Intervention Optimization: A Paradigm Shift and Its Potential Implications for Clinical Psychology

Area of Science:

• Psychological intervention science
• Behavioral science
• Implementation science

Background:

• Classical treatment package research limits understanding of effective psychological interventions.
• A need exists for a research paradigm that optimizes interventions for sustained societal impact.

Purpose of the Study:

• Introduce the multiphase optimization strategy (MOST) as an alternative to classical research paradigms.
• Provide an overview of MOST, its experimental designs, and application in implementation science.
• Highlight the potential of MOST to accelerate progress in psychological intervention science.

Main Methods:

• MOST integrates principles from behavioral science, engineering, economics, and decision science.
• Utilizes various experimental designs for intervention optimization.
• Employs experimental results to select intervention components for optimized outcomes.

Main Results:

• MOST enables strategic balancing of intervention effectiveness, affordability, scalability, and efficiency.
• Facilitates the selection of effective intervention components.
• Demonstrates feasibility and potential for advancing psychological intervention research.

Conclusions:

• MOST represents a feasible and promising new research paradigm for psychological interventions.
• Adopting MOST can hasten the development and impact of psychological interventions.
• This approach optimizes interventions for greater effectiveness and societal benefit.
