For older adults, the capacity to self-manage medications may be limited by several factors. However, currently available tools do not permit a comprehensive assessment of such limitations. The Domain Specific Limitation in Medication Management Capacity (DSL-MMC) was developed to address this need. This study aimed to establish the face and content validity of the DSL-MMC.
The DSL-MMC tool consisted of 4 domains and 12 sub-domains with 42 items including: 1. physical abilities (vision, dexterity, hearing); 2. cognition (comprehension, memory, executive functioning); 3. medication regimen complexity (dosing regimen, non-oral administration, polypharmacy); and 4. access/caregiver (prescription refill, new prescription, caregiver). Pharmacists assessed each item for relevance, importance, readability, understandability, and representation. Items with content validity index (CVI) scores of <0.80 for relevance were examined for revision or removal.
Twelve pharmacists participated in the study. CVI scores for relevance and importance of domains were 1.0; of the sub-domains, two were below 0.80. Among the 42 items, 35 (83%) and 30 (71%) maintained CVI scores above 0.80 for relevance and importance, respectively. Five items were removed, three were merged and seven were modified due to low CVI scores and/or feedback.
The DSL-MMC has been validated for content.
对于老年人而言，自我管理药物的能力可能受到多种因素的限制。然而，目前可用的工具无法全面评估此类限制。为满足这一需求，开发了药物管理能力领域特定限制量表（DSL-MMC）。本研究旨在确立DSL-MMC的表面效度和内容效度。
DSL-MMC工具由4个领域和12个子领域组成，包含42个条目，具体如下：1.身体能力（视力、灵活性、听力）；2.认知能力（理解、记忆、执行功能）；3.药物治疗方案复杂性（给药方案、非口服给药、多种药物联合使用）；4.获取/照顾者（处方 refill，新处方，照顾者）。药剂师对每个条目在相关性、重要性、可读性、易懂性和代表性方面进行评估。相关性内容效度指数（CVI）得分<0.80的条目需进行修订或删除。
12名药剂师参与了本研究。各领域相关性和重要性的CVI得分均为1.0；在子领域中，有两个低于0.80。在42个条目中，分别有35个（83%）和30个（71%）的相关性和重要性CVI得分保持在0.80以上。由于CVI得分较低和/或反馈，删除了5个条目，合并了3个条目，并修改了7个条目。
DSL-MMC已在内容方面得到验证。
