From stress to trauma: one mechanism, one spectrum

The diagnostic categories this paper invokes — stress, anxiety, burnout, depression, PTSD, Complex PTSD — are neither well-defined nor mutually exclusive.

Stress carries no ICD or DSM classification. It is used simultaneously for the stimulus, the response, and the biological mechanism. Anxiety is a clinical category but is also used loosely for normal stress responses. PTSD was reclassified out of the anxiety disorders in DSM-5, itself an acknowledgement that the category was inadequate. Burnout is classified by the WHO as an occupational phenomenon rather than a medical condition, and is associated with hospitalisation, disease, and premature death.

The scholarly literature acknowledges the instability explicitly. Bianchi, Schonfeld, and Laurent (2015) concluded that the distinction between burnout and depression is conceptually fragile. Kotov, Krueger, Watson and colleagues (2017) established empirically that PTSD, depression, and anxiety exist on a continuum with normal-range functioning, grouped by shared patterns of negative emotionality rather than by distinct causes.

There are no categorically distinct conditions, but expressions of one continuous process that the diagnostic system divides at particular severity thresholds. The categories are measurement conveniences.

Robert maps that spectrum from inside it, and his sequence is more precise than the diagnostic one. First the low hum of never knowing when the scrutiny will swing round. Then the numbing: armour that goes on to stop the disappointments landing, and shuts out everything else with them. Then what he calls the smoulder: a slow turning to ash, grey and still upright, running on fumes for years, with no single dramatic collapse to point to. Then shame, which seals the whole thing in silence. Then moral injury, the daily wear of being made to do things he could not square with who he was. And at the far end, what he names as anxious depression and workplace PTSD, with almost as long spent recovering from it as the career itself lasted.

The absence of a collapse to point to follows from the architecture: nothing was required, so nothing was breached, and nothing happened on a date. A harm that produces no event produces no moment at which the person can say: that is when it happened. It produces years of grey, and shame that there is nothing to show for it.

Robert works out the consequence himself. A dramatic collapse forces acknowledgement. It makes the problem visible, demands a plan, and brings other people round to help. The slow version leaves room for doubt, grounds for denial, and a downplaying of the severity. And because it happened gradually, the person concludes it cannot be that serious. He ran that doubt on himself for years, putting the tiredness, the loss of enthusiasm and the growing cynicism down to the normal stress of a management position and his own stage of life and career. Decades on, with the diagnosis long behind him, he still checks whether he is being overly dramatic; the conditioning, he says, goes deep.

And the recognition arrives out of order. By the time the third employer ended, he was, in his own account, completely numb, and does not really remember the following year. He describes his body and his unconscious deciding it was three strikes and out, and the rest of his brain taking a long time to catch on. The record had been running long before that: disturbed sleep and the first signs of irritable bowel syndrome, through years he had no other name for. The body keeps the score. Van der Kolk (2014), writing a book under that title, sets out the clinical case that traumatic experience is held in the body and in systems that run below speech, and that the physical complaints arrive whether or not the person can say what happened to them. Read through DFS, the body’s is the only account being kept because the architecture produced no event: nothing happened on a date, so there was nothing for the words to attach to. That is what an accumulating harm without events does: it is counted somewhere, but not anywhere the person can reach.

The naming runs late in the same way. He left the first employer after fifteen years, having watched a project he had worked on trashed, in his words, for no good reason, and thinking that what he felt about it was disillusionment and frustration. Those are the words an ordinary poor job supplies. What he was carrying, by his own later account, was heartbreak, a sense of having been betrayed and abused, and shame at having let it happen to him. That last one is the failure attributed to the person for what the structure produced, running on a whole career rather than on a single outcome. Fifteen years had produced no event, so they produced no name, and the nearest name available was much too small.

The DFS claim does not depend on the diagnostic categories being stable. This paper has argued, by mechanism and not by measurement, that the far end of this spectrum is reachable without a hostile act. The weaker claim holds regardless of whether that argument is accepted: HDM, inside an ordinary employment relationship, creates the structural conditions Herman identified as the mechanism of psychological trauma, and those conditions produce harm along a spectrum. On that spectrum burnout is the most organisationally prevalent, most WHO-endorsed, and most structurally attributable point. If an organisation accepts that it produces burnout, it has accepted that it is producing harm via the same mechanism that, at greater intensity and duration, produces clinical outcomes.
