Description
Igor Marchetti and co-authors ask a flipped question about eating disorder signs in teenage girls. They do not ask what raises the risk on average, but what must be missing for the signs to appear at all. Their 2025 study applies necessary condition analysis, a method built for that flip. Low self-esteem is the candidate condition.
Eighty-four girls, about sixteen on average, were followed for twelve months. Three outcomes were tested: drive for thinness, body dissatisfaction, and bulimic behaviors. Low self-esteem did emerge as a necessary condition for the first two, with modest effect sizes. The authors present the work as preliminary, and frame the method as a sharper lens than averages for spotting true prerequisites.
