Objective: to validate the content and appearance of the educational booklet "You can control your child's asthma - let's learn together?" with parents and caregivers of children with asthma.
Methods: this is a methodological study, carried out with 34 mothers and caregivers of children, from two to 10 years old, diagnosed with asthma. The educational booklet validation was performed using Content Validity Index (CVI) and assessment of comprehension, attractiveness, self-efficacy, persuasion, and cultural acceptance domains.
Results: the booklet was considered clear (99.8%) and relevant (100%), with a global CVI of 0.99. Domain assessment proved to be an easy-to-understand tool, culturally appropriate, attractive, with persuasive power and promoting self-efficacy.
Conclusion: the booklet is valid and adequate for promoting the self-efficacy of parents and caregivers in childhood asthma control and management, potentially scalable to other realities of outpatient care.
