Abstract：  Objective: Identify the acute stress response patterns, and explore the difference of state anxiety and positive and negative emotion scores of different acute stress response models at different time points. Methods: The acute stress response of 226 healthy adults was induced by the stress inducing task. Salivary cortisol was collected and the trait anxiety scale, state anxiety scale, and positive and negative emotion scale were filled out at different time points. The latent class growth analysis of salivary cortisol was used for heterogeneity testing. Results: The results showed that the acute stress response pattern can be divided into three latent class: low stress response, medium stress response and high stress response. The state anxiety scores and negative emotion scores of individuals with low acute stress response after the end of stress task were significantly lower than those at the end of stress task. Conclusion: The acute stress response pattern has obvious classification characteristics, including low stress response, medium stress response and high acute stress response. Low stress response individuals will experience negative emotional experience for a short time after stress.
