Sports Medicine Patient-Reported Outcomes Fail to Meet National Institutes of Health- and American Medical...

To evaluate the readability of commonly used patient-reported outcome measures (PROMs) in the sports medicine literature to determine whether they meet the recommended reading levels set by the National Institutes of Health and the American Medical Association (AMA).

A readability analysis was conducted on 26 PROMs commonly used in the sports medicine literature. The primary readability metrics used were the Flesch Reading Ease Score (FRES) and the Simple Measure of Gobbledygook (SMOG) Index. Readability scores were obtained using an online readability calculator and compared against National Institutes of Health and American Medical Association guidelines. An FRES of 80 or greater or an SMOG Index less than 7 was applied as a threshold for a sixth-grade reading level or lower.

The average FRES and SMOG Index for all PROMs were 65 ± 13 and 9 ± 1, respectively, indicating an eighth- to ninth-grade reading level. Four PROMs met the FRES and SMOG Index threshold for readability: 12-Item Short Form Survey, Pediatric Quality of Life Inventory, Numeric Pain Rating Scale, and Musculoskeletal Function Assessment. The Patient-Specific Functional Scale, Disablement in the Physically Active scale, Upper Extremity Functional Index, Low Back Outcome Score, and International Knee Documentation Committee questionnaire were among the least readable PROMs.

Most sports medicine PROMs are written above the recommended sixth-grade reading level.

Ensuring that sports medicine PROMs meet recommended readability standards may improve data accuracy and patient comprehension. By reducing literacy barriers, clinicians can obtain more reliable responses, better evaluate outcomes, and ultimately enhance patient care.
