Abstract

Session presented on Sunday, July 26, 2015:

Purpose: To streamline a clinical tool for use with people with diabetes. This study aims to evaluate the psychometric properties of the Diabetes Self-Management Instrument-short form (DSMI-20).

Methods: The short form Instrument (i.e., DSMI-20) was revised from our previous instrument ( i.e., DSMI-35) through in- depth small group discussions and expert validation, and tested it via pilot tests and item analysis. We verified it by exploratory factor analysis (EFA) and correlation with an empowerment scale. Reliability testing included inteRN consistency and test'retest reliability that were estimated by Cronbach's alpha and Pearson correlation coefficients.

Results: EFA identified four factors with loadings ranging from -0.727 to 0.907: communication with HCPs, self-integration, self-monitoring of blood glucose, and problem solving, which accounted for 57.11% of the total variance. Cronbach's alpha coefficient of the DSMI-20 total scale was 0.925 and of subscales ranged from 0.838 to 0.892. The test/retest correlations for the DSMI-20 total scale were acceptable (r = .790, p = .001). Correlation with the diabetes empowerment scale was r =0.552 (p = .001).

Conclusion: The DSMI-20 is a rapid, viable assessment tool for identifying self-management problems among people with diabetes.
