DOI: 10.31744/einstein_journal/2019AO4405
ABSTRACT
Objective
To prepare an instrument to evaluate health literacy with regard to adherence to drug treatment among diabetics, identify the validity of its content, and estimate its reliability.
Methods
Pilot study, with the following stages of instrument construction: literature review, content validation, reliability estimation (internal consistency/Cronbach’s alpha and reproducibility/Kappa).
Results
The validity of content was completed and presented alpha=0.77 and Kappa values ranged from 0.31 to 1.00.
Conclusion
The instrument was approved regarding content validity, presented acceptable internal consistency and reproducibility. However, when applied, measurement errors it can produce must be considered.
