Historically, ethical codes for therapists were drawn up to protect the professions from regulation by external agencies. Implicit in the ethical codes, however, is a model for the client-therapist relationship that fosters the goals of mental health. Just as ethical codes have been given specific content in standards for providers of psychological services in human service facilities, ethical codes can be given specific content in the client-therapist relationship. Therapists need to take responsibility for incorporating ethical standards into their practices so that clients' rights will be an integral part of therapy. We present four illustrative situations: providing clients with information to make informed decisions about therapy, using contracts in therapy, responding to clients' challenges to therapists ' competence, and handling clients' complaints.
