身体知觉的改变与抑郁症有关，但对这种疾病中身体知觉的程度和准确性却没有详细的经验描述。本研究探讨了客观准确性的心跳知觉（使用Schandry的精神跟踪任务）和身体的重点（使用身体意识问卷; BCQ）在健康对照志愿者，中度抑郁症的社区样本，和更严重的抑郁症的诊所样本（n = 18，每组）的主观程度。正如预期的那样，社区样本显示出比对照组更不准确的心跳感知。然而，与预测相反，在Schandry任务中，抑郁程度更严重的诊所样本比社区抑郁样本表现得更好，并且与对照志愿者相当。在主观身体意识上没有组间差异。抑郁症的理论的影响进行了讨论。(c)2006爱思唯尔有限公司保留所有权利。
Alterations in bodily awareness have been implicated in depression but there has been little detailed empirical characterisation of the degree and accuracy of body perception in the disorder. The present study examined the objective accuracy of heartbeat perception (using the Schandry mental tracking task) and the subjective degree of bodily focus (using the Bodily Consciousness Questionnaire; BCQ) in healthy control volunteers, a moderately depressed community sample, and a more severely depressed clinic sample (n = 18 in each group). The community sample showed less accurate heartbeat perception than the control group as expected. Counter to prediction, however, the more severely depressed clinic sample performed better than the community depressed sample and equivalently to control volunteers on the Schandry task. There were no group differences on subjective bodily awareness. Implications for theories of depression are discussed. (c) 2006 Elsevier Ltd. All rights reserved.
