During the same few decades
which saw great advances in the understanding of placebos,
psychosomatic medicine also underwent significant changes, both in
the research and clinical field and in the wider area of popular
interest. The most important changes centered on the virtual
abandonment of ideas about the role of unconscious emotions, early
childhood experiences, and personality peculiarities--all derived
from psychoanalysis. These ideas were replaced by a focus on
manifest emotions, current life situations, and the
socio-environmental circumstances in which disease occurred. 46
Scientists often stated the newer formulations in terms of
maladaptation and loss or, more commonly, "stress" and
"deprivation." Researchers drew from physiological theory and
experiment and extended their concepts to all diseases, not just the
classic "psychosomatic seven" (which included peptic ulcer, asthma,
hypertension and, depending on the psychosomatic texts, colitis,
cardiac arrhythmia, neurodermatitis, and hyperthyroidism). Yet at
the same time scientists broadened the range of emotion-disease
connections, the once almost unquestioned presumption of psychogenic
etiology for the "psychosomatic" diseases gave way to an
increasingly somatic orientation. In the realm of therapy and
disease management, individual psychotherapy was replaced by stress
reduction, structured mobilization against feelings of loss and
loneliness, and increased reliance on the therapeutic options of
biomedicine.
The decline in the medical
popularity of psychoanalysis, evident in the late 1950s and
continuing in the 1960s and 1970s, set many of these changes in
motion. 47
Leading researchers submitted analytically-based theories of peptic
ulcer, asthma and ulcerative colitis to searching criticism and
substantial revision. Therapeutic approaches relied more and more on
new drugs and medical interventions and less and less on
psychodynamic psychotherapy. 48
In the most dramatic case, scientists recently attributed the cause
of peptic ulcer to a spiral bacterium, best managed clinically with
antibiotics. This new movement even attacked conversion
hysteria--one of the major contributions of Freud and a mainstay of
psychosomatic theory. Several important critics started picking at
the loose and unreflective consensus that had come to surround
symbolically interpreted hysteria. One of the most influential
critics, the respected neurologist Eliot Slater, in a widely noted
paper published in 1965, called the diagnosis of conversion hysteria
"a disguise for ignorance and a fertile source of clinical error."

Walter
Bradford Cannon
|
Taught to deal with concrete and demonstrable
bodily changes, we are likely to minimize or neglect the influence
of an emotional upset, or to call the patient who complains of it
"neurotic", perphaps tell him to "go home and forget it," and then
be indifferent to the consequences. But emotional upsets have
concrete and demonstrable effects in the organism.

Walter Bradford Cannon (1871 - 1945)Bodily
Changes in Pain, Hunger, Fear and Rage: An Account of Recent
Researches into the Functions of Emotional Excitement, New York,
1915 |
This discrediting of
psychoanalysis created a widening gap in psychosomatic thought that
was steadily filled by a variety of theoretical alternatives. These
concepts rested on more directly observable and less arcane linkages
between emotions and the onset of disease. However much these
theoretical alternatives differed, they had in common a
psychobiological orientation, in the sense that they were clearly
based on notions of holistic body and mind response of the total
human organism to various stimuli, threats and assaults from its
environment. A common origin explained the similar orientation of
these new theoretical approaches, for they all derived in some sense
from the fundamental work of early twentieth century Harvard
physiologist Walter B. Cannon. Cannon’s general program was to show
how the biological organism automatically mobilized its
physiological and biochemical resources by a built-in "wisdom of the
body," to defend itself against real or threatened assault. As an
example of defensive mobilization, he explained in Bodily Changes
in Pain, Hunger, Fear and Rage (1915), the organism responds to
fear and rage as though preparing for fight or flight, by shutting
down energy-storing functions and activating energy-releasing ones.
In the 1940s, psychosomatic investigator Harold G. Wolff and his
associates at Cornell Medical School incorporated many of Cannon’s
ideas. 50
Wolff then moved from a model of organismic self-defense directly
borrowed from Cannon to a generalized notion of "stress and
disease," according to which disease was the "inept" version of a
normally "apt protective reaction pattern" that allowed the human
organism to mobilize against stressful situations or events. 51

Hans
Selye The Physiology and Pathology of Exposure to
Stress, Montreal, 1950 |
|
Stress became a leading new
idea in psychosomatic theory in the 1950s and Hans Selye emerged as
its best known and most effective proponent. Selye was a
Vienna-born, Prague-trained physician and biochemist who settled in
Montreal in the 1930s and wrote the leading endocrinology textbook
in 1947. In 1950 he published a 1,025-page monograph entitled The
Physiology and Pathology of Exposure to Stress, in which he
elaborated ideas he had been developing since 1936 on what he called
the "General Adaptation Syndrome." 52
Selye’s theory was that various "stressors" (cold, heat, solar
radiation, burns, "nervous stimuli") produce a generalized,
stereotyped response in the biological organism as it works to
"perform certain adaptive functions and then to reestablish
normalcy." As the organism automatically mobilizes its defense
mechanisms, the hypothalamus (a nerve center at the base of the
brain) is excited first. Later, after a chain of effects, the
adrenal glands produce "corticoid" hormones. Corticoid hormones
cause a characteristic set of somatic reactions including the
development of gastrointestinal ulcers.
|
Due largely to their
synthetic scope, Selye’s ideas swept the field and exerted an
enormous influence. As F.L. Engel noted in 1956, "(Selye’s theory of
stress and the diseases of adaptation) has permeated medical
thinking and influenced medical research in every land, probably
more rapidly and more intensely than any other theory of disease
ever proposed." 53
The "stress syndrome" became even more popular and widely known in
the sixties, partly because of its appeal as a replacement for
older, increasingly discredited psychoanalytically-based
psychosomatic theories and partly due to Selye’s charisma and
prodigious output. He published forty books and over 1,700
scientific papers in the course of his career. 54
Selye was frequently quoted throughout medicine, nursing, and other
health fields, and his fame spread to the wider culture, a
reputation he deliberately cultivated by publishing such books for
the general reader as The Story of the Adaptive Syndrome
(1952), The Stress of Life (1956 and 1976), and Stress
Without Distress (1974). Yet by the 1970s there was discord in
the field of stress research as Selye conceived it. Growing
confusion and controversy riddled theory and experiment. Some
critics blamed Selye for having caused a great deal of it with his
conceptual inconsistencies and his shifting and sometimes
contradictory formulations.55
|
One major alternative
challenged the stress model during the height of its initial
popularity. George Engel and his colleagues at the University of
Rochester Medical Center developed a theory they ultimately called
"conservation-withdrawal." Like Selye, Engel and his associates
focused on psychobiological threats to an individual’s well-being.
But instead of considering threats as "stressors" that elicited
defensive and protective behaviors from the hyperaroused organism,
the Rochester group conceptualized the most important of these
behaviors in terms of "losses" and "deprivations" that caused the
organism to become withdrawn, depressed and shut-down.56
The Rochester group was generally attuned to psychoanalytic theory
and remained committed to preserving a place for it even in
psychosomatic medicine. They thus developed a complex scheme framed
in terms of disrupted relationships between individuals, affects of
"helplessness" and "hopelessness," and a state of
"conservation-withdrawal" in which physiological function was
depressed to the point of creating a "final common pathway" to
illness and death. |

Monitoring Monica
|
Monica's gastric (stomach) secretions, Engel and
his associates found that physiological activity increased sharply,
not only in the presence of food, but in the course of Monica's
interactions with other trusted human beings. Joyful reunions
following separation were associated with especially copious
secretions. At the same time, when Monica emotionally disengaged and
withdrew-- for example, in the presence of a stranger--there was a
pronounced shutdown of physiological activity. In a sense, the body
"withdrew" also, as if trying to conserve resources.
|
The Rochester group’s work
grew at the juncture between clinical studies on such diseases as
leukemia and ulcerative colitis57
and a naturalistic experiment on an infant, "Monica," who was
fortuitously admitted to Rochester’s Strong Memorial Hospital during
the course of their work.58
Monica had been born with a blockage in her esophagus, which
required that two surgical openings be made, one in her neck to
drain anything she took by mouth and one in her stomach through
which she could be fed. Monica did not do well and was admitted to
the hospital at fifteen months in a dangerous condition. While she
was being nursed back to health, Engel and his associates designed a
study in which they measured her gastric secretion continuously and
correlated their observations with Monica’s moods. They found that
Monica’s physiological activity increased when she was engaged with
the members of the group, whether joyfully or angrily, and
especially on reunion after separation. By contrast, her gastric
secretion ceased entirely, and even became unresponsive to histamine
(which normally stimulates gastric secretion), when she withdrew
physically and emotionally from a stranger who replaced the familiar
members of the group. Monica’s behavior made sense as a
psychological and physiological shutdown that served to conserve her
organismic resources. It also helped put into perspective the
separately collected clinical data on patients who articulated
feelings of "giving up" or being "given up" shortly before the onset
or exacerbation of a variety of somatic diseases.59
|
By the 1970s the
psychosomatic field thus had a pair of new concepts, one emphasizing
stress-induced hyperarousal and the other deprivation-caused
hypoarousal. A major achievement of the next decade was the merger
of this pair of ideas into one model of socio-environmental
challenge and response and the connection of that model with other
streams of work focused on "life change events" (divorce,
bereavement, and job loss) and "social stressors" (high intensity
living and work situations and major social dislocations from normal
support networks).60
The seventies were also notable for the application of progressively
more sophisticated biostatistical techniques and more rigorous
epidemiological study designs.61
Striking landmarks were Sidney Cobb and Robert M. Rose’s study of
"Hypertension, Peptic Ulcer, and Diabetes in Air Traffic
Controllers," the 1973 conference in New York City on "Stressful
Life Events," John Cassel’s Wade Hampton Frost Lecture of 1976 at
the American Public Health Association on "The Contribution of the
Social Environment to Host Resistance," and David Jenkins’s report
in the New England Journal of Medicine the same year of
substantial evidence confirming the significance of the "Type A"
behavior pattern as a risk factor for coronary artery disease.62
Although there were critics of some of this new work in
psychosomatic medicine, the strong consensus in the 1970s--both
within the psychosomatic field and more broadly in science and
medicine--was that studies on the relationship between social
support, life stress, and disease onset were significant and very
promising for the future.63
It was well established in the popular imagination that the stress
of modern life, work-related tension and anxiety, and devastating
tragedy accompanied by the loss of community could lead to very
severe health consequences. |
The chief and primary cause of ... [the] very rapid
increase of nervousness is modern civilization, which is
distinguished from the ancient by these five characteristics:
steampower, the periodical press, the telegraph, the sciences, and
the mental activity of women.

Saratoga
Spa, N.Y., ca. 1950s
|
A vacation "in the country," away from the routines
of life remains a tried-and-true remedy for "stress."
|
Also notable in the seventies
was the translation of new theoretical insights into practical
intervention strategies, sometimes actively promoted by the
researchers themselves. Thus, Meyer Friedman and Ray Rosenman, the
physicians who initially defined the Type A concept, published a
popular book which included practical chapters on how to
"reengineer" one’s daily life and develop "drills" to replace old
and harmful habits.64
Similarly, Harvard’s Herbert Benson promoted a simple, "noncultic"
technique to elicit the "relaxation response" as a counter to the
stress-induced "emergency response." He showed that physicians could
teach the relaxation response to patients as either a preventive or
therapeutic strategy. 65
Several other investigators introduced "biofeedback"
techniques (in which various physiological variables such as heart
rate and muscle tension were displayed to the patient) as practical
clinical methods for managing hypertension and a variety of other
conditions. 66

Volvo
Assembly Line , Sweden
|
|
In 1987 the Volvo Truck Corporation initiated a
significant effort to improve the environment of its factories and
alter the assembly process. Scientists documented blood pressure,
stress hormones and attitudes of workers before and after
restructuring the way car and truck engines were put together and
found that after the changes, perceived stress, blood pressure and
epinephrine levels of the employees decreased and morale increased.
|
In work settings, employers
introduced timeouts for stress-reducing exercise sessions and even
redesigned the production process itself. Of course, the
time-honored "vacation in the country" or "stay at the spa" remained
popular outlets for people’s accumulated tension. But in a period
sensitive to the importance of loss as well as overload, health
practitioners introduced newer interventions to affiliate isolated
and vulnerable people with one another through support groups, to
provide them with beloved objects of affection, and to encourage
shared group solidarity of great symbolic and emotional
significance.If stress and deprivation could cause disease,
relaxation and reconnection may be able to cure it or, at least,
mitigate its effects. |
