A multiple independent variable design is the best choice to test for the existence of interactions. This design allows for manipulating and measuring the effects of more than one independent variable on a dependent variable, allowing the researcher to identify possible interactions between the variables. A multiple dependent variable design and a multiple confounding variable design may be useful in other research contexts but are not specifically designed to test for interactions.
