People who gamble often engage in other addictive behaviours. In this study, the researchers examined co-occurring patterns of problem gambling and other addictive behaviours over time. They also examined demographic and psychological factors associated with these different patterns. The researchers analyzed data collected for a 5-year longitudinal study. They identified six co-occurring patterns of problem gambling and addictions. It was found that people who experienced a decrease in problem gambling did not ‘substitute’ this behaviour with other addictions. Rather, most people showed a pattern of decreases in both problem gambling and other addictions at the same time.
