Multiple Conjoint Psychotherapy can be best described as a treatment strategy rather than as a separate system of psychotherapy. It is used to alter a disturbed relationship between family members (husband and wife, or siblings) by focusing on the interaction between the participants. Typically, two therapists (multiple or co-therapists) meet with the family members in group sessions (conjointly). This therapy therefore involves four or more people (two therapists and two clients) and can be either the exclusive means of treatment or it can be used as an adjunct to the individual therapy of separate family members (with occasional multiple conjoint sessions). Usually the two therapists will be of both sexes, and the most common group of people treated by this method are married couples. (8 pp.)
