Chapter 15 - Stress, health, and coping Flashcards
Stress can be viewed in three different ways:
- stimulus
- response
- as an organism-environment interaction (transaction)
Microstressors
Daily hassles
Catastrophic events
- Occur unexpectedly
* Affect large #’s of people
Major Negative Events
• Intensely stressful life events
Stressor types
- microstressors
- catastrophic events
- major negative events
Life Events Scale
- Quantify stress over a given period of time
- Indicate whether a particular event occurred
- Appraisal of being positive or negative
- Indicate amount of control, predictability
The Stress Response
- Primary appraisal = demands of situation
• What do I have to do? - Secondary appraisal = resources available to cope
• How can I cope? - Judgments of consequences of situation
•What are the ‘costs’ to me? - Personal meaning - what does the outcome imply
• What does this say about my beliefs in myself? World?
General Adaptation Syndrome = GAS
- Physiological reaction to prolonged stress
* Three Phases
Three phases of General Adaptation Syndrome = GAS
- Alarm
- Resistance
- Exhaustion
Alarm - 1st phase -similar to ‘fight or flight’
- Activates sympathetic nervous system
- Release stress hormones = Cortisol
• Triggers increase in blood sugars
• Suppresses immune system - Cannot last indefinitely
• Parasympathetic system tries to restore homeostasis
• If stressor persists - so does response!
Resistance – 2nd phase
- Continued recruitment of resources
- Can last long time, but resources being depleted
- Eventually are no longer sufficient
Exhaustion – 3rd phase
- Resources depleted
- Increased vulnerability to disease
- Can manifest itself with cardiovascular problems; immune system difficulties
Effects of stress on psychological well-being most dramatic in those who have experienced
catastrophic life events
More negative life events = more
psychological distress
• But, correlational so cannot determine causality
Neuroticism - personality trait
increased tendency to:
• experience negative emotions
• get themselves into stressful situations through their maladaptive behaviours
PTSD Symptoms
- Severe anxiety, physiological arousal (the stress response), and distress
- Painful, uncontrollable reliving of the event(s) in flashbacks, dreams, and fantasies
• Emotional numbing and avoidance of stimuli
associated with the trauma
•intense “survivor guilt” sometimes
The Residential School Syndrome
- Individuals symptoms include recurrent intrusive memories, nightmares, flashbacks
- Increased risk of alcohol and drug abuse at young age
- Emotional detachment, relationship difficulties
- Loss of and avoidance of culture, and anger issues
Stress linked with increase in
chronic conditions
- Arthritis, bronchitis, emphysema
- Stress can be precursor to health problems
Other consequences of stress
• Decrease immune function
• Demonstrated to occur within 24 hours
• Worsen pre-existing conditions
• Stress hormones contribute to blocked arteries
• Deterioration of hippocampus and memory
impairment
Vulnerability Factors
• Increase susceptibility to stress
What Reduces Resistance?
- Lack of support network
- Poor coping skills
- Pessimism
Protective Factors against stress
• Social support, coping skills,optimism
Social Support
- Blunts impact of stress
- Sense of identity, meaning
- May prevent maladaptive ways of coping
- Enhances immune system (cancer patients)
Why do some people suffer psychological and/or physiological distress and others do not?
• Hardiness
Hardiness
• Commitment - What they do is important
• Control - Control (perceived) over situation
(Strongest)
• Challenge - Situation is a challenge not a threat
Coping Self-Efficacy
• Belief we can successfully cope
Increased efficacy from: • Previous successes • Observing others • Social persuasion / encouragement • Low levels of arousal
• Increase immune system functioning
