Main features of diagnostic criteria for specific phobia in the DSM-IV-TR:

- Marked and persistent fear that is excessive or unreasonable, cued by the presence or anticipation of a specific object or situation (e.g., flying, heights, animals, receiving an injection, seeing blood).

- Exposure to the phobic stimulus almost invariably provokes an immediate anxiety response, which may take the form of a situationally bound or situationally predisposed panic attack. In children, the anxiety may be expressed by crying, tantrums, freezing, or clinging.

- The person recognizes that the fear is excessive or unreasonable. In children, this feature may be absent.

- The phobic situation(s) is avoided or else is endured with intense anxiety or distress.

Specific Phobia – DSM 5 Criteria

- Fear or anxiety about a specific object or situation (In children fear/anxiety can be expressed by crying, tantrums, freezing, or clinging)

- The phobic object or situation almost always provokes immediate fear or anxiety

- The phobic object or situation is avoided or endured with intense fear or anxiety

- The fear or anxiety is out of proportion to the actual danger posed by the specific object or situation and to the sociocultural context

- The fear, anxiety, or avoidance is persistent, typically lasting for 6 months or more

- The fear, anxiety, or avoidance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning

- The disturbance is not better explained by symptoms of another mental disorder, including fear, anxiety, and avoidance of situations associated with panic-like symptoms or other incapacitating symptoms; objects or situations related to obsessions; reminders of traumatic events; separation from home or attachment figures; or social situations

According to the fourth revision of the "Diagnostic and Statistical Manual of Mental Disorders", phobias can be classified under the following general categories:

- Animal type – Fear of dogs, cats, rats and/or mice, pigs, cows, birds, spiders, or snakes.

- Natural environment type – Fear of water (aquaphobia), heights (acrophobia), lightning and thunderstorms (astraphobia), or aging (gerascophobia).

- Situational type – Fear of small confined spaces (claustrophobia), or the dark (nyctophobia).

- Blood/injection/injury type – this includes fear of medical procedures, including needles and injections (trypanophobia), fear of blood (hemophobia) and fear of getting injured.

- Other – children's fears of loud sounds or costumed characters.

The terms "distress" and "impairment" as defined by the "Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition" (DSM-IV-TR) should also take into account the context of the person's environment if attempting a diagnosis. The DSM-IV-TR states that if a feared stimulus, whether it be an object or a social situation, is absent entirely in an environment, a diagnosis cannot be made. An example of this situation would be an individual who has a fear of mice but lives in an area devoid of mice. Even though the concept of mice causes marked distress and impairment within the individual, because the individual does not usually encounter mice, no actual distress or impairment is ever experienced. Proximity to, and ability to escape from, the stimulus should also be considered. As the phobic person approaches a feared stimulus, anxiety levels increase, and the degree to which the person perceives they might escape from the stimulus affects the intensity of fear in instances such as riding an elevator (e.g. anxiety increases at the midway point between floors and decreases when the floor is reached and the doors open).

There are various methods used to treat phobias. These methods include systematic desensitization, progressive relaxation, virtual reality, modeling, medication and hypnotherapy.

ICD-10 defines social phobia as a fear of scrutiny by other people leading to avoidance of social situations. The anxiety symptoms may present as a complaint of blushing, hand tremor, nausea or urgency of micturition. Symptoms may progress to panic attacks.

Standardized rating scales such as the Social Phobia Inventory, the SPAI-B, Liebowitz Social Anxiety Scale, and the Social Interaction Anxiety Scale can be used to screen for social anxiety disorder and measure the severity of anxiety.

There are two assessment tools used to diagnose emetophobia; the Specific Phobia of Vomiting inventory and the Emetophobia Questionnaire. The Specific Phobia of Vomiting Inventory and the Emetophobia Questionnaire are both self-report questionnaires that focus on a different range of symptoms.

There have been a limited number of studies in regard to emetophobia. Victims of the phobia usually experience fear before vomiting, but feel less afterwards. The fear comes again however, if the victim fears they will throw up again.

The most common treatment for serious cases is behavior therapy—specifically, systematic desensitization.

Several other self-help treatments exist, mainly involving exposure therapy and relaxation techniques while driving. Additional driving training and practice with a certified teacher also help many to become more confident and less likely to suffer from anxiety.

One of the emerging methods of treating this fear is through the use of virtual therapy.

With repeated exposure, all of the subjects displayed significantly less variance from normal in heart rate acceleration, depression readings, subjective distress, and post-traumatic stress disorder ratings.

Prevention of anxiety disorders is one focus of research. Use of CBT and related techniques may decrease the number of children with social anxiety disorder following completion of prevention programs.

Cognitive behavioral therapy (CBT) is commonly used to treat social phobia.

Phobias of this sort can usually be treated by different types of therapies, including: cognitive behavioral therapy (CBT), psychotherapy, behavior therapy and exposure therapy.

Practice may play an important part in overcoming fear. It may be helpful to sufferers to increase phone usage at a slow pace, starting with simple calls and gradually working their way up. For example, they may find it easier to start with automated calls, move on to conversations with family and friends, and then further extend both the length of conversations and the range of people with whom conversations are held.

Treatment of social phobia usually involves psychotherapy, medication, or both.

There are several options for treatment of scopophobia. With one option, desensitization, the patient is stared at for a prolonged period and then describes their feelings. The hope is that the individual will either be desensitized to being stared at or will discover the root of their scopophobia.

Exposure therapy, another treatment commonly prescribed, has five steps:

- Evaluation

- Feedback

- Developing a fear hierarchy

- Exposure

- Building

In the evaluation stage, the scopophobic individual would describe their fear to the therapist and try to find out when and why this fear developed. The feedback stage is when the therapist offers a way of treating the phobia. A fear hierarchy is then developed, where the individual creates a list of scenarios involving their fear, with each one becoming worse and worse. Exposure involves the individual being exposed to the scenarios and situations in their fear hierarchy. Finally, building is when the patient, comfortable with one step, moves on to the next.

As with many human health problems support groups exist for scopophobic individuals. Being around other people who face the same issues can often create a more comfortable environment.

Other suggested treatments for scopophobia include hypnotherapy, neuro-linguistic programming (NLP), and energy psychology. In extreme cases of scopophobia, it is possible for the subject to be prescribed anti–anxiety medications. Medications may include benzodiazepines, antidepressants, or beta-blockers.

The most common methods for the treatment of specific phobias are systematic desensitization and in vivo or exposure therapy.

There are many ways to treat phobophobia, and the methods used to treat panic disorders have been shown to be effective to treat phobophobia, because panic disorder patients will present in a similar fashion to conventional phobics and perceive their fear as totally irrational. Also, exposure based techniques have formed the basis of the armamentarium of behaviour therapists in the treatment of phobic disorders for many years, they are the most effective forms of treatment for phobic avoidance behavior. Phobics are treated by exposing them to the stimuli which they specially fear, and in case of phobophobia, it is both the phobia they fear and their own sensations. There are two ways to approach interoceptive exposure on patients:

- Paradoxical intention: This method is especially useful to treat the fear towards the phobophobia and the phobia they fear, as well as some of the sensations the patient fears. This method exposes the patient to the stimuli that causes the fear, which they avoid. The patient is directly exposed to it bringing them to experience the sensations that they fear, as well as the phobia. This exposure based technique helps the doctor by guiding the patient to encounter their fears and overcome them by feeling no danger around them.

- Symptoms artificially produced: This method is very useful to treat the fear towards the sensations encountered when experiencing phobophobia, the main feared stimuli of this anxiety disorder. By ingestion of different chemical agents, such as caffeine, CO-O or adrenalin, some of the symptoms the patient feels when encountering phobophobia and other anxiety disorders are triggered, such as hyperventilation, heart pounding, blurring of vision and paresthesia, which can lead to the controlling of the sensations by the patients. At first, panic attacks will be encountered, but eventually, as the study made by Doctor Griez and Van den Hout shows, the patient shows no fear to somatic sensations and panic attacks and eventually of the phobia feared.

Cognitive modification is another method that helps considerably to treat phobophobics. When treating the patients with the method, doctors correct some wrong information the patient might have about his disease, such as their catastrophic beliefs or imminent disaster by the feared phobia. Some doctors have even agreed that this is the most helpful component, since it has shown to be very effective especially if combined with other methods, like interoceptive exposure. The doctor seeks to convince patients that their symptoms do not signify danger or loss of control, for example, if combined with the interoceptive exposure, the doctor can show them that there is no unavoidable calamity and if the patient can keep themselves under control, they learn by themselves that there is no real threat and that it is just in their mind. Cognitive modification also seeks to correct other minor misconceptions, such as the belief that the individual will go crazy and may need to be "locked away forever" or that they will totally lose control and perhaps "run amok". Probably, the most difficult aspect of cognitive restructuring for the majority of the patients will simply be to identify their aberrant beliefs and approach them realistically.

Relaxation and breathing control techniques are used to produce the symptoms naturally. The somatic sensations, the feared stimuli of phobophobia, are sought to be controlled by the patient to reduce the effects of phobophobia. One of the major symptoms encountered is that of hyperventilation, which produce dizziness, faintness, etc. So, hyperventilation is induced in the patients in order to increase their CO levels that produce some of this symptoms. By teaching the patients to control this sensations by relaxing and controlling the way they breathe, this symptoms can be avoided and reduce phobophobia. This method is useful if combined with other methods, because alone it doesn't treat other main problems of phobophobia.

Patients are typically sent to therapy for BII phobia in order to receive therapeutic treatments to calm their levels of anxiety and stress. Therapists use a combination of psychological and physical measures, such as applying muscle tension, in order to help the patient to be aware that there is certainly a needle in front of them.

A popular method of treatment for BII phobics is Cognitive-Behavior Therapy (CBT), which is a technique that allows the patient to become immune to their fear by being exposed to it. For BII phobics, patients are given pictures of needles or blood, they are also asked to draw pictures of these needles and speak about it. Afterwards, they are given an actual needle, and the goal is: by that point, that the patient is to be comfortable enough with their fear of needles and blood.

Some patients may refuse professional help for their phobia. Instead, a different type of treatment solely revolves around motivation and whether or not the patient is willing to undergo through treating their phobia with self-help. Similar to CBT, patients treat themselves by completing exercises to become immune to their fear. This requires no professional assistance and merely relies on the person.

Research on hypnotherapy has been looked upon to treat patients with BII phobia. Hypnotherapists are known for using relaxing therapies towards individuals with common anxiety issues. A form of therapy given to patients with BII phobia include the “Applied Tension” method, which was developed by Lars-Göran Öst and his colleagues at the University of Uppsala in Sweden. This “coping method involves creating tension on a person’s arms, legs, and chest until they start to feel their body temperature rising,” (Robertson) which usually occurs within 10 to 20 seconds. These sessions of muscle tension is repeated 5 times with 20 to 30 second breaks. Patients should complete this form of therapy over the course of 5 weeks. This helps to prevent the patient from fainting by applying tension to the body, the blood pressure steadily rises, preventing any sudden drop until their vaccination is complete. By using this treatment, there was a noticeable improvement by 90% of patients with BII phobia. Compared to patients that only used the relaxation methods, where only 60% showed noticeable improvement.

Along with muscle tension,there are several methods of physical maneuvers that can help with the treatment of BII phobia. Therapists suggest that while being injected, patients should perform movements, such as: leg crossing, muscle tensing, and holding in the breath. Patients are instructed by their therapist to perform these maneuvers simultaneously while being injected with a needle. It’s also recommended that the patient stays seated with their head lowered while performing these movements.

Whether utilizing systematic desensitization therapy or exposure therapy, several factors will determine how many sessions will be required to completely remove the phobia; however, some studies (such as a follow-up study done by Dr. Öst in 1996) have shown that those who overcome their phobia are usually able to maintain the improvement over the long-term. As avoidance contributes to the perpetuation of the phobia, constant, yet safe, real world interaction is recommended during and after therapy in order to reinforce positive exposure to the animal.

Phobophobia is the fear of phobia(s) and, more specifically, of the internal sensations associated with that phobia and anxiety, which binds it closely to other anxiety disorders, especially with generalized anxiety disorders (free floating fears) and panic attacks. It is a condition in which anxiety disorders are maintained in an extended way, which combined with the psychological fear generated by phobophobia of encountering the feared phobia would ultimately lead to the intensifying of the effects of the feared phobia that the patient might have developed, such as agoraphobia, and specially with it, and making them susceptible to having an extreme fear of panicking. Phobophobia comes in between the stress the patient might be experiencing and the phobia that the patient has developed as well as the effects on his life, or in other words, it is a bridge between anxiety/panic the patient might be experiencing and the type of phobia he/she fears, creating an intense and extreme predisposition to the feared phobia. Nevertheless, phobophobia is not necessarily developed as part of other phobias, but can be an important factor for maintaining them.

Phobophobia differentiates itself from other kind of phobias by the fact that there is no environmental stimulus per se, but rather internal dreadful sensations similar to psychological symptoms of panic attacks. The psychological state of the mind creates an anxious response that has itself a conditioned stimuli leading to further anxiety, resulting in a vicious cycle. Phobophobia is a fear experienced before actually experiencing the fear of the feared phobias its somatic sensations that precede it, which is preceded by generalized anxiety disorders and can generate panic attacks. Like all the phobias, the patients avoids the feared phobia in order to avoid the fear of it.

Coping strategies may consist of planning the conversation ahead of time and rehearsing, writing or noting down what needs to be said. This may be helped by having privacy in which to make a call.

Associated avoidance behavior may include asking others (e.g. relatives at home) to take phone calls and exclusively using answering machines. The rise in the use of electronic text-based communication (the Internet, email and text messaging) has given many sufferers alternative means of communication that they tend to find considerably less stressful than the phone. However, some individuals experience "textphobia", a fear or anxiety of texting or messaging, and also avoid those forms of communication.

Sufferers may find it helpful to explain the nature of the phobia to friends, so that a failure to respond to messages is not misinterpreted as rudeness or an unwillingness to communicate.

According to Child and Adolescent Mental Health, approximately 5 percent of children suffer from specific phobias and 15 percent seek treatment for anxiety-related problems. In recent years the number of children with clinically diagnosed phobias has gradually increased. Researchers are finding that the majority of these diagnoses come anxiety related phobias or society phobias.

Specific phobias are more prevalent in girls than in boys. Likewise, specific phobias are also more prevalent in older children than younger.

Also noted in the emetophobia internet survey was information about medications. People were asked whether they would consider taking anxiety medication to potentially help their fear, and many in the study answered they wouldn't for fear that the drugs would make them nauseated. Others, however, stated that some psychotropic medications (such as benzodiazepines and antidepressants) did help with their phobia, and some said gastrointestinal medications were also beneficial.

The most widely used and possibly the most effective treatment for astraphobia is exposure to thunderstorms and eventually building an immunity. Cognitive behavioral therapy is also often used to treat astraphobia. The patient will in many cases be instructed to repeat phrases to himself or herself in order to become calm during a storm. Heavy breathing exercises can reinforce this effort.

BII phobia is one of the more common psychiatric disorders, affecting about 3 to 4% of the general population, and in about 80% of the BII phobia cases, the patient experiences syncope or presyncope. After a random survey was completed in Aligarh, India, with 1648 male and 1613 female, it was found that a significantly higher percentage of females compared to males had BII phobia; 23.36% of females were diagnosed with BII phobia while only 11.19% of males were diagnosed. Females also fainted more often than males, at 64.09% compared to a male rate of 39.4%.

Furthermore, only 5.3% of BII phobia patients reported to have visited the hospital once or twice for consultation about BII phobia, however, without engaging in any kind of treatment.

Another study, involving participants from all 50 states and the District of Columbia, ages 65 years and older, found that a total of 386 participants disclosed having BII Phobia throughout their whole lifetime, 90% of those cases consisted of patients dealing with BII Phobia as well as other lifetime fears.

The fear of spiders can be treated by any of the general techniques suggested for specific phobias. The first line of treatment is systematic desensitization – also known as exposure therapy – which was first described by South African psychiatrist Joseph Wolpe. Before engaging in systematic desensitization it is common to train the individual with arachnophobia in relaxation techniques, which will help keep the patient calm. Systematic desensitization can be done in vivo (with live spiders) or by getting the individual to imagine situations involving spiders, then modelling interaction with spiders for the person affected and eventually interacting with real spiders. This technique can be effective in just one session.

Recent advances in technology have enabled the use of virtual or augmented reality spiders for use in therapy. These techniques have proven to be effective.

Driving phobia, also called vehophobia or a fear of driving, can be severe enough to be considered an intense, persistent fear or phobia. It is often great enough that people will avoid driving at all costs, and instead find someone to drive them or use public transportation, regardless of how inconvenient or expensive.

A fear of driving may escalate to a phobia during difficult driving situations, such as freeway driving or congested traffic.

Autophobia is a form of anxiety that can cause a minor to extreme feeling of danger or fear when alone. There is not a specific treatment to cure autophobia as it affects each person differently. Most sufferers are treated with psychotherapy in which the amount of time that they are alone is slowly increased. There are no conclusive studies currently that support any medications being used as treatment. If the anxiety is too intense medications have been used to aid the patient in a continuation of the therapy.

It is not uncommon for sufferers to be unaware that they have this anxiety and to dismiss the idea of seeking help. Much like substance abuse, autophobia is mental and physical and requires assistance from a medical professional. Medication can be used to stabilize symptoms and inhibit further substance abuse. Group and individual therapy is used to help ease symptoms and treat the phobia.

In mild cases of autophobia, treatment can sometimes be very simple. Therapists recommend many different remedies to make patients feel as though they are not alone even when that is the case, such as listening to music when running errands alone or turning on the television when at home, even if it is just for background noise. Using noise to interrupt the silence of isolated situations can often be a great help for people suffering from autophobia.

However, it is important to remember that just because a person may feel alone at times does not mean that they have autophobia. Most people feel alone and secluded at times; this is not an unusual phenomenon. Only when the fear of being alone beings to interrupt how a person lives their daily life does the idea of being autophobic become a possibility.
