Rafael de Lima Carmo, Evandro Luiz Panho, Christian Antônio Zago de Quadros and 5 others
PMID 37820160WHAT IT FOUND
Ten laypeople and ten nurses rated a 14-scene storyboard for a layperson CPR video as clear and acceptable.
The paper does not show the video improves bystander CPR or survival.
Key findings
01The storyboard had 14 scenes and was rated by 10 lay judges and 10 expert judges.
02Mean Content Validity Index scores were 0.97 for lay judges, 0.90 for expert judges, and 0.94 overall, above the 0.78 threshold used.
03The study did not include functionality or usability testing, so it did not show whether users can understand and use the video correctly.

What it does not show
The study validated a storyboard, not the final video's functionality or usability. Only 20 judges rated the material, and lay judges were recruited from researchers' social context by snowball sampling. Expert judges were all nurses, despite criteria allowing doctors, so medical perspective was absent. The actors were young, while the paper notes cardiovascular conditions have higher incidence in 60 to 69 year old adults. The study did not test whether viewers can perform chest compressions correctly or whether it improves survival.
Declared interests
The project was financed by the Federal University of Fronteira Sul under Public Notice 121/GR/UFFS/2021, registration PES-2021-0222. The supplied text gives funding but no commercial conflict-of-interest statement.
The easy way to misread this
Do not read mean scores of 0.97 and 0.90 as proof that the video teaches effective CPR. The study rated a storyboard's clarity and content, not functionality, usability, or patient outcomes.
