Psychometric Evaluation and Computerized Adaptive Testing Simulations of Myopic Refractive Intervention Quality of Life Item Banks.

ABSTRACT:

Purpose

To optimize the psychometric properties of myopia refractive intervention quality of life (QoL) item banks (IBs), and evaluate their performance using computerized adaptive testing (CAT) simulations.

Methods

In this clinical study, adults utilizing myopic refractive intervention modalities answered 204 items within seven IBs: Activity Limitation (AL); Comfort (CM); Concerns (CN); Convenience (CV); Emotional (EM); Mobility (MB); and Work (WK), referred to collectively as "MyoRICAT". The psychometric properties of each IB were assessed with Rasch analysis, and CAT simulations with 1000 respondents determined the average number of items needed to achieve moderate (standard error of measurement [SEM] = 0.387) and high (SEM = 0.30) precision levels.
