When Trauma Won’t Quit: Understanding Complex PTSD

The current accepted diagnosis for experiencing a single traumatic life event is posttraumatic stress (PTSD). In diagnosing posttraumatic stress, clinicians must see that the person experienced a traumatic life event in which they were involved in or witnessed events where death or serious injury was threatened or there was a threat to physical integrity of self or others (D’Andrea, Ford, Bradley, Spinazzola, & van der Kolk, 2012). But trauma can be more complicated than that.

Discussed in the clinical research is another form of posttraumatic stress, appropriately called complex posttraumatic stress. Herman (1992) defines complex PTSD as “typically the result of exposure to repeated or prolonged instances or multiple forms of interpersonal trauma, often occurring under circumstances where escape is not possible due to physical, psychological, maturational, family/environmental, or social constraints.”

So what are some of the situations in which someone is exposed to interpersonal trauma, and what are the short- and long-term consequences of someone experiencing this kind of trauma? Felitti, et al. (1998) describes several abuses and household dysfunctions by parents or other adults in the home in which interpersonal trauma can occur. These include:


  • Psychological abuse: Repeated insults, negative comments, and swearing directed at the victim.
  • Physical abuse: When a parent or some other adult in the household repeatedly pushes, grabs, slaps, or hits the victim, and marks are often left.
  • Sexual abuse: When a parent or some other adult in the household repeatedly touches, fondles, or grabs the victim in a sexual way. When a child is forced to have intercourse with a parent or adult.

Household Dysfunctions

  • Substance abuse: When a parent or other adult in the home can be described as having a problem with drugs or alcohol.
  • Mental health issues: When a parent or other adult in the house can be described as having depression or another serious mental condition.
  • Mother treated violently: When the mother in the household is physically abused. The mother is repeatedly pushed, grabbed, and slapped, and it is witnessed by the victim.
  • Criminal behavior in the household: When someone in the home participates in an illegal activity or is arrested and sent to prison.
  • Bullying, neglect, betrayal: If a person is bullied, neglected, or betrayed by a loved one, this can cause interpersonal trauma (D’Andrea, et al., 2012).

When a person experiences any of the above, there can be many adverse effects. Studies show children who are repeatedly exposed to these abuses may experience severe coexisting problems with emotion regulation, impulse control, attention, and cognition, as well as interpersonal relationships and negative self-attributions (D’Andrea, et al., 2012).

Despite evidence to suggest interpersonal trauma results in complex posttraumatic stress and has both short- and long-term adverse health outcomes, the mental health community is still struggling to develop a diagnosis to capture this exposure and condition.

One of the most cited studies on this subject found that the more times a child was exposed to these abuses, the greater the likelihood they experienced severe health problems in adulthood. The study found a strong relationship between the number of adverse childhood exposures and the following conditions: heart disease, cancer, chronic bronchitis or emphysema, history of hepatitis or jaundice, skeletal fractures, and poor self-rated health (Felitti, et al., 1998).

In addition, parents who have experienced trauma and do not seek treatment can unknowingly externalize their trauma and pass it on to their child’s developing personality, a process known as transgenerational transmission (Shulevitz, 2014).

Because of the impact interpersonal trauma can have on health and well-being, seeking treatment is critical. Effective treatments for exposure to interpersonal trauma may include:

  • Prolonged exposure therapy: This treatment is supported by over 20 years of research and is highly effective for treating chronic posttraumatic stress and associated symptoms. The goal of exposure therapy is to address traumatic memories and triggers. The therapist works with the person to address these elements gradually so a tolerance to the memory is built over time (Foa, Hernbree, and Rothbaum, 2007).
  • Eye movement desensitization and reprocessing: Otherwise known as EMDR, this treatment is also supported by over 20 years of research. By engaging the brain in dual attention stimulus (DAS) and left-to-right brain stimulation, the goal of this approach is for the person to access the memory; recall specific aspects of the memory; and reprocess the memory so it is stored in an adaptive form. The clinician helps the person to see the event in a different way—perhaps a source of strength or something that took courage to survive (Shapiro, 2001).
  • Cognitive behavioral therapy: CBT is an approach that targets automatic negative thoughts and core beliefs about the self. People who experience interpersonal trauma often have more negative beliefs and attributions about themselves that are not true (D’Andrea, et al. 2012). Using exercises such as thought records and data logs, the clinician helps the person to examine their thoughts and understand they might be unbalanced. By finding evidence for and against their negative thoughts, the person is able to create alternative and more balanced thought patterns about themselves (Greenberger and Padesky, 1995).

Despite evidence to suggest interpersonal trauma results in complex posttraumatic stress and has both short- and long-term adverse health outcomes, the mental health community is still struggling to develop a diagnosis to capture this exposure and condition. Several task forces have been created to address the need for a consensus on how to diagnose and treat people affected by interpersonal trauma. Until then, complex posttraumatic stress will remain a notable omission from the Diagnostic and Statistical Manual of Mental Disorders (DSM).

If you or a loved one has been exposed to any of the above-mentioned abuses, seek help from a licensed and trained mental health professional.

  1. I was physically, emotionally, verbally, and medically abused by my mother for over 27 years. My father stood by, supported her, and neglected me all the while. I also had a somewhat abusive younger sister, and I was also heavily sexualized by my mom and was nearly raped at 14 because of her ( a situation she intentionally put me in). By the time I was 27, I was on at least 7 different antipsychotic medications ( my mom was a nurse and had very close relationships with my Drs). I eventually broke away, god knows how, got off the meds, and away from my mother. I was promptly disowned by my father. He told me if I didn’t come back and admit I was sick, he’d never talk to me again. It’s been 3 years since I’ve seen my mom or my sister, and 2 since I’ve seen him. I’m off the meds, have a decent job I do very well at, have been through a day hospital, seen crisis counselors and therapists to help get me on my feet and understand what happened. I even have an apartment of my own in a little down town. I am nice and sweet and funny and smart. But mostly I am so full of pain. I don’t fear much ( except my mother), but I am horribly fearful of remaining alone, and never finding a family; friendship, married or otherwise. Intellectually I know it wasn’t me , but spiritually and emotionally it’s a different story. I can’t connect with people, I don’t know how to be myself without pushing them away. I ache to be loved but don’t know how to find it, or if I ever will. Mostly I just want to be held. I recently started with a new therapist, and am on a light anxiety med and depression med and mood stabilizer. Triggers are everywhere, especially in stories/shows about loving families. Nightmares are nightly, and panic attacks almost daily. I don’t know what to do. I know I have complex PTSD, and likely Stockholm syndrome (especially with my dad) that seems to be transferred to any other relationship I try to form. I can’t research or fight my way out of this, and time can only do so much before it’s gone. If you have any resources, words of hope our guidance, I would be so grateful.


    • Hi Jess thank you for getting in contact. I am so sorry to read of your terrible childhood. You are a really brave survivor and must be very resilient to achieve so much with your life. It is so good that you have a therapist. Hopefully she is a good one. I would really recommend reading The Body Keeps The Score” – Bessel Van Der Kolk. It is fantastic for anyone who has experienced trauma such as yours. It is written in an accessible way. It is available on Amazon.

      It is fantastic that you have cut ties with your family. That is the healthiest thing you could have done for yourself. I understand you still have feelings for your mother. If you want to know more about Stockholm Syndrome just type it into the search engine on my blog and you will find information on it there. I experience it too so understand how difficult it is. I can promise with therapy and time this will get better. The symptoms of your Complex PTSD will become more manageable and you will learn once again to function socially and not find events around families so triggering.

      I take Clonidine for my nightmares and flashbacks and it works very effectively. I also am on a mood stabiliser and a anti depressant. I am stable at the moment and life has improved. I promise if you work hard it will for you too. All the best Erin.

  2. You did a great job explaining why CPTSD is not yet in the DSM. It’s a very important disorder that is not getting attention because of its omission in the manual, yet it’s only omitted because of its complex nature which many professionals feel begs to be studied in depth. Good post. Even with all your sources, I did not feel choked by their number. You integrated then into the piece wonderfully and non-overwhelmingly! ❤

    • Morning. Thank you for your comments. Much appreciated. It is very frustrating that CPTSD is not included in the DSM as it means many sufferers go undiagnosed which is terrible for them. I was lucky and my psychiatrist specialises in it so was able to spot all the signs. He has been immensely helpful. I wish the same for others. All the best Erin

I would love to hear from you so please leave a comment. All feedback is much appreciated. Thank you. Erin
