CareDia Book Education for Type 2 Diabetes: A One-Group Pre–Post Study at Pandak II Health Centre

Diabetes mellitus is a degenerative disease and one of the most prevalent chronic conditions in Indonesia. Medication adherence and self-care behaviour play an important role in achieving optimal disease control in patients with type 2 diabetes mellitus. Educational support using structured media such as the CareDia Book may facilitate behavioural improvement. This study aimed to evaluate changes in medication adherence and self-care behaviour following CareDia Book–based education among patients with type 2 diabetes mellitus at the Pandak II Community Health Centre. A quasi-experimental one-group pre–post design was conducted involving 75 Prolanis participants selected using total sampling based on predefined criteria. Demographic characteristics and outcomes, including medication adherence and diabetes-prevention behaviour, were assessed using validated questionnaires before and after the intervention. Most participants were female (81.33%), had basic education (44%), were unemployed (72%), and had a diabetes duration of more than five years (81.33%). Behaviour and adherence scores increased significantly after exposure to the CareDia Book. These improvements were associated with the educational intervention during the study period. In conclusion, CareDia Book–based education was associated with short-term improvements in medication adherence and self-care behaviour among patients with type 2 diabetes mellitus. Longer follow-up studies are needed to assess the durability and clinical impact of these changes.
