Revised Reinforcement Sensitivity Theory and Laboratory Assessment of BIS and BAS in Children

There is considerable interest in Gray’s reinforcement sensitivity theory. However, few measures of the behavioral approach (BAS) and inhibition systems (BIS) exist for children. Moreover, the theory was substantially revised a decade ago and measurement instruments are still largely based on the old theory. Our aim was to revise questionnaire and laboratory assessments of BIS and BAS for children. Performance on the Point Scoring Reaction Time Task for Children-Revised (PSRTT-CR) conformed to theoretical expectations. Caregiver reports of BIS and BAS were associated with corresponding PSRTT-CR indices, suggesting cross-method convergent and discriminant validity. There was convergence with physiological correlates of BAS, but not physiological correlates of BIS. Overall, our revised measures represent promising instruments of children’s BIS and BAS.     

Comparison of the construct validity of the Gray–Wilson Personality Questionnaire and the BIS/BAS scales

345 subjects completed a translated, shortened version of the Gray–Wilson Personality Questionnaire (GWPQ), along with Russian versions of Carver and White’s BIS/BAS scales, the Eysenck Personality Profiler, the Eysenck Personality Questionnaire, and Spielberger’s State-Trait Anxiety Inventory. Exploratory factor analysis of GWPQ items pointed to a three-factor solution and three new scales were created which demonstrated adequate psychometric characteristics. Confirmatory factor analysis of the BIS/BAS scales showed that a four-factor model best fitted the data but the three BAS subscales should be treated as sub-factors of a second-order factor. Structural equation modelling showed that GWPQ scales generally explained Eysenck’s dimensions better than BIS/BAS scales. The distinction between GWPQ and Carver and White’s scales mainly concerned BAS measures. GWPQ BAS captured more of Psychoticism, whereas Carver and White’s BAS captured more of Extraversion.     

Carver and Whites’ BIS/FFFS/BAS scales and domains and facets of the Five Factor Model of personality

Few empirical studies have investigated the relationship between Gray’s Reinforcement Sensitivity Theory (RST) and the Five-Factor Model (FFM) of personality. In a large sample of undergraduates (N = 779), we examined the relationship between FFM domains and facets and the revised RST (see Gray & McNaughton, 2000). Regression and partial correlation analyses indicated that only FFM Agreeableness discriminates between the BIS and FFFS. Other differences at the facet level were found for Neuroticism facets of Self-Consciousness and Angry Hostility (negatively), Agreeableness facets of Compliance and Modesty, and Conscientiousness facets of Self-Discipline and Deliberation. These findings emphasize social inhibition and constraint in the BIS, compared to the FFFS.
