OBJECTIVE 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. DESIGN A total of 533 caregivers of civilians with TBI (n = 218) or service members/veterans (SMVs) with TBI (n = 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. RESULTS 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 (rs from 0.47 to 0.59); discriminant validity was supported by small correlations between Emotional Suppression and positive aspects of caregiving and physical health (rs from 0.14 to 0.28). Known-groups validity was also supported. CONCLUSIONS 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) 2019 APA, all rights reserved).

测量创伤性脑损伤成人照顾者的情绪抑制。

目标 创伤性脑损伤 (TBI) 患者的看护人经常感到压力，以保持他们情绪上调整良好的外表，尽管有相反的感觉。由于目前没有检查此结构的措施，因此本文重点介绍一项新措施的开发，该措施专门针对 TBI 患者的护理人员。设计 共有 533 名 TBI 平民 (n = 218) 或 TBI 军人/退伍军人 (SMV) 的护理人员 (n = 315) 完成了 43 个情绪抑制项目，以及其他患者报告的结果和功能评估TBI 患者的能力。结果 探索性和验证性因素分析支持保留 25 个项目。分级反应模型 (GRM) 分析和差异项目功能 (DIF) 研究支持在最终测量中保留 21 个项目。专家审查和 GRM 校准数据用于开发 6 项静态简表 (SF) 并编写计算机自适应测试 (CAT)。CAT 和 SF 的内部一致性都非常好（可靠性 ≥ 0.91）；3 周重测稳定性良好（所有组内相关性 ≥ 0.89）。TBI-CareQOL 情绪抑制和相关措施之间的适度关联支持收敛效度（rs 从 0.47 到 0.59）；情绪抑制与照顾和身体健康的积极方面之间的小相关性支持区分效度（rs 从 0.14 到 0.28）。已知组有效性也得到支持。结论 新的 TBI-CareQOL 情绪抑制 CAT 和 6 项简表是该人群中该结构的第一个自我报告测量。我们的研究结果表明，这种新措施具有很强的心理测量特性。（PsycINFO 数据库记录 (c) 2019 APA，保留所有权利）。
