Stressed Defined

  • The bodies response to a perceived challenge or threat

  • Stress is cumulative in nature

  • The effect of stress is influenced by cognitive processes

  • Appraisals of stressors are subjective

3 Parts of Stress

Stress as a Stimulus

Eustress:

  • Desirable stress

  • E.g. Getting married, going on a holiday, starting a new job

Distress:

  • Undesirable stress

  • E.g. being fired, getting divorced, being bereaved

  • Some distress may be counterbalanced by enjoyable transactions

Stress can be measured in (LCU) Life Change Units.

  • 11 - 150 : low to moderate chance of becoming ill in near future

  • 150 - 299 : moderate to high chance of becoming ill in future

  • 300 - 600 : high or very high risk of becoming ill in near future

Transactional Model of Stress

3 Types of Stress

Yerkes Dodson Law (1908)

Emotional responses

  1. Stressor (the stimulus)

    • The bodies response to a perceived challenge or threat

    • Can be acute (short-term) or chronic (long-term)

  2. Stress response

    • physiological and psychological

  3. Coping

    • Adaptive or maladaptive

Primary appraisal:

  • Assesses the quality and nature of the stimulus

  • The stressor may be appraised as:

    • a threat,

    • a challenge,

    • or benign

  • The same stressor may be appraise differently by different people

Secondary appraisal:

  • Assesses the person’s resources and ability to cope with the stressor

  • Resources may be:

    • Internal – strength, determination.

    • External – social support, money

Acute (Short-term):

  • A quickly dissipating reaction to an immediate threat

  • Usually triggers the fight – flight – freeze – fawn response

Intermittent:

  • Response to a stressor that varies in duration

  • Associated with physiological toughening and resilience

  • E.g. being at university

Chronic (long-term):

  • Common to modern ways of life

  • Leads to negative health impacts

  • E.g. financial worries, occupational demands, etc

Stress as a Response

  • Strong link between appraisals and emotional responses

  • E.g. helplessness leads to sadness

  • Positive emotions can reduce adverse physiological effects

Physiological responses

  • Fight – Flight – Freeze – Fawn

  • The autonomic nervous system is the preparing for survival

  • Maybe adaptive in context, but less adaptive for long-term stressors

General Adaptation Syndrome (GAS)

  1. Alarm stage: recognise the threat and mobilise resources

  2. Resistance stage: stress is prolonged and physiological arousal stabilises, but is still above baseline as a coping mechanism

  3. Exhaustion stage: the bodies resources are depleted

Behavioural responses

We seek to master, reduce, tolerate, or avoid the demands created by stress

This may involve:

  • Learned helplessness

  • Aggression or frustration

  • Escapism

  • Conscious or unconscious defence mechanisms

  • Constructive coping/self-care – confronting problems directly
