Final answer:
The most accepted explanation for mental illness, combining genetic vulnerability and negative environmental stressors, is the biopsychosocial model.
Step-by-step explanation:
The most accepted explanation for mental illness that combines genetic vulnerability and negative environmental stressors is the biopsychosocial model. This model suggests that mental illness is influenced by a combination of biological, psychological, and social factors. The genetic vulnerability refers to an individual's genetic predisposition to certain mental disorders, while negative environmental stressors can include factors such as childhood trauma, stressful life events, or dysfunctional family environments.
A prominent example of this model can be seen in the development of schizophrenia. Research has found that individuals with a high genetic risk for schizophrenia are more likely to develop the disorder if they are raised in disturbed home environments. This evidence suggests that both genetic vulnerability and environmental stressors are necessary for schizophrenia to manifest.
