Abstract

Background and Objectives: Self-confidence is an individual characteristic in Students that enables them to have a positive or realistic view of themselves. The purpose of present study was to evaluate the validity and psychometric properties of the Self-confidence Questionnaire (PEI) Methods: This cross-sectional study was conducted on 100 Students of four medical universities. Validation of this Questionnaire included the steps of translation, content validity, face validity, repeatability and internal consistency. Results: The mean age of the participants in this study was 32. 1 (SD = 5. 5) years. The majority of the Students were postgraduate Students (47%) and the least (11%) were undergraduate Students. The results of this study showed that the overall relevancy and clarity of the questions were 92% and 83%, respectively. The percentage of agreement on overall comprehensiveness was 100%. Cronbach's alpha coefficient and interclass correlation coefficient were higher than 0. 7 in all domains. The ICC of each question was also between 0. 72 and 0. 98. Conclusion: Based on the results of this study, the Persian version of the PEI Questionnaire has an appropriate reliability for use in the Student population of Iranian universities.
