Association between health literacy and HIV treatment adherence: further evidence from objectively measured medication adherence.

Background: People with lower-health literacy are vulnerable to health problems. Studies that have examined the association between literacy and medication adherence have relied on self-reported adherence, which is subject to memory errors, perhaps even more so in people with poor literacy.

Purpose: To examine the association between health literacy and objectively assessed HIV treatment adherence.

Monitoring medication adherence by unannounced pill counts conducted by telephone: reliability and criterion-related validity.

Background: Although demonstrated valid for monitoring medication adherence, unannounced pill counts conducted in patients' homes are costly and logistically challenging. Telephone-based unannounced pill counts offer a promising adaptation that resolves most of the limitations of home-based pill counting.

Purpose: We tested the reliability and criterion-related validity of a telephone-based unannounced pill count assessment of antiretroviral adherence.

Adherence to antiretroviral therapy assessed by unannounced pill counts conducted by telephone.

Background: Unannounced pill counts conducted in patients' homes is a valid objective method for monitoring medication adherence that is unfortunately costly and often impractical. Conducting unannounced pill counts by telephone may be a viable alternative for objectively assessing medication adherence.

Purpose: To test an unannounced pill count assessment of adherence conducted by telephone.
