Targeting preventive interventions: enhancing risk estimates through theory

Area of Science:

• Preventive medicine
• Epidemiology
• Intervention science

Background:

• Targeted preventive interventions require robust theoretical and epidemiological foundations.
• Mediational screening procedures are crucial for effective intervention design.
• Understanding disorder etiology and prospectively confirmed risk factors is essential.

Purpose of the Study:

• To outline the necessary components for incorporating mediational screening in targeted preventive interventions.
• To discuss the benefits of increased base rates and enhanced evaluation power through targeted selection.
• To highlight potential risks, including iatrogenic effects and impacts of population homogeneity.

Main Methods:

• Review of theoretical and epidemiological requirements for mediational screening.
• Analysis of targeting strategies using indicated and selective criteria.
• Consideration of potential negative consequences of focused targeting.

Main Results:

• Mediational screening enhances intervention power by increasing the base rate of disorders in the target population.
• Combined indicated and selective targeting can improve the detection of at-risk individuals.
• Overly focused targeting may lead to iatrogenic effects and reduced effectiveness in homogeneous populations.

Conclusions:

• Effective mediational screening necessitates a strong theoretical and epidemiological knowledge base.
• Strategic targeting enhances intervention efficacy but requires careful consideration of potential adverse effects.
• Balancing targeting precision with population characteristics is key to maximizing preventive intervention success.
