Detailed Description
Adopting a healthier lifestyle and disease self-management skills is critical to reducing the risk of diabetes-related complications. Internationally, and in Singapore, the majority of people with diabetes report not having received structured diabetes education, while others have the knowledge and fail to apply it in their daily lives.
Key self-management behaviours recommended by the American Association of Diabetes Educators include physical activity, healthy diet, blood glucose monitoring, and medication adherence, but equally important is healthy coping to maintain a positive attitude toward diabetes management. Life-long patient education and continuous empowerment are paramount to successful self-management in people with diabetes, as recommended by evidence-based diabetes management guidelines.
In addition to patients, their informal carers often play an important role in the management of diabetes. As such, diabetes education for informal carers is essential to achieve the best possible diabetes outcomes in the patient.
There are hundreds of diabetes apps available for the public to download and use, but few are rigorously evaluated for clinically meaningful outcomes. We designed GLOW, a diabetes companion app with a conversational agent, to support people with diabetes and their carers with self-management and knowledge.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Intervention Participants in the intervention group will use GLOW the conversational agent/app for 6 months in addition to their usual diabetes care offered by their attending doctor or endocrinologist. |
Other: GLOW
GLOW is an app for type 2 diabetes support and education that uses a conversational agent to help users develop self-management skills and learn about diabetes and healthy behaviours. This is achieved through a range of interactive strategies.
Other Names:
|
| No Intervention: Control The control group will continue with their usual care, i.e., scheduled consultations with their diabetes team at TTSH and any consultations with healthcare professionals and diabetes education support received either during the consultations or during dedicated times if there are any. They will not be asked to use GLOW during the trial. |
Outcome Measures
Primary Outcome Measures
- Changes in diabetes knowledge among patients and carers using Diabetes Knowledge Questionnaire at baseline, interim (3 months) and end-of-trial (6 months). [baseline, interim (3 months), end-of-trial (6 months)]
The changes in diabetes knowledge will be measured using the scores of a validated questionnaire, Diabetes Knowledge Questionnaire (DKQ).

The changes in diabetes knowledge among patients and carers in the intervention group will be measured using the scores of a new quiz developed based on GLOW modules, GLOW Quiz.
Secondary Outcome Measures

HbA1c values will be retrieved from patient's clinic records and recorded in percentage.
- Changes in fasting blood glucose levels among patients at baseline, interim (3 months) and end-of-trial (6 months). [baseline, interim (3 months), end-of-trial (6 months)]
Fasting blood glucose levels will be retrieved from patient's clinic records and recorded in mmol/L.
- Changes in systolic and diastolic blood pressure among patients at baseline, interim (3 months), end-of-trial (6 months). [baseline, interim (3 months), end-of-trial (6 months)]
Systolic and diastolic blood pressure will be retrieved from patient's clinic records and recorded in mmHg.
- Changes in serum high density lipoprotein (HDL) levels among patients at baseline, interim (3 months), end-of-trial (6 months). [baseline, interim (3 months), end-of-trial (6 months)]
