為了瞭解慢性精神疾患客觀生活品質的現況，研究者運用Heinrichs的21項生活品質量，在臺北地區選取一所醫學中心及一所地區醫院，針對精神科急性病房(33例)、日間病房(21例)、及門診病患(35例)，共收集有效樣本89例慢性精神病患為研究對象，進行生活品質的量化評估與統計分析。研究結果顯示慢性精神疾患的客觀生活品質的差異與疾病狀況(診斷及患病期間)、及在不同型態之醫療照護下皆有相關。研究結果包括：(1)精神分裂症個案的客觀生活品質明顯的低於情感性精神病者(p=0.0001)；(2)患病十年以上的個案其客觀生活品質明顯的低於患病期間在十年以內者(p<0.001)；(3)日間病房個案的整體客觀生活品質亦明顯的低於門診個案(p=0.0028)。這些結果也顯示Heinrichs的21項生活品質量表是一套有效的客觀生活品質測量工具，可以推廣運用於更大規模的慢性精神疾病客觀生活品質評估，且可被用來做縱向研究比較臨床醫療照護前後的療效，將更能深入瞭解精神病患的生活品質。

　　　　　The purpose of the study is to evaluate the changes of objective life quality (OLQ) of chronic mentally ill patients under the current psychiatric patient care system in the Taipei area. A total of eighty-nine valid cases were selected from medical centers and community hospitals with psychiatric acute wards (33 cases), day care centers (21 cases), and OPDs (35 cases). The 21-item OLQ scale introduced by Heinrichs was used to evaluate patients' symptoms, signs and objective functional status. The results of this study indicate that: (1) the OLQ of schizophrenic patients are lower than the affective disorder patients (p=0.0001); (2) The OLQ of chronic patients having more than ten years history are lower than those patients with less than ten years (p<0.001); (3) The cases treated at day care centers have lower OLQ than the OPD cases (p=0.0028). These results also indicate that Heinrichs' OLQ scale is a useful tool not only in the evaluation of the effectiveness of the current psychiatric care system but also for longitudinal study of proposed care programs for chronic mentally ill patients.
