Difficult Colonoscopy and Personality Traits

For patients who need to undergo colonoscopy, we invite them to fill out a personality survey questionnaire after obtaining their informed consent. The questionnaire contains 60 survey questions, which cover the five dimensions of the Big Five personality traits. Each question has five options, corresponding to the five states of very disagree to very agree. The questionnaire was developed based on the Chinese population and has four norms applicable to different age groups to ensure the reliability of the questionnaire.
