Although posttraumatic stress disorder (PTSD) after acquired brain injury (ABI) is relatively common, its causal mechanisms remain speculative and little research has considered psychological perspectives. The current study aimed to examine whether metacognitive variables were associated with posttraumatic stress symptom (PTSS) severity in individuals with an ABI.
Participants who had a traumatic brain injury (n = 47) or subarachnoid haemorrhage (n = 93) completed questionnaires related to demographic, clinical, social support and metacognitive variables. Correlation analyses and a hierarchical multiple regression analysis, with total PTSS severity used as the outcome variable, were conducted.
Results demonstrated that metacognitive factors were correlated with PTSS severity and were able to explain an additional and significant amount of variance in PTSS severity within the regression analysis.
The results provide preliminary support that metacognitive variables are associated with PTSS after ABI. Clinical implications within rehabilitative settings are discussed, as well as theoretical and research implications in the context of the study's limitations.
Posttraumatic stress disorder (PTSD) can impede quality of life after brain injury. Clinical, social and metacognitive processes all influence the development of PTSD after brain injury and should be considered within rehabilitative care plans. Rehabilitative care plans should incorporate interventions for PTSD when appropriate, and metacognitive interventions could prove beneficial.
尽管后天性脑损伤（ABI）后创伤后应激障碍（PTSD）相对常见，但其因果机制仍属推测，且很少有研究考虑心理学视角。本研究旨在探讨元认知变量是否与ABI患者的创伤后应激症状（PTSS）严重程度相关。
患有创伤性脑损伤（n = 47）或蛛网膜下腔出血（n = 93）的参与者完成了与人口统计学、临床、社会支持和元认知变量相关的问卷调查。进行了相关分析和分层多元回归分析，以PTSS总严重程度作为结果变量。
结果表明，元认知因素与PTSS严重程度相关，并且在回归分析中能够解释PTSS严重程度中额外的显著方差量。
结果提供了初步支持，即元认知变量与ABI后的PTSS相关。讨论了康复环境中的临床意义，以及在研究局限性背景下的理论和研究意义。
创伤后应激障碍（PTSD）会妨碍脑损伤后的生活质量。临床、社会和元认知过程都会影响脑损伤后PTSD的发展，应在康复护理计划中予以考虑。康复护理计划应在适当的时候纳入针对PTSD的干预措施，元认知干预可能会被证明是有益的。
