Rhinoconjunctivitis Quality of Life Questionnaire
Also known as: RQLQ, Rhinoconjunctivitis QoL
The RQLQ is a 28-item disease-specific quality-of-life instrument developed by Juniper and colleagues at McMaster University in 1996 to assess the impact of allergic rhinitis and allergic conjunctivitis on daily functioning. It captures symptom burden and activity limitation across seven domains: sleep, non-nose/eye symptoms, practical problems, nasal symptoms, eye symptoms, activity limitation, and emotional function. The RQLQ is the preferred outcome measure in allergic rhinitis clinical trials and is widely used in allergy and immunology practice to track treatment response.

When to use it
The RQLQ is indicated for patients with moderate-to-severe allergic rhinitis, particularly those with concurrent ocular symptoms (rhinoconjunctivitis). It is preferred in clinical trials evaluating antihistamines, intranasal corticosteroids, immunotherapy, or biologic agents. The RQLQ can monitor longitudinal disease trajectory in specialty allergy clinics and inform treatment escalation decisions. It is less useful in mild intermittent allergic rhinitis (minimal quality-of-life impact) or non-allergic rhinitis phenotypes.
Strengths & limitations
- Disease-specific: All 28 items directly address allergic rhinitis symptoms and activity impacts; no generic or irrelevant content
- Comprehensive domain coverage: Seven distinct domains (sleep, activity, emotion, ocular, nasal) capture the multidimensional impact of rhinoconjunctivitis
- Psychometrically sound: Cronbach's α>0.90 for overall score; test–retest reliability ICC>0.85; responsiveness to antihistamines, intranasal corticosteroids, and immunotherapy well-established
- Easy administration and scoring: 28 items require <10 minutes; mean calculation straightforward; no specialist interpretation needed
- Potential ceiling/floor effects in mild allergic rhinitis: Patients with minimal symptoms may score near-zero, limiting discrimination and sensitivity to further improvement
- Ocular emphasis: Patients with purely nasal disease (no eye symptoms) may find eye-specific items less relevant; a nasal-only version exists but is less commonly used
- Limited responsiveness to maintenance therapy: RQLQ may be less sensitive in stable, well-controlled seasonal allergies; better suited to moderate-severe or poorly controlled disease
Frequently asked
Can RQLQ be used for non-allergic rhinitis or vasomotor rhinitis?
RQLQ is validated for allergic rhinitis; responsiveness in non-allergic phenotypes is uncertain. While symptom overlap exists, non-allergic rhinitis patients may show different RQLQ response patterns. Consider disease phenotyping (allergy testing, nasal endoscopy) before assuming RQLQ is appropriate.
How sensitive is RQLQ to seasonal pollen variation?
RQLQ captures current disease state over the past 1–2 weeks. In highly seasonal allergic rhinitis, RQLQ scores fluctuate with pollen exposure. For longitudinal comparisons, measure at consistent times (e.g., peak pollen season for all patients) or use perennial disease populations.
A patient scores 2.5 on RQLQ overall; what does this mean clinically?
An overall score of 2.5 indicates moderate disease impact, suggesting that allergic rhinitis is noticeably affecting daily function (sleep, work, activity). This threshold typically warrants treatment intensification—e.g., step-up from antihistamine monotherapy to antihistamine + intranasal corticosteroid.
Is miniRQLQ (7 items) as reliable as full RQLQ (28 items)?
miniRQLQ is briefer but sacrifices some domain specificity. Full RQLQ is preferred in research and detailed clinical assessment. miniRQLQ may be suitable for rapid screening or resource-constrained settings, but clinically important nuances (e.g., separate eye vs. nasal symptom tracking) are lost.
