Intentions play a central role in numerous empirically supported theories of behavior and behavior change and have been identified as a potentially important antecedent to successful evidence-based treatment (EBT) implementation. Despite this, few measures of mental health clinicians' EBT intentions exist and available measures have not been subject to thorough psychometric evaluation or testing. This paper evaluates the psychometric properties of the evidence-based treatment intentions (EBTI) scale, a new measure of mental health clinicians' intentions to adopt EBTs.
The study evaluates the reliability and validity of inferences made with the EBTI using multi-method, multi-informant criterion variables collected over 12 months from a sample of 197 mental health clinicians delivering services in 13 mental health agencies. Structural, predictive, and discriminant validity evidence is assessed.
Findings support the EBTI's factor structure (χ (2) = 3.96, df = 5, p = .556) and internal consistency reliability (α = .80). Predictive validity evidence was provided by robust and significant associations between EBTI scores and clinicians' observer-reported attendance at a voluntary EBT workshop at a 1-month follow-up (OR = 1.92, p < .05), self-reported EBT adoption at a 12-month follow-up (R (2) = .17, p < .001), and self-reported use of EBTs with clients at a 12-month follow-up (R (2) = .25, p < .001). Discriminant validity evidence was provided by small associations with clinicians' concurrently measured psychological work climate perceptions of functionality (R (2) = .06, p < .05), engagement (R (2) = .06, p < .05), and stress (R (2) = .00, ns).
The EBTI is a practical and theoretically grounded measure of mental health clinicians' EBT intentions. Scores on the EBTI provide a basis for valid inferences regarding mental health clinicians' intentions to adopt EBTs. Discussion focuses on research and practice applications.
意图在众多经实证支持的行为及行为改变理论中发挥着核心作用，并且已被确定为成功实施循证治疗（EBT）的一个潜在重要前提。尽管如此，针对心理健康临床医生的EBT意图的测量方法却很少，现有的测量方法也未经过全面的心理测量评估或测试。本文评估了循证治疗意图（EBTI）量表的心理测量特性，这是一种用于测量心理健康临床医生采用EBT意图的新方法。
本研究使用多方法、多信息源标准变量评估了EBTI的信效度，这些变量是在12个月内从197名在13个心理健康机构提供服务的心理健康临床医生样本中收集的。评估了结构效度、预测效度和区分效度证据。
研究结果支持EBTI的因子结构（χ (2) = 3.96，自由度 = 5，p = .556）和内部一致性信度（α = .80）。预测效度证据来自于EBTI得分与临床医生在1个月随访时观察者报告的参加自愿EBT工作坊情况之间的稳健且显著的关联（比值比 = 1.92，p < .05）、在12个月随访时自我报告的EBT采用情况（R (2) = .17，p < .001）以及在12个月随访时自我报告的与客户使用EBT的情况（R (2) = .25，p < .001）。区分效度证据来自于与临床医生同时测量的心理工作氛围功能性感知（R (2) = .06，p < .05）、参与度（R (2) = .06，p < .05）和压力（R (2) = .00，无显著性差异）之间的小关联。
EBTI是一种实用且基于理论的测量心理健康临床医生EBT意图的方法。EBTI得分可为关于心理健康临床医生采用EBT意图的有效推断提供依据。讨论集中在研究和实践应用方面。
