Anxiety and depression among Canadian undergraduates with decreased sound tolerance.

Decreased sound tolerance symptoms showed strong, positive correlations with anxiety and depression in Canadian undergraduates.

• Sample consisted of 2095 Canadian undergraduate students
• Both DST subtypes (misophonia and hyperacusis) were assessed alongside mental health measures
• Psychometrically validated measures were used for assessment
• The study used DST and mental health questionnaires administered together

Misophonia, defined as sensitivity to specific trigger sounds cueing aversive responses, was assessed using measures aligned with the recent misophonia consensus definition.

• Prior research had not used psychometrically validated measures aligned with the recent misophonia consensus definition to assess misophonia-mental health relationships
• Misophonia is characterized by aversive responses to specific trigger sounds
• This represents a methodological advancement over previous misophonia-mental health research

There was a complete absence of prior research on the relationship between decreased sound tolerance and mental health in Canadian university populations.

• The authors describe 'a complete dearth of DST-mental health research in Canadian universities'
• The study was conducted specifically to address this gap in the literature
• The setting was Canadian post-secondary institutions

The findings highlight the detrimental effects of decreased sound tolerance and indicate a need for strategies for managing and treating DST in post-secondary institutions.

• DST encompasses both misophonia (sensitivity to specific trigger sounds) and hyperacusis (irritation by general sounds not bothersome to others)
• The authors call for future research on management and treatment strategies specific to post-secondary settings
• Results underscore the mental health burden associated with DST conditions in undergraduate populations
