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…

Micaela Sánchez-Martín; Marta Gutiérrez-Sánchez; Eva María Olmedo-Moreno; Fernando Navarro-Mateu – Cogent Education, 2024
Introduction: Concerns about the risk of bias (RoB) of Meta-analysis (MAs) have grown in parallel with the exponential increase in the number of publications in science. However, this has not been properly assessed in Education. The aims were to evaluate the RoB of MAs in Education and to identify potential predictors of a lower RoB. Methods:…

In network meta-analysis (NMA), we synthesize all relevant evidence about health outcomes with competing treatments. The evidence may come from randomized clinical trials (RCT) or non-randomized studies (NRS) as individual participant data (IPD) or as aggregate data (AD). We present a suite of Bayesian NMA and network meta-regression (NMR) models…

Petersen, Julie M.; Barrett, Malcolm; Ahrens, Katherine A.; Murray, Eleanor J.; Bryant, Allison S.; Hogue, Carol J.; Mumford, Sunni L.; Gadupudi, Salini; Fox, Matthew P.; Trinquart, Ludovic – Research Synthesis Methods, 2022
Systematic reviews and meta-analyses are essential for drawing conclusions regarding etiologic associations between exposures or interventions and health outcomes. Observational studies comprise a substantive source of the evidence base. One major threat to their validity is residual confounding, which may occur when component studies adjust for…

Jun Wang; Xue Wang; Qiyang Zhang; Hanhui Bao; Zhe Zhao; Amanda J. Neitzel – Society for Research on Educational Effectiveness, 2023
Background: Systematic reviews and meta-analyses of interventions can provide critical evidence for educators and policymakers by providing insights into the effectiveness of related interventions. The quality of included studies builds the foundation for a high-quality review, while bias in the included studies increases the risks of unreliable…

This individual participant data meta-analysis is the most intensive possible evaluation of the effectiveness of early intensive applied behaviour analysis-based interventions for pre-school autistic children compared with treatment as usual/eclectic interventions. Data from 491 participants (originally collected in 10 studies) were included.…

Borquist-Conlon, Debra S.; Maynard, Brandy R.; Brendel, Kristen Esposito; Farina, Anne S. J. – Research on Social Work Practice, 2019
Purpose: To examine the effects on anxiety of mindfulness-based interventions (MBIs) among youth with anxiety disorders. Method: Systematic review and meta-analytic procedures were employed to synthesize experimental and quasi-experimental studies authored between 1980 and 2015. Results: The search yielded five studies from five countries…

The Daily Report Card (DRC) is a commonly employed behavioral intervention for treating Attention Deficit Hyperactivity Disorder (ADHD) in schools. Much of the support for the DRC comes from single-case studies, which have traditionally received less attention than group studies. This lack of attention to single-case studies results in an…

Lazowski, Rory A.; Hulleman, Chris S. – Review of Educational Research, 2016
This meta-analysis provides an extensive and organized summary of intervention studies in education that are grounded in motivation theory. We identified 74 published and unpublished papers that experimentally manipulated an independent variable and measured an authentic educational outcome within an ecologically valid educational context. Our…

Valentine, Jeffrey C.; Thompson, Simon G. – Research Synthesis Methods, 2013
Background: Confounding caused by selection bias is often a key difference between non-randomized studies (NRS) and randomized controlled trials (RCTs) of interventions. Key methodological issues: In this third paper of the series, we consider issues relating to the inclusion of NRS in systematic reviews on the effects of interventions. We discuss…

Yeager, David S.; Miu, Adriana S.; Powers, Joseph; Dweck, Carol S. – Child Development, 2013
Past research has shown that hostile schemas and adverse experiences predict the hostile attributional bias. This research proposes that seemingly nonhostile beliefs (implicit theories about the malleability of personality) may also play a role in shaping it. Study 1 meta-analytically summarized 11 original tests of this hypothesis (N = 1,659),…

Panos, Patrick T.; Jackson, John W.; Hasan, Omar; Panos, Angelea – Research on Social Work Practice, 2014
Objective: The objective was to quantitatively and qualitatively examine the efficacy of DBT (e.g., decreasing life-threatening suicidal and parasuicidal acts, attrition, and depression) explicitly with borderline personality disorder (BPD) and using conservative assumptions and criteria, across treatment providers and settings. Method: Five…

Taylor, Joseph; Kowalski, Susan; Stuhlsatz, Molly; Wilson, Christopher; Spybrook, Jessaca – Society for Research on Educational Effectiveness, 2013
The purpose of this paper is to use both conceptual and statistical approaches to explore publication bias in recent causal effects studies in science education, and to draw from this exploration implications for researchers, journal reviewers, and journal editors. This paper fills a void in the "science education" literature as no…

Puzio, Kelly; Colby, Glenn T. – Journal of Research on Educational Effectiveness, 2013
We conducted a meta-analysis on the effectiveness of cooperative and collaborative learning to support enhanced literacy outcomes. Interventions considered were provided in regular education settings (i.e., not pull-out instruction) with students from Grades 2 through 12. Reviewing more than 30 years of literacy research, we located 18…

Heyvaert, M.; Maes, B.; Onghena, P. – Journal of Intellectual Disability Research, 2010
Background: Persons with intellectual disabilities (ID) often show challenging behaviour. We review distinct interventions that are applied to treat these challenging behaviours, and analyse intervention effects and moderating variables. Methods: A literature search was conducted using the databases "ERIC," "PsycINFO," "Web of Science" and…
