The present instrumental study aimed to describe the psychometric properties of the Coping with Pre-Exam Anxiety and Uncertainty Scale (COPEAU-A) in Chilean university students. 230 first-year students from a university in the north of Chile participated, where 67,4% were women and 32.6% men, with an average age of 18,9 years. By confirmatory factor analysis, using a robust weighted least squares method (WLSMV), five models were compared, finding the best fit indicators in the composite of four oblique factors with 20 ítems (X2=228,795, gl=164, p<,01; X2/gl=1,395; TLI=,929; CFI=,939; RMSEA=,042). The reliability of the four factors was adequate, showing McDonald's Omega coefficients between ω=,716 and ω=,873. In turn, the results showed the factorial invariance of the instrument according to sex. It is concluded that the psychometric properties of COPEAU-A would support its use to ...

Introduction: The UWES is one of the most widely used instruments in the world to measure academic engagement. Objective: The objective of this study was to describe and compare the psychometric properties of the UWES 17S and the UWES 9S in Chilean university students. Method: 541 students from a Chilean university participated, who voluntarily entered the indicated instruments. 61.6% of them were in the first year and 38.4% were at higher levels. Results: When comparing seven structural models, the best fit indicators were found in the UWES 9S according to a three-factor model and a bifactor model (X2/df=2.316; CFI=.977; TLI=.952; RMSEA=.071). The UWES 9S showed McDonald’s ω reliability indicators between .67 and .83 in its three factors, also demonstrating the invariance of its three-factor structure according to sex and at different levels of study. Discussion: It is concluded that...

Background: Perceived stress refers to the degree to which people perceive the demands of their environment as unpredictable and uncontrollable. The PSS-14 and PSS- 10 scales are the most widely used instruments worldwide to assess this construct. Objective: To describe the psychometric properties of the EEP 14 and 10 items in Chilean teachers, and to investigate the structural invariance of its models according to teachers’ gender Method: An instrumental study was carried out in a sample of 206 teachers. Results: Confirmatory factor analysis, using a robust maximum likelihood (MLR) method, showed the best fit indicators in the models of two related factors: in the PSS-14 (X2 = 166.693, df = 76, p < .001; CFI = .918; TLI = .901; RMSEA = .076) and in the PSS-10 (X2 = 59.979, df = 34, p < .001; CFI = .968; TLI = .957; RMSEA = .061). The McDonald’s ω coefficients were favorable f...
