The purpose of this investigation was to provide normative and comparative data for the BigCAT, the adult form of the Communication Attitude Test, a sub-test of the Behavior Assessment Battery. The BigCAT, a 35-item self-report test of speech-associated attitude was administered to 96 adults who stutter (PWS) and 216 adults who do not (PWNS). The difference in the extent to which the two groups of participants reported a negative attitude toward their speech and speech ability, as measured by the BigCAT, was statistically significant. Moreover, the overlap in the scores of the PWS and PWNS was minimal, and the effect size attributable to group membership was very large. The BigCAT's high Cronbach Alpha coefficients, together with the fact that each of its items significantly differentiated PWS from PWNS, indicate that the BigCAT is an internally consistent measure of the attitude that they have about their speech. Gender did not have a significant influence on the attitude toward speech or speech ability of either the PWS or PWNS. Overall, the present data suggest that the BigCAT holds promise as an aid to clinical decision making that relates to the assessment and treatment of those who stutter.
