title: Development and evaluation of an instrument to measure reasoning about managing asthma in older school-age children and adolescents.
abstract: OBJECTIVE
  This article describes development and evaluation of a 4-scenario instrument designed to measure reasoning abilities for managing asthma symptoms.
  
  
  METHODS
  Existing literature informed creation of a reasoning template and the reasoning scenarios. Think-aloud interviews appraised scenario functionality. Experts assessed content validity. Data from 2 groups of students with asthma aged 9-15 years (N = 132 and 307) were used to evaluate psychometric properties.
  
  
  RESULTS
  The scenarios were deemed functional, content was relevant, and readability was age/grade appropriate. Cronbach's alpha was 0.79. Exploratory and confirmatory factor analyses indicated a single component solution and revealed a good fit. Concurrent validity was established using correlations with asthma knowledge.
  
  
  CONCLUSIONS
  The instrument could be used to assess reasoning about symptom management and to evaluate educational interventions.
