What is phobia?
Phobia (from Greek φόβος phobos, “fear”) is defined as a persistent, abnormal, irrational or in some cases disabling fear of activity, situation or specific object that leads to a definite desire of avoiding it. In medicine it is classified as a type of anxiety disorder characterized with rapid onset of fear and present for more than 6 months.
The phobic person will intensively go to great lengths and do abnormal things in order to avoid the potential cause of fear, typically to a level far greater than the actual danger posed. In cases where object or situation which are primary source of phobia cannot be avoided, the affected person will have important distress.
People who have phobias most commonly realize that their fear is irrational; however they are powerless to do anything about it. Such fears can interfere with their school, work and personal relationships. Sometimes phobia can be accompanies with panic attack or if it is specific phobia (e.g fear of blood) nausea, vomiting, trouble with breathing, fainting, loss of consciousness and other symptoms may also occur.
According to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) phobias are considered as a subtype of anxiety disorder and are divided into 3 groups:
- Agoraphobia with or without panic attacks – defined as irrational anxiety about being in places from which escape might be difficult or embarrassing. The word itself means “fear of open spaces” Patients with agoraphobia have a fear of being in large crowds or trapped outside the home. They often avoid all social situations and stay inside their homes. Many patients with agoraphobia fear that they will eventually get panic attack in a place where they can’t escape. Patients with chronic agoraphobia may have fear they will have a medical emergency in a public or where no help is available.
- Social phobia defined as irrational anxiety elicited by exposure to certain types of social or performance situations, also leading to avoidance behavior. A social phobia can be in some cases so severe that the simplest social interactions, such as answering the telephone or ordering at a restaurant can cause panic. Those with social phobia often avoid public situations in order not to get embarrassed.
- Specific phobia defined as persistent and irrational fear in the presence of some specific stimulus which commonly elicits avoidance of that stimulus, i.e., withdrawal.
There are 5 subtypes of specific phobias:
- Animal type – caused by animals or insects
- Natural environment type – cased by environmental stimuli, such as storms, heights, or water
- Blood-injection-injury type – caused by witnessing some invasive medical procedure
- Situational type – caused by a specific situation, such as elevators, tunnels, bridges, public transportation, flying, driving, or enclosed spaces
- Other type – caused from all different stimuli, such as of choking, vomiting, or contracting an illness, etc.
According to NIMH, about 11.5 million adults worldwide which is about 8.0% adults suffer from some kind of phobia.
Phobias are shown to be common psychiatric disorders. Nearly 11 % of the U.S. population which is about 25 million people may suffer from a phobia at least once during their lifetime.
Just in the U.S. about 6.8 % of the population, (about 15 million adults) suffer from social phobia annually. It has been shown that social phobias typically start at about 13 years of age. Worldwide, annual prevalence of social phobia is estimated to be about 4.5 % while lifetime prevalence is approximately 3.6 %. However, rates are different from country to country.
For example, only 0.53 % of South Koreans suffer from social phobias compared to the the number of people in Russian region Udmurtia, where it has been estimated that almost 45% suffer from social phobias. Rates of social phobia appear to somewhat reduced from ages of 18 to 64, with a marked drop after the age of 65.
Agoraphobia may begin suddenly or gradually, usually between adolescence and mid-thirties. About 2/3 of patients with agoraphobia are women. Epidemiology studies found that rates of agoraphobia are not so much different between countries as those of other types of phobia.
In the U.S. and around the world the prevalence of agoraphobia without panic attacks is about 0.8 %. So it is about of 1.8 million U.S. adults with agoraphobia. But, 40 % of these cases are diagnosed as severe. The rates of agoraphobia accompanied with panic attack are a little bit higher and is about 1.1%. Rates of agoraphobia appear to be stable at ages of 18 to 64. Rates drop off in the elderly.
Specific phobia usually begins in childhood, around the age of seven. According to data, in the U.S. a fear of animals is the most common specific phobia, with dogs, snakes, and bugs at the top of the list.
In the U.S., it is considered that 9 % of adults have specific phobia, with 22 % of diagnosed cases labeled as severe. 15% of children between the ages of 13-18 have specific phobia, however only 0.6 % are considered as severe cases. But the rates are different from country to country and may vary from the bravest 0.2 % in Northern Ireland to approximately 9% of most frightened in the United States.
Women are known to be 2-4 times more likely compared to men in specific phobia development. Rates appear to be increased somewhat from ages 18-64. In elderly the prevalence of specific phobias appears to drop dramatically.

How phobias develop?
The certain cause and mechanism of phobias development is not yet known. There are various theories, but they can be all classified into following 3 categories:
Psychoanalytic theory of phobia development
According to Sigmund Freud pioneering structural theory, phobias may be related with three stages of conscience:
The id is the most primitive and instinctive part of the mind and may be behind primitive emotions such as fear and anxiety. The superego is the selfless higher state of conscience, with value of judgments and the concept of guilt. The ego is known to be rational moderator between the two. A significant part of the ego is to control the impulses of the id.
In accordance to this theory, phobias are caused by anxiety reactions of the id that have been repressed by the ego. So, it can be said that the feared object is not the original subject of the fear.
Learning theory of phobia development
The learning theory contains a set of theories based on doctrines of behaviorism and cognitive theory. Ivan Pavlov who developed the learning theory showed that dogs could be trained to salivate when a bell rung. Since then, numerous theories of human behavior have been developed.
According to this theory, phobias will develop when fear reactions are punished or reinforced. Both punishment and reinforcement can be positive or negative. Positive reinforcement can be exhibition of something which is positive, including a parent rewarding his child for staying away from a snake.
Positive punishment is the presentation of something negative or unfavorable to prevent that behavior from happening again, such as a child being bitten by a snake.
Biological theory of phobia development
This theory is based on neuropsychology, which is a part of psychology that is dedicated to studying the structure and function of the brain.
Neuropsychologists have been researched and identified specific genes that may play an important role in the development of phobias. Although more researches are needed it is known that certain drugs may affect the chemistry of the brain and be helpful in treating phobias. Most of these therapies are proposed to help anxiety relief by increasing the level of a neurotransmitter serotonin.
Who are at most high risks of phobias?
Patients who have a genetic predisposition to anxiety are at higher risk for developing phobias. Age, gender and socioeconomic may be risk factors for certain phobias. E.g. women are at more high risk to have animal phobias. Those with a low socioeconomic status are at higher risk to have social phobias. Men make up the majority of those with dentist and doctor phobias.
Phobias treatment options
Treatment for phobias may include therapeutic techniques such as cognitive behavioral therapy, medications, or a combination of these two.
Cognitive behavioral therapy or shortly CBT is the most commonly used therapeutic option for phobias. CBT includes exposure to the primary source of the fear in a controlled setting. This treatment can decondition people and reduce anxiety.
The treatment is based on identifying and changing negative thoughts, wrong beliefs, and negative reactions to fear. New CBT techniques use virtual reality technology to safely expose people to the sources of their phobias.
Anti-anxiety drugs and antidepressants can help calm both emotional and physical reactions to fear. Often, the combination of medication and professional therapy makes the biggest difference. If you have a phobia, it’s critical that you seek treatment. Overcoming phobias can be difficult, but there’s hope. With the right treatment, you can learn to manage your fears and lead a productive, fulfilling life.
