Are Gambling Problems More Common Than Drinking Problems in Adults?

by: Institute Staff | Mar 28, 2011

Stories about a recent study on gambling and alcohol use across the lifespan have begun popping up around the Internet with contradictory titles like “Gambling Problems Are More Common Than Drinking Problems, According To First-Of-Its-Kind Study” and “Are Gambling Problems More Common than Drinking Problems? Maybe Not”. The study, published in the Journal of Gambling Studies, is from the Research Institute on Addictions at the University at Buffalo, N.Y. (Welte, Barnes, Tidwell, & Hoffman, 2010). The study is primarily about patterns of gambling behavior across the lifespan compared to patterns of alcohol use and other potentially problematic behaviors, but the researchers also report findings that compare gambling and alcohol problems in the general population. These differences have caused some confusion on the issue.

The researchers state that “after age 21 problem gambling is considerably more common than alcohol dependence” (Welte et al., 2010, p. 57). At first, this statement seems to be at odds with previously published research. It is generally accepted that the rate of alcohol dependence is about double that of pathological gambling (Keyes, Geier, Grant, & Hasin, 2009; Stucki & Rihs-Middel, 2007).

However, a look at the definitions the researchers use explains the apparent discrepancy. The “problem gambling” they refer to is defined as anyone who endorses three or more items on the Diagnostic Interview Schedule (DIS) for the DSM-IV,the handbook for psychiatric disorder in the United States (American Psychiatric Association, 1994). This is a standard way to define problem gambling, a less severe form of the disorder, with pathological gambling being defined as endorsing “five or more criteria,” as the researchers state in the methods section of the paper (Welte et al., 2010, p. 53). The researchers found this broadest definition of problem and pathological gambling to be between 3 and 5 percent for people ages 22 to 60. This is in line with previous research on the subject.

The confusion comes from comparing this broadest definition of disordered gambling with a narrow definition of alcohol disorders. Like gambling disorders, alcohol use disorders are categorized by severity. Alcohol abuse is the less severe disorder while alcohol dependence is the most severe, and the two together are called alcohol use disorders. One of the largest studies of alcohol use disorders is the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) (Hasin, Stinson, Ogburn, & Grant, 2007). The NESARC is a nationally representative survey consisting of face-to-face interviews with more than 43,000 Americans. The NESARC found that people ages 30 to 44 suffered from alcohol abuse at 6 percent and alcohol dependence at 3.8 percent, for a total alcohol use disorder rate of 9.7 percent. When the rate of 9.7 percent is compared with the combined rate of problem and pathological gambling in the Welte et al. study, about 4.5 percent, we find that alcohol use disorders are about double gambling disorders. Note that Welte et al. divided their age groups differently, so this analysis combines the 31-40 and 41-50 groups.

The researchers at the University of Buffalo did not discuss the discrepancies in definitions in their study. However, their larger discussion of alcohol use and gambling across the lifespan is an interesting one that certainly deserves more in-depth study.
