TL;DR: In this paper, the authors evaluated whether a structured Internet behavioral weight loss program produces greater initial weight loss and changes in waist circumference than a weight loss education Web site and found that participants who were given a structured behavioral treatment program with weekly contact and individualized feedback had better weight loss compared with those given links to educational Web sites.

TL;DR: Results of structural equation modeling indicated a good fit of the social cognitive model to the data, and self-efficacy had the greatest total effect on physical activity, mediated largely by self-regulation, which directly predicted physical activity.

TL;DR: Popular and well-liked members of a community who systematically endorse and recommend risk-reduction behaviour can influence the sexual-risk practices of others in their social networks and bring about population-level changes in risk behaviour.

TL;DR: A social-cognitive model of physical activity was tested, using structural equation analysis of data from 999 adults recruited from 14 southwestern Virginia churches participating in the baseline phase of a health promotion study, and explained 46% of the variance in physical activity among the diverse group of adults.

TL;DR: Interventions effective at garnering family support, increasing nutrition related self-efficacy, and overcoming negative outcome expectations should be more successful at helping adults enact the self-regulatory behaviors essential to buying and eating healthier foods.
