Construction and Validation of a Podcast for the Prevention of Metabolic Syndrome in Adolescents

Abstract

Objectives: to create a podcast for the prevention of metabolic syndrome in adolescents and to validate its content, face and agreement with the target audience. Method: a methodological and quantitative study carried out in three stages from August 2022 to November 2023, after approval by an Ethics Committee. Stage 1: Pre-production - Construction of the storyboard based on a validated booklet and the principles of the Cognitive Theory of Multimedia Learning. This was followed by content validation with 22 nurses that are experts in adolescents' health, using the Health Education Content Validation Instrument. Stage 2: Production - adjustments and recording. Stage 3: Post-production: face validation with 12 nurses that are experts in the construction of educational technology, using a validated instrument and agreement validation with the target audience, using the Educational Podcast Evaluation Instrument. The Content Validity Index, Cronbach's α and Aiken's V were calculated and considered valid for values ≥0.80, ≥0.70 and ≥0.81, respectively. Results: the global Content Validity Index for the storyboard was 0.985, and 0.985 for face, with Cronbach's α values of 0.896 and 0.901, respectively. In the agreement validation with the target audience, Aiken's V was greater than 0.81 for 18 of the 20 items in the Educational Podcast Evaluation Instrument. Conclusion: the podcast can be considered valid in terms of content, face and agreement with the target audience and may be used for health education in the prevention of metabolic syndrome in adolescents.
