Reliability of New Measures of Cost-Related Medication Nonadherence

Abstract

The estimated test-retest reliability of the measures of cost-related medication nonadherence were generally high. The measures have been integrated into the nationally representative Medicare Current Beneficiary Survey (MCBS), an ongoing national panel survey of Medicare beneficiaries, which will allow researchers and policymakers to identify changes in cost-related nonadherence among disabled and elderly Medicare beneficiaries.
