The Beliefs about Medicines Questionnaire (BMQ) and Adherence Starts with Knowledge (ASK-12) questionnaire were originally developed and validated in Western populations to assess beliefs and barriers to medication adherence. The study aim is to validate the BMQ and ASK-12 questionnaire for use in a Singapore population with early stage breast cancer. English-speaking women on adjuvant endocrine therapy (n = 157) were recruited. The BMQ-Specific showed good internal consistency with structural validity. The internal consistency of BMQ-General and ASK-12 Behaviour scale improved with the new factor structure obtained from exploratory factor analysis. Further studies are needed to confirm these factor structures.

药物信念问卷 (BMQ) 和依从性从知识开始 (ASK-12) 问卷最初是在西方人群中开发和验证的，以评估药物依从性的信念和障碍。该研究旨在验证 BMQ 和 ASK-12 问卷在新加坡早期乳腺癌人群中的应用。招募了接受辅助内分泌治疗的说英语的女性 ( n  = 157)。BMQ-Specific 与结构有效性表现出良好的内部一致性。BMQ-General和ASK-12行为量表的内部一致性随着探索性因子分析获得的新因子结构而提高。需要进一步的研究来证实这些因素结构。
