The objective of this investigation was to ascertain the correlation between stress and the prevalence of RAS during the COVID19 pandemic. This investigation employed a cross-sectional design and was observational analytic. A total of 104 research subjects were included in the study, which was conducted on students at SMA Negeri 6 in Yogyakarta. The results revealed 59 respondents with normal stress levels, of which 57 respondents (54.8%) were positive for RAS. The Spearman Rank correlation statistical test was employed to analyze the data, resulting in a significant value of p = 0.019 or 0.05, which denotes a correlation stress and the occurrence of RAS during the COVID-19 pandemic in students at SMA 6 Yogyakarta, serving as the conclusion]]>
