摘要
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 (χ2 = 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.
