RECRUITMENT
Studies have suggested that CPR education intervention may positively affect a bystander’s attitude toward CPR, intention to perform CPR, knowledge, and skill performance [Previous studies have reported that the average retention length of CPR knowledge and skill was 3 months after an education intervention [Future studies may wish to investigate the length of CPR performance between non-intervention and frequent intervention groups. Examining the effects of newly developed CPR education approaches and VR techniques may reveal ways to improve public accessibility to CPR education during period of global uncertainty, such as with the COVID-19 pandemic. Also, considering the benefit of operating new teaching method and technology may reduce the numbers of educators in each teaching session or can become remotely accessing each session and allow more students to participate.Two limitations were noted while conducting in this study. First, public fear due to a spike in COVID-19 cases caused a high drop-out rate in the follow-up observation that led to underpower sample size. Second, the target population was composed entirely of university students who may have already been exposed to CPR or first-aid information before. Although the recruitment process followed randomized approach, the discrepancy in gender and age in each group should be improved in further study. Future studies should consider recruiting participants from a more diverse range of backgrounds or age groups.
