记忆抱怨是军人最常见的认知限制形式，但先前的研究表明，创伤后应激症状（PTSS）可能解释了主观认知抱怨与客观认知表现之间的联系。这种关系背后的机制在很大程度上是未知的，包括这一发现是否适用于记忆抱怨和表现，涉及哪些临床维度，以及当记忆抱怨不可信时，这种关联是如何变化的。方法本研究以196名美国军人为样本，通过建立客观记忆表现与合理/不合理的主观记忆抱怨之间的关系模型，然后评估创伤后应激障碍和创伤后应激障碍中常见的临床特征（如抑郁、焦虑和躯体担忧）如何影响这种关联，来解决这些空白。结果总体而言，记忆抱怨与即时回忆和延迟回忆相关，但这两种关联均由ptsd完全介导（95% CI分别为- 0.14,- 0.01；95% CI为- 0.14,- 0.02）。然而，令人难以置信的记忆抱怨与记忆表现的联系并不一致，并且没有观察到PTSS的中介作用。在临床特征中，只有抑郁减缓了ptsd的影响，特别是通过影响ptsd与整体记忆投诉之间的联系（β = - 0.02, SE = 0.004,p< .001）。结论上述结果证实了对主观记忆投诉的军人进行ptsd和抑郁评估的重要性，并强调了针对这些情况的针对性干预可能在管理记忆投诉中发挥关键作用。
ObjectiveMemory complaints are the most common form of cognitive limitation reported by military service members, but prior research suggests that posttraumatic stress symptoms (PTSS) may account for the link between subjective cognitive complaints and objective cognitive performance. The mechanisms underlying this relationship are largely unknown, including whether the finding applies to memory complaints and performance, which clinical dimensions are involved, and how the association varies when memory complaints are non-credible.MethodUsing a sample of 196 US military service members, the present study aims to address these gaps by modeling the relationship between objective memory performance and plausible/implausible subjective memory complaints, then evaluating how the association is influenced by PTSS and clinical traits commonly found within PTSS (e.g. depression, anxiety, and somatic concerns).ResultsOverall memory complaints were associated with immediate and delayed recall, but both associations were fully mediated by PTSS (95% CI −0.14, −0.01; 95% CI −0.14, −0.02, respectively). Implausible memory complaints, however, were inconsistently linked to memory performance, and no PTSS mediation was observed. Of the clinical traits, only depression moderated the impact of PTSS, specifically by influencing the link between PTSS and overall memory complaints (β = −0.02, SE = 0.004,p< .001).ConclusionsThese results corroborate the importance of assessment for PTSS and depression in service members who report subjective memory complaints and highlight how targeted intervention for these conditions may play a key role in the management of memory complaints.
