Abstract
We previously reported the relationship between anxiety tendencies （STAI） and sleep quality （PSQI） in dental hygiene school students during clinical observations. However, there has been limited detailed investigation into the relationship between STAI, which is part of an anxiety tendency, and Epworth Sleepiness Scale （ESS） and Athens Insomnia Scale （AIS）, which are part of sleep surveys. Therefore, we conducted this study and report our findings herein. Our study included 105 female healthy students with an average age of 20.1 years （ranging from 18 to 45 years old）. Each participant was tested before and after clinical practice for STAI, and before practice for ESS and AIS. The reference values were set at 48.6 points for trait anxiety, 45.9 points for state anxiety, 11 points for ESS, and 6 points for AIS. We found a correlation coefficient of 0.49 between trait anxiety and state anxiety before practice, but no correlation was observed after practice. Notably, the high ESS and AIS group （n＝12） exhibited a strong positive correlation of 0.81 between trait anxiety and state anxiety before practice （P＜0.05）. Therefore, to mitigate state anxiety during clinical observations, it is advisable to proactively identify high ESS and AIS groups and provide sleep education.
