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

Abstract

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.
