The Rosenberg Self - Esteem Scale, a widely used self - report instrument for evaluating individual self - esteem, was investigated using item response theory. Factor analysis identified a single common factor, contrary to some previous studies that extracted separate Self - Confidence and Self - Depreciation factors. A unidimensional model for graded item responses was fit to the data. A model that constrained the 10 items to equal discrimination was contrasted with a model allowing the discriminations to be estimated freely. The test of significance indicated that the unconstrained model better fit the data - that is, the 10 items of the Rosenberg Self - Esteem Scale are not equally discriminating and are differentially related to self - esteem. The pattern of functioning of the items was examined with respect to their content, and observations are offered with implications for validating and developing future personality instruments.
