“…Finally, present results show that the interactions between TBI burden and memory/processing speed remained significant predictors of SI even when accounting for psychiatric and postconcussive symptom severity. Previous research has consistently demonstrated that psychiatric distress is one of the strongest predictors of suicidality (Brown et al, 2000; Jakupcak et al, 2009; Pietrzak et al, 2010; Zimmerman et al, 2015), including in active duty and veteran samples with a history of TBI (Brenner et al, 2011; Bryan & Clemans, 2013); however, our findings demonstrate that other nonemotional variables, specifically TBI-related and cognitive factors, together uniquely contribute to increased suicide risk, above and beyond psychiatric factors. As such, the present results may hold important treatment implications; cognitive training or interventions that simultaneously target both cognitive dysfunction and psychiatric distress may be most appropriate for this vulnerable group.…”

Objective: Suicidal ideation (SI) is highly prevalent in Iraq/Afghanistan-era Veterans with a history of mild traumatic brain injury (mTBI), and multiple mTBIs impart even greater risk for poorer neuropsychological functioning and suicidality. However, little is known about the cognitive mechanisms that may confer increased risk of suicidality in this population. Thus, we examined relationships between neuropsychological functioning and suicidality and specifically whether lifetime mTBI burden would moderate relationships between cognitive functioning and suicidal ideation. Method: Iraq/Afghanistan-era Veterans with a history of mTBI seeking outpatient services (N=282) completed a clinical neuropsychological assessment and psychiatric and postconcussive symptom questionnaires. Results: Individuals who endorsed SI reported more severe PTSD, depression, and postconcussive symptoms and exhibited significantly worse memory performance compared to those who denied SI. Furthermore, mTBI burden interacted with both attention/processing speed and memory, such that poorer performance in these domains was associated with greater likelihood of SI in individuals with a history of three or more mTBIs. The pattern of results remained consistent when controlling for PTSD, depression, and postconcussive symptoms. Conclusions: Slowed processing speed and/or memory difficulties may make it challenging to access and utilize past experiences to solve current problems and imagine future outcomes, leading to increases in hopelessness and SI in Veterans with three or more mTBIs. Results have the potential to better inform treatment decisions for Veterans with history of multiple mTBIs.

“…Las anteriores cifras muestran un panorama de las investigaciones en el contexto latinoamericano sobre las variables cognitivas asociadas al riesgo suicida como la depresión (42), neuroticismo (43) e inflexibilidad cognitiva (44). Estos modelos han obtenido evidencia en muestras conformadas en países como Estados Unidos, en especial en personal de las fuerzas armadas, en donde se han reportado relaciones entre IS, síntomas depresivos, estrés postraumático y género (45,46). Sin embargo, la evidencia con muestras latinas o locales ha sido escasa.…”

Objetivo: establecer la relación entre ideación suicida, desesperanza, tríada cognitiva negativa y depresión, como evidencia del modelo cognitivo del riesgo suicida. Método: estudio empírico-analítico con diseño descriptivo, correlacional y comparativo. Las variables fueron medidas con los inventarios BDI-II, PANSI e ITC y la escala BHS. La muestra final estuvo constituida por 90 personas de ambos sexos, con una media de edad de 24,2 años (DT = 8,65 años) pertenecientes a diversos niveles socioeconómicos, con estudios universitarios, principalmente. Resultados: se encontraron correlaciones estadísticamente significativas entre ideación suicida, desesperanza, depresión y la tríada cognitiva negativa. Las diferencias fueron significativas entre los grupos depresivos y no depresivos, con grandes efectos para las tres variables cognitivas. Interpretación y conclusiones: estos resultados constituyen nueva evidencia del modelo cognitivo planteado acerca de la relación entre las variables depresión, tríada cognitiva negativa, ideación suicida y desesperanza, tal como se ha propuesto en distintas revisiones sobre cognición negativa y suicidio. Se analizaron las limitaciones del estudio en cuanto el reducido tamaño muestral y las diferencias entre sexos para depresión ante estresores específicos, y las variaciones por grupos de edades en el riesgo suicida de los jóvenes.

“…5,7 A rapidly growing body of research has identified risk factors associated with SI among service members, including sociodemographic characteristics (eg, being female, younger, older when first entering service, less educated, never married), 11 traumatic and life stressors (eg, adverse childhood experiences, military sexual trauma, combat exposure), [12][13][14][15][16] and MHDx (eg, current and lifetime posttraumatic stress disorder [PTSD] and major depressive disorder [MDD], problematic alcohol use). [17][18][19] However, it is not known whether these factors are differentially associated with SI during deployment, a time when soldiers are exposed to unique stressors and the context of threat may alter established mechanisms of suicide risk. Given the elevated risk of suicidal behaviors in middeployment, identification of risk factors during this period is critical.…”

Factors Associated With Suicide Ideation in US Army Soldiers During Deployment in Afghanistan

IMPORTANCE Understanding suicide ideation (SI) during combat deployment can inform prevention and treatment during and after deployment. OBJECTIVE To examine associations of sociodemographic characteristics, lifetime and past-year stressors, and mental disorders with 30-day SI among a representative sample of US Army soldiers deployed in Afghanistan. DESIGN, SETTING, AND PARTICIPANTS In this survey study, soldiers deployed to Afghanistan completed self-administered questionnaires in July 2012. The sample was weighted to represent all 87 032 soldiers serving in Afghanistan. Prevalence of lifetime, past-year, and 30-day SI and mental disorders was determined. Logistic regression analyses examined risk factors associated with SI. Data analyses for this study were conducted between August 2018 and August 2019. MAIN OUTCOMES AND MEASURES Suicide ideation, lifetime and 12-month stressors, and mental disorders were assessed with questionnaires. Administrative records identified sociodemographic characteristics and suicide attempts. RESULTS A total of 3957 soldiers (3473 [weighted 87.5%] male; 2135 [weighted 52.6%] aged Յ29 years) completed self-administered questionnaires during their deployment in Afghanistan. Lifetime, past-year, and 30-day SI prevalence estimates were 11.7%, 3.0%, and 1.9%, respectively. Among soldiers with SI, 44.2% had major depressive disorder (MDD) and 19.3% had posttraumatic stress disorder in the past 30-day period. A series of analyses of the 23 grouped variables potentially associated with SI resulted in a final model of sex; race/ethnicity; lifetime noncombat trauma; past 12-month relationship problems, legal problems, and death or illness of a friend or family member; and MDD. In this final multivariable model, white race/ethnicity (odds ratio [OR], 3.1 [95% CI, 1.8-5.1]), lifetime noncombat trauma (OR, 2.1 [95% CI, 1.1-4.0]), and MDD (past 30 days: OR, 31.8 [95% CI, 15.0-67.7]; before past 30 days: OR, 4.9 [95% CI, 2.5-9.6]) were associated with SI. Among the 85 soldiers with past 30-day SI, from survey administration through 12 months after returning from deployment, 6% (5 participants) had a documented suicide attempt vs 0.14% (6 participants) of the 3872 soldiers without SI. CONCLUSIONS AND RELEVANCE This study suggests that major depressive disorder and noncombat trauma are important factors in identifying SI risk during combat deployment.
