METHODS: This study included 1175 Chinese undergraduate students sampled in May 2022 and May-June 2023, right before and after peaks of infections following the end of lockdown policy in China. The participants completed a survey of demographic variables, and three questionnaires 12-item General Health Questionnaire, Positive Psychological Capital Questionnaire, and Prosocial Tendencies Measure. RESULTS: The participants sampled in 2023 have significant lower GHQ scores and higher PPQ scores than those sampled in 2022, while there is no significant difference in PTM scores between them. The proportion of participants with GHQ-12 scores exceeding 12 in 2023 showed slightly decrease compared to that in 2022. The infection of significant others, the sense of hope, and PPQ self-efficiency, hope and optimism subscale scores were significantly associated with GHQ-12 scores in 2023, but actual infection or quarantine experience were not. CONCLUSIONS: The mental health and psychological capital of the university students have been significantly improved within a year. It is worthy to pay attention to the infection of significant others, the sense of hope, and psychological capital in a pandemic to improve the mental health of university students.
