Measuring compliance can be challenging. Common methods include:
1. Self-Reporting: Patients report their adherence, but this method can be subject to recall bias and social desirability bias. 2. Pill Counts: Counting the remaining pills can provide a more objective measure, although it assumes the patient did not lose or discard the medication. 3. Electronic Monitoring: Devices like electronic pill bottles can track when the medication is taken. This method is more accurate but costly.
