目的：本文以療效因子的角度，探討歌唱團體治療對精神科康復之家的病人的影響，並 就性別、發病時間長短及發病前教育程度等面向來探討影響療效因子的可能因素。 方法：以新北市某精神科康復之十九位病人為研究對象，一組接受結構式的歌唱團體治 療，另一組僅接受較無結構性的卡拉ok團體活動，參與音樂歌唱之團體治療活動 共八週，八週後分別看兩組各個療效因子的差異。 結果：研究顯示實驗组所發揮出的療效因子分數最高的前兩名分別為：普同感、宣洩； 而對照組所發揮之療效因子最高分前兩名分別為：普同感、人際學習。另外，實 驗組十二個療效因子全高於對照組，且達統計顯著值；而療效因子分數高低與性 別、發病時間長短、教育程度於統計學上無顯著相關。 結論：歌唱團體治療對慢性思覺失調症患者具有助益，值得推廣並進一步以更大的樣本 研究其成效。

Objectives： The psychosis syndrome of schizophrenia is one of the most important mental disorders. Recreation therapy is one of the common treatment for schizophrenia, and singing group is one of the most common clinical recreation activity. Methods： In this research, we focus on the group singing therapy to identify the therapeutic factors on long-term psychiatric patients, with respect to patient gender, onset duration, and patient education. The subjects were 19 clients from a psychiatric rehabilitation home in New Taipei City. They joined singing group in 8 weeks. We used Yalom's Therapeutic Factors Questionnaire to measure the factors and t-test to compute the factors of influence. Results: The top two therapeutic factors of experimental group were universality and catharsis; the top two therapeutic factors of control group were universality and interpersonal learning. Besides » the 12 therapeutic factors of the experimental group whole higher than the control group, and 12 of them reached significant level(p < 0.05). And, the therapeutic factors of the experimental group is irrelevant to the patient gender, patient education and the length of time of onset. Conclusions： It is suggested that group singing therapy may benefit to long-term psychiatric patients, and future research could enlarge samples to explore the therapeutic factors of group musical therapy.
