The literature on trauma-informed care practices (TIC) indicates that this framework is beneficial for young people, carers, and staff. However, a significant gap in the literature and practice is the absence of psychometrically sound scales to measure carer adherence to TIC principles. Emerging evidence suggests that TIC practices shift carer attitudes and beliefs, which mediate positive outcomes for both carers and young people.
To develop a theoretically comprehensive and psychometrically sound measure of carer TIC beliefs using Rasch methodology.
Active carers (N = 719, M = 43 years, SD = 10.7 years) from online support groups in Australia, Canada, the United States of America, the United Kingdom, and the Republic of Ireland completed the questionnaire online.
Based on previous research (e.g., limitations of the Trauma-Informed Belief Scale-Brief [TIBS-B]; Beehag, Dryer, et al., 2023a) and a scoping review of the TIC literature (Beehag, 2023), 61 candidate items were created that covered the three main characteristics of carer-related TIC theory (i.e., beliefs on TIC strategies to manage trauma symptoms, beliefs on the impact of adverse childhood experiences (ACE), and beliefs on the importance of self-care/reflection). The resulting data was subjected to Rasch analyses.
Following analyses and minor modifications, a 35-item version of the questionnaire was confirmed, which fitted the Rasch model and demonstrated unidimensionality, reasonable targeting, and sound internal consistency reliability (Person Separation Index = 0.81).
The TIBS-C is a psychometrically sound measure of child welfare carer TIC beliefs. Future studies are needed to provide further evidence of its validity (e.g., predictive validity), reliability (e.g., test-retest reliability) and clinical utility.
创伤知情照护实践（TIC）的文献表明，该框架对年轻人、照顾者和工作人员都有益。然而，文献和实践中的一个重大差距是，缺乏衡量照顾者遵循 TIC 原则的心理测量学上合理的量表。新出现的证据表明，TIC 实践改变了照顾者的态度和信念，这对照顾者和年轻人都产生了积极的结果。
使用 Rasch 方法制定一个理论上全面且心理测量学上合理的照顾者 TIC 信念测量工具。
来自澳大利亚、加拿大、美国、英国和爱尔兰在线支持小组的活跃照顾者（N=719，M=43 岁，SD=10.7 岁）在线完成了问卷。
基于先前的研究（例如，创伤知情信念量表-简短版的局限性[TIBS-B]；Beehag、Dryer 等人，2023a）和 TIC 文献的范围综述（Beehag，2023），创建了 61 个候选条目，涵盖了照顾者相关 TIC 理论的三个主要特征（即，管理创伤症状的 TIC 策略的信念、对不良童年经历（ACE）的影响的信念以及自我照顾/反思的重要性的信念）。所得数据进行了 Rasch 分析。
经过分析和小的修改，确认了问卷的 35 个项目版本，该版本符合 Rasch 模型，表现出一维性、合理的针对性和良好的内部一致性可靠性（个体分离指数=0.81）。
TIBS-C 是一种心理测量学上合理的儿童福利照顾者 TIC 信念测量工具。需要进一步的研究来提供其有效性（例如，预测有效性）、可靠性（例如，重测信度）和临床实用性的进一步证据。
