Personality / Styles

Somatizing Personality Style

A somatizing personality is one in which emotional pain tends to be lived through the body. Where another person might say “I’m frightened” or “I’m furious,” someone with this style is more likely to get a headache, a stomach that will not settle, exhaustion, or pain. The PDM-3 describes the body as the “preferential” means through which these people express painful experience (McWilliams & Shedler, 2026, p. 683).

Before anything else, two things need to be said plainly. First, the symptoms are real. Somatizing is not pretending, and it is not malingering. Nancy McWilliams writes that “the somatic experience of being emotionally unwell in ways that are unverbalizable is not equivalent to pretending to be ill,” nor does it mean a problem is “all in your head.” As she puts it, “The brain is a part of one’s physicality, not a detached overseer” (McWilliams, 2011, p. 117). The PDM-3 agrees that “the pain they suffer is real and debilitating” (McWilliams & Shedler, 2026, p. 684). Second, bodily symptoms always deserve a proper medical evaluation. The PDM-3 warns that some people labeled as somatizing turn out to have an undiagnosed illness, such as an autoimmune or infectious disease (McWilliams & Shedler, 2026, p. 683), and McWilliams cautions that concluding someone’s pain or exhaustion is somatization “should not be reached unreflectively”: illness itself can bring on regression, and people can become depressed because they are medically ill (McWilliams, 2011, p. 119). This page describes a personality pattern. It cannot tell anyone whether their own symptoms have a medical cause.

A bodily response to stress is also universal. “Our earliest reactions to the stresses of life are somatic,” McWilliams writes, and many remain with us: the fight–flight–freeze response, blushing with shame, the many ways the gut, skin, heart, and immune system respond to emotional pressure (McWilliams, 2011, pp. 117–118). In many cultures, expressing distress through the body is simply the normal language of suffering (McWilliams, 2011, p. 119). And the body’s sensitivity is not only a vulnerability: the PDM-3 describes healthy bodily awareness, the ability to notice and reflect on one’s bodily experience, as something that supports “mindful, adaptive decisions” (Lingiardi, Muzi & Bornstein, 2026, p. 719).

Everyone has a personality style, and most people have a blend. This page describes a pattern, not a verdict on anyone.

Style, Disorder, and the Space Between

The PDM-3 notes that somatization and bodily preoccupation occur across the whole severity range (McWilliams & Shedler, 2026, p. 683). Across the levels of organization, the pattern looks roughly like this:

When does a tendency become a disorder? McWilliams points out that the old DSM-IV diagnosis of somatization disorder described problems in many organ systems, over many years, in many circumstances, which is “pretty hard to differentiate conceptually from a personality disorder” (McWilliams, 2011, p. 118). For older adults, the PDM-3 lists warning signs that a personality pattern may be involved: complaints not tied to an identifiable disease, social withdrawal justified by physical difficulties, symptoms that fluctuate with particular situations or people, links between physical difficulties and major life events, and a history of many treatments for poorly defined ailments (Del Corno & Plotkin, 2026, p. 941). Even then, the PDM-3’s first instruction is to consider whether earlier medical workups missed something (Del Corno & Plotkin, 2026, p. 942). It also acknowledges that it can be hard to tell whether a self-focused, complaining manner in someone with puzzling, intractable ailments reflects a preexisting personality or the understandable psychological toll of chronic discomfort and “medical runarounds” (McWilliams & Shedler, 2026, p. 683).

The DSM has never included a somatizing personality disorder (McWilliams, 2011, p. 118; Del Corno & Plotkin, 2026, p. 940). The first PDM proposed one, and the PDM-3 keeps the category while acknowledging that “some scholars see somatizing presentations as outside the personality spectrum.” It also notes that a somatizing cluster did not emerge from SWAP research, perhaps because those studies sampled mainly from the caseloads of psychologists and psychiatrists (McWilliams & Shedler, 2026, p. 683). The symptom-level diagnoses are DSM-5-TR’s somatic symptom disorder and illness anxiety disorder, and ICD-11’s bodily distress disorder (Mundo, Muzi & Lingiardi, 2026, pp. 839–840).

Inner World

The central experience is of feelings that arrive as sensations rather than as emotions with names. The PDM-3 describes bodily symptoms as the result of “feelings and ideas, often negative, that are too intense to be expressed in words” (McWilliams & Shedler, 2026, p. 685). Many people with this style are notable for alexithymia, a term Sifneos introduced for an inability to express emotions verbally (McWilliams & Shedler, 2026, p. 684; Taylor et al., 2024). The PDM-3’s adolescent chapter adds an important nuance: in these young people, emotions are “not so much repressed or denied as never having been formulated” (Tanzilli & Sharp, 2026, p. 493).

Thinking tends to be concrete and repetitive, more invested in things than in imagination, a pattern French analysts called pensée opératoire, or operational thinking (McWilliams & Shedler, 2026, p. 684). These people may lack what Jurist calls “mentalized affectivity,” the capacity to make sense of one’s emotions in light of one’s own history (Tanzilli & Sharp, 2026, p. 493; McWilliams & Shedler, 2026, p. 684). Some also experience “somatosensory amplification,” in which bodily sensations feel unusually intense and disturbing (Mundo, Muzi & Lingiardi, 2026, p. 841). In the PDM-3’s mental functioning profile, these difficulties belong to the capacity for bodily experiences and representations; at a middling level of that capacity, whenever something threatening or unprocessed happens, “the body may become the focus of attention, self-expression, or concern” (Lingiardi, Muzi & Bornstein, 2026, p. 720). They also involve affect regulation and mentalization.

The sense of self tends to be fragile. People with this style may feel unentitled and powerless, and they often say they feel repeatedly unheard (McWilliams & Shedler, 2026, p. 684). The PDM-3 describes them as feeling “at the mercy of forces beyond their control” (McWilliams & Shedler, 2026, p. 685). In later life, thoughts of death and fears of physical or mental decline can become central (Del Corno & Plotkin, 2026, p. 941).

The pathogenic beliefs, in case-formulation terms, are relational as much as bodily. The PDM-3 suggests that the person’s inner model of relationships “may require them to be ill as a condition of being cared about” by someone important (McWilliams & Shedler, 2026, p. 684). In older adults it describes a belief that others have “inexhaustible resources of health, strength, and vitality,” so that unmet requests feel like hostility or indifference (Del Corno & Plotkin, 2026, p. 942).

Temperament and constitution are less well studied here than in other styles. McWilliams reports research linking somatization with alexithymia, insecure attachment, childhood trauma, childhood fear, and a less integrated sense of self, and notes that, contrary to common assumption, there is little evidence that parents cause it by paying attention to children’s symptoms (McWilliams, 2011, p. 118).

Defenses

The defining process is somatization, which McWilliams classes among the primary, or earliest, defensive processes (McWilliams, 2011, pp. 117–119). She notes that when young children are not helped to put feelings into words, they tend to express them either through depleted bodily states or through action (McWilliams, 2011, p. 117), and the PDM-3 cites Greenspan’s finding that children who cannot verbalize feelings tend either to act out or to get sick (McWilliams & Shedler, 2026, p. 684).

These are not choices. The PDM-3 distinguishes the “primary gain” of a symptom, the way it may spare a person from unbearable feeling, from “secondary gain,” such as attention or time off. Both are generally unconscious, and only conscious motives count as malingering (Mundo, Muzi & Lingiardi, 2026, pp. 840–841).

Relationships

Bodily concerns can come to fill the space where relationships would be. Describing somatic symptom disorder, the PDM-3 explains how preoccupation with the body “supplants in-depth relationships,” so that others become either sources of reassurance that never quite reassures, or people who drift away. Patients may seem desperate to connect with clinicians through their symptoms, perhaps repeating an insecure attachment pattern from childhood (Mundo, Muzi & Lingiardi, 2026, pp. 841–842).

A painful cycle often develops. People with this style feel unheard, partly because listeners tune out when their efforts to help are frustrated, and the PDM-3 suggests the unvoiced hatred interviewers often sense may come at least partly from years of being treated as annoying complainers and told “It’s all in your head” (McWilliams & Shedler, 2026, p. 684). Research with people living with chronic pain (a broader group than those with a somatizing style) found that preoccupied and fearful attachment styles were associated with more pain behavior, pain intensity, disability, and depressive symptoms, and secure attachment with less (Forsythe et al., 2012).

As for origins, the theories are about development, not blame. The PDM-3 suggests that early caregivers may not have fostered the capacity to represent feelings in words, “leaving their bodies to convey what their minds could not,” and that some may not have responded to the child’s communications (McWilliams & Shedler, 2026, p. 684). Its description of the bodily-experience capacity explains why this matters: when an infant’s bodily experience can be held in a caregiver’s mind, the child develops a coherent sense of self rooted in the body; developmental interferences such as early trauma can leave meanings that remain in the body because they cannot be put into fantasies or words (Lingiardi, Muzi & Bornstein, 2026, p. 719). The adolescent chapter notes that the relational experiences behind the symptoms are often traumatic (Tanzilli & Sharp, 2026, p. 494).

In Therapy

Transference is the set of expectations from earlier relationships that a person brings to the therapist. Countertransference is the therapist’s emotional response. Both matter a great deal with this style.

People with a somatizing style often come to therapy only reluctantly. Many arrive after a series of “defeated medical specialists” has sent them, resentful and expecting to be accused of malingering (McWilliams & Shedler, 2026, p. 684). McWilliams notes that their suffering is often complicated by having already met “impatience, exasperation, and a sense of defeat” in previous professionals (McWilliams, 2011, p. 119). With clinicians they may seem both helpless and oppositional (McWilliams & Shedler, 2026, p. 684), and in therapy they may expect yet another authority who does not really listen, feeling disbelieved or blamed when the therapist explores meanings beyond the medical (Mundo, Muzi & Lingiardi, 2026, p. 842). McWilliams notes that people who have repeatedly been treated like spoiled children or attention seekers understandably build a wall of defensiveness, so the therapist needs “almost superhuman reserves of tact and patience” (McWilliams, 2011, p. 131).

Therapists commonly feel futility, impatience, irritation, boredom, inner deadness, and disengagement (McWilliams & Shedler, 2026, p. 684). The PDM-3 notes that these feelings often mirror the patient’s own difficulty with feelings (Mundo, Muzi & Lingiardi, 2026, p. 842). Recognizing them as information, rather than acting on them, is part of the work.

What tends to help is clear and consistent across the sources. The PDM-3 says that “empathic observation that their suffering is real is critical to therapeutic progress”; without it, patients may feel accused of manufacturing their pain (McWilliams & Shedler, 2026, pp. 684–685). McWilliams recommends starting not with the feelings presumed to lie behind a symptom but with the feelings the symptom itself causes, for instance, “I can’t even imagine how depressing and exasperating it is to be in physical pain most of the time.” Moving too quickly to find emotions “underneath” the pain, she warns, will likely be heard as an accusation (McWilliams, 1999, p. 112). Over time, therapists tactfully encourage the person to feel, name, and accept emotional states (McWilliams & Shedler, 2026, p. 685), patiently helping them name feelings that were never formulated; with adolescents, the PDM-3 recommends exploratory psychodynamic therapy that helps turn bodily sensations and malaise back into emotions, while noting that a young person in pain may still, understandably, seek the therapist’s reassurance about physical worries (Tanzilli & Sharp, 2026, p. 493). McWilliams writes that the alexithymic patient, “who seems to take forever to make the slightest progress,” is still learning in that slowness “that feelings have names that can be spoken aloud and shared with another person” (McWilliams, 2004, p. 245).

What tends to backfire: persuading the person too early that the problem is psychological, which the PDM-3 calls an enactment that confirms their fear of not being taken seriously (Tanzilli & Sharp, 2026, p. 493), and focusing narrowly on secondary gain, which leaves people feeling accused (Mundo, Muzi & Lingiardi, 2026, p. 841). Because any movement toward feeling is stressful, people often become ill and cancel just when progress begins (McWilliams & Shedler, 2026, p. 685). Addiction to prescribed pain medication is a common complication (McWilliams & Shedler, 2026, p. 684). With older adults, the PDM-3 urges clinicians to resist the temptation to disengage from persistent complaints, reminding them that whatever its psychological origins, “the patient’s suffering is real,” and that finding a previously missed physical problem can bring relief to everyone involved (Del Corno & Plotkin, 2026, p. 942).

The evidence is encouraging. Although there is little research on somatizing personality, the PDM-3 cites many studies showing relief of pervasive bodily symptoms through psychotherapy (McWilliams & Shedler, 2026, p. 683). It also points to Deutsch’s “associative anamnesis,” a gentle, nonconfrontational exploration of a symptom that often leads to the relevant losses, conflicts, or traumas (Mundo, Muzi & Lingiardi, 2026, p. 840).

Variations

The PDC-3 lists the somatizing style without subtypes (Gordon & Bornstein, 2025). The literature nonetheless describes several forms:

The style blends with others. In the dependent style, illness can become a bid for care at more troubled levels, and counterdependent people may have a tendency toward illness or injury that gives them a “legitimate” reason to be cared for (McWilliams & Shedler, 2026, pp. 673, 675). The anxious–avoidant prototype includes stress-related bodily symptoms and worry about aches and pains (McWilliams & Shedler, 2026, p. 678). Conversion links it historically to the hysterical–histrionic style, and in later life it may mask a depressive state (Del Corno & Plotkin, 2026, p. 941).

How Different Thinkers See It

Freud and Breuer: conversion

Freud coined the term “conversion” in 1894 to describe how, in hysteria, a disturbing idea is made harmless by turning its emotional charge “into something somatic” (Mundo, Muzi & Lingiardi, 2026, pp. 837–838). His case histories in Studies on Hysteria, written with Breuer, traced bodily symptoms to painful feelings that could not be admitted to awareness (Freud, 1909, pp. 31–74). McWilliams notes that when many physicians dismissed women with conversion and somatization problems as “frivolous malingerers,” Freud took them seriously and tried to understand them (McWilliams, 2004, p. 35).

Jurgen Ruesch: the “infantile personality”

In a 1948 paper subtitled “the core problem of psychosomatic medicine,” Ruesch described unimaginativeness and limited verbal and symbolic expression of emotion among patients with “psychosomatic” diseases and posttraumatic syndromes (Ruesch, 1948; Taylor et al., 2024). The term “infantile personality” has had a confusing afterlife. McWilliams uses it for people whose core strategy is regression and notes that the category “did not survive after the second edition of the DSM” (McWilliams, 2011, p. 131). Kernberg later used “infantile personality” for something different, the lower-functioning end of the hysterical spectrum (McWilliams, 2011, p. 312).

The Paris psychosomatic school: operational thinking

Marty and de M’Uzan described patients with physical illnesses whose thinking was strikingly empty of fantasy, unable to use symbols, and invested in things rather than imagination. They called this la pensée opératoire (McWilliams & Shedler, 2026, p. 684), and their observations helped inspire the later concept of alexithymia (Taylor et al., 2024).

Sifneos, Nemiah, and the Toronto group: alexithymia

Nemiah and Sifneos, studying patients with “classic” psychosomatic diseases, described the cluster Sifneos named alexithymia (Sifneos, 1973). Sifneos did not think it was specific to psychosomatic illness and expected to find it in addiction and some personality disorders too. Graeme Taylor, Michael Bagby, and colleagues at the University of Toronto later developed the widely used Toronto Alexithymia Scale. As they summarize the construct, it has four components: difficulty identifying feelings and telling them apart from the bodily sensations of emotion, difficulty describing feelings, constricted imagination, and an externally oriented style of thinking. They treat alexithymia as a dimensional, relatively stable trait. A Finnish study of more than 5,000 adults found alexithymia associated with somatization independently of physical disease, depression, and anxiety (Taylor et al., 2024).

McDougall: theaters of the body

McDougall’s Theaters of the Body (1989) gave a psychoanalytic account of psychosomatic illness, and the PDM-3 cites her for the idea of a personality “tilt toward expressing dysphoria through the body” (McWilliams & Shedler, 2026, p. 683). McWilliams draws on her to stress that a therapist must first appreciate what McDougall called “inexpressible pain and fears of a psychotic nature,” such as the fear of losing one’s sense of identity (McWilliams, 1999, p. 112).

George Engel: the biopsychosocial model

Engel argued that the dominant biomedical model “leaves no room within its framework for the social, psychological, and behavioral dimensions of illness,” and proposed a biopsychosocial model instead (Engel, 1977). His framework supports the stance this page takes: body, mind, and relationships are not rival explanations but parts of one system.

Mentalization and affect research

Contemporary psychodynamic writers frame somatizing as a problem of representing feeling. The PDM-3 cites Lane and colleagues’ term “affective agnosia,” Jurist’s “mentalized affectivity,” and Stern’s emphasis on naming “unformulated” affect (Tanzilli & Sharp, 2026, p. 493; McWilliams & Shedler, 2026, p. 684). In this view the work of therapy is not uncovering hidden feelings but helping them take shape for the first time.

The DSM and ICD

The manuals have moved away from the question “is it medically explained?” DSM-5-TR’s somatic symptom disorder focuses on distressing symptoms and the person’s thoughts, feelings, and behavior about them (Mundo, Muzi & Lingiardi, 2026, p. 839). ICD-11’s bodily distress disorder likewise centers on bodily symptoms that distress the person and on excessive attention to those symptoms, rather than on whether the symptoms are medically explained (Gureje & Reed, 2016). Neither treats the pattern as personality.

Examples

Elisabeth von R.

In one of the cases in Studies on Hysteria, Freud describes a young woman who had suffered for over two years from pains in her legs and difficulty walking, after years of nursing sick family members through a series of losses. Freud thought there was probably a real muscular, rheumatic basis for her early pains, which the later symptoms then “markedly exaggerated” and imitated. Over the treatment, Freud traced the pains to feelings she could not allow herself to know about. Afterward she was reported to be well, apart from occasional slight pains. Freud later saw her, by chance, “gliding along in a rapid dance.” The case is a historical example of conversion, and a reminder that even Freud assumed a physical component.

Sigmund Freud, Selected Papers on Hysteria and Other Psychoneuroses (1909), pp. 31–74

Molly’s stomach

McWilliams describes a patient, Molly, who as a child was “mildly school phobic”: on Sunday afternoons she would become increasingly anxious, sick to her stomach, and panicky about leaving home the next day. As a teenager she was hospitalized with severe hepatitis, which was diagnosed late “because her mother had insisted that she was malingering.” The two episodes together show both sides of this page: emotional stress felt in the body, and a serious illness missed because someone assumed she was faking.

Nancy McWilliams, Psychoanalytic Psychotherapy (2004), p. 204

The patient sent by defeated doctors (a typical scenario)

The PDM-3 and McWilliams both describe a familiar clinical situation in general terms; it is a typical pattern, not a particular person’s case. A person with chronic pain or other intractable symptoms consults a therapist “reluctantly and in desperation,” at the urging of physicians who have run out of ideas. They arrive resentful and braced to be told they are making it up (McWilliams & Shedler, 2026, p. 684). McWilliams’s advice for the first meeting is to begin with compassion for what the physical suffering itself is like, not with a search for hidden emotions, because the person “has probably received exactly this message from a series of defeated physicians.” She adds elsewhere that therapists see many clients referred by physicians “who have been defeated by a patient’s chronic physical fragility.”

Lingiardi & McWilliams (Eds.), PDM-3 (2026), p. 684; Nancy McWilliams, Psychoanalytic Case Formulation (1999), p. 112; Nancy McWilliams, Psychoanalytic Diagnosis (2011), p. 118

How It Differs From Look-Alikes

Hypochondriasis (illness anxiety)
McWilliams explains that in hypochondriasis there is no disease process, despite the worry or even conviction of illness, while in somatization there are real ailments related to stresses the person cannot process emotionally (McWilliams, 2011, p. 131). The PDM-3 calls hypochondriasis a more severe condition, with exaggerated fears of illness, rituals around the body, and bodily preoccupation taking the place of relationships (McWilliams & Shedler, 2026, p. 684).
Malingering and factitious illness
These involve consciously producing or feigning symptoms (Mundo, Muzi & Lingiardi, 2026, p. 839). Somatizing does not (McWilliams, 2011, p. 117). The PDM-3 reserves the word malingering for conscious motives such as getting off work (Mundo, Muzi & Lingiardi, 2026, p. 841).
Undiagnosed physical illness
McWilliams urges therapists to “leave open a mental space for the possibility” that a difficult patient who seems clearly hypochondriacal or somatizing has an unidentified systemic illness (McWilliams, 2011, p. 131). She notes that symptoms of illnesses such as multiple sclerosis have often been misread as psychological, and, writing about people with hysterical tendencies, that pursuing a possible physical cause “sends a therapeutic message to a scared human being whose basic dignity has not always been respected” (McWilliams, 2011, p. 330). She even warns therapists about misreading their own symptoms this way (McWilliams, 2004, p. 288). Literature knows the pattern too: in Austen’s Emma, Mrs. Churchill’s illnesses are long dismissed as fancy until her sudden death “acquitted her of all the fancifulness, and all the selfishness of imaginary complaints” (Austen, 1815, Vol. III, Ch. 9).
Cultural idioms of distress
In cultures where suffering is normally expressed through the body, even psychologically mature people speak this way, and assuming a regressive process is unwarranted (McWilliams, 2011, p. 119). McWilliams chose not to write a full chapter on somatizing personalities partly to avoid pathologizing such cultures (McWilliams, 2011, p. xiii). The PDM-3 adds that the tendency to experience and communicate distress through the body, and to seek medical care for it, is universal, and that cultural, social, and economic factors shape it; somatic complaints are more likely, for example, where clinical visits are brief and care is less person-centered (Mundo, Muzi & Lingiardi, 2026, p. 840).
Conversion and the hysterical–histrionic style
The PDM-3 distinguishes la belle indifference, a puzzling calm about disabling conversion symptoms, from the broader alexithymia and operational thinking of somatizing personalities (Mundo, Muzi & Lingiardi, 2026, p. 838). Today conversion is diagnosed as functional neurological symptom disorder (DSM-5-TR) or dissociative neurological symptom disorder (ICD-11) (Mundo, Muzi & Lingiardi, 2026, p. 838).
Masked depression and narcissistic fragility
In older adults, somatizing can defend against depression and should be distinguished from it (Del Corno & Plotkin, 2026, p. 941). In narcissistic personalities, fear of the self fragmenting is often displaced onto worry about physical health (McWilliams, 2011, p. 185).

History

The psychoanalytic story begins with hysteria. Freud introduced the idea of conversion in 1894, and with Breuer published Studies on Hysteria (1893–1895), case histories in which bodily symptoms were traced to feelings that could not be admitted (Mundo, Muzi & Lingiardi, 2026, pp. 837–838; McWilliams, 2011, p. 128; Freud, 1909). Conversion became the paradigm of a symptom as compromise, and later the official psychiatric category of conversion disorder (Mundo, Muzi & Lingiardi, 2026, pp. 837–838).

In broad terms, mid-twentieth-century psychosomatic researchers turned from the symbolic meaning of particular symptoms to a broader way of experiencing, or not experiencing, emotion. Ruesch described the “infantile personality” in 1948 (Ruesch, 1948); Marty and de M’Uzan described operational thinking in 1963 (McWilliams & Shedler, 2026, p. 684); Sifneos named alexithymia in the early 1970s (Sifneos, 1973; Taylor et al., 2024). In 1977 Engel proposed the biopsychosocial model as an alternative to a purely biomedical one (Engel, 1977).

The psychiatric manuals took a different path. Somatization disorder, descended from “Briquet’s syndrome” and defined by a high count of symptoms across body systems, ran from DSM-III to DSM-IV-TR. DSM-5 replaced it with somatic symptom disorder and dropped the requirement that symptoms be medically unexplained, partly because people found the old diagnoses demeaning, as if their symptoms were not “real” (Mundo, Muzi & Lingiardi, 2026, p. 839). ICD-11 created bodily distress disorder, which absorbed most of the old somatoform categories, and moved hypochondriasis to the obsessive–compulsive and related disorders (Gureje & Reed, 2016; Mundo, Muzi & Lingiardi, 2026, p. 842).

The first PDM (2006) proposed a somatizing personality disorder (McWilliams, 2011, p. 118; McWilliams & Shedler, 2026, p. 683). McWilliams expanded her discussion of somatization in 2011 at the urging of colleagues from cultures where suffering is often expressed through the body, while choosing not to give it a full chapter, and referred readers to the PDM (McWilliams, 2011, p. xiii). The PDM-3 keeps the somatizing personality as a clinically derived description, without an empirical prototype, and with developmental versions for adolescents and older adults (Tanzilli & Sharp, 2026, pp. 493–494; McWilliams & Shedler, 2026, pp. 683–685; Del Corno & Plotkin, 2026, pp. 940–942).
