A Longitudinal Follow-Up Study on Predicting Major Depressive Disorder From Rest-Activity Rhythm Profiles

Sponsor: Chinese University of Hong Kong

Summary

This proposed study will be a longitudinal follow-up study of a case-control study of 160 participants (CREC Ref: 2023.234). This study aims to follow up on the trajectory of depression and rest-activity rhythm (RAR) disruptions, as well as examine their association over time. The investigators aim to identify distinctive RAR profiles of MDD using the data from the original project and hypothesize that two or more groups will be identified based on individual RAR variables using cluster analysis. The investigators hypothesize that significant differences in depressive symptom severity, sleep quality, and other outcome measures collected in this follow-up will be found between the clustered groups. Individuals exhibiting the most disrupted RAR profiles are hypothesized to have the greatest deterioration in depression symptom severity and other outcome measures. The investigators also hypothesize that people persisting with MDD will exhibit greater disruptions in RAR compared to those without MDD at the follow-up. Furthermore, the investigators will examine whether individual RAR parameters are longitudinally associated with changes in depression symptom severity and other outcome measures.
