Abstract

Objectives: This study was conducted with the aim of determining the validity and reliability of the Persian version of "General Medication Adherence Scale (GMAS)" in chronic patients in Iran.

Methodology: The study was conducted among patients with chronic diseases in five hospitals of Iran. In this study, after cultural validation, using the steps of Content, Response Reaction, and Internal structure evaluations, the research sample was increased to 150 individuals for exploratory factor analysis (EFA) and 313 chronic patients for confirmatory factor analysis (CFA) to confirm the construct validity. Cronbach's alpha coefficient was used to assess internal consistency, and test-retest method was used to evaluate the reliability of the tool.

Findings: The results of EFA and CFA confirmed the tool with three factors and 11 items. The R² index in the above model was estimated at 0.99, indicating that 99% of the variation in medication adherence scores in research units was explained by GMAS with 11 items. The main indices of the model in factor analysis were all above 0.9, indicating a good fit for the model.

Discussion: Overall, the study results showed that the Persian version of GMAS has acceptable and practical characteristics for evaluating medication adherence, and it can be used as a valid tool in various related fields.

慢性病患者的一般药物依从性量表：波斯语翻译和心理测量评估。

目的：本研究旨在确定波斯版“通用药物依从性量表（GMAS）”在伊朗慢性病患者中的有效性和可靠性。方法：该研究在伊朗五家医院的慢性病患者中进行。在本研究中，经过文化验证，使用内容、反应和内部结构评估的步骤，研究样本增加到150人进行探索性因素分析（EFA），313名慢性病患者进行验证性因素分析，以确认结构的有效性。Cronbachα系数用于评估内部一致性，重测方法用于评估工具的可靠性。调查结果：全民教育和CFA的结果用三个因素和11个项目证实了这一工具。上述模型中的R2指数估计为0.99，表明研究单位99%的药物依从性得分变化是由GMAS解释的，共有11个项目。因子分析表明，该模型的主要指标均在0.9以上，与模型拟合较好。讨论：总体而言，研究结果表明，波斯语版GMAS在评估药物依从性方面具有可接受和实用的特点，可作为各种相关领域的有效工具。

期刊介绍： Chronic illnesses are prolonged, do not resolve spontaneously, and are rarely completely cured. The most common are cardiovascular diseases (hypertension, coronary artery disease, stroke and heart failure), the arthritides, asthma and chronic obstructive pulmonary disease, diabetes and epilepsy. There is increasing evidence that mental illnesses such as depression are best understood as chronic health problems. HIV/AIDS has become a chronic condition in those countries where effective medication is available.
