‘A necessary evil’: associations with taking medication and their relationship with medication adherence

Cognitive factors, like beliefs, have been studied extensively as determinants of medication adherence, while affect associated with taking medicines has been studied much less. In the present study (N = 525), we investigated affect by assessing patients’ first associations with taking their medicines. Results showed that these associations were related to self-reported medication adherence: Patients who associated taking medicines with negative affect were the least adherent, while those associating taking medicines with the need to take medicines were the most adherent. Our results support the idea that affect should be considered an important determinant of adherence.
