Abstract

Objective: to prepare a reliable tool in order to measure the self-efficacy of Cardiopulmonary Resuscitation (CPR) students after previous training.
Method: a study for preparation and validation of a tool: development, aspect and contents validity, construct validity. The first source for collecting the items which would form the self-efficacy scale consisted in a questionnaire including 14 semi-structured questions and five clinical cases on CPR and cardiac arrest, which had to be completed by professionals with CPR training. These items were classified into three scales, and were validated by experts in terms of aspect and contents. Two different samples were used for construct validity (85 students in the first stage and 101 in the second stage). Descriptive analysis was conducted, as well as reliability analysis through Cronbach’s alpha coefficient; an exploratory factor analysis was also conducted. The SPSS statistical program, version 19.0, was used for analysis.
Results: in the first stage, the Self-efficacy Scale A obtained a 0.91 Cronbach’s alpha coefficient; in the second stage, Scale A achieved a 0.93 Cronbach’s alpha. The value obtained with the total population (n= 186) was 0.92, very similar to the one obtained with the total sample. The Self-efficacy Scale for basic CPR had one-dimensional structure and included 20 items. Statistically significant associations were found between cognitive-emotional constructs and the self-efficacy value.
Conclusion: a one-dimensional scale was obtained for self-efficacy in basic CPR. There are emotional and cognitive variables involved as mediators in the resuscitation behaviour.
