Aim The purpose of this study was to develop the D iabetes S elf‐ M anagement B ehavior for O lder K oreans ( DSMB‐O ). This scale is based on the seven relevant domains that have been identified by the A merican A ssociation of D iabetes E ducators ( AADE ) and is adjusted for sociocultural and age‐related characteristics. Methods Four phases were used to develop of the DSMB‐O as a criterion‐referenced measure. In phases 1 and 2, the DSMB‐O adopted the AADE ’s seven domains and established a self‐report questionnaire using a small number of items that are applicable to older K oreans. In phase 3, the DSMB‐O was formulated with 16 preliminary items, including seven subitems. By assessing the content validity, 14 items (including five subitems) were selected. The final phase involved evaluating the DSMB‐O ’s psychometric properties, including test–retest reliability, content validity, and criterion‐related validity, using data from 150 older K oreans with type 2 diabetes. Results The coefficients of agreement and C ohen's K appa for the test–retest reliability test ranged from 0.32 to 1.0 and −0.07 to 1.0, respectively. For the content validity, the values of both the item‐ and scale‐level content validity indices were 1.0. The scores from the DSMB‐O were positively correlated with the scores from the K orean version of the S ummary of D iabetes S elf‐ C are A ctivities Q uestionnaire. Conclusion The DSMB‐O is short and easy for older K oreans to use, as well as having acceptable levels of reliability and validity. Hence, the DSMB‐O can be a useful tool to evaluate diabetes self‐management behaviors in older K oreans with type 2 diabetes.
