Hua, Youjia; Hinzman, Michelle; Yuan, Chengan; Balint Langel, Kinga – Exceptional Children, 2020
An emerging body of research suggests that incorporating randomization schemes in single-case research designs strengthens study internal validity and data evaluation. The purpose of this study was to test the utility and feasibility of a randomized alternating-treatment design in an investigation that compared the combined effects of vocabulary…

Osenk, Ivana; Johnson, Catherine; Wade, Tracey D. – School Mental Health, 2023
Perfectionism has adverse impacts on mental health and academic outcomes. We evaluated a 5-lesson classroom intervention for young adolescents delivered by teachers for impact on perfectionism, well-being, self-compassion, academic motivation and negative affect, at post-intervention and 3-month follow-up. Classes (N = 636 students, M[subscript…

Hagopian, Louis P. – Journal of Applied Behavior Analysis, 2020
Single-case experimental designs (SCEDs) have proven invaluable in research and practice because they are optimal for asking many experimental questions relevant to the analysis of behavior. The consecutive controlled case series (CCCS) is a type of study in which a SCED is employed in a series of consecutively encountered cases that undergo a…

de Jong, Valentijn M. T.; Moons, Karel G. M.; Riley, Richard D.; Tudur Smith, Catrin; Marson, Anthony G.; Eijkemans, Marinus J. C.; Debray, Thomas P. A. – Research Synthesis Methods, 2020
Many randomized trials evaluate an intervention effect on time-to-event outcomes. Individual participant data (IPD) from such trials can be obtained and combined in a so-called IPD meta-analysis (IPD-MA), to summarize the overall intervention effect. We performed a narrative literature review to provide an overview of methods for conducting an…

Reese, Elaine; Barrett-Young, Ashleigh; Gilkison, Laura; Carroll, Jane; Das, Shika; Riordan, Jessica; Schaughency, Elizabeth – Reading and Writing: An Interdisciplinary Journal, 2023
Tender Shoots is a randomized controlled trial (RCT) for parents aimed at improving preschool children's oral language skills relevant for later reading. Parents of 72 preschool children (M = 50 months) were randomly assigned to either a Rich Reading and Reminiscing (RRR) condition, a Strengthening Sound Sensitivity (SSS) condition, or an…

Alighieri, Cassandra; Bettens, Kim; Perry, Jamie; Hens, Greet; Roche, Nathalie; Van Lierde, Kristiane – International Journal of Language & Communication Disorders, 2023
Background: Compensatory cleft speech disorders can severely impact speech understandability and speech acceptability. Speech intervention is necessary to eliminate these disorders. There is, however, currently no consensus on the most effective speech therapy approach to eliminate the different subtypes of compensatory cleft speech disorders.…

Chun-Wei Huang; Linlin Li; Mingyu Feng – Society for Research on Educational Effectiveness, 2025
Background: An efficacy study based on a randomized controlled trial (RCT) was designed to evaluate the impact of ASSISTments on math learning among middle school students, including those from high-needs rural schools. Despite extensive recruitment efforts in 2021 (during the pandemic), only a few schools and their teachers agreed to participate,…

Chun-Wei Huang; Mingyu Feng; Linlin Li – WestEd, 2025
This is a technical report detailing the analytic methods used to assess the effects of a virtual professional learning community (vPLC)-enhanced ASSISTments intervention. The report uses a quasi-experimental design and partially nested regression model to account for clustering and reveals that while overall effects were positive but not…

Charlotte Z. Mann; Jiaying Wang; Adam Sales; Johann A. Gagnon-Bartsch – Grantee Submission, 2024
The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

Ledford, Jennifer R. – American Journal of Evaluation, 2018
Randomization of large number of participants to different treatment groups is often not a feasible or preferable way to answer questions of immediate interest to professional practice. Single case designs (SCDs) are a class of research designs that are experimental in nature but require only a few participants, all of whom receive the…

Jensen de López, Kristine M.; Kraljevic, Jelena Kuvac; Struntze, Emilie L. Bang – International Journal of Language & Communication Disorders, 2022
Background: It is widely acknowledged that children with developmental language disorder (DLD) predominantly have difficulties in the areas of grammar and vocabulary, with preserved pragmatic skills. Consequently, few studies focus on the pragmatic skills of children with DLD, and there is a distinct lack of studies examining the effectiveness of…

Pedder, Hugo; Boucher, Martin; Dias, Sofia; Bennetts, Margherita; Welton, Nicky J. – Research Synthesis Methods, 2020
Time-course model-based network meta-analysis (MBNMA) has been proposed as a framework to combine treatment comparisons from a network of randomized controlled trials reporting outcomes at multiple time-points. This can explain heterogeneity/inconsistency that arises by pooling studies with different follow-up times and allow inclusion of studies…

Armijo-Olivo, Susan; Craig, Rodger; Campbell, Sandy – Research Synthesis Methods, 2020
Background: Evidence from new health technologies is growing, along with demands for evidence to inform policy decisions, creating challenges in completing health technology assessments (HTAs)/systematic reviews (SRs) in a timely manner. Software can decrease the time and burden by automating the process, but evidence validating such software is…

Behavioral and social sciences randomized controlled trials (BSSTs) have a significant role in life sciences. Choosing an appropriate control or comparator group for BSSTs is critical, to provide true intervention effects. The objective of this study was to determine the types of control groups used in BSSTs, and the rationale provided to justify…
