Adaptación lingüística y psicométrica del Cuestionario de Estilos Atributivos Académicos (EAT-A).

Background: Students' attributions of their grades may affect their academic performance. However, lack of evidence supporting the validity and reliability of the instruments measuring attribution is a major concern. Objective: To analyze the factor structure, convergent validity and reliability of the Academic Attributional Style Questionnaire adapted to Mexican high school students (EAT-A). Method: The sample consisted of 557 Mexico City students of both sexes aged between 15 and 19. Using a confirmatory factor analysis for both success and failure attributions, a 7-factor structure and a 4-factor structure of the EAT-A were tested. The instrument's convergent validity, internal consistency and reliability were examined. Results: Only the 7-factor structure showed adequate fit indices: RMSEA = .046; SRMR = .053; CFI = .961; TLI = .952 and X²/gl = 2.72. In addition, the EAT-A evidenced convergent validity concerning success and reliability motivation. Conclusion: The EAT-A is a quick- and easy-to-administer instrument for measuring students' attributions of their grades in a reliable and valid manner. [ABSTRACT FROM AUTHOR]
