Primary Outcome Measures

Name	Time	Method
Boston Bowel Preparation Scale (continuous)	Perioperative/Periprocedural	Quality of bowel preparation measured by the Boston Bowel Preparation Scale. Scores range from 0 through 3. Higher scores indicate a better outcome..

Secondary Outcome Measures

Name	Time	Method
Boston Bowel Preparation Scale (categorical)	Perioperative/Periprocedural	Boston Bowel Preparation Scale adequacy of preparation score ≥ 2 in all regions.; Quality measured by the Boston Bowel Preparation Scale. Scores range from 0 through 3. Higher scores indicate a better outcome..
Polyp detection rate proportion	Perioperative/Periprocedural	Proportion of individuals undergoing a colonoscopy in whom at least one polyp is detected. Values range from 0 through 1. Higher values indicate a better outcome.
Adenoma detection rate proportion	Perioperative/Periprocedural	Proportion of individuals undergoing a colonoscopy in whom at least one adenomatous polyp is found. Values range from 0 through 1. Higher values indicate a better outcome.
Adherence to bowel preparation instructions	Perioperative/Periprocedural	Following what was told to do by bowel preparation instructions. Total of 7 original questions scored as no for 0 or yes for 1 with a total score ranging from 0 through 7. Higher values indicate a better outcome.
Amsterdam Preoperative Anxiety and Information Scale	baseline	Self-assessed at baseline using the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Scores range from 6 through 30. Higher scores greater anxiety.
Overall experience with the bowel preparation process	Perioperative/Periprocedural	Self-report about experience with the bowel preparation process. One original question with 5 choices of very unpleasant, unpleasant , neutral , pleasant , very pleasant . There is no score. The best answer would be "very pleasant."
Desire to undergo future colonoscopies if indicated	Perioperative/Periprocedural	Self-report about having another colonoscopy. One original question with 5 choices of strongly disagree, disagree, neutral, agree , strongly agree. The best answer would be "strongly agree."
Cecal intubation rate proportion	Perioperative/Periprocedural	Proportion of colonoscopies in which the endoscope successfully reaches the caecum. Values range from 0 through 1. Higher values indicate a better outcome.
Withdrawal time	Perioperative/Periprocedural	Duration in minutes taken to withdraw the colonoscope from the caecum to the rectum. Values range from 1 through 60. Higher values indicate a worse outcome.
