Abstract
Background:
This study was designed to assess differences in diabetes knowledge, diabetes self-management, and perceived control among depressed and nondepressed individuals in an indigent population with type 2 diabetes.
Research Design and Methods:
Depressed and nondepressed patients with the clinical diagnosis of type 2 diabetes were recruited from an indigent care clinic. Subjects completed validated surveys to assess diabetes knowledge, diabetes self-management, and perceived control of diabetes. We compared demographic characteristics and diabetes knowledge, diabetes self-management, and perceived control of diabetes by depression status. Statistical analysis was performed with SPSS version 14.0 (SPSS, Inc., Chicago, IL).
Results:
Of the 201 subjects with diagnosed type 2 diabetes enrolled in the study, approximately 20% (n = 40) of the sample was depressed. Subjects with depression were more likely to report self-care control problems (mean = 2.2 ± 1.0 vs. 1.5 ± 0.6, P < 0.001) and less likely to report positive attitude (mean = 2.9 ± 0.7 vs. 3.7 ± 0.5, P < 0.001), self-care ability (mean = 3.2 ± 3.6 vs. 3.7 ± 0.5, P < 0.001), and self-care adherence (mean = 3.3 ± 0.9 vs. 4.1 ± 0.6, P < 0.001). Depressed patients were less likely to report perceived control of diabetes (mean = 47.7 ± 8.5 vs. 57.8 ± 7.4, P < 0.001). There were no significant differences in diabetes knowledge, self-care understanding, and perceived importance of self-care between depressed and nondepressed patients.
Conclusions:
In this indigent population with type 2 diabetes, diabetes knowledge did not differ significantly by depression status, but diabetes self-management practices and perceived control of diabetes differed significantly by depression status. Patients who were depressed had poorer diabetes self-care and felt they had less control over their disease.
