Validation of the Adherence Barriers Questionnaire (ABQ) – An Instrument for Identifying Potential Risk Factors Associated With Medication-Related Non-Adherence

Summary: Medication-related non-adherence is a major challenge in the real-life treatment of patients. To meet this challenge successfully, adherence interventions with a tailored approach towards patient-specific adherence barriers are needed. Therefore, a reliable and practicable questionnaire for identification of those adherence barriers in specific patients is needed. The aim of this investigation is to develop and validate such a questionnaire.
