Development and Validation of the Self-concept Scale in Mexican Women

Abstract

Abstract. Objective. Show evidence of validity and reliability of a self-concept instrument. Method. 425 Mexican women between 18 and 62 years old participated. The exploratory and confirmatory factor analysis shows five factors (ethical-moral, social, physical self-concept, self-realization and dependence) grouping 20 items with reliability indices ω>.75 and adequate indicators of goodness of fit. Results. The multigroup comparison shows that the instrument is equivalent in its configuration and measurement weights between women up to 30 and over 30 years old. Correlations with anxiety and self-esteem instruments show evidence of validity through external criteria. The appearance of the dependency factor instead of the autonomy factor is discussed. It is concluded that the scale is brief, valid and reliable. Likewise, its usefulness in research and clinical practice is determined.
