Week 9 Flashcards
Health Belief Model
– Suggests that health behaviours are predicted by
four factors:
• Perceived susceptibility to a health threat
• Perceived seriousness/severity of a health threat
• Benefits and barriers of undertaking particular health
behaviours
• Cues to action
Protection Motivation Theory of Health
– Health Belief Model + self-efficacy
Theories of health behaviour
• Theory of Reasoned Action
– a socio-cognitive view
– an individual’s attitudes toward a health
behaviour and subjective norms influence their
intentions to perform the behaviour
• Theory of Planned Behaviour
– Theory of Reasoned Action + self-efficacy
Stress
Stress refers to a challenge to a person’s
capacity to adapt to inner and outer demands.
• Stressful experiences typically produce
physiological and emotional arousal.
• Stressful experiences typically elicit cognitive
and behavioural efforts to cope with the stress
Lazarus’s model of stress
– Primary Appraisal: deciding on the significance or
meaning of the event
– Secondary Appraisal: evaluate our ability to cope and
decide how to respond
• Three types of stress (Lazarus, 1981):
– harm or loss
– threat
– challenge
Peripheral nervous system
Autonomic nervous system and sympathetic nervous system
Autonomic nervous system
The autonomic nervous system is concerned
with the regulation of smooth muscle (eg.
skin, blood vessels, walls of the gut), cardiac
muscle, and glands
Divisions of the ANS:
• The sympathetic division is most involved in activities associated with the expenditure of
energy from reserves stored in the body.
• The parasympathetic division supports
activities that are involved with increases in
the body’s supply of stored energy
The HPA Axis
Acronym heaven… • HPA: hypothalamicpituitary- adrenal • CRF: corticotropin releasing factor • ACTH: adrenocorticotropic hormone
Stress as a psychobiological
process
– Alarm: Release of adrenalin and other hormones
(fight or flight response)
– Resistance: Respiration and heart rate return to
normal, glucose levels and some stress-related
hormones remain high
– Exhaustion: After prolonged stress the body’s
defences break down, increased vulnerability to
infection/disease
