Objective biomarker of allergic rhinitis severity is necessary for monitoring disease severity and response to treatment in clinical setting and for research. We believe that psychological factors are the missing link between patient-perceived severity of allergic rhinitis and objective biomarkers. In our pilot study, several psychological factors were studied in relation to patient reported outcomes for severity of allergic rhinitis.
