Interpersonal Pyschotherapy (IPT) is a style of therapy that was introduced in the 1970s by Gerald Klerman and Myrna Weissman. It is intended to serve a brief, attachment-focused psychotherapy that is intended to resolve interpersonal problems and to foster symptomatic recovery. It was developed primarily as a means of dealing with major depression based upon the premise that life events and relationships have a great impact on human moods. Likewise, moods impact life events and relationships. IPT has been empirically validated and expanded for use with other disorders and appears to be most effective when used in conjunction with medication.
