目的 探讨孤独症谱系障碍（autism spectrum disorder, ASD）儿童及亚临床孤独症特质群体感觉过度敏感的具体表现。 方法 于2021年9月—2023年4月，以青少年/成人感觉处理能力剖析问卷、孤独症谱系量表筛选高孤独症特质且感觉过度敏感的18例大学生参与访谈（设为亚临床群体）；以强度抽样抽取11例6~13岁ASD儿童（设为临床群体），对其父母进行深度访谈。使用内容分析和主题分析对访谈文本进行质性整理，以探究两类群体感觉过度敏感的场景、影响、应对方式。 结果 孤独症谱系量表得分与感觉过度敏感呈正相关（r=0.504，P<0.001，n=225）。诱发亚临床和临床人群敏感反应的感官通道相似，均以听觉敏感最为突出。感觉过度敏感给情绪、生理、认知、人际关系及适应功能带来负面影响，各方面彼此交织，形成整体性的体验。回避是两类人群最常用的应对策略（亚临床群体16人44次，临床群体8人40次）。临床群体需要寻求外界帮助（18次），而亚临床群体采取更主动的策略（即直面、转移注意力）缓解不良影响（51次）。 结论 感觉过度敏感是整个ASD儿童的常见表现，带来广泛的负面影响，亟需社会层面的包容接纳及有效干预手段的开发。

Objective To explore the manifestations of sensory hypersensitivity in children with autism spectrum disorder (ASD) and individuals with subclinical autistic traits. Methods From September 2021 to April 2023, interviews were conducted on 18 college students with high levels of autistic traits and sensory hypersensitivity selected using the Adolescent/Adult Sensory Profile and the Autism Spectrum Quotient (as subclinical group). Interviews were also conducted on the parents of 11 children with ASD aged 6-13 years selected using the intensity sampling method (as clinical group). Qualitative content analysis and thematic analysis were performed on the interview texts to investigate the scenarios and impact of sensory hypersensitivity and coping strategies in the two groups. Results The Autism Spectrum Quotient score was significantly positively correlated with sensory hypersensitivity (r=0.504, P<0.001; n=225). Sensory modalities that triggered sensitive reactions were similar in the subclinical and clinical groups, with auditory hypersensitivity being the most prominent. Sensory hypersensitivity had significant negative impact on emotional wellbeing, cognitive ability, physical health, interpersonal relationships, and general adaptive functioning. These dimensions were interconnected, culminating in a holistic experience. Avoidance was the most commonly used coping mechanism for both groups (16 subclinical participants mentioned it 44 times; 8 clinical participants mentioned it 40 times). The clinical group required more support and help from their caregivers (18 times), while the subclinical group used more proactive coping strategies (e.g., facing sensitive scenarios, distracting attention) to alleviate the negative impact (51 times). Conclusions Sensory hypersensitivity is a common manifestation across the broad ASD phenotype, posing negative effects on multiple aspects of their lives. There is an urgent need for social tolerance and acceptance as well as the development of effective intervention measures.
