Brief eclectic psychotherapy for PTSD

1. Introduction

Version followed: the 16-session individual BEPP protocol of Berthold Gersons (Amsterdam; manual by Gersons, Carlier & Olff; English protocol 2011, distributed by Arq / the International BEPP Steering Group), as described by Gersons & Schnyder (2013), the Nijdam et al. (2012) trial and the APA guideline summary. The 70-page protocol itself is not drawn on; session contents below are reconstructed from these published descriptions. Where they differ, the difference is named.

Brief Eclectic Psychotherapy for PTSD (BEPP) is a protocolised, trauma-focused individual therapy for adults with PTSD. Gersons developed it in the 1980s, first for Dutch police officers after shooting incidents, and it is now used with a wide range of trauma populations [source: Gersons & Schnyder 2013; CEBC]. It is "eclectic" because it combines a modified CBT imaginal exposure, emotion-focused grief work, psychodynamic attention to meaning, childhood and the therapeutic relationship, directive writing tasks and memorabilia, and a closing farewell ritual [source: Gersons Vilnius 2017 slides; Arq Academy].

How change happens (the authors' model): PTSD is framed as a dysfunctional automatic fear response plus a loss of safety and trust. Change comes through two kinds of learning. (1) Implicit relearning: exposure lets suppressed emotions (grief, sorrow, anger, shame, guilt) be felt and expressed, which "resets" the fear signal. (2) Explicit relearning: in the "domain of meaning" phase the client works out how the trauma changed their view of self and world and leaves "sadder but wiser" rather than returning to a naive pre-trauma self [source: Gersons Vilnius 2017; Gersons & Schnyder 2013]. Gersons' theoretical sources are crisis theory, bereavement, psychodynamic theory, learning theory and the neurobiology of fear memory; these are the developer's claims [source: Vilnius 2017].

2. Framework

Format [source: APA guideline page; CEBC; Nijdam et al. 2012]: 16 individual sessions, 45–60 minutes, weekly (about 16 weeks). A partner or trusted person attends session 1 and the farewell ritual, and in the APA summary also the session-7 review. The Nijdam trial allowed the number of sessions to vary with recovery. Gersons stresses keeping to 16 sessions [source: Gersons & Schnyder 2013].

Indication [source: CEBC; APA; Nijdam et al. 2012]: adults with a PTSD diagnosis confirmed at a thorough intake. The APA page notes it was intended for single-event trauma. The Nijdam trial included PTSD from a single, ended event and allowed earlier trauma. Gersons reports clinical use with refugees, childhood-abuse survivors and complex PTSD [source: ISTSS Clinician's Corner; Gersons & Schnyder 2013].

Session sequence. Three published descriptions differ slightly, so all three are shown.

Phase	APA guideline summary	Gersons & Schnyder 2013	Nijdam et al. 2012 trial
Psychoeducation	Session 1, with support person; brief account of the event	Session 1, partner present; then revisited in every phase	Session 1
Relaxation + imaginal exposure	Sessions 2–6	About 5 sessions in total	Sessions 2–6
Memorabilia and letter writing	Within sessions 2–6 (letter as homework)	From about session 3, alongside exposure	Listed as components
Review	Session 7: progress and obstacles, with support person; adjust plan	Not described	Mid-treatment assessment after session 6
Domain of meaning / integration	Sessions 8–15	From about session 7, 6–10 sessions; less structured	Sessions 7–15 ("cognitive restructuring", giving meaning)
Farewell ritual	Session 16, plus relapse-prevention plan	Prepared from about session 13; ritual closes treatment	Session 16
Follow-up	Not stated	About 6 months after the end	Trial assessments

Phase goals:

Psychoeducation: client and partner understand symptoms as a consequence of the trauma, and the rationale is accepted [source: Vilnius 2017; CEBC].
Exposure, memorabilia and letters: access, feel and express the suppressed emotions until the memory no longer produces overwhelming emotion [source: Gersons & Schnyder 2013].
Domain of meaning: understand how the trauma changed self- and worldview, link it to biography, and establish selective new trust [source: Gersons & Schnyder 2013; CEBC programme goals].
Farewell ritual: leave the trauma behind without forgetting it, reunite with loved ones, end therapy [source: Gersons & Schnyder 2013].

Criteria for moving on:

Exposure ends when the whole event has been worked through part by part and it no longer evokes overwhelming emotion [source: Gersons & Schnyder 2013]. More exposure sessions are allowed if the client does not yet feel safe with the therapist, or if shame or guilt blocks expression [source: same].
The authors describe the shift to meaning as following on symptom decline: sleep improves, less energy goes to vigilance, and the client becomes curious about links with their past [source: ISTSS Clinician's Corner; CEBC].
At the end, the therapist checks that PTSD symptoms have actually decreased (checklists can help). If they have not, parts of the protocol are repeated [source: Gersons & Schnyder 2013].
A concrete numeric threshold for any transition was not found [uncertain].

Contraindications and exclusions:

Named by Gersons & Schnyder (2013): severe depression and psychosis. Trauma-related depression and substance use are not contraindications. Benzodiazepines are described as a handicap, because the client must be able to feel emotion; antidepressants are not a problem. (Any medication change is for the prescriber; no dosing given here.)
Exclusions in the Nijdam trial (research criteria, not necessarily clinical rules): acute suicidality, current severe major depression or severe substance dependence (eligible after initial treatment), lifetime psychotic disorder, severe personality disorder, and concurrent trauma-focused treatment.
CEBC says "relative contraindications" and comorbidity must be weighed at intake, and BEPP can be combined with group day treatment.
Added [synthesis]: current high dissociation, an ongoing threat or ongoing abuse, unstable housing or legal proceedings that need the client to stay defended, and no support person available (the protocol can still run, but adapt the partner elements).

Therapist requirements [source: CEBC; Nijdam 2012; Arq Academy]: licensed psychologist or psychiatrist trained in BEPP. CEBC lists 2.5-day training and supervision of the first 8 cases. Arq Academy runs a 2-day online course and recommends supervision afterwards. Gersons lists as competences: training in at least two evidence-based trauma treatments, compassionate listening that uses silence as an invitation, teaching about PTSD, tolerating harrowing stories, encouraging emotional outcry, and self-care with colleague support [source: Vilnius 2017].

3. Guiding principles

Emotion first, then learning. Practical meaning: do not hurry toward cognitive reframing; meaning work starts after grief, anger and shame have been expressed [source: Gersons & Schnyder 2013].
The target emotion is sorrow, not only fear. Practical meaning: in exposure, follow and invite sadness, grief, anger, shame and disgust rather than waiting for anxiety to habituate [source: ISTSS Clinician's Corner; Vilnius 2017].
Whole story, part by part. Practical meaning: across sessions, move through the entire sequence of events rather than repeating one moment until anxiety fades [source: Gersons & Schnyder 2013; Nijdam 2012].
Control before exposure. Practical meaning: a brief relaxation exercise precedes every exposure so the client feels some control and attention is focused [source: Vilnius 2017; ISTSS].
Psychoeducation is continuous. Practical meaning: open each session by reviewing the last one and symptom change, then explain this session's structure and why [source: Gersons & Schnyder 2013].
Involve the partner and family. Practical meaning: invite them to session 1 and the ritual; reframe irritability, sleep and family strain as trauma effects [source: Gersons & Schnyder 2013; CEBC].
"Sadder but wiser", not "as good as new". Practical meaning: aim for an accepted vulnerability and selective trust, not reassurance that the world is safe [source: Gersons & Schnyder 2013].
Accept some guilt and limits. Practical meaning: do not argue all guilt away; help the client hold realistic responsibility and human vulnerability [source: Gersons & Schnyder 2013].
Link the trauma to biography. Practical meaning: explore how childhood, norms, religion and prior relationships shaped the expectations the trauma shattered [source: Gersons & Schnyder 2013; Vilnius 2017].
Use the positive transference implicitly, and end on time. Practical meaning: the trusting relationship carries the work, but the 16-session limit and the ritual (also a farewell to the therapist) prevent drift into open-ended therapy [source: Vilnius 2017; Gersons & Schnyder 2013].
Pass the testing phase. Practical meaning: early on, clients check whether you can bear the details and know your field; show calm expertise and do not flinch [source: Gersons & Schnyder 2013].
Restore control and dignity. Practical meaning: letters and memorabilia give the client an active role, countering powerlessness and shame [source: ISTSS; Gersons & Schnyder 2013].
Stick to the protocol. Practical meaning: Gersons notes that therapists from CBT or EMDR backgrounds often drift; keep each session's predefined content [source: Gersons & Schnyder 2013].
Dose writing. Practical meaning: about 30 minutes a day and no more, to avoid overwhelm [source: Vilnius 2017; Gersons & Schnyder 2013].
Memories are the client's experience. Practical meaning: work with what the client remembers; never use relaxation or imagery to search for "hidden" memories [synthesis, per house rules].

4. Intervention inventory

BEPP has twelve parts in the published descriptions. Steps are written in my own words from the sources cited. Where a source gives only the component, the step-level detail is marked [synthesis]. The manual's own session scripts are not drawn on [uncertain].

4.1 Intake, indication and treatment agreement

Purpose / when: Before session 1, confirm that PTSD is the indication, weigh comorbidity and relative contraindications, and inform the client and family about the diagnosis and treatment [source: CEBC].
Steps:
1. Run a structured PTSD diagnostic assessment and a baseline symptom measure. The Nijdam trial used a clinician interview plus self-report; the Impact of Event Scale-Revised was one of its measures [source: Nijdam 2012].
2. Screen for severe depression, psychosis, acute suicidality, severe substance dependence and severe personality disorder; treat these first where needed [source: Gersons & Schnyder 2013; Nijdam 2012].
3. Review medication. Flag regular benzodiazepine use as likely to blunt emotional work and discuss it with the prescriber [source: Gersons & Schnyder 2013]. No dosing advice is given here.
4. Identify the index trauma, and ask who could attend session 1 and the ritual [source: CEBC].
5. Agree on 16 weekly sessions, the homework load and the ending date [synthesis from protocol structure].
Example language (illustrative): "This is a 16-session treatment with a clear structure. I'd like your partner, or someone you trust, to come to the first session."
Watch for: current threat or ongoing abuse, high dissociation, active suicidal intent. These need stabilisation or safety planning first [synthesis].

4.2 Psychoeducation with partner (session 1)

Purpose / when: Session 1. Help the client and partner see the symptoms as understandable effects of the trauma, and give the rationale [source: APA; CEBC; Gersons & Schnyder 2013].
Steps:
1. Welcome the client and partner, and explain the session's aim.
2. Ask the client for a brief, not detailed, account of what happened [source: APA].
3. Go through the PTSD symptoms one by one (intrusions, nightmares, avoidance, numbing, startle, sleep problems), linking each to the event [source: Vilnius 2017].
4. Explain PTSD as an automatic fear response that has stayed switched on, with lost control and lost trust in the world. Gersons contrasts the hyper-alertness to danger with ordinary forgetting of, for example, a shopping list: survival memory stays in focus, which helped at the time but disrupts daily life [source: ISTSS].
5. Ask the partner what they have noticed. Reframe irritability, withdrawal and sleep problems as trauma effects, and acknowledge the strain on partner and children [source: Gersons & Schnyder 2013; CEBC].
6. Explain the rationale: feel the held-back emotions, then learn from the experience, then close with a farewell ritual [source: Vilnius 2017].
7. Outline the course of treatment and homework (finding memorabilia, writing, preparing the ritual) [source: CEBC].
Example language (illustrative): "Your alarm system did its job during the event. It just hasn't switched off. The irritability your partner sees is part of that alarm, not who you are."
Watch for: relief, and "so I'm not going crazy" responses (working). Partner blame or hostility suggests a session-7 or separate couple conversation [synthesis]. Gersons notes that where public psychological knowledge is limited (e.g. some post-war or refugee settings), psychoeducation needs more sessions [source: ISTSS].

4.3 Session opening routine (every session from 2)

Purpose / when: Each session. Keeps psychoeducation continuous and the structure predictable [source: Gersons & Schnyder 2013].
Steps: (1) Review the previous session and homework. (2) Ask about symptom changes during the week (sleep, nightmares, intrusions, irritability). (3) Explain today's structure and why it comes now. (4) Proceed to the session component [source: Gersons & Schnyder 2013].
Example language (illustrative): "Before we start: how was the week after last session, and what happened with your sleep? Today we'll do the relaxation exercise, then continue the story from where we stopped."
Watch for: a temporary rise in intrusions after early exposure. Normalise it, and use it to decide the next segment [synthesis].

4.4 Brief relaxation exercise (before each exposure)

Purpose / when: Immediately before each imaginal exposure (sessions 2–6). It gives a sense of control and focuses attention [source: Vilnius 2017; ISTSS; Gersons & Schnyder 2013]. The APA page describes it as tensing and relaxing muscles.
Steps (my wording; the protocol's script is not drawn on):
1. The client sits comfortably, with eyes closed if willing.
2. Guide a few minutes of tensing then releasing major muscle groups in sequence (hands and arms, shoulders, face, legs), with slow breathing.
3. Keep it short. It is a gateway into exposure, not a stand-alone coping skill.
4. Move directly into the exposure while the client is settled.
Example language (illustrative): "Make a fist and hold the tension... and let it go. Notice the difference. Now the shoulders..."
Watch for: relaxation-induced anxiety, or drifting into sleep or numbness. If either happens, keep the eyes open and shorten the exercise [synthesis].

4.5 Imaginal exposure (sessions 2–6, about 4–6 sessions)

Purpose / when: Access, feel and express the suppressed emotions tied to the event, especially grief and sorrow, as well as fear, anger, shame and disgust, until the memory no longer overwhelms [source: Gersons & Schnyder 2013; ISTSS; CEBC].
Readiness: PTSD confirmed; no severe depression or psychosis; client stable enough to attend weekly; rationale accepted in session 1 [source: Gersons & Schnyder 2013]. Also added [synthesis]: the client can return to the present when asked, has no current danger, and has a basic plan for the hours after the session.
Dosing [source: Nijdam 2012; Gersons & Schnyder 2013]: about 15–20 minutes of uninterrupted exposure per session, within a 45–60 minute session. The event is split into parts that follow its chronological sequence, and one part is covered per session across roughly five sessions, until the whole event has been relived and its emotions experienced.
Steps:
1. Choose the starting point with the client. This is typically the beginning of the event, or just before it [synthesis].
2. After the relaxation exercise, with eyes closed, the client recounts that part of the event in the present tense, "as if it is happening now" [source: APA; Gersons & Schnyder 2013 for eyes closed].
3. Ask for very detailed sensory description of what they see, hear, smell and feel in the body, and what they think [source: Nijdam 2012 "sensory memories"; ISTSS "great detail"].
4. Go slowly. When emotion rises, especially sadness, stay with it and invite expression (crying, anger) rather than moving on [source: ISTSS; Vilnius 2017].
5. At the end of the 15–20 minutes, ask the client to open their eyes, then discuss what was experienced and felt. The sources mention a link between a "hot spot" of sadness, eyes opening and discussion; the exact rule (stop at the hot spot versus after the segment) could not be verified [uncertain].
6. Closure [synthesis]: orient the client to the room, rate current distress, name what was achieved, and agree the next segment.
7. Next session: continue from where you stopped, until the whole sequence is covered [source: Gersons & Schnyder 2013].
Example language (illustrative): "Close your eyes and go back to the moment you get out of the car. Tell me in the present tense: what do you see? ... What do you hear? ... What do you feel in your chest right now?" Then: "Let the sadness be there. You don't need to stop it." At the close: "Open your eyes. You're here with me in this room. What was the hardest moment just now?"
Watch for / working: emotional outcry followed by relief; fewer intrusions; easing tension and hypervigilance over the weeks; better sleep once emotions are "ventilated" [source: ISTSS; Gersons & Schnyder 2013]. Not working: a flat, factual report with no emotion (avoidance; see section 5), or rising dissociation.
Overwhelm / dissociation [synthesis]: open the eyes, switch to the past tense, ground the client (feet on the floor, name objects in the room, cool water), slow the pace, and resume with a smaller segment once the client is oriented. The sources say that when safety with the therapist or shame blocks emotion, more exposure sessions are allowed [source: Gersons & Schnyder 2013].
Variant: EMDR is sometimes used in place of or alongside imaginal exposure [source: ISTSS]. Gersons describes this as a variation; specifics were not found [uncertain].

4.6 Memorabilia (mementos)

Purpose / when: From about session 3, alongside exposure. Objects linked to the event stimulate memories and emotions [source: Gersons & Schnyder 2013; CEBC].
Steps:
1. Assign homework: look for objects connected to the trauma period, such as clothing worn at the time, photographs, newspaper clippings, or jewellery of a person who died [source: ISTSS; Gersons & Schnyder 2013; Nijdam 2012].
2. The client brings them to session. Invite them to hold and look at the object, describe it and what it brings back, and let the emotion come [source: Gersons & Schnyder 2013 "handling these objects"; step detail is synthesis].
3. Link the object to the exposure segment it belongs to.
4. Agree where the object will be kept until the farewell ritual, where it may be burned, buried or given another purpose [source: ISTSS; Vilnius 2017].
Example language (illustrative): "You brought the jacket. Take your time. Hold it and tell me what you notice and what comes back."
Watch for: reluctance to search for objects (avoidance, or genuine absence; either way, a photo of the place can substitute [synthesis]). Clients who hid clippings for years may feel shame when bringing them; acknowledge this [synthesis].

4.7 Writing assignment: the anger letter

Purpose / when: From the exposure phase onwards (APA: homework in sessions 2–6, "when relevant"). The letter lets the client express rage, aggression, sometimes hatred or wishes for harm, and guilt towards a person or organisation they hold responsible, "rationally or not". It restores self-respect and a sense of control, and reduces the shame of past powerlessness [source: Gersons & Schnyder 2013; Vilnius 2017; ISTSS].
Steps:
1. Explain: the letter is never sent and is kept for the farewell ritual; it should be uncensored, with no need to be fair or polite [source: Vilnius 2017; Gersons & Schnyder 2013].
2. Help choose the addressee, for example the perpetrator, an employer, the police service, insurers or authorities [source: Vilnius 2017 "organizations"; examples are synthesis].
3. Homework: write for about 30 minutes a day, and no longer, to avoid becoming overwhelmed [source: Vilnius 2017; Gersons & Schnyder 2013].
4. In session, the client reads parts aloud. The therapist focuses on the emotions as they arise, not on the wording or on correcting the facts [source: Vilnius 2017; Gersons & Schnyder 2013].
5. Continue writing over weeks until the anger has been fully expressed [source: Gersons & Schnyder 2013].
Example language (illustrative): "Nobody will ever read this except you, and me if you choose. Write exactly what you feel, as strongly as you feel it. Half an hour a day, then put it away." In session: "Read me the part that was hardest to write... What do you feel as you hear yourself say it?"
Watch for: letters that stay polite or factual (shame, or fear of one's own anger; validate the anger and invite stronger wording); writing far beyond 30 minutes, or rumination; any sign of intent to act on the anger or to send the letter. In that case, assess risk to others and revisit the rule that the letter stays private [synthesis].
Discrepancy: one summary of Gersons' ISTSS column describes a letter to someone who blames the client. The anger letter to whoever the client blames is the version consistently described in the other sources and is followed here [uncertain].

4.8 Farewell (goodbye) letter to a deceased person

Purpose / when: When the trauma involved a death. It expresses sadness, abandonment, memories and what was left unsaid, as part of mourning [source: Gersons & Schnyder 2013; Vilnius 2017; ISTSS].
Steps (step detail is synthesis): (1) Introduce it alongside or after the exposure of the death scene. (2) The client writes directly to the deceased: shared memories, what they miss, what they wish they had said, the goodbye they could not say. Same 30-minute daily limit. (3) Read aloud in session; stay with the grief. (4) Keep it for the ritual.
Example language (illustrative): "Write to him as if he could read it: what you remember, what you miss, what you never got to say."
Watch for: grief that remains intense and preoccupying beyond the trauma symptoms. The authors' traumatic-grief variant, BEP-TG (Smid et al. 2015), addresses this, but the paper is not drawn on [uncertain].

4.9 Mid-treatment review (session 7)

Purpose / when: Session 7, with the support person as appropriate: review progress and remaining obstacles, and adjust treatment [source: APA]. Gersons & Schnyder (2013) do not describe a separate review session; the Nijdam trial assessed after session 6.
Steps:
1. Re-measure symptoms and compare with baseline [synthesis, consistent with the trial's mid-term assessment].
2. Ask the client and partner what has changed in sleep, irritability and daily functioning.
3. Identify parts of the event not yet processed. Decide whether to add exposure sessions (allowed when safety or shame blocked emotion) or to move into the domain of meaning [source: Gersons & Schnyder 2013 for the extension rule].
Example language (illustrative): "Let's look at where we are. What's different at home? Is there any part of the story we haven't really gone through yet?"
Watch for: the partner's view often shows avoidance the client minimises [synthesis].

4.10 Domain of meaning and integration (about sessions 7/8–15)

Purpose / when: After the emotional work has reduced symptoms. The client explores how the trauma changed their view of self and world (trust in people, technology, nature), how earlier life shaped their reactions, and what they learned. The aim is to become "sadder but wiser" [source: Gersons & Schnyder 2013; ISTSS; Vilnius 2017]. The authors describe this phase as less structured and as demanding considerable therapist skill [source: Gersons & Schnyder 2013]. The Nijdam trial labelled it cognitive restructuring.
Themes to cover [source: Gersons & Schnyder 2013; Vilnius 2017; ISTSS]:
- Shattered assumptions: the lost "illusion of safety", replaced by realistic anticipation of risk.
- Changed view of self: vulnerability, guilt that sometimes must be accepted, and selective rather than blanket trust.
- Biography: how childhood experiences, past relationships, norms, values, religion, prejudice and work culture shaped expectations and the reaction to this event.
- Existential questions, and renewed appreciation of family, work, health and life as a "precious gift"; possible posttraumatic growth.
- Practical changes, for example returning to work.
Steps (sequencing is my synthesis from the themes):
1. Ask how the client saw themselves, others and the world before the event, and how they see them now.
2. Explore which of those beliefs the trauma broke, and where they came from (family, upbringing, profession).
3. Distinguish realistic guilt and responsibility from irrational self-blame. Help the client bear what is realistic rather than talking it away.
4. Explore what the client now values, and what they want to change in life and work.
5. Turn insights into concrete steps (work return, relationships, safety habits).
Example language (illustrative): "Before this happened, what did you take for granted about the world? ... And now? ... Where did you learn to expect that you'd always be in control?" Or: "Some of what you did that night you can't undo. What would it mean to carry that, rather than fight it?"
Watch for / working: the client talks with curiosity rather than distress, links the past to the event, and describes a more nuanced trust and new priorities. Not working: the client intellectualises without feeling (return to exposure or the letters), or new trauma memories emerge and need processing [synthesis].

4.11 Farewell ritual (prepared from about session 13; held at the end)

Purpose / when: Mark leaving the trauma behind without forgetting it, reunite with loved ones and return to normal life. Also a farewell to the therapist, which prevents needless extension of a strongly positive relationship [source: Gersons & Schnyder 2013; Vilnius 2017]. Gersons adapted the idea from Onno van der Hart's work on leave-taking rituals [source: Gersons & Schnyder 2013].
Steps:
1. From about session 13, the client designs their own ritual: what to do with the letters and memorabilia (burn, bury, or give them another purpose), where (a carefully chosen place), when, and with whom [source: Gersons & Schnyder 2013; Vilnius 2017; ISTSS].
2. Part 1, leave-taking: in the presence of the partner or loved ones, the client experiences the sadness once more and then lets go, for example by burning the letters. A little aggression towards trauma-related objects is acceptable [source: ISTSS; Gersons & Schnyder 2013]. One reported example: a bombing survivor burned photos of himself leaving the station [source: Gersons & Schnyder 2013].
3. Part 2, celebration: reunion with significant others, for example a family dinner or party [source: Vilnius 2017; Gersons & Schnyder 2013].
4. The therapist usually does not attend. The partner is present, and sometimes the children [source: Gersons & Schnyder 2013; CEBC].
5. In the final session, review how the ritual went [synthesis; the APA summary places the ritual at session 16 itself].
Example language (illustrative): "This ritual is yours to design. What would mark, for you, that this period is over? Who do you want with you, and what do you want to do with the letters?"
Safety [synthesis]: plan fire use lawfully and safely; don't destroy items others may need (e.g. legal evidence or shared family property) without agreement.
Watch for: reluctance to part with objects (it may be grief, or unfinished processing; it is fine to keep some objects "for another purpose" [source: ISTSS]); a ritual planned without loved ones (explore isolation).

4.12 Ending: symptom check, relapse prevention and follow-up

Purpose / when: Final session(s). Confirm improvement and plan ahead [source: Gersons & Schnyder 2013; APA].
Steps:
1. Check that PTSD symptoms have actually decreased, using checklists if helpful. If they have not, repeat parts of the protocol (e.g. extra exposure) [source: Gersons & Schnyder 2013].
2. Build a relapse-prevention plan [source: APA]. Its contents are not specified in the sources; suggested [synthesis]: personal warning signs, triggers such as anniversaries and court dates, what helped, and when to call back.
3. Schedule follow-up about 6 months later [source: Gersons & Schnyder 2013].
Example language (illustrative): "Anniversaries can stir things up again. That isn't relapse. Here's what we agreed you'll do if the nightmares come back for more than a couple of weeks."

4.13 Adaptations named by the developers

Traumatic grief: BEP-TG (Smid et al. 2015) [uncertain].
Children: a child version in development [source: ISTSS].
Narrative-oriented, post-war or low-literacy settings: more sessions, especially for psychoeducation; Gersons notes the similarity to Narrative Exposure Therapy [source: ISTSS].
Group day treatment: BEPP can be combined with a group day-treatment programme [source: CEBC].
Languages: the protocol is available in several languages (Arq lists English, Spanish, German, Italian, Polish, Dutch, Georgian, Lithuanian and Korean) [source: Arq Academy].

5. Handling problems

The sources address only a few problems directly (marked with a source). Everything else is my own synthesis.

Emotion does not come (a flat, factual account). The authors name two causes: the client does not yet feel safe with the therapist, or shame or guilt blocks expression. Their response is to take more exposure sessions [source: Gersons & Schnyder 2013]. Concretely [synthesis]: slow down; ask for sensory detail at the moment just before the worst part; bring in a memento; ask "What are you not letting yourself feel right now?"; name shame directly and normalise it.
The testing phase. Early on, clients check whether the therapist can bear the details and is truly expert [source: Gersons & Schnyder 2013]. Response [synthesis]: ask for the worst details calmly, show no visible shock, and explain the rationale with confidence.
Therapist avoidance or fear of graphic detail and intense grief. The authors note that both therapists and clients may fear this phase, and that improvement often follows enduring it [source: ISTSS]. Response: supervision, peer support and self-care are listed as therapist competences [source: Vilnius 2017]. Notice whether you change the subject when the client cries [synthesis].
Protocol drift. Therapists trained in CBT or EMDR often drift [source: Gersons & Schnyder 2013]. Response [synthesis]: check each session against the planned component, and use the fidelity points the trial rated (sessions 1, 2, 4, 11, 13, 15) [source: Nijdam 2012] for self-audit or supervision.
Drop-out during the exposure phase. In the Nijdam trial, dropouts clustered around sessions 4–8, among clients with higher symptom scores [source: Nijdam 2012]. Response [synthesis]: predict a temporary symptom rise at session 1; check in by phone after early exposure sessions; involve the partner in encouragement; do not reduce exposure to near zero, but shorten segments.
Overwhelm or dissociation in exposure [synthesis]. Open the eyes; ground the client in the present (orientation to date, place and the therapist; feet on the floor; sensory anchors); change to the past tense; resume with a smaller segment. If dissociation is repeated, reassess for a dissociative presentation and consider a stabilisation phase before continuing. Never push for "more memory": work with what is remembered, and do not use relaxation or imagery to uncover memories.
Distress after the session [synthesis]. End with orientation and a distress check; agree on an evening plan (partner informed, a calming activity, no alcohol to cope); give contact details for crisis services.
Homework non-adherence (letters, memorabilia) [synthesis]. Explore avoidance versus practical barriers; write the first lines together in session; allow typing or voice notes; keep the 30-minute daily ceiling, which itself can reduce fear of being swamped [source for the ceiling: Vilnius 2017].
Anger escalating into threat [synthesis]. If the anger letter turns into plans to confront or harm, pause the writing, assess risk to others, follow your duty-to-warn and safeguarding rules, and restate that the letter is never sent.
Suicidal thoughts or severe depression emerging [synthesis]. Severe depression is a contraindication [source: Gersons & Schnyder 2013]. Assess risk with standard practice, make a safety plan including lethal-means counselling (safe storage and removal), and suspend exposure until stable.
Benzodiazepines blunting the work. The authors see them as a handicap [source: Gersons & Schnyder 2013]. Response [synthesis]: discuss with the prescriber; never advise stopping abruptly.
Symptoms not improved at the end. Repeat parts of the protocol [source: Gersons & Schnyder 2013]. If there is still no response, consider another evidence-based trauma treatment (e.g. EMDR, which matched BEPP in the Nijdam trial) [synthesis].
Rupture or idealisation. Gersons notes the strong positive transference, and that the ritual also says goodbye to the therapist [source: Gersons & Schnyder 2013]. Responses [synthesis]: if a rupture occurs (e.g. after pushing exposure too hard), name it, take your share, and adjust the pace without abandoning the protocol. If the client asks for open-ended continuation, hold the 16-session frame and use the ritual to work through the ending.
Partner unavailable, unsupportive or part of the problem [synthesis]. Invite another trusted person. If the partner is abusive or the relationship is the trauma context, do not involve them, and assess safety.
Client wants to keep memorabilia or refuses to burn letters. Burying, or giving objects another purpose, is an accepted option [source: ISTSS]. Explore the meaning of keeping them [synthesis].
Meaning phase stays intellectual, or new traumas surface [synthesis]. Return briefly to exposure or the letters for the newly surfaced material, within the session limit; if earlier traumas dominate, consider a separate treatment episode after BEPP.
Cultural or low-literacy contexts. Add psychoeducation sessions [source: ISTSS]. Allow oral "letters" recorded or dictated, and adapt the ritual to the client's cultural and religious practices [synthesis].
Grief dominates. Use the farewell letter. Consider the BEP-TG variant (Smid et al. 2015) [uncertain].
