Telephone messages regarding preventive measures against COVID-19

Methodological study, in which messages containing text and image were developed through a narrative literature review and whose content was evaluated by eight judges in terms of clarity, practical relevance, theoretical relevance and vocabulary. The content validity index (CVI) was calculated, and messages that reached levels above 90% were considered to have adequate evidence of validity.

Results:

Eighteen text messages/images were developed containing information about COVID-19, hand hygiene, use and handling of masks and the importance of social distancing. After second round of evaluation, a content validity index above 90% was obtained in all evaluated indicators.

Conclusion:

The telephone messages were developed and showedadequate evidence of content validity.
