Purpose: The threefold purpose of this study is to assess diabetes knowledge among Hispanic/Latinos attending a culturally sensitive, empowerment-based, diabetes self-management education program; second, to examine the utility of the Spoken Knowledge in Low Literacy in Diabetes (SKILLD) scale as an assessment tool for this population; and third, to assess the relationship between hemoglobin A1C and knowledge improvement in the intervention group.
Method: A prospective, quasi-experimental, repeated-measure design tested pre- and post-A1C and diabetes knowledge using the SKILLD scale. The sample consisted of 71 in the intervention group and 64 controls.
Results: Most participants were female, marginally acculturated, and, on average, 60 years of age. Both groups were similar in baseline diabetes knowledge score (median 6 out of 10), and higher literacy was significantly related to increased baseline knowledge. The intervention group significantly improved at follow-up compared with the controls: Participants in the intervention with low baseline knowledge scores had a mean follow-up score of 5.6; those with a high baseline score had a mean score of 7.6. The intervention cohort scored significantly better in knowing why to see an eye doctor, what are normal fasting blood glucose and A1C, and understanding long-term diabetes complications. Increased knowledge of a normal fasting blood glucose level had a significant effect on follow-up A1C in the intervention group.
Conclusion: The intervention favorably affects diabetes knowledge, and the SKILLD scale has utility with low-literate Hispanic/Latinos. The significant impact on A1C by diabetes knowledge gain shows that the empowerment-based diabetes self-management education was successful for this ethnic population.
