Cardio-Pulmonary Resuscitation (CPR) in Children Between 5 and 8 Years Old: Psychometric Properties of Nonide Scale.

Background: Early intervention in a cardiorespiratory arrest by a witness significantly increases survival. That is why early training in cardiopulmonary resuscitation (CPR) may be essential. Therefore, the aim of this study is the development and validation of an instrument to assess CPR knowledge and skills for schoolchildren from 5 to 8 years old.

Method: We used a Spanish sample with 164 children aged between 5 and 8 years old. These children received a workshop called the "CPR from my school" program and their knowledge of CPR was assessed pre- and post-Workshop. We examined the scale through psychometric analyses within the framework of Classical Test Theory.

Results: The Nonide Scale provided evidence of content validity, revealed an essentially unidimensional internal structure, as well as excellent reliability (Ω = .87). Furthermore, a significant improvement was observed in scores, before and after the CPR Workshop.

Conclusions: The Nonide Scale, designed to measure CPR knowledge and acquired skills in children from 5 to 8 years old, shows adequate psychometric properties, hence it can be used as professional and research contexts require.
