RESUMO
OBJECTIVE: To perform a psychometric validation of a Norwegian version of the Misophonia Questionnaire (MQ-NOR) and to test the link between the personality trait neuroticism and misophonia assessed with the MQ-NOR. DESIGN: Participants completed online versions of the MQ-NOR on two occasions about two weeks apart and the neuroticism scale from BFI-20. STUDY SAMPLE: Two-hundred and twenty-seven (T1) and 173 (T2) participants with self-reported misophonia. RESULTS: The MQ-NOR was found to comprise two factors: Symptom Scale and Emotions and Behaviours Scale. Overall, the MQ-NOR evidenced good internal consistency and test-retest reliability. Regression analyses supported a positive relationship between misophonia and neuroticism that was moderated by participant age, but not gender. CONCLUSION: The MQ-NOR demonstrates good psychometric properties, but until more extensively validated, it is cautiously recommended for use by clinicians in Norway to assessing misophonia. Future validation studies should be carried out.
