Abstract
Earlier work has indicated that certain groups of adults might be disproportionately inflexible in their communicative interactions, but conclusions are uncertain due to the accepted practice of sampling college students to develop and validate measures. This study compared working adults with college student respondents on the Communication Flexibility scale (Martin & Rubin, 1994). Results from two samples of working adults indicate that adults score lower on communication flexibility than do traditional college students. This reinforces researchers’ need to be aware that some measures’ norms may vary depending on the targeted population.
