What psychological model emphasizes stress interaction with predisposed vulnerabilities?

The diathesis-stress model is crucial for understanding how psychological disorders may develop as a result of both genetic predispositions and environmental stressors. This model suggests that individuals may have underlying vulnerabilities, or "diatheses," which can interact with stressful life events to trigger the onset of mental health issues.

This model acknowledges that not everyone who experiences stress will develop a disorder; it is the combination of both the predisposition and the external stresses that leads to the manifestation of psychological problems. For example, someone with a genetic predisposition to anxiety may only experience significant anxiety disorders when they encounter major stressors in their life, such as loss, trauma, or chronic stress.

In contrast, the other models focus on different aspects of behavior and mental health. The behavioral model primarily addresses learned behaviors and how they can be modified, without necessarily considering genetic or predisposed vulnerabilities. The cognitive model emphasizes thought patterns and how they affect feelings and behaviors, while the psychoanalytic model focuses on unconscious conflicts and early experiences. These perspectives do not inherently incorporate the interaction between stress and individual vulnerabilities to the same extent as the diathesis-stress model.
