Rasch development and validation of the "Medellin Dry Eye Inventory" (ME·Dry), an instrument to measure multidimensional quality of life compromise in patients with dry eye disease.

ABSTRACT:

Purpose

Dry eye disease (DED) is a common condition that affects the quality of life. There is a great need for better-developed scales that comply with Rasch model requirements.

Methods

Prospective study including patients with DED. A series of focus groups were performed to determine the best items to be included. A Rasch modeling methodology was used to validate the Medellín Dry Eye Inventory (ME·Dry). After iterative analysis and scale modification, a final version of the scale was attained which complied with the Rasch analysis expectations. Correlation between the different subscales of the ME·Dry and the Ocular Surface Disease Index (OSDI) was evaluated through Spearman correlation.

Results

A total of 166 patients with DED were included. Rasch modeling demonstr
