摘要

目的 成见会造成社会分裂,阻碍社会凝聚力与合作。值得注意的是,它对公共卫生有重大影响,尤其是在 COVID-19 等传染病爆发期间。为了填补这一空白,我们对 70 名男性进行了一项双盲、安慰剂对照、受试者内设计的研究,以探讨鼻内注射催产素(OT)对疾病相关成见(即 COVID-19 成见)的显性和隐性处理的影响。结果表明,催产素扩大了高社会焦虑和低社会焦虑参与者在显性 COVID-19 成见上的差异,他们更倾向于将鄙视目标(即 COVID-19 相关群体)的鄙视地位归因于鄙视目标、COVID-19相关群体)归因于个人原因,但与安慰剂治疗相比,低社交焦虑者在催产素治疗下对鄙视目标的责备减少了。此外,催产素还加强了责任归因与其他过程(即情绪、接近动机、社会偏差)之间的联系。总之,这些研究结果表明,鼻内注射催产素可对疾病相关成见的显性认知判断产生时间性影响,但不会对隐性成见产生影响;此外,催产素对不同社交焦虑水平的个体有不同的调节作用。这些发现凸显了催产素对疾病相关鄙视的特质依赖性调节,意味着催产素部分参与了疾病相关鄙视的内分泌系统。通过揭示成见的分子基础及其与社交焦虑等个体特质的关联,我们可以在未来定制干预措施,以满足不同个体的特定需求。

Oxytocin modulation of explicit pandemic stigma in men with varying social anxiety levels

Objective

Stigma can create divisions within societies, hindering social cohesion and cooperation. Notably, it has significant public health implications, especially during infectious disease outbreaks like COVID-19. However, little is known about the neural and molecular basis of disease-related stigma and their association with individual differences.

Methods

To address this gap, we performed a double-blind, placebo-controlled, within-subject design study with 70 males, to investigate the effect of intranasal oxytocin (OT) administration on the explicit and implicit processing of disease-related stigma (i.e., COVID-19 stigma). After self-administrated 24 IU of OT or placebo, participants completed a stigma evaluation task and an Implicit Association Test (IAT) to assess the explicit and implicit processes of stigma evaluation, respectively.

Results

The results showed that oxytocin amplified the differences between participants with high and low social anxiety in explicit COVID-19 stigma, with a higher inclination to attribute the stigmatized status of the stigmatized targets (i.e., COVID-19 related group) to personal causes in high social anxiety individuals, but reduced blame towards the stigmatized targets in low social anxiety individuals under oxytocin compared to placebo treatment. Furthermore, oxytocin strengthened the connections between responsibility attribution and the other processes (i.e., emotional, approach motivation, social deviance). While no modulation of oxytocin on implicit stigma emerged, oxytocin did modulate the associations between specific dimensions of explicit stigma (i.e., social deviance and approach motivation) and implicit stigma.

Conclusion

In conclusion, these findings demonstrated that intranasal oxytocin administration could temporally impact the explicit cognitive judgment in disease-related stigma but not the implicit aspect; furthermore, it modulated in distinct ways in individuals with different levels of social anxiety. These findings highlight the trait-dependent oxytocin modulation on disease-related stigma, implying that oxytocin is partly involved in the endocrine system of disease-related stigma. By unraveling the molecular basis of stigma and its association with individual traits, such as social anxiety, we can tailor interventions to meet specific needs of different individuals in the future.

期刊介绍: Neuropharmacology publishes high quality, original research and review articles within the discipline of neuroscience, especially articles with a neuropharmacological component. However, papers within any area of neuroscience will be considered. The journal does not usually accept clinical research, although preclinical neuropharmacological studies in humans may be considered. The journal only considers submissions in which the chemical structures and compositions of experimental agents are readily available in the literature or disclosed by the authors in the submitted manuscript. Only in exceptional circumstances will natural products be considered, and then only if the preparation is well defined by scientific means. Neuropharmacology publishes articles of any length (original research and reviews).
