Design and validation of a university teacher self-efficacy scale

Teaching self-efficacy stands out as an important mediator of academic practice and the teaching and learning process in the university environment. More and more educational approaches and models pick up their importance and consider their nature transversal to university functions. This article develops the design and validation of a reliable instrument capable of measuring the self-efficacy of university teachers. It is a study of an instrumental nature. The items are integrated into 4 dimensions and were validated in appearance and content by an expert judgment. To evaluate the reliability and validity of the tool, a sample of 153 university professors from various universities in Peru was used. Analyses of the individual quality of the items, of validity evidence based on the internal structure, and of reliability by internal consistency were carried out. A value of the coefficient V of Aiken greater than 0.8 was obtained in all dimensions of the instrument. The Cronbach's alpha coefficients of the 4 dimensions were equal to or greater than 0.70. Regarding the Omega coefficient, only the Educational Strategies dimension showed values higher than 0.70. Due to its low factor load, item 11 was removed from the final version of the instrument. The psychometric study showed that the University Teacher Self-efficacy Scale could be a reliable and valid instrument to measure the self-efficacy of university teachers.
