Adaptación y Validación en Español de la Escala de Credibilidad en Profesores Universitarios

Abstract

The purpose of the study was to adapt to and validate to Spanish the Source Credibility Measure (McCroskey & Teven, 1999) to assess the credibility of university professors. The participants were 352 students from the University of Seville from different courses in the field of Social Sciences. The exploratory factor analysis generated an alternative three-factor model to the original one. However, both the alternative model and the original model presented adequate internal consistency not only in the global scale but also in the three subscales, good indexes of goodness of fit as demonstrated by the confirmatory factor analysis, supporting the factorial structure of three factors; invariance across sex and evidence of concurrent validity with academic motivation. It is concluded that the original model as well as the alternative model of the Source Credibility Measure are valid and reliable instruments to assess the credibility of university professors.
