There is cumulating evidence that working memory (WM) processing is impaired in individuals suffering from a psychosomatic and a psychological disorder. However, it is unclear how repetitive negative thinking (RNT), depressive symptoms, and patient characteristics (i.e., age and incapability to work) contribute to WM impairments. The present study examines how these factors affect WM performance in highly distressed adult psychosomatic inpatients.
Seventy-six inpatients ( = 52.7, SD = 8.4) from a psychosomatic rehabilitation clinic performed a two-block WM updating task, with accuracy and reaction time as indicators of WM functioning.
Multivariate mixed effect model results show that accuracy and reaction time significantly decreased from WM Block 1 to WM Block 2. Higher levels of RNT, more severe depressive symptoms and higher age were associated with worse WM accuracy in Block 1. None of these variables were significantly associated with WM reaction time (in Block 1).
From a clinical perspective, the results suggest that screening for the presence of high RNT levels, severe depressive symptoms or higher age may help to identify patients with impaired WM functioning and to intervene on these important patient characteristics early in the rehabilitation process.
有越来越多的证据表明,患有身心疾病和心理障碍的个体在工作记忆(WM)处理方面存在受损情况。然而,尚不清楚重复性消极思维(RNT)、抑郁症状以及患者特征(即年龄和工作能力丧失)如何导致工作记忆受损。本研究考察了这些因素如何影响高度痛苦的成年身心疾病住院患者的工作记忆表现。
来自一家身心康复诊所的76名住院患者(平均年龄=52.7,标准差=8.4)进行了一个两阶段的工作记忆更新任务,以准确性和反应时间作为工作记忆功能的指标。
多变量混合效应模型结果显示,从工作记忆第一阶段到第二阶段,准确性和反应时间显著下降。较高水平的重复性消极思维、更严重的抑郁症状以及较高的年龄与第一阶段较差的工作记忆准确性相关。这些变量均与工作记忆反应时间(第一阶段)无显著关联。
从临床角度来看,结果表明筛查高水平的重复性消极思维、严重的抑郁症状或较高的年龄,可能有助于识别工作记忆功能受损的患者,并在康复过程早期针对这些重要的患者特征进行干预。
