The diathesis-stress model posits that psychological disorders develop as a result of an interaction between an individual's predisposition to a disorder (the diathesis) and environmental stressors. This model highlights that while someone may have a genetic or psychological vulnerability to certain mental health issues, it is the presence of stressors—such as trauma, loss, or daily life pressures—that triggers the onset of these disorders.

In essence, the diathesis represents inherent risk factors, which could be genetic, biological, or personality traits, while stressors are external events or circumstances that can activate these vulnerabilities. The model underscores that both elements are integral to understanding the complexity of psychological disorders, providing a more nuanced view than suggesting that mental health issues arise from either genetic or environmental factors alone. This makes the combination of predisposition and stress the correct and comprehensive answer, as it captures the multifaceted nature of psychological disorder development.
