Abstract
PURPOSE: The goal of this study was to develop a diabetes-specific scale of patient desire to participate in medical decision making (DPMD) and examine its internal consistency reliability, stability, and validity (content, discriminant, convergent, and construct). METHODS: In a cross-sectional study, 65 patients with type 2 diabetes from a teaching hospital's general medical clinic were interviewed at baseline and 2 weeks later to measure their DPMD scores. Data were collected on demographic/clinical features, health value, social support, desire to make a final decision, and value of patient autonomy. RESULTS: Of the 11 DPMD items, 2 distinct factors emerged representing desire for discussion and desire for information. The DPMD scale had high internal consistency reliability, was stable over 2 weeks and demonstrated good content validity. DPMD scale items were more correlated with each other than with health value or social support. Overall, patients who obtained diabetes education reported greater desire to participate in decisions. Younger patients had a greater overall desire for discussion. The DPMD desire for discussion subscale correlated with patients' desire to make the final treatment decision but not with patients' value of autonomy. CONCLUSIONS: The DPMD is a brief, reliable, valid measure for assessing patient desire to participate in diabetes medical decision making.
