The triangle of conflict is a map therapists use to understand what happens emotionally beneath the surface when someone feels stuck, anxious, or physically unwell without a clear medical cause. Originally formulated by the British psychoanalyst David Malan, the model identifies three interconnected corners: an underlying feeling (such as anger, grief, or longing), the anxiety that feeling triggers, and the defenses a person uses to avoid both the feeling and the anxiety. The concept became central to several forms of short-term psychodynamic therapy and has since been applied to populations ranging from adults with treatment-resistant depression to children with disruptive behavior problems.
Three Corners, One Emotional Loop
The triangle of conflict captures a pattern that repeats across nearly every presenting problem therapists encounter. At the bottom sits an underlying emotion, sometimes called the “true feeling” or “impulse.” This can be rage toward a parent, sadness over a loss, tenderness toward someone who feels dangerous to love, or any other feeling that was punished, ignored, or overwhelming in a person’s early life. Affect-phobia therapy, one treatment built directly on Malan’s framework, describes this corner as the experience or expression of feelings that the person learned to block.
The second corner is anxiety. When the buried feeling starts to surface, the nervous system responds as though something threatening is happening. This anxiety is not the free-floating kind people associate with generalized worry. It is specifically triggered by the approach of the forbidden feeling, almost like a conditioned alarm. Researchers have described this combination of emotions plus conditioned anxiety from disrupted early attachment as a recipe for what they call “dysregulated affective states,” where the person’s emotional system spirals instead of processing the feeling cleanly.
1Frontiers in Psychology. Dysregulated Anxiety and Dysregulating Defenses: Toward an Emotion Regulation Informed Dynamic PsychotherapyThe third corner is defense. Defenses are the habitual strategies people use to keep the feeling and its accompanying anxiety out of awareness. These range from obvious avoidance (changing the subject, going blank, intellectualizing) to subtler patterns like sarcasm, compliance, or smiling while describing something painful. In the triangle’s logic, the defense is not the problem itself but a solution the person found early in life that now costs more than it saves. The therapeutic goal is not to strip defenses away but to make them visible so the person can choose whether to keep using them.
Malan’s framework links these three corners in a specific causal chain: a feeling arises, anxiety signals danger, and a defense kicks in to shut both down. Therapists trained in this model learn to listen for all three simultaneously. When a client suddenly changes the subject mid-sentence, the therapist hears a defense. When a client reports chest tightness while discussing a parent, the therapist sees anxiety. The question always becomes: what feeling is underneath?

One of the more striking features of the triangle of conflict is how literally the anxiety corner can manifest. Habib Davanloo, who built Intensive Short-Term Dynamic Psychotherapy (ISTDP) on Malan’s framework, spent decades studying video recordings of therapy sessions and catalogued three distinct physical pathways that anxiety takes in the body.
The first pathway runs through the striated muscles, the voluntary muscles you use to move your limbs. When unconscious anxiety channels into striated muscle, the result can be tension headaches, back pain, jaw clenching, tremors, tics, and conditions like fibromyalgia. Davanloo observed that these symptoms often intensified at precisely the moments when a buried feeling was closest to the surface in a session.
3PubMed Central. Intensive Short-Term Dynamic Psychotherapy for Functional Somatic Disorders: A Scoping ReviewThe second pathway involves smooth muscle, which controls involuntary functions like digestion and breathing. Anxiety channelled here can produce irritable bowel symptoms, nausea, breathing difficulties, or bladder urgency. The third pathway is cognitive-perceptual disruption: when anxiety overwhelms both muscle systems, a person may experience dizziness, tunnel vision, or a feeling of unreality. In ISTDP, recognizing which pathway a patient’s anxiety takes is a diagnostic step that determines how quickly the therapist can push toward the underlying feeling. A patient whose anxiety runs through striated muscle is generally considered more resilient than one whose anxiety disrupts cognitive functioning, because striated-muscle anxiety means the body is containing the distress in a way that, while painful, doesn’t impair thinking.
This framework helps explain why many people with chronic pain, gastrointestinal problems, or neurological symptoms that defy medical explanation end up in psychodynamic therapy. What looks like a body problem is, through the lens of the triangle, an anxiety problem, and the anxiety is in turn a feeling problem.
The Companion Model: the Triangle of Person
Malan designed the triangle of conflict to sit alongside a second triangle, known as the triangle of person. Where the triangle of conflict maps what is happening emotionally (feeling, anxiety, defense), the triangle of person maps where it is happening relationally. Its three corners are past persons (usually a parent or early caregiver), current persons (a partner, boss, friend), and the therapist.
4PeerJ. Affect-focused psychodynamic psychotherapy for depression and anxiety through the Internet: a randomized controlled trialThe idea is straightforward: the emotional pattern described by the triangle of conflict did not develop in a vacuum. It began in a specific relationship, usually in childhood. The child who learned that showing anger at a parent led to rejection, for example, developed a defense (suppressing anger), fueled by anxiety (fear of being abandoned), to avoid the underlying feeling (rage). That same pattern now replays with a demanding boss or an intimate partner. And, critically, it shows up live in the therapy room, where the therapist can observe it directly rather than just hearing about it secondhand.
Therapists use the two triangles together as a kind of GPS. The triangle of conflict tells them what emotional maneuver just happened, and the triangle of person tells them who it is about. A client who goes intellectually blank (defense) while feeling tension in their neck (anxiety) when the therapist asks about their father (past person) has just demonstrated both triangles in a single moment. The therapist’s job is to name all of that, gently, and invite the client to stay with the feeling rather than escape through the defense.
What Happens in a Session Built Around the Triangle
In therapies that explicitly use the triangle of conflict, sessions tend to follow a recognizable rhythm. The therapist listens for the defense first. That might be vagueness, storytelling that keeps circling without landing, or emotional flattening. Once the defense is spotted, the therapist names it or draws the client’s attention to it, often by simply describing what they see: “I notice you smiled just now while telling me something that sounds quite painful.”
The next step is to track the anxiety. If the client drops the defense, even briefly, their body typically responds. The therapist monitors for signs of rising anxiety and helps the client tolerate it rather than retreating back into the defense. This is the hinge point of the model: if the client can stay with the anxiety long enough, the underlying feeling tends to surface on its own.
The feeling, when it arrives, is often intense and surprising. Someone who came in complaining of chronic stomach pain may find themselves sobbing about a sibling they lost years ago. Someone who presented with social withdrawal may discover a fury they never knew they carried. The therapeutic assumption is that experiencing the feeling directly, rather than routing it through anxiety and defense, is what produces lasting change. A randomized trial of ISTDP for social anxiety disorder found that the therapy was effective compared to a control group. Interestingly, the study also compared a version of ISTDP that emphasized working directly with feelings against a version that emphasized analyzing defenses, and found no significant difference in outcomes between the two approaches. Both routes through the triangle led to the same destination.
5The Journal of Nervous and Mental Disease. The Efficacy of Intensive Short-Term Dynamic Psychotherapy for Social Anxiety Disorder: Randomized Trial and Substudy of Emphasizing Feeling Versus Defense WorkThis finding makes sense within the model. Whether you help someone recognize and drop a defense or help them go straight to the buried emotion, you are disrupting the same loop. The triangle of conflict is one system; loosening any corner eventually affects the other two.
The Evidence for Treatments Built on This Framework
The triangle of conflict is a clinical concept, not a standalone treatment, but the therapies that use it as their organizing principle have accumulated a growing evidence base. ISTDP, the most researched of these, has been evaluated in more than 50 publications for its effects on functional somatic disorders alone, showing efficacy across chronic pain, functional gastrointestinal disorders, and functional neurological conditions.
6PubMed Central. Intensive Short-Term Dynamic Psychotherapy for Functional Somatic Disorders: A Scoping ReviewFor medically unexplained pain specifically, a randomized trial comparing ISTDP to cognitive-behavioral therapy found that ISTDP offered an effective alternative, with researchers concluding it could serve patients whose pain had no identifiable physical cause.
7PubMed. Psychotherapy for Medically Unexplained Pain: A Randomized Clinical Trial Comparing Intensive Short-Term Dynamic Psychotherapy and Cognitive-Behavior TherapyDepression has also been a focus. In a trial targeting treatment-resistant depression, patients who received ISTDP showed moderate to large improvements compared to treatment as usual, with effect sizes of 0.75 on clinician-rated measures and 0.85 on self-report measures. After six months, about a third of those in the ISTDP group achieved complete remission, compared to fewer than one in twenty of those receiving standard care. Roughly half of the ISTDP group reached at least partial remission.
8PubMed Central. A randomised controlled trial of Intensive Short-Term Dynamic Psychotherapy for treatment resistant depression: the Halifax Depression StudyThese are meaningful numbers for a population that, by definition, had already failed to respond to prior treatments. The triangle of conflict gives therapists a theory for why treatment-resistant depression might respond to this approach: if the depression is maintained by a defense against unbearable feelings, and those feelings are generating chronic anxiety that keeps the whole system locked, then addressing the feeling directly could break a cycle that antidepressants and standard talk therapy did not touch.
Does Emotional Depth Actually Predict Improvement?
A reasonable question about the triangle of conflict is whether emotional experiencing, the bottom corner of the model, actually matters for outcomes or whether it is just a theoretical preference. Process-outcome research has tried to answer this. One study of therapy with young people measured the depth of emotional experiencing during sessions using a standardized scale and found that it accounted for a meaningful share of improvement. After controlling for how distressed the young person was at the start, the depth of their emotional experiencing in working sessions predicted their improvement, explaining about 12% of the variance in symptom change.
9PubMed Central. Depth of emotional experiencing and outcome in therapy with young peopleTwelve percent might not sound dramatic, but in psychotherapy research, where outcomes depend on dozens of overlapping factors, a single process variable rarely accounts for more than about 15% of change. The finding supports the triangle’s central claim: getting to the feeling matters. It is not just a theoretical nicety. Clients who reach deeper emotional experiencing, rather than staying at the level of defense or intellectualization, tend to get more out of therapy.
Adapting the Triangle for Children
One challenge with the triangle of conflict is that it was developed with adults in mind. Adults can, with help, observe their own defenses, name their anxiety, and identify underlying feelings. Children, especially young children with behavioral problems, communicate through action rather than words. A child who is disruptive, aggressive, or defiant is unlikely to sit down and examine their defense mechanisms.
A recently described adaptation called Regulation-Focused Psychotherapy for Children (RFP-C) addresses this by flipping the triangle’s clinical use. Instead of helping the patient observe their own triangle, RFP-C uses the triangle of conflict as a tool for the therapist and the child’s parents. The clinician uses the model to reflect on their own emotional reactions to the child’s behavior, a concept known as countertransference, and to guide parents toward curiosity about what emotions might be driving their child’s actions rather than simply trying to suppress the behavior.
10PubMed. The RFP-C Triangle of Conflict: Listening to Countertransference Helps Listening to Children With Disruptive BehaviorsFor example, a child who throws things in the therapist’s office (defense) may be showing anxiety about separation from a parent, with the underlying feeling being grief or rage about an absent caregiver. The child cannot articulate this. But the therapist, using the triangle, can hypothesize it, notice their own frustration (countertransference), use that frustration as clinical data, and help the parents see the behavior as an emotional communication rather than simple defiance. RFP-C is described as the first manualized psychodynamic treatment specifically designed for children with disruptive behaviors, and its use of the triangle demonstrates how flexible the model can be when adapted thoughtfully.
What Brain Imaging Suggests About the Mechanism
The triangle of conflict makes a specific claim about how emotional change works: experiencing a previously avoided feeling, rather than just understanding it intellectually, is what produces lasting shifts. Neuroimaging research has offered partial support for this idea, though the picture is more complex than early models predicted.
Influential neurobiological models of how psychotherapy works assumed the mechanism was top-down: prefrontal brain regions, associated with conscious control, would increase their activity and dampen the limbic system, the brain’s emotional alarm center. This would amount to strengthening the defense corner of the triangle by giving the rational brain more control over emotional responses. But meta-analyses of neuroimaging studies of psychotherapy’s effects, along with research on implicit emotion regulation, suggest something different. Areas involved in coding meaning, in understanding what emotions signify rather than simply suppressing them, appear to play a role that existing top-down models do not account for.
11Springer Link. Changing views of emotion regulation and neurobiological models of the mechanism of action of psychotherapyThis is more consistent with the triangle of conflict’s framework than it might first appear. The model does not propose that people learn to suppress their feelings more effectively. It proposes that they learn to feel what they actually feel, make meaning of it, and stop needing the defense. The neuroimaging data suggesting that semantic processing regions, not just executive control regions, are central to emotional change aligns with that claim. You do not get better by getting better at shutting feelings down; you get better by understanding what they mean and experiencing them fully enough to move through them.
Common Misconceptions About the Model
The triangle of conflict is frequently misunderstood, both by people encountering psychodynamic ideas for the first time and occasionally by therapists trained in other traditions. A few misconceptions come up repeatedly.
The first is that the model pathologizes all defense. It does not. Defenses exist because they were once adaptive. A child who learned to go numb in the face of an abusive parent was protecting themselves in the only way available. The triangle’s point is not that defenses are bad but that some defenses outlive their usefulness and begin creating more suffering than the feelings they guard against. A well-timed joke to lighten tension at dinner is a defense, and nobody needs therapy for it. Chronic emotional numbness that prevents intimacy for decades is the same category of defense applied in a context where it no longer serves the person.
The second misconception is that the model is purely about catharsis, that the goal is simply to make people cry or rage in a therapy session. The emotional experiencing the triangle points toward is not the same as emotional venting. Venting without connection to the underlying feeling and its relational context (the triangle of person) can actually reinforce defenses rather than resolving them. The person feels drained after a session but nothing has shifted. What the model aims for is specific emotional experiencing tied to specific relationships, with the anxiety tolerated rather than avoided, and with the defense recognized and set aside voluntarily.
A third misconception is that the triangle applies only to people with severe or complex psychological problems. In reality, the pattern it describes is universal. Everyone has feelings they find uncomfortable, anxiety triggered by those feelings, and habitual ways of avoiding both. The triangle becomes clinically relevant when the cycle is rigid enough to cause symptoms or impair functioning, but the underlying dynamic is part of normal emotional life.
The Triangle Outside Traditional Therapy
While the triangle of conflict was designed for psychotherapy, its logic has been borrowed by fields outside the consulting room. In executive coaching, for instance, practitioners navigate a “triangular relationship” between themselves, the individual being coached, and the organization paying for the coaching. Researchers studying this dynamic have noted the ethical ambiguities that arise and have proposed frameworks to help coaches manage the inherent tensions, drawing on models originally developed for other relational triangles in professional settings.
12BAR – Brazilian Administration Review. Drawing the Triangle: How Coaches Manage Ambiguities Inherited in Executive CoachingThis is a different kind of triangle, of course. The executive coaching version involves role conflicts among three parties rather than the intrapsychic conflict between feeling, anxiety, and defense. But the borrowing is not accidental. Any situation where competing pressures create internal tension for a person can be loosely mapped using a three-cornered model. The popularity of triangular thinking across disciplines reflects something genuinely useful about the format: three elements in tension are simple enough to hold in your mind, complex enough to capture real dynamics, and specific enough to guide action. Whether the corners are labeled “feeling, anxiety, defense,” “child, therapist, parent,” or “coach, client, organization,” the triangle gives the person using it a way to ask: which corner am I neglecting, and what would happen if I turned toward it?
