The purpose of this study was to develop a ratio scale to measure job satisfaction of nurses and health workers in health centers. Of the 224 health centers in Korea, 105 were drawn as the sample using disproportional stratified random sampling. The data collection period was from May 1 to June 30, 1990 and 771 nurses and health workers working at 75 health centers participated. Subjects were instructed to rate, according to the level of satisfaction, from one to four points, 42 items revised from the tool made by Stamps et. al. (1978). The internal consistency reliability of the tool was measured by Cronbach alpha and the corrected item-total correlation coefficient. As a result of the item analysis, one item was excluded since the item had negative correlation with total items. As a result of factor analysis on the 41 items with varimax or above. Labeling and numbering of 6 factors were as follows ; factor 1 (8 items) ; professional status of job factor 2 (6 items) ; Interaction factor 3 (8 items) ; Autonomy factor 4 (8 items) ; Administration factor 5 (7 items) ; Pay factor 6 (4 items) ; Job(Task) Further studies are needed to identify the relationship between this tool and the effectiveness of the health center and more research is needed for generalization.
