Brief summary: This study aims to investigate whether the personal characteristics of the endoscopist is associated with effect of interventions for colonoscopy quality improvement.

This is a prospective, 9-month, multicenter, single-blind study. Baseline quality indicators including adenoma detection rate, polyp detection rate, withdrawal time and adenomas per colonoscopy of each endoscopist were measured in the health promotion centers of academic hospitals for 3 months. Follow-up measurements of quality indicators were repeated every 3 months after each interventions (personal notification of quality indicators, open notification of quality indicators, and colonoscopy quality education by a GI faculty. At the end of the study, personal characteristics of each endoscopist was evaluated using fear of negative evaluation scale, cognitive flexibility inventory, and almost perfect scale.

Detailed description: Suboptimal colonoscopy quality is associated with development of interval colorectal cancer and colorectal cancer-related death. It is uncertain how to improve colonoscopy quality effectively. The quality of screening colonoscopy for colorectal cancer depends on the endoscopist who performed the examination. The aim of this study was to investigate the impact of endoscopists' personal characteristics on the quality of colonoscopy and effectiveness of intervention.

Eligibility criteria: Inclusion Criteria:

* Highly experienced board-certified gastroenterologists performed colonoscopies in health screening endoscopy centers.
* Endoscopists who sign the consent
* Patients for quality indicators of endoscopists

  * routinely perform outpatient screening, surveillance and diagnostic colonoscopy (first-time screening colonoscopies performed and had no previous colonoscopy within 3 years).

Exclusion Criteria:

* endoscopists who refuse to sign the consent
* Patients for quality indicators of endoscopists

  * Known hereditary polyposis syndrome, Inflammatory bowel disease, those with surgically altered anatomy, undergone previous colonoscopy within 3 years
