Medical Psychology Patients’ Representations and Beliefs about Illness
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!
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 ► Maintenance sustaining change over time The transtheoretical model of behaviour change (Prochaska & DiClemente, 1982)

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
I llness Cognitions (Leventhal & Nerenz, 1985) 1. Identity Diagnosis ( a cold ) and symptoms ( runny nose, fever ) 2. Perceived cause of illness Stress, a virus, unhealthy lifestyle 3. Time line Acute or chronic 4. 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 Perception Questionnaire (Moss& Morris, 2002) Timeline: acute/chronic – My illness is likely to be permanent rather than temporary Timeline: cyclical – My symptoms come and go in cycles Consequences – My illness has major consequences on my life Personal control – What I do can determine whether my illness gets better or worse Treatment control – My treatment can control my illness Illness coherence – I have a clear picture or understanding of my condition Emotional representations – When I think about my illness I get upset
