Problem Gambling and Sub-dimensions of Impulsivity among Regular Online Poker Players

Abstract

Introduction: Impulsivity is a personality dimension known to be closely linked to addictive behaviour, including problem gambling. The aim of the present study is to assess impulsivity and its sub-dimensions (non-planning, attentional and motor impulsivity) among a sample of regular poker players, in order to determine whether these subtypes are linked to problem gambling and its severity. Method: 232 regular online poker players completed online questionnaires (socio-demographic data, CPGI, BIS-11). CPGI was used to divide them into four groups according to the intensity of their gambling practice (non-problem gamblers, low problem gamblers, moderate problem gamblers and severe problem gamblers). Results: Impulsivity significantly differentiated gamblers according to the intensity of their gambling behaviour and correlated significantly with problem gambling, confirming the idea that impulsivity is linked to the severity of problem gambling. Among its sub dimensions, only attentional impulsivity did not discriminate between the four groups of gamblers. Motor impulsivity and non-planning were significantly higher in severe problem gamblers and correlated with problem gambling. Motor impulsivity was also a significant predictor of problem gambling. Discussion: Consistent with the literature, our results underline the link between impulsivity and problem gambling among poker players. In particular, motor impulsivity and non-planning appeared to play a role in the development and/or maintenance of problem gambling. These results may have clinical implications in terms of treatment and prevention, and open avenues of research regarding impulsivity among problem gamblers.
