ABSTRACT

<p><b>OBJECTIVE</b>To develop a brief version scale with good validity and reliability to evaluate self-management knowledge, attitude and behavior (KAB) of diabetes patients in a shorter time.</p><p><b>METHODS</b>20 authority experts who specialized in the field of diabetes clinical and non-communicable disease self-management, and familiar with the relevant content of diabetes self-management were selected. Face to face and Email consultation methods were applied in two rounds delphi expert consultations to choose items from the Diabetes Self-management Knowledge, Attitude, and Behavior Assessment Scale (DSKAB, total scale, 98 items). In the first round of expert consultation, experts were asked to select the core items from every dimension and score the extent of familiarity and basis of judgment. In the second round of expert consultation, the significance of the core items which were selected by experts in first round, were graded. The items which entered into the brief scale were determined by harmonious condition of expert opinions.</p><p><b>RESULTS</b>Two rounds of consultation reclaimed 16 and 15 responses respectively, Positive coefficients of experts were 80% and 94% respectively, and both authoritative coefficients were 0.90. In the first round of consultation, experts selected 44.3 ± 6.2 items on average, 42 items were selected according to the integrity of the scale for measuring dimension and content at last. In the second round of consultation, experts thought that the 42 items could measure the important contents of each dimension comprehensive and representative, the item importance scores of knowledge, attitude, and behavior subscale were 8.42 ± 1.17, 8.61 ± 1.24, 8.61 ± 1.02 respectively, and the coordination coefficients of the three subscale were 0.36, 0.20, 0.49 (χ(2) were 89.74, 11.13, 96.03, P<0.05). The total coordination coefficient was 0.38 (χ(2) =199.36, P<0.001), which indicated the concentration of experts(')opinion was acceptable, showed the brief scale with good face validity and content validity.</p><p><b>CONCLUSION</b>The brief scale could evaluate Diabetes Self-management KAB Scale rapidly and relatively comprehensive in groups or individuals diabetes with good face validity and content validity.</p>
