Global Self-Esteem as a Correlate of Work-Related Attitudes: A Question of Dimensionality

We examined the dimensionality of one of the most frequently used measures of global self-esteem, the Rosenberg Self-Esteem Scale (RSE; Rosenberg, 1965). Although the RSE is assumed to be unidimensional, Kaplan and Pokorny (1969) provided evidence that the scale taps two independent constructs: self-derogation versus defensive assertion of self-worth, in our study a confirmatory factor analysis was conducted which supported the superiority of the Kaplan and Pokorny two-factor model over a one-factor model but indicated that their model provided a poor fit to the data. Consequently, an exploratory factor analysis was conducted which revealed two dimensions, one mostly defined by negatively worded items (self-derogation) and the second by positively worded items (self-enhancement). Although the correlations obtained were generally quite small, relations with work-related attitudes shown for the negative factor were in the opposite direction and somewhat larger than those shown for the positive factor.
