The edwards personal preference inventory (eppi) tries to limit the social desirability response style by using forced-choice item matching.
A social desirability response style is when someone is doing a survey and tries to answer it in a way they think the viewer/grade would like to see vs. how they actually feel. When they provide questions using forced-choice item matching it takes out a lot of the biased answers by making the person describe their reasoning for choices a bit more.
