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.

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

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).

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.

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.

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.

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.

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.

Though some fears are inborn, the majority are learned. Phobias develop through negative experiences and through observation. One way children begin to develop fears is by witnessing or hearing about dangers. Ollendick proposes while some phobias may originate from a single traumatizing experience, others may be caused by simpler, or less dramatic, origins such as observing another child’s phobic reaction or through the exposure to media that introduces phobias.

- 2% of parents linked their child’s phobia to a [direct conditioning episode]

- 26% of parents linked their child’s phobia to a [vicarious conditioning episodes]

- 56% of parents linked their child’s phobia to their child’s very first contact with water

- 16% of parents could not directly link their child’s phobia

In addition to asking about the origins of a child’s fear, the questionnaire asked if parents believed that “information associated with adverse consequences was the most influential factor in the development of their child’s phobia.” The results were as followed:

- 0% of parents though it was the most influential factor

- 14% of parents though it was somewhat influential

- 86% of parents though it had little to no influence

Phobias are a common form of anxiety disorders and distributions are heterogeneous by age and gender. An American study by the National Institute of Mental Health (NIMH) found that between 8.7 percent and 18.1 percent of Americans suffer from phobias, making it the most common mental illness among women in all age groups and the second most common illness among men older than 25. Between 4 percent and 10 percent of all children experience specific phobias during their lives, and social phobias occur in one percent to three percent of children and adolescents.

A Swedish study found that females have a higher incidence than males (26.5 percent for females and 12.4 percent for males). Among adults, 21.2 percent of women and 10.9 percent of men have a single specific phobia, while multiple phobias occur in 5.4 percent of females and 1.5 percent of males. Women are nearly four times as likely as men to have a fear of animals (12.1 percent in women and 3.3 percent in men) — a higher dimorphic than with all specific or generalized phobias or social phobias. Social phobias are more common in girls than in boys, while situational phobia occurs in 17.4 percent of women and 8.5 percent of men.

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.

There are also many options for treatment of Ablutophobia. Generally seeking professional help from a person with a background in psychology is the best option. A sufferer of Ablutophobia can also undergo Exposure-Based Cognitive Behavioral Therapy in which the person is allowed to confront the feared object (in this case, water) in controlled situations.

There are anxiety medications that medical professionals can prescribe as well, however these medications have yet to show much promise in the treatments of specific phobias such as Ablutophobia. The use of d-cycloserine (DCS) in conjunction with Exposure therapy is the only drug to show developments in alleviating the phobia-related symptoms even after a 3-month period.

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.

As with most phobias this fear could be cured with therapy. Relaxation techniques or support groups could also be effective.

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.

This method was developed in 1979 by interpreting the files of patients diagnosed with claustrophobia and by reading various scientific articles about the diagnosis of the disorder. Once an initial scale was developed, it was tested and sharpened by several experts in the field. Today, it consists of 20 questions that determine anxiety levels and desire to avoid certain situations. Several studies have proved this scale to be effective in claustrophobia diagnosis.

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

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.

This method was developed by Rachman and Taylor, two experts in the field, in 1993. This method is effective in distinguishing symptoms stemming from fear of suffocation and fear of restriction. In 2001, it was modified from 36 to 24 items by another group of field experts. This study has also been proven very effective by various studies.

Although most commonly done with the help of a therapist in a professional setting, exposure to dogs is also possible as a self-help treatment. First, the patient is advised to enlist the help of an assistant who can help set-up the exposure environment, assist in handling the dog during sessions, and demonstrate modeling behaviors. This should also be someone whom the patient trusts and who has no fear of dogs. Then, the patient compiles a hierarchy of fear provoking situations based on their rating of each situation. For example, on a scale from 0 to 100, a patient may feel that looking at photos of dogs may cause a fear response of only 50, however, petting a dog's head may cause of fear response of 100. This list of situations looking at dog photos) to most fearful (petting a dog's head) and the assistant helps the patient to identify common elements that contribute to the fear (i.e., size of the dog, color, how it moves, noise, whether or not it is restrained, etc.). Next, the assistant helps the patient recreate the least fearful situation in a safe, controlled environment, continuing until the patient has had an opportunity to allow the fear to subside thus reinforcing the realization that the fear is unfounded. Once a situation has been mastered, the next fearful situation is recreated and the process is repeated until all the situations in the hierarchy have been experienced.

Sample videos showing humans and dogs interacting without either exhibiting significant fear are available.

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.

Many treatment options are available for those suffering from it. Cognitive behavioral therapy is one form of therapy for people who suffer from certain phobias. It focuses on one's fears and the reason they exist. It tries to change and challenge the thought processes behind one's fear. Studies have shown that it has been effective in treating people with equinophobia. Another treatment option is systematic desensitization, which focuses on gradually acclimating patients to their phobias. The first step in this process may involve thinking about horses, followed by looking at pictures of horses. Once the patient is comfortable with the images, they may proceed to meeting a horse, touching a horse, and finally riding a horse. For extreme cases, it may also be necessary to use medication, even though its effects are only short term.

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

A problem with culture-bound syndromes is that they are resistant to Western-style medicine.} The standard Japanese treatment for taijin kyofusho is Morita therapy, developed by Shoma Morita in the 1910s as a treatment for the Japanese mental disorders taijin kyofusho and shinkeishitsu (nervousness). The original regimen involved patient isolation, enforced bed rest, diary writing, manual labor, and lectures on the importance of self-acceptance and positive endeavor. Since the 1930s, the treatment has been modified to include out-patient and group treatments. This modified version is known as neo-Morita therapy. Medications have also gained acceptance as a treatment option for taijin kyofusho. Other treatments include systematic desensitization, which includes slowly exposing one self to the fear, and learning relaxation skills, to extinguish fear and anxiety.

Milnacipran, a serotonin–norepinephrine reuptake inhibitor (SNRI), is currently used in the treatment of taijin kyofusho and has been shown to be efficacious for the related social anxiety disorder. The primary aspect of treating this disorder is getting patients to focus their attention on their body parts and sensations.
