Profiling the Impact of Misophonia Using the ICF Classification System

Abstract

Misophonia is characterised by an abnormal extreme reaction to specific sound stimuli known as triggers. The reactions can be emotional, behavioural or physiological. In response to triggers, a person with misophonia might express irritation, anger or disgust by being verbally or physically aggressive. This ultimately impacts their quality of life. The present study aimed to determine the impact of misophonia on everyday life using the International Classification of Functioning, Disability and Health (ICF) as a classification system. The study sample included 51 individuals with misophonia. The data was collected using two open-ended questions, the Problem Question (PQ) and the Life Effects Question (LEQ). The responses were linked to categories within ICF using a simple content analysis approach. Of 294 responses obtained, 222 were related to PQ, and 72 were associated with LEQ. Activity Limitations and Participation Restrictions were predominant in misophonic individuals, followed by Impairments of Body Function. There is a significant relationship between gender and the ICF domains. The study alludes to the multifaceted characteristics of the effect of misophonia on persons affected. It demonstrates the advantages of using open-ended questions in studying this impact.
