Abstract
This study examined the impact of revised reinforcement sensitivity theory (r-RST) on two measures of problem gambling. Using 112 general population adult participants, two measures of r-RST, the reinforcement sensitivity theory of personality questionnaire (RST-PQ) and Jackson 5, were used to predict problem gambling operationalised using the South Oaks Gambling Screen and the Iowa Gambling Task (IGT). Hypotheses were that the behavioural approach system (BAS) would positively predict problem gambling and the behavioural inhibition system (BIS) would negatively predict problem gambling. Results found that the BIS negatively predicted problem gambling. The RST-PQ BAS reward reactivity subscale positively predicted problem gambling using the IGT. These findings add to the operational understanding of the r-RST personality model, its relationships to avoidance and approach behaviour in response to reward and punishment, and to understanding the aetiology of problem gambling.
