The diathesisstress model is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability and a stress caused by life experiences.

Also, who gave diathesis stress model? The term has been used in a psychiatric context since the 1800s.

In this regard, what is the diathesis stress model of depression?

The diathesisstress model talks about the relationship between potential causes of depression and the amount that people may be sensitive or vulnerable to react to those causes. The diathesisstress model believes that people have different levels of sensitivity for developing depression.

How does the biological approach explain schizophrenia?

Evidence suggests that the closer the biological relationship, the greater the risk of developing schizophrenia. Gottesman (1991) has found that schizophrenia is more common in the biological relatives of a schizophrenic, and that the closer the degree of genetic relatedness, the greater the risk.
