Further validation of the Penny Beliefs Scale - Weapons

The Penny Beliefs Scale - Weapons (PBS-W) comprises of 36 items that measure young people’s beliefs about carrying and using weapons. It was designed to facilitate our understanding of weapons carrying and use. The PBS-W has excellent internal reliability (Cronbach’s alpha of .92), extremely good test-retest consistency (ICC = .83) and is significantly positively correlated with self-reported delinquency. In order to further demonstrate the utility of the PBS-W it was compared with other measures that would be expected to be associated with weapons carrying and use. The PBS-W, the Eysenck Personality Questionnaire (EPQ-R-SV), the Maudsley Violence Questionnaire (MVQ), the Barratt Impulsiveness Scale (BIS-11), and the Brief Measure of Sensation Seeking (SS2) were administered to 189 school pupils in South Wales, aged between 16 and 18 years. Results demonstrated that the PBS-W is significantly positively correlated with EPQ Psychoticism (P), violent cognitions, impulsivity, and sensation seeking. Multiple regressions, controlling for gender and impression management (EPQ-Lie), showed that violent cognitions predicted beliefs about carrying and using weapons above and beyond P, sensation seeking and impulsivity. These findings suggest that violent cognitions are the single most powerful predictors of positive beliefs about carrying and using weapons.
