Evaluating the impact of complex whole-school interventions (CWSIs) is challenging. However, what evidence there is suggests that school leadership and other elements of whole-school contexts are important for pupils' attainment (Leithwood et al., 2006), suggesting that interventions aimed at changing these have significant potential to improve…

Introduction: Mentors can help college graduates with visual impairments (that is, those with blindness or low vision) prepare for and seek employment in their chosen fields by serving as role models and sharing their experiences with mentees. Identifying mentoring activities and discussions most valued by mentees with visual impairments will…

Recommendations for the prevention of childhood obesity encourage providers to counsel parents and their children on healthy diet and activity behaviors. This study evaluated the feasibility of a theory-based, tailored communication intervention for obesity prevention ("Team Up for Health") delivered during a well-child visit. A…

Young children are surrounded by ubiquitous environmental print (e.g. signs, product labels) on a daily basis in their homes and communities. Parent-child interactions with environmental print has the potential to foster emergent literacy. A randomised controlled pre-posttest study was conducted to examine the effects of a parent-child…

Background. Despite the emergence of new hepatitis C virus (HCV) antiviral medications, many people with chronic HCV know little about their disease, are at risk for transmitting HCV to others, and/or are not considered good treatment candidates. Self-management interventions can educate HCV-infected persons, improve their quality of life, and…

There's a strong case for making social and emotional learning (SEL) skills and competencies a central feature of elementary school. Children who master SEL skills get along better with others, do better in school, and have more successful careers and better mental and physical health as adults.

Background/Context: Teacher collaboration, instructional practices, and efficacy are linked in various ways in the literature. For example, in schools where teachers reported greater use of differentiated instruction, team collaboration and culture were reportedly higher (Smit & Humpert, 2012).

Executive functions (EFs) develop rapidly in preschoolers and lay an important foundation for school readiness. One potential method of supporting EF development is through mindfulness-based interventions (MBIs). Whereas studies with older children and adults have supported this approach, research with young children has been more limited. In the…

Background and objectives: Although randomized controlled trials (RCTs) have been performed to alleviate loneliness among older people, little is known about how they have been implemented, or whether they are effective in real life. Our RCT-based model, "Circle of Friends" (CoF) proved to be effective in improving the wellbeing, health…

The goal of this study is to better understand how methods for estimating treatment effects of latent groups operate. In particular, the authors identify where violations of assumptions can lead to biased estimates, and explore how covariates can be critical in the estimation process. For each set of approaches, the authors first review the…

Beginning in 2002, researchers developed, implemented, and evaluated the efficacy of an English reading intervention for first-grade English learners using multiple randomized control trials (RCTs). As a result of this efficacy work, researchers successfully competed for an IES Goal 4 effectiveness study using the same intervention. Unlike the…
