The focus of this research is on what gamblers say about their behaviour during interview, implicit measures of that behaviour, and how traditional self-report questionnaires capture responses at the same time. The research explores what the relationships are between these methods, and if they change over time. It is anticipated that there will be significant relationships between elements of each of these methods that will add to the understanding and identification of problem gambling. It is expected that over time, as gamblers change their behaviours, these changes will be observed across the different methods of enquiry and relationships between different methods will be revealed.
