There has been very little research into this possibility. This study aimed to investigate the characteristics associated with problem gambling in a large population-based study in England, with a particular focus on IQ.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291713002195_sec_a2\" sec-type=\"methods\"><jats:title>Method<\/jats:title><jats:p>The Adult Psychiatric Morbidity Survey (APMS) 2007 comprised detailed interviews with 7403 individuals living in private households in England. Problem gambling was ascertained using a questionnaire based on DSM-IV criteria. Verbal IQ was estimated using the National Adult Reading Test (NART). Confounders included socio-economic and demographic factors, common mental disorders, impulsivity, smoking, and hazardous drug and alcohol use.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291713002195_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>More than two-thirds of the population reported engaging in some form of gambling in the previous year, but problem gambling was rare [prevalence 0.7%, 95% confidence interval (CI) 0.5\u20131.0]. The odds of problem gambling doubled with each standard deviation drop in estimated verbal IQ [adjusted odds ratio (OR) 2.1, 95% CI 1.3\u20133.4, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.003], after adjusting for other characteristics associated with problem gambling including age, sex, socio-economic factors, drug and alcohol dependence, smoking, impulsivity and common mental disorders.
