Certain children who are particularly attached to their mother or other family figure due to separation anxiety and/or attachment theory often suffer the onset early, in pre-school, crèche or before school starts.

School phobia is diagnosed primarily through questionnaires and interviews with doctors. Other methods like observation have not proven to be as useful. This is partly because (school) anxiety is an internal phenomenon. An example of a modern multidimensional questionnaire is the "Differential Power Anxiety Inventory 'approach, with twelve scales to diagnose four different areas: anxiety-inducing conditions, manifestations, coping strategies and stabilization forms."

- Cognitive and lifestyle exploration

- 'School Phobia Test' (SAT)

- 'Anxiety questionnaire for students', (AFS)

Approximately 1 to 5% of school-aged children have school refusal, though it is most common in 5- and 6-year olds and in 10- and 11-year olds, it occurs more frequently during major changes in a child’s life, such as entrance to kindergarten, changing from elementary to middle school, or changing from middle to high school. The problem may start following vacations, school holidays, summer vacation, or brief illness, after the child has been home for some time, and usually ends prior to vacations, school holidays, or summer vacation, before the child will be out of school for some time. School refusal can also occur after a stressful event, such as moving to a new house, or the death of a pet or relative.

The rate is similar within both genders, and although it is significantly more prevalent in some urban areas, there are no known socioeconomic differences.

Stage fright or performance anxiety is the anxiety, fear, or persistent phobia which may be aroused in an individual by the requirement to perform in front of an audience, whether actually or potentially (for example, when performing before a camera). In the context of public speaking, this may precede or accompany participation in any activity involving public self-presentation. In some cases stage fright may be a part of a larger pattern of social phobia (social anxiety disorder), but many people experience stage fright without any wider problems. Quite often, stage fright arises in a mere anticipation of a performance, often a long time ahead. It has numerous manifestations: stuttering, tachycardia, tremor in the hands and legs, sweaty hands, facial nerve tics, dry mouth, and dizziness.

Stage fright may be observed in people of all experiences and backgrounds, from those who are completely new to being in front of an audience to those who have done so for years. It is commonly known among everyday people and may, for example, affect their confidence in job interviews. It also affects actors, comedians, musicians, and politicians. Many people with no other problems in communication can experience stage fright, but some people with chronic stage fright also have social anxiety or social phobia which are chronic feelings of high anxiety in any social situation. Stage fright can also be seen in school situations, like stand up projects and class speeches.

Dogs suffering from separation anxiety are often "owner addicts". Setting boundaries will boost a dog's confidence and prepare it to be on its own.

Various techniques have been suggested for helping dogs cope with separation anxiety:

- Leaving and returning home quietly, without fuss

- Providing plenty of exercise, play, and fun

- Practicing leaving to adjust the dog to your departure

- Feeding the dog before you leave

- Leaving the radio/TV on

- Medicating the dog

As of 2012, a San Diego cable channel is offering DOGTV, a cable-based television channel especially for dogs whose owners are away. The programming, created with the help of dog behavior specialists, is color-adjusted to appeal to dogs, and features 3–6 minute segments designed to relax, to stimulate, and to expose the dog to scenes of everyday life such as doorbells or riding in a vehicle. The channel's proponents have indicated positive reviews from a humane society shelter in Escondido, California. The "doggie resort" hosts of the opening party for Dog TV in San Diego reported that some of their dogs seem to enjoy watching the animated series "SpongeBob SquarePants". The show's creators anticipate that dogs will watch Dog TV intermittently, throughout the day, rather than remaining glued to the set.

Another technology based solution for calming separation anxious dogs is a software named Digital Dogsitter.

The user first records his or her voice to the software. When the dog is alone, the software listens to the dog and analyzes the incoming audio through the computer's microphone. Whenever the dog barks or howls, software plays the owner's voice to the dog, and the dog becomes calm.

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.

As noted by Altman, McGoey & Sommer, it is important to observe the child, "in multiple contexts, on numerous occasions, and in their everyday environments (home, daycare, preschool)". It is beneficial to view parent and child interactions and behaviors that may contribute to SAD.

Dyadic Parent-Child Interaction Coding System and recently the Dyadic Parent-Child Interaction Coding System II (DPICS II) are methods used when observing parents and children interactions.

Separation Anxiety Daily Diaries (SADD) have also been used to “assess anxious behaviors along with their antecedents and consequences and may be particularly suited to SAD given its specific focus on parent–child separation” (Silverman & Ollendick, 2005). The diaries are carefully evaluated for validity.

At the preschool-aged stage, early identification and intervention is crucial. The communication abilities of young children are taken into consideration when creating age-appropriate assessments.

A commonly used assessment tool for preschool-aged children (ages 2–5) is the Preschool Age Psychiatric Assessment (PAPA). Additional questionnaires and rating scales that are used to assess the younger population include the Achenbach Scales, the Fear Survey Schedule for Infants and Preschoolers, and The Infant–Preschool Scale for Inhibited Behaviors.

Preschool children are also interviewed. Two interviews that are sometimes conducted are Attachment Doll-Play and Emotional Knowledge. In both of the assessments the interviewer depicts a scenario where separation and reunion occur; the child is then told to point at one of the four facial expressions presented. These facial expressions show emotions such as anger or sadness. The results are then analyzed.

Behavioral observations are also utilized when assessing the younger population. Observations enable the clinician to view some of the behaviors and emotions in specific contexts.

Homesickness is the distress caused by being away from home. Its cognitive hallmark is preoccupying thoughts of home and attachment objects. Sufferers typically report a combination of depressive and anxious symptoms, withdrawn behavior and difficulty focusing on topics unrelated to home.

In its mild form, homesickness prompts the development of coping skills and motivates healthy attachment behaviors, such as renewing contact with loved ones. Indeed, nearly all people miss something about home when they are away, making homesickness a nearly universal experience. However, intense homesickness can be painful and debilitating.

Fortunately, prevention and treatment strategies exist for both children and adults. There are protective factors which can help people to cope with homesickness. Youth-serving organizations, such as the American Camp Association, have developed a homesickness prevention program. One study showed that this inexpensive intervention can lower the intensity of homesickness of first-year campers by an average 50%.

As an important side note when the elderly are moved, not of their own desire, into a nursing home and out of their own home they are more vulnerable to death due to the stress of homesickness. More studies are needed on this, however, the patient's dislike of the new nursing home seems to cancel out the care newly or better provided.

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

Risk factors (constructs which increase the likelihood or intensity of homesickness) and protective factors (constructs that decrease the likelihood or intensity of homesickness) vary by population. For example, a seafarers on board, the environmental stressors associated with a hospital, a military boot camp or a foreign country may exacerbate homesickness and complicate treatment. Generally speaking, however, risk and protective factors transcend age and environment.

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

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

Many people report stress-induced speech disorders which are only present during public speech. Some individuals with glossophobia have been able to dance, perform in public, or even to speak (such as in a play), or sing if they cannot see the audience, or if they feel that they are presenting a character or stage persona other than themselves. Being able to blend in a group (as in a choir or band) has been reported to also alleviate some anxiety caused by glossophobia.

It has been estimated that 75% of all people experience some degree of anxiety/nervousness when it comes to public speaking. In fact, surveys have shown that most people fear public speaking more than they fear death. If untreated, public speaking anxiety can lead to serious detrimental effects on one's quality of life, career goals and other areas. For example, educational goals requiring public speaking might be left unaccomplished. However, not all persons with public speaking anxiety are necessarily unable to achieve work goals, though this disorder becomes problematic when it prevents an individual from attaining or pursuing a goal they might otherwise have - were it not for their anxiety.

A recent study conducted by Garcia-Lopez, Diez-Bedmar, and Almansa-Moreno (2013) has reported that previously trained students could act as trainers to other students and help them to improve their public speaking skills.

Death anxiety is anxiety which is caused by thoughts of death. One source defines death anxiety as a "feeling of dread, apprehension or solicitude (anxiety) when one thinks of the process of dying, or ceasing to 'be'". It is also referred to as thanatophobia (fear of death), and is distinguished from necrophobia, which is a specific fear of dead or dying persons and/or things (i.e. others who are dead or dying, not one's own death or dying).

Additionally, there is anxiety caused by death-related thought-content, which might be classified within a clinical setting by a psychiatrist as morbid and/or abnormal, which for classification pre-necessitates a degree of anxiety which is persistent and interferes with everyday functioning. Lower ego integrity, more physical problems, and more psychological problems are predictive of higher levels of death anxiety in elderly people because of how close to death they are.

It is during the years of young adulthood (20 to 40 years of age) that death anxiety most often begins to become prevalent. However, during the next phase of life, the middle age adult years (40–64 years of age), death anxiety peaks at its highest levels when in comparison to all other age ranges throughout the lifespan. Surprisingly, levels of death anxiety then slump off in the old age years of adulthood (65 years of age and older). This is in contrast with most people’s expectations, especially regarding all of the negative connotations younger adults have about the elderly and the aging process (Kurlychek & Trenner, 1982).

The prevalence of scrupulosity is speculative. Available data do not permit reliable estimates, and available analyses mostly disregard associations with age or with gender, and have not reliably addressed associations with geography or ethnicity. Available data suggest that the prevalence of obsessive–compulsive disorder does not differ by culture, except where prevalence rates differ for all psychiatric disorders. No association between OCD and depth of religious beliefs has been demonstrated, although data are scarce. There are large regional differences in the percentage of OCD patients who have religious obsessions or compulsions, ranging from 0–7% in countries like the U.K. and Singapore, to 40–60% in traditional Muslim and orthodox Jewish populations.

Glossophobia or speech anxiety is the fear of public speaking. The word "glossophobia" derives from the Greek γλῶσσα "glōssa", meaning tongue, and φόβος "phobos", fear or dread. Some people have this specific phobia, while others may also have broader social phobia or social anxiety disorder.

Stage fright may be a symptom of glossophobia.

The cause of dog separation anxiety is unknown, but may be triggered by:

- a traumatic event

- a change in routine

- major life change (e.g., new home, new baby, death of a family member, abandonment to a shelter)

- extreme attachment or dependency on the owner

Treatment is similar to that for other forms of obsessive–compulsive disorder. Exposure and response prevention (ERP), a form of behavior therapy, is widely used for OCD in general and may be promising for scrupulosity in particular. ERP is based on the idea that deliberate repeated exposure to obsessional stimuli lessens anxiety, and that avoiding rituals lowers the urge to behave compulsively. For example, with ERP a person obsessed by blasphemous thoughts while reading the Bible would practice reading the Bible. However, ERP is considerably harder to implement than with other disorders, because scrupulosity often involves spiritual issues that are not specific situations and objects. For example, ERP is not appropriate for a man obsessed by feelings that God has rejected and is punishing him. Cognitive therapy may be appropriate when ERP is not feasible. Other therapy strategies include noting contradictions between the compulsive behaviors and moral or religious teachings, and informing individuals that for centuries religious figures have suggested strategies similar to ERP. Religious counseling may be an additional way to readjust beliefs associated with the disorder, though it may also stimulate greater anxiety.

Little evidence is available on the use of medications to treat scrupulosity. Although serotonergic medications are often used to treat OCD, studies of pharmacologic treatment of scrupulosity in particular have produced so few results that even tentative recommendations cannot be made.

Treatment of scrupulosity in children has not been investigated to the extent it has been studied in adults, and one of the factors that makes the treatment difficult is the fine line the therapist must walk between engaging and offending the client.

Hedonophobia is an excessive fear or aversion to obtaining pleasure. The purported background of some such associated feelings may be due to an egalitarian-related sentiment, whereby one feels a sense of solidarity with individuals in the lowest Human Development Index countries. For others, a recurring thought that some things are too good to be true has resulted in an ingrainedness that they are not entitled to feel too good. The condition is relatively rare. Sometimes, it can be triggered by a religious upbringing wherein asceticism is propounded.

Hedonophobia is formally defined as the fear of experiencing pleasure. 'Hedon' or 'hedone' comes from ancient Greek, meaning 'pleasure' + fear: 'phobia'. Hedonophobia is the inability to enjoy pleasurable experiences, and is often a persistent malady. Diagnosis of the condition is usually related to the age of 'maturity' in each country where the syndrome exists. For instance, in the US a person must be 18 years old to be considered an adult, whereas in Canada he or she must be 18 or 19 years old, depending on the province of residence. Globally, the ages range from (+/-) 12 to 24 years and are mainly determined by traditional ethical practices from previous societies. High anxiety, panic attacks, and extreme fear are symptoms that can result from anticipating pleasure of any kind. Expecting or anticipating pleasure at some point in the future can also trigger an attack.

Hedonophobics have a type of guilt about feeling pleasure or experiencing pleasurable sensations, due to a cultural background or training (either religious or cultural) that eschews pleasurable pursuits as frivolous or inappropriate. Oftentimes, social guilt is connected to having fun while others are suffering, and is common for those who feel undeserving or have self-worth issues to work through. Also, there is a sense that they shouldn't be given pleasures due to their lack of performance in life, and because they have done things that are deemed "wrong" or "undeserving."

To determine the depth of the diagnosis for those who suffer from hedonophobia, background is crucial. For example, when a child is taught that a strong work ethic is all that makes them worthy of the good things in life, guilt becomes a motivator to move away from pleasure when they begin to experience it. The individual learns that pleasures are bad, and feeling good is not as sanctified as being empathetic towards those who suffer.

C.B.T. (Cognitive Behavioral Therapy) is an effective approach to the resolution of past beliefs that infiltrate and affect the sufferer's current responses to various situations. Medication is only necessary when there is an interference in the person's normal daily functioning. Various techniques are used by those afflicted with the condition to hide, camouflage or mask their aversion to pleasure.

Any relationship that includes things that are pleasurable is re-established when the sufferer learns that he is not worthy of anything pleasurable, or that he only deserves the opposite of those things which are pleasurable. A disconnect is necessary to determine the sufferer's lack of ability to intervene in the overall process.

Some medical practitioners are open to a patient's personal research, as this can open lines of communication between doctors and patients, and prove valuable in eliciting more complete or pertinent information from the patient about their present condition.

Other doctors express concern about patients who self-diagnose on the basis of information obtained from the Internet when the patient demonstrates an incomplete or distorted understanding of other diagnostic possibilities and medical likelihoods. A patient who exaggerates one set of symptoms in support of their self-diagnosis while minimizing or suppressing contrary symptoms can impair rather than enhance a doctor's ability to reach a correct diagnosis.

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).

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.

Specific treatments are not mentioned. The affected person may go to a medical clinic that specializes in sexual health. If no medical problems are found, therapy may be used to help deal with stress, or anxiety medicines may be used.

Disorders, who they affect, and how they affect are different within each culture. In order to diagnose someone, it is necessary to make the effort to understand their home culture. Whether it is a culture bound syndrome or not, a person’s background determines how they see and interpret their own symptoms and how it must be treated.
