According to the stress-vulnerability model, what can exacerbate a person's genetic susceptibility to psychosis?

The stress-vulnerability model posits that an individual's genetic vulnerability to mental health disorders, such as psychosis, can be worsened by certain environmental factors. These environmental risk factors may include stressful life events, trauma, substance abuse, or other social determinants that can trigger or increase the intensity of a mental health condition in those who are already predisposed genetically. The interplay between these external stressors and an individual's inherent vulnerability is crucial in understanding the onset or exacerbation of psychotic disorders.

Positive thinking, historical awareness, and regular exercise, while beneficial to overall well-being and mental health, do not directly contribute to exacerbating genetic susceptibility. In fact, positive thinking and regular exercise are often associated with reducing stress and improving mental health outcomes. Hence, the focus on environmental factors in this model highlights the critical role that context and life experiences play in the development of psychosis in those with genetic predispositions.
