Deborah M. Caldwell; Jennifer C. Palmer; Katie E. Webster; Sarah R. Davies; Hugo Hughes; Joseph Rona; Rachel Churchill; Sarah E. Hetrick; Nicky J. Welton – Prevention Science, 2025
Many randomized controlled trials have investigated the role of school-based prevention interventions to reduce symptoms of anxiety and depression in young people. Systematic reviews have subsequently demonstrated a small, beneficial effect of these interventions when compared to a combined control group including usual care, no intervention, or…

Phillippo, David M.; Dias, Sofia; Ades, A. E.; Welton, Nicky J. – Research Synthesis Methods, 2020
Indirect comparisons are used to obtain estimates of relative effectiveness between two treatments that have not been compared in the same randomized controlled trial, but have instead been compared against a common comparator in separate trials. Standard indirect comparisons use only aggregate data, under the assumption that there are no…

Piepho, Hans-Peter; Madden, Laurence V. – Research Synthesis Methods, 2022
Network meta-analysis is a popular method to synthesize the information obtained in a systematic review of studies (e.g., randomized clinical trials) involving subsets of multiple treatments of interest. The dominant method of analysis employs within-study information on treatment contrasts and integrates this over a network of studies. One…

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…

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…

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.…

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…

Saluja, Ronak; Cheng, Sierra; delos Santos, Keemo Althea; Chan, Kelvin K. W. – Research Synthesis Methods, 2019
Objective: Various statistical methods have been developed to estimate hazard ratios (HRs) from published Kaplan-Meier (KM) curves for the purpose of performing meta-analyses. The objective of this study was to determine the reliability, accuracy, and precision of four commonly used methods by Guyot, Williamson, Parmar, and Hoyle and Henley.…

Iadarola, Suzannah; Levato, Lynne; Harrison, Bryan; Smith, Tristram; Lecavalier, Luc; Johnson, Cynthia; Swiezy, Naomi; Bearss, Karen; Scahill, Lawrence – Journal of Autism and Developmental Disorders, 2018
We report on parent outcomes from a randomized clinical trial of parent training (PT) versus psychoeducation (PEP) in 180 children with autism spectrum disorder (ASD) and disruptive behavior. We compare the impact of PT and PEP on parent outcomes: Parenting Stress Index (PSI), Parent Sense of Competence (PSOC), and Caregiver Strain Questionnaire…

Meerschman, Iris; Van Lierde, Kristiane; Van Puyvelde, Caro; Bostyn, Astrid; Claeys, Sofie; D'haeseleer, Evelien – International Journal of Language & Communication Disorders, 2018
Background: In contrast with most medical and pharmaceutical therapies, the optimal dosage for voice therapy or training is unknown. Aims: The aim of this study was to compare the effect of a short-term intensive voice training (IVT) with a longer-term traditional voice training (TVT) on the vocal quality and vocal capacities of vocally healthy…

Matthews, Nicole L.; Orr, Beatriz C.; Warriner, Katrina; DeCarlo, Mary; Sorensen, Mia; Laflin, Jessica; Smith, Christopher J. – Journal of Autism and Developmental Disorders, 2018
This study compared immediate and 4-month outcomes among adolescents with autism spectrum disorder randomly assigned to the PEERS curriculum (n = 10), a peer mediated PEERS curriculum (n = 12), or a delayed treatment control group (n = 12). Findings suggest a modest advantage in social skills knowledge and social functioning for participants in…

Schwindt, Rhonda; Hudmon, Karen Suchanek; Knisely, Mitchell; Davis, Lorie; Pike, Caitlin – Journal of Drug Education, 2017
Persons with mental illness smoke at rates two to four times higher than do persons without mental illness and comprise 30.9% of the U.S. tobacco market. Given the prevalence of mental illness and the known detrimental effects of tobacco, concerted efforts are needed to promote the use of evidence-based treatment options. We conducted a systematic…
