Quality of Life in Chinese Working and School Age Population With MDD

A Survey of Quality of Life in Chinese Working and School Age Population With Major Depressive Disorder

Major depressive disorder (MDD) is a common mental illness with high prevalence and global burden. Previous studies revealed that over 70% patients in remission still had decreased quality of life, severe function impairment, low positive mental health score and poor coping ability. However, few studies focus on working and school age patients with MDD. A GBD survey showed that over 40% MDD patients are 15-50 years old. Therefore, we initiate the present multi-center cross-sectional survey to investigate the associations between clinical symptoms, cognitive function, occupational/study ability, and quality of life in Chinese working and school age population with MDD who are in remission.

This is a multi-center cross-sectional study. Patients with MDD who received medication treatment and achieved remission for at least 8 weeks will be enrolled. For all the participants, demographic information will be collected; clinical symptoms, cognitive function, occupational/study ability, and quality of life will be evaluated by using 17-items HAMD, PHQ-9, HAMA, PSQI, SHAPS, HCL-32, SDS, LEAPS, QOL-6, PFQ and THINC-it toolkit.

• According to assessment, patients should meet the DSM-5 criteria for MDD when in past episodes;
• Patients received stable ant-depression medication treatment for at least 8 weeks before enrolment;
