BACKGROUND AND OBJECTIVE:
To establish and validate an assessment tool of cataract surgery performed by residents suitable for a competency-based curriculum.
PATIENTS AND METHODS:
A three-component evaluation tool was created based on review of the literature and was refined using a modified Delphi technique. Faculty surgeons viewed two videos of cataract surgery, performed by a novice and an expert, and completed the evaluation tool. Results were analyzed for the psychometric properties.
Evaluators concluded the scale had excellent face validity. Construct validity showed the scale to reliably distinguish (P < .001) between novice (30.3 ± 6.1) and experienced (48.3 ± 7.2) surgeons. Internal consistency of the scale was high, with Cronbach’s alpha equal to 0.981. Inter-rater reliability was high with an intraclass correlation coefficient equal to 0.811 (F(df) = 53.2 (25), P < .001).
The tool has excellent face validity, content validity, and reliability. Its task-specific, global-index scale and quantitative data form make it a valuable tool to assess residents’ surgical skills.
