title: Evaluation framework for translational research: case study of Australia's get healthy information and coaching service(R).
abstract: The Get Healthy Information and Coaching Service® (GHS), a free government-funded telephone-delivered information and coaching service was launched in February 2009 by the Australian New South Wales state government. It represents the translation of research evidence applied in the real world (T4 or Phase 4 translation), aimed at addressing the modifiable risk factors associated with the overweight and obesity. In controlled settings, it has been established that telephone-based lifestyle counseling programs are efficacious in reducing anthropometric and behavioral risk factors. This article presents the GHS case study as a population-wide intervention and describes the quasi-experimental evaluation framework used to evaluate both the process (statewide implementation) and impact (effectiveness) of the GHS in a real-world environment. It details the data collection, measures, and statistical analysis required in assessing the process of implementation-reach and recruitment, marketing and promotion, service satisfaction, intervention fidelity, and GHS setting up and operations costs-and in assessing the impact of GHS-increasing physical activity, improving dietary practices, and reducing body weight and waist circumference. The comprehensive evaluation framework designed for the GHS provides a method for building effectiveness evidence of a rare translation of efficacy trial evidence into population-wide practice.
