AP PSYCHOLOGY

Detailed explanation-1: -The diathesis-stress model, also known as the vulnerability–stress model, is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and stress caused by life experiences.

Detailed explanation-2: -The diathesis-stress model posits that psychological disorders result from an interaction between inherent vulnerability and environmental stressors. Such interactions between dispositional and environmental factors have been demonstrated in psychopathology research.

Detailed explanation-3: -Diathesis refers to a predisposition or vulnerability to developing a mental disorder. This can be due to genetic factors, early life experiences, or other biological susceptibilities. Stress refers to the environmental factors that trigger the onset of mental illness or exacerbate existing conditions.

Detailed explanation-4: -the theory that mental and physical disorders develop from a genetic or biological predisposition for that illness (diathesis) combined with stressful conditions that play a precipitating or facilitating role.

Detailed explanation-5: -The diathesis-stress theory for depression states that the effects of stress on the depression risk are dependent on the diathesis or vulnerability, implying multiplicative interactive effects on the liability scale.
