An interventional study of Individualized automatic coaching message for glycemic management and depressive symptom in Diabetes Mellitus Type 2, Continuous Glucose Measurement and Depressive Symptom, sponsored by Samsung Medical Center. Completed at 1 site in South Korea. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-01-02.

This is a 12-week, single-center, randomized, prospective, confirmatory study of effectiveness of the individualized automatic coaching messages for glycemic management based on continuous glucose monitoring and depressive symptom in insulin-treated patients with type 2 diabetes.
This study will enroll patients with type 2 diabetes who are insulin-treated outpatient care at the Department of Endocrinology and Metabolism, Samsung Medical Center. For 12 weeks, both intervention and control groups will apply continuous glucose monitoring system. The intervention group will receive weekly personalized coaching messages for glycemic management based on data from continuous glucose monitoring and bi-weekly personalized coaching messages for depressive symptoms based on depression questionnaires. The control group will not receive the coaching messages. The aim of this study is to evaluate whether the efficacy of individualized automatic target coaching messages based on continuous glucose monitoring metrics and depressive symptom assessments is superior to those who do not receive the messages in insulin-treated patients with type 2 diabetes.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

The study will enroll insulin-treated patients with type 2 diabetes who are already receiving standard care and diabetes management through outpatient visits. For 12 weeks, the intervention group and control will apply continuous glucose monitoring. The intervention group will receive weekly personalized coaching messages for glycemic management based on data from continuous glucose monitoring and bi-weekly personalized coaching messages for depressive symptoms based on depression questionnaires for 12 weeks.
Other: Individualized automatic coaching message for glycemic management and depressive symptom
The control group will continue their existing treatment and wear a continuous glucose monitoring device, responding to both surveys by accessing the survey link sent to their cell phone. This will allow for the assessment of baseline satisfaction (DTSQ) and depressive symptoms (PHQ-9).
For 12 weeks, the intervention group will apply continuous glucose monitoring system and receive weekly personalized coaching messages for glycemic management based on data from continuous glucose monitoring and bi-weekly personalized coaching messages for depression symptoms based on depression questionnaires.

Diabetes treatment satisfaction
Diabetes Treatment Satisfaction Questionnaire (DTSQ); Minimum and Maximum Values: The DTSQ consists of eight items, with six items measuring satisfaction scored on a 0-6 scale (where 0 is very dissatisfied and 6 is very satisfied). The scores for these six items are summed, giving a total score range from 0 to 36. Higher Scores: Higher scores on the DTSQ indicate better satisfaction with diabetes treatment. A higher total score suggests greater satisfaction, while a lower score indicates dissatisfaction.
Time frame: Week 12
Depressive symptoms
Patient Health Questionnaire-9 (PHQ-9); Minimum and Maximum Values: The PHQ-9 consists of nine items, each scored from 0 (not at all) to 3 (nearly every day). The scores for each item are summed to give a total score, resulting in a range from 0 to 27. Higher Scores: Higher scores on the PHQ-9 indicate worse outcomes, meaning greater severity of depressive symptoms. Lower scores suggest fewer symptoms of depression or none at all. Interpretation of Scores: 0-4: Minimal or no depression; 5-9: Mild depression; 10-19: Moderate depression; 20-27: Severe depression
