Adaptation to Spanish and Validation of the Rhinitis Control Assessment Test questionnaire.

Abstract

The Rhinitis Control Assessment Test (RCAT) is a patient-based questionnaire that is widely used to evaluate control of rhinitis. Objective: To develop and validate a Spanish version of the RCAT (RCATe). After translation and cultural adaptation of the original RCAT, this multicenter, observational, prospective study evaluated the properties/attributes of the RCATe by assessing its validity, reliability, responsiveness, effect size, minimal important difference and cut point. The recruited sample comprised 252 allergic rhinitis (AR) patients from 27 allergy and otolaryngology departments in hospitals throughout Spain. Significant and strong correlations were found between the RCATe and the total nasal symptom score and the visual analog scale (-0.79 and -0.77, respectively; P20 (area under the receiver operating characteristic curve, 0.746; sensitivity, 58.3%; specificity, 90.9%). The psychometric evaluation and validation of the RCATe indicated good reliability, validity, and responsiveness, thus suggesting that it is effective for measuring control of AR symptoms by Spanish-speaking patients.
