Personality & Health: Stress & Illness Flashcards
Among psychological factors, personality has perhaps the greatest potential to predict the diseases responsible for most mortality in humans. Explain why.
The leading causes of death in adults are chronic diseases that develop slowly over a long period of time.
- the behaviours that precede and predict these chronic diseases need to be enduring or repeated to achieve lasting effects on humans.
What was the most influential prospective study to look at personality traits identified in childhood and the predictive power on health outcomes in adulthood?
Friedman et al ((1993) which utilised data from the Terman Life Cycle Study of gifted children.
What were the 6 dimensions Friedman et al constructed from Terman’s data?
- High energy
- Cheerfulness / Optimism
- Conscientiousness
- High motivation
- Sociability
- Permanency of mood
After controlling for gender what 2 personality factors did Friedman et al find to predict longevity?
Consciousness
- the strongest predictor and was positively related to longevity
Cheerfulness/ optimism
- the size effect was only slightly weaker but contrary to expectations, this dimension was inversely related to longevity
While reports of robust associations between personality and health are interesting, in order to interpret these associations we first need to consider….?
The potential causal pathways between personality and health (I.e models of association).
What are 2 models of association that argue personality moderates the relationship between stress and health?
- Unidirectional: the biological stress model (Hans Selye)
- Triadic: Transactional stress model (Richard Lazarus)
Selye argued that stress is essentially the rate of wear and tear in the body. This wear and tear was associated with….?
The non specific response of the body to any demand.
How is stress conceptualised within a unidirectional S-R framework?
- The biological stress Reaction/Response
- The environmental stressor / Stimulus
The biological stress model: Explain the biological stress reaction/response.
A set of defensive biological adjustments the body makes in response to environmental demand
The biological stress model; What is the environmental stressor?
The environmental demands that automatically triggers the biological stress reaction.
For Selye, stress was reflected in an orchestrated set of bodily adjustments that occur in response to environmental demand. These adjustments developed throughout time during continued exposure to the stressor in what Selye termed the General Adaptation Syndrome. A fully developed General Adaptation Syndrome consists of 3 stages, being?
- Alarm
- Resistance
- Exhaustion
The biological stress model: Describe the Alarm stage of Selye’s General Adaptation Syndrome.
In this initial stage stressors activate a defensive response in two great integrated mechanisms: the nervous system and the endocrine system to elicit a cascade of physiological responses.
- the sympathetic nervous system
- the hypothalamic pituitary adrenal axis
The biological stress model: Describe the Resistance stage of Selye’s General Adaptation Syndrome.
The same body systems that promote adaptation and defence can also damage one’s health. Frequent, intense or prolonged experiences of stress-induced physiological arousal can contribute to the development or progression of illness.
The biological stress model: Describe the Exhaustion stage of Selye’s General Adaptation Syndrome.
If the stressor persists long enough all of the body’s resources eventually become depleted. There is limited adaptive energy in the system which eventually becomes exhausted.
Environmental stressors have been operationalised as ;
- Major life events requiring people to make significant changes in their lives ,
- frequency of major life events,
-specific (traumatic) major life events,
Thus operationalised almost entirely in terms of frequency of major life events. However Lazarus and co workers developed a scale comprising..?
117 hassles (micro / daily hassles)
Environmental stressors: the cumulative impact of daily hassles is thought to produce …..?
The type of neuro-hormonal changes that result in stress related diseases.
