The research used a cross-sectional design and subjects consisted of 447 female nurses working in ICU of 12 different hospitals graded from northern, central to southern area of Taiwan. The response rate was 82.36%. A self-administered questionnaire was used to collect data. The questionnaire had been passed to the ICU nurses who consented to fill in the questionnaire, which included the socio-demographic characteristics, health status, work status, the Effort-Reward Imbalanced (ERI) scale, and the quality of life scale (WHOQOL-BREF). The data was analyzed by using SAS 8.02 for Windows. The main findings of this study were as follows： 1. The mean score of overall quality of life of ICU nurses was 48.284±7.145 by testing with the Taiwanese WHOQOL-BREF. Within each domain, the highest score (12.642) was found in the social health quality of life, then was the physical domain, the psychological domain quality of life, the environment domain quality of life got the lowest score (11.490). 2. The association of self- perceived job strain by ERI model with the health-related quality of life by WHOQOL-BREF was statically significant. Two major variables, Effort-Reward status and over commitment, were found to explain 22.13% (Adj R Square) for the quality of life of nurses working in ICUs. 3. Regression mode, which WHOQOL is considered as the.independent variable has found several significant influence factors. These factors are low effort－low reward, high effort－low reward, overcommitted, education (postgraduate), salary(30000-50000 dollars), self-rated health status, happiness(extremely unhappiness), happiness(unhappiness), happiness (manageable), hospitals grade(local hospitals), serving for more then one department, employment(part-time), job title (professional nurse), and job title (nurse). The most two significant influence factors for health-related quality of life are self- rated health status and happiness. In addition, the capability of prediction for happiness factor (0.55) is higher than that of self-rated health status (0.289). The relationship between job strain and quality of life was evident in this research. The results of the study could have some contributions to managers of healthcare institutions, in the way of understanding more about the characteristics of job strain group in ICU nurses, the influencing factors of job strain and quality of life, and enhance the quality of life of ICU nurses.
