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).

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.

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

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.

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

Fear of intimacy is generally a social phobia and anxiety disorder resulting in difficulty forming close relationships with another person. The term can also refer to a scale on a psychometric test, or a type of adult in attachment theory psychology.

The fear of intimacy is the fear of being emotionally and/or physically close to another individual. This fear is also defined as “the inhibited capacity of an individual, because of anxiety, to exchange thought and feelings of personal significance with another individual who is highly valued”. Fear of intimacy is the expression of existential views in that to love and to be loved makes life seem precious and death more inevitable. It often results from past traumas such as rape or childhood sexual abuse. Fear of intimacy is also related to the fear of being touched .

There is no universal cure for genophobia. Some ways of coping with or treating anxiety issues is to see a psychiatrist, psychologist, or licensed counselor for therapy. Some people experiencing pain during sex may visit their doctor or gynecologist. Medicine may also be prescribed to treat the anxiety brought on by the phobia.

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.

There can be many different reasons for why people develop genophobia. Some of the main causes are former incidents of sexual assaults or abuse. These incidents violate the victim’s trust and take away their sense of right to self-determination. Another possible cause of genophobia is the feeling of intense shame or medical reasons. Others may have the fear without any diagnosable reason.

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.

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.

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.

Ergophobia or ergasiophobia is an abnormal and persistent fear of (manual labor, non-manual labour, etc.) or finding employment. Ergophobia may also be a subset of either social phobia or performance anxiety. Sufferers of ergophobia experience undue anxiety about the workplace environment even though they realize their fear is irrational. Their fear may actually be a combination of fears, such as fear of failing at assigned tasks, speaking before groups at work (both of which are types of performance anxiety), socializing with co-workers (a type of social phobia), and other fears of emotional, psychological and/or physiological injuries.

The term "ergophobia" comes from the Greek "ergon" (work) and "phobos" (fear).

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.

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.

People with this fear are anxious about or afraid of intimate relationships. They believe that they do not deserve love or support from others. Fear of intimacy has three defining features: content which represents the ability to communicate personal information, emotional valence which refers to the feelings about personal information exchanged, and vulnerability signifying their regard for the person they are intimate with. Bartholomew and Horowitz go further and determine four different adult attachment types: “(1) Secure individuals have a sense of worthiness or lovability and are comfortable with intimacy and autonomy; (2) preoccupied persons lack this sense of self-worthiness yet view others positively and seek their love and acceptance; (3) fearful people lack a sense of lovability and are avoidant of others in anticipation of rejection; (4) dismissing persons feel worthy of love yet detach from others whom they generally regard as untrustworthy”.

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.

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

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

Autophobia, also called monophobia, isolophobia, or eremophobia, is the specific phobia of isolation; a morbid fear of being egotistical, or a dread of being alone or isolated. Sufferers need not be physically alone, but just to believe that they are being ignored or unloved. Contrary to what would be implied by a literal reading of the term, "autophobia" does not describe a "fear of oneself". The disorder typically develops from and is associated with other anxiety disorders.

Autophobia can be associated with or accompanied by several other phobias such as agoraphobia, and is generally considered to be a part of the agoraphobic cluster. This means that autophobia has a lot of the same characteristics as certain anxiety disorders and hyperventilation disorders. The main concern of people with phobias in the agoraphobic cluster is getting help in case of emergency. This means people might be afraid of going out in public, being caught in a crowd, being alone, or being stranded.

Autophobia is not to be confused with agoraphobia (fear of being in public, or caught in large crowds), self-hatred, or social anxiety although it can be closely related to these things. It is its own phobia that tends to be accompanied by other anxiety disorders and phobias.

Scopophobia is unique among phobias in that the fear of being looked at is considered both a social phobia and a specific phobia, because it is a specific occurrence which takes place in a social setting. Most phobias typically fall in either one category or the other but scopophobia can be placed in both. On the other hand, as with most phobias, scopophobia generally arises from a traumatic event in the person's life. With scopophobia, it is likely that the person was subjected to public ridicule as a child. Additionally, a person suffering from scopophobia may often be the subject to public staring, possibly due to a deformity or physical ailment.

According to the Social Phobia/Social Anxiety Association, U.S. government data for 2012 suggests that social anxiety affects over 7% of the population at any given time. Stretched over a lifetime, the percentage increases to 13%.

Discriminatory aspects of ageism have been strongly linked to gerontophobia. This irrational fear or hatred of the elderly is associated with the fact that someday all young people will grow old and that old age is associated with death. This unwillingness to accept death manifests in feelings of hostility and discriminatory acts towards the elderly.
