To develop and test the content validity of the Self-Care of Oral Anticancer Agents Index (SCOAAI).
SCOAAI items were developed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. The Middle Range Theory of Self-Care of Chronic Illnesses informed item generation. A four-phase procedure was followed; Phase 1: items were created based on a previous systematic review and a qualitative study; Phase 2: the SCOAAI comprehensibility and comprehensiveness were established through qualitative interviews with clinical experts and with patients (Phase 3); and Phase 4: the SCOAAI was then administered through an online survey to a group of clinical experts for the Content Validity Index (CVI) calculation.
The first version of the SCOAAI included 27 items. Five clinical experts and 10 patients tested the comprehensiveness and comprehensibility of instructions, items, and response options. Fifty-three experts (71.7% female, mean experience with patients on oral anticancer agents 5.8 years [standard deviation ± .2]; 66% nurses) participated in the online survey for content validity testing. The final version of the SCOAAI includes 32 items. Item CVI ranges between 0.79 and 1; the average Scale CVI is 0.95. Future studies will test the psychometric properties of the tool.
The SCOAAI showed excellent content validity, confirming its usefulness for assessing self-care behaviors for patients on oral anticancer agents. By implementing this instrument, nurses could define and implement targeted interventions for improving self-care and obtaining more positive outcomes (eg, better quality of life, reduced hospitalizations and emergency department visits).
开发和检验口服抗癌药物自我护理指数（SCOAAI）的内容效度。
SCOAAI 项目根据共识基础的健康测量工具选择标准（COSMIN）标准制定。慢性病自我护理的中程理论为项目生成提供了信息。采用了四阶段程序：第 1 阶段：根据先前的系统评价和定性研究创建项目；第 2 阶段：通过与临床专家和患者进行定性访谈确定 SCOAAI 的可理解性和全面性（第 3 阶段）；第 4 阶段：然后通过在线调查向一组临床专家发放 SCOAAI 以计算内容效度指数（CVI）。
SCOAAI 的第 1 版包含 27 个项目。5 位临床专家和 10 位患者测试了说明、项目和反应选项的全面性和可理解性。53 位专家（71.7%为女性，平均每位患者口服抗癌药物的经验为 5.8 年[标准差±0.2]；66%为护士）参与了在线调查以进行内容效度测试。SCOAAI 的最终版本包含 32 个项目。项目 CVI 范围在 0.79 到 1 之间；平均量表 CVI 为 0.95。未来的研究将检验工具的心理测量特性。
SCOAAI 表现出极好的内容效度，证实了其在评估口服抗癌药物患者自我护理行为方面的有用性。通过实施该工具，护士可以确定并实施有针对性的干预措施，以改善自我护理并获得更积极的结果（例如，更好的生活质量、减少住院和急诊就诊）。
