Objective: To investigate the correlation between subjective and objective assessments of nasal obstruction and psychological status in patients with allergic rhinitis, and to analyze the characteristics of patients with subjective-objective discordance. Methods: This retrospective study included 100 patients with allergic rhinitis from Beijing Haidian Hospital between January 2025 and October 2025. Subjective symptoms were assessed using the visual analogue scale (VAS), rhinoconjunctivitis quality of life questionnaire (RQLQ), total nasal symptom score (TNSS), and total non-nasal symptom score (TNNSS). Psychological status was evaluated using the self-rating depression scale (SDS) and self-rating anxiety scale (SAS). Objective nasal ventilation function was assessed through nasal effective resistance, nasal cavity volume, and minimal cross-sectional area. Spearman correlation analysis was employed to explore the relationships among these indicators. Results: The VAS score was 6.18±2.35, RQLQ total score was 86.20±36.46, SDS standard score was 50.28±11.74, and SAS standard score was 45.99±11.42. The nasal effective resistance was 1.00±0.38 Pa/(cm3·s), nasal cavity volume 0-7 cm was 8.75±3.52 cm3, nasal cavity volume 2-6 cm was 4.93±2.29 cm3, and minimal cross-sectional area was 0.43±0.27 cm2. Spearman correlation analysis revealed a strong positive correlation between SDS and SAS standard scores (r=0.807, P<0.01). RQLQ total score showed significant positive correlations with TNSS score (r=0.646, P<0.01), VAS score (r=0.585, P<0.01), SAS standard score (r=0.578, P<0.01), and SDS standard score (r=0.538, P<0.01). In patients with subjective-objective discordance, RQLQ total score was positively correlated with SDS standard score (r=0.476, P<0.05) and SAS standard score (r=0.524, P<0.01), while nasal cavity volume showed significant negative correlations with psychological status scores (r=-0.650 to -0.662, P<0.01). Conclusion: Quality of life is closely associated with psychological status in patients with allergic rhinitis. Patients with subjective-objective discordance exhibit a distinctive correlation pattern, with objective nasal cavity volume showing significant negative correlations with psychological status, suggesting that psychological factors play an important role in nasal obstruction perception.
