Adverse events (AEs) are a leading cause of patient morbidity and mortality, greatly impacting healthcare providers' well-being (second victim (SV) phenomenon). Since it is not accurately captured by existing psychometric instruments, we developed a clinimetric instrument for assessing SVs' emotional distress before and after an AE.
Content validity and clinical utility of the WITHSTAND-PSY Questionnaire (WS-PSY-Q) were examined using cognitive interviews. Rasch analysis (n = 284) was applied for clinimetric assessment (i.e., construct, concurrent, and clinical validity, internal consistency), considering two crucial psychological facets of the SV phenomenon (1st: emotional impact of the AE, 2nd: current emotional state).
The Rasch partial credit model was used. The 1st facet demonstrated overall acceptable clinimetric properties with the subscale anxiety meeting clinimetric threshold values (e.g., all items with ordered thresholds, Loevinger's coefficient h ≥ 0.40; Person Separation Reliability Index (PSI) = 0.7). The 2nd facet showed overall better clinimetric properties for both subscales (e.g., h ≥ 0.40, PSI = 0.82 and 0.79, respectively; receiver operating characteristic area of 0.80 and 0.86, respectively). For both datasets, item fit statistics, except those for item 19, were within the critical range (z-score < ±2.5), and meaningful differential functioning analysis was observed for only 4 (out of 24) items. Local dependency was not observed, except for two item couples in the depression subscales.
The WS-PSY-Q is the first clinimetric tool assessing SVs' emotional distress. It should be regarded as part of the armamentarium used by clinicians to assess in-depth healthcare providers' psychological reactions in the aftermath of an AE to mitigate burnout and allostatic overload.
不良事件(AE)是导致患者发病率和死亡率的主要原因,极大地影响了医疗保健提供者的健康(第二受害者(SV)现象)。由于它不能被现有心理计量学工具准确捕捉,我们开发了一种临床工具来评估 AE 前后 SV 的情绪困扰。
使用认知访谈来检查 WITHSTAND-PSY 问卷(WS-PSY-Q)的内容有效性和临床实用性。应用 Rasch 分析(n = 284)进行临床评估(即结构、同时和临床有效性、内部一致性),考虑到 SV 现象的两个关键心理方面(1:AE 的情绪影响,2:当前情绪状态)。
使用 Rasch 部分信用模型。第一个方面表现出总体上可接受的临床计量学特性,焦虑子量表符合临床计量学阈值(例如,所有项目都有有序的阈值,Loevinger 系数 h≥0.40;个体分离可靠性指数(PSI)= 0.7)。第二个方面两个子量表的临床计量学特性都更好(例如,h≥0.40,PSI 分别为 0.82 和 0.79;接收者操作特征面积分别为 0.80 和 0.86)。对于两个数据集,除了项目 19 之外,项目拟合统计数据都在临界范围内(z 分数 < ±2.5),只有 4 个(24 个中的 4 个)项目观察到有意义的差异功能分析。除了抑郁子量表中的两个项目对之外,没有观察到局部依赖性。
WS-PSY-Q 是第一个评估 SV 情绪困扰的临床计量工具。它应该被视为临床医生用来评估 AE 后医疗保健提供者心理反应的工具的一部分,以减轻倦怠和全身过载。
