PMID 35485628WHAT IT FOUND
Expert review and adolescent wording checks showed CPR knowledge and attitude tools may be usable for 11-13 year olds, but further testing is needed.
Key findings
01Two of eight knowledge questions scored above 0.92, six scored 1, and the overall knowledge content validity index was 0.98.
02Two of eleven attitude questions scored above 0.85, nine scored 1, and the overall attitude content validity index was 0.98.
03Thirty adolescents suggested wording changes, including replacing 'absence' with 'lack' and 'sudden' with 'abrupt', to improve understanding.

What it does not show
Expert judges were chosen by convenience, and only 14 of 15 invited specialists agreed to participate. Only content validity and adolescent wording were checked; the authors state that psychometric validation is still needed. The adolescent sample was small and limited to ages 11 to 13 years, so results may not apply to other age groups. Some interviews were online because of pandemic confinement, which may have affected understanding checks. Adolescents had difficulty with CPR-specific vocabulary.
The easy way to misread this
Do not read the high content validity scores as proof that the instruments are psychometrically validated or that they can measure real CPR skill. The study only checked expert judgment and adolescent wording; the authors state that psychometric validation is still needed.
