The Effect of Research Compensation in the Form of Cheques on Gamblers' Cash-in Behaviour

A view that is commonly held by Research Ethics Board members is that offering money as research compensation has the potential to unduly influence or even coerce subjects into participating in studies. Because money is the core resource of gambling activity, gamblers with financial needs might show an increased propensity to take part in research that offers financial compensation. We hypothesized that pathological gamblers at electronic gambling machines in venues outside of casinos would tend to cash in their compensation cheque faster than non-pathological gamblers would. The current results support this hypothesis. It is therefore necessary to understand gamblers' motivations related to research activities and the ways in which the research context can sustain rational decision making when gamblers consider taking part in scientific studies.
