The Effect of Mobile Application Supported Education and Counselling on Intention, Attitude, Behaviour and Self-Efficacy of Pregnant Women With Gestational Diabetes
The Effect of Mobile Application Supported Education and Counselling on Intention, Attitude, Behaviour and Self-Efficacy of Pregnant Women With Gestational Diabetes
This randomized controlled trial aims to evaluate the impact of mobile application-supported education and counseling on the intention, attitude, behavior, and self-efficacy of pregnant women diagnosed with gestational diabetes. The study will be conducted at Ankara Bilkent City Hospital, with participants assigned to intervention and control groups. The intervention group will receive planned education and counseling via a mobile application, while the control group will receive standard hospital education. Data will be collected at predetermined intervals, and outcomes will be compared between the groups. The study seeks to determine the effectiveness of a mobile application-supported approach in the management of gestational diabetes.
Gestational Diabetes Mellitus (GDM) is a carbohydrate intolerance disorder that develops during pregnancy or is first diagnosed during this period. If not properly managed, it can lead to serious complications for both the mother and the fetus. Current guidelines recommend healthy nutrition, regular physical activity, self-monitoring of blood glucose, and support from healthcare professionals for the management of GDM. In recent years, mobile health applications have emerged as valuable tools for providing pregnant women with rapid access to information, personalized counseling, and behavioural change support. However, studies evaluating the effects of mobile application-supported interventions in pregnant women with GDM who have initiated insulin therapy remain limited.
This randomized controlled trial aims to evaluate the effect of mobile application-supported education and counseling on the intention, attitude, behaviour, and self-efficacy levels of pregnant women with GDM who have initiated insulin therapy. The study will be conducted at the Internal Medicine Outpatient Clinic of the Obstetrics and Gynecology Hospital, Ankara Bilkent City Hospital. Pregnant women meeting the inclusion criteria will be randomly assigned to either the intervention or control group using a simple randomization method. A total of 94 participants (47 in the intervention group and 47 in the control group) will be included in the study.
In the intervention group, the developed mobile application will be installed on participants' smartphones, and a structured two-week education and counseling program will be implemented. The educational content will comprise seven modules: Essential Knowledge on Gestational Diabetes, Blood Glucose Monitoring in Pregnancy, Fundamental Information on Insulin Therapy in Pregnancy, Management of hypoglycemia and Hyperglycemia in Gestational Diabetes, Healthy Nutrition in Gestational Diabetes, Physical Activity and Exercise in Gestational Diabetes, and General Health Recommendations for a Healthy Life in Gestational Diabetes. Each educational module will be supported with audio recordings and followed by a question-and-answer session to enhance motivation. Daily motivational notifications (e.g., exercise reminders, healthy eating recommendations, water intake reminders) will be sent via the application, and participants' blood glucose records and module completion status will be monitored by the researcher through the administrator panel.
The control group will receive standard face-to-face diabetes education, in line with hospital protocols, for two weeks. This education will cover content comparable to that provided to the intervention group. Assessments will be conducted at three stages for both groups:
Throughout the study, all participants will be asked to regularly complete the Self-Monitoring of Blood Glucose (SMBG) log, whereas the intervention group will additionally record their blood glucose measurements via the mobile application. This study aims to generate robust evidence on the effectiveness of mobile health applications in managing GDM and to contribute to the wider adoption of digital health solutions during pregnancy.
