Preliminary validation of the Norwegian version of the Berlin Misophonia Questionnaire Revised (BMQ-R-NOR).

OBJECTIVE: To perform a psychometric evaluation of a Norwegian version of the Berlin Misophonia Questionnaire Revised (BMQ-R-NOR). DESIGN: Participants completed online versions of the self-report questionnaire BMQ-R-NOR on two occasions and MQ-NOR on one occasion. Convergent validity was assessed through Spearman's correlation between BMQ-R-NOR and MQ-NOR. Internal consistency was evaluated with McDonald's omega and Cronbach's alpha. Test-retest reliability was evaluated using Cohen's weighted kappa and intraclass correlation. STUDY SAMPLE: 82 participants with self-reported misophonia took part in the study at T1, and 53 of these participated at T2. However, only 41 of them were included in the test-retest analyses due to 12 participants being in treatment between T1 and T2. RESULTS: Subscales from the BMQ-R-NOR and MQ-NOR were significantly positively correlated, indicating evidence of convergent validity (rs = 0.22*-0.74**). The BMQ-R-NOR showed overall good internal consistency (omega = 0.72-0.93; alpha = 0.70-0.93) and satisfactory test-retest reliability (ICC = 0.35-0.92). CONCLUSION: The psychometric properties of the BMQ-R-NOR are considered satisfactory. However, it is advised to exercise caution when using it until further comprehensive validation studies are conducted to ensure robustness and reliability in clinical practice.

Preliminary validation of the Norwegian version of misophonia questionnaire (MQ-NOR).

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.
