Validation of the Misophonia response scale

In a 2021 study, Dibb et al. validated a new assessment of Misophonia. This assessment, the Misophonia Response Scale (MRS), measures the magnitude of emotional and physiological responses to triggers across all sensory modalities (not just auditory), with subscales for emotional responses, physiological responses, and participation in life. They found that the 22-item scale demonstrated excellent internal consistency (α=0.77-0.89), test-retest reliability (ICC=0.90-0.95), and both convergent and discriminant validity, with a stable three-factor structure confirmed through confirmatory factor analysis. The MRS provides a valid and reliable tool for researchers to assess response severity in individuals with self-reported Misophonia, and they suggested that future research should validate the weighted scoring approach, determine the scale's appropriateness for younger populations, and investigate which aspects of Misophonia (frequency, number of triggers, or response magnitude) cause the greatest functional impairment (Dibb et al., 2021).
