To establish the reliability and validity of the newly developed TBI-CareQOL patient-reported outcome (PRO) measures in caregivers of civilians and service members/veterans (SMVs) with traumatic brain injury (TBI) so that they can be used with confidence in clinical research and practice.
Computer-based surveys delivered through an on-line data capture platform.
Three TBI Model Systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility.
Caregivers (N=560) of individuals with TBI; this included 2 different study samples: 344 caregivers of civilians with TBI and 216 caregivers of SMVs with TBI.
Not Applicable.
Five Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) item banks.
Reliabilities for the TBI-CareQOL measures were excellent (all Cronbach's α >.88); 3-week test-retest reliability ranged from .75 to .90 across the 2 samples. Convergent validity was supported by moderate to high associations among the TBI-CareQOL measures and moderate correlations between the TBI-CareQOL measures and other measures of health-related quality of life (HRQOL) and caregiver burden. Discriminant validity was supported by low correlations between the TBI-CareQOL measures and less-related constructs (eg, caregiver satisfaction). Known-groups validity was supported: caregivers of individuals that were low functioning had worse HRQOL than caregivers of high-functioning individuals.
Results provide psychometric support for the new TBI-CareQOL item banks. As such, these measures fill a significant gap in the caregiver literature where sensitive PRO measures that capture changes in HRQOL are needed to detect improvements for interventions designed to assist family caregivers.
确定新开发的创伤性脑损伤（TBI）患者报告结局（PRO）测量工具 TBI-CareQOL 在民用和军人/退伍军人（SMV）TBI 照顾者中的可靠性和有效性，以便在临床研究和实践中自信地使用。
通过在线数据采集平台提供基于计算机的调查。
三个 TBI 模型系统康复医院、一个学术医疗中心和一个军事医疗设施。
TBI 患者的照顾者（N=560）；这包括 2 个不同的研究样本：344 名民用 TBI 照顾者和 216 名 SMV TBI 照顾者。
不适用。
5 个创伤性脑损伤照顾者生活质量（TBI-CareQOL）项目库。
TBI-CareQOL 测量的可靠性非常好（所有 Cronbach's α>0.88）；在这 2 个样本中，3 周的重测信度范围为 0.75 至 0.90。TBI-CareQOL 测量与 TBI-CareQOL 测量与其他健康相关生活质量（HRQOL）和照顾者负担测量之间的中度至高度相关性支持了收敛效度。区分效度得到了 TBI-CareQOL 测量与相关性较低的结构（例如，照顾者满意度）之间的低相关性的支持。已知组有效性得到支持：功能较低的个体的照顾者的 HRQOL 比功能较高的个体的照顾者差。
结果为新的 TBI-CareQOL 项目库提供了心理测量学支持。因此，这些措施填补了照顾者文献中的一个重要空白，需要敏感的 PRO 措施来捕捉 HRQOL 的变化，以检测旨在帮助家庭照顾者的干预措施的改善。
