HEALTH
PSYCHOLOGY
·
The
branch of psychology that
focuses upon the role of
psychological factors in
the
development
and prevention of illness, in
coping with disease, and in
health promotion.
·
The
branch of psychology that
studies the relationship
between psychological variables
and
well-being
of a person.
According
to Brannon and Fiest (2000)
·
Health
psychology is the branch of
psychology that concerns
individual behaviors
and
lifestyles
affecting a person's physical
health.
·
Health
psychology includes psychology's
contribution to the enhancement of
health, the
prevention
and treatment of disease,
the identification of health
risk factors, the
improvement
of
the health care system,
and the shaping of public
opinion with regard to
health.
A
health psychologist works in the following
areas:
Enhancement
of health
Prevention
of disease
Treatment
of disease
Identification
of risk factors
Improvement
of the health care system
Shaping
public opinion regarding
health
Understanding
Health
In
order to understand the
modern concept of health, we
need to consider some
questions:
·
How
would you define
health?
·
Who
is a healthy person?
·
Can
lifestyles be healthy and
unhealthy?
According
to the World Health organization
(WHO):
HEALTH
is " a state of complete physical, mental, and
social well being and not
merely
the
absence of disease or
infirmity".
·The
modern approach towards health is more
prevention - oriented rather than
treatment oriented.
Emergence
of Health Psychology
·
American
Psychological Association established
its Division 38, Health
Psychology, in 1978.
·
This
was the formal establishment of
health psychology as a separate
discipline.
Facts
leading to this newer definition and
approach
a.
The leading causes of death
today are no more infectious diseases,
but lifestyle related
diseases:
implying
that they are preventable.
b.
The escalating costs of health
care have led to the realization that
these costs could be controlled,
even
reduced,
by preventive strategies.
c.
The dissatisfaction with the existing
medical model has been on a
constant increase.
·
Dissatisfaction is primarily based on the
observation that a person, even after
taking proper medication
and
receiving full medical care
may still not be feeling
healthy.
·
This implies that something
else may also be
contributing to one's well-being. d.
Research on the role
of
psychological factors in health
and illness:
·
It
was observed that psychological
factors have a role in
physical illness.
233
Introduction

·
Also,
psychological interventions are
helpful in altering physiological
conditions and
symptoms.
·
Today
there is a growing consensus
that health is essentially an
individual responsibility '.
No
community or state can give health BUT
the required facilities.
No
improvement in the health care
system can be efficacious
unless the citizens
assumes
responsibility
for their own well
being.
Different
psychological theories and
models have tried to explain health
related beliefs and
behaviors.
·
The
Health-Belief Model
·
The
Protection Motivation
Theory
·
The
Theory of Planned Behavior
·
Self
Regulatory Model
·
Self
Efficacy Theory
All
explanations agree on one
point i.e.
A
person's health, as well as the feeling of being
healthy, depends to a large extent, on
how much control
does
one feel over one's life,
circumstances and health.
Health
or a State of Complete Well-Being has to be
earned and maintained by the Individual
himself, who
must
accept this Responsibility
Some
Psychological Variables Affecting
Health
Health
Locus of Control
Who
is responsible for an individual's
degree of health or illness? ...The
doctors, family/ friends, fate,
or
the
person himself?
Perceived
Control
The
tendency to feel or experience responsibility
about the personal health related
acts and behaviors,
as
well
as the ability to get the desired
outcomes.
Self
Perceptions of Wellness
The
individual's personal feeling and
evaluation of experiencing well-being, especially in
comparison with
others.
·Wellness dimensions include; emotional, intellectual,
physical, social, spiritual, and
general
dimensions.
Learned
Helplessness
Proposed
by Martin Seligman.
It
is a belief that one has no
control over the
environment.
People
conclude that unpleasant or
aversive stimuli cannot be
controlled.
This
pattern becomes so ingrained that they do
not try to remedy the
aversive circumstances even if
they
actually
can exert some influence.
Health
and Principles of Behavior
Change
·
Classical
conditioning
·
Operant
conditioning
·
Observational
learning
Classical
conditioning
·
Many
health-related behaviors are a
result of classical
conditioning:
·
Fear
of going to a doctor or
dentist
·
Fear
of surgical procedures
·
Fear
of swallowing medicine
·
Bulimia
and Anorexia Nervosa: Fear
of gaining weight after
eating even in small

234
Introduction

Operant
conditioning
·
A
number of health-related behaviors
depend on operant
conditioning:
·
Children
tend to over-eat when
mothers encourage them for
eating.
·
Teenagers
may begin drug abuse or
smoking when peers dare
them to try a drug or a
cigarette.
·
Many
people exercise regularly
because others appreciate
their physical
fitness.
Observational
Learning
·
Drug
addiction usually results
from observational
learning.
·
People
whose peer's exercise
regularly tend to indulge in
regular exercise.
·
Children
may go for surgical
procedures without fear if
they observe other children
doing the
same.
Stress,
Health, and Illness
·
Stress
is
the response of an organism to
events that are threatening
or challenging.
STRESSORS:
circumstances that produce
threats to our well-being
(e.g. death of a loved
one,
marriage,
exams, illness).
·
Uplifts:
Minor
positive events that make
one feel good e.g.
seeing an old friend,
feeling healthy,
completing
a task.
·
Daily
Hassles are
also a source of stress.
The
Nature of Stressors
There
are three general classes of
events that can be seen as
stressful:
A.
Cataclysmic Events
B.
Personal Stressors
C.
Background Stressors
A.
Cataclysmic Events
Strong
stressors that occur
suddenly affecting many people at once
e.g., natural disasters.
Once
they are over people can
look forward to the future,
knowing that the worst is behind
them.
But
at times the victims may experience
POSTTRAUMATIC STRESS DISORDER
i.e.,
Re
-experiencing the original stress event
and associated feelings in
flashbacks or dreams
B.
Personal Stressors
·Major
life events that have
immediate negative consequences,
which generally fade with
time (e.g. death of
a
loved one, loss of job,
broken love affair).
C.
Background Stressors
Daily
hassles causing minor irritations
but have no long-term ill
effects unless they continue or
are
compounded
by other stressful
Manifestations
of Stress
A.
Psychological: tension, anxiety,
depression, and
helplessness.
B.
Physiological:
Psychosomatic
disorders i.e., medical
problems caused by an interaction of
emotional,
psychological,
and physical difficulties
(allergies, aches and pains,
flu).

may partially determine the
course of their
disease.

with longevity of life.
Cancer
and Stress
Research
evidence supports the hypothesis
that stressors have a role
to play in the onset of cancer.
Smoking
Cigarette
smoking has been found to be
associated with stress,
which in turn is associated
with heart
disease,
cancer, and a number of other
diseases

Measuring
Stress
·
Major
life events may be used as
indicators of the stress one
experienced.
·
The
Social Readjustment Rating
Scale by Holmes and Rahe is
one of the assessment tools
that
can
indicate the stress related
risk that one may be
facing.
Understanding
Stress
General
Adaptation Syndrome Model
A
model explaining the course of stress.
Proposed by Hans
Selye.
It
suggests that a person's
response to stress consists of
three stages:
a)
Alarm and mobilization
stage: a person's initial
awareness of the presence of a
stressor.
b)
Resistance stage: coping with the
stressor.
c)
Exhaustion stage: failure to
adapt to a stressor leading to
physical, psychological, and
emotional
problems.
Coping
With Stress
The
efforts to control, reduce, or
learn to tolerate the threats that
lead to stress.
