Diffusion of innovations theory can be used to understand how to prevent or slow the spread of harmful behaviors, such as e-cigarette use in adolescent social networks. This study explores how different network intervention strategies could impact diffusion dynamics through network simulations based on observed social norms and e-cigarette use…

Background: For approximately one in five children who have social, emotional, and behavioral (SEB) challenges, accessible evidence-based prevention practices (EBPPs) are critical. In the USA, schools are the primary setting for children's SEB service delivery. Still, EBPPs are rarely adopted and implemented by front-line educators (e.g.,…

Behaviour change communication (BCC) remains a central component of the interventions used in the fight against malaria in Ghana. However, there is limited evidence of its effectiveness. This study evaluated the effects of BCC strategies on knowledge (symptoms, causes and prevention) and overall knowledge of malaria among Ghanaian women aged…

We estimate the effect of universal free school meal access through the Community Eligibility Program (CEP) on child body mass index (BMI). Through the CEP, schools with high percentages of students qualified for free or reduced-priced meals can offer free breakfast and lunch to all students. With administrative data from a large school district…

Participants: Participants were college students who turned 21 years old between January 21, 2016 and September 27, 2017. A total of 1,064 students completed the posttest: 737 from…

We estimate the effect of universal free school meal access through the Community Eligibility Program (CEP) on child BMI. Through the CEP, schools with high percentages of students qualified for free or reduced-priced meals can offer free breakfast and lunch to all students. With administrative data from a large school district in Georgia, we use…

Background: The prevalence of overweight and obesity in childhood makes intervention imperative, and schools provide a privileged setting in which to undertake this work. Teachers have the potential to influence children's eating behaviour through nutrition education and by acting as positive role models. We conducted a case-control study in 14…

Objective: Evaluate effectiveness of a university-wide social norms marketing campaign to reduce high-risk drinking and its consequences among students at MSU.

Positive Behavioral Interventions and Supports (PBIS) has been shown to be a promising approach for improving a range of behavioral health and academic outcomes for youth. This study leveraged data from the scale-up of PBIS and a randomized controlled trial, both conducted in Maryland, to estimate the dollars saved per 100 students as a result of…

Background: There is little understanding of men's weight loss outcomes and behaviors in self-directed contexts, such as digital commercial mobile weight management programs. This is an especially pressing question given that men often express disinterest in weight management programs and it is unknown how that manifests in self-directed…

Completely switching from cigarette smoking to electronic nicotine delivery systems (ENDS) reduces exposure to toxic substances. Yet, many smokers believe that ENDS are at least as harmful as smoking, making them less likely to switch from cigarettes to ENDS. Effectively communicating reduced-exposure information is critical, but such messages…
