This includes factors such as getting prescriptions filled, memorizing to take medication on time, and understanding the directions.
Common factors to medication adherence include

Disbelief that the treatment is necessary or helping
Difficulty keeping up with multiple medications and complex dosing schedules
Confusion about how and when to take the medication
