This week’s term is diathesis-stress model.
Central is the assumption that are necessary for the development of failure both diathesis and stress. In line with its focus on the neurobiology of stress response in schizophrenia, this model treats stressors as a homogeneous category. The diathesis - stress model ( vulnerability-stress model) is a paradigm of clinical psychology and health psychology, which is not set to a particular school and biological, psychological and environmental factors connects.

Schizophrenia can be explained by the stress-diathesis model.

For instance, early diathesis-stress models assumed that a disorder manifests when stress activates a diathesis.
Although the diathesis-stress model provides a valuable conceptual framework for developing theories of psychopathology, the general model alone may represent an overly simplistic view of how psychological disorders develop. Onset of a disorder can then be triggered by environmental stress; however, the amount or intensity of stress required to trigger a disorder depends on the extent to which the individual is inherently vulnerable. According to the general model, each individual possesses some degree of inherent vulnerability (i.e., diathesis) for developing a given disorder. Schizotaxia, schizotypy, schizophrenia.

Bleuler, M. (1963). Accordingly, schizophrenia vulnerable people are characterized by a lack of resilience, ie a particular vulnerability and sensitivity ( " thin-skinned " ) that the association is unfavorable case with stressful life history, situational- social or physical and hormonal stress to the onset of psychosis. A child may have inherited the gene from their parents (nature). With a background in industry, Melanie has supported teachers of Health and Social Care through numerous CPD projects and is an experienced examiner.
Although both stress and vulnerability factors have long been associated with the development of psychopathology, the two components were not integrated within a unified model of psychopathology until theories of schizophrenia were proposed in the 1960s (e.g., Meehl 1962). Schizophrenia as a complex trait: Evidence from a meta-analysis of twin studies. 103.5.51.154. For example, the greater an individual’s vulnerability to a disorder, the smaller the amount of stress needed to trigger the development of the disorder.
The stress-diathesis model is the explanation that a disorder or behaviour trait is the result of an interaction between genetic predisposition vulnerability and stress, usually caused by life events and factors. (1995) found that genetic risk and stressful life interacted to predict the onset of major depressive episodes in a study of female-female twin pairs. According to Meehl’s model of schizophrenia, an inherited genetic vulnerability (which he termed schizotaxia) predisposes individuals to develop a schizotypic personality which has the potential of decompensating into clinical schizophrenia.
For a more vulnerable person, less environmental stress is necessary to trigger a mental illness. (2003) conducted a meta-analysis to examine the impact of genetic and environmental factors on liability to schizophrenia. In other words, dispositional factors can influence the individual’s environment in such a way that contributes to the development of the disorder.
Research using family studies have suggested a genetic vulnerability is inherited and this varies from those with a high vulnerability to a low vulnerability. This service is more advanced with JavaScript available. In D. Rosenthal (Ed.).
