Abstract

Introduction: For the development of medical education within the framework of the concept of accountability, the preferred measurement tools for program evaluation should be reliable Reliability refers to the consistency of scores obtained with a certain measurement tool.
Objective: In this study, we aimed to evaluate the internal consistency reliability analysis of the qualitative research course feedback with classical test theory (Crohnbach alpha) and generalizability theory (G coefficient).
Method: In this study, feedback data of 46 participants from qualitative research courses implemented by the researcher were evaluated. The descriptive analyzes of the data of the feedback scale and reliability coefficients were determined according to the classical test theory and generalizability theory.
Results: In the evaluation of feedback by classical test theory, Crohnbach's alpha coefficient was calculated as 0.947 in the evaluation of the 20-item instrument of 47 participants. In the evaluation of the scale with generalizability theory,were estimated for predicting the single-surface crossed patterned variance components. G coefficient was calculated as 0,95.
Discussion: Reliability analysis of measurement tools preferred as data collection tools for program evaluation is important for accountability. In the literature, 0.70 and above is accepted as the universal reliability standard in reliability analyzes. In the reliability analysis of the scale in our study, it was considered acceptable according to the classical test theory and generalizability theory. We believe that the feedback scale evaluated in the scope of our study can be used as a reliable measurement tool in the evaluation of this training program.
