目標：自評的健康相關生活品質可用於評量個人的身心健康狀態，而目前國內有關在學大學生的生活品質的探究有限，本研究目的在於探討這一群體的生活品質的預測因子及相關因素。 方法：採立意取樣，於臺灣北、中、南、東四區，選取15所大學院校參與，再以方便取樣方式施發1735份問卷，剔除無效問卷，共得1470份有效問卷。問卷內容包括：自尊、社會支持、生活品質及個人基本資料。使用的統計方法有描述性統計、多階層迴歸、變異數分析、Scheffe事後比較及t檢定。 結果：生活品質的顯著預測因子包括自尊、社會支持、性別。男生、自尊及社會支持高者，其自評生活品質為高。有關學校類別及學校地區的事後比較顯示，公立學校學生自評生活品質高於就讀私立學校及宗教設立學校的學生；就讀於中部地區的學生自評生活品質高於就讀北部及南部地區的學生。 結論：研究結果顯示，在探研大學生生活品質的議題上，除考量自尊、社會支持、性別外，環境因素，如學校類別或學校地區也應列入考量。

　　　　　Objectives: Self-reported health-related quality of life has been utilized as an indicator for individuals' health. Yet, research regarding college students' quality of life is scant in Taiwan. Therefore, the purpose of this study is to examine the quality of life among college students in Taiwan. Methods: 1735 students from 15 selected universities were invited to participate in the study. Among them, there were 1470 valid responses. A questionnaire was designed to test the following variables: self-esteem, social support, quality of life and demographic information. A hierarchical multiple regression model, ANOVA, Scheffe Post-hoc and t-test were chosen for data analyses. Results: the valid predictors for overall quality of life were self-esteem, social support, and gender. The results of the Post-hoc test indicated that public school students reported higher quality of life than students studying in private or religion-connected schools; moreover, students studying in central Taiwan reported higher quality of life, compared to their counterparts whose schools were in northern and southern areas. Conclusions: both individual factors, e.g. self-esteem, and environmental factors, e.g. school type, all have to be taken into account when dealing with the issue regarding quality of life.
