This study explored subtypes of young adult gamblers based on their gambling involvement. It also tested how stable the subtypes were over a period of four years. Young Canadian gamblers could be grouped based on their degree of gambling activity involvement. The three subtypes included: low, moderate, and high involvement. Moderate gambling involvement was the riskiest and most stable subtype. It was linked with greater involvement in gambling and with other addictive behaviours. Young adults in the high gambling involvement subtype were the most likely to move into either the moderate or low gambling involvement subtype over time.
