More than one in 10 Marines who deployed overseas reported having suicidal thoughts or plans to attempt suicide, according to a study looking at suicidal predictors.
The anonymous study of 1,517 active-duty Marines and sailors was conducted in 2006-2007. A wide cross-section of the Corps was represented, including the infantry, aviation and combat support communities. Most participants were male (93 percent) and from the junior enlisted ranks (E-1 to E-4). Nearly half had done more than one overseas deployment, but 11 percent were not combat-related.
The “most potent combination” for predicting suicidal thoughts and behavior, Thomsen said, was seen in Marines who experienced a great deal of combat and suffered from PTSD, depression or drug use. And those who reported both severe PTSD and high depression were “the people most at-risk for suicidal behavior,” she said.
Other findings include:
• Higher levels of combat exposure led to more PTSD symptoms and alcohol use, and these individuals reported they had less social support.
• Marines and sailors suffering from PTSD, depression and substance abuse “were more likely to report suicidal thoughts or plans,” she said.
• Those with strong social support “were less likely” to report suicidal thoughts or plans, she said.
• Deployment stressors, which can include worries about spouses and personal finances at home, or dangers such as heat and bugs in the war zone, were “significantly related,” Thomsen said.
• Pre-deployment trauma was a significant factor for those suffering from PTSD, depression, alcohol use or reporting poor social support, she said, but it wasn’t linked to those who used illegal drugs.
• One surprise was “alcohol problems did not emerge as a predictor of suicidal behavior,” Thomsen said. “This is really at odds with a lot of what we hear.”
• Another surprising finding: Lack of social support was “not a strong predictor,” she said, which is at odds with conventional thinking.
