Medication health literacy measure: development and psychometric properties.

ABSTRACT:

Background and purpose

Low levels of health literacy are prevalent worldwide. This report details development and psychometric properties of a health literacy measure for oral medications based on design of the Newest Vital Sign.

Methods

The measure was completed during the baseline interview. A principal components analysis evaluated dimensionality of the measure. Cronbach's alpha assessed subscale internal consistencies.

Results

Internal consistencies and reliability for the subscales were acceptable for a new instrument (alpha = .661, alpha = .686, alpha = .400). A 3-factor structure explained 65.34% of the total variance. Divergent validity with the Rapid Estimate of Adult Literacy in Medicine (REALM) was established.

Conclusions

Our data indicates that the
