Abstract

Introduction Type 2 Diabetes mellitus (DM2) is a chronic condition demanding continuous healthcare. Effective management involves patient engagement, emphasizing person-centered care and shared decision-making (SDM). This study aims to assess SDM and explore its relationship with diabetes control, health behaviors, and distress.

Methods In this prospective study adults with DM2 were followed. Patient involvement was assessed at baseline using the 5-Item Observing Patient Involvement in Decision Making Scale (OPTION-5) for external perspective and the 9-Item Shared Decision-Making Questionnaire (SDM-Q-9) for the patient‘s perspective. Participants completed health measures at baseline and after 6 months, including HbA1c, the Mediterranean Diet Adherence Screener, the International Physical Activity Questionnaire, the Simplified Medication Adherence Questionnaire, and the Diabetes Distress Scale. Multiple linear regression analyzed the relationship between SDM and health outcomes, considering sociodemographic, clinical, and preference variables as covariates.

Results A total of 105 participants (mean age 65 years, 60% females) were included. At baseline, participants perceived moderate levels of shared SDM based on the SDM-Q-9 (66.46±19.35). Conversely, external observers appraised comparatively lower levels (6.11±5.17). At 6-month follow-up, a significant negative association between SDM-Q-9 score and poor medication adherence was found (OR=0.97, p=0.045). Additionally, baseline OPTION-5 score showed a significant negative association with diabetes-related distress (B=-0.86, p<0.001). No significant association was found with glycated hemoglobin, diet adherence or physical activity.

Discussion Consistent with prior research, our study reveals a discrepancy in SDM perceptions between patients and external observers and how these perspectives relate to health-related outcomes.

Conclusions This study underscores the need for comprehensive assessments considering both perspectives to better understand and optimize the impact of SDM on diabetes management and well-being.
