Design and validation of the Scale of Influence of Significant Others on the configuration of the self (ES-OTS).

Abstract

This research aimed to develop and validate an instrument that assesses the influence of Significant Others on the configuration of the self. The instrumental study was conducted with an incidental sample of 1,411 students from the State of Sonora between the ages of 17 and 43. First, the content validity was addressed by expert judges and then an exploratory factor analysis (factoring by principal axes) and confirmatory factor analysis (diagonally weighted least squares method with robust standard errors) were carried out to ensure the structural validity of the scale. The final version of the instrument consisted of 36 items grouped into eight factors. Its use is recommended to further studies on self-concept, paying attention to the Others that configure it.
