In March 2021 we joined CAMHS around the Campfire, the online journal club run by ACAMH with the Mental Elf, to discuss Rachel’s recent paper on complex posttraumatic stress disorder (PTSD) in young people in care.1 Briefly, this paper presented results of a longitudinal study exploring the role of key cognitive predictors of both ‘standard’ PTSD and complex PTSD symptoms. The sample included 120 10-18 year-olds living in care in England. The study found that our current models of PTSD were applicable to young people in care. Maladaptive cognitions (e.g., “I can’t trust anyone” or “the world isn’t safe”), cognitive coping (e.g., avoiding thinking about what happened), and memory qualities (e.g., memories being muddled or confused) were all associated with PTSD symptoms and complex features. Maladaptive cognitions were particularly important. This suggests that targeting these mechanisms in intervention would be useful for young people with complex PTSD symptoms. In this article we reflect on some of the important points raised in the Campfire discussion about this research.

Are PTSD and complex PTSD different?

PTSD is a trauma-specific mental health difficulty. A young person who has experienced trauma (whether that might be called maltreatment, complex trauma, developmental trauma, or any other trauma exposure) is at risk of developing PTSD. According to the World Health Organisation’s diagnostic classification system (ICD-11), PTSD includes three symptom clusters: re-experiencing the trauma, avoiding reminders of the trauma and hyper-arousal. Young people with PTSD commonly also have other mental health problems, such as depression or anxiety. We know that rates of PTSD are very high in care-experienced young people. Complex PTSD is a new diagnosis in the ICD-11, but has not been included in the American Psychiatric Association’s diagnostic classification system (DSM-5). Crucially, to meet criteria for complex PTSD, the young person must have PTSD as well as additional complex features of difficulties with: relationships, emotion dysregulation and negative self-concept (e.g., “I’m not worth anything”).

Rachel’s work indicates that the same processes that drive PTSD, also drive complex PTSD. This suggests we may not need to develop completely new treatments for complex PTSD. We already have interventions that target these processes – called trauma-focused cognitive behaviour therapies (tf-CBT), the NICE-recommended first-line treatment for PTSD.2 There is growing research supporting this by showing that tf-CBT is an effective treatment for those with complex presentations.3 It’s possible that young people with complex presentations may benefit from more sessions to allow a more in-depth focus on certain aspects of treatment.

Getting young people in care the right treatment

It’s important that young people in care get the right treatment to address their needs. We know that even our best evidenced treatments do not work 100% of the time for 100% of young people, but they should be the starting point to giving young people the best chance at overcoming their mental health difficulty.

As with any treatment, it is also important that the young person receives appropriate psychoeducation, not just about PTSD, but also about the treatment. People with PTSD often want to avoid thinking about what they have been through, which means they might struggle to engage in earlier sessions or not turn up to some sessions. In the psychoeducation component of tf-CBT it is important that avoidance is openly discussed. Similarly, it can be useful for practitioners to reflect on whether they may inadvertently encourage avoidance by delaying starting parts of treatment that are harder, such as memory work.

We also acknowledge the barriers that often exist in services that might mean practitioners find it difficult to deliver tf-CBT. It might be that they are not able to provide the required 12-20 sessions, or that they do not have training and supervision available to them. But there also seems to be a pervasive belief that tf-CBT is not appropriate for young people exposed to complex trauma, like abuse. This belief is not supported by the evidence or the most recent NICE review for PTSD, and is also challenged by mechanism research. Understanding how we can address service-level and individual-level barriers remains an important area of research, so practitioners and services can be encouraged and supported to deliver evidence-based treatments, such as tf-CBT.

Listening to young people in care

Another important issue is the need for researchers and practitioners to listen to, and genuinely hear, the views of young people in care. Young people in care are young people first – they are as different to each other as any group of young people. Some young people we have spoken to had gone for mental health support, only to feel let down by not receiving support that helped them. Some felt so let down that they decided never to engage with mental health services again. Aishat, a young person with care experience, spoke from her own experience about feeling patronised and let down by her initial contact with services. She felt that her initial experience seeking professional help was met with a lack of validation of the mental preparation it had taken her to even ask for help. Aishat felt that professionals often overrode her experience with their own assumptions. She talked about often feeling rushed and not being given the opportunity to talk about her experiences, and that she had sometimes felt that her memories were being invalidated or judged as biased or inaccurate. Aishat believes it is important to recognise the time it may take for a young person to truly scrutinise their trauma and accept its effects; bombarding them with information they’re not ready to receive will only hinder rather than help the process. Because of the trauma experienced by young people in care, it seems we sometimes just accept that mental health difficulties are inevitable or unchangeable. We all agree that it is vital that we challenge this assumption, especially because young people might then internalise this message – e.g.,  “I’m too damaged to be helped”, “no one can help me”, “what I went through was so awful that not even adults want to hear me talk about it”.

Related to this, we also discussed how important it is that professionals work alongside young people and consider their individual needs within their treatment plan. While young people may not always be able to label the psychological effects of their trauma, they are the expert in their own experience. We know that many young people in care have been let down by adults in their life (before care and in care) and might struggle with trust and relationships (this can be particularly true for those with PTSD). Building rapport is therefore very important.

Future work

There is much research to be done in the field of young people in care. Compared to research on the general population of young people, we are still far behind in what we know about the mental health needs of this groups. We all discussed the importance of moving this field forward with more large-scale projects, so that we can more strongly advocate for evidence-informed support for young people in care and care-leavers.

Just an opinion. Would it not be important to know if trauma occurred bc of one particular event versus a child that experienced events of trauma repeatedly. In the article it mentions that treatment would be the same for PTSD and complex PTSD bc treatment is in place for PTSD which is the same as complex PTSD. I disagree whole heartedly. Like regulating emotions first it’s important to name the correct emotion. When we experience emotions from trauma, it is also important to first name the emotion. Knowing every aspect of each trauma means to know each experience…which means knowing the individual person…which would possibly mean a different treatment.

I left care in 1983 after 10 years in a children’s home. Prior to that I experienced developmental trauma and neglect. After leaving the care home at 16 and care at 18 I was on my own. Unbeknown to me I was living with CPTSD. It wasn’t until I was in my early 50’s that I came across CPTSD. I have grappled with my early childhood experiences all my life in some way. I have been a mental health professional for 19 years. Most of my healing has not been from orthodox psychiatry. As Jennifer writes above it is the emotional part that needs to be fully felt to be able to heal. We need to grieve for the losses we experienced and feel the pain of the hurt child. We are holding the feelings that we could not understand and make sense of. We hid and repressed the hurt child away as it was to unsafe to be them. However we carried the unhealed part around which played out in our daily lives, replaying the early childhood trauma in adolescent and adult lives. Only when I fully felt the hurt, pain and grief did true healing begin to take place. The journey continues as I delve deeper into the part of me I never wanted and never wanted to be. Reclaiming that part has been difficult. We need to make friends with the part that we hated and despised for the things it did. I am more than happy to be contacted and to talk about my experiences.
