A classic personality measure of metacognition was developed by John Cacioppo and Richard Petty (1982) entitled, The Need for Cognition Scale (NCS). This is a widely used 18-item Likert scale that assesses “the tendency for an individual to engage in and enjoy thinking” (Cacioppo & Petty, 1982, p. 116). The NCS has been cited in over 3000 articles and has well established psychometric properties. For more information please read the original article by Cacioppo and Petty (1982).
