Development and Validation of the Content of a Mobile Digital Board-Game Application, Constituting a Playful Tool for the Management of Friction Injuries.

Objectives: This study aimed to develop and validate the content of an educational board game aimed at training nurses in the management of friction injuries. Methods: For the development of the game, the Contextualized Instructional Design model was adopted, encompassing the phases of analysis, planning, development, and implementation. The validation of the Friction Care game content involved the participation of 50 expert nurses, who applied the Delphi Technique. Data analysis was conducted using the Content Validity Coefficient (CVC), with the aim of ensuring the consistency and relevance of the proposed items. Results: In the first evaluation round, the judges rated the game's content as ranging from "inadequate" to "fully adequate." After corrections based on the suggestions received, the material was resubmitted for analysis and then considered between "adequate" and "fully adequate." The CVC ranged from 0.94 to 1.0 in the first evaluation and from 0.99 to 1.0 in the second, demonstrating high agreement among experts regarding the quality of the content. Conclusions: The game development and validation of the Friction Care game demonstrated its suitability as an educational resource for training nurses in the management of friction injuries.
