Background. Covid-19 is a newly discovered infectious disease that has sparked a worldwide epidemic. The primary endeavour to prevent Covid-19 illness transmission is to adopt the Covid-19 prevention technique. This study aims to determine the factors affecting teenage compliance to the Covid-19 prevention program using the health belief model.

Method. A cross-sectional analytic design was used in this study. Students from Junior High School 06 Satap, South Kalimantan, were recruited for this study. Total sampling was used to choose samples (n=94). The health belief model and Covid-19 preventive compliance questionnaires were used to assess compliance. Somer's d was used to examine the relationships.

Results. The majority of respondents (48.9%) had a low perceived susceptibility, a high perceived severity (69.1%), a high perceived benefit (52.1%), a moderate perceived barrier (68.1%), a moderate cue to action (60.6%), a moderate self-efficacy (73.4%), and moderate compliance with the Covid-19 prevention protocol (69.1%). Additionally, the results demonstrated a substantial correlation between perceived vulnerability, perceived barriers, and self-efficacy in teenagers for Covid-19 preventative regimen compliance (p=0.014; p=0.037; p=0.019, respectively).

Conclusion. There is a strong correlation between perceived vulnerability, reported impediments, and self-efficacy for complying with the Covid-19 preventative program in adolescents.
