Sign language instrument for assessing the knowledge of deaf people about Cardiopulmonary Resuscitation.
Nelson Miguel Galindo-Neto, Magno Batista Lima, Lívia Moreira Barros and 2 others
PMID 32520239WHAT IT FOUND
A sign-language video and printed tool was built to check what deaf people know about CPR.
Deaf users found it understandable, and experts agreed the questions covered recognition, calling for help, and compressions.
Key findings
01The instrument paired a Libras video with a printed answer form and covered identifying cardiac arrest, calling for help, and chest compressions.
02Deaf participants found every question understandable and offered no suggestions for changing the instrument.
03Experts accepted all questions for content, and the instrument showed high consistency across items.

What it does not show
The deaf samples came from three educational institutions, so deaf people outside school settings may respond differently. Of 360 enrolled students, 247 were excluded because they were absent, so the analysed group may not represent all deaf students. The 16-deaf review used a convenience class, and the 113-deaf application included only students present on the collection day. The experts were all nurses, recruited through institutions and snowballing, so their views may not represent all CPR educators. The paper reports validation of content and internal consistency, not a trial of CPR education, CPR skill, or patient outcomes.
The easy way to misread this
Do not read this as evidence that teaching CPR through sign language improves survival. The study only built and checked an assessment tool. It did not measure CPR performance or cardiac arrest outcomes.
