Persuasion therapy

1. Introduction

Version followed: Paul Dubois's "rational psychotherapy" / persuasion method as set out in Les psychonévroses et leur traitement moral (1904; English: The Psychic Treatment of Nervous Disorders, trans. Jelliffe & White, Funk & Wagnalls, scan of the 1907/1909 revised edition), supplemented by his De l'influence de l'esprit sur le corps (9th ed., Bern, c. 1910), Self-Control and How to Secure It (1909) and Reason and Sentiment (1911). Déjerine & Gauckler's The Psychoneuroses and Their Treatment by Psychotherapy (Engl. 2nd ed., 1913/1915) is given as a named variant ("Déjerine variant") wherever it departs from Dubois.

What it is. Persuasion therapy (also "moral treatment of the psychoneuroses", "rational psychotherapy", Persuasionsmethode) was a physician-delivered talking treatment for what were then called neurasthenia, psychasthenia, hysteria, hypochondria and functional (psychosomatic) complaints. It was developed by the Bern neuropathologist Paul Dubois (1848–1918) around 1900 and, in a modified, emotion-centred form, by Jules Déjerine (1849–1917) at the Salpêtrière. It is a historical precursor, not a current manualised therapy: there is no treatment manual, no training body and no fixed protocol. What follows reconstructs the clinical procedures its authors describe and translates them, where flagged [synthesis], into outpatient psychotherapy language. [source: Wikipedia, Paul Charles Dubois; Ärzteblatt, "Paul Dubois (1848–1918) Pionier der Psychotherapie"; Dubois 1904/1907, front matter]

Core idea of change. Dubois held that functional symptoms are produced and amplified by the patient's own ideas: fearful expectation, anxious attention to bodily sensations and discouraged self-judgements (in his phrase, negative autosuggestion). Change happens when the physician, in frank, friendly conversation, convinces the patient by reasons the physician genuinely holds (persuasion, not suggestion) that the symptoms are functional, understandable and curable, and then re-educates the patient's judgement and character so that reason, not fear, governs feeling and action. In his model every action runs "mental representation, sentiment, action" (Reason and Sentiment, p. 36), so feelings are changed by testing the ideas beneath them. Déjerine agreed on the goal but held that ideas alone do not move patients: change comes through the emotional confidence the patient places in the physician, within which explanation and re-education can work. [source: Dubois 1904/1907 pp. viii–xv; Dubois 1911 pp. 27–48; Déjerine & Gauckler 1913 pp. v–viii; Robertson 2013]

2. Framework

Neither Dubois nor Déjerine sets out numbered phases. The sequence below is reconstructed from their descriptions of practice and from the chapter order of their treatment sections; the phase labels and transition criteria are [synthesis]. Chapters XVII–XIX of Dubois ("Therapeutics of the psychoneuroses", "Rational psychotherapy", "Weir Mitchell's treatment and needed modifications") and Part III of Déjerine & Gauckler (Ch. XIX–XXVII) were identified from the tables of contents but their full text is not drawn on here; details attributed to them are marked [uncertain].

Format in the original. Individual physician–patient talks. Dubois worked mainly as an office and home-visit physician in Bern and admitted selected patients to a clinic stay, for which they agreed in advance to roughly a month without visitors, a darkened room and a strict diet; he wrote long follow-up letters to patients between and after meetings. Déjerine ran an isolation-and-psychotherapy ward at the Salpêtrière (the Salle Pinel) with interns and nurses, used for about fifteen years and several thousand patients. Duration: Dubois reports patients who changed their outlook often recovered sleep and appetite "in a few days, almost always in a few weeks" (De l'influence, p. 85, paraphrased from French); Déjerine says the process "often requires a long time" (p. vi). [source: Rosenfluh 2006; Déjerine & Gauckler 1913 pp. vi–vii; Mazet 2017]

Modern outpatient format [synthesis]: weekly (or, early on, twice-weekly) 50-minute individual sessions, roughly 8–20 sessions, with brief written summaries or letters between sessions in place of Dubois's correspondence. No isolation, enforced rest or dietary regime (see 4.17).

Phase A: Examination and diagnosis

Goal: establish that the complaints are functional, gain the authority to say so honestly, and map the patient's "mentality" (fears, habits of attention, moral judgements).
Original: a thorough medical examination by the treating physician, then analysis and classification of the patient's psychology (Dubois p. xii; Déjerine Ch. XX "The Examination and Questioning of the Neuropath" [uncertain]).
Modern: the psychotherapist secures (or confirms) an adequate medical work-up from a physician before treating any bodily symptom as functional [synthesis].
Move on when organic disease has been reasonably excluded or is being managed in parallel, and the patient has told their full story [synthesis].

Phase B: Confidence and explanation

Goal: an intimate, friendly relationship and a shared understanding of how the symptoms arose and how they can go.
Dubois: "an intimate friendly conversation" (p. ix); showing the patient that their mentality plays a large part in the illness (p. viii). Déjerine: the physician explains "how and why he fell ill, and how and why he can become cured" (p. vi); patients get well only once they trust the physician (p. vii).
Move on when the patient can restate the explanation in their own words and voices at least provisional hope of recovery [synthesis].

Phase C: Persuasion and re-education of judgement

Goal: dismantle the specific fearful or discouraged ideas, and replace attention to symptoms with indifference and normal activity.
Dubois: Socratic dialogue and reasoned argument; sentiments are submitted to the criticism of reason (Reason and Sentiment p. 45); patients learn to say "it is nothing, it will pass" and to resume normal eating, sleep habits and duties (De l'influence pp. 51, 70–73).
Move on when symptoms are falling and the patient is resuming normal activity without needing constant reassurance [synthesis].

Phase D: Moral education and self-education

Goal: durable change in character: reflection before acting, tolerance of self and others, moderation, courage, altruism.
Dubois: Self-Control (chapter topics: thought, the act, conscience, meditation, tolerance, indulgence, patience, courage); "temperament made into character" through reasoned self-education (De l'influence p. 84).
Move on (to ending) when the patient applies the principles independently to new difficulties [synthesis].

Phase E: Follow-up

Original: letters and occasional consultations (Rosenfluh 2006). Modern: spaced booster sessions [synthesis].

3. Guiding principles

Persuade, never suggest. Use only arguments you yourself believe; Dubois rejects suggestion because it bypasses reason and calls a stock reassuring formula "a professional lie" (p. x). Practical meaning: no scripted reassurance, no techniques that work by the patient not noticing them. [source: Dubois 1904/1907 pp. ix–x]
Address the reason. The patient is reached through intellect and judgement; the aim is conviction, not compliance ("authority is decidedly not a rational means", Reason and Sentiment p. 38). Practical meaning: explain, argue, invite objection; do not order. [source: Dubois 1911; Wikipedia]
The symptoms are real. "Il n'y a pas de malades imaginaires; ils souffrent tous" (there are no imaginary patients; they all suffer) (De l'influence p. 50). Practical meaning: never imply the patient is inventing or exaggerating. [source: Dubois c. 1910]
Fear is the core. "The primordial failing of all these psychasthenics is fear" (p. viii). Practical meaning: in every formulation, look for the fear driving the attention and the avoidance. [source: Dubois 1904/1907]
Attention and expectation shape bodily experience. Anxious, expectant attention makes sensations vivid; turning attention away lets them fade (De l'influence pp. 31–36, 70, 74). Practical meaning: target symptom-monitoring and anticipation, not just the symptom. [source: Dubois c. 1910]
Treat the mentality, not just the symptom. Dubois would rather understand the patient's route to a symptom than remove it quickly (p. x); Déjerine criticised therapy aimed "only to the symptom, and not to the cause" (p. vi). Practical meaning: every symptom-level intervention is tied back to the underlying attitude. [source: Dubois 1904/1907; Déjerine & Gauckler 1913]
Profound sympathy and sincerity. The physician needs "a profound sympathy for those who suffer" (p. xv). Practical meaning: warmth is the vehicle; argument without sympathy fails. [source: Dubois 1904/1907]
Determinism breeds indulgence. Because thoughts and acts have causes, Dubois urges tolerance rather than condemnation: "It is the action we should blame, and not the culprit" (Reason and Sentiment p. 68). Practical meaning: remove self-blame and moral contempt while still naming what should change. [source: Dubois 1911; Dubois 1904/1907 Ch. IV–VI by title only, [uncertain]]
Stoicism only for functional troubles. Dubois limits his "modest stoicism" to functional disorders and keeps medicine, drugs and physical methods for organic disease (De l'influence pp. 28, 71). Practical meaning: never persuade a patient to ignore a symptom that has not been medically assessed. [source: Dubois c. 1910]
Belief in improvability. Dubois tells readers to "believe in the possibility of improvement in the human soul" (Self-Control p. 14). Practical meaning: convey genuine optimism about change. [source: Dubois 1909]
The patient cures themself. Déjerine's ward summarised its aim as giving patients the will to cure themselves (Mazet 2017, abstract). Practical meaning: the therapist's role ends in self-education. [source: Mazet 2017; Dubois c. 1910 p. 80]
Begin with small things. Re-education "doit commencer dans les petites choses" (must begin with small things) (De l'influence p. 86). Practical meaning: start with minor ailments and daily habits before major fears. [source: Dubois c. 1910]
Live normally. "L'hygiène physique est bien simple": let oneself live, eat varied food, use alcohol with great moderation, avoid drugs as escapes (De l'influence pp. 62–64). Practical meaning: dismantle special regimes and avoidance; no symptom-driven restrictions. [source: Dubois c. 1910]
Déjerine variant: emotion before reason. "Reasoning by itself is indifferent" (p. vii); "it is feeling which creates the atmosphere of confidence" (p. viii). Practical meaning: if argument is not landing, work on trust and emotional disclosure first. [source: Déjerine & Gauckler 1913]

4. Intervention inventory

Dubois and Déjerine describe a style of conversation and a set of recurring moves rather than named techniques; the headings below are descriptive labels, not their terms, except where quoted. Steps are written for a modern psychotherapist and are [synthesis] where they go beyond what the sources state. All example language is illustrative unless in quotation marks with a citation.

4.1 Examination as a therapeutic act

Purpose / when: At intake for any bodily complaint. Dubois's honest reassurance depends on having looked: in his palpitation vignette the doctor examines thoroughly before calmly giving his opinion (De l'influence p. 54). Déjerine devotes a chapter to examining and questioning the patient (Ch. XX [uncertain]). [source: Dubois c. 1910; Déjerine & Gauckler 1913 TOC]
Steps: (1) Take a full symptom history: onset, circumstances, emotional events around onset, what the patient fears the symptom means. (2) Ask what medical assessment has been done and by whom; if inadequate, refer to a physician before treating the symptom as functional [synthesis]. (3) Ask what the patient has been told by previous doctors and what regimes (diets, rest, remedies) they follow. (4) Record which symptoms worsen with attention, anticipation or emotion and which fluctuate with distraction or pleasant company (De l'influence p. 36).
Example language (illustrative): "Before we talk about what might be keeping this going, I want to be sure the medical side is properly covered. Tell me what tests you have had, and what you were told."
Watch for: red-flag or progressive symptoms (refer; do not persuade); the patient experiencing questions about emotion as an accusation that it is "all in the head". Working: the patient feels taken seriously and the medical question is settled enough to stop dominating sessions.

4.2 The intimate friendly conversation

Purpose / when: From the first meeting; Dubois says he comes to know a patient through "an intimate friendly conversation" (p. ix). It is both assessment and the vehicle of influence. [source: Dubois 1904/1907 p. ix; Rosenfluh 2006]
Steps: (1) Sit as a dialogue partner, not an authority behind instruments (Dubois famously set aside the stethoscope and reflex hammer for the conversation; Rosenfluh 2006). (2) Let the patient tell the whole story at length, including worries they think trivial. (3) Respond with plain, warm, non-technical language; use humour where it fits (De l'influence p. 54). (4) State your genuine view of their situation as you understand it, without hedging into vagueness.
Example language (illustrative): "Let's just talk this through properly, without rushing. Tell me how a bad day goes, from the moment you wake up."
Watch for: the patient performing for an authority figure; the therapist sliding into lecturing. Working: the patient volunteers fears and private judgements they had not voiced to doctors.

4.3 Analysing the patient's mentality

Purpose / when: After the history; Dubois tells physicians to "analyze the psychology of our patient, classify the phenomena" (p. xii). He grouped the psychic stigmata of the psychoneuroses as heightened suggestibility, fatigability, sensitivity and emotional excitability, all traced to fear and timidity (Ärzteblatt; Ch. IX–XII by title). [source: Dubois 1904/1907; Ärzteblatt]
Steps: (1) For each symptom, identify the idea that accompanies it ("this means heart disease", "I cannot digest", "I will not sleep"). (2) Identify the feeling that idea colours (fear, discouragement, shame). (3) Identify the resulting action (avoiding, resting, dieting, checking, consulting). (4) Note the patient's general moral attitudes: self-reproach, intolerance of others, pessimism, egoistic self-focus. (5) Summarise the chain idea → sentiment → action for the patient (Reason and Sentiment p. 36).
Example language (illustrative): "So when the fluttering starts, the thought is 'something is wrong with my heart', the feeling is dread, and what you do is lie down and check your pulse. Is that a fair picture?"
Watch for: formulations the patient experiences as blame. Working: the patient adds links to the chain unprompted.

4.4 Explaining the mechanism of the symptoms

Purpose / when: Once you have the chain. Dubois shows the patient that their mentality plays a large part in forming and developing the illness (p. viii); Déjerine's "mental pedagogy" explains how and why the patient fell ill and how and why they can recover (p. vi). [source: Dubois 1904/1907; Déjerine & Gauckler 1913]
Steps: (1) Affirm that the sensations are real (De l'influence p. 50). (2) Explain, with everyday examples, that attention magnifies and distraction diminishes sensations: headaches that lift during a pleasant visit, Mesmer's effects produced by expectation (De l'influence pp. 36–39). (3) Link this to the patient's own observations from 4.1. (4) Explain how fear sustains the cycle and how fearing a symptom "summons" it (De l'influence p. 70). (5) State plainly and sincerely that the condition is curable, and why you think so. (6) Ask the patient to explain it back.
Example language (illustrative): "Your stomach really does hurt. What I want to show you is how much the watching and the worrying turn the volume up. You told me it was barely there at your sister's wedding. That tells us something hopeful."
Watch for: intellectual agreement without conviction; hearing "psychological" as "imaginary". Working: the patient begins to notice the attention–symptom link between sessions.

4.5 Socratic persuasion: testing the idea beneath the feeling

Purpose / when: The central method throughout Phase C. Dubois used Socratic dialogue to correct faulty value judgements (Ärzteblatt; Wikipedia); "the only means of altering the sentiment is to test it" (Reason and Sentiment p. 42). [source: Dubois 1911; Ärzteblatt; Robertson 2013]
Steps: (1) Pick one specific idea from 4.3. (2) Ask the patient to state it exactly. (3) Ask questions that test it against their experience and common sense: what happened the last times, what else would explain it, what would they tell a friend. (4) Offer your own reasoned view and the grounds for it; invite objection. (5) Let the patient draw the conclusion; restate it in their words. (6) Agree on one action that follows from the new conclusion (4.9). Robertson notes Dubois's patients were taught to monitor their own thoughts and challenge irrational ideas (citing Dubois & Gallatin 1908, p. 56 [uncertain]).
Example language (illustrative): "You've had this exact feeling, by your count, about forty times. What happened each time? ... So what does that suggest about what it means?"
Watch for: turning into a debate the therapist must win; the patient conceding to please. Working: the patient starts questioning the idea before you do.

4.6 Calm reassurance with encouraging examples and humour

Purpose / when: For acute fear in session or a frightened patient early in treatment. In Dubois's palpitation vignette the doctor gives his view calmly, backs it with encouraging examples ("qu'on ne meurt pas de cela": one doesn't die of that), and lets a joke turn fright into a smile, so the patient sleeps without medication (De l'influence p. 54). [source: Dubois c. 1910]
Steps: (1) Only after the medical question is settled (4.1). (2) Give your honest opinion in a calm, unhurried tone. (3) Support it with concrete examples of others who recovered or of the patient's own past recoveries. (4) Allow lightness once the patient is calmer. (5) Do not repeat reassurance on demand; move to 4.5 or 4.7 if the same question recurs [synthesis].
Example language (illustrative): "I've heard what you've described and what your doctor found. My honest view is that this is a frightened heart, not a damaged one."
Watch for: reassurance-seeking loops (see 5). Working: visible relief and a shift to discussing what to do.

4.7 Indifference to symptoms: "it is nothing, it will pass"

Purpose / when: For minor, medically cleared functional symptoms. Dubois: one must learn to say "ce n'est rien, cela passera!" (it's nothing, it will pass) and to turn one's gaze away, since attention enlarges the trouble (De l'influence p. 70); he restricts this "modest stoicism" to functional disorders (p. 71). [source: Dubois c. 1910]
Steps: (1) Agree which symptoms are covered (cleared, recurrent, harmless). (2) Agree a short phrase in the patient's own words. (3) When the symptom appears: notice it, use the phrase, return attention to the task at hand. (4) Stop checking, monitoring and discussing the symptom with others [synthesis]. (5) Review in session what happened to intensity and duration.
Example language (illustrative): "When the tingling starts, try: 'I know this one. It's nothing; it will pass.' Then go back to whatever you were doing."
Watch for: the phrase becoming a ritual or a suppression effort; Dubois himself notes that willpower does not stop recurring hurt, "another mental attitude" does (Self-Control pp. 36–37). Working: symptoms occupy less time and attention, even if still present.

4.8 Insomnia: stop pursuing sleep

Purpose / when: Sleep complaints; Dubois's own illustration of persuasion: "Don't look for sleep; it flies away like a pigeon when one pursues it" (p. x). Sleep disturbances have their own chapter (Ch. XXVI [uncertain]). [source: Dubois 1904/1907]
Steps: (1) Explore the beliefs that make sleeplessness frightening ("I can't function", "it will damage me"). (2) Test them (4.5) against nights already survived. (3) Explain that effort and watching for sleep keep the mind alert. (4) Agree that the patient will lie restfully without trying to sleep and without clock-watching. (5) Drop sleep rituals that express fear [synthesis].
Example language (illustrative): "Tonight, the only job is to rest. If sleep comes, fine. If not, you have rested, and you have survived nights like that before."
Watch for: persistent insomnia suggesting depression, another disorder or a medical cause (assess and refer). Working: less dread at bedtime; sleep usually follows.

4.9 Resuming normal function despite symptoms

Purpose / when: Once explanation and persuasion have taken hold. Dubois held that a persuasive physician can return a nervous dyspeptic to a normal diet (De l'influence p. 51), that moral fatigue must be shaken off when duties call (pp. 72–73), and that one must believe from the start in the possibility of enduring conditions without harm (p. 77); Déjerine warns that physicians devoted to dietetics worsened some patients (p. 7). [source: Dubois c. 1910; Déjerine & Gauckler 1913]
Steps: (1) List restrictions and avoidances the patient has adopted (food rules, rest, avoided places, drafts, flowers; De l'influence pp. 74–75). (2) Start with the smallest (p. 86). (3) Agree the step, the reason for it and what the patient predicts will happen. (4) Do it; review the prediction against what happened. (5) Proceed to larger steps. For eating, aim at ordinary, varied meals with no targets for amount or weight; if restrictive eating, weight change or compensatory behaviour is present, assess for an eating disorder and refer [synthesis].
Example language (illustrative): "You've cut out almost everything except toast and rice. Which one food would you be willing to bring back this week, knowing you might feel some discomfort and that discomfort is not damage?"
Watch for: genuine fatigue limits (Dubois says recognise them, pp. 72–73); steps so large they confirm fear. Working: widening range of activity; symptoms becoming less relevant to choices.

4.10 Reason as arbiter: pause before acting

Purpose / when: For emotional escalation, irritability and impulsive action. Dubois: reason, like an umpire, judges in the last resort (De l'influence p. 82); stop the emotion early, as one stops a vibrating glass by touching its rim (p. 83); imagine the remote consequences before acting (Self-Control p. 61). [source: Dubois c. 1910; Dubois 1909]
Steps: (1) Identify the early signs of a rising emotion. (2) Agree a pause ("finger on the glass"). (3) In the pause, name the idea behind the feeling and ask whether reason endorses it (4.5 in miniature). (4) Consider immediate and later consequences of the intended act. (5) Act on the reasoned choice; review in session.
Example language (illustrative): "When you feel it rising, put a finger on the glass: stop, and ask what you're telling yourself and whether you'd stand by it tomorrow."
Watch for: used as suppression of all feeling (Dubois wants reasoned sentiment pushed "to enthusiasm", Reason and Sentiment p. 47). Working: fewer regretted actions; earlier noticing.

4.11 Self-observation: tracing a thought to its source

Purpose / when: Phase C–D, to loosen the patient's identification with their judgements. Dubois asks readers to trace a present thought back to what set it off (an event or an older idea) and to notice how upbringing and prejudice colour judgements we take to be our own (Self-Control pp. 46, 51–53). [source: Dubois 1909]
Steps: (1) Choose a recurrent judgement ("I am weak", "people are against me"). (2) Ask when it first appeared and who held it. (3) Ask what evidence it rests on now. (4) Have the patient write down, between sessions, two or three occurrences with what triggered them [synthesis: written record is a modern addition]. (5) Review: is this my conclusion or one I absorbed?
Example language (illustrative): "Whose voice is 'you were always the delicate one'? When did you first hear it?"
Watch for: drift into extended childhood exploration (Dubois was criticised for, and himself disclaimed, depth analysis; Ärzteblatt). Working: the patient treats the judgement as a hypothesis.

4.12 Learning from lapses without self-reproach

Purpose / when: After setbacks, relapses or moral failures. Dubois's advice is "not to torment ourselves with useless reproaches, but to do better the next time" (Self-Control p. 37). [source: Dubois 1909]
Steps: (1) Describe the lapse factually. (2) Identify what would have been the better act. (3) Identify what made it hard (fear, fatigue, an old idea). (4) Agree what to do next time. (5) Explicitly drop further self-blame (link to 4.13).
Example language (illustrative): "Let's not spend energy punishing yourself for Tuesday. What would you want to do differently next time, and what will help you do it?"
Watch for: the therapist's tone becoming judgemental. Working: setbacks shorten and are discussed openly.

4.13 Determinism and indulgence: dissolving blame

Purpose / when: For harsh self-condemnation, resentment and intolerance. Dubois built a chapter of his textbook on universal determinism (Ch. IV–V by title; Robertson cites p. 47) and drew from it "true indulgence" toward self and others; "It is the action we should blame, and not the culprit" (Reason and Sentiment p. 68). Self-Control has chapters on tolerance and indulgence (by title). [source: Dubois 1911; Robertson 2013; Dubois 1904/1907 and 1909 TOC; detailed argument [uncertain]]
Steps: (1) Identify the person being condemned (self or other). (2) Explore the causes that led to the act: circumstances, upbringing, state of mind. (3) Separate judging the act (still wrong or unwise) from condemning the person. (4) Ask what follows practically: repair, boundary, forgiveness, or acceptance of what cannot be changed (Dubois's Stoic acceptance of necessity; Robertson 2013).
Example language (illustrative): "Given everything that was pressing on you that day, it makes sense that you snapped. That doesn't make it right, and it doesn't make you contemptible either."
Watch for: use to excuse ongoing harm, including abuse the patient is experiencing (do not counsel tolerance of abuse) [synthesis]. Working: less rumination about blame; more focus on what to do.

4.14 Building principles in advance: moral education

Purpose / when: Phase D, to make change durable. Dubois advises firm principles prepared beforehand, which act like cushions that deflect chance thoughts (Self-Control pp. 40–42); self-education starts in small things (De l'influence p. 86) and replaces self-focus with concern for others (p. 87). The Self-Control chapter list (meditation, moderation, patience, courage, sincerity, kindness) gives the themes. [source: Dubois 1909; Dubois c. 1910]
Steps: (1) Ask what kind of person the patient wants to be in the domains where symptoms ruled them. (2) Turn this into two or three short principles in their own words. (3) Agree small daily occasions to practise each. (4) Add one regular act of attention to others. (5) Review which principles held under pressure.
Example language (illustrative): "If you decide now how you want to meet a bad morning, you won't have to decide it at 6 a.m. when you feel awful. What would your rule be?"
Watch for: moralising (see 5). Principles must be the patient's, not the therapist's. Working: the patient cites their own principle in a difficult moment.

4.15 Philosophical reading as homework

Purpose / when: For reflective patients in Phase D. Dubois prescribed Seneca's letters to at least one patient and drew on Socrates, Epictetus, Seneca and Marcus Aurelius, calling their ideas "absolutely modern" (Robertson 2013). [source: Robertson 2013; frequency of use [uncertain]]
Steps: (1) Offer a short passage relevant to the patient's theme (e.g., Seneca on bearing illness; the idea that suffering depends partly on judgement). (2) Ask the patient to note one sentence they agree with and one they doubt. (3) Discuss in session and link to their own principles.
Example language (illustrative): "Seneca wrote a lot about getting through illness. Would you read this short letter and tell me what you'd keep from it?"
Watch for: reading used as avoidance of action; cultural or religious mismatch. Working: the patient borrows phrases to steady themselves.

4.16 Patient-drawn diagram of worry layers

Purpose / when: To make the amplification of a trouble by worry visible. Robertson reports a pencil diagram, drawn by one of Dubois's patients, showing how each layer of worry enlarges the physical or emotional trouble, linked to the maxim "He who knows how to suffer suffers less". [source: Robertson 2013; original source of the anecdote [uncertain]]
Steps: (1) Draw a small circle for the original trouble. (2) Ask the patient to add a ring for each layer of worry about it (what it means, what will happen, what others think). (3) Compare the size of the core with the whole. (4) Ask which rings could be set down.
Example language (illustrative): "Let's put the actual pain in the middle. Now draw a ring for each worry you've added to it."
Watch for: the patient feeling the core is being minimised; keep the core respected. Working: the patient spontaneously distinguishes "the pain" from "the worry about the pain".

4.17 Rest, isolation and diet (modified Weir Mitchell cure): historical only

What was done: Dubois used a modified version of Weir Mitchell's rest cure (rest in bed, isolation, a preparatory milk diet, overfeeding, massage; Ch. XIX–XXI by title), but placed the moral treatment at its centre and by his own account no longer used isolation except in serious cases (p. xiii). Clinic patients agreed in advance to a month without visitors, a darkened room and strict diets (Rosenfluh 2006). Déjerine held isolation was "not absolutely imperative" and a means of making psychotherapy possible, not a treatment in itself (pp. vi–vii; Mazet 2017). [source: Dubois 1904/1907 TOC and p. xiii; Rosenfluh 2006; Déjerine & Gauckler 1913; Mazet 2017]
Modern use: Do not reproduce. Enforced isolation, bed rest, darkened rooms and imposed feeding are restrictive, carry physical risks and conflict with current consent and autonomy standards; the paternalism of the Mitchell cure is a recognised harm (AJP 2007). What survives as usable is the rationale: a temporary break from a symptom-reinforcing environment can be arranged voluntarily (a planned few days away, reduced demands during an acute phase) with the patient's free choice [synthesis].
Watch for: any patient asking for withdrawal as treatment: assess whether it is avoidance or depression rather than recovery [synthesis].

4.18 Between-session letters

Purpose / when: Throughout and after treatment. Dubois, though overworked, wrote long letters to patients following up points raised in sessions (Rosenfluh 2006). [source: Rosenfluh 2006]
Steps (modern): (1) Agree whether written contact is part of the frame and how often. (2) After key sessions, send a brief summary: the explanation reached, the step agreed, one encouraging observation. (3) Respond to patient letters at set times, not on demand [synthesis].
Example language (illustrative): "As we said today: the dizziness is a sign of tension, not of a stroke, and this week you'll walk to the shop without your stick."
Watch for: dependence or boundary drift. Working: the patient rereads and quotes the letter.

4.19 Déjerine variant: confession and the psychotherapy of confidence

Purpose / when: When reasoning is not landing, or as the primary approach in Déjerine's version. Psychotherapy works when the patient "has confessed his entire life" (p. viii) and believes in the physician; "It is faith that saves" (p. viii). Listen, build trust, then guide back to sound reasoning (Vandereycken 1990, p. 10). [source: Déjerine & Gauckler 1913 pp. v–viii; Vandereycken 1990; Mazet 2017]
Steps: (1) Invite a full account of the patient's life and emotional history, including emotions linked to symptom onset (Déjerine traced the psychoneuroses to emotion: repeated emotion in neurasthenia, sudden emotion in hysteria; Mazet 2017). (2) Receive it without judgement. (3) Show that you understand how these emotions produced the symptoms. (4) Only then explain and re-educate (4.4–4.9). (5) Be available and consistent; Déjerine ties effectiveness to the therapist's availability (Mazet 2017).
Example language (illustrative): "I'd like to hear the whole of it, not just the symptoms: what your life has been like, and what was happening when this began."
Watch for: idealisation of the therapist and dependence (5). Working: emotional disclosure followed by greater openness to explanation.

4.20 Déjerine variant: symptom-specific re-education

Purpose / when: For particular functional symptoms (digestive, urinary, respiratory, cardiovascular, motor, sensory). Déjerine & Gauckler devote two chapters to "special therapy" of each group of functional manifestations, after a chapter on general psychotherapy and one on "adjuvants" (Ch. XXII–XXV). [source: Déjerine & Gauckler 1913 TOC; content [uncertain]]
Steps: The specific procedures could not be verified. The general pattern consistent with both authors is: explain the specific mechanism (4.4), then have the patient resume the avoided function directly and progressively (4.9) with encouragement [synthesis]. Consult Ch. XXIV–XXV before applying to a specific symptom.
Watch for: symptoms needing medical or specialist physical rehabilitation (e.g., functional neurological disorder; refer to current multidisciplinary care) [synthesis].

4.21 Family guidance: example and moral contagion

Purpose / when: When relatives' anxiety or overprotection sustains symptoms, or the patient is a parent. Dubois warns nervous parents of "moral contagion" and says the best education is by example (De l'influence pp. 67–68); in Reason and Sentiment he advises reasoning with children compassionately rather than by authority (pp. 53–59). [source: Dubois c. 1910; Dubois 1911]
Steps: (1) With consent, meet relevant family members. (2) Explain the attention–fear mechanism (4.4). (3) Ask them to stop symptom enquiries and special accommodations, and to respond to the patient's normal activity instead [synthesis]. (4) For parents: model calm handling of minor ailments; explain reasons to children rather than command.
Example language (illustrative): "The kindest thing now is to ask her about her day, not about her stomach."
Watch for: family conflict or blame of the patient. Working: fewer symptom conversations at home.

5. Handling problems

The primary sources say little about handling difficulties directly; the critiques of contemporaries (Déjerine, Freud, Janet) and later historians identify the main failure modes. Responses below are [synthesis] unless a source is given.

The argument isn't landing (stuck client). Déjerine's critique is the guide here: reasoning alone "is indifferent" without emotional confidence (p. vii). Response: stop arguing; return to listening and to the patient's full story (4.19); check whether the patient feels understood; restate the explanation using their own observations rather than yours. If still stuck after several sessions, reformulate: the idea you are targeting may not be the one driving the fear. [source: Déjerine & Gauckler 1913; response [synthesis]]
Resistance as counter-argument. Persuasion easily becomes a debate the therapist must win. Response: concede points that are true; ask the patient to state the strongest case for their fear, then test it together (4.5); never use authority in place of reasons (Dubois: authority "is decidedly not a rational means", Reason and Sentiment p. 38). If the patient yields only to your authority, treat that as a warning sign of suggestion, the very thing Dubois rejected. [source: Dubois 1911; response [synthesis]]
Feeling dismissed or blamed ("you're saying it's all in my head"). The commonest rupture in this approach. Response: repeat Dubois's own position that the suffering is real (De l'influence p. 50); acknowledge the misunderstanding explicitly; separate cause from blame (4.13); invite the patient to say what felt dismissive. [source: Dubois c. 1910; response [synthesis]]
Paternalism and moralising. Known risk of the method (Freud dismissed it as "ethical encouragement", Ärzteblatt). Response: keep moral education patient-led (principles in their words, 4.14); avoid telling the patient what is virtuous; check values fit the patient's culture and beliefs; drop Stoic or philosophical framing if it is not welcome. [source: Ärzteblatt; Rosenfluh 2006; response [synthesis]]
Overwhelm. Explanation and exposure to avoided activity can flood an anxious patient. Response: slow down; begin with smaller things (De l'influence p. 86); reduce the step size in 4.9; use 4.6 (calm, honest reassurance) once, then return to the plan. Respect genuine fatigue limits (pp. 72–73). [source: Dubois c. 1910; response [synthesis]]
Non-adherence to agreed steps. Dubois believed success was near-certain when patients understood exactly what was asked and followed it (Ärzteblatt, citing an 1886 paper). Response: check the patient understood and agreed with the reason for the step, not just the step; make it smaller; review the prediction the patient made; treat the lapse as in 4.12, without reproach. [source: Ärzteblatt; Dubois 1909 p. 37]
Reassurance-seeking loops. Repeated requests for reassurance feed the fear Dubois targets. Response: give your honest view once (4.6); thereafter, reflect the request back as a question for the patient to reason through (4.5) and agree a limit on reassurance with the patient and family (4.21). [synthesis]
Dependence on the therapist and idealisation. Dubois has been described as a charismatic healer and benevolent father figure, possibly unaware of transference (Rosenfluh 2006); Déjerine explicitly relies on the patient's faith in the physician. Response: name the relationship openly; shift credit for gains to the patient; space sessions as progress is made; aim for self-education (4.14). [source: Rosenfluh 2006; Déjerine & Gauckler 1913; response [synthesis]]
Missed organic disease. The central danger in persuading patients that bodily symptoms are functional. Dubois limited his stoicism to functional troubles and expected physicians to keep judging organic disease (De l'influence pp. 28, 71). Response: medical clearance before 4.7 or 4.9; re-refer if symptoms change in character, new signs appear or the pattern does not fit. [source: Dubois c. 1910; response [synthesis]]
Severe depression, suicidality or psychosis. Dubois grouped melancholia with the psychoneuroses and wrote a chapter on the limits of psychotherapy (Ch. VIII, XV by title [uncertain]). Persuasion alone is not an adequate response to severe mood disorder, psychosis or suicide risk. Response: conduct a standard risk assessment (ideation, intent, plans, history, protective factors); develop a collaborative safety plan; where relevant, discuss lethal-means safety (safe storage or removal of means, involving family with consent); refer for psychiatric assessment and evidence-based treatment; do not use "it is nothing" framing for mood or suicidal symptoms. [synthesis]
Selection bias: the unmotivated patient. Dubois's clinic selected motivated patients through its admission conditions, a criticism historians consider justified (Rosenfluh 2006). Response: assess motivation early; if low, work first on the patient's own reasons for change; consider whether another approach suits better. [source: Rosenfluh 2006; response [synthesis]]
Lack of understanding of how the suffering is structured. Janet criticised Dubois for curing without seeking to understand the structure of the patient's suffering (Ärzteblatt). Response: if symptoms persist or shift, deepen the formulation (4.3, 4.11) rather than intensifying persuasion; consider referral to a modern approach with a fuller model (see below). [source: Ärzteblatt; response [synthesis]]
When to switch. Persuasion therapy is a historical precursor with no outcome evidence base by current standards. For anxiety, health anxiety, insomnia and persistent physical symptoms, its core moves (explanation, testing beliefs, dropping safety behaviours, Stoic acceptance) are developed and tested in cognitive therapy, REBT, CBT for insomnia, CBT for health anxiety and CBT-based treatment for functional disorders; use these when the condition warrants a current evidence-based protocol.
