Interpersonal group therapy (Yalom)

1. Introduction

Version followed: Yalom & Leszcz, The Theory and Practice of Group Psychotherapy, 6th ed. (Basic Books, 2020), the interpersonal outpatient process group; for wards, Yalom's agenda-group model from Inpatient Group Psychotherapy (1983). The book itself is not drawn on; publisher, yalom.com and library catalogue pages give descriptions and the 5th-ed. table of contents only. Verified in this revision: the chapter structure (5th-ed. table of contents), the new 6th-ed. chapter on online groups, and the preparation, format, size and misconception points that the updated AGPA Practice Guidelines attribute to Yalom & Leszcz (2020); and the eleven primary therapeutic factors of the 6th ed. (yalom.com; Chelios & Vlachos 2026), with the 13-row AGPA table explained as a finer research breakdown. A student flashcard summary used in the first draft has been dropped as a source; claims that rested on it alone are now tagged [unconfirmed] (not confirmed in the book or any legitimate source; treat as unverified). Still unverified: the stage sequence, Yalom's named norms, his problem-member advice, termination procedures, the online chapter's content, inpatient timings and the lower-level inpatient model.

Interpersonal group therapy is a long-term or time-limited process group, typically 7–8 members meeting weekly. The group works as a social microcosm: the interpersonal patterns that cause members distress outside the group sooner or later show up between members in the room. Change comes from two steps. First, members experience each other in the here-and-now. Second, the group illuminates that process, through feedback and process commentary, so each member sees their behaviour, its impact and the beliefs driving it. Insight is then joined to a corrective relational experience that disconfirms the member's pathogenic belief, and new behaviour is practised in the group before being carried outside. Leszcz describes clients as drawn to "seek what is familiar, not necessarily what nourishes our growth"; the group exposes and interrupts that pattern. [source: Leszcz interview; yalom.com reading guide; AGPA citing Yalom & Leszcz 2020 for linking symptoms to interpersonal patterns and self-other schemas, with the group as a "laboratory"]

Therapeutic factors: Yalom & Leszcz (6th ed., 2020) describe eleven primary therapeutic factors: instillation of hope, universality, imparting information, altruism, corrective recapitulation of the primary family group, development of socializing techniques, imitative behaviour, interpersonal learning, group cohesiveness, catharsis and existential factors. [source: yalom.com reading guide (6th ed.); Chelios & Vlachos 2026, citing Yalom & Leszcz 2020] Longer lists circulate because research uses finer categories: the AGPA guidelines' Table 1, captioned "Therapeutic Factors (Yalom and Leszcz, 2020)", has 13 rows, splitting interpersonal learning into input and output and adding self-understanding [source: AGPA guidelines]; studies with Yalom's 60-item questionnaire score 12 factors, including self-understanding, family re-enactment and identification [source: Vlastelica et al. 2001]. This guide uses the eleven. In this model interpersonal learning and cohesion are the engine; the other factors operate alongside. [source: AGPA guidelines; yalom.com]

2. Framework

The model is not manualised into fixed sessions. Its structure is a sequence of therapist tasks across the life of the group. [source: Yalom & Leszcz 5th ed. table of contents; Leszcz interview]

Phase A: Planning and composition (before recruitment).

Goal: define the group's type, goals and way of working; check that the setting needs the group and can support it; brief referral sources. [source: AGPA]
Format (AGPA citing Yalom & Leszcz 2020): about 90 minutes, never more than two hours; weekly; 7–8 members is optimal and 4 or fewer turns passive and individual-like; closed time-limited groups should start with 9–10 to absorb dropout; private, consistent room and time. AGPA, citing Yalom & Leszcz, notes that the first 60 minutes are when main themes emerge, and links weekly meetings to "greater therapeutic connection" (p. 346).
Composition: process groups are usually heterogeneous in problem area. Plan composition before selecting individuals, aiming for enough similarity for cohesion and enough difference for useful friction. [source: AGPA]

Phase B: Selection and pregroup preparation (1 or more individual meetings with the group leader).

Goal: a working alliance on goals, tasks and relationship. Leszcz calls the alliance "the best predictor of outcomes". Confirm fit; give a rationale; predict how the client's difficulties will show up in the group; reduce anxiety; agree group norms. The therapist decides whether a candidate fits; the candidate decides whether to join, and keeps the right to withdraw or adjust participation (AGPA citing Leszcz 2004). Explain here-and-now work and check the candidate's investment in it (AGPA citing Yalom & Leszcz 2020). [source: Leszcz interview; AGPA]
The leader does this, not an intake worker. Leszcz calls delegating it "penny-wise and pound-foolish".
Move on when the client understands the here-and-now task, accepts the agreements (confidentiality, attendance, outside contact, how leaving is handled), and has at least one interpersonal goal that could become visible in the group. [synthesis, built on AGPA content]

Phase C: Early sessions (formative stage).

Goal: build cohesion and norms. The therapist does most of the activation: steering talk into the here-and-now from the first minute of every session, reducing threat by first highlighting positive interactions between members, and modelling feedback. [unconfirmed]
The formative stages are covered in the chapter "In the beginning" (ch. 11 in the 5th-ed. table of contents); its text is not drawn on here, and the chapters of the updated AGPA guidelines do not cover group development. Treat any named stage sequence as unverified. [uncertain] In practice [synthesis]: expect early orientation and dependency on the leader, then a period of conflict or challenge to the leader, then deeper cohesion. Treat conflict as a developmental task, not a failure.

Phase D: Working (advanced) group.

Goal: members carry the therapist's tasks themselves. Leszcz says mature groups ask process questions on their own; a secondary summary (unconfirmed) says activation starts as the therapist's job and later passes to the group. Most interpersonal learning happens here, through repeated cycles of enactment, feedback, illumination and new behaviour. [source: Leszcz interview; hand-over of activation unconfirmed]
Criterion for being in this phase [synthesis]: members spontaneously comment on each other's in-room behaviour, link it to their own goals, and the leader mainly comments on group-level process.

Phase E: Termination. Individual members leave an open group when their goals are met; closed groups end on a set date. The 5th edition places this in ch. 12, "The advanced group" (catalogue table of contents); its text is not drawn on here. AGPA's agreements list (citing Rutan et al. 2020a) includes how termination or leaving is managed. [uncertain] Practice [synthesis]: ask the member to announce leaving several sessions ahead; review their goals and changes with the group; let members give final feedback; process the group's reactions to the loss.

Session length and count. Outpatient interpersonal groups are commonly open-ended and long-term. A minimum stay or contract length is not specified. [uncertain]

Inpatient variant (agenda group). 3–5 sessions a week, 60–75 minutes, about 6 members [unconfirmed]. Each session is treated as possibly the only one a patient attends. Sequence: orientation and preparation (3–5 min: purpose, ground rules, sequence) → personal agenda go-round (20–35 min) → agenda filling (20–25 min) → summary/review (about 10 min). A demonstration video lists the segments as Orientation, Agenda Formation and Agenda Filling. Yalom's 1983 book also describes a separate model for more regressed or psychotic patients; it is not drawn on here.

3. Guiding principles

Social microcosm. Wait for the problem behaviour to appear in the room, then work with it. Leszcz: change is likelier once there is concrete in-group evidence. Practical meaning: don't rush to discuss outside problems; watch for their in-group version. [source: Leszcz interview]
Here-and-now primacy, two tiers. Activation plus illumination. Practical meaning: experience without reflection fades; reflection without experience is flat. Always do both. [unconfirmed]
Process over content. Process means how and why things are said and what passes between people, including tone, nonverbal behaviour and what is not said. Practical meaning: listen to the story, but intervene on what the telling is doing between members now. [source: Bradley deck (secondary); unconfirmed in Yalom]
"Part of the solution or part of the problem." Leszcz's working stance for judging every moment. Practical meaning: ask whether what is happening is moving members toward or away from interpersonal learning. [source: Leszcz interview]
Corrective emotional experience plus insight. Once a pathogenic belief is illuminated, the group should respond in a way that disconfirms it, then process what happened. Practical meaning: name the feared consequence and let the member see it not happen. [source: Leszcz interview]
Feedback is the core currency. Make it specific, low-inference, here-and-now and about observable behaviour, so the recipient can use it. Practical meaning: "When you did X just now, I felt Y", not character judgements. [source: Leszcz interview; feedback criteria unconfirmed]
Cohesion first. Cohesion has the strongest empirical support and is the precondition for risk-taking. Practical meaning: early on, build belonging before challenge. [source: AGPA; Leszcz interview]
Reduce threat, then deepen. Early activation highlights positive interactions. Practical meaning: the first here-and-now statements you invite should be low-risk and appreciative. [unconfirmed]
Alliance at three levels. Member–therapist, member–group, member–member. Practical meaning: track and repair all three, not only your own bond. [source: AGPA]
Therapist as culture builder. Members learn norms by watching the leader. Practical meaning: model feedback, here-and-now disclosure and non-defensive responses to criticism yourself. [unconfirmed]
Appropriate transparency. Neutrality is impossible: Leszcz says one cannot share a room "and not to disclose". Disclose mindfully, mainly here-and-now reactions that serve the group. Practical meaning: share your in-room reactions as data; keep personal history mostly private. [source: Leszcz interview]
Therapist's reactions are data. Separate objective countertransference (the impact this member has on most people) from subjective countertransference (your own idiosyncratic pull). Practical meaning: before voicing a reaction, check whether others share it. [unconfirmed]
Balanced leader activity. Too little and the group flounders; too much and it becomes dependent. Practical meaning: step back once members can do a task you have been doing. [source: Leszcz recalling Yalom's advice that a group was too dependent on him]
No taking turns. Turn-taking is a content fix for a process problem and forces premature disclosure. Practical meaning: explore why the group wants structure instead of imposing a rota (outpatient groups; the inpatient agenda go-round is a deliberate exception). [unconfirmed]
Group-level issues take priority. Group flight from an anxiety-laden topic, or an antitherapeutic norm, blocks all individual work. Practical meaning: address the group-level block first. [unconfirmed]
Your anxiety as signal. If you are too anxious to name something, the group probably is too. Practical meaning: use your hesitation to judge timing, and get supervision. [unconfirmed]
Responsibility and will. Insight must lead to action; exhorting someone to change does not work; remove obstacles and strengthen motivation instead. [unconfirmed]
No advice-giving, no mere sympathy. These pull the group away from process. Practical meaning: redirect from advice to members' reactions. [source: Leszcz interview]
Thorough preparation by the leader. Leszcz: "well-prepared clients do much better in group therapy". [source: Leszcz interview]
Calibrated entry bar. Exclusion criteria are guidelines, not rules. A wrongly admitted uncommitted member does more harm than a wrongly excluded one. No dropouts at all suggests the bar is too high. [source: AGPA; Leszcz interview]
Cultural humility. The group is a microcosm of power and privilege as well. Practical meaning: name identity and power dynamics explicitly, and know your own. [source: AGPA]
Disciplined experimentation (specialized settings). Assess the setting's fixed constraints, set achievable goals, change technique to fit, and evaluate. Practical meaning: adapt structure, not the here-and-now core. [unconfirmed]
Structure in brief, acute groups. Too much or too little structure both stall growth; inpatient groups need explicit, visible structure. [unconfirmed]

4. Intervention inventory

The items below are the procedures described in the sources. Steps are written in my own words. Example language is illustrative unless quoted and cited. Chapters on challenging members, specialized formats and procedural aids (e.g. co-therapy routines, written session summaries), the advanced group, and online groups exist in the 6th edition but are not drawn on here. Nothing from them is presented as Yalom's method. [source: 5th-ed. table of contents (Simmons and Waubonsee catalogues); Hachette pages]

4.1 Planning and composing the group

Purpose: set a frame that lets a social microcosm form and cohere. [source: AGPA]
Steps: (1) Write a one-paragraph statement of group type (interpersonal process), goals and work style. (2) Check need and feasibility in the setting: referral flow, room, time slot, fees. (3) Fix the frame: about 90 min weekly, consistent room and time; aim for 7–8 members, or 9–10 at the start of a closed group. (4) Decide composition before choosing individuals: which client variable is most critical to this group's development, and why (AGPA citing Joyce & Marmarosh 2023). (5) Prepare written material for referrers and clients: inclusion and exclusion criteria, structure, fees, goals, process, logistics. (6) Build referral links, e.g. send referrers a note after each consultation (Leszcz). [source: AGPA; Leszcz interview]
Example language (illustrative, to referrers): "This is a weekly 90-minute group for adults whose difficulties show up in relationships: feeling unseen, conflict, withdrawal. The work is learning from how members relate to each other in the room."
Watch for: over-recruiting a group around one shared symptom, which turns it homogeneous and support-focused; too few members. It is working when there is a steady referral flow and a mix of interpersonal styles. [synthesis]

4.2 Selection interview

Purpose: assess fit both ways (person to group, group to person) and form the alliance. [source: AGPA; Leszcz]
Steps: (1) Leader meets the client individually. (2) Explore goals, interpersonal history and current patterns, and the client's identity and how it may meet the group's. (3) Check agreement on goals, tasks and the nature of the relationship (Leszcz). (4) Check practical capacity: can attend reliably, sit in a group, speak, use feedback. (5) Screen for exclusions first, then assess more fully (two-step, AGPA citing Joyce & Marmarosh 2023). AGPA lists as cautions: active substance misuse, acute psychosis, need for crisis care; low motivation, hostility, marked denial, self-destructive behaviour, inability to keep norms; prejudice toward marginalised members; doubt about group. Strong motivation can offset these. (6) Optional measures: the GTQ-S (25 items, five domains, free from Routledge) and the GRQ (19 items, readiness screen, from OQ Measures). Use them as published; do not adapt items. (7) If you decline someone, explain why in therapeutic terms and recommend an alternative. [source: AGPA; Leszcz]
Example language (illustrative): "What tends to go wrong for you with people? If that happened between you and someone in this group, what might it look like?"
Watch for: a client who wants only symptom relief or advice; a goal that cannot be seen in-group. It is working when the client can name an in-group version of their problem. [synthesis]

4.3 Pregroup preparation

Purpose: reduce dropout, set expectations and seed here-and-now work. Leszcz says prepared clients stay longer, work better and drop out less. [source: Leszcz; AGPA]
Steps: (1) Explain how the group helps: distress is linked to interpersonal patterns, the group recreates them, and members learn by examining them as they happen. (2) Build a shared formulation: how this client's self-view and pattern (e.g. passivity, anger, self-effacement) is likely to show in the group, framed as an opportunity. (3) Describe the here-and-now task and corrective experience in plain terms. (4) Correct misconceptions (AGPA citing Rutan et al. 2020 and Yalom & Leszcz 2020): group is inferior to individual therapy; individuality will be lost to emotional contagion; other members will reject the client; the therapist's attention will be too scarce. Counter the last with the point that growth is possible in every moment, including when the focus is on someone else. (5) Normalise that ruptures will happen and say how they are repaired; ask what helps the client feel safe if one occurs. (6) Agree norms (see 4.4). (7) Give a written preparation handout in your own words. The book contains a personalisable preparation document (Leszcz); in the 5th edition it is the closing section "Information and guidelines for participation in group therapy" (catalogue table of contents). Not reproduced here. (8) Use as many sessions as needed: from a single 30-minute meeting to several sessions, or introductions at each session (AGPA citing Yalom & Leszcz 2020 and others), individual or small group, written, verbal, audiovisual or role-play. [source: Leszcz; AGPA]
Example language (illustrative): "You've told me people end up leaning on you and never ask how you are. Odds are that will happen here too. When it does, that's not a problem with the group; it's the moment we can actually work on it."
Watch for: the client agreeing politely without understanding. Ask them to restate the task. [synthesis]

4.4 Group agreements (norm contract)

Purpose: a safe, predictable frame. [source: AGPA citing Rutan et al. 2020]
Steps: cover (1) confidentiality, as each member's responsibility, acknowledging it cannot be enforced among members; (2) contact outside the group and dual relationships, with the expectation that outside contact is brought back into the group; (3) commitment to goals and attendance; (4) member and therapist roles; (5) boundaries and how violations are handled; (6) how to leave, e.g. discussing it in group before stopping; (7) fees; (8) time boundaries; (9) accessibility for in-person, online or hybrid groups. Review in the individual meeting and again in the first session. [source: AGPA]
Example language (illustrative): "If two of you meet outside, that's not forbidden, but it becomes part of the group's business, so we'd want to hear about it here."
Watch for: agreements kept only on paper. Refer back to them when they are tested. [synthesis]

4.5 Activation: steering into the here-and-now

Purpose: turn talk about outside or past events into live interaction between members. Leszcz calls it the most important and most challenging leader skill. [source: Leszcz; remainder unconfirmed]
Steps: (1) Start from the first minute; think here-and-now yourself. (2) When a member tells an outside story, ask how it relates to the group's task and how it could come alive in the room (questions given in a secondary training deck). (3) Shift outside → inside, abstract → specific, generic → personal, personal → interpersonal (Bradley deck; secondary, not attributed there to Yalom [uncertain]). (4) Interrupt then-and-there content when needed, and say openly that you are interrupting and why. (5) Early on, lower the threat by inviting positive, low-risk observations between members. (6) Use process questions (4.6). [source: Bradley deck (secondary); unconfirmed in Yalom]
Example language (illustrative): "You've told us your boss dismisses you. Has anyone here ever felt dismissed by you, or you by someone here today?" / "Who in the room do you feel most at ease with so far?"
Watch for: members feeling exposed too early. Start with positive feedback. It is working when members begin addressing each other by name and referring to earlier sessions. [synthesis]

4.6 Process questions

Purpose: invite members to examine their experience of the group and each other. [source: Leszcz]
Steps: (1) Notice who dominates, who is quiet, who is drawn to whom, who is avoided or feared. (2) Ask about the member's experience of the group, their expectations of others, and how they felt after past sessions. (3) Ask how others react to the pattern. (4) Ask a member to compare sessions where they behaved differently. (5) Ask questions before you have the answers; do not wait for certainty. [source: Leszcz; remainder unconfirmed]
Example language (adapted from Leszcz's case, wording illustrative): to the member who always supports others: "What's it like to give so much here and ask for so little?" To the group: "How do you feel when she does that?" Then: "How did you feel after the week you did ask for time?"
Watch for: questions that read as accusations. It is working when, over time, members ask these questions of each other without prompting. [source: Leszcz]

4.7 Process commentary and illumination

Purpose: make the meaning of what just happened understood. This is the leader's main task beyond activation. [unconfirmed]
Steps: (1) Ask yourself why this is happening, in this way, at this time. (2) Gather data: content, tone, nonverbal behaviour, who is absent, what is not said, your own reactions. (3) Track patterns across sessions (the therapist as group historian). (4) Offer the observation tentatively, supportively and without blame; avoid "always" and "never". (5) Prioritise charged moments, where learning is richest. (6) Judge the comment by whether it helps someone change, not whether it is clever. (7) Explain your interventions and their purpose when that demystifies them. [unconfirmed]
Example language (illustrative): "I notice that each time Sam raises something painful, someone changes the subject within a minute or so. I wonder what makes his pain hard to stay with here."
Watch for: intellectualised commentary with no feeling (the illumination-only error), or a rigid, aloof leader style. It is working when members take up the comment and respond with feeling. [unconfirmed]

4.8 Eliciting and shaping feedback

Purpose: interpersonal learning-input: members learn their impact on others. [source: Leszcz; AGPA]
Steps: (1) Redirect advice or sympathy toward members' lived reactions to the person in the room. (2) Ask for feedback based on in-group behaviour. In Leszcz's example, women in a group were asked how it would be to be married to a man who complained about his wife, judging from how he was in the group. (3) Coach feedback to be specific, low-inference, here-and-now and about behaviour. (4) Model it yourself. (5) Check how the recipient received it, and whether others share it (consensual validation). [source: Leszcz; remainder unconfirmed]
Example language (illustrative): "Rather than advise him, could you tell him what it's like sitting with him right now?" / "Is that reaction just yours, or do others notice it too?"
Watch for: pile-ons and scapegoating; feedback driven by a bid for dominance. Balance critical with positive feedback. [source: AGPA (scapegoating); dominance point unconfirmed]

4.9 The change sequence (from recognition to action)

Purpose: walk a member from feedback to durable change. [unconfirmed: sequence from a discarded secondary summary; wording mine]
Steps: help the member (1) recognise their behaviour with others; (2) appreciate its impact on others and on themselves; (3) decide whether they are satisfied with it; (4) find the will to change; (5) turn intent into decision and decision into in-group action; (6) consolidate and carry it outside. (7) Along the way, address the beliefs a secondary summary lists (unconfirmed): only the member can change the world they have built; change is not inherently dangerous; getting what they want requires change; they are capable of it. [unconfirmed]
Example language (illustrative): "You've heard three people say they feel kept at arm's length. Is that how you want to be with people here?" / "What would be one small way to try it differently before we finish today?"
Watch for: stalling at insight. Ask for one concrete in-group experiment. [synthesis]

4.10 Therapist transparency and here-and-now self-disclosure

Purpose: model openness, humanise the leader, and supply feedback only the leader can give. [source: Leszcz; remainder unconfirmed]
Steps: (1) Accept that you disclose anyway; choose deliberately. (2) Prefer here-and-now reactions to personal history. (3) Before voicing a reaction, sort objective from subjective countertransference: would most people react to this member this way? (4) Give the reaction as information about impact, owned as yours. (5) Do not avoid giving feedback out of boundary fears. Leszcz counts that avoidance among common errors. (6) When criticised, respond non-defensively and own your part. [source: Leszcz; AGPA (non-defensive repair); countertransference distinction unconfirmed]
Example language (illustrative): "I'll be honest: as you went into detail I found myself drifting, and I don't think it's because what you're saying doesn't matter. I wonder if others felt that too."
Watch for: disclosure that meets your needs or moves the focus onto you. It is working when members disclose more about in-room reactions after you model it. [synthesis]

4.11 Facilitating corrective emotional experience

Purpose: disconfirm a pathogenic belief through a lived experience in the group, then consolidate it. [source: Leszcz]
Steps: (1) Identify the belief and the feared consequence (e.g. "if I protest, I'll be silenced or pushed out"). (2) When the member takes the risk, help the group receive it rather than punish or smooth it over. Leszcz's case: a man's protest was welcomed so the group would not "silence him or marginalize his experience". (3) Follow with process questions: Who did you expect to support or challenge you? How do you feel about how you said it? (4) Name the contrast between feared and actual outcome. [source: Leszcz]
Example language (illustrative): "You expected that disagreeing would cost you your place here. What actually happened?"
Watch for: the group retaliating and confirming the belief; step in to protect the member and process it. It is working when the member reports feeling better known and closer. [source: Leszcz]

4.12 Using the past in the service of the here-and-now

Purpose: explain the origin of a current pattern so it makes sense and is easier to change. [unconfirmed]
Steps: (1) Start from the in-group behaviour. (2) Bring in history only to make it intelligible (e.g. Leszcz's member raised to be "seen and not heard"). (3) Focus on how the past is perceived now and how it shapes current functioning, not on digging for exact memories. (4) Return to the room. [source: Leszcz; remainder unconfirmed]
Example language (illustrative): "It makes sense that keeping quiet kept you safe growing up. Is it still keeping you safe here, or keeping you invisible?"
Watch for: the group drifting into extended history-telling. Bridge back. [synthesis]

4.13 Group-as-a-whole commentary

Purpose: remove group-level blocks that stall every member. [unconfirmed]
Steps: (1) Notice group flight from an anxiety-laden topic (e.g. a member leaving, the leader's absence, conflict) and antitherapeutic norms (e.g. politeness only, advice-giving). (2) Comment on the group, not on an individual. (3) A secondary summary also lists Bion-derived basic assumptions (dependency, fight/flight, pairing) as a lens for whole-group process; use them to understand the group, not as jargon in the room. (4) Give group-level issues priority over individual ones. [unconfirmed]
Example language (illustrative): "We've talked about everything except Maria's empty chair. I wonder what it's like for us to sit with her leaving."
Watch for: blaming one member for a group-wide avoidance. [synthesis]

4.14 Mobilising will and in-group experiments

Purpose: move from insight to action. [unconfirmed]
Steps: (1) Don't exhort. (2) Identify the obstacle: usually the belief that change is dangerous. (3) Invite an "as if" experiment: act for a few minutes as if the feared behaviour were safe. More rarely, enact the feared behaviour directly in the group. (4) Process the outcome. (5) Recognise resistance as pain avoidance that sets the member's pace; noticing it is the first opening for change. [unconfirmed]
Example language (illustrative): "For the next ten minutes, would you be willing to act as if asking for something here were allowed, and see what happens?"
Watch for: experiments imposed rather than chosen. Get consent and let the member set the size. [synthesis]

4.15 Culture building and helping members accept commentary

Purpose: make feedback and self-examination group norms. [source: Leszcz; remainder unconfirmed]
Steps: (1) Model feedback and here-and-now disclosure. (2) Explain the purpose of what you do. (3) Expect resistance to process commentary, which a secondary summary (unconfirmed) attributes to social taboos, fear of retaliation and its disruption of power hierarchies; name these anxieties gently. (4) Handle tense material in a balanced, non-blaming, self-revealing way. (5) Don't remove obstacles too fast; working through them is the work. (6) Remind members of the primary task when they seek the most powerful person's approval instead. [unconfirmed] The 6th edition's chapter on basic tasks, including Yalom's named norms, is not drawn on here. [uncertain]
Example language (illustrative): "Commenting on each other's behaviour breaks ordinary social rules, and that can feel risky. Here it's how we help each other."

4.16 Working with identity, power and ruptures

Purpose: keep the group safe and inclusive; repair alliance breaks. [source: AGPA]
Steps: (1) Examine your own identities, biases and privileges before the group starts. (2) Invite members, in preparation and in group, to name social locations and how these may meet the group and the leader. (3) Name power, privilege and oppression as they appear in the room. (4) When a rupture happens (including microaggressions or invalidation), attend to it promptly, without defensiveness or interpretation: acknowledge, take responsibility for your part, invite the hurt member's experience, and involve the group. (5) Address scapegoating, avoidance of the task and boundary violations. [source: AGPA]
Example language (illustrative): "I think what I said a moment ago landed as dismissive of your experience as a Black woman in this group. I'd like to hear how it landed, and I want to own it."
Watch for: pressure on the hurt member to educate the group. Share that load. [synthesis]

4.17 Co-leadership

Purpose: share the emotional load and support training. [source: Leszcz; AGPA]
Steps: (1) Before starting, agree goals, theoretical approach, roles and logistics; discuss identity differences and how insensitivity will be handled. (2) Meet before and after every session. (3) Expect rivalry and tension; work them through in good faith. (4) Don't let one leader stay passive; Leszcz notes this models disengagement. [source: Leszcz; AGPA]
Watch for: members splitting the leaders or playing one against the other. Process this in the post-session debrief. [synthesis]

4.18 Inpatient agenda group (acute wards)

Purpose: give a possibly one-off session value. Goals per a secondary summary (unconfirmed): engage patients, show that talking helps, help each identify an issue, reduce isolation, let patients help each other, ease hospital-related anxiety, and spark engagement that continues after discharge. [source: psychotherapy.net (segments); goals unconfirmed]
Steps: (1) Orientation (3–5 min): state the purpose, ground rules and the session sequence; start on time; door closed; call it "their" group. (2) Agenda go-round (20–35 min): each patient forms a personal agenda that (a) expresses a wish to change, (b) is interpersonal, and (c) can be worked on in this room today. Help shape vague or hospital-reason agendas into this form. A secondary summary (unconfirmed) notes that where anger is involved, the leader steers toward mild current irritation ("young anger") rather than old grievances between members. (3) Agenda filling (20–25 min): work as many agendas as possible, linking members with similar agendas and inviting feedback. (4) Summary (about 10 min): review the session with a here-and-now self-reflective loop; where observers are present, make the observation visible. [source: psychotherapy.net video page (segment names); timings and details unconfirmed] Yalom's original observer-review procedure and his lower-level (regressed/psychotic) model are not drawn on here. [uncertain]
Therapist tasks: give direct support (empathy, acceptance) and indirect support via cohesion; reinforce adaptive acts at once; keep the structure explicit. With a frightened patient who wants to leave: say you hope they stay, acknowledge the fear, and offer to let them observe; they cannot be made to stay. With a disruptive psychotic patient: own your discomfort and set firm limits to protect the group. [unconfirmed]
Example language (illustrative): "In the next few minutes, each of us will pick one thing about how you get along with people that you'd like to change, something we could work on right here today." / Shaping: "You'd like to feel less alone. Is there someone here you'd be willing to get to know a bit better today?"
Watch for: agendas drifting to diagnosis or discharge; structure too loose (chaos) or too tight (no autonomy). [unconfirmed]

4.19 Measurement-based care

Purpose: inform selection and track progress. The 6th edition adds a section on measurement-based care; its content is not drawn on here. [source: Hachette page; AGPA]
Steps: use published readiness and selection measures (GTQ-S, GRQ) and routine symptom measures as their publishers specify. Review scores with members individually. [source: AGPA; administration routine is synthesis]

4.20 Online groups

The 6th edition adds a new chapter on online groups, written in response to the COVID-19 pandemic (Hachette library page). Its text is not drawn on here. [uncertain] AGPA's agreements guidance covers online and hybrid accessibility: captioning, translation, flexible camera use. [source: AGPA; Hachette page]

4.21 Termination work [synthesis]

Purpose: consolidate gains and model a good ending.
Steps: (1) The member announces leaving in group, ideally several sessions ahead (an AGPA agreements item). (2) Review goals, changes and remaining work. (3) Invite final feedback both ways. (4) Process the group's reactions: loss, envy, abandonment. (5) For closed groups, mark the countdown and revisit the group's history. Specific Yalom & Leszcz termination procedures are not drawn on here. [uncertain]

5. Handling problems

The book's chapter on problem members (5th ed. ch. 13, "Problem group members", per catalogue table of contents; 6th-ed. title not confirmed) is not drawn on here. The label "help-rejecting complainer" predates the current edition (e.g. Berger & Rosenbaum 1967, International Journal of Group Psychotherapy; citation page only). A secondary training deck names the monopolist, the silent or withdrawn member and the help-rejecting complainer, but gives no interventions. Guidance for those types below is therefore my own [synthesis], built on the model's principles and not attributed to Yalom.

Group slides into advice and sympathy (e.g. a member shares despair and others tell him how to fix his life). Name the pull warmly, then redirect to reactions in the room: "(illustrative) We're working hard to fix this for him. What is it like to sit with him while he feels this?" [source: Leszcz; Bradley deck scenario; wording synthesis]
Stuck or low-energy group. Check for group flight from an unspoken topic (an absence, a dropout, the leader, conflict) and comment at group level (4.13). Check your own activity: too much breeds dependence, too little lets the group flounder. Ask about the group's experience of the last few sessions. [source: process questions per Leszcz; rest synthesis]
Resistance to here-and-now work ("this is artificial", "I came to talk about my marriage"). Treat it as pain avoidance that sets the member's pace. Acknowledge that the taboo on commenting on each other is real, and link the outside problem to its in-room version. Don't force it; return to it. [source: linking per Leszcz; rest synthesis]
A member protests the group's approach or optimism. Leszcz used process questions: who the member expected would support or challenge him, and how he felt about the way he voiced his disagreement. The protest becomes the work. [source: Leszcz]
Overwhelm or flooding. In outpatient groups, slow down; shift from confrontation to support; ask the group what the member needs right now; return to the material later. On inpatient wards, increase visible structure, keep anger to mild current irritation, and offer the option to observe. [synthesis; inpatient points unconfirmed]
Pile-on or scapegoating. Interrupt. Ask what the target carries for the group and what each member's own share is. Protect the member, then process at group level. [source: AGPA names scapegoating; steps synthesis]
Rupture with the leader (including microaggressions). Respond promptly and non-defensively, without interpreting. Acknowledge impact, own your part, invite the group's experience. Rebuilding trust prevents early termination. [source: AGPA]
Monopolising member [synthesis]. Don't simply silence them. Ask the group what it is doing by letting one person carry the session (group collusion), then invite feedback to the monopoliser on their impact, framed with care, and explore what talking protects them from.
Silent member [synthesis]. Make low-pressure invitations ("(illustrative) Where are you with this?"), notice nonverbal engagement, ask what would make speaking easier, and explore how others interpret the silence. Don't use go-rounds to force disclosure (see the no-turn-taking principle, itself unconfirmed).
Help-rejecting complainer [synthesis]. Stop the advice–rejection cycle. Ask members how they feel when their help is turned down, and explore what the member wants from the group other than solutions.
Absence, lateness and non-attendance [synthesis, using AGPA agreements]. Treat absences as group events: ask how the group feels about the empty chair; contact the absent member between sessions to invite them back; review the attendance agreement with them individually if it recurs.
Dropout. Expect it; reported rates are roughly 10–40%. A group with no dropouts may have too high an entry bar; a high rate suggests screening or preparation gaps. Reduce it with thorough preparation done by the leader, and with closed groups over-recruited to 9–10. Process each dropout with the remaining members. [source: Leszcz; AGPA]
Selection mismatch (a member who cannot use the group, or harms it). Plan a reparative response: individual meeting, a different format, or a referral, explained therapeutically, and help the group process the loss. [source: AGPA; steps synthesis]
Outside contact, subgroups or romance between members [synthesis, using the AGPA agreement that outside contact is brought into the group]. Invite disclosure in group, explore what the pairing or subgroup does for and to the group, and remind members of the agreement. Secret subgroups block work until they are named.
Confidentiality breach [synthesis]. Bring it to the group, restate the agreement, and let members voice reactions. Consider whether the breaching member can remain.
Co-leader tension. Expect it; process it between sessions in good faith. Don't let a co-leader stay passive. [source: Leszcz]
Frightened inpatient wanting to leave. Say you hope they stay, acknowledge the fear, and allow observation; never physically prevent leaving. Disruptive psychotic inpatient: own your discomfort and set firm limits to protect the group. [unconfirmed]
Suicidal disclosure in group [synthesis]. Acknowledge it in the room without turning the session into a risk interview. Assess risk with the member individually after the session, using your service's standard protocol (risk and protective factors, safety planning, lethal-means counselling on storage and removal). Process the group's reactions next session. Agree in advance with members how this will be handled.
Online or hybrid groups [synthesis; 6th ed. chapter not drawn on]. Set norms for private space, cameras and distractions. Treat connection drops and camera-off as process to be noticed, not only technical events.
