Veterans and suicides?

Claude Fischer, professor of sociology | February 1, 2016

The “wave of veteran suicides,” in the words of The New York Times editors last year, seems to cap the traumas that the vets have borne in service to the nation. It turns out, however, that actually establishing that there is a connection between military service and suicide is difficult. It may take years more research to fully understand its personal toll. The “Forever War” of an earlier generation, Vietnam, produced a particularly strong debate about serving and suicide.

While the tragic consequences seemed clear to some, the data have been much more opaque. The veteran-suicide connection was, as a recent article describes, also opaque a century ago when the veterans in question had served in the Civil War.

Vietnam and since

Advocates for Vietnam vets are convinced that their suicide rate has been abnormally high and, moreover, that the Defense Department has suppressed the true count (see, e.g.,here; here). Scholars have argued over the evidence, some finding that vets were no likelier than other men of their age and background to commit suicide. (I refer to men because women took on roles closer to combat only in recent years. Note, also, that  the attention here is to suicides by veterans, not to suicides by on-duty servicemen.)

At least two technical issues complicate getting a satisfying answer. One is establishing an accurate count of suicides. Official statistics underestimate suicides because authorities often label ambiguous cases such as car crashes or drug overdoses as accidents, sometimes to spare the feelings of the family. It is hard to know whether such undercounting is more or less common for veterans than for others.

The other issue is the “selection” effect. The men who ended up in the military – even when there was a draft – and the men who, once in the military, ended up in Vietnam, much less those who ended up in combat, were not a random draw of the population. Even before entering the military, they differed in systematic ways from non-vets.[1] So, if the raw suicide rates are higher for vets, that alone cannot establish cause and effect.

How, one might ask, could war service not increase the propensity to suicide? It may be that people generally recover from the trauma of combat. Or, while service may be traumatizing for some people, perhaps for just as many others the military experience builds strength and confidence. Indeed, there is some evidence that the military tends to select and keep those who are “healthy warriors,” and that servicemen generally fare better, at least barring combat, than those who never served.

One effort to assess the veteran-suicide connection was a study reported in a community health journal in 2007. It drew on a national health survey conducted in the 1980s and 1990s of hundreds of thousands of Americans. The researchers looked up the respondents in the National Death Index to see which of the interviewees were later recorded as having died by suicide.

After adjusting for all sorts of other differences among the men (age, race, marital status, education, health, etc.), the researchers found that those who had reported serving on active duty were about twice as likely as otherwise similar non-vets to have later committed suicide.[2] The vets were not, the researchers noted, more likely than to die than the non-vets for other reasons.

However, in 2008, a “blue ribbon” Defense Department commission (pdf) concluded that various studies on the veteran-suicide connection were, in the end, mixed. Its report pointed to several technical problems in correctly ascertaining that relationship.[3]

A May, 2012 paper published in the American Journal of Public Health (AJPH) challenged the 2007 analysis. These authors used the same health survey and national death data as the previous ones had, extended a few years. With a slight adjustment in procedures, they found that veterans were likelier to commit suicide by firearm than were non-veterans – veterans are likelier to own firearms – but that overall the difference between vets and non-vets was statistically marginal, perhaps a 10 percent elevated rate.

Although they concluded that there was no causal effect on suicide of being a veteran, there remained reason to suspect that there was such an effect.[4] Another analysis, reported in the same issue of the journal, using somewhat different data, reported especially elevated suicide rates among young veterans. Controversy ensued in this issue and then in the May, 2014 issue of the AJPH. It seems a muddle.

Recognizing that there are prior differences between veterans and non-veterans that may not be adjustable statistically – in the Vietnam era, for example: feelings about the war, or access to a doctor who could provide a health deferment, or being a criminal defendant who was offered the option of enlisting rather than going to jail – some researchers have sought to use a proxy for having served that is uncontaminated by a selection effect: men’s Vietnam War draft lottery number, which was randomly based on birthdays.

The lower the lottery number for his birth date, the higher the chance a man had of being drafted and of serving in Vietnam, whatever his personal characteristics or inclination. (Draft number serves as an “instrumental variable” in econometrics lingo.)

For example, a 2102 article in Demography assesses whether men born between 1950 and 1952 with draft-eligible birthdays (low lottery numbers) ended up years later with higher than expected suicide death rates. The answer is no. But it is not clear whether lottery number is really a good proxy for military service during the Vietnam War. In an earlier study, two economists showed that the connection between draft lottery number and actual service, though real, is probably not strong enough to use the number as a solid proxy for being in the military.[5]

Cannot this question be settled? A few studies of Vietnam vets suggest a clarification: that the key is not being a veteran but being a combat veteran. A 1996 paper reported that Vietnam army vets who had been wounded more than once were likelier than other vets to have later died by suicide. A 2002 article compared thousands of pairs of twins who had both served during the Vietnam era. The one who had experienced serious combat was likelier to say that he had considered suicide than the twin who had not seen major combat. Finally, a 2012 report found that Vietnam vets who reported having killed someone in Vietnam more often reported having considering suicide than ones who had not killed.[6]

It would appear that combat experience, not military experience, did raise the risk of suicide, at least for those who served in Vietnam. That it took time to see this price of service clearly is not new. This research forms a context for a 2015 study of suicide among veterans of the Civil War.

Civil War

Historian Larry Logue, in the Journal of Social History, uncovers and explores the records of suicides in Massachusetts from 1860 to 1900. One discovery is that the suicide rate of (white) Civil War veterans was about 50 percent higher than that of non-veterans.

Another was that, early on, the news stories about suicides – and suicides were popular grist for the press – tended to ignore that part of the decedents’ situations. They typically failed to mention that the victim had been a veteran and typically explained their suicides as the consequences of insanity, depression, economic misfortune, and the like.

Toward the end of the 19th century, however, press coverage more often mentioned military service and more often ascribed the suicides to the physical or mental toll of the Civil War. It was only later, Logue argues, that the media and the public were willing to revisit the war experience with more open eyes, willingness to acknowledge its tragedy, and empathy for its long-term victims.

The story of the veteran-suicide connection for Vietnam sounds similar.

[1] Disclosure: I had a student deferment for a few years of the war and then drew a high draft number. I passed an Army physical in Boston but was never called.

[2] The study did not take into account that, if the way military experience eventually leads to suicide is through a series of difficulties (e.g., divorce, unemployment, ill health), then controlling for those factors would underestimate the extent to which service promotes suicide.

[3] For example: Some men report themselves as veterans even if they had washed out of basic training; a higher proportion of veterans’ suicides may be accurately reported because veterans are likelier than other suicides use firearms, rather than the more ambiguous means, to take their lives.

[4] Overall, unadjusted, the odds ratio for risk of suicide between self-reported veterans and other men was 1.36. This study adjusted only for year, age, and race, and came up with an adjusted OR of 1.11 (95% CI: 0.96, 1.29). But when the researchers applied similar procedures to the same years as the 2007 study, they found a significant veterans effect. The claim of nil results is not that definitive.

[5] For men born from 1950 to 1952, about 30 percent of those who were draft-eligible by lottery ended up serving versus about 15 to 20 percent of those with high lottery numbers (Figure 2). That’s a notable difference, but by far most men in both groups did not serve, which makes inference from birthday to service quite fuzzy.

[6] Two methods points: Actual reported suicide attempts were so few in the samples for the last two studies that effects on attempts could not be reliably estimated, though the trends were consistent. And: These studies also control for all sorts of presumably intermediate conditions such as PTSD and substance abuse. Properly done, the estimates of combat’s effects should have included indirect effects through those conditions and would – presumably – result in stronger findings.

Comments to “Veterans and suicides?

  1. A couple of you guys hit on my thoughts. I’m a cold war 84-90 Army pog. Been thinking about it since I left. No worries I’d never do that to my family. I don’t know the stats. What I know is at 18 yrs old i and my unit were changed forever for good and bad. Along with patriotism, disapline, motivation, and strength and bravery being embedded into a bunch of clueless kids came the usually unmentioned necessities of making warriors. We were taught to kill and if it came to it die for the mission and the guy next to you yelling buddy ready. I believe Armies need to be brutally emotionless when it time to fight. Leaving that brotherhood and being dumped civilization with fake ty for your service is what kills a warrior. None military people can’t comprehend who we are and why we’re so different so they try patriotism or being jerks. Most I know don’t want credit but can’t stand seeing other soldiers and vets not receive credit. Remember the we are killers Part now. Most see right through disingenuous patriotism and are offended for all others in our club. The jerk part is worse. We have the most important part of defending our country permanently embedded in us. That part is “will”. We know we will fight and win. The reality of ability doesn’t need to be equated because we “will”. So we are faced with go to jail for protecting honor or walk away. Most make the right choice. We say ty to those thanking us and if possible walk away from the jerks. Both still leave a soldier even more empty inside. Another key issue is what u do after ETS. I was offered and accepted a lifetime middle class union job at the post office. I later realized federal employment is hell for a warrior but to late the paycheck traps most. I’ve had to deal with several federal agencies and they’re all pretty close to the same. The VA is included but I feel the most shameful of all the agencies. It’s existence is to help soldiers but like the other agencies with ignored piles of rules, regulations, and CFRs the VA not only fails but lures soldiers in with the promise of helping then fights everthing they talk the soldier into asking for. Most of the help they offer never improves anything. The obvious big ones are health and money (disability). Follow everything printed in the VA CFR and you’ll quickly learn all VA doctors are afraid of giving true health assistance. Most soldiers wouldn’t bother going to the VA with a problem non military related but the all doctors are terrified of typing in “began in service” because soldiers can get free health and disability money from it. I’ve said many times against my own interests “close the USPS and the VA. With the mission of serving both agencies along with others destroy our veterans leaving them feeling more rejected by society. I apologize for the rant. The bottom line is after leaving the Army I’ve never been able to feel any purpose or fit that’s even close to what I learned at 18. Great family, great job for most, spoiled rotten American. Whatever the percentage that do the deed most don’t. We may suffer for not getting to fight. We may suffer for having to fight. Many will never fit in. Thanks for thanking us. You are an idiot if you don’t like us for not letting you push us. Stop hating us because of whatever politics or ego u have. Just leave us alone to live out our time. Oh yeah and feel free to call us up young and old when the friendly freedom bus is threatened from the rest of humankind. Again sorry my mind never stops lol

  2. A chapter of Vietnam Veterans of America Chapter1068 – We are registered with the Vietnam Veteran of America, in Somerdale, New Jersey. We provide assistance for Vietnam Veterans in their search of Health, Medical, Employment and other issue’s.

  3. A dozen peer reviewed studies in the US and UK show combat veterans do not commit suicide at higher rates, nor commit violent crime, nor domestic violence at higher rates than the general public in the same demographic cohorts.

    The entire elevation of those rates is solely among veterans who never saw combat.

  4. The emotions of killing run deep. If we believe we evolved from an impersonal mass, then killing or healing share the same meaninglessness. But our creator placed eternity in our hearts, making us aware of the folly behind killing. Combat kills both the killed and killer. If you chat about fighting today with combat veterans of the Pacific War (1942-1945) many begin to cry—even 73 years after the end. Our design does not include killing as a normal purpose.

  5. I recently attended an art exhibit with paintings and collages based upon Athens, Ohio newspapers from 1968 and photos taken by Ronald Haeberle, who was the army photographer at My Lai. The artist [Dirk Leach] claimed that “more Vietnam vets have killed themselves than the 60,000 killed in action.” I was suspicious of this figure, and your article provides specific reasons to support my doubt. His claim should be hedged with “perhaps” and “it’s complicated.”

  6. There are many reasons veterans commit suicide. People commit suicide every day, but veterans are a special case. I do not think it matters whether or not a veteran has been in combat. It’s the training that creates the problem. My belief is that if we can train people to kill, we can untrain them or deprogram them and save some veterans, families and communities the trauma that veterans suicides create.
    My situation was unique. When I told my English teacher in high school that I was going to West Point, he tried to talk me out of it. When I decided to quit in my second year he was one of the people who talked me into staying. I graduated, went to airborne, ranger and artillery officers’ training and did one combat tour. This teacher and I corresponded through four years of West Point, four years of the Army, and two years of graduate school. As I was leaving grad school a box arrived with 10 years of my letters enclosed and a brief note on top which read, “Now you tell me that you weren’t brainwashed.”
    It took a while and good friends to undo the damage. I am now committed to stopping veterans suicides.
