Abstract

Background: Asthma is a chronic condition that can affect people of all ages and be controlled with correct treatment. Universities settings for potentially accessing almost all students for asthma and allergy screening. Objectives: This study aimed to adapt the Asthma and Allergy Screening Questionnaire (AASQ) to the Turkish language and assess its psychometric properties for the purpose of evaluating asthma and allergy symptoms in university students and raising awareness among students about controlling the asthma. Methods: This study was conducted between February and April 2016 in 900 students who study in a faculty of university in Turkey and who agreed to participate. Linguistic validity was verified through front-to-back translation. Psychometric properties of the instrument were studied on a sample of 900 nursing students studying in a faculty of university in Turkey. The relationship between the students’ asthma risk factors and TR-AASQ (Turkish Asthma and Allergy Screening Questionnaire) scores was evaluated. Results: The content validity index of the translated instrument was “0.95”. Principal component analysis revealed three factors with an eigenvalue >1. Cronbach's alpha was found to be 0.787 for total scale and between 0.608 and 0.745 for the subscale. Test-retest total scale scores and item scores correlations were significant (p<0.01). We conducted CFA for models of three factor. The three factor model represented chisquare=1364.04 (df=62, p<0.001), χ 2 /df=22.00, RMSEA= 0.153, SRMR=0.081, GFI= 0.81, AGFI=0.72, CFI=0.81. Conclusion: The data obtained at the end of the study supported TR-AASQ as a valid and reliable tool for evaluating asthma and allergy symptoms in university students.
