Arman Miri; Akram Karimi-Shahanjarini; Maryam Afshari; Saeed Bashirian; Leili Tapak – Health Education Research, 2024
This systematic review aimed to assess the features and effectiveness of individual-level randomized controlled trials targeting COVID-19 misinformation. The selection process included rigorous criteria, resulting in the inclusion of 24 individual studies from 21 papers. The majority of studies were conducted in high-income countries, with the…

Eli Marie Killi; Ingvil Laberg Holthe; Nina Rohrer-Baumgartner; Shari L. Wade; Marianne Løvstad; Edel Jannecke Svendsen – Journal of Research in Special Educational Needs, 2025
Children living with the consequences of paediatric acquired brain injury (pABI) may experience persistent challenges that impact their social interactions, academic performance and community integration. Participating in activities is of paramount importance for the development of social and academic skills. The participants in this qualitative…

Risk of bias (RoB) assessment is essential to the systematic review methodology. The new version of the Cochrane RoB tool for randomized trials (RoB 2) was published in 2019 to address limitations identified since the first version of the tool was published in 2008 and to increase the reliability of assessments. This study analyzed the frequency…

Debbie L. Hahs-Vaughn; Christine Depies DeStefano; Christopher D. Charles; Mary Little – American Journal of Evaluation, 2025
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…

Peter Z. Schochet – Journal of Educational and Behavioral Statistics, 2025
Random encouragement designs evaluate treatments that aim to increase participation in a program or activity. These randomized controlled trials (RCTs) can also assess the mediated effects of participation itself on longer term outcomes using a complier average causal effect (CACE) estimation framework. This article considers power analysis…

Tieme W. P. Janssen; Nienke van Atteveldt – British Journal of Educational Psychology, 2025
Background: Although past research demonstrated growth mindset interventions to improve school outcomes, effects were small. This may be due to the "theoretical" nature of psychosocial techniques (e.g., reading about brain plasticity), which may not be optimally convincing for students. Aims: To address this issue and improve…

Alexis M. Brewe; Ligia Antezana; Corinne N. Carlton; Denis Gracanin; John A. Richey; Inyoung Kim; Susan W. White – Journal of Autism and Developmental Disorders, 2025
Purpose: Many individuals with autism spectrum disorder (ASD) experience challenges with facial emotion recognition (FER), which may exacerbate social difficulties in ASD. Few studies have examined whether FER can be experimentally manipulated and improved for autistic people. This study utilized a randomized controlled trial design to examine…

Nejstgaard, Camilla Hansen; Laursen, David Ruben Teindl; Lundh, Andreas; Hróbjartsson, Asbjørn – Research Synthesis Methods, 2023
We investigated to which degree commercial funding is associated with estimated intervention effects in randomized trials. We included meta-epidemiological studies with published data on the association between commercial funding and results or conclusions of randomized trials. We searched five databases and other sources. We selected one result…

Zuchao Shen; Ben Kelcey – Society for Research on Educational Effectiveness, 2023
I. Purpose of the Study: Detecting whether interventions work or not (through main effect analysis) can provide empirical evidence regarding the causal linkage between malleable factors (e.g., interventions) and learner outcomes. In complement, moderation analyses help delineate for whom and under what conditions intervention effects are most…

James Soland – Journal of Research on Educational Effectiveness, 2024
When randomized control trials are not possible, quasi-experimental methods often represent the gold standard. One quasi-experimental method is difference-in-difference (DiD), which compares changes in outcomes before and after treatment across groups to estimate a causal effect. DiD researchers often use fairly exhaustive robustness checks to…

Justin Boutilier; Jonas Jonasson; Hannah Li; Erez Yoeli – Society for Research on Educational Effectiveness, 2024
Background: Randomized controlled trials (RCTs), or experiments, are the gold standard for intervention evaluation. However, the main appeal of RCTs--the clean identification of causal effects--can be compromised by interference, when one subject's actions can influence another subject's behavior or outcomes. In this paper, we formalize and study…

Clarke; Natalie Ives; Sue Jowett; Caroline Rick; Rebecca Woolley; Catherine M. Sackley – International Journal of Language & Communication Disorders, 2025
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…

Timothy Lycurgus; Daniel Almirall – Society for Research on Educational Effectiveness, 2024
Background: Education scientists are increasingly interested in constructing interventions that are adaptive over time to suit the evolving needs of students, classrooms, or schools. Such "adaptive interventions" (also referred to as dynamic treatment regimens or dynamic instructional regimes) determine which treatment should be offered…

Wei Li; Yanli Xie; Dung Pham; Nianbo Dong; Jessaca Spybrook; Benjamin Kelcey – Asia Pacific Education Review, 2024
Cluster randomized trials (CRTs) are commonly used to evaluate the causal effects of educational interventions, where the entire clusters (e.g., schools) are randomly assigned to treatment or control conditions. This study introduces statistical methods for designing and analyzing two-level (e.g., students nested within schools) and three-level…

Background: Despite many adolescents experiencing mental health concerns, a substantial portion lack access to evidence-based treatments (EBTs) for psychopathology; this issue is magnified for adolescents belonging to communities considered marginalized. One way to ameliorate this is by adapting existent EBTs--typically delivered in research…
