Idiopathic environmental intolerance (IEI) is characterized by non-specific symptoms attributed to exposure to environmental odours or chemicals at levels below those known to induce adverse health effects. A clarification of whether psychological processes involved in sensory perceptions are associated with IEI would add to our understanding of this complex disorder.
To examine if measures of somato-sensory amplification, autonomic perception and absorption are associated with IEI.
The study included individuals with self-reported or physician-diagnosed IEI. Participants (n = 732) completed questionnaires that included items on descriptive variables of IEI, the Somato-Sensory Amplification Scale (SSAS), the Autonomic Perception Questionnaire (APQ), the Tellegen Absorption Scale (TAS) and a Negative Affectivity Scale (NAS).
Multiple, hierarchical linear regression analyses revealed significant positive associations between SSAS, APQ, and IEI, while small and inverse associations were seen between TAS and IEI.
The association with SSAS and APQ suggests that perceptual personality characteristics are important in understanding this disorder.
特发性环境敏感（IEI）的特点是非特异性症状归因于暴露于环境气味或化学物质水平低于已知引起不良健康影响的水平。澄清参与感官知觉的心理过程是否与 IEI 相关，将有助于我们理解这种复杂的疾病。
研究躯体感觉放大、自主知觉和吸收与 IEI 的关系。
该研究纳入了自我报告或医生诊断为 IEI 的个体。参与者（n=732）完成了问卷，包括 IEI 的描述性变量、躯体感觉放大量表（SSAS）、自主知觉问卷（APQ）、特莱根吸收量表（TAS）和负性情感量表（NAS）的项目。
多项分层线性回归分析显示，SSAS、APQ 与 IEI 呈显著正相关，而 TAS 与 IEI 呈负相关。
与 SSAS 和 APQ 的关联表明，感知人格特征对理解这种疾病很重要。
