Baseline characteristics, Injury Severity Score (ISS), and Post-traumatic Stress Disorder Checklist-Civilian Version (PCL-C) were recorded. PSQI and SCL-90 scores were assessed at the same postoperative time point. ROC analysis was used to evaluate the discriminatory performance and optimal cut-off values of these scores for early clinical identification of PTSD. Correlation analyses examined relationships among PSQI, SCL-90, PCL-C, and ISS. Multivariate logistic regression was used to identify factors independently associated with PTSD. A\n                      <jats:italic>post hoc<\/jats:italic>\n                      power analysis was additionally performed for baseline variables with\n                      <jats:italic>P<\/jats:italic>\n                      &amp;gt; 0.05, and a 1:1 propensity score matching sensitivity analysis was conducted.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The PTSD group had significantly lower proportions of married individuals, those with a bachelor's degree or higher, and those with monthly income &amp;gt;5000 RMB, along with higher ISS and PCL-C scores (all P &amp;lt; 0.05). PSQI and SCL-90 scores were significantly higher in the PTSD group (\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.001). The combined PSQI and SCL-90 model showed the largest area under the curve for PTSD identification (AUC = 0.937, 95%CI: 0.895\u20130.966), with an optimal probability cut-off of 0.462, 89.80% sensitivity, and 84.55% specificity. The optimal cut-off values for PSQI and SCL-90 were 11.5 and 128.5, respectively. PSQI and SCL-90 scores were positively correlated with ISS (\n                      <jats:italic>r<\/jats:italic>\n                      = 0.742 and\n                      <jats:italic>r<\/jats:italic>\n                      = 0.586) and PCL-C scores (\n                      <jats:italic>r<\/jats:italic>\n                      = 0.625 and\n                      <jats:italic>r<\/jats:italic>\n                      = 0.493; all\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.001). Multivariate analysis confirmed that education, monthly income, PSQI score, and SCL-90 score were independently associated with PTSD status (all P &amp;lt; 0.05).
