Intergenerational trauma refers to the apparent transmission of trauma between generations of a family. People who experienced adverse childhood experiences growing up, or who survived historical disasters or traumas , may pass the effects of those traumas on to their children or grandchildren, through their genes , their behavior, or both, leaving the next generation susceptible to anxiety , depression , hypervigilance, and other emotional and mental health concerns.
Defining Intergenerational Trauma
Intergenerational Trauma is one of the most studied topics in modern psychology and mental health. At its core, intergenerational trauma involves a specific cluster of experiences — cognitive, emotional, and physical — that have been consistently identified across cultures and research populations.
Psychologists define intergenerational trauma using diagnostic criteria that have been refined over decades of clinical and empirical work. The core features include recognizable patterns that distinguish intergenerational trauma from related but distinct conditions.
Who Does Intergenerational Trauma Affect?
Intergenerational Trauma affects people across all demographics, though certain factors can increase vulnerability:
- Age: Can emerge at any life stage; some forms peak in specific age groups
- Biology: Genetic predisposition plays a role for many types of intergenerational trauma
- Environment: Life experiences, stress, and social factors contribute significantly
- Co-occurring conditions: Intergenerational Trauma often appears alongside other psychological conditions
The Spectrum of Intergenerational Trauma
Like most psychological phenomena, intergenerational trauma exists on a spectrum. Mild experiences are part of normal human life. The concern arises when intergenerational trauma is persistent, intense, and interferes with daily functioning — work, relationships, or basic self-care.
Clinicians assess severity by looking at duration (how long), frequency (how often), and impairment (how much it affects daily life).
When to Seek Help
Consider professional support if intergenerational trauma:
- Persists for more than a few weeks
- Interferes with work, school, or relationships
- Causes significant distress
- Involves thoughts of self-harm
