Caregivers of individuals with traumatic brain injury (TBI) often feel pressure to maintain the appearance that they are emotionally well adjusted, despite feelings to the contrary. Because there are currently no measures examining this construct, this article focuses on the development of a new measure that is specific to caregivers of people with TBI.
A total of 533 caregivers of civilians with TBI ( = 218) or service members/veterans (SMVs) with TBI ( = 315) completed 43 emotional suppression items, as well as other patient-reported outcomes and an estimate of the functional ability of the person with TBI.
Exploratory and confirmatory factor analyses supported the retention of 25 items. Graded response model (GRM) analyses and differential item functioning (DIF) studies supported the retention of 21 items in the final measure. Expert review and GRM calibration data were used to develop a 6-item static short form (SF) and program a computer adaptive test (CAT). Internal consistency was excellent for both the CAT and SF (reliabilities ≥ 0.91); 3-week test-retest stability was good (all intraclass correlations ≥ 0.89). Convergent validity was supported by moderate associations between TBI-CareQOL Emotional Suppression and related measures (s from 0.47 to 0.59); discriminant validity was supported by small correlations between Emotional Suppression and positive aspects of caregiving and physical health (s from 0.14 to 0.28). Known-groups validity was also supported.
The new TBI-CareQOL Emotional Suppression CAT and 6-item short form is the first self-report measure of this construct in this population. Our findings suggest this new measure has strong psychometric properties. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
创伤性脑损伤（TBI）患者的照顾者常常感到有压力，需要保持情绪良好的外表，尽管他们的感受可能恰恰相反。由于目前没有衡量这一结构的方法，本文专注于开发一种专门针对 TBI 患者照顾者的新测量方法。
共有 533 名平民 TBI 照顾者（=218）或军人/退伍军人（SMV）TBI 照顾者（=315）完成了 43 项情绪抑制项目，以及其他患者报告的结果和对 TBI 患者功能能力的估计。
探索性和验证性因素分析支持保留 25 项。等级反应模型（GRM）分析和差异项目功能（DIF）研究支持保留最终测量中的 21 项。专家审查和 GRM 校准数据用于开发 6 项静态简短形式（SF）和编程计算机自适应测试（CAT）。CAT 和 SF 的内部一致性都非常好（信度≥0.91）；3 周的重测稳定性良好（所有组内相关系数≥0.89）。TBI-CareQOL 情绪抑制与相关测量之间的中度关联支持了收敛效度（s 从 0.47 到 0.59）；情绪抑制与照顾的积极方面和身体健康之间的小相关支持了区分效度（s 从 0.14 到 0.28）。也支持了已知群体的有效性。
新的 TBI-CareQOL 情绪抑制 CAT 和 6 项简短形式是该人群中该结构的第一个自我报告测量方法。我们的研究结果表明，这种新的测量方法具有很强的心理测量特性。（PsycInfo 数据库记录（c）2020 APA，保留所有权利）。
