Prevalence and correlates of gambling among 16 to 19-year-old adolescents in Norway.

There is evidence that young people are at high risk of developing gambling disorders. The prevalence and correlates of gambling among youth therefore merit closer study. During spring 2004, a sample of 1,351 boys and girls (aged 16-19 years) from 151 high-school classes (clusters) participated in an internet survey about gambling. The response rate was 69.8%. The instruments used in the survey were the Hospital Anxiety and Depression Scale, the Alcohol Use Disorders Identification Test and the Massachusetts Adolescent Gambling Screen, in addition to questions about demography. Controlling for the design effect, the estimated prevalence rate was 2.5% for pathological gambling and 1.9% for problem gambling. In all, 7.3% of the boys and 0.6% of the girls fulfilled the criteria for pathological or problem gambling. The results of item analysis of the DSM-IV subscale of MAGS provide support for differential item functioning between boys and girls. A multiple logistic regression analysis revealed that gender (male: OR = 9.09), depression (OR = 9.23), alcohol abuse (OR = 3.62), and dissociation (OR = 1.96) were related to problem and pathological gambling. These results support the view that gambling disorders are best understood as part of an addictive behavior spectrum (Jacobs, 2000).
