Development and semantic validation of an instrument for the assessment of knowledge and attitudes towards cardiopulmonary resuscitation in adolescents

Objective. Develop and semantically validate an instrument to assess the knowledge and attitudes of adolescents towards cardiopulmonary resuscitation (CPR)..Methods. Validation study of an instrument to evaluate the knowledge and attitudes of adolescents towards CPR, developed in three phases: (i) development of the evaluation instruments by the authors; (ii) content validation performed by 14 expert judges in the area using the content validity index for analysis; and (iii) semantic validation carried out with the participation of 30 adolescents between 11 and 13 years old. Results. In the content validation, the questions on CPR knowledge obtained a content validity index (CVI) between 0.92 and 1.00, with a general index of 0.98; and the questions about attitudes obtained an IVC between 0.85 and 1.00, with a general index also of 0.98. Regarding semantic validation, three questions were modified in the knowledge assessment instruments and five in the attitude assessment instrument. Conclusion. Semantic and content validation of the instruments studied showed that they are suitable for assessing the knowledge and attitudes of adolescents related to CPR, so their use is recommended in the evaluation of training actions in this population group.
