Secondary prevention in coronary artery disease: development and content validity of educational messages for mobile phones.
Lucas Verzegnassi Vieira, Vinicius Lino de Souza, Alba Lúcia Bottura Leite de Barros and 5 others
PMID 36705551WHAT IT FOUND
Coronary patients rated information about preventing another heart problem as very important, especially medicines, emergency signs and heart function.
Mobile-phone messages were checked by experts, but no patient outcomes were tested.
Key findings
01The 67 patients rated every information-need domain as important to very important, especially medicines, emergency signs, heart function and diagnosis/treatment.
02Thirty templates were developed in eight domains to address the patients' information needs.
03Ten experts rated the message domains as adequate for clarity, relevance, font, images and image-text relationship, meeting recommended thresholds.

What it does not show
Only 67 patients from one public hospital in São Paulo were surveyed, and the paper notes the patients generally had low income, so information needs may not match other settings. The messages were only checked by 10 experts; they were not tested with patients for understanding, nor were outcomes such as medication adherence, lifestyle change or cardiovascular events measured. Experts were selected based on the researchers' prior knowledge, not a formal recruitment method. The study reports content validity, not effectiveness.
The easy way to misread this
Do not read this as evidence that the messages improve medication adherence, lifestyle or cardiovascular outcomes. The study only assessed patients' information needs and expert content validity; it did not test the messages with patients.
