Validation of the Chinese version of Morningness-Eveningness Questionnaire for screening delayed sleep-wake phase disorder with bipolar disorder among Han Chinese population
To explore the validation of the Morningness-Eveningness Questionnaire (MEQ) for screening Delayed Sleep-Wake Phase Disorder (DSWPD) in bipolar disorder patients specifically within the Han Chinese population.
Key Findings:
Internal consistency, split-half, and retest reliabilities of MEQ were 0.758, 0.719, and 0.661, respectively.
Three factors were obtained for the MEQ scale based on Exploratory factor analysis, with a cumulative factor loading of 37.384%.
BD patients with DSWPD had significantly lower MEQ scores compared to those without DSWPD and healthy controls (p<0.001).
The area under the ROC curve was 0.867, with a cut-off score of 43 yielding sensitivity of 0.83 and specificity of 0.75.
Interpretation:
The Chinese version of MEQ is a reliable and valid tool for screening DSWPD in bipolar disorder patients.
Limitations:
The study's sample size may limit generalizability.
Diagnosis was based on clinical interviews rather than objective measures like actigraphy.
Conclusion:
The Chinese version of MEQ is an effective screening tool for DSWPD among bipolar disorder patients in the Han Chinese community.
