Abstract Objective The etiology of persistent memory complaints after concussion is poorly understood. Memory perfectionism (highly valuing memory ability and intolerance of minor memory lapses) may help explain why some people report persistent subjective memory problems in the absence of corresponding objective memory impairment. This study investigated the relationship between memory perfectionism and persistent memory complaints after concussion. Methods Secondary analysis of baseline data from a randomized controlled trial. Adults (N = 77; 61% women) with persistent symptoms following concussion were recruited from outpatient specialty clinics. Participants completed the National Institutes of Health Toolbox Cognition Battery, Test of Memory Malingering-Trial 1, and questionnaires measuring memory perfectionism (Metamemory in Adulthood-Achievement subscale), forgetfulness and other postconcussion symptoms (Rivermead Postconcussion Symptoms Questionnaire; RPQ), and depression (Patient Health Questionnaire-2) at M = 17.8 weeks postinjury. Patients with versus without severe memory complaints (based on the RPQ) were compared. Results Memory perfectionism was associated cross-sectionally with severe memory complaint, after controlling for objective memory ability, overall cognitive ability, and depression (95% confidence interval for odds ratio = 1.11–1.40). Sensitivity analyses showed that this relationship did not depend on use of specific objective memory tests nor on inclusion of participants who failed performance validity testing. In a control comparison to test the specificity of identified relationships, memory perfectionism was not associated with severe fatigue (95% confidence interval for odds ratio = 0.91–1.07). Conclusions Memory perfectionism may be a risk factor for persistent memory symptoms after concussion, with potential relevance to the spectrum of functional cognitive disorders more broadly.

记忆完美主义与脑震荡后持续的记忆抱怨有关

摘要 目的 脑震荡后持续性记忆主诉的病因知之甚少。记忆完美主义（高度重视记忆能力和不容忍轻微的记忆失误）可能有助于解释为什么有些人在没有相应的客观记忆障碍的情况下报告持续存在主观记忆问题。本研究调查了记忆完美主义与脑震荡后持续记忆抱怨之间的关系。方法 对来自随机对照试验的基线数据进行二次分析。从门诊专科诊所招募脑震荡后症状持续存在的成年人（N = 77；61% 为女性）。参与者完成了美国国立卫生研究院工具箱认知电池，记忆诈病测试 - 试验 1，以及测量记忆完美主义（成人元记忆 - 成就子量表），健忘和其他脑震荡后症状（Rivermead 脑震荡后症状问卷; RPQ）和抑郁症（患者健康问卷-2）的问卷，时间为 M = 17.8 周受伤后。比较有和没有严重记忆问题的患者（基于 RPQ）。结果 在控制客观记忆能力、整体认知能力和抑郁后，记忆完美主义与严重的记忆抱怨横断面相关（比值比的 95% 置信区间 = 1.11–1.40）。敏感性分析表明，这种关系不依赖于使用特定的客观记忆测试，也不依赖于是否包含未通过性能有效性测试的参与者。在测试已识别关系特异性的对照比较中，记忆完美主义与严重疲劳无关（比值比的 95% 置信区间 = 0.91–1.07）。结论 记忆完美主义可能是脑震荡后持续性记忆症状的一个危险因素，可能与更广泛的功能性认知障碍有关。
