Development and Content Validation of a Manga-Based Educational Technology on Child Sexual Abuse: A Nursing Tool for Health Literacy in Brazil

As child sexual abuse remains a pervasive and silent crime, there is an urgent need for innovative nursing tools that enhance health literacy to empower young populations. The objective of this study was to develop and validate a manga-based nursing educational technology aimed at child sexual abuse prevention and health literacy in Brazil. Regarding the method, a methodological study with a quantitative approach was conducted to validate the content of the manga , which was designed as a nursing information tool using ibisPaint software. The material was evaluated by 12 experts in child health, protection networks, and information technology who met Jasper’s criteria with validation analyzed using the Content Validity Index (CVI) at an acceptable agreement rate of 90%. Additionally, Gwet’s AC2 was used for intra-expert agreement evaluation. The results revealed a CVI of 1.00 for objectives and relevance, while the structure of the manga achieved a CVI of 0.97 with a clarity rating of 0.92. Gwet’s AC2 indicated almost perfect agreement, yielding values of 0.92 for objectives, 0.84 for structure, and 0.93 for relevance. In conclusion, this validated manga serves as an effective nursing educational technology that facilitates health literacy by providing children and adolescents with the necessary autonomy to recognize abuse and access protection networks. This research contributes a rigorous technological framework to nursing informatics, offering a culturally relevant instrument for promoting social justice and child protection in the Brazilian context.
