While much is known about the concept of likability, a single encompassing tool to measure likability has yet to be created. The Reysen Likability Scale measures the degree of likability for a target source. Using the current scale, a total of 150 participants rated 12 individuals who were videotaped while reading a paragraph. Tapes differed with respect to whether the people genuinely laughed, faked their laughter, or did not laugh while reading a paragraph. In the present study, the reliability, and convergent and divergent validity of the new scale were assessed. Coefficient alpha for the current scale ranged from .90 to .91. Laughter predicted higher likability ratings which demonstrated convergent validity. Divergent validity was illustrated using Goldberg's (1992) 100-Adjective Big Five Personality Test. Suggestions for research using the new scale are given.
