Methods: The survey was applied in 100 patients type 1-2 diabetes, 12-70 years-old, both genders. The data was showed descriptively and statistically processed as the internal consistency (Cronbach's alpha) and the factor structure. Results: The analysis of the principal components indicate a structure who comprised 4 factors that explained 32.9% of the total variance. The Cronbach's alpha was 0.8, representing an excellent reliability. Conclusion: The Spanish version of the diabetes knowledge survey has proven to be reliable and valid for application in subsequent research in the Venezuelan population.
