Researchers have used the common-sense model of self-regulation (CSM) to address physical illnesses and promote health behaviours. This study applies the CSM to understand how illness representations of GD are linked with gambling behaviours. The researchers used an online questionnaire to collect data. They found that perceived consequences of GD had a positive association with responsible gambling (RG) and a negative association with superstitious gambling behaviours. Also, emotional representations of GD were negatively associated with RG. But emotional representations had a positive association with superstitious gambling behaviours. The effects of perceived consequences and emotional representations on gambling behaviours were through positive gambling beliefs.
