Stress–Vulnerability Model
The Stress–Vulnerability Model, also known as the Stress–Diathesis Model, is a
biopsychosocial theory that explains how mental health difficulties develop
through the interaction between an individual's underlying vulnerability and
exposure to stressful life events. The model proposes that vulnerability alone
does not necessarily lead to mental illness, and neither does stress in isolation.
Instead, mental health problems are more likely to arise when significant stress
exceeds an individual's capacity to cope, particularly in the presence of
biological, psychological or social vulnerabilities. Within social work, the Stress–
Vulnerability Model helps practitioners understand the complex causes of mental
distress while promoting holistic, person-centred and recovery-oriented
interventions (Zubin & Spring, 1977).
The Stress–Vulnerability Model was developed by psychologists Joseph Zubin and
Bonnie Spring in 1977 to explain why some individuals develop mental health
conditions following stressful experiences while others do not. Earlier approaches
often viewed mental illness as either biologically determined or solely the result
of environmental stress. Zubin and Spring argued that both factors interact,
recognising that genetics, brain function, personality, trauma and social
circumstances all influence an individual's susceptibility to mental illness. Since
its development, the model has become widely used within psychiatry,
psychology and social work to understand conditions such as schizophrenia,
depression, bipolar disorder and anxiety disorders (Zubin & Spring, 1977).
A central principle of the Stress–Vulnerability Model is vulnerability (or diathesis).
Vulnerability refers to an individual's predisposition to developing mental health
difficulties. This vulnerability may be biological, such as genetic factors or
neurological differences; psychological, including personality traits or previous
trauma; or social, such as childhood adversity, poverty or discrimination. Having
a vulnerability does not mean that mental illness is inevitable, but it may
increase the likelihood of difficulties developing when combined with significant
stress.
The second key component is stress. Stress refers to internal or external
pressures that challenge an individual's ability to cope. Examples include
bereavement, relationship breakdown, unemployment, financial hardship,
physical illness, academic pressure, discrimination or major life transitions. The
