Abstract Misophonia is a sound sensitivity disorder characterized by a strong aversion to specific sounds (e.g., chewing). Here we present the Sussex Misophonia Scale for Adults ( SMS-Adult), within an online open-access portal, with automated scoring and results that can be shared ethically with users and professionals. Receiver operator characteristics show our questionnaire to be “excellent” and “good-to-excellent” at classifying misophonia, both when dividing our n = 501 adult participants by recruitment stream (self-declared misophonics vs. general population), and again when dividing them with by a prior measure of misophonia (as misophonics vs. non-misophonics). Factor analyses identified a five-factor structure in our 39 Likert-type items, and these were Feelings/Isolation, Life consequences, Intersocial reactivity, Avoidance/Repulsion, and Pain. Our measure also elicits misophonia triggers, each rated for their commonness in misophonia. We offer our open-access online tool for wider use ( www.misophonia-hub.org ), embedded within a well-stocked library of resources for misophonics, researchers, and clinicians.

Abstract
| Background/Purpose | Background- - Existing measures of misophonia have limitations - Need for a validated, comprehensive measure of misophonia symptoms Purpose- - Develop and validate a new questionnaire (SMS-Adult) to measure misophonia in adults - Determine factor structure of misophonia symptoms - Establish diagnostic threshold for clinically significant misophonia |
| Participants/samples | - 501 adults total (398 female, 82 male, 12 non-binary, 9 unreported) - 143 self-declared misophonics recruited from online communities - 358 from general/student population |
| Measures | - Sussex Misophonia Scale for Adults (SMS-Adult) - Misophonia Questionnaire (MQ; Wu et al., 2014) |
| Procedures | - Participants completed SMS-Adult and MQ online - SMS-Adult Part 1: 48 trigger items across 8 categories - SMS-Adult Part 2: 53 Likert-type items on emotions/behaviors/consequences |
| Results | - EFA revealed 5-factor structure for SMS-Adult Part 2: 1. Feelings/Isolation 2. Life consequences 3. Intersocial reactivity 4. Avoidance/Repulsion 5. Pain - ROC analysis showed "excellent" classification accuracy (AUC = .91) - Optimal diagnostic threshold of 50.5/156 on SMS-Adult Part 2 - 87.5% sensitivity, 86.2% specificity at this threshold - Strong correlations between SMS-Adult and MQ scores |
| Limitations:: | • Self-report data • Possible sampling bias toward more severe cases • Some redundancy in questionnaire items |
| Future Directions:: | • Validate in independent samples • Examine longitudinal consistency • Further explore potential gender differences |
| Relevance:: | • describes the development and validation of a web based misophonia assessment • the measure shows some promise, but has limitations in regards to describing intensity of specific triggers, and could use further validation • the web based tool makes scoring easy and automatic, and they has systems in place to insure confidentiality • could use a deeper review should I decide to use this in a future study |

my questions
my comments
- Author highlights something I hadn’t thought about the fact that a lot of Misophonia triggers are slightly disturbing. Even people without Misophonia so there’s an inherent difficulty in separating the phonic effect from just general aversiveness. (page )

reading notes
- SMS-Adult available online with automated scoring (www.misophonia-hub.org/test)
- Parallel adolescent version available for continuity across age groups
- 99.4% of misophonics had at least one trigger in top 39 ranked triggers
- Pain included as a factor, though its role in misophonia definition remains debated
- Threshold should be interpreted as indicating clinically significant symptoms, while recognizing misophonia exists on a spectrum of severity
