Description
Summary:As knowledge and attitude towards performing basic life support and using an automated external defibrillator (BLS and AED) contribute equally to improving survival after out-of-hospital cardiac arrest, we aimed to develop a measuring instrument for a validated assessment of schoolchildrens' attitude towards BLS and AED. The objective was to identify, measure, and address pertinent attitude dimensions that influence the intention to actually perform BLS and AED. We conducted a BLS and AED course for seventh and ninth grade students. Students fulfilled pre- and post-course questionnaires on attitude and intention to perform BLS and AED. The measuring instrument was developed with the use of exploratory factor analysis with application of principal component analysis and confirmatory factor analysis with application of structural equation modeling. Measurement invariance across different groups (gender, grades, previous courses) was tested with Wilcoxon signed ranks test and Mann–Whitney U test. Differences in attitude pre- and post-course were evaluated by application of Mann–Whitney U test. The final attitude model consisted of 3 behavioral constructs (self-confidence, positive motivation, and amotivation). Self-confidence was the major construct directly affecting the intention to act. Positive motivation had a negligible direct effect on intention but correlated strongly with self-confidence. The effect of attitude on the intention to help is therefore less complicated than was expected, which relieves the non-professional educators of having to know the specifics of the different behavioral constructs.
