Abstract

The purpose of this research was to develop a stress inventory applying to nuclear power plant operators and explore various methods of improving job performance of the operators. The inventory constructed by this study consists of three parts. First, 'job stress' which measures various stress sources such as individual, group, environment and task-specific factors. Second, 'resulting behaviors' which measures various damages of physiological, psychological and behavioral aspects as well as the strength of social support system. Finally, 'personality' which measures factors such as aggression, sensitivity and timidity. Reliabilities of the test varied with the sub-scales: .71∼.89 in job stress, .81∼.96 in resulting behaviors, and .60∼.91 in personality sub-scales. Factor analysis was conducted to find 3 factors. The first factor contains personality, the second resulting behaviors, and the third job stress. Relatively high correlations are calculated among the objective stress scores earned from the test and the subjective stress appraisal reported by the individuals and their job change wishes. Therefore it can be said that the test constructed in this study is validated. (Korean J Str Res 2008;16:1∼11)
