Psychlopedia - Diathesis-stress hypothesis

This finding provided evidence for the Beckian version of the diathesis-stress hypothesis�." (Lewinsohn et al., 2001, p.210) An interesting thing to note is that their positive findings for risk factor support Beck's idea that early experience leads to the formation of dysfunctional beliefs, which other studies have not been able to show.

Stress diathesis hypothesis by Rosio Stone - issuu

One of the most prominent diathesis-stress theories was developed by APS Fellow Aaron Beck, who proposed that depression onset may be attributed largely to negative cognitions and corresponding patterns of information processing. Beck’s model hypothesizes that individuals who experience adversity in childhood develop negative self-schemas that involve concepts like loss and inadequacy. These schemas are thought to remain dormant until an individual experiences a stressful life event that is reminiscent of the original stressor, at which point the schemas become activated.

The diathesis stress hypothesis by Phyllis Lloyd - issuu

A wealth of clinical data supports a major role of genetic liability as well as of altered brain dopamine (DA) functioning in different types of behavioural disturbances. Genetic influence on behaviour involves multiple genes, rather than one or two major genes, as well as non-genetic sources of variance. Thus, in recent years, increasing attention has been devoted to the involvement of stressful experiences (life events) in the development and expression of psychopathology. Moreover, a diathesis-stress hypothesis has been proposed, which suggests that the environmental factors (stress) are not specific for a given pathology, whereas genetic factors (diathesis) are. Results obtained in an animal model offer support to this hypothesis. Indeed, mice of the C57BL/6 and DBA/2 inbred strains are equally susceptible to stress but develop different behavioural disturbances related to different alterations of brain DA receptors. Moreover, quantitative trait loci (QTL) associations in the C57 (B) x DBA (D) recombinant inbred (RI) strains indicate a number of provisional QTLs influencing the behavioural effect of stress. Finally, the results of this analysis suggest the involvement of regulatory factors related to stress response and neural or synaptic plasticity in the control of brain DA receptor plasticity.

Name: J

Comments: Yes. I do believe in the Diathesis Stress Hypothesis as it concerns people with Schizophrenia because knowing my mother who grew up in foster care in 10 homes, being abused mentally and physically. She then became an alcoholic during her early adulthood and at this time she was diagnosed with schizophrenia. I always believed that her illness was because of the stress she experienced growing up. I was lucky enough to have my aunt and uncle take care of me from middle school on up to high school.

During Abnormal Psychology this week we watched A Beautiful Mind. We talked about the real Dr. John Nash who had two children one of which was living with his mother and the other one lived with him and his wife. His son that lived with him was diagnosed with Paranoid Schizophrenia. We could say the reason for that was because he was exposed to the stress of his father's illness where as his other son who lived with his mother and was not exposed to his father's illness was not diagnosed with the illness.

A related possibility is that a subgroup of those with depression have a vulnerability or diathesis, due to their genetic make-up, that affects the workings of the serotonin system, making them particularly susceptible to depression when serotonin levels are depleted.Is there any information in Table 1 which might fit in with this?To conclude, tryptophan-depletion experiments suggest that serotonin depletion has some effects on mood, but that there is no simple relationship between levels of monoamines and depression.The next section considers an even more significant problem with the monoamine hypothesis, one that has fuelled much research and has led to a more sophisticated chemical and molecular hypothesis for the aetiology of depression.
