To link scores on commonly used measures of anxiety (7-item Generalized Anxiety Disorder Scale; GAD-7) and depression (9-item Patient Health Questionnaire; PHQ-9) to the Traumatic Brain Injury Quality of Life (TBI-QOL) measurement system.
5 Traumatic Brain Injury Model Systems.
A total of 385 individuals with traumatic brain injury (TBI) (31% complicated mild; 14% moderate; and 54% severe).
Observational cohort.
GAD-7, PHQ-9, TBI-QOL Anxiety v1.0 and TBI-QOL Depression v1.0.
Item response theory-based linking methods were used to create crosswalk tables that convert scores on the GAD-7 to the TBI-QOL Anxiety metric and scores on the PHQ-9 to the TBI-QOL Depression metric. Comparisons between actual and crosswalked scores suggest that the linkages were successful and are appropriate for group-level analysis. Linking functions closely mirror crosswalks between the GAD-7/PHQ-9 and the Patient-Reported Outcomes Measurement Information System (PROMIS), suggesting that general population linkages are similar to those from a TBI sample.
Researchers and clinicians can use the crosswalk tables to transform scores on the GAD-7 and the PHQ-9 to the TBI-QOL metric for group-level analyses.
将常用焦虑量表（7 项广泛性焦虑障碍量表；GAD-7）和抑郁量表（9 项患者健康问卷；PHQ-9）的得分与创伤性脑损伤生活质量（TBI-QOL）测量系统联系起来。
5 个创伤性脑损伤模型系统。
共 385 名创伤性脑损伤（TBI）患者（31%为复杂轻度；14%为中度；54%为重度）。
观察性队列。
GAD-7、PHQ-9、TBI-QOL 焦虑 v1.0 和 TBI-QOL 抑郁 v1.0。
使用基于项目反应理论的关联方法创建了转换表，将 GAD-7 的分数转换为 TBI-QOL 焦虑量表的分数，将 PHQ-9 的分数转换为 TBI-QOL 抑郁量表的分数。实际分数与转换分数的比较表明，关联是成功的，适用于群体水平分析。关联函数与 GAD-7/PHQ-9 和患者报告结果测量信息系统（PROMIS）之间的转换密切相关，这表明一般人群的关联与创伤性脑损伤样本的关联相似。
研究人员和临床医生可以使用转换表将 GAD-7 和 PHQ-9 的分数转换为 TBI-QOL 量表，以便进行群体水平分析。
