Purpose

To showcase and critique a range of different approaches to designing interventions to change nutrition, physical activity, sedentary behaviors and sleep behaviors.

Rationale

Investing time in quality design of behavior change interventions is critical to intervention success. There are numerous theoretical approaches and frameworks to assist in evidence and theory-informed intervention design. Further there are specific study designs and new approaches that can test intervention components early in the testing process to reduce research waste that can result from testing complex interventions.   

Objectives

·         Inform researchers about different approaches/innovative methods to design and test interventions

·         Present examples of the design methods and early results

·         Summarize the benefits of collaboration and use of innovative methods to design and test health behavior interventions

Summary

This symposium will begin by discussing why there is a need for advanced intervention design and introduce a range of tools and methods available. Case studies of how to apply different approaches to design interventions to change nutrition, physical activity, sedentary behaviors and sleep behaviors will be presented. The discussant will summarise the program of research and facilitate discussion about the benefits and limitations of intervention design approaches.

Discussant (5mins) – Summary recap of the presentations (Heather Wasser)

Panel questions and guided discussion (15mins)

Interaction

Slido polls and questions will be used throughout the symposium. Pre-conference tweets will seek other examples of intervention design and questions to pose to the panel.
