BACKGROUND
Current evidence suggests that many adolescents with juvenile idiopathic arthritis (JIA) do not successfully transfer to adult care, which can result in adverse health outcomes. Although a growing number of clinical programs have been designed to support healthcare transition, there is a lack of psychometrically sound instruments to evaluate their impact on development of transition-related knowledge and skills in youth with JIA. The purpose of this study was to develop and validate RACER (Readiness for Adult Care in Rheumatology), a self-administered instrument designed to measure stages of readiness for key transition-related skills in adolescents with JIA.
METHODS
A phased approach was used to develop and evaluate the validity and reliability of RACER. Phase 1 A was a consensus conference with 19 key stakeholders to inform instrument domains and items. Phase 1B determined initial content validity using a sample of 30 adolescents with JIA and 15 clinical and research experts. Finally, Phase 2 was a prospective cohort study with repeated measures to evaluate the internal consistency, test-retest reliability, construct validity and responsiveness of the instrument within a sample of adolescents with JIA.
RESULTS
In Phase 1 A, initial item generation yielded a total of 242 items across six domains from the consensus conference, which was subsequently reduced to a 32-item instrument. Phase 1B established the content validity of the instrument in adolescents with JIA. In the Phase 2 study, with a sample of 96 adolescents, the RACER instrument exhibited good internal consistency in five of its six subscales (Cronbach's α > 0.7), and strong test-retest reliability between the first two administrations (ICC = 0.83). It also showed robust convergent validity by highly correlating with measures of self-management (SMSAG, rho = 0.73) and transition (TRANSITION-Q, rho = 0.76). The RACER was not correlated with unrelated measures (discriminant validity; PedsQL, rho = 0.14). The RACER scores increased significantly over time as expected, supporting measure responsiveness.
CONCLUSIONS
The RACER is a reliable and valid instrument which is sensitive to change for assessing transition readiness in adolescents with JIA.
背景
目前的证据表明，许多患有幼年特发性关节炎（JIA）的青少年未能成功过渡到成人护理，这可能导致不良的健康结果。尽管越来越多的临床项目旨在支持医疗过渡，但缺乏衡量青少年 JIA 过渡相关知识和技能发展的心理测量学上健全的工具。本研究的目的是开发和验证 RACER（风湿病成人护理准备），这是一种自我管理工具，旨在衡量青少年 JIA 关键过渡相关技能的准备阶段。
方法
采用分阶段方法开发和评估 RACER 的有效性和可靠性。第 1 阶段 A 是一次共识会议，有 19 位主要利益相关者参加，为工具领域和项目提供信息。第 1 阶段 B 使用 30 名 JIA 青少年和 15 名临床和研究专家的样本确定了初始内容有效性。最后，第 2 阶段是一项前瞻性队列研究，采用重复测量方法评估 RACER 在 JIA 青少年样本中的内部一致性、重测信度、结构有效性和反应性。
结果
在第 1 阶段 A 中，初始项目生成共产生了来自共识会议的六个领域的 242 个项目，随后减少到 32 个项目。第 1 阶段 B 确定了青少年 JIA 中该工具的内容有效性。在第 2 阶段研究中，使用 96 名青少年的样本，RACER 仪器在其六个子量表中的五个子量表中表现出良好的内部一致性（Cronbach's α>0.7），并且在第一次和第二次测试之间具有很强的重测信度（ICC=0.83）。它还通过与自我管理（SMSAG，rho=0.73）和过渡（TRANSITION-Q，rho=0.76）的高度相关表现出强大的收敛有效性。RACER 与不相关的测量值（判别有效性；PedsQL，rho=0.14）不相关。正如预期的那样，RACER 得分随时间显著增加，支持了测量的反应性。
结论
RACER 是一种可靠且有效的工具，可用于评估青少年 JIA 的过渡准备情况。
