The Adolescent Asthma Self-Efficacy Questionnaire (AASEQ) has demonstrated validity and reliability in assessing adolescent asthma management, according to a study published in the European Respiratory Journal.

This study included 243 adolescents aged 12 to 18 years who were recruited in England between 2015 and 2016 and who had been diagnosed with asthma by a physician. To form the questionnaire, researchers conducted interviews with participants and performed a literature review.

To assess validity, participants completed 2 scales (KidCope and the General Self-Efficacy Scale). Redundant items were identified through principal components analysis and removed, while internal reliability was assessed using Guttman’s split-half coefficient and Cronbach’s ? coefficient. Pearson’s bivariate correlations were used to investigate construct validity.

The study researchers concluded that “the AASEQ is a reliable and valid tool to use with adolescents with asthma and further work on responsiveness of the scale to interventions and validity in relation to objective measures of asthma management should now be conducted. With self-efficacy being important in the management of long-term conditions, the AASEQ should be useful in assessing adolescent asthma self-management. It should be a useful surrogate endpoint to assess the impact of interventions designed to optimize asthma self-management.”
