Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background and objectives:

Recently the news of intern doctors' death due to overloaded work or committing suicide has made the authorities concerned put emphasis on the mental health care of medical staffs and related policies of psychological interventions. The prefrontal lobe plays an important role in the working memory, executive function and problem-solving abilities of the brain. Currently, no neuroimaging studies investigating the impact of job stress on the prefrontal love functions in intern doctors. Functional near-infrared spectroscopy (fNIRS) measures the cortical functions of the frontotemporal regions and has been widely used as a biomarker to aid in differential diagnoses in major psychiatric illnesses in Japan. The present study will investigate impact of the job stress on brain cortical activity during a verbal fluency test (VFT) by using fNIRS.

Materials and methods:

A total of 100 participants will be recruited. Clinical measurements of mood status by Beck's Depression Inventory and Beck's Anxiety Inventory, as well as job stress by Chinese Version of the Job Content Questionnaire and the Chinese version of Copenhagen Burnout Inventory will be arranged. The relationship between clinical measurements and cortical activity during a VFT will be analyzed by Pearson's correlation. Multiple regression analysis will be applied to investigate the independent contributions of mood status and job stress.

Expected results and contributions of the study:

Job stress, depression, and anxiety are significantly negatively correlated with cortical activity of prefrontal regions. The importance of mental health of medical staffs under high job stress should be stressed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A total of 100 intern doctors will be recruited. The data including Chinese version of Copenhagen burnout inventory, BDI, BAI, average working hours per day, and average sleeping times were acquired. They will undergo NIRS investigations to detect frontal activities during performing a verbal fluency test. The correlation between stress parameters and cortical activities were examined.
