General Self-Efficacy Scale (GSES) which was developed by Sakano and Tohjoh in 1986 is an instrument to measure the individual's strength of general self-efficacy across a variety of everyday life settings. However, GSES had some psychometric problems because it was standardized only with the data from a population which consists of students. The first purpose of this study was to collect GSES data .from adult population to know the distribution of GSES scores in adults, and to verify the reliability of GSES by psychometric evaluation. The second purpose was to verify the clinical validity of GSES by making it clear how GSES scores are changing successively according to the fluctuation of depressive symptoms. Psychometric evaluation by test-retest method, odd-even method and so forth suggested that GSES has well enough high reliability, and these results were consistent with those of Sakano and Tohjoh (1986). The successive change of GSES scores of depressive patients revealed that while GSES scores of depressive patients were in a very low state, they increased significantly according to the elimination of depressive symptoms. It revealed also that the correlation coefficients between GSES scores and rating scores of depressive symptoms were negatively high. It was suggested that the GSES has high reliability for adult population and considerably high discriminant validity for depressive symptoms and is enough potential for the clinical and research application.
