This study aimed to conduct a psychometric evaluation of the Adherence to Refills and Medications Scale (ARMS) among patients with HIV/AIDS in Indonesia.
Psychometric analysis was conducted at 2 hospitals and 7 public health centers at the voluntary counseling and testing clinic. Content validity was measured by assessing the relevance and clarity of each ARMS item. Construct validity was also assessed. Reliability was evaluated using internal consistency and test-retest reliability.
This study involved 11 experts in the assessment of the content validity and 240 participants in the estimation of the construct validity. All ARMS items were generally considered easy to understand and relevant, with scale-level content validity index based on the average method (S-CVI/Ave) of 0.9 (>0.78) and item-level content validity index (I-CVI) in the range from 0.5 to 1 for the relevance level and S-CVI/Ave of 0.95 (>0.78) and I-CVI in the range from 0.8 to 1 for the clarity level. Two items (numbers 2 and 3) were revised based on experts' suggestions to enhance comprehension. Confirmatory factor analysis supported 2 subscales: adherence to taking medications and adherence to refilling prescriptions. Good reliability was supported by internal consistency (Cronbach's α 0.793) and test-retest reliability (intraclass correlation coefficient 0.722) for the overall adherence score.
The Indonesian version of ARMS is a valid and reliable medication adherence scale when used in Indonesian patients with HIV/AIDS.
本研究旨在对印度尼西亚 HIV/AIDS 患者的《 refill 和药物依从性量表》（ARMS）进行心理计量学评估。
在 2 家医院和 7 家公共卫生中心的自愿咨询和检测诊所进行心理计量学分析。内容效度通过评估每个 ARMS 项目的相关性和清晰度来衡量。还评估了结构效度。使用内部一致性和重测信度评估可靠性。
本研究涉及 11 名评估内容效度的专家和 240 名评估结构效度的参与者。所有 ARMS 项目通常被认为易于理解且相关，基于平均法（S-CVI/Ave）的量表水平内容效度指数（S-CVI/Ave）为 0.9（>0.78），项目水平内容效度指数（I-CVI）为 0.5-1 为相关性水平，S-CVI/Ave 为 0.95（>0.78），I-CVI 为 0.8-1 为清晰度水平。根据专家的建议，对两个项目（第 2 项和第 3 项）进行了修订，以提高理解度。验证性因子分析支持 2 个子量表：服用药物的依从性和补充处方的依从性。内部一致性（Cronbach's α 0.793）和重测信度（组内相关系数 0.722）支持总体依从性评分的良好可靠性。
在印度尼西亚 HIV/AIDS 患者中，ARMS 的印度尼西亚版本是一种有效且可靠的药物依从性量表。
