Mental Stress and Bowel Preparation Quality

The goal of this cross-sectional study was to explore the relationship between physical and psychological stress and the quality of bowel preparation before a colonoscopy examination, in order to improve the quality of bowel preparation. The main questions it aims to answer are: Does physical and psychological stress affect the quality of colonoscopic bowel preparation, and delay disease detection? How can we improve the quality of colonoscopy？ Participants will be asked to complete a questionnaire containing their demographics, history of diseases and drugs, lifestyle habits, and physical and 14-item perceived stress scale(PSS-14). Quality of bowel preparation was assessed by the Boston bowel preparation scale（BPS）.
