BITRAN, MARCELA et al. An instrument in Spanish to evaluate the performance of clinical teachers by students. Rev. méd. Chile [online]. 2010, vol.138, n.6, pp.685-693. ISSN 0034-9887.

Background: The modernization of clinical teaching has called for the creation of faculty development programs, and the design of suitable instruments to evaluate clinical teachers’ performance. Aim: To report the development and validation of an instrument in Spanish designed to measure the students’ perceptions of their clinical teachers’ performance and to provide them with feedback to improve their teaching practices. Material and Methods: In a process that included the active participation of authorities, professors in charge of courses and internships, clinical teachers, students and medical education experts, we developed a 30-item questionnaire called MEDUC30 to evaluate the performance of clinical teachers by their students. The internal validity was assessed by factor analysis of 5,214 evaluations of 265 teachers, gathered from 2004 to 2007. The reliability was measured with the Cronbach’s alpha coefficient and the generalizability coefficient (g). Results: MEDUC30 had good content and construct validity. Its internal structure was compatible with four factors: patient-centered teaching, teaching skills, assessment skills and learning climate, and it proved to be consistent with the structure anticipated by the theory. The scores were highly reliable (Cronbach’s alpha: 0.97); five evaluations per teacher were sufficient to reach a reliability coefficient (g) of 0.8. Conclusions: MEDUC30 is a valid, reliable and useful instrument to evaluate the performance of clinical teachers. To our knowledge, this is the first instrument in Spanish for which solid validity and reliability evidences have been reported. We hope that MEDUC30 will be used to improve medical education in Spanish-speaking medical schools, providing teachers a specific feedback upon which to improve their pedagogical practice, and authorities with valuable information for the assessment of their faculty.
