Abstract

Objectives: (1) Examine the relationship between subjective cognitive complaints and objective cognitive functioning in combat veterans; and (2) evaluate conditional effects of posttraumatic stress disorder (PTSD) and deployment-related mild traumatic brain injury (TBI) within that relationship.

Method: Combat veterans (N = 225, 86.22% male) completed a lifetime TBI interview, a structured interview assessing PTSD symptoms, a neuropsychological assessment battery, and a self-report measure of cognitive symptoms.

Results: All correlations between subjective cognitive complaints and objective cognitive measures were not statistically significant. Hierarchical linear regression indicated that cognitive performance was not significantly related to cognitive complaints, but both PTSD diagnosis and history of deployment mild TBI explained a significant amount of unique variance in self-reported cognitive symptoms. Interactions between the studied variables were not significant.

Conclusions: PTSD and history of deployment mild TBI were uniquely related to cognitive complaints, but cognitive test performance was not. No confounding effects of PTSD or deployment mild TBI were observed in the relationship between cognitive performance and cognitive complaints. This provides support that symptom distress may be a better explanatory factor for perception of lower cognitive functioning than actual cognitive performance.

参战老兵的主观认知抱怨和客观认知功能:PTSD和部署轻度TBI的影响。

目的:(1)研究退伍军人主观认知抱怨与客观认知功能的关系;(2)评估创伤后应激障碍(PTSD)和部署相关的轻度创伤性脑损伤(TBI)在这种关系中的条件效应。方法:参战老兵(N = 225, 86.22%为男性)完成了终身TBI访谈、创伤后应激障碍症状评估的结构化访谈、神经心理评估组和认知症状自我报告测量。结果:主观认知抱怨与客观认知测量的相关均无统计学意义。层次线性回归显示，认知表现与认知症状无显著相关性，但PTSD诊断和轻度TBI部署史解释了自述认知症状的显著独特差异。研究变量之间的相互作用不显著。结论:创伤后应激障碍和部署轻度TBI病史与认知主诉有独特的关系，但认知测试表现与认知主诉无关。在认知表现和认知抱怨之间的关系中，没有观察到PTSD或部署轻度TBI的混杂效应。这为症状困扰可能比实际认知表现更能解释认知功能低下的感知提供了支持。

期刊介绍： pplied Neuropsychology-Adult publishes clinical neuropsychological articles concerning assessment, brain functioning and neuroimaging, neuropsychological treatment, and rehabilitation in adults. Full-length articles and brief communications are included. Case studies of adult patients carefully assessing the nature, course, or treatment of clinical neuropsychological dysfunctions in the context of scientific literature, are suitable. Review manuscripts addressing critical issues are encouraged. Preference is given to papers of clinical relevance to others in the field. All submitted manuscripts are subject to initial appraisal by the Editor-in-Chief, and, if found suitable for further considerations are peer reviewed by independent, anonymous expert referees. All peer review is single-blind and submission is online via ScholarOne Manuscripts.
