rate of currently deployed women (14.0/100,000 person-years) was 3.1-3.5 times the rates of other (i.e. never-deployed/previously deployed) women. The suicide rate of currently deployed men (22.6/100,000 person-years) was 0.9-1.2 times the rates of other men. The adjusted (for time trends, sociodemographics, and Army career variables) female:male odds ratio comparing the suicide rates of currently deployed v. other women v. men was 2.8 (95% confidence interval 1.1-6.8), became 2.4 after excluding soldiers with Direct Combat Arms occupations, and remained elevated (in the range 1.9-2.8) after adjusting for the hypothesized explanatory variables.

CONCLUSIONS

These results are valuable in excluding otherwise plausible hypotheses for the elevated suicide rate of deployed women and point to the importance of expanding future research on the psychological challenges of deployment for women.
