Half a day to a full day
2
Q
What factors influence symptom recognition?
A
Individual difference/personality Cultural difference Situational factors Stress Mood
3
Q
How do individual differences effect symptom recognition?
A
Personality impacts your psychological disposition and therefore your health
Hypochondriacs and neuroticism automatically assume the worst case
People with depression and anxiety get sick more often but deny getting sick
4
Q
How do cultural differences affect symptom recognition?
A
Difference in emotional responses
Certain cultures talk about illness more than others
Ex. Asia does not talk about being sick and goes to work sick
Some look for symptoms while others ignore them
5
Q
What is medical students disease?
A
Learn about disease in med school
Students paying attention begin showing these symptoms
Changes every lecture and students believe they have begun expressing what they are learning
6
Q
What is an illness representation (schéma)?
A
A patients own implicit common sense belief about their illnesses
Begins as soon as symptoms appear or you get diagnosed
What you know about the disease and its symptoms
7
Q
What are the five distinct components of illness schémas?
A
Identify(label) Consequences Causes Duration Cure Well defined schémas are less stressful as they have these five components
8
Q
What occurs as you go higher up in the medical chain?
A
Less likely to have an answer
9
Q
What are the three models of illness?
A
Acute: bacterial or viral, short duration
Chronic: multi-factorial, long duration
Cyclic: alternating periods of activity
10
Q
What other factors can influence the interpretation of symptoms?
A
Lay referral network: input from friends, family, and peers
Internet: background info, lifestyle modification
11
Q
How does age influence the use of health services?
A
Infants and the elderly are more likely to use health services that those in late adulthood
12
Q
How does gender influence the use of health services?
A
Women tend to seek help more because they have kids and are more proactive about their health
13
Q

Those who have more money tend to use the system less but see specialists more
Those who have less money are more likely to express illness more and seek general care
14
Q
How does culture influence the use of health services?
A
Visible minorities more commonly visit a physician
The language barrier is sometimes a déférant for visiting health services
Minorities seek fewer visits to specialists
Perceived quality of care
15
Q
How does social psychological influence the use of health services?
A
Your beliefs about the system effects your level of care
Individuals attitudes and beliefs about symptoms and health care
Health belief model states predictors include: perceived threat to health and belief of efficacy of interventions
16
Q
Why might a person seek the use of health services for emotional disturbances?
A
Individuals report physical symptoms which are triggered by psychological drivers
- university disease
- inappropriate assessment by physician
- limited access to psychologists
17
Q
What are worried we’ll individuals?

18
Q
What are somaticizers?
A
Individuals who express symptoms after personal emotional insult
Get dumped and feel terrible so go to the doctor for these symptoms, display physical symptoms with an emotional root
19
Q
Why do people deny their symptoms having a psychological root?
A
Medical disorders are perceived as more legitimate than psychological disorders
Allowed more access to benefits and secondary gains
Tests occur faster if medical based
20
Q
What are secondary gains?
A
Downstream benefits arising from the illness
- time off/rest
- removal of responsibility
- medical symptoms vs psychological symptoms
21
Q
What is delay behaviour?
A
Patients live with one or more potentially serious symptoms without proper care
Delay is defined as the time between recognition and treatment

C fibers: unmyelinated fibers, secondary silk or aching pain, affects motivation and affective elements of pain, opens gate
A beta fibre: large, myelinated, information about vibration and position, concurrent stimulation can suppress pain from c fibres, closes gate
46
What is the traditional model of pain?
Pain resumed from transmission of pain signals to the brain
| Degree of pain was dictated by tissue damage
47
What is the gate control theory of pain?
Proposed that psychological factors contributed to pain experience
Neural pain gate can open/close to modulate pain signals to the brain
Fibres as well as physical, emotional, or cognitive factors open and close gate
48
What open and close the pain gate for the three different factors?
Physical: extent and inappropriate activity level open, medication and counter stimulation close
Emotional: anxiety, worry, tension, depression open, positive emotions, relaxation close
Cognitive: focus on pain/boredom opens, distension or life activities close
49
