Preventive Behavioral Insights for Emerging Adults: A Survey during the COVID-19 Pandemic.

Emerging adulthood is an important period for establishing health behavior patterns in life. This study aimed to examine factors related to preventive behaviors of emerging adults during the COVID-19 pandemic. A descriptive online survey design was used. Data were collected using a self-administrated, 28-item questionnaire completed by 239 undergraduate students from a university in Seoul, South Korea. The questionnaire was developed based on previous studies and the guidelines of the World Health Organization about COVID-19 preventive behaviors. The mean age of participants was 21.97 years, and the average score for COVID-19 preventive behaviors was 4.13 (SD: ±0.42) on a 5-point scale. Hierarchical regression analyses revealed that subjective norms related to parents (β = 0.425, p < 0.001), issue involvement related to COVID-19 (β = 0.160, p = 0.024), and sex (β = 0.137, p = 0.029) were significant factors related to preventive behaviors of emerging adults after controlling for demographic characteristics. The variables explained 20.1% of the variance in preventive behaviors. The results of this study suggest that better strategies for subjective norms related to parents and issue involvement related to COVID-19 must be considered to improve emerging adults' preventive behaviors.
