Compilation of questionnaire for quality evaluation on problem-based learning of Neurology and analysis of its reliability and validity / 中华医学教育探索杂志

ABSTRACT

Objective:To design and compile quality evaluation questionnaire on problem-based learning (PBL) of Neurology and to test its reliability and validity.Methods:Referring to the framework of the evaluation system and according to the characteristics of the discipline, we designed the questionnaire on PBL of Neurology. The clinical medical students who participated in neurologic PBL course were taken as the objects of investigation. The reliability of the questionnaire and the reliability of internal consistency were tested. Correlation analysis and exploratory factor analysis were used to evaluate the validity of the questionnaire.Results:The questionnaire on PBL of Neurology included three first-level indicators teaching plan quality evaluation, teaching method evaluation and teaching quality evaluation, containing 6 second-level indicators and 25 third-level indicators. The correlation coefficient ρ=0.990 ( P<0.01) showed that the retest reliability was good. The cronbach's α coefficient is 0.901, meeting the internal consistency reliability requirement. And the content validity correlation coefficient was 0.307-0.7 ( P<0.05), indicating that each third-level index had a significant correlation with the total score, and the questionnaire item design was good. The three first-level indicators were used as common factors to evaluate the structural validity by exploratory factor analysis and identify the direction of optimization. Conclusion:The questionnaire has good reliability and validity, which can be used as a tool for scientific evaluation on PBL of neurology, and also provide an optimization direction for further research in the future.
