Intergenerational Transmission of Trauma
When children are affected by a parent’s PTSD, this is understood as the intergenerational transmission of trauma, a phenomenon first recognised in Holocaust survivors’ children (Rakoff et al.,
1966). There is limited discourse around the mechanisms of intergenerational transmission of trauma from the service parent with PTSD to their child and how this differs from a civilian parent with PTSD. The discourse on intergenerational trauma generally, encompasses different areas of focus including biological or hereditary transmission through epigenetics (Yehuda & Lehrner,
2018), to factors such as family stability and or parental capacity (Banneyer et al.,
2017).
Vicarious trauma and secondary trauma are two of the most common pathologies recognised to result from intergenerational trauma.
Vicarious traumatization refers to when a child may experience a distress reaction or intrusive memory as a consequence of seeing a picture of or hearing about a parent’s experience of a traumatic event (McCann & Pearlman,
1990; McCormack & Devine,
2016).
Secondary traumatization is a broader concept that refers to the experience, impact and transfer of trauma symptoms from parent to child, where this transfer may or may not involve the child being exposed to the parent’s traumatic experiences (Diehle et al.,
2017; Figley,
1978). This phenomenon and the mechanisms of transmission were supported in the findings with indirect transmissions due to emotional dysregulation, emotional extremes and volatility, family functioning, child emulation or re-enactment of behaviour and identification with parental identity and mindset (Ancharoff et al.,
1998; Dekel & Goldblatt,
2008).
Intergenerational transmission can also involve
moral trauma or moral injury, which refers to a form of trauma experienced by military or EFR personnel when a service member perpetrates, witnesses, fails to prevent or learns about acts which transgress deeply-held moral beliefs and expectations (Litz et al.,
2009). Common symptoms and outlooks or worldviews of moral trauma in parents can impact interpersonal relationships and be adopted by children, as part of identification, such as the feelings of guilt, shame, betrayal, and hopelessness (Ancharoff et al.,
1998; Jamieson et al.,
2020; Jones,
2018).
There remains a lack of diagnostic clarity, psychometric testing in research or assessment in clinical practice and consequently, misdiagnosis of child trauma such as: complex, developmental, and intergenerational trauma (including secondary, vicarious and moral trauma), including within service families (D’Andrea et al.,
2012; Jamieson et al.,
2020; Jones,
2018; Van der Kolk,
2017). There is a growing body of research that children who have a parent with a mental illness, including PTSD, have higher rates of mental health issues (such as PTSD and depression) than children without a history of parental mental illness (Hartzell et al.,
2020; Leijdesdorff et al.,
2017; Weissman et al.,
2016). We know that a dysregulated emotional environment can affect a child’s development and their own emotional regulation, particularly from the womb to age 3–5 years, as children’s brains and nervous systems are first developing (Ford et al.,
2013).
Service Families, Culture and Identity
Being a child from a service family involves impacts on family lifestyle, culture, identity, and sometimes mental health. Studies have shown that military and emergency service vocations, with their demands of irregular hours, deployments, dangers, and trauma exposures, can have significant negative impacts on family members and family lifestyle, as well as some protective factors (Alrutz et al.,
2020; Kishon et al.,
2020; Regehr,
2005; Rogers-Baber,
2017; Wells et al.,
2022a). There is a cultural conditioning that occurs for the serving member (English,
2004; Lane & Wallace,
2020). An understanding of military culture and identity has been recognised in the literature as important when working with military and their families to understand unique risks and protective factors in these service families which would seem to translate to EFR families as well (Ohye et al.,
2017; Rogers-Baber,
2017; Tam-Seto et al.,
2019; Tanielian et al.,
2014). An Australian study focussed on the narrative and rituals of military families and found that a process of acculturation occurs in the family using stories, symbols, props, events such as ANZAC Day and other rituals to affirm the cultural identity and values in children within these families (Baber,
2016).
Both military and EFR are trained with high levels of discipline and regimentation to perform duties automatically under intense pressure and to invoke or suppress emotional reactions to mental distress and these behaviours are intended to protect the team or enable the service member to complete the task or mission in dangerous life-or-death settings (Lane & Wallace,
2020). For example, “anger” which is a learned response in training to a combat threat for service members such as military and police, channelling the automatic fear response to action (Lane et al.,
2021). This aspect of service training is significant in relation to research which shows that being “quick to anger” has a much higher symptom prevalence for veterans with PTSD, than civilians with PTSD, when triggered by an intrusive memory or perceived threat (Lawrence-Wood et al.,
2021; Van Hooff et al.,
2018a).
A recent Australian study found that children of military families who had transitioned, attributed much of their mental health difficulties and family challenges to military culture and identity (Wells et al.,
2022a). Another study found that connectedness in Defence communities was a protective factor for family members, which also highlights the need for tailored culturally sensitive and connected interventions (Rogers-Baber,
2017). The values and expectations of service, such as elevated levels of discipline, emotional intensity such as “anger” or emotional suppression, may impact family functioning and compound PTSD symptoms and create unique impacts for children of service families, compared to civilian children experiencing parental PTSD. Service culture and identity and its role in parental PTSD and capacity, as well as the children’s experiences and perceptions has been examined and reported in the findings of this paper.
Discussion
This study examined the experiences of children (aged 9–17) living with a service parent with PTSD, from the perspective of the child, the parent with PTSD and the co-parent. Overall, the perspectives of child and parent participants were complementary and contributed to a coherent set of findings. Parents reported being aware of how living with parental PTSD impacts their child’s mental health and wellbeing and openly explained that they wanted more support for their children. Children discussed their experiences of parental PTSD and were respectful, caring and protective of their parents.
As reported in a number of studies to date, the pervasive psycho-social impacts of PTSD include “significant impairment in personal, family, social, educational, occupational or other important areas of functioning” (WHO,
2018), including parent-child relationships (Banneyer et al.,
2017). Reduced parental capacity has been the aspect of intergenerational trauma transmission most discussed in the literature on military families (Banneyer et al.,
2017). There was clear evidence in this study of reduced parental capacity where dysregulated emotions and arousal states of the parent with PTSD created a lack of emotional stability for children. Children in this study experienced parental emotions that were extreme, volatile, and unpredictable, expressing concern in relation to the anger expressed by their parents and parental behaviours such as yelling. The anxiety of children around these behaviours and the way in which children were observed to emulate these behaviours was consistent with the literature on secondary trauma and intergenerational transmission of symptoms via emulation and identification (Diehle et al.,
2017).
Reduced parental capacity had a significant impact on the attachment style of the parents in this study. Some children experienced a parent who had an avoidant attachment style, being emotionally numb and not accessible for children seeking affection or support on other needs. Other children experienced a parent with an anxious attachment style, being over-protective or even paranoid, but the parent could also change to become withdrawn and reject affection, creating an anxious-ambivalent attachment style. Attachment style is an important factor influencing how children developmentally learn to manage distress (Bowlby,
1979) and affects the quality of parent-child communication (Zhou et al.,
2021).
On attachment theory, children who find it hard to interpret, access or trust the emotions and behaviours of their parents can also struggle in their other social relationships as a consequence of insecure attachment styles (Pearce,
2016). Findings of this study reflected this, with a number of children experiencing social issues expressed as emotional dysregulation (crying easily or displaying anger outbursts) or feelings of social disconnection and emotional withdrawal. The findings of insecure attachment among participants of this study reinforce the literature on the relationship between parental PTSD and insecure attachment, and they further urge the development of therapeutic interventions addressing secure attachments for children of service parents with PTSD (Rhona,
2018).
Related to attachment theory and quality of communication, the findings of this study also complemented literature about how the transmission of trauma from parent to child can occur directly through communication and behaviours or a lack of communication (Ancharoff et al.,
1998). Parental under-disclosure of past trauma exposures and/or of a diagnosis of PTSD provides evidence of this mechanism of trauma transmission, where the parents’ under-disclosure resulted in children becoming curious about what their parent has experienced to cause PTSD. Children were reported to actively seek out evidence online, in news, movies or other media, or to imagine a parent’s traumatic exposures, which may not produce accurate depictions, and to ruminate on these depictions and even experience them as their own nightmares. Our findings also featured examples of vicarious trauma, with trauma being transmitted through over-disclosure of trauma memories or parental disclosures of suicidal ideation, and also through children gaining access to a parent’s traumatic materials, such as photos, causing distress and fear.
Children mentioned being aware when a parent downplayed their mental health or gave “made-up” explanations for emotional outbursts or absences, and this inconsistency or perceived “cover up” made them feel anxious. Children expressed that they would like more disclosure, namely more explanation and information about PTSD, its causes and how it affects their parents and their family. This highlights the importance of providing developmentally appropriate explanation or psychoeducation, ongoing over the lifespan, since the impacts can change over time, which is supported by recent studies affirming a lack of age and culturally appropriate resources, for children of military families, to give them agency through recognisable narratives (Rogers & Bird,
2020; Rogers et al.,
2019). There has recently been a suite of resources created for 2–8-year-olds on military life that includes a resource on parental PTSD (Rogers et al.,
2022; Rogers,
2022).
The findings also highlight that the children need parents to strike a balance between under and over-disclosure of past trauma exposure, namely by providing children with context, but minimal details of traumatic content. Importantly, the context of the parent’s trauma exposure provided to children should include the purpose and meaning of the service-related task and setting (Bruning,
2018). This would support the child’s curiosity and understanding, helping them to make sense of their parent’s PTSD. It would also help to prevent children from attaching false imagery (imagined or sourced from media) to their parent’s pain and therein help to protect them from vicarious traumatization. This way, the exposure is more controlled, contained and meaningful, and could be supported by therapists (Bruning,
2018).
Indirect transmission of trauma was evident in this study as a result of a changed home environment including family dynamics, parental conflict, changed roles and modelling. This supports the literature on indirect transmission from family context (Dekel & Goldblatt,
2008; Sayers et al.,
2009). Evident in this study was the phenomenon of children becoming carers or taking on parental or adult responsibilities, known as parentification or adultification, which has been shown to commonly occur for children of a parent with a mental illness (Van Loon et al.,
2017). Parentification was evident to a greater or lesser degree in all the children, but it was more intense in single-parent families and ranged from taking on a carer role (supporting medical treatment compliance or protecting younger siblings), to children learning not to surprise a parent suddenly with a touch or loud noise, which children often called “managing triggers”. Parentification appeared to be an adaptive or coping behaviour of children, however the extra responsibility was also found to increase the children’s own stress or anxiety. The children’s protectiveness of their parent (another form of parentification) interfered with help-seeking. Children explained that they were nervous about seeking help, not wanting to cause their parents more stress by inadvertently bringing attention to their parent’s problems. This made the children less open to seeking help, which is a finding that ought to inform policy and services for these children.
Another key finding of this study was the evidence of impacts on child wellbeing. The feelings that children associated with their experiences of parental PTSD, predominantly anxiety, resulted in emotional and behavioural issues, which supports previous literature (Daraganova et al.,
2018; Fear et al.,
2018; Linkh,
2006; May et al.,
2023). A novel finding was that children and parents in this study doubted the accuracy of the child’s formal or suggested mental health diagnosis, which was commonly ADHD for primary school aged boys and BPD for teenage girls. These are common misdiagnoses for trauma conditions (D’Andrea et al.,
2012; Van der Kolk,
2017). This is likely because boys are most frequently diagnosed with ‘externalised’ disorders and girls with ‘internalised’ disorders (Mayes et al.,
2020), which accentuates the importance of future studies including prevalence to establish the risk, types and rates of disorder for these children.
There have been no comprehensive prevalence studies of children of service parents with PTSD (military or EFR), and secondary or vicarious trauma psychometric tools and assessment are not readily available or established in clinical practice. We know that parental mental health issues increase the risk of child mental health issues in the general population (Weissman et al.,
2016). We also know of increased mental health issues in adult children of military parents with PTSD (O’Toole et al.,
2017). And we know that emotional and behavioural issues are more readily identifiable in children of EFR or military parents with PTSD (Daraganova et al.,
2018; Fear et al.,
2018; Linkh,
2006; May et al.,
2023). But this knowledge base is inadequate to guide widespread policy, support services and intervention.
Children in this study experienced anxiety and fear of separation post-service, just as children did in a study of families of EFRs impacted by the 9/11 World Trade Centre Attacks (Linkh,
2006). The children have prior experiences of fear of the dangers inherent in their parent’s service and prior experiences of separation anxiety when their parent was absent due to deployments (local or overseas) (Rogers,
2020; Siebler,
2009; Wells et al.,
2022a). The absence of parents, emotionally or physically, post-service due to PTSD reinforces the children’s memories and heightens the associated feelings of anxiety and fear (Brooks,
1981). This needs to be recognised in supporting these children.
Children’s fear of loss and experiences of parental suicidality are traumatic for them, even without the tragedy of completion. This is especially important to highlight in view of the Australian Royal Commission into Defence and Veteran Suicide, a national enquiry. This study supports the literature on suicide risks through moral trauma and interpersonal impacts (Jamieson et al.,
2020). It shows how difficulties interpersonally for service parents with PTSD, feeling guilt around the impacts on their children and partner and frustration at the difficulty of accessing help for them, increases distress and risk of suicide, and consequently distresses the children. EFR families had even greater difficulty accessing help for their children or partners, due to there being no established government funding for EFR families of injured members during or post-service. Supports have improved for veteran family members who can access some counselling through the Department of Veteran Affairs agency; Open Arms in Australia, with limitations to eligibility, but EFR family members have very few services, in a state administered EFR structure with support systems for current members through an organisation’s mental health service for employees, usually called Employee Assistance Programs (EAP) or injured members via insurance schemes, which is similar in New Zealand, Canada and Unites States of America (Alrutz et al.,
2020; May et al.,
2023).
The findings of this study are some of the first to explicitly identify the mechanisms of inter-generational transmission of trauma in service families, detailing the direct and indirect mechanisms and the outcomes of vicarious, secondary and moral trauma for children. The transmission of moral trauma from parent to child (Jones,
2018) was also identified in this study, where some children mirrored their parent’s worldview of feeling ashamed, betrayed, discarded, misunderstood, unappreciated, disconnected from their community, and felt hopeless or powerless to change this (Jamieson et al.,
2020). Meaning making to improve their understanding, sense of purpose and narrative behind their experiences of parental PTSD, needs to be part of interventions for children of service families to address moral trauma and support their wellbeing (Bruning,
2018).
Within our findings on help-seeking, an area of focus was the school setting, which is consistent with the literature (Esqueda et al.,
2012; Garner & Nunnery,
2018; Macdonald,
2017; Macdonald & Boon,
2014; Rogers et al.,
2021; Wells et al.,
2022b). Parents described that they often did not realise fully that their children were experiencing emotional or behavioural issues until teachers and school staff raised it. Parents described many examples of schools not understanding or providing support for their child’s and family’s difficulties, even when they disclosed this to the school, raising the issue of a lack of capacity in schools and school counsellors. Improving the capacity of schools to support children of service families was also a finding supported in the literature and includes the need for service cultural knowledge and practice within schools (Macdonald,
2017). Some children said that participating in this research was the first time they had been asked about how their service parent’s PTSD affected them, by anyone, and they explained that more information and help for them and their parents would have made talking about it easier. This supports the parents’ identification of a need for policy and practice to equip schools and service providers with more information guides and programmes on parental PTSD in service families.
The recently developed resources for educators and families of 2–8-year-olds on military life and parental PTSD will help support some of this knowledge in Australia and hopefully EFR families in the future (Rogers et al.,
2022; Rogers,
2022). The Australian Defence Force have also funded a programme previously called Defence School Transition Aides and more recently named Defence School Mentors, which focuses on children of current Defence members, and primarily deployment periods, however research supports that this programme could be expanded to support other children with parents who are away for long periods such as children of EFR families (Macdonald,
2017) and also needs to be expanded, to support for children of injured veterans or EFRs with PTSD for example.
This study reveals the additional impact of service culture and identity on the way a child is impacted by parental PTSD in service families. With intense emotions such as “anger” being a trained combat response to threat for service members such as military and police, it becomes an automatic response to traumatic memories (Lane et al.,
2021). In this study, children reported that anger and yelling is one of their greatest concerns. Fluctuating arousal and emotional states, such as high levels of anger in service parents with PTSD, effectively fatigue the nervous system and become automatic reactions, which are hard to change for adults (Lawrence-Wood et al.,
2021; Van der Kolk,
2015) and are ultimately being modelled or transmitted to children in the parenting environment (Diehle et al.,
2017; Parsons et al.,
2018). This important finding needs to be implemented using service cultural awareness in the design of interventions for children of service families and parents, to support them to learn new skills to manage and regulate their emotions and behaviours.
The help-seeking family members in this study reported that they had experienced a major gap in the lack of culturally attuned and appropriate services for their child and family. The literature also confirms that there is a paucity of research into therapeutic interventions designed and evaluated to support the well-being of children of service parents with PTSD (Ohye et al.,
2017; Rogers et al.,
2021). Understanding “military or service cultural competency” is recommended in the literature to be a key aspect of the design and development of effective treatments for service members and their families (Cramm et al.,
2021; Lane et al.,
2021; Ohye et al.,
2017; Tam-Seto et al.,
2019).
There are several strengths and limitations of this study. The COVID-19 pandemic hampered recruitment and whilst the sample size of 17 participants was sufficient for the study design, a larger study may support greater confidence and transferability of the findings. We also recommend a larger mixed-method study of experiences and also prevalence of intergenerational transmission in children of service families to enhance understanding of risk, types and rates of disorder. While age range of children in this study was limited to children aged 9–17 due to methodological and ethical reasons, this is not considered a major limitation as children’s voices in general are very rarely incorporated into research of this type, with most studies of military or EFR families focused on adult children.
There are very few studies published worldwide that have examined the experiences of children from the perspective of the child, the service parent with PTSD and the co-parent. Parental PTSD in this study was ascertained based on self-report and did not require proof of diagnosis for participation. This approach was taken to increase participation and reduce risk of distress to the family. Given the focus on parental PTSD, the findings of this study cannot be generalised to PTSD comorbidities or other mental health conditions of service. A major strength of this study is the participants who gave candid emotional accounts of their own personal experiences as children and parents. The participants, including children as young as 9 years, expressed that they wanted to participate in the research with the hope and aim that sharing their stories may inform improvements in support services for other children and families living with service-related PTSD.
