There is a great need for better-developed scales that comply with Rasch model requirements.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>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 Medell\u00edn Dry Eye Inventory (ME\u00b7Dry). 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\u00b7Dry and the Ocular Surface Disease Index (OSDI) was evaluated through Spearman correlation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 166 patients with DED were included. Rasch modeling demonstrated an excellent behavior for the ME\u00b7Dry, including four subscales:\n                      <jats:italic toggle=\"yes\">Symptoms<\/jats:italic>\n                      ,\n                      <jats:italic toggle=\"yes\">Triggers<\/jats:italic>\n                      ,\n                      <jats:italic toggle=\"yes\">Activity Limitation<\/jats:italic>\n                      , and\n                      <jats:italic toggle=\"yes\">Emotional Compromise<\/jats:italic>\n                      . Infit and Outfit parameters were all between 0.50 and 1.50, with excellent category utilization. Person and item separation and reliability were excellent for all subscales.
