The effect of loss-limit reminders on gambling behavior: A real-world study of Norwegian gamblers

Over the past two decades, problem gambling has become a public health issue and research from many countries indicates that a small but significant minority of individuals are problem gamblers. In Norway, the prevalence of problem gambling among adults is estimated to be just less than 1%. To help minimize the harm from gambling, the Norwegian government's gambling operator (Norsk Tipping) has introduced several responsible gambling initiatives to help protect players from developing gambling problems (e.g., limit-setting tools, voluntary self-exclusion, personalized feedback, etc.).

The aim of this study was to determine whether the receiving of personalized feedback exceeding 80% of a personally set monetary personal limit had an effect on subsequent playing behavior compared to those gamblers who did not receive personalized feedback.

Out of 54,002 players, a total of 7,884 players (14.5%) received at least one piece of feedback that they had exceeded 80% of their personal global monthly loss limit between January and March 2017.

Using a matched-pairs design, results showed that those gamblers receiving personalized feedback in relation to limit-setting showed significant reductions in the amount of money gambled.

The findings of this study will be of great value to many stakeholder groups including researchers in the gambling studies field, the gambling industry, regulators, and policymakers.
