This study examined whether gamblers’ motives or reasons for gambling remained stable over time. It also investigated factors associated with the stability of gambling motives. Participants were 2795 adult gamblers. Results revealed that only 22% of individuals remained with their primary motive for gambling over the 5-year period. This suggested that there was a great deal of fluidity across the motive categories. Most gamblers gambled for enhancement and financial reasons. Very few gamblers gambled for social, coping, or other reasons. Being resistant to gambling fallacies and engaging in more gambling activities predicted stability in gambling motives over time.
