ABSTRACT
This final chapter considers three important questions: 1. What factors influence intervention success and how should these be characterized? 2. How can health behavior change be achieved on a widespread, global stage to tackle current and emergent health issues? 3. How can the science of behavior change develop more quickly? In relation to the first question, behavior change techniques are undoubtedly important and theory should also play a role, but other factors such as characteristics of the participants and interventionists, the intensity or duration of the intervention, the setting and characteristics of the behavior itself should not be overlooked. To achieve intervention success on a broad scale, including in low-income countries, we highlight the importance of scalability and sustainability. Finally, we propose better theories and techniques, reporting and measures, computer science, adaptive designs, more sophisticated statistics and consideration of biological and neurological influences can accelerate progress in the field.
