Method: Factor structure of the BMQ-AET was explored alongside internal consistency, convergent validity and acceptability. Results: The BMQ-AET Specific Scale fitted the original 10 item model. Internal consistency of the BMQ-AET was much improved compared to the original BMQ and convergent validity showed predicted direction of correlation, although correlation with BMQ-AET concerns scale was low. Acceptability was good. Conclusions: The evaluation of the BMQ-AET is encouraging, and could facilitate future research around adherence to AET.enhttp://creativecommons.org/licenses/by-nc-nd/4.0/Beliefs about Medicines QuestionnaireAdherenceAdjuvant Endocrine TherapyEvaluationFactor StructureConvergent ValidityArticle2055-1029Health Psychology Open
