Human-centered design methods to achieve preparation phase goals in the multiphase optimization strategy framework

Abstract

1. <i>What is already known about the topic?</i> Optimizing behavioral interventions to balance effectiveness with affordability, scalability, and efficiency requires a significant investment in intervention development.2. <i>What does this paper add?</i> This paper provides a structured approach to integrating human-centered design principles into the <i>Preparation</i> phase of the multiphase optimization strategy (MOST).3. <i>What are the implications for practice, research, or policy?</i> The proposed synthesized model provides a framework for rigorous and efficient intervention development research in the <i>Preparation</i> phase of MOST that will ensure the success of intervention optimization and contribute to improving public health impact of mental health and substance use interventions.
