Professional disclosure in counseling is the process of informing clients about the services being provided and the persons providing those services. It includes the issues of client expectation, accountability and consumerism and counselor credentialing. The effects of a professional disclosure statement on client expectations, behavior, and satisfaction were studied by assigning university counseling center clients to read a professional disclosure statement, general statement, or no statement before counseling. Clients who read the professional disclosure statement tended to: (1) be more likely to change their expectations of counseling; (2) have a better understanding of the counseling process; (3) have more realistic expectations; and (4) report greater satisfaction with the counseling outcome. The findings suggest that professional disclosure as an instrument of information and accountability appears to have face validity. (JAC)
