['The impact of grass pollen-induced allergic rhinitis (AR) on classroom/work productivity and activities can be assessed with a specific instrument: the Work Productivity and Activity Impairment Questionnaire plus Classroom Impairment Questions: Allergy Specific (WPAI-AS). This study evaluated the relationships between the WPAI-AS and other outcome measures in AR.', "Adolescents (aged 12-17) and adults (aged 18-65) consulting specialists for AR were enrolled in a four-week, multicentre, observational study. The management of AR was left to the physicians' discretion. Participants regularly rated the WPAI-AS, their symptoms (using the Rhinoconjunctivitis Total Symptom Score (RTSS) and a 0- to 100-mm visual analogue scale (VAS)) and quality of life (according to the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ)).", 'A total of 247 adolescents and 292 adults showed similar baseline impairments in classroom/work productivity and activities other than work. In both age groups, the WPAI-AS scores were moderately correlated with the RQLQ score and, to a lesser extent, with the VAS score and the RTSS. A multiple regression analysis indicated that the RQLQ score was a weak but statistically significant predictor of both impaired work/classroom productivity and daily activities. A 50-mm VAS cut-off categorized patients in whom AR had the greatest impact on productivity.'] Are in allergic rhinitis , work , classroom and activity impairments weakly related to other outcome measures?
