This study used a battery of tests to assess predictors of non-adherence as well as evaluate the participant's perceptions of their own adherence. More than 90% of the participants judged their adherence to be good, yet less than half reported full adherence to the prescribed regimens. In this study recreational drug use was the factor most associated with missed doses. So what did we learn here? I learned that patients seem to overestimate their adherence to their own medications. Recreational drug use indeed has an effect on adherence (this seems a no-brainer, but has been hotly debated for years).
