Somatoform Disorders
An Outline: Psy 530
Carolyn R. Fallahi, Ph. D.
Somatoform disorders: persons who are overly preoccupied with their health or body. All of these disorders share one thing in common = no identifiable medical condition causing the physical complaints.
Hypochondriasis: physical complaints without a clear cause; anxiety focused on the possibility of having a serious disease.
· Shares many features with panic disorder
· Essential problem anxiety, but the expression is different from anxiety disorders
· Reassurance from a medical professional not lasting
· Differs in many ways from illness phobia
· Prevalence estimates
DSM-IV common features of Somatoform Disorders
· Presence of physical symptoms that suggest a general medical condition
· Symptoms not fully explained by medical condition
· Not due to substances or other mental disorders
Somatoform Disorders can be clustered into 2 larger categories:
· Classical hysterical disorders – somatization disorder, CD, pain disorder
· Preoccupation disorders – hypochondriasis, BDD
Issues related to Somatoform Disorders
· No reliable information about prevalence rates
· Lobo et al (1996) 9.4% of a large primary care sample = somatizers
· Low base rate in the general population
· Ethnicity understudied; Farooq et al (1995) Asian patients
· Etiology: onset & risk factors obscure; systematic knowledge lacking
· Preliminary thoughts: parental rearing, childhood development, stressful life events, personality, and communication & relationship with professionals
Research Studies:
· Torgerson (1986) genetic twin study – transmission environmental, esp sexual abuse.
Somatization Disorder
· Multiple physical complaints without clear/known physical causes
· Condition can last years
· 4 pain symptoms (back, abdomen, joints)
· 2 gastrointestinal symptoms (diarrhea, food intolerance)
· 1 sexual symptom (irregular menses, indifference to sexual activity)
· 1 pseudoneurological symptom (poor balance, numbness, paralysis)
· before the age of 30
· frequent and multiple medical consultations
· alters the person’s lifestyle
· full-blown somatization disorder rare - .2% men; .2 to 2.0% women; lifetime 0.1% in general population.
· Historical explanations: ancient Greeks – wandering uterus; 19th C Briquet polysymptomatic somatic condition = Briquet’s syndrome; Guze & Perley (1963) “somatization disorder”.
· Contemporary Thoughts: small subset of patients; functional symptoms; what happens?
· Somatosensory amplification
· Maintenance of the disorder
· Prognosis
Conversion Disorder
· Symptoms look neurological, e.g. glove anesthesia.
· 4 subtypes: motor symptoms or deficits; seizures or convulsions; sensory symptoms or deficits; mixed presentation
· important requirement: temporal relation between symptoms & psychological stressor.
· Distress or la belle indifference
· Prevalence unknown, but estimates .001 and .3% population.
· Historical explanations: “neuroses”; Charcot & hysterical conversions under hypnosis; defense mechanisms; Freud’s explanation.
· Contemporary Theories: Ullman & Krasner (1975) learned via behaviorism; Folks, Ford, & Regan (1984) sociocultural influences; Kellner (1991) neurophysiological studies show patients with CD do not habituate in the same ways as other patients; the role of emotional arousal.
· Onset late childhood or early adulthood.
· Grief & sexual trauma often involved.
· Mace & Trimble (1996) 10 year follow-up.
Pain Disorder
· Severe acute or chronic pain in one or more body parts is not entirely or adequately explained by a known medical condition
· Psychological factors involved.
· Acute versus chronic
· Prevalence unknown – relatively common
· Historical explanations: Aristotle; Descartes; Epicetus; Religious leaders; unidimensionality of pain.
· After 20th C, integrated explanations that were organic & psychological.
· Fordyce (1976) behaviorist explanations
· Cognitive-behavioral explanations.
· High frequency trauma & personality disturbance.
· Engle (1959) pain-prone personality
· Occupational factors important
Hypochondriasis: unjustified fears or convictions that one has a serious/fatal illness.
· 6 months & not of delusional intensity
· 3 to 14% medical patients (Kenyon, 1976); 16% general population illness phobia (Agras et al, 1969); 10% general practice (Palson, 1988); patients with increased exposure to medical settings
· Historical explanations: “Below the cartilage” – excess of black bile; 17thC Thomas Sydenham = equivalent to hysteria; Freud
· Contemporary Theories: behavioral theories; learned disorder; cognitive explanations; somatosensory amplification.
· Chronic condition.
· Children’s symptoms versus adult’s symptoms.
· Sexual trauma
Body Dysmorphic Disorder
· Preoccupation with an imagined or exaggerated body disfigurement/excessive concern that there is something wrong with the shape/appearance of body parts.
· Examples.
· Cognitive features.
· Typical behaviors.
· Prevalence unknown, but…. Rosen (1995) & Connolly & Gipson (1978)
· Not equal to unhappiness about one’s appearance.
· Historical explanations: 19th C Enrico Morselli – sudden onset & persistence of an idea that the body is deformed with severe anxiety. Morselli – obsessive nature. Recent views = no to phobic anxiety.
· Core problem: perception of abnormality.
· Contemporary theories: Rosen (1995) cognitive-behavioral explanation.
· Gradual / sudden onset; course continuous & chronic.
· Only anecdotal evidence.
· Beings in adolescence.
· Sociocultural factors. Perfectioinstic features.
Factitious Disorder
· Physical symptoms produced or feigned intentionally to assume the sick role.
· Eager to undergo extensive medical procedures.
· Pathological compulsion to deceive medical professionals = pseudologia phantastica.
· Different from malingering.
· Munchhausen Syndrome; munchhausen-by-proxy.
· Historical explanation: Munchhausen syndrome coined by Asher (1951) to describe patients who sought hospitalization at different hospitals under often dramatic circumstances for self-induced or simulated illnesses.
· Etiology not well understood, many authors feel it is the patient’s need for being taken care of.
· Trauma & abuse early in life.
· Early experiences with medical procedures & grudge against medical profession.
· Onset adulthood & chronic.
· Poor prognosis if patient goes from hospital to hospital.
· Severe personality disorders associated with this diagnosis.
