摘要： Objective This study provides a comprehensive review of the literature on memory impairment and the potential effective factors in patients with chronic pain. Methods A literature search of databases PubMed, EMBASE, SpringerLink, and PsycINFO until September 2012 was conducted using the keywords 'memory' and 'chronic pain'. The study emphasises on publications over the past 20 years. Results Memory impairment in chronic pain patients is substantial, but the aspects of memory (e.g. working memory, long-term memory, and autobiographical memory) in chronic pain patients and the potentially related factors (e.g. age, level of education, pain conditions, emotion, neural network, and use of analgesics) are modest. Memory impairment is interpreted with the attention-narrowing hypothesis and the capacity-reduction hypothesis. Conclusions The currently available data and theory have explained memory impairment in chronic pain patients, but many controversies remain. Future research should focus on the subclinical characteristics of chronic pain, enlarging the sample size, and emphasise on the experimental intervention method and the cognitive neuroscience method. © Scandinavian College of Neuropsychopharmacology 2013.

摘要： Objective: Overgenerality and delay of the retrieval of autobiographical memory (AM) are well documented in a range of clinical conditions, particularly in patients with emotional disorder. The present study extended the investigation to chronic pain, attempting to identify whether the retrieval of AM in patients with chronic pain tends to be overgeneral or delayed. Design: With an observational cross-sectional design, we evaluated the AM both in patients with chronic pain and healthy controls by Autobiographical Memory Test. Pain conditions were assessed using the pain diagnostic protocol, the short-form McGill Pain Questionnaire (SF-MPQ), and the Pain Self-Efficacy Questionnaire (PSEQ). Emotion was assessed using the Beck Depression Inventory-II (BDI-II) and the Beck Anxiety Inventory. Subjects and Settings: Subjects included 176 outpatients with chronic pain lasting for at least 6 months and 170 healthy controls. Results: 1) Compared with the healthy group, the chronic pain group had more overgeneral memories (OGMs) (F=29.061, P<0.01) and longer latency (F=13.602, P<0.01). 2) In the chronic pain group, the stepwise multiple regression models for variables predicting OGM were significant (P<0.01). Specifically, the variance in OGM scores could be predicted by the BDI score (9.7%), pain chronicity (4.3%), PSEQ score (7.1%), and Affective Index (of SF-MPQ) score (2.7%). 3) In the chronic pain group, the stepwise multiple regression models for variables predicting latency were significant (P<0.05). Specifically, the variance in latency could be predicted by age (3.1%), pain chronicity (2.7%), pain duration (4.3%), and PSEQ score (2.0%). Conclusions: The retrieval of AM in patients with chronic pain tends to be overgeneral and delayed, and the retrieval style of AM may be contributed to negative emotions and chronic pain conditions. © 2014 American Academy of Pain Medicine Wiley Periodicals, Inc.
