Abstract: | The Behavioral Inhibition System and Behavioral Activation System Scales (BIS/BAS scales) are the most widely used measures
designed to assess Gray’s Reinforcement Sensitivity Theory. However, questions remain regarding its factor, convergent, and
discriminant validity. We assessed these properties in two samples of undergraduates (N = 723, N = 103). In Study 1, confirmatory factor analysis supported previous findings that suggested removal of several items, resulting
in acceptable fit for a four-factor model. Convergent and discriminant validity were assessed for the original and revised
scales. In Study 2, a public speaking task was used to assess validity of the scales in reference to positive/negative affect.
Convergent and discriminant validity for the revised scales were not substantially different from the original scales. We
suggest that future researchers should consider the use of the revised measure we describe. We also suggest that the creation
of a revised BIS/BAS scale using new items may be warranted. |
