Abstract

Background: Understanding personal beliefs about medications is an effective approach to improving adherence. A validated tool is essential for identifying these beliefs in routine clinical practice.

Objective: To validate the factor structure and reliability of the Traditional Chinese version of the Beliefs about Medicines Questionnaire-Specific (BMQ-Specific) among individuals with type 2 diabetes (T2D) in Taiwan.

Methods: The original 10-item BMQ-Specific was translated into Traditional Chinese using a forward-backward translation process and reviewed by four experts in pharmacy practice and educational psychology. A cross-sectional study was conducted among adults with T2D who were using diabetes medications. Participants were recruited from five community pharmacies in Taiwan between June 2023 and May 2024. Internal consistency was assessed using McDonald's omega (ω). Construct validity was examined through exploratory factor analysis, and criterion validity was determined by exploring associations between concern beliefs, medication adherence, and glycemic control, as measured by A1C levels.

Results: Two hundred and seventy-three patients participated in the study. Exploratory factor analysis confirmed a two-factor structure consistent with the original English version, comprising the Specific-Necessity and Specific-Concerns subscales. All items loaded onto their respective subscales. The internal consistency reliability of the instrument was acceptable, with McDonald's ω values of 0.785 for both the BMQ-Specific Necessity and BMQ-Specific Concerns subscales. These satisfactory properties were further supported by predictive validity data, which demonstrated the impact of treatment beliefs on adherence levels. The BMQ-Specific Concerns subscale showed a positive correlation with higher barriers to medication-taking (r = 0.270, p < 0.001) and poorer glycemic control (r = 0.130, p = 0.032).

Conclusion: The Traditional Chinese BMQ-Specific is a reliable and valid tool for assessing medication beliefs among patients with T2D in Taiwan. It can be effectively incorporated into clinical practice to support patient-provider communication and improve medication adherence.

台湾地区成人2型糖尿病患者中药信念问卷的验证。
背景:了解个人对药物的信念是提高依从性的有效途径。一个有效的工具对于在常规临床实践中识别这些信念是必不可少的。目的:验证台湾地区2型糖尿病(T2D)患者中药信念量表(BMQ-Specific)的因子结构及信度。方法:采用正反译法将原10项BMQ-Specific量表翻译成中文,并由4位药学实践和教育心理学专家进行评审。一项横断面研究在使用糖尿病药物的成年T2D患者中进行。参与者在2023年6月至2024年5月期间从台湾的五个社区药房招募。内部一致性用麦当劳的ω (ω)来评估。通过探索性因子分析检验结构效度,通过探究关注信念、药物依从性和血糖控制之间的关联来确定标准效度,以A1C水平测量。结果:273例患者参与了研究。探索性因子分析证实了与原英文版本一致的双因子结构,包括特定必要性和特定关注子量表。所有项目都被加载到各自的子量表上。该仪器的内部一致性信度是可接受的,BMQ-Specific Necessity和BMQ-Specific Concerns分量表的McDonald's ω值均为0.785。预测效度数据进一步支持了这些令人满意的特性,证明了治疗信念对依从性水平的影响。BMQ-Specific Concerns子量表与较高的服药障碍(r = 0.270, p < 0.001)和较差的血糖控制(r = 0.130, p = 0.032)呈正相关。结论:中医bmq特异性是评估台湾地区t2dm患者用药信念的一种可靠有效的工具。它可以有效地纳入临床实践,以支持患者与提供者的沟通和提高药物依从性。

期刊介绍: Patient Preference and Adherence is an international, peer reviewed, open access journal that focuses on the growing importance of patient preference and adherence throughout the therapeutic continuum. The journal is characterized by the rapid reporting of reviews, original research, modeling and clinical studies across all therapeutic areas. Patient satisfaction, acceptability, quality of life, compliance, persistence and their role in developing new therapeutic modalities and compounds to optimize clinical outcomes for existing disease states are major areas of interest for the journal. As of 1st April 2019, Patient Preference and Adherence will no longer consider meta-analyses for publication.
