The costs associated with traumatic injury are often exacerbated by the development of post-traumatic stress symptoms. However, it is unclear what decreases the development of post-traumatic symptoms over time. The aim of the present research was to examine the role of psychological symptoms and social group memberships in reducing the development of post-traumatic stress symptoms after orthopaedic injuries (OIs) and acquired brain injuries (ABIs).
A longitudinal prospective study assessed self-reported general health symptoms, social group memberships, and post-traumatic stress symptoms among participants with mild or moderate ABI (n= 62) or upper limb OI (n= 31) at 2 weeks (T1) and 3 months (T2) after injury.
Hierarchical regressions revealed that having fewer T1 general health symptoms predicted lower levels of T2 post-traumatic stress symptoms after OI but forming more new group memberships at T1 predicted lower levels of T2 post-traumatic stress symptoms after ABI.
A focus on acquiring group memberships may be particularly important in reducing the development of post-traumatic stress symptoms after injuries, such as ABI, which result in long-term life changes.
创伤后应激症状的发展常常使与创伤相关的成本恶化。然而，目前尚不清楚是什么随着时间的推移降低了创伤后症状的发展。本研究旨在探讨心理症状和社会群体成员身份在减少骨科损伤（OI）和获得性脑损伤（ABI）后创伤后应激症状发展中的作用。
一项纵向前瞻性研究评估了轻度或中度 ABI（n=62）或上肢 OI（n=31）参与者在损伤后 2 周（T1）和 3 个月（T2）时的自我报告一般健康症状、社会群体成员身份和创伤后应激症状。
分层回归显示，T1 一般健康症状越少，预测 OI 后 T2 创伤后应激症状水平越低，而 T1 时形成更多新的群体成员身份则预测 ABI 后 T2 创伤后应激症状水平越低。
在减少创伤后应激症状的发展方面，特别是在因 ABI 等导致长期生活变化的损伤后，关注获得群体成员身份可能尤为重要。
