Diathesis-stress model refers also to the proposal that people are born with a predisposition (or "diathesis") that places them at risk for developing a psychological disorder if exposed to certain extremely stressful life experiences. Moreover, it refers to hypothesis that both an inherited tendency/ vulnerability and specific stressful conditions are required to produce a disorder.
