What model suggests that biological vulnerabilities for a disorder interact with experiences of stress?

The Diathesis-stress model is a psychological framework that posits that mental disorders develop as a result of the interaction between a person’s biological vulnerabilities (diathesis) and environmental stressors. According to this model, individuals may inherit certain predispositions for mental health issues, which become activated in the presence of stress or adverse experiences. This means that while someone may have a genetic or biological tendency toward a disorder, it typically requires external stressors or conflicts to trigger the manifestation of the disorder.

This model helps explain why some individuals with a family history of mental illness may experience these conditions under stress, while others do not, highlighting the importance of both innate predispositions and life experiences in the development of psychological disorders.
