Randomized experiments are a strong design for establishing impact evidence because the random assignment mechanism theoretically allows confidence in attributing group differences to the intervention. Growth of randomized experiments within educational studies has been widely documented. However, randomized experiments within education have…

Implementation of evidence-based practices for autistic students must be informed by robust research literature. Randomized-controlled trials (RCTs) are often considered a "gold standard" methodology for determining the effectiveness of interventions. However, the complex nature of schools presents challenges for implementing successful…

Background: As people with Parkinson's experience progressive communication changes, effective, implementable speech and language therapy (SLT) interventions are needed. Process evaluations alongside pragmatic randomised controlled trials (RCTs) are of clinical value if they describe, compare and understand the implementation of trial…

Background: Schools need to implement universal student supports that prevent social, emotional, and behavioral difficulties; minimize associated risks; and promote social, emotional, and behavioral competencies. The purpose of this study is to examine the efficacy of the Helping Educational Leaders Mobilize Evidence (HELM) implementation strategy…

Partnering with governments to co-design pilot interventions and embed them in local bureaucratic systems is increasingly seen as "best practice" on grounds of scalability and sustainability. This paper reports on a pilot program that was co-designed with, and embedded within, the Elementary and Secondary Education Department in…

This article examines the implementation, participation rates, and potential determinants of participation in the digital addiction prevention program "ready4life." A two-arm cluster-randomized trial recruited German vocational students via class-based strategies. Intervention group received 16 weeks of in-app coaching; the control group…

The growing understanding of the deleterious effects of childhood trauma has led policymakers to encourage the integration of trauma-informed system approaches into educational settings. The National Childhood Traumatic Stress Network has created a framework that integrates trauma-responsive school policies, practices, and programs at each tier of…

In multisite trials, learning about treatment effect variation across sites is critical for understanding where and for whom a program works. Unadjusted comparisons, however, capture "compositional" differences in the distributions of unit-level features as well as "contextual" differences in site-level features, including…

When a researcher tests an educational program, product, or policy in a randomized controlled trial and detects a significant effect on an outcome, the intervention is usually classified as something that "works." When expected effects are not found, there is seldom an orderly and transparent analysis of plausible reasons why.…

Although advances have been made in facilitating the implementation of evidence-based treatments, little is known about the most effective way to sustain their use over time. The current study examined the sustainability of one evidence-based treatment, Parent-Child Interaction Therapy (PCIT), following a statewide implementation trial testing…

Background: When well-designed and implemented, cluster randomized trials can meet the high standards federal agencies and other funders increasingly require for evidence on the effectiveness of school health programs and services. However, designing and implementing these studies can present more challenges than at first appears. Methods: I…

This study presents findings from a 58 high-school group-randomized controlled trial testing the effectiveness of training in a multitiered system of supports for behavior (MTSS-B) framework, which was leveraged to reduce students' risk for emotional and behavior disorders. The trial tested the impact of MTSS-B, which included (a) training in the…

Research in the UK suggests that multi-componential interventions focusing on language and pre-literacy skills can improve children's reading and language skills. However, simple translations of such programmes may not produce equivalent effects in diverse communities. The reasons for this are multi-faceted and include factors beyond the rationale…

Background: While implementation studies in aphasia management have shown promising improvements to clinical practice, it is currently unknown if aphasia implementation outcomes are sustained and what factors may influence clinical sustainability. Aims: To evaluate the sustainment (i.e., sustained improvement of aphasia management practices and…

General and long-term outcomes of functional analysis training have not yet been reported. Within a randomized control trial, we trained 18 behavior analytic practitioners to interview caregivers, design and then conduct a personalized analysis as a part of a practical functional assessment (PFA). Participants were randomly assigned to groups, and…
