Randomized Controlled Trial Multicenter Study
One-year follow-up of a coach-delivered dating violence prevention program: a cluster randomized controlled trial.
Perpetration of physical, sexual, and psychological abuse is prevalent in adolescent relationships. One strategy for reducing such violence is to increase the likelihood that youth will intervene when they see peers engaging in disrespectful and abusive behaviors. ⋯ This school athletics-based dating violence prevention program is a promising approach to reduce perpetration and negative bystander behaviors that condone dating violence among male athletes.

Randomized Controlled Trial
A participatory physical activity intervention in preschools: a cluster randomized controlled trial.
Previous studies on physical activity interventions in preschools have reported limited effectiveness. Participatory community-based approaches hold promise for increasing intervention effectiveness and involving parents as key stakeholders in a sustainable way. ⋯ A participatory preschool intervention focusing on parents as agents of behavioral change may be able to promote PA and reduce sedentary behavior in preschoolers. These benefits may go beyond the effects of existing nonparticipatory interventions.

Use of data generated through social media for health studies is gradually increasing. Twitter is a short-text message system developed 6 years ago, now with more than 100 million users generating over 300 million Tweets every day. Twitter may be used to gain real-world insights to promote healthy behaviors. ⋯ The approach includes five steps: (1) selecting keywords to gather an initial set of Tweets to analyze; (2) importing data; (3) preparing data; (4) analyzing data (topic, sentiment, and ecologic context); and (5) interpreting data. The steps are implemented using tools that are publically available and free of charge and designed for use by researchers with limited programming skills. Content mining of Tweets can contribute to addressing challenges in health behavior research.

Evidence is mixed on the effects of graduated driver licensing (GDL) on motor vehicle crashes involving drivers aged 18 years. ⋯ GDL led to expected declines in crash rates for drivers aged 16 and 17 years. However, the findings suggest that when GDL applies only to novice drivers aged <18 years, rather than to all novice drivers, crash rates among drivers aged 18 years may increase. In order to potentially extend the safety benefits of GDL, the age at which GDL for new drivers should be applied requires further attention.

Randomized Controlled Trial
Physical activity loyalty cards for behavior change: a quasi-experimental study.
Financial incentives have been advocated by the UK and U.S. governments to encourage adoption of healthy lifestyles. However, evidence to support the use of incentives for changing physical activity (PA) behavior is sparse. ⋯ Financial incentives did not encourage participants to undertake more PA than self-monitoring PA. This study contributes to the evidence base and has important implications for increasing participation in physical activity and fostering links with the business sector.
