Stress Flashcards
What is stress?
Stress is how our body reacts when we are feeling under pressure or threatened in some way.
Describe the physiology of stress.
- The General Adaptation Syndrome is a 3-stage process that describes the biological changes the body goes through when under any type of stress.
State the 3 stages of the GAS model.
- Alarm stage
- Resistance stage
- Exhaustion stage
Describe the alarm stage.
- Fight or flight response, where cortisol and adrenaline are released to give you increased energy.
- Heart rate increases and faster breathing to enable more oxygen.
Describe the resistance stage.
- Body starts to repair and recover after the initial shock of the stressor has passed.
- If the stressor is ongoing, your body remains on high alert and adapts to living in high stress conditions.
- Stress hormone will continue secretion and blood pressure will remain high.
Describe the exhaustion stage.
- Ice exposed to prolonged or chronic stress, this can drain you of emotional, mental and physical resources and your body wont be able to effectively fight the stress.
- Signs of exhaustion are fatigue, depression, anxiety and decreased tolerance for stress.
State some of the minor health problems from stress.
- Headaches
- Insomnia
- Changes in appetite
- Nausea
- Heartburn
State some of the major health problems from stress.
- Type 2 diabetes
- Alcohol or substance abuse
- High blood pressure
- Weakened immune system
What are the 3 sources of stress?
- Life events
- Work
- Personality
Explain life events as a source of stress.
- Proposed by Holmes and Rahe.
- Life events are any major change in your life and can be both positive and negative.
- The SRRS was given to 2,500 American males and results showed significant positive correlation between life change score and illness score.
What is the social readjustment rating scale.
- A scale inclusive of 43 life events.
- Each event is given a score and respondent must identify all events which they have experienced over the past year.
- The higher the total score, the more likely to develop a stress-related illness.
Explain work as a source of stress.
- There are many work aspects responsible for the cause of stress.
- Such as the physical environment, interpersonal relationships and the pressure of meeting targets.
- Coronary heart disease is one of the many stress-related illnesses.
Explain the Whitehall study by Chandola.
- Aimed to investigate the link between workplace stress and CHD.
- Used a sample of over 10,000 male and female civil servants in the UK ages 35-66.
- Data collection included questionnaires, salivary sample and behavioural assessments.
- Results portrayed significant association between greater work stress and higher risk of CHD for those aged 37-49.
- Conclusion: work stress that is continuous over a period of time is a risk factor for CHD.
Explain personality as a source of stress.
- Friedman and Rosenman conducted a longitudinal study to test their hypothesis that type A personality could predict heart disease.
- Gave a questionnaire to 3,000 men ages 39-59 to classify them between personality A and B.
- After 8 and a half years, findings showed that 257 participants developed CHD, 70% being type A personality.
State traits of type A personality.
- Competitiveness
- Self-critical
- Time urgency and impatient
- Hostility
State traits of type B personality.
- Relaxed
- Patient
- Easy-going
- More tolerant of others
Measuring stress through heart rate.
- Can be measured through an ECG or by a nurse placing two fingers on the patients inner wrist and counting the beats per minute.
- Increased heart rate indicates acute stress.
- Decreased heart rate indicates chronic stress.
Measuring stress through brain function.
- MRI is a scanning machine which can detect and record brain activity.
- Work by recognising blood oxygenation changes since blood flows to the active areas of the brain.
Explain Wang’s example study.
- Aimed to investigate how different parts of the brain are associated with psychological stress by using MRI.
- 32 participants; 25 experimental condition and 7 control conditions.
- Participants had 4 scans of 8 minutes each differing in stress levels.
- Completed a self report stress scale from 1-9 and checked for saliva and heart rates.
- Results portrayed the brain exhibited continued activation during and after stress tasks indicating its role in stress responses.
Explain measuring stress through sample tests.
- Salivary cortisol
- Cortisol is released by adrenal glands as part of our fight or flight response.
- Can be measured through urine or saliva.
- higher levels indicate physiological stress.
Explain Evan and Werner’s example study.
- Investigated how density and proximity of other train passengers affect stress in 208 American commuters.
- Self reported stress levels on a 5 point likert scale.
- Took saliva samples during their morning commute and on the weekend from home.
- Recorded the difference in cortisol which showed the proximal crowding lead to higher cortisol and self reported stress levels.
Explain measuring stress through Friedman and Rosenman’s personality test.
- Questionnaire which includes a series of statements about typical behaviours and attitudes.
- Responses are rated on a likert scale.
- Responses which portray type A traits and type B traits are added and a total score is given.
Explain managing stress using biofeedback.
- Based on the principles of operant conditioning.
- Uses technology to enable the individual to see/hear physiological reactions that are occurring when under stress.
- Taught relaxation techniques and uses them while listening to their feedback.
- This will be rewarding to the individual as they have achieved their goal, reinforcing them to carry on using relaxation techniques.
Explain budzynski and stova’s example study
- Aimed to investigate results of using biofeedback.
- 15 participants were allocated to 3 groups (experimental condition, control 1 -no feedback, control 2 - irrelevant feedback.)
- Findings suggest biofeedback in the form of immediate accurate information about bodily stress may be a useful tool in behavioural therapy.
Explain the key study by bridge.
( aim - methodology - sample - procedures - results - conclusions )
- to investigate the effects of imagery on reducing stress in women undergoing radio therapy.
- RCT and completed Leeds general scale questionnaire and mood states questionnaire.
- opportunity sample of 139 women who had completed at least one radiotherapy session.
- were seen weekly for 6 weeks, were allocated to three conditions (control, relaxation training, relaxation + imagery).
- relaxation + imagery exhibited greatest effects at reducing mood disturbances.
Describe the 3 phases of stress inoculation training.
- conceptualisation phase - forming a good relationship and teaching client about stress and anxiety.
- skill acquisition phase - help clients acquire new coping skills and become conscious of their negative thought patterns.
- rehearsal and application - transfer skills into daily life through imagery and role plays along with homework tasks and feedback to the trainer.
