STRESS
MANAGEMENT
In our
previous lecture, we discussed several
methods that are helpful in
reducing the potential for
stress
and,
thereby, benefiting health. These methods
take advantage of the stress-moderating
effects of social
support,
personal control, exercise, being
well organized, and being
prepared for an impending
stressor. In
this
lecture we will consider
ways to reduce the reaction to stress
once it has begun.
Reducing
Stress Reactions: Stress
Management
People
acquire coping skills through
their experiences, which may
involve strategies they have
tried in the
past
or methods they have seen
others use. But sometimes
the skills they have learned
are not adequate
for
a
current stressor because it is so strong,
novel, or unrelenting. In some
cases, the approaches they
have
acquired
reduces stress in the short run-- as alcohol or
cigarette smoking can
do--but are not adaptive
and
increase
stress in the long run.
These problems in coping often
arise in individuals whose
potential for stress
is
high because of a lack of
social support, personal control,
and so on; but coping
problems also happen
among
people whose potential for
stress is relatively low. When people
cannot cope effectively, they
need
help
in learning new and adaptive
ways of managing
stress.
Many
techniques are available to
help individuals manage
stress. These stress
management techniques
are
mainly
psychological, but pharmacological
approaches are also used
sometimes under medical
supervision.
Medication
Of
the many types of drugs
physicians prescribe to help
patients manage stress, we
will consider two:
Benzodiazepines
and
Beta-blockers.
Both
of these drugs reduce physiological
arousal and feelings of anxiety.
Benzodiazepines appear to work
by
activating
a neuro-transmitter that decreases neural
transmission in the central nervous
system. Beta-
blockers
appear to block the activity of
sympathetic neurons in the peripheral
nervous system that
are
stimulated
by epinephrine and
nor-epinephrine.
Beta-blockers
cause less drowsiness than
benzodiazepines, probably because they
act on the peripheral
rather
than central nervous system.
Using drugs to manage stress should be
only a temporary measure,
either
to help during an acute
crisis, such as in the week or
two following the death of a
loved one, or while
the
patient learns new
psychological methods for coping.
But more and more people
are relying on drugs
for
long-term control of their
stress and emotions.
Behavioral
and Cognitive Methods
Psychologists
have developed methods they can
train people to use in coping with
stress. Some of these
techniques
focus mainly on the person's behavior,
and some emphasize the
person's thinking
processes.
People
who use these methods
usually find them
helpful.
Relaxation
The
opposite of arousal is relaxation--so relaxing should
be a good way to reduce
stress. "Perhaps so,
you
say,
but when stress appears,
relaxing is easier said than
done. Actually, relaxing when under
stress is not so
hard
to do when you know how. One
technique people can learn to
control their feelings of tension
is
called
progressive muscle relaxation (or
just progressive relaxation), in which
they focus their attention
on
specific
muscle groups while alternately
tightening and relaxing these
muscles.
The
idea of teaching people to relax
their skeletal muscles to
reduce psychological stress
was proposed
many
years ago by Edmund Jacobson
(1938). He developed a device to measure
electrical activity in
muscle
fibers.
Using this device, he found that people
would reduce the tension in their
muscles when simply asked
to
"sit and relax." He later
found that muscle tension could be
reduced much more if the
subjects were
94
Health
Psychology PSY408
VU
taught
to pay attention to the sensations as
they tense and relax
individual groups of muscles.
Research
findings
indicate that one reason
muscle relaxation reduces psychological
stress is that the technique
tends
to
arouse pleasant thoughts in the
person.
Although
there are various versions
of the progressive muscle relaxation
technique, they each outline
a
particular
sequence of muscle groups
for the person to follow.
For example, the sequence
might begin with
the
person relaxing the hands, then the
forehead, followed by the lower
face, the neck, the stomach,
and,
finally,
the legs. For each muscle
group, the person first tenses the
muscles for 7--10 seconds,
and then
relaxes
them for about 15 seconds; paying
attention to how the muscles
feel. This is usually
repeated for the
same
muscle group two or three
times in a relaxation session, which
generally lasts 20 or 30 minutes.
The
relaxation
technique works best in a quiet, non-distracting
setting with the person
lying down or sitting
on
comfortable
furniture.
Stress
management has been applied mainly
with adults, but children
also experience stress
without being
able
to cope effectively. Fortunately,
many behavioral and cognitive
methods are easy to learn
and can be
adapted
so that an adult can teach a
young child to use them. Relaxation
exercises provide a good
example.
An
adult could start by showing the
child what relaxing is like by lifting
and then releasing the arms
and legs
of
a rag doll, allowing them to
fall down: Then, the adult
would follow a protocol, or
script, giving
instructions
to relax. When children and
adults first learn
progressive muscle relaxation, they
sometimes
don't
actually relax their muscles
when told to do so. Instead of
letting their arms and
legs fall down, they
move
them down.
They
also sometimes tense more
muscles than they are asked
to--for example, tightening
facial muscles
when
they are supposed to tense
only hand muscles. These
errors should be pointed out
and corrected.
Often,
after individuals have thoroughly
mastered the relaxation procedure, they
can gradually shorten the
procedure
so they can apply a very quick version in
times of stress, such as when they
are about to give a
speech.
This quick version might have the
following steps: (1) taking
a deep breath, and letting it
out; (2)
saying
to oneself, "Relax, feel nice and calm";
and (3) thinking about a
pleasant thought for a few
seconds.
In
this way, relaxation methods can be
directly applied to help people cope
with everyday stressful
events.
Research
has demonstrated that
progressive muscle relaxation is highly
effective in reducing stress.
What's
more,
people who receive training in relaxation
show less cardiovascular reactivity to
stressors and
stronger
immune
function.
Systematic
Desensitization
Although
relaxation is often successful by itself
in helping people cope, it is frequently
used in conjunction
with
systematic desensitization, a useful
method for reducing fear
and anxiety. This method is based on
the
view
that fears are learned by
classical conditioning--that is, by
associating a situation or object with
an
unpleasant
event. This can happen, for
example, if a person associates
visits to the dentist with pain,
thereby
becoming
"sensitized" to dentists.
According
to Joseph Wolpe, an originator of the
desensitization method, the reversal
comes about through
the
process of counter-conditioning, whereby
the "calm" response gradually
replaces the "fear"
response.
Desensitization
has been used successfully
in reducing a variety of children's and
adults' fears, such as
fear
of
dentists, animals, high
places, public speaking, and
taking tests.
An
important feature of the systematic
desensitization method is that it
uses a stimulus hierarchy--
a
graded
sequence of approximations to the conditioned
stimulus, the feared situation. The
purpose of these
approximations
is to bring the person gradually in
contact with the source of
fear in about 10 or 15
steps.
To
see how a stimulus hierarchy
might be constructed, we will
look at the one in the following
example that
deals
with the fear of dentists.
The person would follow the
instructions in each of the 14
steps.
95
Health
Psychology PSY408

Example
of a Stimulus Hierarchy for a Fear of
Dentists
1.
Think about being in the dentist's
waiting room, simply accompanying
someone else who is there
for an
examination.
2.
Look at a photograph of a smiling person
seated in a dental chair.
3.
Imagine this person calmly having a
dental examination.
4.
Think about calling the dentist for an
appointment.
5.
Actually call for the
appointment.
6.
Sit in a car outside the
dentist's office without having an
appointment.
7.
Sit in the dentist's waiting
room and hear the nurse
say, `The hygienist is ready
for you'.
8.
Sit in the examination room and
hear the hygienist say, -I see one
tooth the dentist will need to
look at.
9.
Hear and watch the drill
run, without its being
brought near the
face.
10.
Have the dentist pick at the tooth
with an instrument.
11.
See the dentist lay out the instruments,
including a syringe to administer an
anesthetic.
12.
Feel the needle touch the
gums.
13.
Imagine having the tooth
drilled.
14.
Imagine having the tooth
pulled.
As
you can see, some of the
steps involve real-life, or in vivo,
contacts with the feared situation
and some
do
not. Two types of
non-real-life contacts, of varying
degrees, can be included. One type uses
imaginary
situations,
such as having the person think about
calling the dentist. The other involves
symbolic contacts,
such
as by showing pictures, films, or models of the
feared situation.
The
systematic desensitization procedure
starts by having the person do relaxation
exercises. Then the
steps
in
a hierarchy are presented
individually, while the person is
relaxed and comfortable. The
steps follow a
sequence
from the least to the most
fearful for the individual.
Each step may elicit
some wariness or fear
behavior,
but the person is encouraged to
relax. Once the wariness at
one step has passed
and the person is
calm,
the next step in the hierarchy
can be introduced.
Completing
an entire stimulus hierarchy and
reducing a fairly strong
fear can be achieved fairly
quickly--it
is
likely to take several
hours, divided into several
separate sessions. In one
study with dental-phobic
adults
who
simply imagined each step in a hierarchy,
the procedure successfully reduced
their fear in six 1
1/2-
hour
sessions. Individual sessions
for reducing fears in children
are usually much shorter
than those used
with
adults, especially for a
child who is very young and
has a short attention
span.
Biofeedback
Biofeedback
is a technique in which an
electromechanical device monitors the
status of a person's
physiological
processes, such as heart
rate or muscle tension, and immediately
reports that information
back
to
the individual. This information enables
the person to gain voluntary
control over these
processes
through
operant conditioning. If, for
instance, the person is trying to
reduce neck-muscle tension and
the
device
reports that the tension has just
decreased, this information reinforces
whatever efforts the
individual
made
to accomplish this decrease.
Biofeedback
has been used successfully
in treating stress-related health problems.
For example, an
experiment
was conducted with patients
suffering from chronic muscle-contraction
headaches. Those who
were
given biofeedback regarding muscle tension in
their foreheads later showed
less tension in those
muscles
and reported having fewer headaches
than subjects in control
groups. What's more, these
benefits
continued
at a follow-up after 3 months. Biofeedback
seems to be about as effective as progressive
muscle
relaxation
methods for treating
headache.

Modeling
People
learn not just by doing,
but also by observing. They see what
others do and the consequences of
the
behavior
these models perform. As a
result, this kind of learning is called
modeling, and sometimes
"observational"
or social learning.
People
can learn fears and
other stress-related behavior by
observing fearful behavior in other
individuals.
In
one study, children (with
their parents' permission)
watched a short film showing a 5-year-old
boy's
reaction
to plastic figures of the cartoon
characters Mickey Mouse and
Donald Duck. In the film
when the
boy's
mother showed him the Mickey
Mouse figure, he screamed and withdrew;
but when she showed
him
the
Donald Duck figure, he remained
calm and displayed no
distress. While the subjects
watched the film,
physiological
measures of stress were
taken, confirming that the
children were more aroused
while watching
the
episode with Mickey Mouse
(fearful) than while watching the one
with Donald Duck. After the
children
watched
these scenes, they each participated in a
task that involved the two
figures from the film. At
this
time,
they tended to avoid the Mickey Mouse
figure (the stressful one) in
favor of Donald Duck.
Since
people can learn stressful
reactions by observing these behaviors in
others, modeling should be
effective
in reversing this learning and helping
people cope with stressors,
too. A large body of
research has
confirmed
that it is. The therapeutic
use of modeling is similar to the method of
desensitization:
The
person relaxes while watching a model
calmly perform a series of activities
arranged as a stimulus
hierarchy--that
is, from least to most
stressful. The modeling procedure
can be presented symbolically,
using
films or videotapes, or in vivo,
with real-life models and
events.
Approaches
Focusing on Cognitive
Processes
Because
stress results from
cognitive appraisals that
are frequently based on a
lack of information,
misperceptions,
or irrational beliefs, some
approaches to modify people's
behavior and thought
patterns
have
been developed to help them cope better
with the stress they experience. To
achieve this goal,
these
methods
guide people toward what Arnold
Lazarus (1971) has called a
"restructuring" of their
thought
patterns
or "Cognitive Restructuring".
Cognitive
restructuring is a process by which
stress-provoking thoughts or beliefs are
replaced with more
constructive
or realistic ones that
reduce the person's appraisal of threat
or harm.
A
widely known approach that
focuses on cognitive restructuring is
rational-emotive therapy (RET),
which
was
developed by Albert Ellis. RET is
based on the view that
stress often arises from
faulty or irrational
ways
of thinking. These ways of
thinking affect stress appraisal
processes, increasing the appraisal of
threat
or
harm.
To
illustrate how irrational thoughts can
increase stress and lead to
psychological problems, consider
the
case
of a college baseball player, nicknamed
Bart," who was not
hitting up to expectations, and
was very
depressed
about his poor performance. In
talking with Bart, it quickly
became apparent that his
own
expectations
were unrealistic.
For
instance, Bart wanted to hit the
ball so hard that it would
literally be bent out of
shape (if someone
happened
to find it in the next county!).
After a particularly bad batting
session, he would go home
and
continue
to practice until he was
immobilized with exhaustion.
Simply put, he believed that if an
athlete was
not
performing well, this could only
mean he was not trying hard
enough.
Bart's
therapy involved progressive muscle
relaxation and cognitive methods to
help him realize
two
important
things. First, although motivation and
desire do increase performance, they do
so only up to a
point,
after which additional motivation
impair performance. Second,
although hitting very well is
nice,
97
Health
Psychology PSY408
VU
hitting
moderately well is not
"terrible" or "intolerable". These
realizations restructured Bart's
thinking
about
his performance, and his
batting average increased dramatically.
Similar methods can help
people
reduce
irrational thoughts that lead to
their debilitating feelings of anxiety
and depression.
There
are other approaches also to
manage stresses that include
Meditation, Hypnosis, and Massage.
These
approaches
are and can be used in
conjunction with the techniques
described above. But we will
not go into
the
details of these approaches
here.
