As schools increasingly implement multitiered systems of support, there is a pressing need to develop psychometrically sound implementation fidelity measures. The interconnected systems framework (ISF) is a multitiered model blending systems of positive behavioral interventions and supports with promotion, prevention, and intervention strategies of school mental health. The ISF is being implemented in communities across the United States with ongoing evaluation in several randomized controlled trials. The ISF-Implementation Inventory (ISF-II) was developed to measure fidelity of the ISF within a school building. We conducted a national validation study including completion of the ISF-II by 398 educators in 49 schools, 16 school districts, and 9 states. Results indicate the ISF-II produces scores that are internally consistent and structurally valid when items are organized into a three-tiered model. Additionally, the ISF-II was rated as feasible, acceptable, and beneficial. Limitations of the study, including the need for additional psychometric testing, are discussed in light of these results that suggest educators and researchers, alike, should feel confident in using the ISF-II as a measure of ISF implementation quality.

随着学校越来越多地实施多层次的支持系统，迫切需要开发具有心理测量学意义的实施保真度衡量标准。互联系统框架（ISF）是一个多层次的模型，融合了积极行为干预和支持系统，以及学校心理健康的促进、预防和干预策略。ISF 正在美国各地的社区中实施，并在几个随机对照试验中进行了正在进行的评估。ISF-实施清单（ISF-II）是为了衡量学校建筑内 ISF 的保真度而开发的。我们进行了一项全国性的验证研究，包括 49 所学校、16 个学区和 9 个州的 398 名教育工作者完成 ISF-II。结果表明，当项目按三层模型组织时，ISF-II 产生的分数具有内部一致性和结构有效性。此外，ISF-II 被评为可行、可接受和有益的。鉴于这些结果表明教育工作者和研究人员都应该有信心使用 ISF-II 作为 ISF 实施质量的衡量标准，讨论了研究的局限性，包括需要进行额外的心理测量测试。
