Abstract: Objective: To understand the insomnia disorders of patients with spinal cord injury, and to construct a preliminary model of insomnia disorders. Methods: Using a convenient sampling method, a questionnaire survey was performed on 130 hospitalized patients with spinal cord injury. The questionnaires included: post-traumatic stress disorder screening form, generalized anxiety scale, patient health questionnaire, depression scale, and insomnia severity index. The structural equation method was used to construct the structural equation model of insomnia disorder in patients with spinal cord injury, and the mechanism of various factors was explored. Results: The score of insomnia severity index for patients with spinal cord injury was （16.461 ± 8.022）, of which 75 patients (57.7%) had moderate to severe clinical insomnia. Post-traumatic stress disorder had the greatest impact on insomnia, and depression had a stronger effect on insomnia than anxiety. Conclusion: A scientific and accurate management model should be established to improve the insomnia disorder of patients with spinal cord injury, and pay attention to the post-traumatic stress disorder of patients. Meanwhile, individualized intervention measures should be taken to improve the adverse psychological state of patients and alleviate the insomnia disorder.
