Stress-Vulnerability Model

The Stress-Vulnerability Model is a tool that explains how and why mental health problems arise. Read on to learn more about the vulnerability stress model, some criticism it has received, the impact stress can have on us, and ways to boost protective factors to fight against stress.

History of the Stress-Vulnerability Model

The Stress-Vulnerability Model was developed in 1977 by Zubin and Spring to explain the development of schizophrenia.

After its initial introduction to the mental health world, the model extended to include a broad range of psychiatric diagnoses.

Criticism of the Stress-Vulnerability Model

While the Stress-Vulnerability Model has been instrumental in helping us better understand psychiatric ailments, it hasn’t been without its critics.

The Term 'Vulnerability' Is Limiting

A 2022 article published in Frontiers in Sociology1 found the model’s focus on vulnerability to be disempowering. Noting the nearly 50 years that have passed since the model was introduced, the article found the model’s emphasis on vulnerability to be a distraction from the actual harm at hand.

What Are the Elements of the Stress-Vulnerability Model?

According to the Stress-Vulnerability Model, biological vulnerability and stressors are responsible for developing a psychiatric disorder. Then, protective factors are what can help reduce biological vulnerability and stress.

3.Protective Factors

Biological Vulnerability

Biological vulnerability refers to one’s genetic predisposition. For example, bipolar disorder is known to have a genetic link and is often passed down in families.

Stress

While stress can contribute to developing a mental health disorder, it isn't the only factor at play. For example, someone may already have a genetic predisposition to a mental health disorder, but they have not developed it yet.

Examples of these life stressors include:

•Life crises (e.g., death of a loved one, major illness)

•Substance use

•Personal and job-related stressors

When this significant life crisis occurs, some of the disorder's symptoms can emerge. However, remember that the probability of this depends on the type of psychiatric condition the person is predisposed to.

Protective Factors

Protective factors are critical in reducing both stress and biological vulnerability.

Protective factors can include:

•A support system with individuals who have strong communication skills

•A structured daily routine

•A low-stress lifestyle

The Bottom Line

If you're experiencing stress or trauma, please know that you are not alone. A mental health professional can help support you in your healing process.
