Definition of Diathesis-Stress Theory:

In psychology, the Diathesis-Stress Theory is a theoretical framework that explains how a combination of predispositions (diathesis) and external stressors interact to influence the development of a disorder or illness.

Subtitles:

1. Diathesis:

A diathesis refers to a preexisting vulnerability or susceptibility to a particular condition, which could be influenced by genetic, biological, or psychological factors.

2. Stress:

Stress refers to external factors or events that trigger or exacerbate a person’s vulnerability to develop a disorder or illness. Stressors can include traumatic experiences, life events, environmental factors, or chronic stress.

3. Interaction:

The Diathesis-Stress Theory proposes that the manifestation or development of a disorder or illness results from the interaction between a person’s diathesis and the level or intensity of stress they experience.

4. Threshold:

According to this theory, individuals have a threshold or tipping point, beyond which the combined influence of their diathesis and stress may lead to the onset or exacerbation of a disorder. The threshold varies between individuals and can be different for different disorders.

5. Protective Factors:

Protective factors are factors that can mitigate the impact of stress and reduce the likelihood of developing a disorder. These protective factors could include social support, coping skills, resilience, and positive life experiences.

6. Applicability:

The Diathesis-Stress Theory is applied in various psychological and medical fields to understand the etiology, course, and treatment of disorders such as depression, anxiety disorders, schizophrenia, and substance use disorders.

7. Holistic Approach:

This theory emphasizes the importance of considering both individual vulnerabilities (diathesis) and environmental factors (stress) together to gain a comprehensive understanding of the development of disorders, suggesting that neither factor alone is sufficient to account for the occurrence of psychopathology.
