27
how does the Bio-Psycho-Social model link to definition of health in the 20th century?
- 3 major killers= heart disease, cancer, vascular disease
| - proven to directly link with psycho-social factors (smoking, stress, diet and exercise)
28
who uses health services and why?
- children (developing immune systems)
- elderly people (failing immune systems)
- women (pregnancy and childbirth)
- men (most likely to ignore symptoms)
29
how does attention affect the recognition of health?
- INTERNALLY FOCUSED people=focus on themselves so more likely to notice & report illness
- EXTERNALLY FOCUSED people=focus on environment so may not report illnesses
30
what are Sensitizers/monitors?
people who seek out information about their lillness
31

35
what is UTILISATION delay?
time between deciding to seek advice and actually seeking it
36
what is SCHEDULING delay?
time between making appointment and receiving treatment
37
what is a malingering?
- believing you are ill and remaining ill for secondary rewards
- form of overusing the health service
38
what are the reasons for malingering?
- emotional rewards:increased attention
| - practical rewards:access to controlled medication/free from responsibility/financial gain
39
what emotional problems cause overusing of the heath service?
stress can cause high BP which is often mistaken for an illness
40
what factors help us to visit a practitioner?
1. persistence of symptoms
2. critical incident (sudden change in symptoms)
3. treatment expectations (believing that the GP can make a difference
41
two types of consultations
- doctor centered
| - patient centered
42
doctor centered consultation
- doctor is dominant->doctor makes decisions->patient is passive
- used in serious/terminal illnesses
- maximizes chances of being correct
43
patient centered consultation
- patient is active->joint decision between doctor and patient->doctor actively listens
- used in less serious illnesses
44
what factors can influence the success of a consultation?
-physical=appearance of the doctor, eye contact, tone of voice, gestures, gender, age
situational= items in the office, how busy the doctor appears to be
45
factors that affect making a successful diagnosis
1. primacy effect-.importance placed on what physician heard first
2. knowledge of the patient-frequency could mean a known malingerer
3. self-report-absence of obvious signs, physician must rely on what patient said
46
effect of computers in health diagnosis
people may not seek medical advice for embarrassing symptoms
47
what is compliance?
- how well patient's behaviour matches treatment plan set up BY DOCTOR
- DOCTOR CENTRED and patient is passive
48
what is adherence?
- how well the patient's behaviour matches the treatment plan they AGREE with the doctor
- PATIENT CENTRED (joint effort)
49
what is concordance?
-RECIPROCAL ALLIANCE between patient and doctor
50
what affects medical non-adherence?
-severity of illness (60%of terminally ill patients don't take medication due to fatalistic beliefs OR mild illnesses)
51
what are medical non-adherence behaviours?
- not taking pills
- skipping doses
- altering the medical plan
- not adhering to eating, drinking/resting guidelines
52
methods of measuring non-adherence? (6 points)
1. self report (ask the patient)
2. therapeutic outcome (patient getting better)
3. doctor estimates their health
4. pill and bottle counts
5. electronic methods (data recorded in pill bottles)
6. biochemical tests
53
limitation of self-report techniques to measure non-adherence
patients may not be truthful
54
limitation of 'therapeutic outcome' to measure non-adherence
even non-adherers get better
55
limitation of 'doctors estimates' as a measure of non-adherence
doctors may predict wrongly
| have predicted non-adherence wrongly 41% of the time
56
limitation of 'pill/bottle counts' as a measure of non-adherence
pills may not have been consumed
57
limitation of 'recording data in pill bottles' as a measure of non-adherence
expensive
58
limitation of 'biochemical tests' as a measure of non-adherence
time consuming and confounding variables may affect results
59
three types of non-adherence

2. patients may remember information better when there are pictograms (images)
3. using simple and straightforward language
62
what are other factors that may affect non-adherence?
- depression: being de-motivated
| - this may be improved by a good support system of friends and family
63
what are the implications of medical non-adherence?
- increase in healthcare costs
64
describe research into non-adherence in patients with foot-ulcers
1. patients were told to elevate their feet, given antibiotics and special footwear
2. patients didn't adhere because FOOTWEAR WAS UNFASHIONABLE and FOOT-REST WAS BORING
3. they knew of the outcomes of not adhering
65
why do we experience pain?
it is 'adaptive'
| provides us with feedback about bodily systems which leads us to seek treatment
66
two types of pain
```
ACUTE pain (less than 6 months)
CHRONIC pain (more than 6 months)
```
67
what is acute pain?
- instant
- can be recurrent
- i.e migraines
68
what is chronic pain? (2types!)
1. Chronic BENIGN pain=long term experienced to a similar intensity
2. Chronic PROGRESSIVE pain=long term pain that worsens with time
69
ways of describing pain
- severity (mild, discomforting?)
- type (shooting, piercing?)
- pattern (continuous?)
70
how could we measure pain? (name of questionnaire and 4 domains)
McGill Pain Questionnaire:
1. Sensory-how it feels
2. Affective-how it affects emotionally
3. Evaluative-pain intensity
4. Miscellaneous
71
what is a disadvantage of the McGill Pain Questionnaire of measuring pain?
- designed by doctors so level of high level of literacy required
- time consuming
- open to biases (self-report)
72
name two examples of objective measures of pain in the lab
1. COLD PRESSOR TASK: 'can you feel the pain'
| 2. ALGOMETER: facial expressions/BP and HR measures
73
biological theories of pain
- Specificity Theory
| - Pattern theory
74
what is the Specificity theory of pain (biological)
pain RECEPTORS in the skin detect pain related information via neurons and SENDS INFO to the brain
75
what is the pattern theory of pain (biological)
pain RECEPTORS send pain related information to the brain via NERVE IMPULSES but neural stimulation must reach a CRITCAL VALUE for pain sensations to occur
76
What are the limitations of biological theories of pain?
- doesn't explain PAIN BUT NO RECEPTORS (Phantom Limb Syndrome)
- doesn't explain RECEPTORS BUT NO PAIN (congenital analgesia; born with receptors but don't feel pain)
77
What is neural plasticity?
receptors in one part of the brain are dormant so receptors in anther part try to compensate by creating sensations in the other part
78
what psychological factors affect detection of pain?
-LACK OF ATTENTION:
doesn't perceive pain immediately; often in sport
-DISTRACTIONS
-PAIN MEANINGTHEY COULD GO HOME (occurred in soldiers)
-DEPRESSION resulted in higher pain perception
79
describe the Bio-Psycho-Social model of explaining pain (Gate Control Theory)
- Pain Gate exists in the SPINAL COLUMN which opens and closes to allow pain messages through
- NEGATIVE EMOTIONS=OPEN GATE MORE/POSITIVE EMOTIONS=CLOSE GATE MORE
80
What are some advantages of the Gate Control Theory explanation of pain?
1. integrates psychological factors
2. allows for variability of pain perception
3. psychological interventions to treat pain; positive emotions=close gate
81
biological pain treatments
1. drugs i.e morphine(negative=side effects; addiction)
| 2. biofeedback-tracking HR and BP then changing lifestyle
82
psychological treatments of pain
1. hypnosis/relaxation
| 2. distration techniques
83
defining stress
1. what causes stress (weather/financial worries)
| 2. the response we get from stress (anxiety/HR and BP)
84
classic model of stress: FIGHTOR FLIGHT
- activation of the Sympathetic Nervous System
| - illicit physiological responses to deal with stress (HR)
85
classic model of stress: GENERAL ADAPTATION SYNDROME (GAS model)
-suggests people react similarly to stress
HOWEVER
-there are individual differences in responses to stress
86
Transactional Model of Stress
- idea that when a person is THREATENED and LACK RESOURCES to cope=stress
- explains why same stressors cause different responses
87
what is 'habituation' in stress?
coping with the same stressor when repeatedly presented
88
what is Psycho-Neuro-Immunology in stress?
the link between psychological factors (e.g. stress) and disease, via interactions between the nervous, endocrine and immune systems
89
describe stress response following the SAM Axis
1. detect stressor
2. negative emotional response
3. Sympathetic Nerves
4. Adrenal Medulla
5. Excrete Adrenaline/Noradrenaline
(immediate)
90
describe stress response following the HPA Axis
1. detect stressor
2. Hypothalamus
3. Pituitary gland
4. adrenal cortex
5. release cortisol
(takes longer than 20 mins)
91
why does the stress response become maladaptive
-modern stressors are financial/psychological and hardly stop
SO
-body continuously releases adrenaline/noradrenaline causing high blood pressure
92
methods of measuring stress (psychological)
1. reports of negative and positive emotions
| 2. questionnaires
93
method of measuring stress (physiological)
1. Adrenaline/Noradrenaline levels (HR, BP)
| 2. Cortisol levels (hair, saliva)
94
measuring the effects of NATURALISTIC stressors
- measuring cortisol levels and showing in a Diurnal Cortisol Pattern
- could result in CARDIOVASCULAR DISEASES, BUROUT, MEABOLIC SYNDROMES
95
measuring the effects of CONTROLLED LAB stressors
- public speaking
- Stroop task
- mental arithmetic
- noise manipulation
- mirror tracing tasks
96
what is a disadvantage of Controlled lab studies?
-not representative of real life stress
97
describe social support as a method of coping with stress
Philips 2006
-presence of a spouse/partner reduced BP in a lab based stress task (in women)
Lovell 2012
-support for caregivers improved psychological health
98
describe personality factors as a method of coping with stress
Kobasa 1979
'Hardiness' =more adaptive psycho-physiological responses to stress (high hardiness=less health complaints)
2. Type A personality=more health problems
99
Describe factors of Hardiness by Kobasa, 1979 as a way of dealing with stress
- Commitment=having a sense of purpose in life
- Control=belief that we can influence events in our life (high LOC)
- Challenge=perceiving stress as a challenge (opportunity for growth)
100
describe the Type A personality in relations to coping with stress
- usually hostile, angry, self-critical, intolerant
- associated with increased vulnerability to stress related diseases
- Friedmann and Rosenman, 1974, found type A personality had twice as many heart attacks
101
how do we link Type A personality to stress related diseases?
DIRECT MECHANISMS=high stress behaviours->activation of stress system=tough on cardiovascular system->CD
INDIRECT MECHANISMS=high stress behaviours->coping behaviours i.e. smoking->tough on cardiovascular system->CD
102
what are coping behaviours of stress?
- emotion focus (acute stress)=flight i.e. sleep, denial, distraction, substance use
- problem focused (chronic stress)=take action to deal with stress i.e. be proactive
- Animal Assisted Interaction is associated with improved cognition and immunity
103
describe virtual reality as a method of coping with stress
- high quality computer graphics and sounds to allow people face their stressors before going into the real world
- Advantages: time efficient, low cost, mobile, easy to use
- beneficial or children with autism, phobia, depressive patients
104
measuring obesity
BMI
-weight (kg) ÷ height (metres squared)
WEIGHT-HIP RATIO
-measures proportions of weight distribution around the torso
105
what are the BMI classifications of weight
```
less than 18.5=underweight
18.5-24.9=normal
25-29.9=overweight
more than 30=obese
more than 40=morbidly obese
```
106
what are some problems with BMI as a measure for obesity?
- doesn't differentiate between weight of muscle and fat
| - doesn't factor in bone density, natural habit end exercise
107
biological explanations for obesity
- adipocytes (fat cells)
| - basal metabolic rate
108
explain adipocytes as a biological explanation of obesity
- fat cells
- obese people have more, bigger adipocytes (due to genetics/childhood factors)
- energy input exceeds energy output=weight gain
109
explain BASAL METABOLIC RATE as a biological explanation of obesity
- levels of energy needed to sustain normal bodily functions
| - low BMR=metabolise fewer calories
110
explain genetics as a biological explanation of obesity
- high concordance rates for obesity (64-84%) for identical twins reared together
- research showed BMI of a twin reared in location A could predict BMI of second twin
111
explain Set-Point Theory as a biological explanation of obesity
- ideal biological weight=a set point
- if weight departs from the ideal, body induces or decreases food cravings
- determinist
112
explain hormone dysfunction as a biological explanation of obesity
- as body fat increases, so does LEPTIN to suppress the feelings of hunger (satiation)
- OB(Gene)=rats with this gene didn't produce enough leptin so body fat increases (cant stop eating)
113
explain socio-economic status as a psychological explanation of obesity
-lower SES=lower income, less education on diets/exercise, more stress = obesity
114
explain stress as a psychological explanation of obesity
stress increases eating behaviour
| Zellner, 2006, stressed participants picked calorie dense foods
115
explain cultural factors as a psychological explanation of obesity
-more adverts for unhealthy foods =high obesity rates
116
implications of obesity
- being able to determine health by body type
- Pears=healthy=weight is at the bottom part of the body=fat is far from major organs
- Apples=weight stored at the top of the body=may lead to coronary diseases (fat is close to major organs)
116

- being able to determine health by body type
- Pears=healthy=weight is at the bottom part of the body=fat is far from major organs
- Apples=weight stored at the top of the body=may lead to coronary diseases (fat is close to major organs)
117
what is substance misuse? (DSM-IV definition)
maladaptive pattern of substance use. leading to clinically significant impairment or distress:
1. need more amounts t achieve desired effect
2. withdrawal symptoms appear is not in use
3. unsuccessful efforts to cut down
4. reduce social/occupational activities
118
define substance misuse in short
a pattern of harmful use of any substance for mood-altering purposes
119
define substance misuse in short
a pattern of harmful use of any substance for mood-altering purposes
120
three categorises of substances

121
what are stimulants
- stimulates/excites neural activity
- examples: caffeine, nicotine, cocaine
- activates fight/flight
122
what are depressants
- depresses/inhibits neural activity
- sedatives, hypnotics, tranquilizers
- changes in mood, cognition

124
what are hallucinogens?
- alter sensory perception and induce visual and auditory hallucinations

125
mechanisms of drugs
agonists=enhance actions of neurotransmitters
| antagonists=inhibit actions of neurotransmitters
126
mechanisms of drugs
agonists=enhance actions of neurotransmitters
| antagonists=inhibit actions of neurotransmitters
127
Bio-Psycho-Social model of addiction
-repeated consumption of a substance with physical and psychological dependence
128
biological model of addiction
BRAIN REWARD PATHWAY (part of limbic system)
- rewards evolutionarily advantageous behaviours i.e. eating, drinking
- releases of dopamine which elicits, pleasurable feelings and causes repitition
129
psychological model of addiction
-imitation=doing what is seen
-classical conditioning=learn to associate drinking with social occasions so grow up doing so
operant conditioning=rewards of using drugs i.e positive mood, which causes repetition of behaviour
130
biological model of addiction
BRAIN REWARD PATHWAY (part of limbic system)
| -replaces and rewards the adaptive neural
131

-imitation=doing what is seen
-classical conditioning=learn to associate drinking with social occasions so grow up doing so
operant conditioning=rewards of using drugs i.e positive mood, which causes repetition of behaviour
132
psychological treatments of addictions
CBT:reinforcement: rewards for not taking substance
ABSTINENCE: eliminating dependence on substance
133
biological treatments of addictions
medication: inhibiting dopamine release=inhibiting dopamine release
134
psychological treatments of addictions
CBT
| -reinforcement: rewards for not taking substance
135
biologicaltreatments of addicitons
medication: inhibiting dopamine release=inhibiting dopamine release
136
relapse
more than 50% patients treated for alcohol addiction relapse within 3 months
