اعتماد به نفس دو بعدی : تئوری و اندازه گیری

In this paper, we offer a clarified account of global self-esteem as consisting of self-competence and self-liking and describe a revised instrument designed to measure the two correlated dimensions. In Study 1, four measurement models representing distinct conceptions of self-esteem are compared to confirm the a priori structure of the instrument. In Study 2, multiple reporters (self, mother, father) are used to provide evidence for convergent and discriminant validity in a multitrait–multimethod context. Advantages of the two-dimensional approach to measurement are discussed.

The past half-century has witnessed the ascension of self-esteem as a central construct in psychological theory. Its prominence, however, is coupled with considerable disagreement over how the construct is best conceived. This lack of consensus, and the impediment to progress it presents, has been lamented by reviewers of the literature over the years (e.g. Blascovich and Tomaka, 1991, Crandall, 1973, Shavelson et al., 1976, Wells and Marwell, 1976 and Wylie, 1974). Toward clarification, we adopt the position that global self-esteem consists of two distinct dimensions that have often been confused in the literature. In this paper, we present our conceptual and psychometric approach to this fundamental duality, with the aim of enhancing its utility for theory and research.
