Development and validation of the Pediatric Asthma kNowleDge and mAnagement (P.A.N.D.A) questionnaires

Abstract

Objective The objective of this study was to assess the validity, feasibility and reliability of the Pediatric Asthma kNowleDge and mAnagement (PANDA) questionnaires that we developed. Methods We developed 3 questionnaires aimed for Children, Teenagers and Parents of children living with asthma. Experts in childhood asthma reviewed the questionnaires to evaluate face and content validity with a measure of the Scale-Content Validity Index (S-CVI). Children age 7 and up and their parents participated in the feasibility and reliability assessment. Reliability was assessed by doing a test re-test, using the Intraclass Correlation Coefficient (ICC), for each questionnaire topic. Results Face validity was validated for the three PANDA questionnaires with a satisfactory length and comprehension level. Content validity, with a total S-CVI of 0.91, was found for the Children and Parents questionnaires. With 84 participants, the ICC were found to be higher than 0.7 with a 95%CI [0.5-0.9] for the total scores and higher than 0.5 for each topic for each questionnaire, indicating reliability. Conclusion Face and content validity and reliability of the PANDA questionnaires was established, with an appropriate comprehension level and length. Other types of validation like construct validity and responsiveness would need to be assessed to complete the validation of the questionnaires. The PANDA questionnaires could be used for research and in everyday practice.
