Positive association between trait impulsivity and high gambling-related cognitive biases among college students.

The present study examined whether people with high gambling-related cognitive bias are more likely to have higher levels of impulsivity than are those with low gambling-related cognitive bias. We used Barratt Impulsiveness Scale version 11, Zuckerman-Kuhlman Personality Questionnaire and the Iowa gambling task to explore differences in impulsivity between high and low gambling-related cognitive bias groups. Extreme group design was applied. 110 participants (high gambling related cognition group=58, low one=52) were recruited to complete the gambling related cognition scale, impulsivity self-rating scales and Iowa gambling task. Impulsivity self-rating scores were higher among subjects with high than among those with low gambling-related cognitive bias. Compared with individuals with low gambling-related cognitive bias, those with high levels of such bias showed greater degrees of trait impulsivity. We are unable to identify group differences on IGT. State and trait impulsivity may be dissociated.
