This article introduces a new scale for the assessment of Appreciation for Creative Personality (ACP). The ACP scale is a brief 13-item forced-choice measure that assesses interindividual differences in the preference for interacting with creative people. ACP is considered an important factor of creative climate at the level of interpersonal interaction. Individuals who score high on ACP are thought to foster a creative climate in that they value creative traits in others. In two studies, the psychometric characteristics of the ACP scale were probed. The scale showed a clear unidimensional structure with evidence of good reliability and convergent, discriminant, and criterion validity. The ACP was substantially related to Big Five openness to experience, but predicted relevant criteria over and above openness, supporting the conceptual distinction between ACP and openness. In dyadic data analyses, participants' openness to experience was significantly associated with their parents' ACP, which shows that the ACP scale captured shared interpersonal variance. Moreover, parental ACP indirectly predicted participants' everyday creative activities via the path of openness. These findings suggest that the ACP scale is a useful tool for the study of social-environmental climate for creativity from an interpersonal perspective.
