This study analysed whether beliefs about medicines mediated the relationship between illness representations and medication adherence.
Adherence to medication is required in diabetes treatment, contributing to decreased blood glycaemic levels. The knowledge and perception of patients about diabetes as well as the beliefs about medicines are considered to be key factors for medication adherence.
The study used a cross-sectional design that included 387 patients recently diagnosed with type 2 diabetes.
Participants were assessed, between 2010 and 2013, and answered the Medication Adherence Scale, the Beliefs about Medicines Questionnaire, and the Brief Illness Perception Questionnaire.
The results of the path analysis showed that beliefs about medicines had a mediating role on self-report medication adherence with the exception of beliefs about specific concerns with medicines. Therefore, both general beliefs and specific needs about medicines mediated the relationship between diabetes consequences and self-report medication adherence as well as between treatment control and self-report medication adherence. Needs about medicines mediated the relationship between personal control and self-report medication adherence.
Health professionals should target beliefs about medicines besides illness representations regarding medication adherence. The current study may help optimize adherence to medication in early-diagnosed type 2 diabetes patients.
本研究分析了药物信念是否介导了疾病表征与药物依从性之间的关系。
糖尿病治疗需要坚持用药，这有助于降低血糖水平。患者对糖尿病的认知和看法以及对药物的信念被认为是药物依从性的关键因素。
该研究采用横断面设计，纳入了387名新诊断的2型糖尿病患者。
在2010年至2013年期间对参与者进行评估，并让他们回答药物依从性量表、药物信念问卷和简短疾病认知问卷。
路径分析结果表明，除了对药物特定问题的信念外，药物信念在自我报告的药物依从性方面具有中介作用。因此，关于药物的一般信念和特定需求介导了糖尿病后果与自我报告的药物依从性之间以及治疗控制与自我报告的药物依从性之间的关系。药物需求介导了个人控制与自我报告的药物依从性之间的关系。
除了疾病表征外，健康专业人员还应关注药物信念以提高药物依从性。本研究可能有助于优化早期诊断的2型糖尿病患者的药物依从性。
