Validation and reliability study of the Turkish version of the Pediatric Rhinitis Quality of Life Questionnaire.

The aim of this study was to develop a Turkish version of the Turkish Pediatric Rhinitis Quality of Life Questionnaire (PRQLQ) that is conceptually equivalent to the original and to evaluate its validity and reliability. The study included 102 children with allergic rhinitis (AR) aged 5 to 16 years. Demographic information, family history of allergy, and duration of AR were recorded. All patients completed the T4SS symptom score and PRQLQ. Reliability including internal consistency and item-total score correlations and validity analysis including Known Group method were performed. Activity limitations, emotional function and symptoms domains had successful Cronbach alpha scores of 0.62, 0.69 and 0.78, respectively. All items were significantly correlated with their own domain. Correlations of all the domain scores with the total score and the other domains were significant. Linear multiple regression reduced models revealed that both domain and total scores showed statistically significant sensitivity to T4SS. The Turkish PRQLQ is a valid and reliable measure for use in Turkish children with AR.
