Randomized Controlled TrialEffects of 12-month exercise on health-related quality of life: a randomized controlled trial.
We investigated exercise effects on health-related quality of life (HRQOL) and exercise self-efficacy, and tested effect modification by baseline body mass index (BMI) and gender. ⋯ Three hundred and sixty minutes per week of exercise, recommended for weight maintenance, did not have negative effects on exercise self-efficacy or HRQOL. This level of exercise may increase HRQOL among overweight men.

Randomized Controlled TrialRandomized controlled trial of the Physical Activity Leaders (PALs) program for adolescent boys from disadvantaged secondary schools.
The aim of this study was to evaluate the efficacy and feasibility of the Physical Activity Leaders (PALs) program. PALs is an obesity prevention program for low-active adolescent boys from disadvantaged schools. ⋯ The PALs program was a feasible and efficacious approach to induce healthy weight loss in adolescent boys from disadvantaged secondary schools.

Randomized Controlled TrialThe impact of individually-tailored lifestyle advice in the colorectal cancer screening context: a randomised pilot study in North-West London.
The screening context may provide a "teachable moment" for promoting health behaviours. The present study examined the impact on diet, alcohol and physical activity of providing individually-tailored advice in the context of flexible sigmoidoscopy (FS) screening. ⋯ Tailored advice given in the context of cancer screening may provide an opportunity to improve dietary behaviours. Further research is needed to determine whether screening provides a unique "teachable moment" or if similar effects can be achieved in other health settings.

Randomized Controlled TrialResults of a multi-media multiple behavior obesity prevention program for adolescents.
This study reports on effectiveness trial outcomes of Health in Motion, a computer tailored multiple behavior intervention for adolescents. ⋯ Health in Motion is an innovative, multiple behavior obesity prevention intervention relevant for all adolescents that relies solely on interactive technology to deliver tailored feedback. The outcomes of the effectiveness trial demonstrate both an ability to initiate behavior change across multiple energy balance behaviors simultaneously and feasibility for ease of dissemination.

Randomized Controlled TrialOne-year follow-up evaluation of the Project Towards No Drug Abuse (TND) dissemination trial.
The aims of this trial, conducted 2004-2008, were to examine (1) the effectiveness of Project Towards No Drug Abuse (TND) at the one-year follow-up when implemented on a large scale; and (2) the relative effectiveness of two training approaches for program implementers. ⋯ Positive outcomes may be achieved by trained teachers when they implement Project TND in real-world high school environments; however, program effects are likely to be weaker than those achieved in efficacy trials. Training workshops may be adequate to build capacity for successful program implementation.
