在動力性人際關係團體取向為基礎之強制性團體治療中，以海洛因成癮者團體為例，由於成員在療程中皆需定期進行尿液嗎啡檢測，驗尿結果曲線圖可作為團體治療的素材。將尿液嗎啡檢測結果製作驗尿曲線圖作為心理投射和面質的工具，研究者試圖探討領導者的面質需如何以「團體視為一個整體」，而非只是面質個別成員。以及，面對成員接踵而來的憤怒與攻擊，領導者可以如何回應，發揮團體療效因子，協助個別成員與團體的成長。

In the study of compulsory group treatment based on dynamic interpersonal relationship approach, we used as an example, a group of heroin addicts under medical treatment. Because these patients were required to take the urine morphine test regularly during the course of treatment, the group would have viewed results of their urine tests as a reality confrontation. We formulated the urine morphine test into a urine test chart. This chart was used as both a psychological projection tool and confrontation tool, to explore how the group leader’s confrontation response had to change to be based on the “group as a whole” instead of based on individual group members. Furthermore, considering that the internal object was projected from individual group members, how would the leader have responded appropriately, bringing the group in line with therapeutic goal, and assisting the growth of both the group and its individual members.
