Individual differences: social models of health and illness Flashcards
How did WHO define health?
Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity
How does the DSM-V define illness?
A behavioural or psychological syndrome or pattern that occurs in an individual
What are causal relationships between PID and health and illness? (example)
- PID plays a role in causing illness
- Illness plays a role in causing change in PID
Personality->illness:
PID -> biological activities -> illness
psychosomatic
eg. anxiety -> anorexia/weight loss -> loss of bone mass
illness->personality
eg. huntingtons disease - neurodegenerative - affects cognition and motor skills - can subsequently lead to frustration, stress, anxiety, irritability and mood changes
What are correlational relationships between PID and health and illness? (example)
The same biological processes underpin traits and illness outcomes
eg. being susceptible to heart disease has a high correlation with being a hostile person BUT not causal
What is a propensity relationship between PID and health and illness? (example)
PID may result in behaviours that increase risk of illness
Personality traits may lead to risky behaviours that increase risk of illness
eg. Freud -> fixation at oral stage of psychosexual development -> smoking -> lung disease
eg. autistic people fixated on routine -> may lead to eating a poor diet -> diabetes/blood pressure
How can the relationship between PID and health/illness be assessed?
Longitudinal studies
- enables measurement of personality before onset of illness (take a long time to develop)
- by measuring before onset of illness, can analyse what type of relationship exists between PID and illness and identify subsequent supports
What are some limitations of using longitudinal studies to assess the relationship between PID and health/illness?
- requires large population sample
- Costly
- attrition of data is common
- history and maturation effects
What research did Friedman and Rosenman (1958) conduct?
Interested in predicting who would develop heart disease
- 3524 men studied over 8.5 yrs
- could not predict from physical factors alone but adding psychological factors improved prediction rates
What did Friedman and Rosenman (1958) find about type A personality and heart disease?
Coronary prone
- driven to achieve
- competitive
- hostile to competitors
- needs recognition
- works hard
- short temper
What did Friedman and Rosenman (1958) find about type B personality and heart disease?
Non-coronary prone
- relaxed
- doesnt plan ahead
- unhurried in their approach
- no desire for competition
What can hostility produce in the immune system and what can this increase risk of?
Produces higher levels of C-reactive protein which can increase risk of cardiovascular disease (Suarez et al. 2002)
Why does health psychology matter?
- Personality may influence how people deal with their illness
- attitudes towards illness/treatment can affect outcomes - eg. a person with high neurotic traits may increase focus on illness and restrict ability to get on with life
- Traits may not be consistent and stable over time so we need models to help examine interaction between individuals and their environments
How may someone with an internal locus of control deal with health and illness compared to those with external locus of control?
- feel in control of life
- feel empowered
- try to change things in their environment
External - more likely to feel powerless
- Individuals with internal LoC cope better than those with external LoC
How is locus of control measured in health-related behaviours?
internality
chance
powerful others
value placed on health
What is self-efficacy?
Influences motivation and persistence
Makes us resilient and better equipped to overcome adversity
- associated with a range of health behaviours but dependent on confidence
