What is the Stress Vulnerability Model?

The Stress Vulnerability model given by Spring and Zubin in 1977 signifies why some people are more vulnerable to acquiring mental illnesses. This model follows the interplay of factors like biological, environmental, and protective factors for the identification and intervention of mental and psychological disorders. When the level of stress crosses the limit of coping strategy, it is highly likely to be vulnerable to mental illnesses.

Biological Factors and Vulnerability

Genetic influences:

According to research, few genes can increase the susceptibility to mental illnesses, especially depression, schizophrenia, and bipolar disorder. The way neurotransmitters work in our brain, the structuration of the brain, regulation of stress hormones – all these factors are manipulated by certain genes identified in studies. Along with this, the neurobiology of the brain also comes into play. Serotonin and dopamine, the major neurotransmitter mechanism with the HPA axis (hypothalamic-pituitary-adrenal) directly manipulate the way an individual perceives and reacts to external stress.

Environmental Stressors:

There are a wide variety of environmental factors with diverse events such as employment insecurity, death of a loved one, and disruption in interpersonal relationships. When these conditions continue for a prolonged period, the coping mechanism of an individual gets tremendously damaged and weakened.

How is the stress vulnerability model useful?

Assessment and Diagnosis:

Mental health professionals implement the stress vulnerability model for the screening and assessment of mental illnesses. The risk factors can be evaluated through this model along with customization and personalization of the interventional management.

This is possibly by building up and sustaining protective factors, it can be immediate aid or a long-term solution as well. Some of the examples include encouragement and support for the individual in continuing with medications and avoidance of substance abuse such as alcohol as an escape.
