Troubling Link Between Shoplifting and Suicide


Compulsive theft can lead to tragic results.

In the fall of 2011, 71-year old Julia Grodinsky of London was convicted of shoplifting ornamental crystals and sentenced to 18 months of probation. What made the case unusual was that Grodinsky had been convicted of shoplifting 63 times over the past 60 years. It seems likely that the elderly thief will continue to steal, given her history of poor decision-making.

In The Republic, Plato asked whether thieves are made or born. It’s an excellent question. Kleptomania, as it is traditionally called, is a special class of theft behavior: a chronic condition marked by compulsive stealing, often committed by people who could easily afford to buy what they steal. Brian L. Odlaug, a visiting researcher with the faculty of health and medical sciences at the University of Copenhagen, believes that kleptomania’s primary feature is that it strikes "people who had a good marriage, nice home, great job—and yet could not stop from stealing inconsequential items." It is a rare disorder, he notes, “while sociopathy and theft for gain are quite common.”

Curiously, the stealing never seems to be about money: The most recent study measuring income and shoplifting shows that people in the United States with incomes over $70,000 shoplift 30 percent more than those earning less than $20,000 a year. Today, compulsive shoplifting is labeled in the DSM-IV as an impulse control disorder. But historically this controversial diagnosis was variously seen as a biological disorder brought on by female agitation in department stores, an expression of repressed Freudian sexual desire, or a socially constructed disease that blossomed as a reaction to modernity. (A modest majority of shoplifters are women). Some observers in the early 20th Century even described kleptomania as a clever trick by psychiatrists to worm their way into law courts as purveyors of expert testimony.

Researchers today are more likely to be interested in what researcher Jon E. Grant, professor of psychiatry and behavioral neuroscience at the University of Chicago’s Pritzker School of Medicine, calls the “neurocognitive sequelae of shoplifting.” Grant and Orlaug are part of a group of psychiatric researchers who have been studying compulsive shoplifting for more than a decade. In the Archives of Suicide Research, lead author Odlaug documented abnormally high suicide rates among a group of 107 participants with kleptomania, 24.3 percent of whom had reported at least one suicide attempt. That figure is “6 to 24 times higher than in the United States general population,” according to the report—roughly similar to the rate of suicide attempts among patients with schizophrenic disorders. It is higher than the rate of suicide attempts reported in cases of major depressive disorder (16.5 percent).

93 percent of the participants reported that their suicide attempt “was directly or indirectly due to their kleptomania symptoms (e.g., shame over the behavior; legal or personal problems resulting from shoplifting).” Believed to be the first attempt to survey the association between suicide and shoplifting, the study also teased out a strong association between bipolar spectrum disorder and kleptomania symptoms. The odds of a past suicide attempt were five times greater for kleptomania subjects who had also been diagnosed with bipolar disorder.

“The suicide data are very troubling,” says Grant. “No one screens for this behavior, or when they are told about, most clinicians are very dismissive of it. There is definitely an attitude about kleptomania that it is more of a criminal problem.”

Dr. Howard Shaffer, an associate professor at Harvard Medical School and director of the division on addiction at The Cambridge Health Alliance, who was not involved in the research, says that the work “seems a reasonable heads-up for clinicians to consider the role of impulsivity and its impact on suicidal ideation and behavior; kleptomania is one kind of proxy for impulsivity.”

Compulsive shoplifting is commonly associated with substance abuse, pathological gambling, personality disorders, and bipolar syndrome, while sometimes overlapping with other impulse control disorders. Does it share common neurobiological deficits with these conditions? In a report published in Comprehensive Psychiatry, Grant and co-workers recruited young adults with no history of substance abuse or recognized mental health disorders, and ran them through a barrage of psychological testing. For the investigators, the important question was whether compulsive stealing is associated with certain neuropsychological dysfunctions that make kleptomaniacs different from other people. As it turned out, people with kleptomania risked more points in a test called the Cambridge Gambling Task, with results “similar to previous reports in people with damage to the ventromedial prefrontal cortices.” It was an admittedly small study, but the researchers think the results show that shoplifting is not just a rash act, but one associated with “specific decision-making and working memory deficits.”

A small neuromaging study published by Grant in 2006 showed evidence of “compromised white matter microstructure in inferior frontal areas,” suggesting to Grant that the frontal parts of the brain involved in decision making “may not be as healthy.” For his part, Odlaug thinks this finding may help explain “why so many patients report an 'irresistible' impulse to steal and a failure to inhibit that impulse.” Odlaug cautions that while deficits of executive functioning appear to be involved, “I think it is far too early to suggest cognitive predictors of kleptomania or other disorders characterized by impulse control deficits.”

Neuroscientist Marc Lewis, professor of human development and applied psychology at Radboud University in Nijmegen, The Netherlands, and author of Memoirs of an Addicted Brain, also questions whether sufficient data existed for asserting a link between impulsive behavior and working memory deficits. However, Lewis agrees that kleptomania “is seemingly its own disorder,” and “overlaps only partially with other psychiatric categories.”

Can kleptomania be cured, or treated successfully? In 2009, in an article for Biological Psychiatry, Grant and colleagues recorded the results of their work with 25 patients with kleptomania who were given high doses of naltrexone, a drug that blocks opioid receptors and is used to treat alcoholism and heroin addiction. All of the participants had been arrested, and had spent at least one hour per week stealing. The 8-week study, believed to be the first placebo-controlled trial of a drug for the treatment of shoplifting, resulted in a remission of symptoms in two-thirds of those on naltrexone. Says Odlaug: “With such a dearth of treatment data available, naltrexone appears to be the first-line treatment at this time. We have found that naltrexone at slightly higher doses is beneficial for a number of folks with kleptomania.” Some researchers are also investigating use of cognitive behavioral therapies.

“Kleptomania is thought of as a behavioral addiction within addiction circles,” Odlaug adds, while conceding that not everyone agrees with the concept of addiction to behaviors rather than substances. The neuropsychological approach to uncontrollable shoplifting as by no means unanimous. Writing in Global Society, Thomas Lenz and Rachel MagShamhrain argue that kleptomania is an “invented disease,” coinciding with the rise of the department store and strong beliefs in feminine “hysteria.”

“I think the general view,” says Grant, “is that criminal issues, or potential criminal issues, are not as biological as, say, depression. It then becomes a vicious cycle, as lack of research then continues to justify why people say it is not really biological or psychological.”

Lamentably, the connection between bipolar syndrome and shoplifting did not become apparent until recently, because people with bipolar symptoms are routinely ruled out of clinical studies of impulse control disorders. “Screening for people with co-occurring bipolar affective disorder and kleptomania is extremely important,” Odlaug stresses. “Especially in psychiatric settings where kleptomania and other impulse control disorders often go unrecognized by clinicians.”

Is Shoplifting the Opiate of the Masses?


Another look at "behavioral addictions" and the DSM-V.

The DSM-V, when it debuts it 2012, is set to replace the category of “Substance-Related Disorders” with a new category entitled "Addiction and Related Disorders."  Gambling is the only behavioral addiction currently recommended for inclusion, but some experts have set their sights on shoplifting—an activity that is even more difficult to picture as a legitimate addiction than gambling. Or is it?

Long before gambling was widely looked upon as an addictive disorder, compulsive shoplifting already had a name: kleptomania. The National Association for Shoplifting Prevention claims that about 9-10% of the population show a “lifetime prevalence” for shoplifting. This is remarkably similar to the percentages commonly bandied about for alcoholics, drug addicts, unipolar depressives,  compulsive gamblers, and compulsive overeaters.

A recent University of Florida survey pegged shoplifting losses, or “shrink,” in 2009 at more $11 billion annually. Plato, in The Republic, wanted to know whether thieves are made or born. It’s a good question. Curiously, the stealing doesn’t seem to be about money: The most recent study measuring income and shoplifting shows that Americans with incomes over $70,000 shoplift 30% more more than their fellow citizens earning less than $20,000 a year. And the actual items stolen by compulsive shoplifters often seem nonsensical, or even surreal. As director John Waters said of Pink Flamingos’ star and compulsive shoplifter Divine: “I saw him walk out of a store once with a chain saw and a TV.”

There is a definite “rush” to the act of stealing, writes Rachel Shteir in The Steal, her informative book about shoplifting. One shoplifter said it was equal to drugs but only lasted a few minutes—“And you’re back to yourself again. In your mind, you think, It was all for a stupid blouse, or stupid soap. For this, I risked everything.” Another source quoted in the book says, “I shoplifted every day, like someone with a drug addiction.”  Seconds before another women is arrested, she quizzes herself: “All she needs in the world is one crummy formal dress so why is there a blue silk jacket, one that she doesn’t particularly like, in her camera bag?” And a shoplifting Lee Grant says in the movie Detective Story: “I didn’t need it. I didn’t even like it.” The objects seem to lose their intrinsic value once they have been stolen, and the shoplifter must get high again with another theft.

If, as some neurobiological researchers insist, addictive disorders are not independent disorders, but outward manifestations of an underlying disease pathology called addiction syndrome, then the definition might be stretched to include gambling, shoplifting, and certain other “activity-based expressions of addiction.” Sometimes the alcoholic, the drug addict, the depressive, the compulsive gambler, and the obsessive overeater are all one and the same person. And drug addicts show a remarkably ability to substitute one drug for another. Perhaps a recovering cocaine addict might hope to assuage that sense of craving, of inchoate need, through excessive gambling. Or a shoplifter might use alcohol as a means of dampening the impulse to steal compulsively. While we don’t use the term kleptomania anymore, “shoplifting crops up as a symptom of many types of mental illnesses—bipolar disorders and anxiety disorders as well as substance abuse, eating disorders, and depression,” writes Shteir. Compulsive shoplifting, Shteir concludes, is “as difficult to stamp out as oil spills or alcoholism.”

For some, shoplifting brings a rush “similar to a cocaine or heroin high,” according to psychiatist Jon Grant at the University of Minnesota School of Medicine. To find out just how similar, psychiatrists there tried treating shoplifters with naltrexone, a drug that blocks opioid receptors and is used to treat alcoholism and heroin addiction. In 2009, in an article for the April issue of Biological Psychiatry, Grant and colleagues at the University of Minnesota School of Medicine recorded the results of their work with 25 kleptomaniacs, most of them women. All of the participants had been arrested for shoplifting at least once, and spent at least one hour per week stealing. The 8-week study is believed to be the first placebo-controlled trial of a drug for the treatment of shoplifting. In the April 10 issue of Science, Grant said that “Two-thirds of those on naltrexone had complete remission of their symptoms.”

That Pesky Gambling Question


The DSM-V is set to label problem gambling an addiction.

Nobody has ever bet enough on the winning horse.
Unknown wise person

I used to gamble. Back when I did, I was also an active alcoholic and a chain smoker. Camel filters, if you’re wondering. And we had a running joke, my wife and I, although the humor leaked out of it for her pretty quickly. We would breach the doors of the gambling palace, and plunge into the dark, icy interior of a casino at Las Vegas or Tahoe, and stand on the edge of the gaming room, taking it all in for a moment. “Ah,” I would say, surveying the roomful of cigarette smokers with drinks in their hands, making bets or hitting buttons at one o’clock in the morning, “my kind of people.”

Gambling can be defined as an activity in which something of value is put at risk in a situation where the outcome is uncertain.This post was chosen as an Editor's Selection for ResearchBlogging.org That’s really all there is to it. Howard J. Shaffer and Ryan Martin, whose article in the Annual Review of Clinical Psychology, “Disordered Gambling: Etiology, Trajectory and Clinical Considerations,” takes on all the interesting questions about gambling as an addictive disease, have chosen to favor the term “disordered gambling.” Just as there are divisions between alcoholic drinking, heavy drinking, and social drinking, there are similar states we can call pathological gambling, excessive gambling, and social gambling. On the problematic end of the scale, pathological or problem gambling has proven to be “a more complex and unstable disorder than originally and traditionally thought.” No kidding. Once the neurophysiology of the gambling state of mind came under scrutiny, the parallels with addiction cropped up so rapidly that investigators have been hard pressed to come up with suitable explanations for it all.

The new DSM-V proposes to shift pathological gambling from “impulse control disorder” to the new category of “addiction and related disorders.” So it’s a good time to rethink the question along with the psychiatric community.

In the traditional view, pathological gambling was a matter of exposure to the proper stimuli—it could happen to anyone. But as more and more gambling outlets and opportunities bloomed in Nevada, on reservations and riverboats, and in convenience stores, that view began to fall out of favor, because a funny thing happened. According to Shaffer and Martin, the prevalence of pathological gambling has remained stable over the past 35 years, even as opportunities to gamble have exploded. The lifetime prevalence rate of pathological gambling in the U.S. in the mid-1970s was 0.7%, say the authors, and by 2005, U.S. lifetime rates had actually fallen slightly, to 0.6% or less. Where was the concomitant explosion in the number of pathological gamblers?

Next, researchers got technical, wondering whether certain types of gambling, or certain types of gambling machines, were more “addictive” than others. They quickly ran into the same kind of trouble substance abuse researchers got into when they first tried ranking drugs according to strict hierarchies of addictiveness. In so doing, the staggering metabolic diversity of the human animal got lost in the shuffle, as did the fact that my metabolism and my behavior when taking drugs, or knocking one back, or losing money in a casino, is going to be different from yours.

Then came Internet gambling. In 1996, the first online casino to accept real money began operation, and by 2001, there were more than a thousand. Previously, researchers had to rely mostly on the time-honored but not always accurate system of self-reporting. If you ask people why they gamble, they tend to answer that they do it for the fun, the excitement, the challenge, and the chance to win some money. But what gamblers can’t recall very well are specific patterns of play over time that might benefit researchers. For example, in a 2009 study in which observers actually watched gamblers gambling, one long-standing observation from the self-report literature—gamblers become more liberal risk takers as they approach the end of a gambling session in a behavior called “chasing”—didn’t prove out. When researchers watched actual gamblers in action on the Internet, or playing lotteries, they found that problem gamblers in fact began betting more conservatively as they approached the end of their gambling, the authors write.

Another approach is to consider risk factors of all kinds—neurobiological, psychological, and social—and look for similarities between those for substance addiction, and those for “activity-based expressions of addiction.” The “syndrome model,” or what I usually call the umbrella model, derives from neurobiological research suggesting that “addictive disorders might not be independent: each outwardly unique addiction disorder might be a distinctive expression of the same underlying addiction syndrome…. The specific objects of addiction play a less central role in the development of addiction than previously thought….”

 All of this opens the door to some informed speculation about a broader range of disorders that may lurk beneath the umbrella of the addictive disease concept. Among these are such conditions as body dysmorphic disorder, bulimia, depression, and extreme PMS, which are all found more often in addict populations. In addition, impulsivity and low “harm avoidance” are behavioral traits often found in association with addiction. Shaffer and Martin call these “shadow syndromes,” and they are found to be associated with BOTH substance and behavioral addictions.

But what, exactly, is the high in gambling? The researchers believe that, “similar to ingesting stimulants, there is evidence that gambling is associated with autonomic arousal including elevated blood pressure, heart rate, and mood.” That's not very specific, and could also describe a craving for teddy bears. But recently, fascinating evidence of neurobiological influences on gambling arose when Parkinson’s’ patients on strong dopamine agonist treatments, with no history of gambling whatsoever, began behaving for all the world like pathological gamblers. I cannot imagine a better suggestion of neurogenetic involvement than this unexpected finding. Previous research had shown that dopamine-active drugs were capable of increasing the incidence of other addictions, too. Shaffer and Martin list compulsive eating, compulsive sexual behaviors, and compulsive shopping as activities that can also be boosted with dopamine agonists or diminished by lowering dopamine activity. 

And it does not strike me as surprising to learn that, yes, gambling problems tend to run in families, or that twins studies show that pathological gambling is higher among twins born to pathological gamblers than twins born to non-gamblers. It is the same evidence anyone can bring forth to bolster the argument for neurobiological influences on alcoholism, heroin addiction, and the like. “In sum” Shaffer and Martin conclude, “genetic influences might not determine the development of specific expression of addiction; however, genetics does influence the risk of addiction in general.”

If all of this is true, we should expect to see a corresponding connection between pathological gambling and substance abuse disorders. Some degree of overlap would be good evidence. And we have it in spades. Pathological gamblers are five and a half times more likely to have suffered from a substance abuse disorder. “75% of PGs (pathological gamblers) have had an alcohol disorder, 38% have had a drug use disorder and 60% have had nicotine dependence.” Also, “PGs are 4 times more likely than non-PGs to experience a mood disorder in their lifetime….”

So when I used to stand on the edge of the casino floor, as an alcoholic and a nicotine addict, casually calling those gamblers my kind of people, I think I was more right than I ever could have guessed.

Does all this mean that playing games on the Internet is an addictive behavior if making bets with real money is involved? The authors crunched the studies on that question, and discovered that maybe 1% of the Internet population has used the Internet for gambling purposes, and that “the case of Internet gambling provides little evidence that exposure is the primary driving force behind the prevalence and intensity of gambling…. The relationship between the extent of gambling ‘involvement’ is a better predictor of disordered gambling than any particular game that people play.”

By gambling involvement, the authors mean the number of different kinds of games a gambler plays. The more he or she plays, the more likely they are, or are likely to become, problem gamblers. However, it’s not hard to see where the online notion came from. Gambling folklore has always held that addiction is more of a risk with electronic gambling devices like slot machines and 5-Card Draw machines, than with traditional table games like roulette and craps. But the authors don’t find any convincing clinical evidence for this assertion at all. Internet gambling isn’t more addictive, and doesn’t confer any extra risk on people participating in other forms of gambling.

Here is a list of potential gambling behaviors that Shaffer and Martin believe might be risk factors to look out for in the development of problem gambling, with my additions in parentheses showing the connections to other drug addictions.

--Betting Intensity: how many bets per day. (With alcohol, how many drinks.)

--Gambling Frequency: number of gambling days (Number of drinking days.)

--Gambling Trajectory: tendency to increase the amount of wagered money. (Tolerance, in the case of drugs and alcohol.)

--Gambling Variability: deviation from consistent gambling pattern. (Inability to predict duration or outcome of drinking event.)

But if we list gambling under Addiction and Related Disorders, must we list all the possible variations on the theme—shopping and sex and all the rest, even though the picture is still fuzzy? No, the authors argue, we don’t. Not right this minute. But gambling is ready to join the roster. Shaffer and Martin would like to see their syndrome model of addiction used to identify “core features of addiction and then illustrate these with substance-related and behavioral expressions of this diagnostic class. Conceptualizing addiction this way avoids the incorrect view that the object causes the addiction and shifts the diagnostic focus toward patient needs.”
