Objective  To evaluate the reliability of the Advanced Dundee Endoscopic Psychomotor Tester (ADEPT).

Design  The Advanced Dundee Endoscopic Psychomotor Tester was developed for objective evaluation of bimanual endoscopic tasks. The system is in several aspects relevant to an actual endoscopic environment, and initial studies showed a strong correlation with clinical competence. Twenty medical students were tested on ADEPT (10 runs in 2 sessions). Their performances for 2 sessions were analyzed by the Spearman correlation to examine test-retest reliability. Coefficient was used to indicate the internal consistency of the system.

Results  There was no significant improvement in task performance during the 10 runs. A positive correlation on ADEPT performance was found between the 2 test sessions. A coefficient of .98 was observed between the different tasks of ADEPT.

Conclusion  These findings confirm that ADEPT is a reliable system for assessment of bimanual endoscopic task performance.
