In a 2020 study, Jager et al. examined the psychiatric, somatic, and psychological nature of misophonia in a large outpatient sample (N = 575) who met the authors’ operational definition using the A-MISO-S, reporting 26% comorbidity with obsessive-compulsive personality traits, 10% with mood disorders, 5% with ADHD, and 3% with autism, along with high levels of perfectionism and neuroticism and significantly impaired quality of life associated with symptom severity. Based on structured psychiatric, medical, and audiological assessment, they found little evidence for a primary audiological basis and identified oral or nasal sounds as required triggers, with hyperfocus emerging as a core feature. The authors concluded that misophonia is a distinct psychiatric disorder requiring systematic psychiatric evaluation due to risk of misdiagnosis and proposed revised Amsterdam UMC 2020 diagnostic criteria.

Impaired Quality of Life Associated with Misophonia Severity

In a 2020 outpatient study of individuals meeting an operational definition of misophonia (N = 575), greater misophonia symptom severity was associated with significantly impaired quality of life. These findings indicate that misophonia symptoms are linked to meaningful functional impairment in daily life and support the characterization of misophonia as a clinically impactful condition. (Jager et al., 2021)

Hyperfocus Emerging as a Core Feature of Misophonia

In a large outpatient study of individuals with misophonia, Jager et al. identified hyperfocus on trigger sounds as a prominent feature of the condition. Participants frequently reported an intense and persistent attentional fixation on trigger stimuli once they were detected, suggesting that hyperfocus may play an important role in the subjective experience and escalation of misophonic responses. (Jager et al., 2021)

Elevated Neuroticism and Perfectionism in Misophonia

A 2020 clinical study examining the psychological characteristics of individuals with misophonia found elevated levels of neuroticism and perfectionism within the sample. These findings suggest that personality traits related to heightened emotional reactivity and rigid performance standards may be associated with the psychological profile of misophonia. (Jager et al., 2021)

Prevalence of Obsessive–Compulsive Personality Traits in Misophonia

In a 2020 outpatient sample of individuals with misophonia, 26% of participants met criteria for obsessive–compulsive personality traits. Additional comorbidities included mood disorders (10%), ADHD (5%), and autism (3%), indicating that obsessive–compulsive personality features are among the more commonly observed psychiatric traits in this population. (Jager et al., 2021)

Hyperfocus on Trigger Sounds

A clinical investigation of misophonia reported that individuals often exhibit hyperfocused attention toward trigger sounds, characterized by difficulty disengaging from the stimulus once it is detected. This attentional fixation may contribute to the escalation and persistence of misophonic reactions during trigger exposure. (Jager et al., 2021)
