This research examined the link between the DSM-5 symptoms of gambling disorder (GD) and suicide. The researchers recruited 142 patients who sought treatment for their GD at a treatment centre in South Korea. The results revealed that the number of symptoms was higher among those who reported suicidal ideation and past suicide attempts. Those with suicidal ideation were more likely to report negative impacts on life and ‘bailouts’ (i.e., seeking help for financial problems). Those with past suicide attempts were more likely to report preoccupation and gambling for relief from problems and bad moods. Bailouts remained a risk factor for suicidal ideation even after taking into consideration depressive mood. Gambling for relief remained a risk factor for past suicide attempts even after taking into consideration depressive moods.
