Abstract

In this paper, the factorial structure and the reliability of the Self-Monitoring Scale (18 items version) are tested on a sample of 291 Italians. Furthermore, an anxiety measuring scale (EPQ-R(N)) and an extroversion measuring scale (EPQ-R(E)) are used as external validation criterion. The results does not confirm Snyder's unidimensional model: in fact, the Principal Components Analysis on the Snyder's scale return 3 semi-orthogonal components: "ability to modify self presentation", "situational variability", and "social appropriateness". Moreover, the 3 components result associated in an unexpected manner to the external criterion. The Self-Monitoring Scale appears to describe not just one but a configuration of distinct theoretical constructs.
