摘要

Background

Post-traumatic stress disorder (PTSD) has a profound impact on the physiological, psychological, social functioning, and occupational development of young and middle-aged spinal cord injury (SCI) patients, with a multitude of factors influencing its manifestation. However, the majority of current studies treat all spinal cord injury patients as a homogeneous group, thereby ignoring the intrinsic characteristics of patients and the inter-individual heterogeneity that exists. The aim of this study was to identify distinct subgroups of young and middle-aged SCI patients according to their PTSD symptom severity and to explore the factors affecting different subgroups.

Methods

A cross-sectional study was conducted at a tertiary level Chinese hospital in Zhengzhou, China. A total of 240 young and middle-aged spinal cord injury patients completed the Sociodemographic questionnaire, Post-traumatic stress disorder self-assessment scale(PCL-C), Perceived social support scale PSSS Simplified Coping Style Questionnaire and Event Related Rumination Inventory ERRI The objective of this study was to identify potential categories of PTSD symptom severity in young and middle-aged spinal cord injury patients. To this end, latent profile analysis (LPA) was employed to ascertain the underlying categories, while multivariate logistic regression was utilized to explore the factors influencing these categories.

Results

Three potential categories were identified: low-level PTSD symptom group(61.3%),medium-level PTSD symptom group(21.7%) and high-level PTSD symptom group(17.0%). The results of the multivariate logistic regression analysis indicated that patients who were self-funded, had comorbidities, demonstrated poor disease awareness, exhibited a low level of self-care, displayed a high level of rumination thinking, and adopted negative coping styles were more likely to be categorized in the high-level PTSD symptom group. Conversely, patients who had good social support and adopted positive coping styles were more likely to be categorized in the low-level PTSD symptom group and medium-level PTSD symptom group.

Conclusions

PTSD symptom severity in young and middle-aged spinal cord injury patients is characterized by substantial heterogeneity. A number of factors may influence the potential categories of PTSD symptom severity in young and middle-aged spinal cord injury patients, including the patient’s form of medical payment, the occurrence of complications, disease awareness, level of self-care, positive and negative coping strategies, social support, and rumination thinking. The findings of this study may serve as a new reference point for the implementation of different intervention and prevention strategies for patients.
