Development, Validation and Translation of Cardiopulmonary Resuscitation and Automated External Defibrillator Training and Placement Bilingual Questionnaire

Abstract

Objectives: The paper describes the development and translation of a questionnaire purported to measure (1) the perception of the placement strategy of automated external defibrillator, (2) the perception on the importance of bystander cardiopulmonary resuscitation and automated external defibrillator (3) the perception on the confidence and willingness to apply these two lifesaving interventions as well as (4) the fears and concerns in applying these two interventions.For construct validation, iterative runs of exploratory factor analysis was performed using principal axis factoring and promax oblique rotation.Results Five factors with eigenvalue >1 were identified. Pattern matrix analysis showed that all items were loaded into the factors with pattern coefficient value >0.4. One item was subsequently removed as Cronbach's alpha >0.9 which indicates redundancy. After removing the item, the Cronbach's alpha values of all factors were still good, ranging from 0.8 to 0.9. Intra-class correlation coefficient was 0.831.

“…The reliability and validity were tested using four different methods: the factor loading, Cronbach's alpha, composite reliability, and average variance extracted (AVE). According to Chew et al (2019), the values of the variables in factor loading found to be less than 0.7 should be avoided unless they are essential for validity contents. Thus, the threshold value was determined as 0.6.…”

Development validation and evaluation of the knowledge test on cardiopulmonary resuscitation and correct use of the automated external defibrillator in Asunción 2023

“…The difficulty of the KOR-AED items varied, with certain items showing a medium level of difficulty, especially the questions related to the use of the AED and others a higher discriminatory index, In addition, Cronbach's alpha of 0.75 indicates an acceptable internal consistency of the KOR-AED test, however other studies of development and validation of questionnaires in CPR and AED use showed a Cronbach's alpha of 0.84 (11) and 0.9 (12) attributable to social contexts and familiarity with the use of the AED other than our own.…”
