動力性人際關係團體心理治療，是以精神動力為導向，以人際關係為介入點的團體治療，本文報告一位患有重鬱症之已婚中年男性參與本團體之變化。個案在成長背景中，父親為相當權威的角色，因而造成個案平日在人際上，與父親及職場上司相處時感到畏懼，產生困難。在團體進行過程中，個案由於對治療者的移情關係，投射權威父親至治療者，故在團體早期呈現害怕逃避治療者之現象；經由再度的嘗試，個案發現治療者並未如想像中權威，進而轉變畏懼面對權威人物之內在客體；最終，將此經驗帶回生活中，重新嘗試與父親的主動，建立新的父子關係。

Dynamically interpersonal group psychotherapy is a therapeutic group with psychodynamic-orientated and interpersonal-approached entities. The change of object- and self-representation was reported on a married middle-age man with a diagnosis of major depression in the group. In the developmental history, the man had an authoritative father. Therefore, he had strong fear to get along well with his father and the boss and had transference toward the therapist which meant be projecting his father image into the therapist. Fear overwhelmed him to escape the group when he faced the therapist in the early stage. After some testing, he found the therapist was not so authoritative as his fantasy, which made him to transmute the internal bad object. Moreover, he brought this experience back to the ordinary life. After trying to reinteract with his father, he developed a new interactional pattern.
