Diseño y validación de una escala de autoeficacia en la asesoría de tesis

Given the lack of instruments to measure the sense of efficacy in thesis advising, the objective was to design and validate a scale to assess self-efficacy in thesis advising (EA-AT), under an instrumental study, with 601 undergraduate advisors between 25 and 65 years of age, assigned to education, medicine, nursing, nutrition, psychology, administration and accounting, selected under a non-probabilistic purposive sampling in seven universities in three regions of Peru. The scale design was based on 15 indicators found in the scientific literature. Content validity was analyzed with Aiken's V coefficient, internal structure with exploratory factor analysis (EFA) and reliability with Cronbach's Alpha coefficient. The results indicate that all items reached a favorable evaluation (V > .70), when applying the EFA only nine items saturated in a single factor that explains 60.38% of the total variance of the scale and their factor loadings range between .61 and .86. Robust analyses (X2 = 94.737; p = .000; CFI = .986; GFI = .983; AGFI = .97; RMSEA = .07) show that the unidimensional structure is satisfactory and the reliability acceptable (α = .943; 95% CI = .92-.95). It is concluded that the EA-AT is a brief measure and presents initial psychometric evidence of validity and reliability in Peruvian thesis advisors.
