RAND Europe evaluated the implementation of a technology-based intervention that made use of the Microsoft Immersive Reader (IR) in UK classrooms for eight- and nine-year-old pupils. This is the first evaluation of this intervention that uses a randomised control trial (RCT) design, following promising findings related to the use of IR from a…

Randomized controlled trials (RCTs) are a long-standing and important design for conducting rigorous tests of the effectiveness of health interventions. However, many questions have been raised about the external validity of RCTs, their utility in explicating mechanisms of intervention and participants' intervention experiences, and their…

Objective: To assess evidence of the effectiveness of school-based education programs for the prevention of child sexual abuse (CSA). The programs deliver information about CSA and strategies to help children avoid it and encourage help seeking. Methods: Systematic review including meta-analysis of randomized controlled trials (RCTs), cluster…

Estimating treatment effects for subgroups defined by posttreatment behavior (i.e., estimating causal effects in a principal stratification framework) can be technically challenging and heavily reliant on strong assumptions. We investigate an alternative path: using bounds to identify ranges of possible effects that are consistent with the data.…

The prevention science approach to emotional/behavioral disorders (EBD) focuses on early intervention targeting risk and resilience factors (e.g., early problem behaviors, teacher-child interactions, classroom climate). The current study investigates the effectiveness of BEST in CLASS, a classroom-based indicated preventive intervention targeting…

Background: People with dementia and family carers often experience difficulties communicating together. These difficulties are considered to contribute significantly to the depression, anxiety and negative feelings such as guilt often reported by dementia family carers. Aims: To develop and contribute to the theory and evidence base for…

Policymakers have invested significant resources in financial education to improve financial literacy of the poor, reduce bad financial decision-making, and increase take-up of financial services and products. Yet, there is limited evidence on the effectiveness of such interventions, especially in developing countries. This paper provides evidence…

This document presents the testimony of MDRC's Alex Mayer, the Deputy Director for Postsecondary Education at MDRC. The three points that Alex Mayer emphasizes in this testimony before the California State Assembly Higher Education Committee and the Budget Subcommittee on Education Finance on integrating postsecondary education interventions to…

A meta-analysis of randomized controlled trials (RCTs) has recently showed that theory-based interventions designed to promote physical activity (PA) significantly increased PA behavior. The objective of the present study was to investigate the moderators of the efficacy of these theory-based interventions. Seventy-seven RCTs evaluating…

Background: Insufficient sleep among students is a major school health problem. School-based sleep education programs tailored to reach large number of students may be one of the solutions. A systematic review and meta-analysis was conducted to summarize the programs' effectiveness and current status. Methods: Electronic databases were searched up…

Children with a diagnosis of autism are more likely to experience anxiety than their typically developing peers. Research suggests that Cognitive Behavioural Therapy (CBT) could offer a way to help children with autism manage their anxiety but most evidence is based on clinical trials. This study investigated a school-based CBT programme using a…

As the first major effort to use a behavioral economics lens to examine human services programs that serve poor and vulnerable families in the United States, the Behavioral Interventions to Advance Self-Sufficiency (BIAS) project demonstrated the value of applying behavioral insights to improve the efficacy of human services programs. The BIAS…

The benefits of mindfulness for a variety of clinical and nonclinical populations are well established and there is growing interest in the potential of mindfulness in higher education. This article reports on the results from a randomized wait-list controlled study of Mindfulness-Based Coping With University Life (MBCUL), an adaption of…

Teacher professional development and in-class mentors were used to support structured inquiry with math manipulatives. Twenty-four primary schools (n = 6,628 students) were randomly assigned to treatment and control groups as an experimental field trial to examine the effectiveness of this instructional approach in a scaled-up application in…

Increasingly, researchers are interested in questions regarding treatment-effect variation across partially or fully latent subgroups defined not by pretreatment characteristics but by postrandomization actions. One promising approach to address such questions is principal stratification. Under this framework, a researcher defines endogenous…
