On the factorial structure of self-esteem as measured by the Italian translation of the Self-Liking/Self-Competence Scale-Revised (SLCS-R)

In two studies, we investigated the structure of the Self-Liking/Self-Competence Scale – Revised (i.e., SLCS-R; Tafarodi & Swann, 2001), which was developed to measure two distinct dimensions of self-esteem: Self-competence and self-liking. In Study 1 we provided evidence that the two sub-scales actually address different aspects of self-esteem. In Study 2 with Confirmatory Factor Analysis we showed that a Multi-trait–Multi-method model including the dimensions of self-esteem as different traits, and positive versus negative wording of items as different methods, provided a superior fit to the data as compared to both a unidimensional model of self-esteem and to a bidimensional model not including the wording factor.
