Confidentiality in psychotherapy has long been assumed. Recently, this confidentiality has been threatened by computer filing systems, the courts, and third party payers of client expenses. This study investigates client expectations of confidentiality and information subject to disclosure. Subjects (N=185) were undergraduate students who completed questionnaires describing 10 clinical problems and 8 potential disclosure situations. Subjects rated how much information they would expect to be divulged and how much information they would prefer to be released. The results indicated a three-way interaction between clinical problems, potential recipients of information, and expectations about release of client information. Subjects always preferred that less information be divulged than they expected to occur. Subjects expected information to be divulged. Since previous research has shown that clients do not disclose as much when they do not expect their communication to be confidential, psychotherapists should discuss the limits of confidentiality with their clients.
