Forcing University students to stay at home has created enormous stress and uncertainty in their daily life.Objective: This study aimed to assess the perceived stress and coping strategies among undergraduate health science students of Jimma University amid the COVID-19 outbreak.Materials and methods: An online cross-sectional survey was conducted involving 337 undergraduate health science students from (...) August to September 5, 2020. The perceived stress scale -10 and Brief-COPE scale were used to assess the level of stress and coping strategies, respectively. Statistical Package for Social Science Version 22 was employed for data analysis. Logistic regression was conducted to identify predictors of high perceived stress.Results: The overall mean [±standard deviation ] age of the participants was 22.88 years. The mean PSS score was 22.16, and high perceived stress was reported in 121 participants. The overall mean coping score was 72.34, and approach coping was the predominantly used strategy for coping with stress. Personal perception of being stressed by the daily number of COVID-19 cases/deaths in Ethiopia, rare online talk/chat with friends, presence of confusion due to the inconsistent strategies developed by the health/government authorities in view of the scientific recommendations, perception of self/family members being at risk of getting sick, decreased household income following the COVID-19 pandemic, practicing denial, self-blame, planning, and religion as means of coping with stress were associated with high perceived stress.Conclusion: Over one-third of the participants had a high level of perceived stress, and the majority of them were practicing effective means of coping with stress.
