Background:

Accurate measurement of patient adherence is crucial for clinical research.
Various adherence assessment methods exist, each with limitations.
Biomarkers and self-report are common adherence measures.

Purpose of the Study:

To review available adherence measures for researchers.
To evaluate the utility and limitations of adherence markers.
To provide guidance on selecting appropriate adherence assessment methodologies.

Main Methods:

Literature review of adherence measurement techniques.
Comparative analysis of different adherence assessment tools.
Discussion of the advantages and disadvantages of each method.

Main Results:

Adherence measures vary in the information they provide and their limitations.
Markers offer insights into recent adherence but lack quantitative data and can be affected by confounding factors.
The research question's nature should inform the choice of adherence definition and assessment method.

Conclusions:

Markers are valuable for validating self-reports and confirming recent medication intake.
No single adherence measure is universally superior; method selection depends on research objectives.
A combination of methods may provide a more comprehensive understanding of adherence over time.
