Subjects were given artificial psychological test results that were discrepant in either positive or negative directions with their self-reports on the traits purportedly measured. Test results were given by a counselor identified as either a PhD or a counseling practicum student. Amount of discrepancy between test results and self-report significantly affected the amount of change in self-report of subjects in both positive and negative feedback conditions. Professional level of the interpreter affected change in self-report for all groups receiving positive or self-enhancing results and for subjects receiving negative results highly discrepant with their self-report.Research on variables affecting clients' acceptance of test results has focused primarily on the results of use of various techniques of interpreting test results (see Tyler, 1969). Investigations by social psychologists of the effects of communicator credibility and of feedback of information discrepant with existing self-concepts have become increasingly related to test interpretation (Bergin, 1962;Johnson, 1966).

However, neither study used professional counselors. Bergin contrasted a "research director" with a "high school student" ; Johnson had students rate the credibility of a senior psychology major as a test interpreter. The question of counselor credibility becomes important to the extent that
