In school settings, nurses lead efforts to improve the student health and well-being to support academic success. Nurses are guided by evidenced-based practice and data to inform care decisions. The randomized controlled trial (RCT) is considered the gold standard of scientific rigor for clinical trials. RCTs are critical to the development of…

There has been increased interest in recent years regarding the utility of imported universal prevention and promotion (P&P) programmes in UK schools, many of which have a coaching model attached. However, there have been relatively few studies exploring the cultural transferability and social validity of these models, even though evidence…

A non-inferiority design accepts the possibility of some efficacy loss, as part of a "successful", statistically significant result. That loss may be excessive when the non-inferiority threshold is lenient. However, even stringent significance thresholds and safety monitoring may fail to adequately protect study participants when the…

This study was designed to evaluate the effectiveness of a brief Alcohol Expectancy Challenge, with the aim of reducing the prevalence of alcohol consumption amongst Maltese teenagers.119 students were randomly allocated to a control or a 3-hour expectancy challenge session. Alcohol consumption and alcohol expectancies were investigated via a…

This paper presents findings from a systematic literature review that explored the delivery arrangements of school-based reading interventions for struggling readers aged 5-8 years. Databases were searched for published and unpublished studies from 1970 to 2017, which employed a randomised controlled trial or quasi-experimental design. Sixty-four…

Ainsworth et al.'s paper "Sources of Bias in Outcome Assessment in Randomised Controlled Trials: A Case Study" examines alternative accounts for a large difference in effect size between 2 outcomes in the same intervention evaluation. It argues that the probable explanation relates to masking: Only one outcome measure was administered by…

The efficacy of attention training paradigms is influenced by many factors, including the specificity of targeted cognitive processes, accuracy of outcome measures, accessibility to specialized populations, and adaptability to user capability. These issues are increasingly significant when working with children diagnosed with neurodevelopmental…

The field of educational research encompasses a vast array of paradigmatic and methodological perspectives. Arguably, this range has both expanded and limited our achievements in the name of educational research. In Australia, the ascendancy of certain research perspectives has profoundly shaped the field and its likely future. We (are expected…

Recent studies show cluster randomized trials may be well powered to detect mediation or indirect effects in multilevel settings. However, literature has rarely provided guidance on designing cluster-randomized trials aim to assess indirect effects. In this study, we developed closed-form expression to estimate the variance of and the statistical…

Research using mind-body practices in autism is limited but suggests a trend for ruminative reduction and improved behavioral-emotional outcomes. Following random assignment (N = 67), effects of a weekly six-session pilot yoga-based group program combined with third-wave cognitive behavioral therapy elements on self-regulation for children on the…

To plan cluster-randomized trials with sufficient statistical power to detect intervention effects on student achievement, researchers need multilevel design parameters, including measures of between-classroom and between-school differences and the amounts of variance explained by covariates at the student, classroom, and school level. Previous…

Since the 1990s, there have been repeated calls for the systematic use of randomised controlled trials (RCTs) to inform educational decision-making. The advent of the Education Endowment Foundation (EEF) -- described as England's What Works Centre for Education -- in 2011 has made this a reality in England: by 2020, over a third of English schools…

Randomized controlled trials (RCTs) admit unconfounded design-based inference--randomization largely justifies the assumptions underlying statistical effect estimates--but often have limited sample sizes. However, researchers may have access to big observational data on covariates and outcomes from RCT non-participants. For example, data from A/B…

Within evidence-based education, results from randomised controlled trials (RCTs), and meta-analyses of them, are taken as reliable evidence for effectiveness -- they speak to "what works". Extending RCT results requires establishing that study samples and settings are representative of the intended target. Although widely recognised as…

Interventions often require multiple decisions to improve outcomes for every student. Whether the decision to implement a practice, tailor an existing protocol, or change approaches, these decisions should be based on individual variables and outcomes via a sequence of treatment. To develop adaptive interventions that have sufficient evidence to…
