► 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!

Common symptoms in primary care (Mayou and Farmer, 2002)

► Precontemplation: not intending to make any changes

► Contemplation considering a change

► Preparation making small changes

► Action: actively engaging in a new behaviour

The transtheoretical model of behaviour change (Prochaska & DiClemente, 1982)

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)

Knowledge systems and health behaviour

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

Breast-cancer patients’illness attributions(Taylor, 1985)

► Illness representations

- interpret symptoms

- and give them meaning

►The course of action taken will be determined by the representation

Typical illness metaphors

► Challenge

► Enemy

► Loss

► Gain (primary / secondary)

► Punishment

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”
