Testing NLCLiP: validation of estimates of rates of non-problematic and problematic gambling in a sample of British schoolchildren.

This paper reports on the results of applying a short screen for problem gambling, called NLCLiP, to a national sample of 8,958 British schoolchildren under the age of 16. It shows that, in its current form, NLCLiP can, with reasonable accuracy, be employed to estimate the rate of prevalence of problematic and non-problematic (i.e. gambling which does not lead to significant endorsement of DSM-IV-MR-J criteria) in a general population of children. However, NLCLiP does not reliably discriminate between problem and at risk gamblers. Moreover, it does not provide a reliable basis to identify cases of problem gambling. The main conclusion reached is that NLCLiP is a potentially useful tool for regulators to assess changes in the prevalence of problematic and non-problematic gambling among children over time.
