Development and content and face validation of an educational flipchart to support arbovirus prevention in primary health care: a methodological study

Abstract Background Arboviral infections remain a major public health challenge in Brazil, particularly in Primary Health Care (PHC), where health education and prevention actions are essential to reduce transmission and community risk. Educational technologies may support PHC professionals by organizing key preventive messages and facilitating communication with the population. This methodological study aimed to develop an educational flipchart for arbovirus prevention in PHC and to obtain evidence of content validity and face validity, the latter referring to judges’ appraisal of the material’s clarity, comprehensibility, relevance, and visual presentation for its intended use. Methods A descriptive methodological study was conducted between July 2022 and February 2023 in three sequential phases: (1) documentary review and qualitative synthesis of official materials to support content development; (2) construction of the flipchart; and (3) content and face validation by 17 judges, including collaborating professionals and second-year residents from a multiprofessional public health residency program. The judges assessed 23 items distributed across four domains: objectives and content, text and language, visual presentation, and relevance, using a 4-point Likert scale. Agreement was summarized using the Content Validity Index (CVI). Results Eight official documents were selected and contributed to the definition of the flipchart content and structure. The final version comprised seven pages and addressed key aspects of arbovirus prevention in accessible language and culturally situated visual design. The validation process showed a CVI of 1.00 for objectives and content, 1.00 for text and language, 0.98 for visual presentation, and 0.99 for relevance. The overall CVI was 0.99. Most suggestions made by the judges were incorporated into the final version of the material. Conclusion The flipchart showed satisfactory evidence of content validity and face validity among the participating judges and represents a potentially useful educational resource for PHC professionals in health education and arbovirus prevention practices. Validation with community members, as well as studies assessing usability and effectiveness, are recommended before broader implementation.
