Effects of Proactive Call to Customers of Norsk Rikstoto (Horse Gambling Operator in Norway): A Randomized Controlled Study

The proactive call will be based on the principles of motivational interviewing. The content of the call comprises: 1) Asking the gambler/recipient to reflect on their gambling behavior, 2) providing to the gambler/recipient an overview of their gambling account and financial history, 3) offering to the gambler/recipient information about responsible gambling tools, such as setting lower limits, locking limits, taking a break, or self-exclusion, and 4) providing to the gambler/recipient information about relevant support services and the Gamban tool in cases where a need is expressed.
