Psychology
works for Phobias
What is a Phobia?
A phobia is an excessive and persistent fear of
:a situation (e.g., enclosed places, driving, flying, seeing blood,
heights) or an object (e.g., animals such as rats, snakes, spiders,
dogs, or birds).
The focus of an individual’s fear is generally
anticipated harm or danger related to the situation or object (e.g.,
having an accident while driving, being bitten by a dog), or fear
of losing control and having anxiety-related physical sensations
(e.g., panicking in an enclosed place, fainting upon seeing blood).
The fear is considered excessive because it is
out of proportion to the actual level of danger associated with
the situation. When an individual with a phobia is exposed to the
feared stimulus (the object or the situation) or related cues (things
that remind us of the object or situation), an immediate anxiety
response is triggered that can sometimes grow into a full-blown
panic attack. Consequently, people with phobias either avoid the
feared situations or objects or they endure a lot of distress.
For example, an individual with a phobia of snakes experiences
an anxiety reaction in a number of situation including seeing a
snake on television, being outside in grassy or wooded areas where
snakes may live, and seeing things that resemble a snake such as
a coiled garden hose in the yard.
Phobias are quite common and occur in about one
in every 10 Canadians. There are four main types of phobias: animal
type (e.g., spiders, dogs, rodents), natural environment type (e.g.,
storms, lightening, water), blood-injection-injury type (e.g., seeing
blood, getting a needle, having a medical procedure), and situational
type (e.g., enclosed places, flying, driving). Phobias that do not
fit into these four categories fall into a fifth category referred
to as "other type" (e.g., fears of choking or vomiting).
Blood-injection-injury and animal phobias typically
begin in early childhood whereas situational and natural environment
phobias begin later, usually in the late teens and 20s. Approximately
75% of individuals with a blood-injection-injury phobia report a
history of fainting in response to the phobic stimulus.
These features are outlined in the Diagnostic and Statistical Manual
of Mental Disorders, Fourth Edition Text Revision; American Psychiatric
Association (2002).
- Exposure to the feared stimulus triggers an excessive fear reaction
- Recognition that the fear is excessive or out of proportion
(although children need not meet this requirement)
- Exposure to the feared stimulus is avoided or endured with
intense distress
- Fear is present for at least 6 months if the individual is under
the age of 18
- The fear causes significant distress to the individual or interferes
with daily social and/or occupational activities
Phobias have a strong effect on a person’s
life. Phobias cause a lot of distress and/or make it very difficult
to function normally in social situations and at work. For example,
an individual with a snake phobia may avoid pleasant activities
such as gardening, nature walks, camping or playing a game in a
field. A person with a fear of heights may not take a job in an
office on a high floor of an office tower. A person with a fear
of flying may turn down a promotion because the new position requires
flying to meetings across the country. An individual with a fear
of needles or medical procedures may avoid necessary treatments
or routine blood tests because of their phobia, putting their health
at risk.
Although many phobias are triggered by experiencing
a traumatic event in the phobic situation (e.g., getting stuck in
an elevator or having a panic attack while flying), a number of
individuals do not remember a specific time or event that caused
their fear and report a more gradual development. Thus, there are
a number of ways to develop a phobia, including "direct conditioning"
(being frightened in the situation or by the object), "vicarious
acquisition" (actually witnessing a frightening event in the
phobic situation or seeing someone else who is afraid in the phobic
situation), and informational transmission (e.g., hearing about
a scary event in phobic situation through the media or a family
member).
We are more likely to develop fears of some objects
and situations than others. For example, it is much easier to develop
a fear of a snake than a flower. In fact, our fear of snakes may
have helped us to survive over the centuries. Our own unique personality
factors (such as a disgust reaction to certain stimuli) and our
stress levels at the time of a traumatic event can also lead to
the development of a phobia.
What Psychological Approaches are Used to Treat
Phobias?
The treatment of choice for specific phobias is
cognitive behaviour therapy (CBT). It focuses on slowly and safely
exposing a person to the feared situation or stimulus. This is called
an exposure-based treatment, which involves repeated approaching
of the fear-provoking situation or object until it no longer produces
a strong fear reaction. Many studies have shown that exposure-based
CBT is highly effective for the treatment of specific phobias. In
fact, specific phobias are considered to be the most treatable of
the anxiety disorders. Significant improvement or full recovery
can occur in as little as one session of guided exposure lasting
2-3 hours. This form of treatment has been used for adults, adolescents,
and children. CBT has been found to be effective when administered
in a self-help book format as well.
Generally, medications are not considered effective
for the treatment of specific phobias. However, it is not uncommon
for individuals with phobias to be prescribed low dosages of benzodiazepines
(anti-anxiety medication) to be taken in the phobic situation (e.g.,
when flying). Although this will not eliminate the fear, it allows
the person to function in the situation. Situational phobias (e.g.,
claustrophobia) that share many features with panic disorder may
also respond to antidepressants proven useful in treating panic
attacks. Preliminary studies suggest that selective serotonin reuptake
inhibitors (SSRIs) may play a role in reducing fear and anxiety
levels. However, CBT is considered superior to medications in the
treatment of specific phobias.
