Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ)

Name of questionnaire Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ)
Type of questionnaire-description Developed to assess the quality-of-life impact sustained by adults with allergic rhinoconjunctivitis experienced at night.
Number of items 16 with one week recall 
Number of domains & categories 4 domains
Name of categories/domains   problems with sleep (4 items), symptoms during sleep time (5 items), symptoms on waking in the morning (4 items) and practical problems (3 items).
Scaling of items 7-point scale (0 = not troubled - 6 = extremely troubled). 
Scoring available: with permission or free All items are weighted equally. Mean score is calculated across all items within each domain. Overall score is the mean across all items. Higher scores reflect lower quality of life. 
Test-retest reproducibility Reported, for overall score intra-class correlation coefficient =0.87, slightly lower values for the domains (0.74 to 0.83). Among the 73% of patients who showed clinically important improvement or deterioration in health status, within-group changes were shown in overall and domain score (p<0.001). The NRQLQ detected between-group differences (stable vs. change) (p<0.001). Responsiveness index for overall score was 0.93 (Juniper EF, Rohrbaugh T, Meltzer EO.  A questionnaire to measure health-related quality of life in adults with nocturnal allergic rhinoconjunctivitis.  J Allergy Clin Immunol 2003, 111: 484-90).
Internal consistency Not reported
Validity Cross-sectional correlations between the NRQLQ and other measures of health status were close to a priori predictions providing evidence of construct validity (Juniper EF, Rohrbaugh T, Meltzer EO.  A questionnaire to measure health-related quality of life in adults with nocturnal allergic rhinoconjunctivitis.  J Allergy Clin Immunol 2003; 111: 484-90). 
Minimally important difference No minimally important difference has yet been established for the NRQLQ. A change of 0.5 on HRQL instruments that use a 7-point scale (eg, the RQLQ, AQLQ) has been postulated to be the minimally important difference necessary to attain clinical relevance; a difference of 1.0 indicates a moderate change, and a difference greater than 1.5 demonstrates a large change (Mintz M, Garcia J, Diener P, Liao Y, Dupclay L, Georges G. Triamcinolone acetonide aqueous nasal spray improves nocturnal rhinitis-related quality of life in patients treated in a primary care setting: the Quality of Sleep in Allergic Rhinitis study. Ann Allergy Asthma Immunol. 2004, 92(2):255-61).
