title: Validity and reliability of Turkish version of rhinitis and mini-rhinitis quality of life questionnaires.
abstract: BACKGROUND
  The aim of the present study was to develop the Turkish version of Rhinitis Quality of Life Questionnaire (RQLQ) and mini-RQLQ for clinical and research purposes.
  
  
  METHODS
  Study included 55 patients with Allergic Rhinitis (AR), aged 18-69. Demographic characteristics and symptom score (T4SS) were recorded. All patients filled in the Turkish RQLQ and mini-RQLQ. Reliability analysis included internal consistency and item-total score correlations. Construct validity analysis was performed by Known Group method by correlation of RQLQ and mini-RQLQ scores with T4SS and SF36.
  
  
  RESULTS
  Mean age of patients was 36.4+/-10.6. Mean T4SS was 4.7+/-4.1. Cronbach's alpha scores of all RQLQ domains were above 0.90 and those of mini-RQLQ were above 0.80. All items were significantly correlated with their domains. All correlation coefficients for item versus domain score were above 0.75 for RQLQ and above 0.84 for mini-RQLQ. Total RQLQ score was correlated with SF36 domains except physical functioning domain. Total mini-RQLQ score was significantly correlated with all SF36 domains (all r>-0.46). T4SS revealed significant correlation with RQLQ practical score (r=0.38). On the other hand, T4SS was correlated significantly with practical, nose and total scores of mini-RQLQ (r=0.33, 0.48, 0.34 respectively).
  
  
  CONCLUSIONS
  Health is the complete state of well-being and AR has major impact on quality of life (QoL), therefore it seems essential to include QoL measures in clinical evaluation along with traditional parameters. This study has demonstrated that RQLQ and mini-RQLQ are valid measures for use in Turkish patients with AR.
