Abstract :
Everyone has a risk factor for being infected with COVID-19, adolescents
have a lower risk factor than the elderly but usually adolescents do not cause
serious symptoms when infected with COVID-19, so the prevalence of data from
adolescents is underestimated, this can trigger the spread of COVID-19
increasingly large. This study aims to determine the effect of education given to
adolescents regarding the prevention of transmission of COVID-19. This research
is a true experimental research with a pretest posttest control research design. The
number of samples in this study were 82 adolescents from 112 populations, the
samples were divided into two groups, namely the control group and the
experimental group. The experimental group was the group that received
treatment, while the control group was the group that did not receive treatment or
education. This sampling technique uses multistage clutser sampling technique.
Data were collected using a pretest and posttest questionnaire to both groups. The
results of this study indicate the effect of education on knowledge by providing an
effect size of 72.3% and indicate a significant difference between the
experimental group and the control group.
