A new study published in Biological Psychiatry: Global Open Science provides compelling evidence that trauma exposure plays a critical role in the link between psychiatric family history and mental health struggles in adolescents. Led by Dr. Barbara Chaiyachati and a team of researchers at the Children’s Hospital of Philadelphia, the study emphasizes trauma as a “modifiable risk factor in youth,” drawing attention to the environmental, rather than purely genetic, dimensions of intergenerational mental health.
“[I]n a large cohort of American adolescents,” the authors write, “trauma is more common among youth with [family history] of psychiatric disorders, and that over 20% of the risk association between [family history] and adolescent general psychopathology is mediated through trauma exposure.”
By demonstrating that nearly a quarter of the link between psychiatric family history and adolescent mental health struggles is mediated by trauma exposure, the research disrupts assumptions that genetic inheritance is the primary engine of psychopathology. Instead, it highlights how social and relational injuries, often shaped by caregiving dynamics, structural inequality, and intergenerational stress, embed themselves in psychological development.

It annoys me that it keeps saying, “Not JUST genetics.” The fact that other family members have “diagnoses” does NOT imply a genetic cause! It could easily be that they were also traumatized by their own family/community growing up and simply did to others what was done to them.
Additionally, the definition of “trauma” in the study was EXTREMELY narrow! They did not include divorce, bullying, exposure to parental domestic abuse, or extreme poverty, just to name a few of many other traumatic events, and of course give zero credence to NEGLECT, which is probably far MORE common and possibly more damaging than overt abuse.
Despite this narrow definition, a quarter still had “trauma exposure” in their histories. Obviously, it is very common. The authors appear strongly biased toward believing a genetic basis is primary, but the study certainly does not show this to be the case.

Too much parental/family blame in the mental health system. Therapists ignored my autistic traits and turned everything into a false childhood trauma narrative to fit their confirmation bias. I’m an independent thinker not easily swayed by authority or social norms. I’m a deep thinker and more logical than emotional. I need explanations for everything. I have sensory issues. I get overwhelmed by too many demands at once in a world that expects multi-tasking. I say what I mean and mean what I say. I don’t need people twisting my words and reading more into them than what I’ve said. I have body language that is caused by sensory issues. My “fidgeting” and lack of eye contact does not mean I’m lying or filled with toxic shame caused by my parents. I needed tools for dealing with a world full of people very different from myself. Home was my safe space. Thankfully, my resistance to yield to authority figures prevented my buying into generational trauma narratives. I figured things out for myself with no real help from the mental health system, which is where the TRUE toxicity dwells.
