TWO APPROACHES TO
HEALTH AND ILLNESS
biomedical model:
A perspective that focuses on illness rather than on health,
explaining illness in terms of biological factors without
regard to psychological and social factors.
biopsychosocial model:
A perspective that focuses on health as well as illness and
holds that both are determined by a combination of
biological, psychological, and social factors.
health psychology:
The field concerned with the psychological factors that
contribute to health, illness, and recovery.

One of the MDs I’ve worked with made the
following observation:
When my father was in medical school, he was
taught that the cause of illness & death was infection.
When I was in medical school, I was taught the cause
of illness & death was chronic illness.
In 30 years of medical practice, I have come to
believe that dad was right. The cause of illness &
death is infection.
What is health psychology?
The field within psychology devoted to
understanding psychological influences on
how people stay healthy, why they
become ill, and how they respond when
they do get ill”
 Health psychologists study psychological
factors associated with health and illness,
and they promote interventions that foster
good health and aid recovery from illness.

How would you define stress?
Is stress
 something in the environment?
 a physiological or psychological reaction that
occurs within a person?
 something we should avoid at all costs?
Different ways to View Stress

LIFE STRESS SCORES

skills and a healthy well life style.
300 & up High susceptibility to stress-related illness
Daily practice of relaxation skills is very important
for your wellness. Take care of it now before a
serious illness erupts or an affliction becomes worse.
The Definition of Stress
Stress is:
the physiological and psychological
response to a condition that threatens or
challenges the individual and requires
some form of adaptation or adjustment.
Fight or Flight?




An early, classic contribution to stress research was made by Walter
Cannon (1932), who described the fight-or-flight response.
When an organism perceives a threat, the sympathetic nervous
system and the endocrine glands prepare the body to fight the threat
or flee from it.
This fight-or-flight response helps the organism respond rapidly to
threats.
However, it is potentially harmful
if an organism can't fight or flee
experiences prolonged stress and continuing physical arousal.
Hans Selye (1907–1982)
Researcher most prominently associated
with the effects of stress on health
 Established the field of stress research.
 Wrote several books including:

Criticisms of Selye’s Theory:
Identified Issues
Thanks to Selye, the connection between
extreme, prolonged stress and certain diseases
is now widely accepted by medical experts
 Critics say Selye’s model was primarily
formulated from research on laboratory rats.
 Individual variation in rats stressors response
is much less than individual variation in
human stress responses.

Criticisms of Selye’s Theory:
A Missing Cognitive Factor



The major criticism: Selye’s claim that the intensity
of the stressor determines the physical reaction to it.
His theory does not provide for a psychological
component—how a person perceives and evaluates a
stressor.
This criticism led to the development of the cognitive
theory of stress.
Lazarus’s
Cognitive Theory of Stress
In responding to the criticism of Selye’s
theory, Lazarus contends that it is not the
stressor itself that causes stress, but a
person’s perception of the stressor.

Lazarus and Folkman’s
Psychological Model of Stress
Lazarus and Folkman emphasize the importance of a
person’s perceptions and appraisal of stressors. The
stress response depends on the outcome of the primary
and secondary appraisals, whether the person’s coping
resources are adequate to cope with the threat, and how
severely the resources are taxed in the process.

There is research support for Lazarus and Folkman’s
claim that the physiological, emotional, and
behavioral reactions to stressors depend partly on
whether the stressors are appraised as challenging or
threatening.
Tomaka and others (1993) found:
Active coping with stressors appraised as challenging was
associated with increased heart rate, better performance,
and positive emotions.
Active coping with stressors appraised as threatening was
related to increased blood pressure, poorer performance,
and negative emotional tone.
