Purpose: Communication among healthcare providers, caregivers and children with asthma is challenging and sometimes may exclude the child. This may result in delay in recognizing and responding appropriately to asthma symptoms. The purpose was to test an instrument's subscale for content validity related to communication with the healthcare provider by examining age appropriateness, readability and clarity for children with asthma. Design and methods: This was a mixed method explanatory sequential design to examine age appropriateness, readability and clarity for a 15-item subscale of an instrument for children. The qualitative arm (focus groups) was used to enrich the questionnaire. The sample included children ages 8 to 12 with asthma (N = 25). Results: The perspective of children with asthma provided enriched information to influence the development of instrument subscale on communication. Conclusions: The subscale revealed internal consistency with Cronbach Alpha 0.85. One of the children reported that using the term provider was clearer as oppose to healthcare provider. Children participating in the study found readable and dear. A readability analysis revealed the items were readable at a 6th grade level. Practice implication: Although the instrument is designed for primary care providers (physicians, nurse practitioners, physician assistants), the information gained from this pilot increases understanding about including the child in a triadic discussion. Further research will lead to next step toward computing reliability of the full measure and a factor analysis. (C) 2019 Elsevier Inc. All rights reserved.
