Abstract Objectives. Patient-reported outcome (PRO) measures are often used to diagnose laryngopharyngeal reflux (LPR) and monitor treatment outcomes in clinical and research set- tings. The present systematic review was designed to iden- tify currently available LPR-related PRO measures and to evaluate each measure’s instrument development, validation, and applicability. Data Sources. MEDLINE via PubMed interface, CINAHL, and Health and Psychosocial Instrument databases were searched with relevant vocabulary and key terms related to PRO measures and LPR. Review Methods. Three investigators independently per- formed abstract review and full text review, applying a previ- ously developed checklist to critically assess measurement properties of each study meeting inclusion criteria. Results. Of 4947 studies reviewed, 7 LPR-related PRO mea- sures (publication years, 1991-2010) met criteria for extrac- tion and analysis. Two focused on globus and throat symptoms. Remaining measures were designed to assess LPR symptoms and monitor treatment outcomes in patients. None met all checklist criteria. Only 2 of 7 used patient input to devise item content, and 2 of 7 assessed responsiveness to change. Thematic deficiencies in current LPR-related measures are inadequately demonstrated: con- tent validity, construct validity, plan for interpretation, and literacy level assessment. Conclusion. Laryngopharyngeal reflux is often diagnosed according to symptoms. Currently available LPR-related PRO measures used to symptomatically identify suspected LPR patients have disparate developmental rigor and important methodological deficiencies. Care should be exercised to understand the measurement characteristics and contextual
