Allergic asthmatic subjects showing seasonal rhinitis symptoms will be recruited. The discriminative (internal consistency, cross sectional construct validity and reliability) and evaluative (responsiveness and longitudinal construct validity) properties of the RCSS will be evaluated as well as the relationship between rhinitis control and asthma control. RCSS will be completed at various time points during the seasonal allergic period.
