Recurrent Individual Treatment Assignment: A Treatment Policy Approach to Account for Heterogeneous Treatment Effects
Peer reviewed Peer reviewed
Direct linkDirect link
Ilja Cornelisz; Chris van Klaveren – npj Science of Learning, 2022
Longitudinal randomized controlled trials generally assign individuals randomly to interventions at baseline and then evaluate how differential average treatment effects evolve over time. This study shows that longitudinal settings could benefit from "Recurrent Individual Treatment Assignment" ("RITA") instead, particularly in…

Norman Porticella; Julie S. Cannon; Chung Li Wu; Stuart G. Ferguson; James F. Thrasher; Emily E. Hackworth; Jeff Niederdeppe – Health Education & Behavior, 2024
Underrepresentation of historically marginalized populations in clinical trials continues to threaten the validity of health intervention research. Evidence supports the merits of intercept and other proactive forms of recruitment for achieving more equitable representation. However, researchers also report lower retention and adherence to…

Effectiveness and Cost-Effectiveness of High-Intensity versus Low-Intensity Speech Intervention in Children with a Cleft Palate: Protocol for a Randomized Controlled Trial
Peer reviewed Peer reviewed

Fien Allemeersch; Kristiane Van Lierde; Nick Verhaeghe; Kim Bettens; Tara Mouton; Greet Hens; Cassandra Alighieri – International Journal of Language & Communication Disorders, 2025
Background: In children with a cleft palate with or without a cleft lip (CP±L), some evidence exists for superior results of high-intensity speech intervention (HISI) compared with low-intensity speech intervention (LISI) on speech and health-related quality of life (HRQoL). However, the existing research often involves small sample sizes.…

Power Analysis for Moderator Effects in Longitudinal Cluster Randomized Designs
Peer reviewed Peer reviewed
Direct linkDirect link
Li, Wei; Konstantopoulos, Spyros – Educational and Psychological Measurement, 2023
Cluster randomized control trials often incorporate a longitudinal component where, for example, students are followed over time and student outcomes are measured repeatedly. Besides examining how intervention effects induce changes in outcomes, researchers are sometimes also interested in exploring whether intervention effects on outcomes are…

Musci, Rashelle J.; Kush, Joseph M.; Masyn, Katherine E.; Esmaeili, Masoumeh Amin; Susukida, Ryoko; Goulter, Natalie; McMahon, Robert; Eddy, J. Mark; Ialongo, Nicholas S.; Tolan, Patrick; Godwin, Jennifer; Bierman, Karen L.; Bierman, Karen L.; Coie, John D.; Crowley, D. Max; Dodge, Kenneth A.; Greenberg, Mark T.; Lochman, John E.; McMahon, Robert J.; Pinderhughes, Ellen E.; Wilcox, Holly C. – Prevention Science, 2023
Psychotic-like experiences (PLEs) are common throughout childhood, and the presence of these experiences is a significant risk factor for poor mental health later in development. Given the association of PLEs with a broad number of mental health diagnoses, these experiences serve as an important malleable target for early preventive interventions.…

A Longitudinal RCT of P-ESDM with and without Parental Mindfulness Based Stress Reduction: Impact on Child Outcomes
Peer reviewed Peer reviewed

Weitlauf, Amy S.; Broderick, Neill; Alacia Stainbrook, J.; Slaughter, James C.; Taylor, Julie Lounds; Herrington, Catherine G.; Nicholson, Amy G.; Santulli, Madeline; Dorris, Kristin; Garrett, LaTamara Jackson; Hopton, Michelle; Kinsman, Amy; Morton, Mary; Vogel, Ashley; Dykens, Elisabeth M.; Pablo Juárez, A.; Warren, Zachary E. – Journal of Autism and Developmental Disorders, 2022
This randomized controlled trial (NCT03889821) examined Mindfulness Based Stress Reduction (MBSR) in conjunction with the Parent-implemented Early Start Denver Model (P-ESDM). A previous report described improved metrics of parental distress (Weitlauf et al. in Pediatrics 145(Supplement 1):S81-S92, 2020). This manuscript examines child outcomes.…

Leveraging Item Parameter Drift to Assess Transfer Effects in Vocabulary Learning. EdWorkingPaper No. 23-868
PDF on ERIC Download full text
Joshua B. Gilbert; James S. Kim; Luke W. Miratrix – Annenberg Institute for School Reform at Brown University, 2024
Longitudinal models of individual growth typically emphasize between-person predictors of change but ignore how growth may vary "within" persons because each person contributes only one point at each time to the model. In contrast, modeling growth with multi-item assessments allows evaluation of how relative item performance may shift…

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.…
