Example of a barrier profile. The profile shows eight potential adherence barriers: two emotional barriers (feelings with regard to medication and fear of side effects); one emotional/cognitive barrier (concerns about medication usage); two cognitive barriers (necessity beliefs and attitude with regard to medication); one cognitive/practical barrier (self-efficacy), and two practical barriers (inconvenience and knowledge about medication scheme)
