The descriptive statistics, Pearson correlations, and hierarchical regression analysis were used to examine the results. Results (1) The social trauma was positively associated with depression, whereas the optimism was negatively associated with social trauma, and depression; (2) The social trauma had a significant correlation with depression, and the optimism could moderate the relationship between social trauma and depression.
