Answer:
Diathesis - stress model
Step-by-step explanation:
Diathesis - stress model is a theory that tries to explain how the interaction of genetic factors and environmental stress or triggers can develop into a disorder. In other words, it is a theory that attempts to throw light on how certain mental disorders like Schizophrenia and anxiety could be influenced or caused by the interactions between genetic predisposition (diathesis) and environmental influences (stress).
As it relates to diathesis, an individual's genetic predisposition can make them vulnerable to succumb to a certain disorder if they encounter certain stressors. However, as it relates to stress, an individual who is vulnerable to depression will not become depressed, until they exposed to the depressive stressor.
