The purpose of this study is analysis of the relationship between autonomy and group cohesiveness perceived by nurses and their job satisfaction, organizational commitment, motivation and intend to stay on jobs to develope the nursing staff management. The results are as follows: 1. Characteristics of subjects are not significantly different in perceived autonomy, but group cohesiveness, organizational commitment and intend to stay on jobs are different in nursing unit(p<.05). Educational background is significantly different in job satisfaction: nurses who has diploma show higher scores than who has baccalaureate degree(p<.05). 2. Perceived autonomy is related with job satisfaction, motivation and intend to stay on jobs but is not related with organizational commitment(p<.05). 3. Group cohesiveness perceived by nurses is significantly related with job satisfaction, organizational commitment motivation and intend to stay on jobs and their correlation coefficients are higher than that of perceived autonomy(p<.05). 4. The interaction effect of autonomy and group cohesiveness with all dependent variables is not significant(p>.05). The main effect on all dependent variables is presented as group cohesiveness. 5. The canonical correlation coefficient of independent variables and dependent variables is 0.503(p<0.000). The above results are important in the aspect of the development of strateges for retension of qualified nurses performing quality of nursing care and organizational efficacy. Autonomy and group cohesiveness perceived by nurses are important factors in nursing staff management; the further studys on job redesign and intervention strateges for enhancing group cohesiveness are needed.
