Abstract
The factorial structure and invariance of the BIS/BAS scales of Carver and White were assessed across three samples from the USA, UK, and Italy. Previous validation studies of the BIS/BAS scales relied on individual samples drawn from English‐speaking populations only and failed to formally assess generalizability. The current study shows that the four‐factor structure proposed by Carver and White—i.e. one BIS and three BAS facets—achieved satisfactory psychometric properties in all three samples and that measurement invariance was obtained across countries. Latent mean differences due to gender and country were also investigated. Theoretical issues concerning the validity of the BIS/BAS scales are addressed. Copyright © 2001 John Wiley & Sons, Ltd.
