There are many ways a person may go about receiving therapy for ego-dystonic sexual orientation associated with homosexuality. There is no known therapy for other types of ego-dystonic sexual orientations. Therapy can be aimed at changing sexual orientation, sexual behaviour, or helping a client become more comfortable with their sexual orientation and behaviours. Human rights groups have accused some countries of performing these treatments on egosyntonic homosexuals. One survey suggested that viewing the same-sex activities as compulsive facilitated commitment to a mixed-orientation marriage and to monogamy. Treatment may include sexual orientation change efforts or treatment to alleviate the stress. In addition, some people seek non-professional methods, such as religious counselling or attendance in an ex-gay group.

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.

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.

Electroconvulsive therapy (ECT) is sometimes used in severe cases when other interventions for severe intractable depression have failed. Psychosurgery is considered experimental but is advocated by some neurologists in certain rare cases.

Counseling (professional) and co-counseling (between peers) may be used. Psychoeducation programs may provide people with the information to understand and manage their problems. Creative therapies are sometimes used, including music therapy, art therapy or drama therapy. Lifestyle adjustments and supportive measures are often used, including peer support, self-help groups for mental health and supported housing or supported employment (including social firms). Some advocate dietary supplements.

Reasonable accommodations (adjustments and supports) might be put in place to help an individual cope and succeed in environments despite potential disability related to mental health problems. This could include an emotional support animal or specifically trained psychiatric service dog.

A major option for many mental disorders is psychiatric medication and there are several main groups. Antidepressants are used for the treatment of clinical depression, as well as often for anxiety and a range of other disorders. Anxiolytics (including sedatives) are used for anxiety disorders and related problems such as insomnia. Mood stabilizers are used primarily in bipolar disorder. Antipsychotics are used for psychotic disorders, notably for positive symptoms in schizophrenia, and also increasingly for a range of other disorders. Stimulants are commonly used, notably for ADHD.

Despite the different conventional names of the drug groups, there may be considerable overlap in the disorders for which they are actually indicated, and there may also be off-label use of medications. There can be problems with adverse effects of medication and adherence to them, and there is also criticism of pharmaceutical marketing and professional conflicts of interest.

ASPD is considered to be among the most difficult personality disorders to treat. Because of their very low or absent capacity for remorse, individuals with ASPD often lack sufficient motivation and fail to see the costs associated with antisocial acts. They may only simulate remorse rather than truly commit to change: they can be seductively charming and dishonest, and may manipulate staff and fellow patients during treatment. Studies have shown that outpatient therapy is not likely to be successful, but the extent to which persons with ASPD are entirely unresponsive to treatment may have been exaggerated.

Those with ASPD may stay in treatment only as required by an external source, such as parole conditions. Residential programs that provide a carefully controlled environment of structure and supervision along with peer confrontation have been recommended. There has been some research on the treatment of ASPD that indicated positive results for therapeutic interventions.

Psychotherapy also known as talk therapy is found to help treat patients with ASPD.Schema therapy is also being investigated as a treatment for ASPD. A review by Charles M. Borduin features the strong influence of Multisystemic therapy (MST) that could potentially improve this imperative issue. However, this treatment requires complete cooperation and participation of all family members. Some studies have found that the presence of ASPD does not significantly interfere with treatment for other disorders, such as substance abuse, although others have reported contradictory findings.

Therapists working with individuals with ASPD may have considerable negative feelings toward patients with extensive histories of aggressive, exploitative, and abusive behaviors. Rather than attempt to develop a sense of conscience in these individuals, which is extremely difficult considering the nature of the disorder, therapeutic techniques are focused on rational and utilitarian arguments against repeating past mistakes. These approaches would focus on the tangible, material value of prosocial behavior and abstaining from antisocial behavior. However, the impulsive and aggressive nature of those with this disorder may limit the effectiveness of even this form of therapy.

The use of medications in treating antisocial personality disorder is still poorly explored, and no medications have been approved by the FDA to specifically treat ASPD. A 2010 Cochrane review of studies that explored the use of pharmaceuticals in ASPD patients, of which 8 studies met the selection criteria for review, concluded that the current body of evidence was inconclusive for recommendations concerning the use of pharmaceuticals in treating the various issues of ASPD. Nonetheless psychiatric medications such as antipsychotics, antidepressants, and mood stabilizers can be used to control symptoms such as aggression and impulsivity, as well as treat disorders that may co-occur with ASPD for which medications are indicated.

Antidepressant medications most commonly used to treat anxiety disorders are mainly selective serotonin reuptake inhibitors. Benzodiazepines, monoamine oxidase inhibitor, and tricyclic antidepressants are also sometimes prescribed for treatment of agoraphobia. Antidepressants are important because some have antipanic effects. Antidepressants should be used in conjunction with exposure as a form of self-help or with cognitive behaviour therapy. A combination of medication and cognitive behaviour therapy is sometimes the most effective treatment for agoraphobia.

Benzodiazepines, antianxiety medications such as alprazolam and clonazepam, are used to treat anxiety and can also help control the symptoms of a panic attack. If taken in doses larger than those prescribed, or for too long, they can cause dependence. Side effects may include confusion, drowsiness, light-headedness, loss of balance, and memory loss.

Treatment for perfectionism can be approached from many therapeutic directions. Some examples of psychotherapy include: cognitive-behavioral therapy (the challenging of irrational thoughts and formation of alternative ways of coping and thinking), psychoanalytic therapy (an analysis of underlying motives and issues), group therapy (where two or more clients work with one or more therapists about a specific issue, this is beneficial for those who feel as if they are the only one experiencing a certain problem), humanistic therapy (person-centered therapy where the positive aspects are highlighted), and self-therapy (personal time for the person where journaling, self-discipline, self-monitoring, and honesty with self are essential). Cognitive-behavioral therapy has been shown to successfully help perfectionists in reducing social anxiety, public self-consciousness, and perfectionism. By using this approach, a person can begin to recognize his or her irrational thinking and find an alternative way to approach situations. Cognitive-behavioral therapy is intended to help the person understand that it is okay to make mistakes sometimes and that those mistakes can become lessons learned.

The APA has roundly dismissed so-called conversion therapy (sometimes called "ex-gay" therapy) as unproductive and potentially harmful.

One version of conversion therapy, Gender Wholeness Therapy was designed by an ex-gay Licensed Professional Counselor, David Matheson. "The emphasis in Mr. Matheson's counselling is on helping men — all his clients are male — develop 'gender wholeness' by addressing emotional issues and building healthy connections with other men. He says he believes that helps reduce homosexual desires.

Another variation of conversion therapy, "gender-affirmative therapy" has been described by A. Dean Byrd as follows: "The basic premise of gender-affirmative therapy is that social and emotional variables affect gender identity which, in turn, determines sexual orientation. The work of the therapist is to help people understand their gender development. Subsequently, such individuals are able to make choices that are consistent with their value system. The focus of therapy is to help clients fully develop their masculine or feminine identity".

Several organizations have started retreats led by coaches aimed at helping participants diminish same-sex desires. These retreats tend to use a variety of techniques. Journey into Manhood, put on by People Can Change, uses "a wide variety of large-group, small-group and individual exercises, from journaling to visualizations (or guided imagery) to group sharing and intensive emotional-release work." Weekends put on by Adventure in Manhood support "healthy bonding with men, through masculine activity, teamwork, and socialization." Though not specific to gay men, several gay men attended the New Warrior Training Adventure, a weekend put on by ManKind Project, which is a "process of initiation and self-examination that is designed to catalyse the development of a healthy and mature masculine self." Joe Dallas, a prominent ex-gay, leads a monthly five-day men's retreat on sexual purity titled, Every Man's Battle.

Several reparative therapies have been established, including:

- Sexual identity therapy was designed by Warren Throckmorton and Mark Yarhouse, and was endorsed by Robert L. Spitzer, prior to Spitzer's backing away from this belief that he had proven reparative therapy at times successful. Its purpose is to help patients line up their sexual identity with their beliefs and values. Therapy involves four phases: (1) assessment, (2) advanced or expanded informed consent, (3) psychotherapy, and (4) social integration of a valued sexual identity.

- Group psychotherapy uses group sessions led by a single psychologist and focuses on conflict surrounding homosexual expression.

- Context Specific Therapy was designed by Jeffrey Robinson. It does not work with any one theory of homosexuality, but uses several theoretical backgrounds according to the client's need, and is based on phenomenological research. It does not seek to change the client's orientation, but instead focuses on diminishing homosexual thoughts and behaviours. It works within the client's own view of God, noting that "individuals who are successful at overcoming homosexual problems are motivated by strong religious values".

- MAP Therapy is designed for both the individual with ego-dystonic sexual orientation and their family members. There are four main paths that clients may choose to take: (1) they can affirm an LGB identity, (2) they can foster a lifestyle of celibacy, (3) they can work on developing heterosexual attractions, or (4) they can explore their options.

The following are two therapies normally used in treating specific phobia:

Cognitive behavioral therapy (CBT), a short term, skills-focused therapy that aims to help people diffuse unhelpful emotional responses by helping people consider them differently or change their behavior, is effective in treating specific phobias. Exposure therapy is a particularly effective form of CBT for specific phobias. Medications to aid CBT have not been as encouraging with the exception of adjunctive D-clycoserine.

In general anxiolytic medication is not seen as helpful in specific phobia but benzodiazepines are sometimes used to help resolve acute episodes; as 2007 data were sparse for efficacy of any drug.

Another example of treatment besides coding is Functional Ideographic Assessment Template. The functional ideographic assessment template, also known as FIAT, was used as a way to generalize the clinical processes of functional analytic psychotherapy. The template was made by a combined effort of therapists and can be used to represent the behaviors that are a focus for this treatment. Using the FIAT therapists can create a common language to get stable and accurate communication results through functional analytic psychotherapy at the ease of the client; as well as the therapist.

Eye movement desensitization and reprocessing (EMDR) has been studied as a possible treatment for agoraphobia, with poor results. As such, EMDR is only recommended in cases where cognitive-behavioral approaches have proven ineffective or in cases where agoraphobia has developed following trauma.

Many people with anxiety disorders benefit from joining a self-help or support group (telephone conference-call support groups or online support groups being of particular help for completely housebound individuals). Sharing problems and achievements with others, as well as sharing various self-help tools, are common activities in these groups. In particular, stress management techniques and various kinds of meditation practices and visualization techniques can help people with anxiety disorders calm themselves and may enhance the effects of therapy, as can service to others, which can distract from the self-absorption that tends to go with anxiety problems. Also, preliminary evidence suggests aerobic exercise may have a calming effect. Since caffeine, certain illicit drugs, and even some over-the-counter cold medications can aggravate the symptoms of anxiety disorders, they should be avoided.

Other prescription drugs are also used, if other methods are not effective. Before the introduction of SSRIs, monoamine oxidase inhibitors (MAOIs) such as phenelzine were frequently used in the treatment of social anxiety. Evidence continues to indicate that MAOIs are effective in the treatment and management of social anxiety disorder and they are still used, but generally only as a last resort medication, owing to concerns about dietary restrictions, possible adverse drug interactions and a recommendation of multiple doses per day. A newer type of this medication, Reversible inhibitors of monoamine oxidase subtype A (RIMAs) such as the drug moclobemide, bind reversibly to the MAO-A enzyme, greatly reducing the risk of hypertensive crisis with dietary tyramine intake.

Benzodiazepines such as clonazepam are an alternative to SSRIs. These drugs are often used for short-term relief of severe, disabling anxiety. Although benzodiazepines are still sometimes prescribed for long-term everyday use in some countries, there is concern over the development of drug tolerance, dependency and misuse. It has been recommended that benzodiazepines be considered only for individuals who fail to respond to other medications. Benzodiazepines augment the action of GABA, the major inhibitory neurotransmitter in the brain; effects usually begin to appear within minutes or hours. In most patients, tolerance rapidly develops to the sedative effects of benzodiazepines, but not to the anxiolytic effects. Long-term use of benzodiazepine may result in physical dependence, and abrupt discontinuation of the drug should be avoided due to high potential for withdrawal symptoms (including tremor, insomnia, and in rare cases, seizures). A gradual tapering of the dose of clonazepam (a decrease of 0.25 mg every 2 weeks), however, has been shown to be well tolerated by patients with social anxiety disorder. Benzodiazepines are not recommended as monotherapy for patients who have major depression in addition to social anxiety disorder and should be avoided in patients with a history of substance abuse.

Certain anticonvulsant drugs such as gabapentin are effective in social anxiety disorder and may be a possible treatment alternative to benzodiazepines.

Serotonin-norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine have shown similar effectiveness to the SSRIs. In Japan, Milnacipran is used in the treatment of Taijin kyofusho, a Japanese variant of social anxiety disorder. The atypical antidepressants mirtazapine and bupropion have been studied for the treatment of social anxiety disorder, and rendered mixed results.

Some people with a form of social phobia called performance phobia have been helped by beta-blockers, which are more commonly used to control high blood pressure. Taken in low doses, they control the physical manifestation of anxiety and can be taken before a public performance.

A novel treatment approach has recently been developed as a result of translational research. It has been shown that a combination of acute dosing of d-cycloserine (DCS) with exposure therapy facilitates the effects of exposure therapy of social phobia. DCS is an old antibiotic medication used for treating tuberculosis and does not have any anxiolytic properties per se. However, it acts as an agonist at the glutamatergic N-methyl-D-aspartate (NMDA) receptor site, which is important for learning and memory.

Kava-kava has also attracted attention as a possible treatment, although safety concerns exist.

There are a number of different treatments that are available to treat and manage conversion syndrome. Treatments for conversion syndrome include hypnosis, psychotherapy, physical therapy, stress management, and transcranial magnetic stimulation. Treatment plans will consider duration and presentation of symptoms and may include one or multiple of the above treatments. This may include the following:

1. Explanation. This must be clear and coherent as attributing physical symptoms to a psychological cause is not accepted by many educated people in western cultures. It must emphasize the genuineness of the condition, that it is common, potentially reversible and does not mean that the sufferer is psychotic. Taking a neutral-cause-based stance by describing the symptoms as functional may be helpful, but further studies are required. Ideally, the patient should be followed up neurologically for a while to ensure that the diagnosis has been understood.

2. Physiotherapy where appropriate;

3. Occupational Therapy to maintain autonomy in activities of daily living;

4. Treatment of comorbid depression or anxiety if present.

There is little evidence-based treatment of conversion disorder. Other treatments such as cognitive behavioral therapy, hypnosis, EMDR, and psychodynamic psychotherapy, EEG brain biofeedback need further trials. Psychoanalytic treatment may possibly be helpful. However, most studies assessing the efficacy of these treatments are of poor quality and larger, better controlled studies are urgently needed. Cognitive Behavioural Therapy is the most common treatment, however boasts a mere 13% improvement rate.

Another way to treat histrionic personality disorder after identification is through functional analytic psychotherapy. The job of a Functional Analytic Psychotherapist is to identify the interpersonal problems with the patient as they happen in session or out of session. Initial goals of functional analytic psychotherapy are set by the therapist and include behaviors that fit the client's needs for improvement. Functional analytic psychotherapy differs from the traditional psychotherapy due to the fact that the therapist directly addresses the patterns of behavior as they occur in-session.

The in-session behaviors of the patient or client are considered to be examples of their patterns of poor interpersonal communication and to adjust their neurotic defenses. To do this, the therapist must act on the client's behavior as it happens in real time and give feedback on how the client's behavior is affecting their relationship during therapy. The therapist also helps the client with histrionic personality disorder by denoting behaviors that happen outside of treatment; these behaviors are termed "Outside Problems" and "Outside Improvements". This allows the therapist to assist in problems and improvements outside of session and to verbally support the client and condition optimal patterns of behavior". This then can reflect on how they are advancing in-session and outside of session by generalizing their behaviors over time for changes or improvement".

There are many different forms (modalities) of treatment used for personality disorders:

- Individual psychotherapy has been a mainstay of treatment. There are long-term and short-term (brief) forms.

- Family therapy, including couples therapy.

- Group therapy for personality dysfunction is probably the second most used.

- Psychological-education may be used as an addition.

- Self-help groups may provide resources for personality disorders.

- Psychiatric medications for treating symptoms of personality dysfunction or co-occurring conditions.

- Milieu therapy, a kind of group-based residential approach, has a history of use in treating personality disorders, including therapeutic communities.

- The practice of mindfulness that includes developing the ability to be nonjudgmentally aware of unpleasant emotions appears to be a promising clinical tool for managing different types of personality disorders.

There are different specific theories or schools of therapy within many of these modalities. They may, for example, emphasize psychodynamic techniques, or cognitive or behavioral techniques. In clinical practice, many therapists use an 'eclectic' approach, taking elements of different schools as and when they seem to fit to an individual client. There is also often a focus on common themes that seem to be beneficial regardless of techniques, including attributes of the therapist (e.g. trustworthiness, competence, caring), processes afforded to the client (e.g. ability to express and confide difficulties and emotions), and the match between the two (e.g. aiming for mutual respect, trust and boundaries).

In China, traditional treatment based on the causes suggested by cultural beliefs are administrated to the patient. Praying to gods and asking Taoist priests to perform exorcism is common. If a fox spirit is believed to be involved, people may hit gongs or beat the person to drive it out. The person will receive a yang- or yin-augmenting Chinese medicine potion, usually including herbs, pilose antler (stag of deer) or deer tail, and tiger penis, deer penis, or fur seal penis. Other foods for therapy are pepper soup, ginger soup and liquor.

Gynophobia or gynephobia is an abnormal fear of women, a type of specific social phobia. In the past, the Latin term horror feminae was used.

Gynophobia should not be confused with misogyny, the hatred, contempt for and inveterate prejudice against women, although some may use the terms interchangeably, in reference to the social, rather than pathological aspect of negative attitudes towards women.

An antonym is philogyny, the love, respect for and admiration of women.

Treatment is dependent on the underlying cause, whether it is organic or psychological in origin. If depersonalization is a symptom of neurological disease, then diagnosis and treatment of the specific disease is the first approach. Depersonalization can be a cognitive symptom of such diseases as amyotrophic lateral sclerosis, Alzheimer's, multiple sclerosis (MS), neuroborreliosis (Lyme disease), or any other neurological disease affecting the brain. For those suffering from depersonalization with migraine, tricyclic antidepressants are often prescribed.

If depersonalization is a symptom of psychological causes such as developmental trauma, treatment depends on the diagnosis. In case of dissociative identity disorder or DD-NOS as a developmental disorder, in which extreme developmental trauma interferes with formation of a single cohesive identity, treatment requires proper psychotherapy, and—in the case of additional (co-morbid) disorders such as eating disorders—a team of specialists treating such an individual. It can also be a symptom of borderline personality disorder, which can be treated in the long term with proper psychotherapy and psychopharmacology.

The treatment of chronic depersonalization is considered in depersonalization disorder.

A recently completed study at Columbia University in New York City has shown positive effects from transcranial magnetic stimulation (TMS) to treat depersonalization disorder. Currently, however, the FDA has not approved TMS to treat DP.

A 2001 Russian study showed that naloxone, a drug used to reverse the intoxicating effects of opioid drugs, can successfully treat depersonalization disorder. According to the study: "In three of 14 patients, depersonalization symptoms disappeared entirely and seven patients showed a marked improvement. The therapeutic effect of naloxone provides evidence for the role of the endogenous opioid system in the pathogenesis of depersonalization."

Biphobia is aversion toward bisexuality and toward bisexual people as a social group or as individuals. It can take the form of denial that bisexuality is a genuine sexual orientation, or of negative stereotypes about people who are bisexual (such as the beliefs that they are promiscuous or dishonest). People of any sexual orientation can experience or perpetuate biphobia, and it is a source of social discrimination against bisexual people.

Selective serotonin reuptake inhibitors (SSRIs), a class of antidepressants, are first choice medication for generalized social phobia but a second line treatment. Compared to older forms of medication, there is less risk of tolerability and drug dependency associated with SSRIs.

In a 1995 double-blind, placebo-controlled trial, the SSRI paroxetine was shown to result in clinically meaningful improvement in 55 percent of patients with generalized social anxiety disorder, compared with 23.9 percent of those taking placebo. An October 2004 study yielded similar results. Patients were treated with either fluoxetine, psychotherapy, or a placebo. The first four sets saw improvement in 50.8 to 54.2 percent of the patients. Of those assigned to receive only a placebo, 31.7 percent achieved a rating of 1 or 2 on the Clinical Global Impression-Improvement scale. Those who sought both therapy and medication did not see a boost in improvement.

General side-effects are common during the first weeks while the body adjusts to the drug. Symptoms may include headaches, nausea, insomnia and changes in sexual behavior. Treatment safety during pregnancy has not been established. In late 2004 much media attention was given to a proposed link between SSRI use and suicidality [a term that encompasses suicidal ideation and attempts at suicide as well as suicide]. For this reason, [although evidential causality between SSRI use and actual suicide has not been demonstrated] the use of SSRIs in pediatric cases of depression is now recognized by the Food and Drug Administration as warranting a cautionary statement to the parents of children who may be prescribed SSRIs by a family doctor. Recent studies have shown no increase in rates of suicide. These tests, however, represent those diagnosed with depression, not necessarily with social anxiety disorder.

In addition, studies show that more socially phobic patients treated with anti-depressant medication develop hypomania than non-phobic controls. The hypomania can be seen as the medication creating a new problem.

Transmisogyny (sometimes trans-misogyny) is the intersection of transphobia and misogyny. Transphobia is defined as "the irrational fear of, aversion to, or discrimination against transgender or transsexual people". Misogyny is defined as "a hatred of women". Therefore, transmisogyny includes negative attitudes, hate, and discrimination of transgender or transsexual individuals who fall on the feminine side of the gender spectrum, particularly transgender women. The term was coined by Julia Serano in her 2007 book "Whipping Girl" and used to describe the unique discrimination faced by trans women because of "the assumption that femaleness and femininity are inferior to, and exist primarily for the benefit of, maleness and masculinity", and the way that transphobia intensifies the misogyny faced by trans women (and vice versa). It is said many trans women experience an additional layer of misogyny in the form of fetishization; Serano talks about how society views trans women in certain ways that sexualize them, such as them transitioning for sexual reasons, or ways where they’re seen as sexually promiscuous.Transmisogyny is a central concept in transfeminism and is commonly referenced in intersectional feminist theory. That trans women's femaleness (rather than only their femininity) is a source of transmisogyny is denied by certain radical feminists, who claim that trans women are not female.

The English suffixes -phobia, -phobic, -phobe (from Greek φόβος "phobos", "fear") occur in technical usage in psychiatry to construct words that describe irrational, abnormal, unwarranted, persistent, or disabling fear as a mental disorder (e.g. agoraphobia), in chemistry to describe chemical aversions (e.g. hydrophobic), in biology to describe organisms that dislike certain conditions (e.g. acidophobia), and in medicine to describe hypersensitivity to a stimulus, usually sensory (e.g. photophobia). In common usage, they also form words that describe dislike or hatred of a particular thing or subject (e.g. homophobia). The suffix is antonymic to -phil-.

For more information on the psychiatric side, including how psychiatry groups phobias such as agoraphobia, social phobia, or simple phobia, see phobia. The following lists include words ending in "-phobia", and include fears that have acquired names. In some cases, the naming of phobias has become a word game, of notable example being a 1998 humorous article published by "BBC News". In some cases, a word ending in "-phobia" may have an antonym with the suffix "-phil-", e.g. Germanophobe / Germanophile.

A large number of "-phobia" lists circulate on the Internet, with words collected from indiscriminate sources, often copying each other. Also, a number of psychiatric websites exist that at the first glance cover a huge number of phobias, but in fact use a standard text to fit any phobia and reuse it for all unusual phobias by merely changing the name. Sometimes it leads to bizarre results, such as suggestions to cure "prostitute phobia". Such practice is known as content spamming and is used to attract search engines.

An article published in 1897 in "American Journal of Psychology" noted "the absurd tendency to give Greek names to objects feared (which, as Arndt says, would give us such terms as klopsophobia – fear of thieves, triakaidekaphobia – fear of the number 13...".

Empirical studies have found that the prognosis for conversion disorder varies widely, with some cases resolving in weeks, and others enduring for years or decades. There is also evidence that there is no cure for Conversion Disorder, and that although patients may go into remission, they can relapse at any point. Furthermore, many patients who are 'cured' continue to have some degree of symptoms indefinitely.

Specialists may prefer to avoid the suffix "-phobia" and use more descriptive terms such as personality disorders, anxiety disorders, and avoidant personality disorder.
