Systematic review of subjective validation methods for computerized colonoscopy simulators

Area of Science:

• Medical Simulation
• Gastroenterology
• Educational Technology

Background:

• Subjective assessment of colonoscopy simulators is crucial for effective training.
• Existing validation methods for computerized simulators lack standardization.

Purpose of the Study:

• To review subjective validation approaches for computerized colonoscopy simulators.
• To inform the design of a standardized validation procedure for these simulators.

Main Methods:

• Systematic literature review of papers published after 2010.
• Searched PubMed, Google Scholar, ScienceDirect, and IEEE Xplore databases.
• Screened and reviewed papers on subjective validation of computerized colonoscopy simulators.

Main Results:

• Seven studies met the inclusion criteria.
• Questionnaires were universally used for subjective validation.
• Face validity was most frequently assessed, with content validity and usability less common.

Conclusions:

• A framework for assessing face validity in colonoscopy simulators was developed.
• The Colonoscopy Simulator Realism Questionnaire (CSRQ) is proposed as a model for future questionnaires.
• Ambiguous interpretations and mislabeling of validity types were noted issues in current research.
