Insights
A new questionnaire effectively assesses schoolchildren's knowledge of Basic Life Support (BLS) and Automated External Defibrillator (AED) use. This tool helps educators improve vital life-saving skills training for children.
Area of Science:
- Pediatric emergency medicine
- Health education
- Psychometrics
Background:
- Over 60% of cardiac arrests occur outside hospitals.
- International guidelines recommend teaching basic life support (BLS) to children aged 12 and above.
- Validated tools to assess BLS/AED knowledge in schoolchildren are lacking.
Purpose of the Study:
- To construct and psychometrically validate a questionnaire assessing Basic Life Support (BLS) and Automated External Defibrillator (AED) knowledge in primary and secondary school students.
Main Methods:
- A cross-sectional descriptive study involving questionnaire construction (ConocES-BLS/AED).
- Phases included content validation by experts, a pilot test, and psychometric validation using Item Response Theory.
- The study involved 14 experts, 105 students for pilot testing, and 182 students for final validation.
Main Results:
- The ConocES-SVB/AED questionnaire, comprising 12 items, was developed and validated.
- Pilot testing showed good reliability (0.84).
- Psychometric validation confirmed adequate fit and acceptable reliability (0.65), indicating its utility in measuring schoolchildren's BLS/AED knowledge.
Conclusions:
- The validated questionnaire serves as a crucial resource for educators.
- It enables the identification of knowledge gaps in BLS/AED maneuvers among schoolchildren.
- The tool supports the improvement and design of effective educational interventions for pediatric BLS/AED training.
Abstract:
The 60 % of cardiac arrests happen in the out-of-hospital setting. In 2023, the International Liaison Committee on Resuscitation issued a statement entitled "Children save lives", recommending the teaching of basic life support to children from the age of 12. However, we have not identified validated instruments that assess the level of knowledge of schoolchildren about BLS and AED.
Objective:
Construction and psychometric validation of a questionnaire to assess knowledge on Basic Life Support (BLS) and Automated External Defibrillator (AED) in primary to secondary school children.
Method:
Cross-sectional descriptive study of validation of the questionnaire consisting of several phases: construction of the questionnaire on knowledge on BLS and AED (ConocES-BLS/AED), content validation, pilot test and psychometric validation.
Results:
The ConocES-SVB/AED questionnaire was constructed, content validation was carried out by 14 experts, the pilot test carried out on 105 students reported good reliability (0.84), and finally with the psychometric validation a questionnaire composed of 12 items was obtained and psychometrically validated using the Item Response Theory in a final sample of 182 participants. Adequate fit values and acceptable reliability (0.65) were obtained, demonstrating its usefulness to accurately measure the level of knowledge about SVB/AED maneuvers in schoolchildren.
Conclusions:
The created and validated questionnaire provides educators with a fundamental resource to identify areas of lack of knowledge, improve and design effective educational interventions for schoolchildren on SVB/AED maneuvers.
