Transcript of Quick test question: What are the main psychological components of the biopsychosocial model?
High Prevalence of Somatic Symptoms
► 80-90% general population: > 1 symptom per week
► Typical adult: 1 symptom every 5-7 days
► 81% college students report > 1 symptom within 3 days
► 20% adults: “substantial,” “prolonged” fatigue
► 15%-30% back pain, joint pain, muscle pain within 2 weeks
► Only small minority seeks medical help!
► Precontemplation: not intending to make any changes
► Contemplation considering a change
► Preparation making small changes
► Action: actively engaging in a new behaviour
► Maintenance sustaining change over time
The transtheoretical model of behaviour change (Prochaska & DiClemente, 1982)
World Health Organization’s Definition of Health

Cultural Concepts of Health

• Harmony of mind, body, and spirit
► Asia:
• Physical and spiritual harmony with nature
• Balance of yin and yang
► Middle East:
• Spiritual Causes
• Cleanliness
► Western countries:

with diet, rest, exercise,
and prevention
Protective Objects:
• Amulets
• Bangles
• Talismans
Protective Substances:
• Garlic

Health care professionals must change to accommodate other cultural beliefs and behaviors towards health and illness
Lay Definitions for Health
A sample of 9000 British adults defined health as:
► not-ill: the absence of physical symptoms.► despite disease.► reserve: the presence of personal resources.► behaviour: the extent of healthy behaviour ► physical fitness► social relationships► vitality► function
(Blaxter, 1990)
Health-behaviour is related to the way in which people interpret their symptoms
Is behaviour that rational?
We have to take in consideration:
► Role of emotional factors such as fear and denial. ► The person’s belief in their ability to carry out behaviour ► How attitudes might change
► The measurement of each component
Illness Representations
► Illness representations will determine how someone responds to potential health threats
► Illness representations include:
Informations and beliefs about the illness
Illness Cognitions (Leventhal & Nerenz, 1985)
1. Identity• Diagnosis (a cold) and symptoms (runny nose, fever)2. Perceived cause of illness• Stress, a virus, unhealthy lifestyle3. Time line• Acute or chronic4. Consequences• Physical (pain, mobility problems) and emotional (lack of
social contact, anxiety)5. Cure & control• E.g. by taking medication or getting plenty of rest
► Illness representations
- interpret symptoms
- and give them meaning
►The course of action taken will be determined by the representation
Illness behaviour:is influenced by the individual’s interpretations of an
appropriate response to symptoms
pre-existing belief systems determined culturally &
experientially
dialogue with others & societal norms & values
May be initiated by one person on behalf of another – the
“lay referral system”
