This study aimed to adapt and validate the Congestion Quantifier Seven Item Test CQ7 for Spain. Methods CQ7 was adapted from English following international guidelines. The instrument was validated in an observational prospective study in allergic rhinitis patients with NC N 166 and a control group without NC N 35 . Participants completed the CQ7 MOS sleep questionnaire and a measure of psychological well-being PGWBI . Clinical data included NC severity rating acoustic rhinometry and total symptom score TSS . Internal consistency was assessed using Cronbach s alpha and test-retest reliability using the intraclass correlation coefficient ICC . Construct validity was tested by examining correlations with other outcome measures and ability to discriminate between groups classified by NC severity. Sensitivity and specificity were assessed using Area under the Receiver Operating Curve AUC and responsiveness over time using effect sizes ES . Results Cronbach s alpha for the CQ7 was and the ICC was indicating good reliability. CQ7 correlated most strongly with the TSS r p the PGWBI general health dimension r p and the MOS Sleep scale sleep short of breath dimension r p . Correlations with acoustic rhinometry were generally low. The instrument discriminated well between NC severity groups ES and AUC was indicating excellent sensitivity and specificity. The measure was responsive to change ES in patients reporting improvement in .
