In the parametric strategy, the researcher compares treatments that differ in the quantity or intensity of a particular treatment component, while keeping all other components constant. This strategy allows researchers to identify which specific component(s) of a treatment are most effective or necessary for producing the desired outcomes. The dismantling strategy involves systematically removing components from a treatment package to identify which components are essential for producing the desired outcomes. The treatment package strategy involves comparing a complete treatment package to a control group or alternative treatment package. The additive strategy involves combining multiple treatment components to determine if the combined treatment is more effective than any individual component on its own.
