Quizplus · Accepted Answer

The diathesis-stress model proposes that a person can inherit a predisposition (diathesis) towards a mental disorder, but that the disorder will only develop if triggered by significant life stressors (stress).

Option A is incorrect because mental disorders may not always develop even under significant stress. Option B is incorrect because not everyone who inherits a diathesis will develop the disorder. Option C is incorrect because stressful life events can exacerbate or diminish the expression of genetic or inherited tendencies.
