Abstract

Purpose: To develop a scale for evaluating the medication use competency of older adults and verify its psychometric properties.

Method: The Medication Use Competency Scale (MUCS) was initially formulated based on a literature review, theoretical frameworks, and qualitative interviews using a hybrid model. The scale was then tested on 245 older adults.

Results: Exploratory factor analysis identified 23 items across five factors: attitude, physical skills, knowledge, effort to sustain, and cognitive skills, explaining a significant portion of the variance. Construct validity was verified, along with criterion validity, which demonstrated a moderate correlation (r = 0.40, p < 0.001) with the eight-item Morisky Medication Adherence Scale. The scale exhibited strong internal consistency, with a Cronbach's alpha of 0.84, and test-retest reliability of 0.73 (p < 0.01).

Conclusion: The MUCS is a reliable and valid tool for assessing medication use competency in the older adult population. [Research in Gerontological Nursing, 18(3), 154-164.].

老年人用药能力量表的编制与验证。

目的：编制老年人用药能力评价量表，并对其心理测量特性进行验证。方法：在文献综述、理论框架和混合模型定性访谈的基础上，初步制定了药物使用能力量表（MUCS）。然后对245名老年人进行了测试。结果：探索性因素分析确定了五个因素中的23个项目：态度，身体技能，知识，维持努力和认知技能，解释了差异的重要部分。结构效度和标准效度均与莫里斯基药物依从性量表有中等相关性（r = 0.40, p < 0.001）。量表具有较强的内部一致性，Cronbach's alpha为0.84，重测信度为0.73 （p < 0.01）。结论：MUCS是一种可靠、有效的评估老年人用药能力的工具。[老年护理研究，xx(x)， xx-xx.]

期刊介绍： Research in Gerontological Nursing is a forum for disseminating peer-reviewed, interdisciplinary, cutting-edge gerontological nursing research and theory to investigators, educators, academicians, clinicians, and policymakers involved with older adults in all health care settings. The Journal accepts manuscripts reporting research, theory, integrative and systematic reviews, instrument development, and research methods with the aims of improving the wellness and quality of care of the older adult population. Theory papers should advance gerontological knowledge, and integrative reviews should provide an analysis of the state of the science and provide direction for future research.
