[Can We Train the Chain of Survival While Playing? Validation of the Tool «Rescube»].

Purpose: To validate the content and adequacy of the "Rescube" training material that includes adapted information from the chain of survival. Material and methods: The study included three steps: (i) material development by 7 experts, following Delphi method; (ii) assessment of training material by 11 experts by means of a Likert score and calculation of content validity; and (iii) pilot study in two groups of 5 to 8 years-old: Rescube group (GR; n =60) and Traditional group (GT; n =60). GR was trained with Rescube and a Teddy bear, while GT was traditionally trained with a pediatric manikin. Participants were individually assessed at baseline, and one week and one month after training. Results: All content validity indexes calculated are above the recommended cut-off for analysis with more than 9 experts (>= 0,80). Children's learning results were positive, with percentages equal or higher than 80% in all registered variables at the first (one week) evaluation and equal or higher than 67% when evaluated one month after training. No significant differences were detected between groups. Conclusion: The Rescube training tool based on infantile pictures is valid and useful to train young schoolchildren in the chain of survival.
