Measures of the Behavioral Activation System (BAS) often conflate reward-reactivity (the core of the BAS) and impulsivity-related variance. The Appetitive Motivation Scale (AMS), a recently-developed BAS measure, has been proposed as a one-dimensional scale which deals exclusively with core reward-reactivity. However, we show here how a two-dimensional interpretation of the scale reveals components which are linked with both the core of the BAS and impulsivity. A clear pattern of associations and dissociations with other BAS- and impulsivity-related measures provides support for such a two-dimensional interpretation. The results are discussed, highlighting the parallels between the AMS structure and other BAS-related measures, and emphasizing the theoretical challenges which are inherent in developing reliable BAS-related personality measures.
► The Appetitive Motivation Scale was best described by a 2-factor solution.
► The two factors represent appetitive motivation and impulsivity, respectively.
► Convergent and discriminant validity evidence supports this interpretation.
