Intervention fidelity is the extent to which an individual- or systems-level student intervention is delivered comprehensively in a manner aligned with the initial plan. This first installment in a three-part series on intervention fidelity highlights the importance of ensuring classroom supports are implemented as intended and introduces…

This study explored school psychologists' practices in the areas of developing behavior intervention plans (BIPs), conducting functional behavior assessments (FBAs), and behavioral consultation. Practitioners were asked to rate their level of confidence in the implementation with fidelity of the last BIP they developed. Relationships between these…

Naturalistic developmental behavioral interventions (NDBIs) are considered one of the best practices for autistic children and their families. Most NDBIs include a component of providing training and/or coaching to caregivers to enhance skill acquisition and generalization. The procedures to implement these NDBIs are often clearly delineated in…

A systematic review and meta-analysis were utilised to explore the methodological quality, program fidelity, and efficacy of social skills group programs (SSGPs) aiming to support autistic adolescents in navigating their everyday social worlds. The study evaluated the methodological quality and theoretical fidelity of studies, with a random effect…

To examine treatment fidelity in a randomized controlled trial of indicated school-based cognitive-behavioral therapy (CBT) delivered in groups to youth with anxiety. We investigated whether adherence and competence (a) differed across brief and standard-length CBT, and (b) if adherence and competence predicted change in anxiety symptoms and…

Supervising behavior technicians in the implementation of services derived from the science of applied behavior analysis with children diagnosed with autism spectrum disorder (ASD) is a common practice for behavior analysts. However, there is limited training available on supervision strategies for those applying this model of services. Lack of…

This commentary for the special issue on integrity measurement in school mental health research advocates that pragmatism is centralized in implementation and fidelity efforts for evidence-based behavioral interventions (EBIs). Specific recommendations include focusing on augmenting existing practices and core element interventions; developing…

Younger siblings of autistic children are at a high likelihood (HL) of autism, language, and/or cognitive delays. Vocal complexity, a continuous measure of the developmental maturity of vocal communication, is facilitated by parent-child interaction and predicts language outcomes. This study examined whether parents' intervention fidelity to…

A single-case multiple baseline design across three families was used to evaluate the impact of a manualized Prevent-Teach-Reinforce for Families (PTR-F) process for addressing challenging behavior (CB) when delivered in a remote format (PTR-F: R). Results across three U.S. families showed that (a) a functional relation existed between parent…

The effectiveness of a behavior intervention package depends heavily on the ability of authentic educators to implement procedures with fidelity. However, much of the training literature focuses on teaching educators to implement procedures with relatively few components (Kirkpatrick Journal of Behavioral Education 28(3): 344-361, 2019). We used a…

Individuals with disabilities may exhibit dangerous behavior such as physical aggression and self-injury. Determining the environmental variables maintaining dangerous behavior using a functional behavior assessment can inform treatment in teaching individuals with disabilities functionally equivalent replacement behavior. However, logistic…

The present pilot study explored the feasibility, acceptability, and efficacy of a multicomponent social narrative intervention to teach behavioral expectations. We conducted a multiple probe design across three children to evaluate the effects of the intervention on student behavior. In addition, we measured the fidelity of teacher implementation…

The publicly funded early intervention program for preschoolers with autism spectrum disorder (ASD) in Nova Scotia, Canada, uses the pivotal response treatment (PRT) model. Parents are coached in use of PRT strategies during their children's first week of treatment. We explored whether parents of older preschoolers with limited verbal ability…

Previous research has shown that low procedural fidelity can lead to decreased effectiveness and efficiency of skill acquisition during discrete-trial instruction. Previous research has also found that procedural fidelity may be substantially lower when a supervisor is not present to observe the session. Finding a socially acceptable, effective,…

As the most common setting where youth access behavioral healthcare, the education sector frequently employs training and follow-up consultation as cornerstone implementation strategies to promote the implementation of evidence-based practices (EBPs). However, these strategies alone are not sufficient to promote desirable implementation (e.g.,…
