Most current Misophonia scales are not validated, do not include both emotional and physiological responses to triggers, and/or focus only on auditory triggers. This research aimed to develop and validate a measure of the magnitude of the Misophonic response that addressed these omissions.
Three studies were carried out with individuals with self-diagnosed Misophonia. In study 1, expert opinion and participants commented on initial items to determine both face and content validity. In study 2, scale structure, reliability, and convergent and discriminant validity were determined using correlations, principal component analysis (PCA), and reliability analysis. In study 3, factor structure was confirmed in another sample of participants using confirmatory factor analysis (CFA).
The final 22-item scale assesses the magnitude of responses to triggers across any sensory modality. There are three subscales (emotional, physiological, and participation in life), with three additional items measuring frequency of triggers, avoidance of triggers, and time taken to recover from the triggers. The final scale showed suitable discriminant and convergent validity, with good internal consistency (Cronbach's alphas range 0.77 to 0.89). The three-component solution extracted using PCA explained 53.97% of variance, with all items loading between 0.45 and 0.84. The structure was confirmed with CFA (χ = 269.01, p < .001; CFI = 0.96; TLI = 0.96 and RMSEA = 0.045 (CI 0.037-0.053).
The Misophonia Response Scale, which is valid and reliable, will facilitate understanding of Misophonia as it is short and easy to use for self-report in research.
大多数现有的厌恶症量表未经验证，既不包括对触发因素的情绪和生理反应，也不包括仅关注听觉触发因素。本研究旨在开发和验证一种测量厌恶症反应程度的方法，以弥补这些遗漏。
对三名自诊断为厌恶症的个体进行了三项研究。在研究 1 中，专家意见和参与者对初始项目进行了评论，以确定其表面效度和内容效度。在研究 2 中，使用相关分析、主成分分析（PCA）和可靠性分析确定了量表的结构、可靠性以及聚合和区分效度。在研究 3 中，使用验证性因子分析（CFA）在另一组参与者样本中确认了因子结构。
最终的 22 项量表评估了对任何感觉模式触发因素的反应程度。该量表有三个分量表（情绪、生理和参与生活），还有三个额外的项目，用于测量触发因素的频率、对触发因素的回避以及从触发因素中恢复所需的时间。最终的量表显示出适当的区分和聚合效度，具有良好的内部一致性（Cronbach 的阿尔法值范围为 0.77 至 0.89）。使用 PCA 提取的三成分解决方案解释了 53.97%的方差，所有项目的负荷值在 0.45 至 0.84 之间。使用 CFA 验证了该结构（χ=269.01，p<.001；CFI=0.96；TLI=0.96 和 RMSEA=0.045（CI 0.037-0.053）。
该厌恶症反应量表具有有效性和可靠性，它简短易用，可用于研究中的自我报告，这将有助于对厌恶症的理解。
