Objective: To compile a questionnaire on optimism bias in career choice of undergraduate stu-dents and test its reliability and validity. Methods: Initial questionnaires were formed by consulting literature and questionnaire survey, and 524 valid questionnaires were collected from 543 subjects. The data were used for item analysis, reliability analysis and exploratory factor analysis of the questionnaires, and 249 valid questionnaires were collected from 270 subjects. The data were used for confirmatory factor analysis of the questionnaires. Results: The questionnaire contains 10 items, which are composed of positive and negative events. The two factors explain 49.928% of the total variance of the questionnaire. The confirmatory factor analysis shows that the questionnaire has good structural validity (X2/df = 1.436, CFI = 0.934, TFI = 0.913, RMSEA = 0.042, SRMR = 0.044). The Cronbach’s alpha coefficient of the total questionnaire is 0.721, and the Cronbach’s alpha coefficients of positive and negative events are 0.795 and 0.736, respectively. Conclusion: The reliability and validity of the questionnaire are good, and its quality level meets the requirements of psychometrics.
