Gender and trait rumination moderates the link between trait impulsivity and gambling problems severity in young adults

Trait impulsivity and trait rumination appear to uniquely contribute to problem gambling. However, only a limited number of studies have investigated their relationship with each other, and no study has tested whether their interplay could explain problem gambling. In this study, we aimed to examine these associations, especially focusing on the putative moderator role of gender. The present study utilized data from the first wave of the Budapest Longitudinal Study, representatively surveying young adults. The final, weighted sample consisted of N = 1202 (649 men; mean age = 28.04 years; SD = 4.31) participants who reported gambling in the past year. Gambling severity was assessed by the Problem Gambling Severity Index (PGSI), trait impulsivity was measured by Barratt Impulsiveness Scale short form (BIS-R-10), while rumination was assessed by the short version of Ruminative Response Scale (RRS). Multiple linear regression analysis showed significant positive association between impulsivity and problematic gambling, and we found that both trait rumination and gender moderated this association, even after controlling for depressed mood, age, level of education, and subjective relative wealth. For men, when the level of trait rumination was high, higher levels of trait impulsivity were associated with an increase in gambling problems. However, these associations were not found among women. Our results suggested that the interplay of trait rumination and trait impulsivity might contribute to problem gambling, potentially by the impulsive desire to alleviate negative mood states. Our results also revealed that these associations could be stronger among men than in women. •Trait impulsivity positively relates to problem gambling in young adults.•Higher trait rumination contributes to problem gambling in a representative sample.•Trait rumination and gender moderate the link of trait impulsivity and gambling.•Without rumination, impulsivity does not raise gambling risk among young men.
