Background: The research literature about the relationship between alexithymia, risky decision-making, and gambling severity has been contradictory and limited. Besides, there is no study on the mediating roles of self-compassion and emotion regulation in online gambling. Moreover, the role of these mediators in gambling frequency has not been studied. Thus, the present study aimed to investigate the relationship between alexithymia, risky decision-making, and gambling frequency by considering the mediating role of self-compassion and emotion regulation in online gamblers. Methods: A total of ۳۱۹ Iranians who gambled online at least once a week in the past three months were investigated using an online survey including Farsi Toronto Alexithymia Scale-۲۰ (FTAS-۲۰), Difficulties in Emotion Regulation Scale (DERS), and Gambling Disorder Screening Questionnaire-Persian (GDSQ-P). Statistical analyses were conducted by SPSS ۲۶.۰ for Windows. The relationships between the variables were analyzed using correlation analysis. In cases where significant relationships were observed, the hypotheses of the regression model were tested.Findings: The mean age of the participants was ۲۴.۶±۶.۰۶ and ۲۵۳ participants (۷۳.۹%) were male. Furthermore, no significant differences were observed between men and women in terms of risky decision-making (P=۰.۰۵۱), gambling severity (P=۰.۵۹), and age (P=۰.۲۹۳).Conclusion: Alexithymia had both a direct and indirect relationship with gambling severity through the mediating roles of emotion regulation and self-compassion. Moreover, alexithymia was significantly associated with risky decision-making and gambling frequency, through the mediating role of difficulties in emotion regulation, both directly and indirectly.
