Подробное описание

Norsk Rikstoto (gambling monopolist in Norway providing horse gambling products) enforces registered play, hence all gambling transactions and outcomes of stakes of all customers are registered and stored for 5 years. Based on daily algorithms high risk gamblers are identified. Gamblers 18-50 years who for at least 5 of the last 30 days have been identified as high risk gamblers will according to a 1.5:1 ratio be allocated to a proactive call condition or to a control condition.

The call will be based on principles from motivating interviewing and will contain encouragements to alter gambling behavior (e.g., lowering loss limits). Primary outcome comprises theoretical loss (total bet x house advantage ((100% - payback%) / 100)). Secondary outcomes comprises total stakes made by the customer and loss percentage (proportion of stake that is lost). Baseline data comprises gambling behavior the 30 days before the call. Short-term effects comprise cumulative registered gambling behavior the first 90 days after the call whereas long-term effects consist of cumulative registered gambling behavior day 91-180 after the call. A random block design will be used where 15 eligible customers each week will be allocated either to the proactive call condition (n=9) or to the control condition (n=6).
