The questionnaires were used to measure nurses’ professional identity, mental health, and sleep quality. Logistic regression analyses were used to explore their relationships.ResultsThe multiple logistic regression analysis suggested that medical assistance, PSQI score, and level of professional identity were independent risk factors for anxiety, and the results of multiple logistic regression analysis suggested that a medium level of professional identity and the PSQI score were independent factors for depression.DiscussionThe results show that nurses’ professional identity is negatively related to anxiety and depression after experiencing the COVID-19 public health emergency.Implications for practiceAfter the COVID-19 public health emergency, managers urgently need to pay attention to nurses’ mental health issues, which may help improve nurses’ professional identity, increase their work enthusiasm, and benefit their career development.
