Structure of the Personal Self-Concept (PSC) Questionnaire1

The aim of this instrumental study is to determine whether the empirical data confirm the structure of the Personal Self-Concept (PSC) Questionnaire, made up of four scales: Self-fulfillment, Autonomy, Honesty and Emotional self-concept. The inclusion of these scales is justified according to the conceptual review of the personal development, as well as the review of the instruments, which partially measures this domain of the self-concept. A total of 1,135 people completed the questionnaire; 559 randomly selected responses of people between 15 and 65 years old were used for a confirmatory factorial analysis. Of the three models assessed (unidimensional, four interrelated factors and four factors and one second-order factor), the four-dimensional one has the best goodness of fit, though the second-order factor model hasn’t that bad fit index. Finally, the practical implications of the identification of specific dimensions of self-concept are discussed, and new research questions are posed in light of the results obtained.
