Health psychology Flashcards
BIOLOGICAL STRESS SYSTEMS.
What is the parasympathetic system used for
Quick response, happens automatically, used to conserve energy for the fight or flight response. Does things like dilating pupils, speeding heart rate, slowing digestion.
What is the parasympathetic system used for
Countering and trying to get back to homeostasis, also happens automatically. does things like speeds digestion, stimulates saliva flow, slows heart rate
What happens in the SAM response
Stress activates the sympathetic nervous system
Which activates the adrenal medulla
Which releases adrenaline and noradrenaline
Which does things like speed up perspiration and respiration.
How does the HPAC response go
Stress activates the hypothalamus,
Which activates the pitutary gland
Which activates the adreno cortex
Which releases corticosteroids such as cortisol
Which does thing like increase energy, suppresses the immune and the inflammatory response
What is the main difference between the SAM and the HPAC
The sam is electrical response which uses nerves to happen quickly, and is over pretty quickly too. The HPAC is a wet system that is to do with actual hormones in the blood. It takes longer and lasts longer, cortisol in the blood long after the stressor is over.
What is one biological model of stress. And who suggested it?
Walter Cannon- said that the SAM is used for immediate threats. The fight of flight response. Evolution- we needed it to run away from predators etc
What does Selye’s say about the biological models of stress?
Claims that the HPAC response is experienced in the exact same way, no matter what the stressor is. this is the problem when it comes to the link between stress and illness. The HPAC is a more adaptive system which reacts to learned threats. Which are threatening in a symbolic way
What is the endocrine system
Linked to the HPAC, made up of ductless glands which transport hormones. Regulated by hypothalamus and pituitary gland
What is Selyes general adaptation syndrome
1) Stress activates the hypothalamus, which releases corticotrophin releasing factor.
2) Which activates the pituitary gland, which releases ACTH.
3) Which activates the adrenal cortex, which releases corticosteroids.
4) This acts on the hypothalamus to stop it releasing ACTH. Thus you become resistant to stress
Criticisms of Selye’s and Cannon
- only take into account the physiological effects to stress, not the importance of psychological.
- only looks at what happens after stress is experienced, not in anticipated stress
- not all stress responses are this uniform, affected by gender, personality, biology
How does stress effect the immune system.
Acute stress causes certain types of cells to prepare to fight illness or injury. Pro-inflammatory cytokines are released and have positive effects. After a while, this becomes prolonged and they can cause tissue damage and risk of disease
Two steps to how stress and immune system create a dangerous pattern
1) Stress causes the immune system to become disregulated
2) Disregulated immune system changes the way our bodies experience stress
What else can stress do to the body?
Shorten telomeres.
What are telomeres
They are the caps on our chromosomes which protect our DNA
How does stress shorten them
Telomeres are responsible for protecting our dna integrity, if they are shorter, the cells can’t be replicated as well as the integrity is damaged so it creates effects like ageing!
What did ‘rhymes with worry, sounds like mummy’ paper offer regarding the physiological effects of stress
‘rhymes with worry, sounds like mummy’ Those who experience stress early have an exaggerated immune response to stress. Poverty, abuse has long and short term effects on the immune system.
What did they find when looking at children who had been abused
Children have low levels of cytokines (which control the immune response). When immune cells are tested in vitro, abused children released more inflammatory cytokines, which are harmful to the immune response over time.
PSYCHOLOGICAL MODELS OF STRESS.
What is stress defined as?
A negative emotional experience accompanied by predictable changes that can be either biochemical, cognitive, behavioural or physiological.
What is the Tend and Befriend and who made it up ‘best friend squad’
Taylor 2006- found that women experience stress differently to men. They have more oxytocin in their blood and are more likely to reach out for support than to go into fight or flight mode, it down-regulates it. We have adapted to care for our offspring
Critical point to do with this
Not all women have high and not all men have low. Not so clean cut
What sort of behaviours are demonstrated in the tend and befriend
Affiliative behaviours
What happens when your affiliative behaviours are reected
Then oxytocin has been shown to actually exasperate the stress response
Two general findings that support the tend and befriend
- Animals with more oxytocin are calmed, more social and paternal/maternal.
- Under stress, women are more likely than men to reach out.
‘cardio-I swear I am SOOO not bothered!’
Cardioso et al., 2013- double blind experiment where ppts were given a social rejection paradigm (someone says they wouldn’t want to work with you) and then administered oxytocin or weren’t. Results showed that IF you reported negative mood after the paradigm and given ocytocin, you reported higher trust. But if you weren’t negatively affected by the paradigm them it made no difference. Shows it works on stress specifically
How does Taylor say the effects of oxytocin can be seen in real life?
Babies crying is a display of affiliation behaviours. The system they used it dependent on oxytocin.
Second example?
Women who reported relationship distress had higher levels of oxytocin. Those with high levels also more likely to describe their partners as unsupportive etc
How is stress defined in the cognitive transactional model?
Stress is a relationship between person and environment, in which that person has appraised as being taxing or exceeding their resources and endangering their well-being
‘4, hore, situation with laz didnt get me good appraisal’
Lazaurs and Folkman- 1984. Stress is in the eye of the beholder
Describe the cognitive transactional model
1) Primary Appraisal- first evaluation of the situation.
2) Secondary appraisal- evaluation of ability to cope
3) Reappraisal- continue to adapt or modify negative emotions using new information
What is the difference between prim and second
Secondary is where the coping strategies come into play. During primary, the event has happened. You’re looking back at it. Past oriented. Secondary is future oriented, you are looking forward.
RECAP- what are the 3 biological reactions to stress
1- confrontative action (fight)
2- withdrawal from threat (flight)
3- seek support (tend and befriend)
Define coping
Process of managing the discrepancy between threat and the resources we have. It is an ongoing process of appraisal and reappraisal (not static)
What are the two types of coping efforts?
action-oriented or intra-psychic
Lazarus and Folkman study procedure-
Looked at student taking an exam in 3 periods and assess coping styles in each. Anticipatory stage, waiting stage and outcome stage.
What were the results
coping styles changed during period. went from problem based to emotion based because there is no point using problem based when you’ve already given up control (taken the exam)
Critical point of this study
they assessed stress based on solid things like support network, which can’t be used to assess changes in actual coping style
what are the 3 types of social support
emotional support, informational support and tangible/practical support
STUDYING STRESS
How is stress measured? 4 ways
Self-report, behavioural, physiological measures (heart rare, blood pressure), biochemical markers (cortisol, catecholamines)
‘co-operate and tell us your stress’
Cohen’s stress scale- 10-15 items, quick and easy but not objective although it does correlate with other measures! taps into cog transactional because it talks about how they FEEL. its not the stressor, its the reactions to the stressor.
‘homes, how much has changed in yours?’
Holmes-Rahe- scored people on ‘life change units’ in the past year and how stressful they’d rate it. score under 100- low stress. over 300- high stress. found that those with more life change units have more health issues. good because records objective and subjective measures
Problems with these scales
some events are stressful for some but others. things like divorce. outdated to say thats the worst thing ever. should be updated to include current things like terrorism, politics etc
Inducing disease; ‘you feel as cold as stone when you have a cold’ procedure:
Stone, 1992- gave 100 students the cold virus in a nasal spray, and had them record stressful events. those with more events, more likely to get colds
What did cohen conclude about stressors
the length is more important than the severity
lab experiments, what are the 3 paradigms used
record stressful event (ecological validity because you experience stressor as you recall, people may not be imagining equally stressful events though), do a stress paradigm (public speaking etc) and imagine a stressful event- leave open ended as otherwise they go into secondary appraisal
difference between chronic and acute stress
acute: single, non-recurring, activates SAM and the paraSAM. chronic- repeated, persistent- either goes on too long or is ruminated on too long. delays return to homeostasis and activates the HPAC
what are the consequences of acute stress?
colds, flu
what are the consequences of chronic stress?
dysregulation of the inflammatory response, causes risk of CVD, diabetes, Alzheimer’s.
why might not all things cause chronic stress to some?
stress is in the eye of the beholder !!!!
‘when dan ignores me he goes from being a(cute) to being a chronic asshole’ what was his suggestions?
Smyth, 2013- acute goes to chronic if:
1) you have a delayed return to homeostasis (its prolonged)
2) you have slow or no adaptation to the stressor (perceive it as a threat even when it is present)
3) the acute stressor is repeatedly activated
what else did smyth say about stress?
its not the stressor- its you! stressors being acute or chronic is a continuum not 2 set stages
definition of chronic stress with this in mind
‘the interplay between external and internal resources. its self-generated and contributes to continued appraisal’
‘persevere and you will finally get your shot!’ what did this guy say about chronic stress?
Brosschot, 2006- we have ‘perseverative cognitions’ which refers to repeated/chronic activation of the mental REPRESENTATOINS of the stressors!
how are we different to animals in the way that we experience stress?
animals will run away from a stressor and not think about it again, we ruminate on what could have been
‘mccullough from OITNB had stressful weeks and defo lots of cortisol at her job’ what did this study into the effects of rumination do?
McCullough, 2007- 125 undergraduate students had to self-report rumination, fear and anger and then measured their cortisol at baseline and after 2 weeks
what were mccullough’s results?
those who ruminate more, had higher cortisol levels
what did Brosschot say about rumination?
perseveration hypothesis- ruminating on many stressors has dire health consequences
‘flet, stop fretting over eveything!!!’ what did they define perfectionism as
Flet et al., 1998- frequent cognitions about the attainments of ideal standards
Flet et al., study?
found that perfectionism was associated with stress, worry and rumination
COPING AND SELF-COMPASSION.
‘Taylors squad’ what did they say about stress and coping?
our resources to fight stress can be internal, external or social. social support and coping style can diminish the relationship between stress and illness
what is the cycle of coping styles and stress
Coping styles modify how you view stress and how you view stress modifies how you EXPERIENCE it
two types of coping:
emotion based and problem based
what can they also be based in
avoidance or approach based
what happens with chronic/acute stress when avoidance is used
chronic and avoidance= higher stress. acute and avoidance= could be helpful at times
‘carver reminds me of christmas which is defo something i have to cope with lol’ how do we measure peoples coping styles?
carver 1997- the COPE scale. distinguishes between avoidance and acceptance based coping.
who coined and defined self compassion
Kristen Neff- 2003- kind and understanding towards oneself during times of pain or failure, rather than being harshly self-critical
what are the 3 components of self compassion
self kindness, common humanity, mindfulness
what are the opposites
self criticism, isolation and over-identification. all cause rumination and make a stressor chronic
what are the two types of self compassion
trait self compassion- constantly reacting to things in self compassionate ways. state- can be trained, reminded and learnt
research into self-compassion and self reported stress. ‘brienne the LGBT icon’
Brion- self compassionate HIV patients reported less anxiety, guilt and stress.
‘be kind to yourself and you won’t feel weary!’ general finding
Allen and Leary, 2010- self compassion is associated with lower self perceived stress
Neff and Garmer 2013 findings
self compassion interventions decrease self reported stress
‘women arch their back in yoga- a practice for self compassion, physical effects’ what did this study find about self compassion and objective measures of stress
Arch 2014- women were given a self-compassion training and then looked at physiological effects. results showed ones with the intervention had ore adaptive parasympathetic heart rate activity with better heart rate variability. and lower SAM reactivity (shown through saliva alpha amylate)
what are allen and leary’s 6 coping mechanisms?
- positive cognitive reframing
- avoidance and escape
- distraction
- proactive coping
- problem solving
- seeking support
Taylor et al., what else can help and why?
relaxation techniques like yoga- the biofeedback restores the parasympatheic nervous system because its aiming to reduce hyperarousal or curb emotional-physiological reactivity
‘B.A.R- they were all barking mad’ how do these people define mindfulness?
Brown and Ryan, 2003- systematic training in meditation to help people self-regulate their reaction to stress and any resulting negative emotions’
what is mindfulness based on
the idea of becoming more aware of the present moment and therefore less distracted by distressing thoughts and feelings that arise in response to a stressor.
what does mindfulness based stress reduction focus on?
learning to approach situations mindfully rather than automatically
‘students need to get in devibeeeee’ what did this study do to investigate mindfulness?
DeVibe- 288 students took a 7 week mindfulness course. they were testing to see if mental distress, study stress, burnout, subjective well-being and mindfulness improved. also did a 5 facet questionnaire which tested non-reacting, non-judging, act with awareness, observe and describe aspects to mindfulness
what were the results?
effects were only found in females and only for mental distress and subjective well being. and it only helped the non-reacting part
why do you think this was?
maybe mindfulness more accessible in women. those who engaged more and went to more sessions did better, maybe women are lower in self compassion and this is why you see the biggest effect
HEALTH PROMOTION
what is WHO’s definition of health promotion
the process of enabling people to increase control over, and to improve, health
through what can it happen
individual efforts, legislation, medical system, media
what are the 3 types of disease prevention
1) primary prevention- seatbelts, vaccines, avoiding in the first place
2) secondary prevention- catching it as quickly as poss, screenings
3) tertiary prevention- dealing with it properly post diagnosis- visiting specialist
diff between health behaviours and health habits
habits are automatic and engage without thinking. behaviours are modifiable risk factors that we do to maintain health
what 2 categories do health behaviours fall under?
wellness, health maintenance and enhancement and accident control
