This study analyzes the relationships among quality of life, workaholism and psychological capital. The sample of the study consists of 212 registered employees of Shahid Dr. Beheshtei Hospital in Shiraz. Subjects have been selected using convenience sampling. World Health Organization Quality of life Questionnaire, Luthans psychological capital questionnaire and workaholism analysis questionnaire (Samani and Ahmadi) have been used in the present study. The research shows that there is a significant relationship between psychological capital and quality of life components while workaholism is not related to quality of life components. It is concluded that workaholism cannot predict quality of life components whereas psychological capital components predict quality of life components significantly.
