The Dutch instant lottery: prevalence and correlates of at-risk playing.

After a long and contentious political debate, the instant lottery was introduced in the Netherlands in 1994. One of the conditions for allowing the introduction was that an evaluation study should be conducted with regard to possible negative side effects of the instant lottery in terms of excessive playing or addiction. This article reports on the main results of this evaluation study. In a random sample of 4497 instant lottery players, at-risk players were differentiated from recreative players on the basis of level of involvement in the instant lottery, impaired control and the experienced negative consequences of playing. Of the sample, 4.1% could be classified as an at-risk player. Actual problems resulting from playing in the instant lottery were experienced by 0.7% of the players. At-risk players and recreative players did not only differ substantially in their playing behaviour, but also with regard to their socio-economic background, playing motivation, participation in other games of chance, and involvement in alcohol use and use of marijuana. To summarize, at-risk players were more likely to come from a poor socio-economic background, to play the instant lottery with a negative playing motivation, to be heavily involved in other forms of gambling, to have used marijuana and to drink alcohol excessively.
