Background Changes in the regulation of interpersonal distance, or “personal space” (PS), have been repeatedly observed in schizophrenia and, in some studies, linked to negative symptoms. However, the neurobiological basis of these impairments is poorly understood. Methods Personal space measurements, functional connectivity of a brain network sensitive to intrusions into PS, and symptoms of social withdrawal and anhedonia were assessed, and associations among these outcomes measured, in 33 individuals with a psychotic disorder (primarily schizophrenia [SCZ]) and 36 control subjects (CON). Results Personal space size was significantly higher (P = .002) and PS permeability (reflecting the capacity to tolerate intrusions into PS) was significantly lower (P = .021) in the SCZ relative to the CON group, and both measures were significantly correlated with social anhedonia and withdrawal in the full sample (all P < .007). Moreover, functional connectivity between the PS and default mode (DM) networks was significantly correlated with the permeability, but not the size, of PS in the full sample and in the SCZ and CON groups separately, and with social withdrawal in the SCZ group. Lastly, the association between PS-DM network connectivity and social withdrawal in the SCZ group was fully mediated by PS permeability. Discussion Neural and behavioral aspects of PS regulation are linked to social motivation in both healthy individuals and those with psychotic disorders, suggesting that measurements of PS could serve as transdiagnostic markers of social functioning.

精神分裂症和健康个体个人空间和社会功能变化的神经相关性

背景 在精神分裂症中反复观察到人际距离或“个人空间”(PS)调节的变化,并且在一些研究中与阴性症状有关。然而,人们对这些损伤的神经生物学基础知之甚少。方法 在 33 名精神病患者(主要是精神分裂症 [SCZ])和 36控制对象(CON)。结果 与 CON 组相比,SCZ 的个人空间大小显着更高(P = .002),PS 渗透性(反映了对 PS 入侵的耐受能力)显着降低(P = .021),在整个样本中,这两项指标都与社交快感缺乏和退缩显着相关(所有 P < .007)。此外,PS 和默认模式 (DM) 网络之间的功能连接性与整个样本以及 SCZ 和 CON 组中 PS 的渗透性而非大小显着相关,并且与 SCZ 组的社会退缩显着相关。最后,SCZ 组 PS-DM 网络连接与社交退缩之间的关联完全由 PS 渗透性介导。讨论 PS 调节的神经和行为方面与健康个体和精神病患者的社会动机有关,这表明 PS 的测量可以作为社会功能的跨诊断标志。此外,PS 和默认模式 (DM) 网络之间的功能连接性与整个样本以及 SCZ 和 CON 组中 PS 的渗透性而非大小显着相关,并且与 SCZ 组的社会退缩显着相关。最后,SCZ 组 PS-DM 网络连接与社交退缩之间的关联完全由 PS 渗透性介导。讨论 PS 调节的神经和行为方面与健康个体和精神病患者的社会动机有关,这表明 PS 的测量可以作为社会功能的跨诊断标志。此外,PS 和默认模式 (DM) 网络之间的功能连接性与整个样本以及 SCZ 和 CON 组中 PS 的渗透性而非大小显着相关,并且与 SCZ 组的社会退缩显着相关。最后,SCZ 组 PS-DM 网络连接与社交退缩之间的关联完全由 PS 渗透性介导。讨论 PS 调节的神经和行为方面与健康个体和精神病患者的社会动机有关,这表明 PS 的测量可以作为社会功能的跨诊断标志。PS 在完整样本和 SCZ 和 CON 组中的比例分别为,并且在 SCZ 组中具有社会退缩。最后,SCZ 组 PS-DM 网络连接与社交退缩之间的关联完全由 PS 渗透性介导。讨论 PS 调节的神经和行为方面与健康个体和精神病患者的社会动机有关,这表明 PS 的测量可以作为社会功能的跨诊断标志。PS 在完整样本和 SCZ 和 CON 组中的比例分别为,并且在 SCZ 组中具有社会退缩。最后,SCZ 组 PS-DM 网络连接与社交退缩之间的关联完全由 PS 渗透性介导。讨论 PS 调节的神经和行为方面与健康个体和精神病患者的社会动机有关,这表明 PS 的测量可以作为社会功能的跨诊断标志。
