Plain English Summary
Background and study aims
This study focuses on the negative emotions that play an important role in the development of type 2 diabetes mellitus (T2DM) and its complications. Drug therapy, psychological therapy and psychological health education are used in this study to improve the patients blood glucose levels. We are looking for the right scheme for the prevention and management of pre-diabetes and T2DM. We are also looking for some psychological indicators which would be an early warning for T2DM.
Who can participate?
Individuals seeing a doctor in the participating hospitals in China.
What does the study involve?
Participants are randomly assigned to one of five groups: the control group (conventional diabetes education only), the metformin group, the psychological treatment group, the anti-depressant group, or the psychological health education group. Participants receive the respective treatments according to the group to which they belong; all participants also receive conventional diabetes education. All subjects are interviewed and take an oral glucose tolerance test (OGTT) at the beginning of the study and are followed up after 1 and 2 years of the study.
What are the possible benefits and risks of participating?
In addition to helping the participants improve negative emotion and lower their blood glucose, the project helped the hospitals and government provide the right scheme for the prevention and management of pre-diabetes and T2DM. There was no significant risk to participants of the study.

Primary outcome measure
1. Changes of indicators of the oral glucose tolerance test and glycated hemoglobin reflecting the function of glycometabolism
2. Numerous neuroendocrine indicators reflecting the function of the hypothalamic-pituitary-adrenal axis and the hypothalamic-pituitary-thyroid axis
3. Numerous psychological tests reflecting personality, coping style, social support, emotion, life satisfaction and alexithymia
Outcome measures were assessed at baseline (T0) before the intervention, reassessed at 1 year and 2 years after the intervention, and then analyzed the psychological warning indicator of psychosomatic disease and optimization scheme for prevention of psychosomatic disease such as T2DM.
Secondary outcome measures
1. To explore the psychological characteristics of pre-diabetes in Chinese adults, including personality, coping style, social support, emotion, life satisfaction and alexithymia
2. The relationship between those psychological indicators and neuroendocrine indicators or glycometabolism
3. At the end of study, a warning scale for T2DM should be designed and can be applied in practice
