Clinical picture. M., a man in his late thirties, presented eight months after a serious road accident with recurrent nightmares, persistent hypervigilance while driving, and a firm conviction that he had "permanently lost his nerve." He had stopped using motorways entirely and kept the radio off to avoid any sound that might trigger an image. In session, the clinician introduced the psychoeducational worksheet on what keeps PTSD going, walking through the four-petal loop and naming each cycle M. recognised in his own week. M. noted, with some relief, that the diagram reframed his avoidance not as rational self-protection but as the mechanism that was preventing the memory from receiving a time stamp. He left the session with a modest agreed task: to observe one avoidance move per day without acting on it, as a first step toward tolerating proximity to the material.
What Keeps PTSD Going: PDF Worksheet, Tools and Exercises
A visual fiche PDF mapping the three interlocking cycles that sustain PTSD, with tools and exercises clinicians can use to explain maintenance in session.
Clinical vignettes
Avoidance Sustaining Intrusions After a Road Accident
Threatening Beliefs Amplifying Flashback Distress
Clinical picture. A., a woman in her mid-forties referred following prolonged interpersonal trauma, reported that her flashbacks frightened her less for their content than for what she believed they meant: she was convinced that experiencing them proved she was "going mad." This secondary layer of fear was sustaining a cycle of internal avoidance, numbing, and renewed intrusions. The clinician used the worksheet to distinguish the first-order intrusion from the second-order belief about the intrusion, pointing to the relevant section on how believing flashbacks signal breakdown adds fear on top of fear. A. identified this pattern as one she had never articulated before and described a small but meaningful reduction in the urgency she felt during the following week's intrusions. The exchange opened space for subsequent work on belief restructuring without requiring A. to revisit the trauma content prematurely.
Explaining why PTSD persists long after the triggering event is one of the most clinically useful things you can do in early sessions, and one of the most reliably misunderstood concepts when delivered verbally alone. Patients hear "avoidance maintains the problem" and reach either self-blame or abstraction. This fiche PDF puts the maintenance model on paper in a form that holds up between sessions.

Why PTSD maintenance resists verbal explanation
The core phenomenological feature of PTSD, the sense of present danger long after the event has ended, is hard to name without sounding circular. Patients grasp hyperarousal and intrusions as symptoms; what they rarely see without support is how these same symptoms function as maintaining processes. The secondary appraisal layer compounds this: a flashback becomes evidence of being broken rather than evidence of an unprocessed memory, which adds fear on top of fear and deepens the very loops you are trying to dismantle.
The Ehlers and Clark (2000) cognitive model maps exactly this architecture, and the Ehlers and Clark PTSD model fiche makes the theoretical structure available to clinicians who need more depth. But walking through the model verbally, section by section, loses most patients before the third cycle. Without a shared visual anchor, the psychoeducation dissolves quickly.
Inside the fiche: the vicious flower and three cycles
The fiche opens with the "vicious flower" diagram: four petals labeled intrusions, threatening beliefs, avoidance, and hyperarousal, all feeding a central hub titled sense of present danger. The layout does something a verbal description cannot: it shows the circular logic in a single glance, making clear that each petal feeds the centre and the centre feeds every petal back.
Section two develops the three cycles in precise but accessible language.
- Unprocessed memories: stored without a time stamp, arriving as "this is happening now" rather than "this happened then." The fiche links this directly to why trauma memories have specific properties that ordinary memories do not.
- Threatening beliefs: common conclusions listed include "It was my fault" and "I am permanently damaged." The fiche names the second layer explicitly: believing that flashbacks mean you are losing your mind adds fear on top of fear.
- Avoidance and safety behaviors: external (places, people, news) and internal (numbing, scrolling, dissociating) strategies, labeled with a phrase worth quoting to patients: "short relief, long glue." This connects directly to work on safety behaviors in anxiety and confronting avoidance patterns.
Section three maps a direction out of each cycle: narrative processing for memories, evidence-testing for beliefs, graduated release of safety behaviors for avoidance. A final "Things worth holding" block contains five reframing statements that directly counter the most common maladaptive conclusions ("Avoidance is not cowardice," "Recovery is not forgetting," "Feeling is not re-living").
> Key takeaway: The fiche is a visual support that facilitates the explanation of PTSD maintenance in session. It is not a self-help checklist the patient completes alone; it is a shared diagram the clinician uses to make the why-it-persists question concrete, and a reference the patient takes home.
A closing "To discuss in session" block offers three ready-to-use clinical prompts, including: "Which threatening belief about yourself or the world feels the most stuck right now, and what evidence from today might gently challenge it?" These are not homework questions; they are debrief conversation starters built into the fiche itself.

Access all the toolsWhen and how to introduce it
The fiche fits naturally in the psychoeducation phase, typically sessions two to four, once the initial anamnesis has established a symptom profile and the therapeutic alliance can hold a formulation conversation. It pairs well with common reactions to trauma, with how PTSD affects memory and retrieval, and with the stimulus discrimination exercise for patients who need concrete tools to distinguish then from now.
Particularly useful profiles: patients who intellectualize their symptoms without connecting them to a coherent system; patients who interpret persistent intrusions as evidence of being "unfixable"; patients demoralized by repeated willpower-based recovery attempts. For patients with active dissociation or severe destabilization, hold the fiche until stabilization is sufficient. If complex trauma is the clinical picture, Complex PTSD resources provide a useful complement before introducing a maintenance model.
A simple framing: "I want to show you a diagram that maps how PTSD tends to keep itself going. It's not a verdict on you; it's a description of a system. Let's look at it together." After presenting the diagram, anchor the debrief in the patient's own recent examples: which cycle fired most this week, which safety behavior feels most entrenched. The fiche's three discussion prompts guide this naturally.
For patients moving into active intervention, intrusive thoughts tools and the PTSD treatment blueprint extend the work the fiche begins. The fiche does not replace clinical formulation; it makes the formulation visible, portable, and debriefable.
