Abstract

A growing body of research suggests that disrupted interoception plays an important role in various mental disorders, including Obsessive-Compulsive and Related Disorders. However, interoceptive abnormalities in Skin Picking Disorder (SPD) remain unexplored. This study aimed to evaluate and synthesize existing evidence regarding interoceptive disruptions in SPD, adopting a broad definition of interoception encompassing certain types of skin-mediated signals. We searched five databases (PubMed, Scopus, EBSCO, Web of Science, Embase) for articles reporting associations between SPD and any interoceptive modality/dimension. Citation tracking was also conducted. The database search identified 118 articles, and citation tracking additional nine. Eight distinct studies, involving 1338 participants (462 with SPD) met the inclusion criteria. Findings indicated disrupted affective touch processing in SPD. Pain sensitivity did not differentiate individuals with SPD from controls. Limited evidence indicated reduced cardiac interoceptive accuracy and lower emotional awareness in SPD, alongside a link between heightened reliance on bodily signals and decreased control over picking. A post-hoc analysis suggested possible disruptions in itch processing. Overall, preliminary evidence indicates interoceptive disruptions in SPD.

内感觉异常和抠皮障碍：系统综述和初步证据的叙述综合

越来越多的研究表明，内感受紊乱在包括强迫症和相关疾病在内的各种精神障碍中起着重要作用。然而，抠皮障碍（SPD）的内感觉异常仍未被探索。本研究旨在评估和综合SPD中有关内感受中断的现有证据，采用广泛的内感受定义，包括某些类型的皮肤介导信号。我们检索了5个数据库（PubMed, Scopus， EBSCO, Web of Science, Embase），以查找报告SPD与任何内感受模态/维度之间关联的文章。还进行了引文跟踪。数据库检索确定了118篇文章，并对另外9篇文章进行了引用跟踪。8项不同的研究，涉及1338名参与者（462名SPD患者）符合纳入标准。研究结果表明SPD的情感触摸加工受到干扰。疼痛敏感性并不能区分SPD患者和对照组。有限的证据表明，SPD患者的心脏内感受准确性降低，情绪意识降低，同时对身体信号的高度依赖与对采摘的控制能力下降之间存在联系。事后分析表明，瘙痒过程可能受到干扰。总体而言，初步证据表明SPD存在内感受性中断。

期刊介绍： The official journal of the International Behavioral Neuroscience Society publishes original and significant review articles that explore the intersection between neuroscience and the study of psychological processes and behavior. The journal also welcomes articles that primarily focus on psychological processes and behavior, as long as they have relevance to one or more areas of neuroscience.
