Eighteen True/False items measure the extent to which a person observes and controls their expressive behavior to manage a desired social appearance. The scale is a psychometrically refined version of the original 25-item instrument, with improved internal consistency and factorial purity. High scorers are characterised by sensitivity to situational cues, social chameleon-like behavior, and the use of social comparison information to guide self-presentation.
