In this response, we first show that Simpson's proposed analysis answers a different and less interesting question than ours. We then justify the choice of prior for our Bayes factors calculations, but we also demonstrate that the substantive conclusions of our article are not substantially affected by varying this choice.

Objective: To evaluate the effectiveness of interventions targeting alcohol consumption, drug use and smoking for college/university students.Participants: College/University students. Methods: Studies were eligible if: (1)included students attending universities/colleges; (2)implemented in a university/college setting; (3)aimed to improve at…

Purpose: The aim of this study was to test the hypothesis that stretch-and-flow voice therapy (SnF) is noninferior to resonant voice therapy (RVT) for speakers with muscle tension dysphonia. Method: Participants with primary muscle tension dysphonia were randomly assigned to 1 of 2 treatment groups. Participants received 6 sessions of either SnF…

The objective was to evaluate the effectiveness of a self-management patient education programme for fibromyalgia syndrome (FMS) as compared with usual care education in inpatient rehabilitation. In a multicentre cluster-randomized controlled trial, 583 inpatients in 3 rehabilitation centres received an advanced self-management patient education…

Objective: To build the evidence base for first aid education by testing the hypothesis that learners will be more confident and willing to act in an emergency if their first aid education has attempted to break down perceived barriers to helping. Design: Additional activities were appended to and delivered alongside a control curriculum…

Purpose: The purpose of this randomized controlled trial was to examine the effects of a multitiered system of language support (MTSLS) on kindergarteners' narrative retelling, personal stories, writing, and expository language. Method: Participants were 686 kindergarten students from four school districts in the United States. Twenty-eight…

Although there is increasing acceptance that personalization improves learning outcomes, there is still limited experimental evidence supporting this claim. The aim of this study was to implement and evaluate the effectiveness of an adaptive recommendation system for Singapore primary and secondary education. The system leverages users trace data…

Background: Efficacy trials in education often possess a motivating theory of change: how and why should the desired improvement in outcomes occur as a consequence of the intervention? In scenarios with repeated measurements, certain subgroups may be more or less likely to manifest a treatment effect; the theory of change (TOC) provides guidance…

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.…

Objective: College students with attention deficit/hyperactivity disorder (ADHD) are at increased risk for numerous educational and psychosocial difficulties. This study reports findings from a large, multisite randomized controlled trial examining the efficacy of a treatment for this population, known as ACCESS -- Accessing Campus Connections and…

Aim: To describe the development of an intervention-specific fidelity measure and its utilization and to determine whether the newly developed Sitting Together and Reaching to Play (START-Play) intervention was implemented as intended. Also, to quantify differences between START-Play and usual early intervention (uEI) services. Method: A fidelity…

A solid understanding of fractions is the cornerstone for acquiring proficiency with rational numbers and paves the way for learning advanced mathematical concepts, such as algebra. Fraction difficulties limit not only students' educational and vocational opportunities but also their ability to solve everyday problems. Students who exit 6th grade…

Medical research is held as a field for education to emulate. Education researchers have been urged to adopt randomized controlled trials, a more "scientific" research method believed to have resulted in the advances in medicine. But a much more important lesson education needs to borrow from medicine has been ignored. That is the study…

This paper reviews the use of multiple trials, defined as multiple sites or multiple arms in a single evaluation and replications, in evaluating social programs. After defining key terms, the paper discusses the rationales for conducting multiple trials, which include increasing sample size to increase statistical power; identifying the most…

The number of trials aimed at evaluating treatments for autism spectrum disorder has been increasing progressively. However, it is not clear which outcome measures should be used to assess their efficacy, especially for treatments which target core symptoms. The present review aimed to provide a comprehensive overview regarding the outcome…
