Linking Emotions with Physical Symptoms
“The good physician treats the disease, but
the great physician treats the person.”
William Osler
Non-Specific Symptoms
Often missed in assessment
Dualism
“If you are distressed by anything external, the pain is not due to the thing
itself, but to your estimate of it; this you have the power to revoke at any
moment”
Marcus Aurelius 180BC
Dualism
Mind / Body Divide

Common Chronic Ill-Health Complaints
• Low Back Pain
• Carpal Tunnel Syndrome
• Cumulative Trauma Disorders
• Tendonytis
• Repetitive Strain Injury
• Fibromyalgia
• Irritable Bowel Syndrome
• Chronic Fatigue
FORMS OF
CHRONIC PAIN
& FATIGUE
Those with heightened symptoms choose attributions to match concepts of
what is currently acceptable in medicine
External cause for illness preferred - patient becomes a helpless victim
Chronic Patient’s Attributions of Ill-Health
• Work
• Environment
Chemicals
Stress
Toxins
Virus
Allergies
• Traumatic injury
• Anatomy / Ergonomic
Common Misconceptions about Health
“I like
money”
“I like
money too”
“Exploit someone new today”
Allergies – the role of psychology
Allergies
Somatization and Fashionable Diagnoses
Somatoform Disorders (DSM IV category) “Somatization disorder”
Psychiatric diagnosis
Somatization
1. Rationalisation for psychosocial problems
2. Coping mechanism
3. Becomes a way of life
Fibromyalgia
Multiple Chemical Sensitivity
Dysautonomia
Reactive Hypoglycemia
Irritable Bowel Syndrome
Chronic Fatigue Syndrome

Vague subjective multisystem complaints
Lack of objective lab findings e.g no organic cause
Semi-scientific explanations e.g “post-viral syndrome”
Symptoms consistent with Depression, Anxiety or general unhappiness

Psychological / Perceptual Process of Illness
Internal Processes
“Do
I notice internal changes?”
“Should

I interpret them negatively?”
“Should I think they are important?”
External processes

“Do I notice external sources?”

“What should I believe about it?”

“What should I do about it?”
MENTAL SCHEMA
Internal representation of the world
(knowledge, attitudes, beliefs)
What do we believe about health?
What do we believe affects health?
Factors Influencing Symptom Development
Selective Internal Attention
Tedious & un-stimulating environment
Little communication
Stressful environment
Learned behaviours
“Negative Affectivity”
OVER FOCUS ON SYMPTOMS
Comparisons
Attributions
Responses
Blame
Pessimism
Factors Influencing Symptom Development
Selective External Attention


Heightened concern about risk
involuntary
uncontrolled
lack of information
dreaded consequences
Mistrust of government / industry
 Attitudes about medicine

Political agenda

Legal agenda

Social and political climate

Psychology important in how symptoms are perceived and reacted to
Chronic Fatigue Syndrome
• Non-specific subjective symptom
• Overlap with psychiatric diagnoses (66%)
• Chronic long-term inability and tiredness
• Both Physical and Psychological fatigue
• Most prevalent in white, middle class thirtysomething females
• Fatigue dominates activities and life
Bias – The placebo effect really does work!
Most effective medication known!
In approx. 30% of pop.
Subjected to more clinical trials than any other medicament
Nearly always does better than anticipated
The range of susceptible conditions seems limitless
Does not always occur
Present in subjective and objective outcomes
Negative outcomes can occur (Nocebo effect)
•Big pills better than smaller pills
•Red pills better than blue
Patient’s “knowledge” of their treatment causes bias
•4 pills better than 2
e.g. Benedetti & the Turin study
•30% of pop.
•Sham surgery vs arthroscopy for osteoarthritis
Treatment Bias of Healthcare

Hierarchy of Needs

NEEDS
Esteem (self and others)
Belonging (group membership, affection, companionship)

Security (safety, stability, continuity)
Bodily needs (food, drink, safety)

Four Pathways of Psychological Factors in Ill-Health
1)
Part of Cause of Health Condition
e.g.
Influencing factors (personality)
Risky behaviours
2)
Part of Health Condition
e.g.
Stroke, Metastases
3)
Effects of Health Condition
e.g.
Chronic ill-health
4)
Psychological Interventions
e.g.
Therapeutic benefits
Increased compliance
depression, anxiety, withdrawal
Compensation Neurosis
Pending litigation
Treatment results often poor
Some overt malingering
Exaggerated illness due to:
suggestion
+
somatization
rationalization +
distorted sense of justice
victim status
+
entitlement
Adverse legal / admin. systems
Harden patient’s convictions
With time, care-eliciting behaviour may remain permanent
Bellamy, 1997
Compensation Neurosis
Improvement in health.....
...may result in loss of status
Patient compelled to guard against getting better
Financial reward for illness is a powerful nocebo
Exacerbates illness
In a litigious society, will compensation neurosis become more widespread?
Accident Neurosis
• Failure to improve with treatment until compensation issue settled
• Accident must occur in circumstances with potential for compensation
payment
• Inverse relationship to severity of injury - Accident neurosis rare in cases of
severe injury
• Low socio-economic status favors accident neurosis
• Complete recovery common following settlement of compensation issue

Wharfie’s back
Mendelson, 1984
Secondary Gain Pre-disposition
What is the Motivation?
• Desire for attention
• Punish spouse / others
• Solve life’s problems
• Cry for help
• Diversion from work
• Socially approved task avoidance
sex with spouse
work
military duty
Secondary Gain Pre-disposition
Non-economic motivation?

• Difficulty expressing emotional pain
• Previous history of attention seeking when ill
• Depression
• Anxiety
Secondary Gain Pre-disposition
Who are the Potential Claimants?
• Military patients nearing severance
• Workers under retirement age
• Low job satisfaction
• Workers soon to be made redundant
• Members of support groups
Abnormal Illness Behaviour (Care Eliciting Behaviour)
• Disability disproportionate to detectable illness
• Constant search for disease validation
• Relentless pursuit of “enlightened doctors”
• Appeals to doctor’s responsibility
• Attitude of personal vulnerability and entitlement to care by others
• Avoidance of health roles due to lack of skills and fear of failure
• Adoption of sick role due to rewards from family, friends, physicians
• Behaviours which sustain the sick role - complaints, demands, threats
Blackwell, 1987

Conclusion
• Somatization influenced by numerous factors
• Sick role resolves intrapsychic, interpersonal or social problems
• Fashionable diagnoses have considerable overlap
• Occupational and Environmental syndromes
• Non specific and subjective complaints
• Underlying depression, anxiety, and history of unexplained complaints
• Mass communication + support groups = fashionable way to solve distress
• Behavioural aspects of chronic patients – blame, refusal, over-reporting etc.
