Evaluating the Effectiveness of the Personal Diabetes Questionnaire in the Primary Care Setting [Report]
MetadataShow full metadata
Type 2 diabetes mellitus (T2DM) is a chronic illness managed daily by patients themselves. Poorly controlled diabetes is associated with micro- and macrovascular complications leading to increased morbidity. The Personal Diabetes Questionnaire (PDQ) is a reliable and valid tool that has not been tested in primary care and provides a comprehensive evaluation of knowledge, perceived barriers, and motivational aspects in T2DM self-management. The study aims were to evaluate T2DM self-management of patients in primary care as measured by the PDQ and explore the relationships between perceived barriers and readiness to change and patient self-reported glycated hemoglobin values (HbA1c). A cross-sectional, pilot study was conducted in a convenience sample from south central Texas, N=11. The PDQ assesses four behavioral domains by 13 subscales: blood glucose control, diet, medications, and physical activity. The SPSS software was used for statistical analysis and correlation coefficient techniques were applied to determine significant associations between study variables. Overall, subscales demonstrated good internal consistency (Cronbach’s α=0.56-0.82). No statistically significant correlations existed between HbA1c and participant perceived barriers or readiness to change. Participants were reportedly preparing or actively trying to lose weight and perceived few barriers to completing self-care activities. While participants reported well managed diabetes, their self-management was suboptimal regarding diet behaviors, glucose monitoring, and physical activity. Participants reported optimal diabetes medication adherence. The PDQ remains a valuable tool that can be used by primary care providers to facilitate optimal, patient-centered self-management evaluation and education and minimize diabetes complications.
