Understanding Intergenerational Trauma and Its Effects on Family Mental Health

understanding-intergenerational-trauma-and-its-effects-on-family-mental-health

History suggests that once the atrocity is over, it ceases to exist. Colonisation, slavery, cultural erasure and other acts aimed toward marginalised groups across the world only seem to impact the groups when they are being acted upon. History does not make space for the burden of systemic discrimination, atrocities, injustice, and pain that emanate from these experiences and are interwoven into the identity of the victim group.

These scars of deep trauma are not only experienced by the victims but slowly trickle down through generations. Such trauma lives on, not just in physical bodies but across generations, shaping mental health decades after the first infliction of pain.

What is Intergenerational Trauma?

Also known as ‘Transgenerational Trauma’, this type of trauma forms an agonising legacy of the original inflicted pain. It is the trauma experienced by subsequent generations without direct exposure to the original event (Cacace & Summers, 2025). The study of such phenomena emerged in literature through the experiences of the generation born to Holocaust survivors (Yehuda & Lehrner, 2018). 

The transmission of this form of trauma manifests as psychological consequences of pain that might have been inflicted upon an individual’s predecessors ages ago (APA Dictionary of Psychology, n.d.). Literature aims to understand how such experiences and their effects are transferred from generation to generation, allowing even those who have never witnessed such atrocities to carry the psychological burden of them. A few of the transmission mechanisms suggested by research are:

1. Genetic Alteration

The transference of trauma is believed to have an epigenetic basis, suggesting that trauma can inherently alter a gene and its expression (Rando, 2016). Literature also suggests that offspring are affected by parental trauma even before birth and possibly before their conception because of the impact of trauma on genetic markers and carriers (Yehuda & Lehrner, 2018). A common example is the alteration of the body’s stress response, which changes predisposition to anxiety, depression and more as a result of altered DNA linked with intergenerational trauma (Jiang et al., 2019).

2. Psychological Mechanisms

understanding-intergenerational-trauma-and-its-effects

Several basic mechanisms allow for the transmission of trauma across multiple generations and can be assumed to have a mediating role in allowing such cycles to pervade. The attachment formed between parents and children is considered one of the negative experiences that can affect a generation and have an impact on the subsequent generation as well (Gravener et al., 2011). Simultaneously, the presence of unresolved trauma will impact family dynamics, parenting styles, behaviours and allow for the perpetuation of negative core beliefs, fundamentally impacting future generations.

3. Social Factors

Historical notes indicate that the social implications of traumatic events also manifest as socio-economic factors. This suggests that issues such as poverty, discrimination and oppression, which arise as a result of events of the past, will continue to have an impact on the present as well. Simultaneously, cultural factors such as loss of identity and tradition will also play a significant role in the perpetuation of intergenerational trauma (Bowe et al., 2025).

Foundation of Trauma in Minority Communities

Adverse childhood experiences, abuse, oppression, and more can lead to the formation of trauma in an individual. However, history is proof that minority groups are almost always more likely to be victims of such traumatic events (Roberts et al., 2010). The intersection of a variety of events, ranging from colonisation to cultural erasure and loss of cultural identity, allows minority communities to experience a higher risk and greater intensity of generational trauma.

1. Chronic Oppression

understanding-intergenerational-trauma-and-its-effects-on-family

Minority groups are more likely to be victims of chronic oppression and systemic discrimination, which can be found in multiple facets of their lives. These negative experiences can lead to constant stress, impaired self-view view and the disruption of psychological well-being, all of which can persist into future generations and result in a range of challenges (Williams et al., 2023).

2. Loss of Culture

Culture provides a sense of belonging and shapes an individual’s identity. However, the loss of culture along with its practices, traditions and values can lead to an individual feeling lost and without connection. The integrative nature of culture with social structures and community suggests why the loss of culture will lead to lower social cohesion and create community mental health challenges, further worsening well-being. To escape the trauma being inflicted upon them, minority groups will often aviator on cultural identities and begin to adopt those of the majority, which not only leads to cultural erasure but also becomes a form of trauma in itself (Ford et al., 2015). 

3. Historical Silencing

It is commonly believed that history is written by those who are the victors of the various wars that have been fought across civilisation. Historical texts do not account for those members of the LGBTQ+ community who have been excluded or suppressed from mainstream discourse. The underrepresentation of minority groups in history, along with the belief that they must not speak of their experiences, can lead to internalised shame and disrupted identity (Mohatt et al., 2014).

The experiences of minority groups have been thwarted by social injustices across history, especially in India. Colonisation, caste-based discrimination, the partition, religious discrimination, stigmatisation of certain groups, and other events that form the history of the country form the historical roots of inter-generational trauma in minority communities.

How Trauma from the Past Moulds Mental Health in the Present? 

The pervasive nature of intergenerational trauma allows it to have a profound impact on mental health in those individuals who exist long after the event that initially caused the trauma. It also tends to go unrecognised, silenced and unaddressed, allowing its roots to spread over every aspect of one’s life. The earliest accounts of intergenerational trauma also suggested that it almost seemed like the impact of the trauma skipped the survivors of the events and was directly passed down to their children, manifesting as behavioural and emotional problems (Rakoff, 1966).

1. Increased likelihood of developing Mental Health Disorders

Intergenerational Trauma leads to a heightened vulnerability to mental health disorders. Ullah et al. (2023) suggest that it is a silent contributor to the deterioration of overall mental well-being and health. Not only does it lead to the manifestation of disorders like depression, anxiety, and post-traumatic stress disorder (Raypole, 2022), but it has also been linked with neurodevelopmental disorders (Alhassen et al., 2021).

2. Hypervigilance and Increased Stress Response

Epigenetic alterations at the hands of transmission of trauma across generations have systematically altered an individual’s stress response at a DNA and molecular level (Jiang et al., 2019). It can manifest as a form of heightened state of alertness or hypervigilance, creating a tendency to be on guard. This maladaptive stress response can also be linked to a greater proclivity to anxiety disorders and phobias (Cacace & Summers, 2025). This response may mirror the emotional landscape of the ancestor’s experience of the traumatic event. 

3. Maladaptive Attachments and Parenting Styles

understanding-intergenerational-trauma-and-its-effects-on-family-mental

Intergenerational trauma leads to emotional dysregulation and will disrupt an individual’s ability to emotionally bond with others, allowing maladaptive attachment styles and parenting behaviours to arise. Especially in the case of minority groups who often face ongoing oppression, they direct most of their efforts towards ensuring the safety of their loved ones rather than creating healthy, emotional connections with them. These patterns of survival are learnt by the children, allowing feelings of insecurity, fear, and even confusion about emotional expression to arise. (Kostova & Matanova, 2024)

4. Loss of Identity

The very nature of intergenerational trauma in minority groups ties the experience with aspects of one’s identity, such as race, caste, culture, or even religion. When such a negative experience closely integrates with one’s identity, an individual finds it very difficult to keep aligning with that identity. Individuals may begin to adopt different attitudes, behaviours, and presenting indicators which will differentiate them from the identity of the minority group, allowing them to escape continued oppression as well as traumatic experiences (Ullah et al., 2023).

5. Substance Use and Other Coping Mechanisms

While it is inaccurate to believe that substance use and other maladaptive coping mechanisms are inherently more likely to exist in individuals from minority groups, research suggests that various socioeconomic factors can increase the risk for the same. Various factors such as poverty, lack of access to healthcare, experiences of oppression, racism and other social evils can increase the likelihood of substance use (Cook & Alegría, 2011). Families learn and pass down these coping mechanisms across multiple generations, allowing them to persist even when the socioeconomic disparities faced by the minority group no longer exist (Jones et al., 2023). 

A Way Ahead

Intergenerational trauma is a presence that continues to shape mental health relationships and even identities of individuals and communities, particularly within minority populations, long after the traumatic event has ended. Histories of injustice, violence, oppression, and more silently transmit this trauma through various behaviours, patterns, family dynamics, and even genetics. It is a form of trauma that is so pervasive that it can impact all facets of an individual’s life, yet remains overlooked in mainstream discourse and clinical practice. 

However, with the consistent efforts of Psychology today, individuals can aim to actively break this cycle of intergenerational trauma. With the rise of culturally sensitive, therapeutic models, community-based interventions, trauma-informed care and more, communities can process the pain they have inherited from their ancestors, reclaim their narratives and begin healing. With resilience, victims of intergenerational trauma work towards recovery and aim to build a future where the wounds of their past no longer dictate their mental well-being.

FAQs

1. Can a family pass on intergenerational trauma even if they don’t discuss the traumatic event?

The mechanisms that transfer intergenerational trauma related to minority groups across generations go beyond simply talking about it. Research shows that intergenerational trauma causes epigenetic changes, which manifest as irregular stress responses. The trauma will impact emotional bonds, parent-child relationships, identity, and even the approach an individual has towards their own community. These experiences have a fundamentally larger impact on the younger generation, allowing intergenerational trauma to persist. However, we must note that avoiding conversations about traumatic events can allow intergenerational trauma to persist. This becomes especially true when those events connect to an individual’s minority group identity.

2. How do I know if my struggles are related to Intergenerational Trauma and not my own experiences?

For an individual dealing with the aftermath of any type of trauma. It can be very difficult to understand what is impacting them. This is especially true in the case of intergenerational trauma. Such trauma exists in all aspects of an individual’s life, making it hard to understand its extent. However, if an individual feels that their emotional patterns are disproportionate to their personal experiences, it may be a sign. This is particularly relevant when their minority group identity shapes the situation. Therapy can help identify these links.

3. Can the experiences of Minority Groups and their trauma help an individual from the group feel empowered?

Yes, in a lot of cases, the painful history of minority groups can actually help an individual with the same identity feel empowered. This is possible as long as they take efforts to rewrite the narrative. Doing so requires a lot of resilience and strength. Both the individual and the community need to work together to fundamentally change the perspective they adopt towards their history.

4. Are there any cultural practices that can help prevent intergenerational trauma?

To mitigate the impacts of traumatic events in the past related to a minority identity, the individuals of the group can take specific efforts. These efforts help prevent intergenerational trauma. They are often cultural or community-specific. They may take the form of art, storytelling, music, spirituality, rituals, or even collective mourning and celebration.
