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). |
