PMS63 Assessment of the Osteoporosis Self-Efficacy Scale in Relation to Osteoprotective Behaviors among Type 2 Diabetics Patients in North Malaysia

Abstract

test the feasibility of using the nominal group technique (NGT) to select attributes for DCEs. METHODS: Patients group discussions (4-8 participants) were conducted in Belgium and the Netherlands to prioritize a list of twelve potentially important attributes for osteoporosis drug therapy that were retrieved from literature review and expert discussions. The NGT consisted of three steps: 1) an individual ranking of the twelve attributes by importance from 1 to 12; 2) a group discussion on each of the attributes including a group review of the aggregate score of the initial rankings; and 3) a second ranking task of the same attributes. The selection of attributes for the DCE was based on groups’ ranking and NGT discussions followed by experts’ discussion. RESULTS: In total, 26 osteoporotic patients participated in five nominal group sessions. Most (80%) patients changed their ranking after the discussion. However, the average initial and final ranking did not markedly differ, with two exceptions. In the final rank, the most important medication attributes were effectiveness, side-effects, frequency and mode of administration. It was also observed that some (15%) patients did not correctly rank from 1 to 12, and the order of attributes did play a role in the ranking. CONCLUSIONS: The nominal group technique is feasible and useful for selecting attributes for DCE, although the ranking task may be cognitively difficult and attributes order should vary over different NGT sessions.
