The purpose of this study was to develop and psychometrically test a new instrument for measuring self-management of adults with type 2 diabetes. Data were collected from 634 diabetic adults recruited from three teaching hospitals in Taiwan. Construct validity was determined by confirmatory factor analysis (CFA). Tests of internal consistency and test–retest were used to assess the reliability of the diabetes self-management instrument (DSMI). Initial results of CFA did not fully support the proposed five-factor model. After the model was modified, the fit indices indicated that this model fits the data best. This model was further cross validated in a second sample. Cronbach's alpha coefficient of the DSMI total scale was .94. The test–retest correlations for the DSMI total scale were acceptable (r = .73, p < .01). © 2008 Wiley Periodicals, Inc. Res Nurs Health 31:370–380, 2008
