Propiedades Psicométricas de la Escala de Autoeficacia Percibida Específica para Situaciones Académicas (EAPESA) en Universitarios del Ecuador

Objective: To analyze the factorial structure, measurement equivalence, internal consistency, difficulty, and discrimination of the Academic Situations Specific Perceived Self-Efficacy Scale (EAPESA) in a sample of Ecuadorian university students. Methods: The study was based on an instrumental design using postulates from Classical Test Theory (CTT) and Item Response Theory (IRT). Participants: 570 students from Ecuadorian public universities, 76% women and 24% men, aged between 17 and 56 years (M= 25.29; SD= 6.5 years). Results: The factorial validity was confirmed through a unifactorial fit model, and the EAPESA was invariant in terms of gender. Additionally, the scale’s reliability is high at both global and group levels. Item discrimination and difficulty were found to be optimal. Conclusion: The EAPESA is a valid and reliable instrument for Ecuadorian university samples.
