A related view, the diathesis-stress model, posits that mental disorders result from genetic dispositions and environmental stressors, combining to cause patterns of distress or dysfunction. [19] The model is one way to explain why some individuals are more vulnerable to mental disorders than others.
The diathesis-stress model, also known as the vulnerability–stress model, is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and stress caused by life experiences.
The concept of Environmental Sensitivity integrates multiple theories on how people respond to negative and positive experiences. These include the frameworks of Diathesis-stress model [4] and Vantage Sensitivity, [5] as well as the three leading theories on more general sensitivity: Differential Susceptibility, [6] [7] Biological Sensitivity to Context, [8] and Sensory processing sensitivity ...

Both models suggest that people's development and emotional affect are differentially affected by experiences or qualities of the environment. Where the ...
[5] [37] The diathesis–stress model specifies that depression results when a preexisting vulnerability, or diathesis, is activated by stressful life events.

The investigators suggested that in utero insults may specifically stress those with a schizophrenia diathesis, supporting a "diathesis-stress" etiological model for a subset of schizophrenia (that Kraepelin identified) with early abnormalities suggesting brain atrophy. [57]
Another paradigm, introduced by Zubin and Spring in 1977, was the stress-vulnerability model where the individual has unique characteristics that give him or her strengths or vulnerabilities to deal with stress, a predisposition for schizophrenia. More recently, with the decoding of the human genome, there had been a focus on identifying ...
The psychodynamic model is the fourth psychological model of abnormality and is based on the work of Sigmund Freud. It is based on the principles that psychological illnesses come about from repressed emotions and thoughts from experiences in the past (usually childhood), and as a result of this repression , alternative behaviour replaces what ...
