Acrophobia, also known as hypsophobia, is an extreme or irrational fear or phobia of heights, especially when one is not particularly high up. It belongs to a category of specific phobias, called space and motion discomfort, that share similar causes and options for treatment.

Contents

Most people experience a degree of natural fear when exposed to heights, known as the fear of falling. On the other hand, those who have little fear of such exposure are said to have a head for heights. A head for heights is advantageous for hiking or climbing in mountainous terrain and also in certain jobs such as steeplejacks or wind turbine mechanics.

People with acrophobia can experience a panic attack in high places and become too agitated to get themselves down safely. Approximately 2–5% of the general population has acrophobia, with twice as many women affected as men. [1] The term is from the Greek : ἄκρον, ákron, meaning "peak, summit, edge" and φόβος, phóbos, "fear". The term "hypsophobia" derives from the Greek word ύψος (hypsos), meaning "height". In Greek, the actual term used for this condition is "υψοφοβία" (Hypsophobia).

Confusion with vertigo

"Vertigo" is often used to describe a fear of heights, but it is more accurately a spinning sensation that occurs when one is not actually spinning. It can be triggered by looking down from a high place, by looking straight up at a high place or tall object, or even by watching something (i.e. a car or a bird) go past at high speed, but this alone does not describe vertigo. True vertigo can be triggered by almost any type of movement (e.g. standing up, sitting down, walking) or change in visual perspective (e.g. squatting down, walking up or down stairs, looking out of the window of a moving car or train). Vertigo is called height vertigo when the sensation of vertigo is triggered by heights.

Height vertigo is caused by a conflict between vision, vestibular and somatosensory senses. [2] This occurs when vestibular and somatosensory systems sense a body movement that is not detected by the eyes. More research indicates that this conflict leads to both motion sickness and anxiety. [3] [4] [5] Confusion may arise in differentiating between height vertigo and acrophobia due to the conditions' overlapping symptom pools, including body swaying and dizziness. Further confusion can occur due to height vertigo being a direct symptom of acrophobia. [6]

Traditionally, acrophobia has been attributed, like other phobias, to conditioning or a traumatic experience. Recent studies have cast doubt on this explanation. [7] [5] Individuals with acrophobia are found to be lacking in traumatic experiences. Nevertheless, this may be due to the failure to recall the experiences, as memory fades as time passes. [8] To address the problems of self report and memory, a large cohort study with 1000 participants was conducted from birth; the results showed that participants with less fear of heights had more injuries because of falling. [9] [5] Psychologists Richie Poulton, Simon Davies, Ross G. Menzies, John D. Langley, and Phil A. Silva sampled subjects from the Dunedin Multidisciplinary Health and Development Study who had been injured in a fall between the ages of 5 and 9, compared them to children who had no similar injury, and found that at age 18, acrophobia was present in only 2 percent of the subjects who had an injurious fall but was present among 7 percent of subjects who had no injurious fall (with the same sample finding that typical basophobia was 7 times less common in subjects at age 18 who had injurious falls as children than subjects that did not). [10]

More studies have suggested a possible explanation for acrophobia is that it emerges through accumulation of non-traumatic experiences of falling that are not memorable but can influence behaviours in the future. Also, fear of heights may be acquired when infants learn to crawl. If they fell, they would learn the concepts about surfaces, posture, balance, and movement. [5] Cognitive factors may also contribute to the development of acrophobia. People tend to wrongly interpret visuo-vestibular discrepancies as dizziness and nausea and associate them with a forthcoming fall. [11] Experiencing these cognitive factors while associating them with the idea of falling may be enough to cause the same fear that would be expected after a traumatic fall.

A fear of falling, along with a fear of loud noises, is one of the most commonly suggested inborn or "non-associative" fears. The newer non-association theory is that a fear of heights is an evolved adaptation to a world where falls posed a significant danger. If this fear is inherited, it is possible that people can get rid of it by frequent exposure of heights in habituation. In other words, acrophobia could be associated with a lack of exposure to heights in early life. [12] The degree of fear varies, and the term phobia is reserved for those at the extreme end of the spectrum. Researchers have argued that a fear of heights is an instinct found in many mammals, including domestic animals and humans. Experiments using visual cliffs have shown human infants and toddlers, as well as other animals of various ages, to be reluctant in venturing onto a glass floor with a view of a few meters of apparent fall-space below it. [13] Although human infants initially experienced fear when crawling on the visual cliff, most of them overcame the fear through practice, exposure and mastery and retained a level of healthy cautiousness. [14] While an innate cautiousness around heights is helpful for survival, extreme fear can interfere with the activities of everyday life, such as standing on a ladder or chair, or even walking up a flight of stairs. It is uncertain if acrophobia is related to the failure to reach a certain developmental stage. Besides associative accounts, a diathetic-stress model is also very appealing for considering both vicarious learning and hereditary factors such as personality traits (i.e., neuroticism).

Another possible contributing factor is a dysfunction in maintaining balance. In this case, the anxiety is both well-founded and secondary. The human balance system integrates proprioceptive, vestibular and nearby visual cues to reckon position and motion. [15] [16] As height increases, visual cues recede and balance becomes poorer in people without acrophobia. [17] However, most people respond to such a situation by shifting to more reliance on the proprioceptive and vestibular branches of the equilibrium system.

Some people are known to be more dependent on visual signals than others. [18] People who rely more on visual cues to control body movements are less physically stable. [19] [5] An acrophobic, however, continues to over-rely on visual signals, whether because of inadequate vestibular function or incorrect strategy. Locomotion at a high elevation requires more than normal visual processing. The visual cortex becomes overloaded, resulting in confusion. Some proponents of the alternative view of acrophobia warn that it may be ill-advised to encourage acrophobics to expose themselves to height without first resolving the vestibular issues. Research is underway at several clinics. [20] Recent studies found that participants experienced increased anxiety not only when the height increased, but also when they were required to move sideways at a fixed height. [21]

A recombinant model of the development of acrophobia is very possible, in which learning factors, cognitive factors (e.g. interpretations), perceptual factors (e.g. visual dependence), and biological factors (e.g. heredity) interact to provoke fear or habituation. [5]

Assessment

ICD-10 and DSM-5 are used to diagnose acrophobia. [22] Acrophobia Questionnaire (AQ) is a self report that contains 40 items, assessing anxiety level on a 0–6 point scale and degree of avoidance on a 0–2 point scale. [23] [24] The Attitude Towards Heights Questionnaires (ATHQ) [25] and Behavioural Avoidance Tests (BAT) are also used. [5]

However, acrophobic individuals tend to have biases in self-reporting. They often overestimate the danger and question their abilities of addressing height relevant issues. [26] A Height Interpretation Questionnaire (HIQ) is a self-report to measure these height relevant judgements and interpretations. [24] The Depression Scale of the Depression Anxiety Stress Scales short form (DASS21-DS) is a self report used to examine validity of the HIQ. [24]

Treatment

Traditional treatment of phobias is still in use today. Its underlying theory states that phobic anxiety is conditioned and triggered by a conditional stimulus. By avoiding phobic situations, anxiety is reduced. However, avoidance behaviour is reinforced through negative reinforcement. [5] [27] Wolpe developed a technique called systematic desensitization to help participants avoid "avoidance". [28] Research results have suggested that even with a decrease in therapeutic contact, desensitization is still very effective. [29] However, other studies have shown that therapists play an essential role in acrophobia treatment. [30] Treatments like reinforced practice and self-efficacy treatments also emerged. [5]

There have been a number of studies into using virtual reality therapy for acrophobia. [31] [32] Botella and colleagues [33] and Schneider [33] were the first to use VR in treatment. [5] Specifically, Schneider utilised inverted lenses in binoculars to "alter" the reality. Later in the mid-1990s, VR became computer-based and was widely available for therapists. A cheap VR equipment uses a normal PC with head-mounted display (HMD). In contrast, VRET uses an advanced computer automatic virtual environment (CAVE). [34] VR has several advantages over in vivo treatment: [5] (1) therapist can control the situation better by manipulating the stimuli, [35] in terms of their quality, intensity, duration and frequency; [36] (2) VR can help participants avoid public embarrassment and protect their confidentiality; (3) therapist's office can be well-maintained; (4) VR encourages more people to seek treatment; (5) VR saves time and money, as participants do not need to leave the consulting room. [34]

Many different types of medications are used in the treatment of phobias like fear of heights, including traditional anti-anxiety drugs such as benzodiazepines, and newer options such as antidepressants and beta-blockers. [37]

Prognosis

Some desensitization treatments produce short-term improvements in symptoms. [38] Long-term treatment success has been elusive. [38]

Epidemiology

Approximately 2–5% of the general population has acrophobia, with twice as many women affected as men. [39]

A related, milder form of visually triggered fear or anxiety is called visual height intolerance (vHI). [40] Up to one-third of people may have some level of visual height intolerance. [40] Pure vHI usually has smaller impact on individuals compared to acrophobia, in terms of intensity of symptoms load, social life, and overall life quality. However, few people with visual height intolerance seek professional help. [41]

<span class="mw-page-title-main">Phobia</span> Anxiety disorder classified by a persistent and excessive fear of an object or situation

A phobia is an anxiety disorder, defined by an irrational, unrealistic, persistent and excessive fear of an object or situation. Phobias typically result in a rapid onset of fear and are usually present for more than six months. Those affected go to great lengths to avoid the situation or object, to a degree greater than the actual danger posed. If the object or situation cannot be avoided, they experience significant distress. Other symptoms can include fainting, which may occur in blood or injury phobia, and panic attacks, often found in agoraphobia and emetophobia. Around 75% of those with phobias have multiple phobias.

Paradoxical intention (PI) is a psychotherapeutic technique used to treat recursive anxiety by repeatedly rehearsing the anxiety-inducing pattern of thought or behaviour, often with exaggeration and humor. Paradoxical intention has been shown to be effective in treating psychosomatic illnesses such as chronic insomnia, public speaking phobias, etc. by making patients do the opposite of their hyper-intended goal, hindering their ability to perform the activity.

<span class="mw-page-title-main">Agoraphobia</span> Anxiety disorder

Agoraphobia is a mental and behavioral disorder, specifically an anxiety disorder characterized by symptoms of anxiety in situations where the person perceives their environment to be unsafe with no easy way to escape. These situations can include public transit, shopping centers, crowds and queues, or simply being outside their home on their own. Being in these situations may result in a panic attack. Those affected will go to great lengths to avoid these situations. In severe cases, people may become completely unable to leave their homes.

Specific phobia is an anxiety disorder, characterized by an extreme, unreasonable, and irrational fear associated with a specific object, situation, or concept which poses little or no actual danger. Specific phobia can lead to avoidance of the object or situation, persistence of the fear, and significant distress or problems functioning associated with the fear. A phobia can be the fear of anything.

Cognitive restructuring (CR) is a psychotherapeutic process of learning to identify and dispute irrational or maladaptive thoughts known as cognitive distortions, such as all-or-nothing thinking (splitting), magical thinking, overgeneralization, magnification, and emotional reasoning, which are commonly associated with many mental health disorders. CR employs many strategies, such as Socratic questioning, thought recording, and guided imagery, and is used in many types of therapies, including cognitive behavioral therapy (CBT) and rational emotive behaviour therapy (REBT). A number of studies demonstrate considerable efficacy in using CR-based therapies.

The Liebowitz Social Anxiety Scale (LSAS) is a short questionnaire developed in 1987 by Michael Liebowitz, a psychiatrist and researcher at Columbia University and the New York State Psychiatric Institute. Its purpose is to assess the range of social interaction and performance situations feared by a patient in order to assist in the diagnosis of social anxiety disorder. It is commonly used to study outcomes in clinical trials and, more recently, to evaluate the effectiveness of cognitive-behavioral treatments. The scale features 24 items, which are divided into two subscales. 13 questions relate to performance anxiety and 11 concern social situations. The LSAS was originally conceptualized as a clinician-administered rating scale, but has since been validated as a self-report scale.

Virtual reality therapy (VRT), also known as virtual reality immersion therapy (VRIT), simulation for therapy (SFT), virtual reality exposure therapy (VRET), and computerized CBT (CCBT), is the use of virtual reality technology for psychological or occupational therapy and in affecting virtual rehabilitation. Patients receiving virtual reality therapy navigate through digitally created environments and complete specially designed tasks often tailored to treat a specific ailment; and is designed to isolate the user from their surrounding sensory inputs and give the illusion of immersion inside a computer-generated, interactive virtual environment. This technology has a demonstrated clinical benefit as an adjunctive analgesic during burn wound dressing and other painful medical procedures. Technology can range from a simple PC and keyboard setup, to a modern virtual reality headset. It is widely used as an alternative form of exposure therapy, in which patients interact with harmless virtual representations of traumatic stimuli in order to reduce fear responses. It has proven to be especially effective at treating PTSD, and shows considerable promise in treating a variety of neurological and physical conditions. Virtual reality therapy has also been used to help stroke patients regain muscle control, to treat other disorders such as body dysmorphia, and to improve social skills in those diagnosed with autism.

<span class="mw-page-title-main">Cynophobia</span> Fear of dogs and canines

Cynophobia is the fear of dogs and canines in general. Cynophobia is classified as a specific phobia, under the subtype "animal phobias". According to Timothy O. Rentz of the Laboratory for the Study of Anxiety Disorders at the University of Texas, animal phobias are among the most common of the specific phobias and 36% of patients who seek treatment report being afraid of dogs or afraid of cats. Although ophidiophobia or arachnophobia are more common animal phobias, cynophobia is especially debilitating because of the high prevalence of dogs and the general ignorance of dog owners to the phobia. The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) reports that only 12% to 30% of those with a specific phobia will seek treatment.

<span class="mw-page-title-main">Exposure hierarchy</span>

In exposure therapy, an exposure hierarchy is developed to help clients confront their feared objects and situations in a manner that is systematic and controlled for the purpose of systematic desensitization. Exposure hierarchies are included in the treatment of a wide range of anxiety disorders.

Exposure therapy is a technique in behavior therapy to treat anxiety disorders. Exposure therapy involves exposing the patient to the anxiety source or its context. Doing so is thought to help them overcome their anxiety or distress. Numerous studies have demonstrated its effectiveness in the treatment of disorders such as generalized anxiety disorder (GAD), social anxiety disorder (SAD), obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and specific phobias.

Blood phobia is an extreme irrational fear of blood, a type of specific phobia. Severe cases of this fear can cause physical reactions that are uncommon in most other fears, specifically vasovagal syncope (fainting). Similar reactions can also occur with trypanophobia and traumatophobia. For this reason, these phobias are categorized as blood-injection-injury phobia by the DSM-IV. Some early texts refer to this category as "blood-injury-illness phobia."

Immersion therapy is a psychological technique which allows a patient to overcome fears (phobias), but can be used for anxiety and panic disorders.

Social anxiety is the anxiety and fear specifically linked to being in social settings. Some categories of disorders associated with social anxiety include anxiety disorders, mood disorders, autism spectrum disorders, eating disorders, and substance use disorders. Individuals with higher levels of social anxiety often avert their gazes, show fewer facial expressions, and show difficulty with initiating and maintaining a conversation. Social anxiety commonly manifests itself in the teenage years and can be persistent throughout life; however, people who experience problems in their daily functioning for an extended period of time can develop social anxiety disorder. Trait social anxiety, the stable tendency to experience this anxiety, can be distinguished from state anxiety, the momentary response to a particular social stimulus. Half of the individuals with any social fears meet the criteria for social anxiety disorder. Age, culture, and gender impact the severity of this disorder. The function of social anxiety is to increase arousal and attention to social interactions, inhibit unwanted social behavior, and motivate preparation for future social situations.

Interoceptive exposure is a cognitive behavioral therapy technique used in the treatment of panic disorder. It refers to carrying out exercises that bring about the physical sensations of a panic attack, such as hyperventilation and high muscle tension, and in the process removing the patient's conditioned response that the physical sensations will cause an attack to happen.

The fear of falling (FOF), also referred to as basophobia, is a natural fear and is typical of most humans and mammals, in varying degrees of extremity. It differs from acrophobia, although the two fears are closely related. The fear of falling encompasses the anxieties accompanying the sensation and the possibly dangerous effects of falling, as opposed to the heights themselves. Those who have little fear of falling may be said to have a head for heights. Basophobia is sometimes associated with astasia-abasia, the fear of walking/standing erect.

Driving phobia, driving anxiety, vehophobia, amaxophobia or driving-related fear (DRF) is a pathological fear of driving. It is an intense, persistent fear of participating in car traffic that affects a person's lifestyle, including aspects such as an inability to participate in certain jobs due to the pathological avoidance of driving. The fear of driving may be triggered by specific driving situations, such as expressway driving or dense traffic. Driving anxiety can range from a mild cautious concern to a phobia.

Anxiety sensitivity (AS) refers to the fear of behaviours or sensations associated with the experience of anxiety, and a misinterpretation of such sensations as dangerous. Bodily sensations related to anxiety, such as nausea and palpitations, are mistaken as harmful experiences, causing anxiety or fear to intensify. For example, a person with high anxiety sensitivity may fear the shakes as impending neurological disorder, or may suspect lightheadedness is the result of a brain tumour; conversely, a person with low anxiety sensitivity is likely to identify these as harmless and attach no significance to them. The Anxiety Sensitivity Index attempts to assess anxiety sensitivity.

Thought stopping (TS) is a cognitive self-control skill that can be used to counter dysfunctional or distressing thoughts, by interrupting sequences or chains of problem responses. When used with Cognitive Behavioural Therapy (CBT), it can act as a distraction, preventing an individual from focusing on their negative thought. Patients can replace a problematic thought with a positive one in order to reduce anxiety and worry. The procedure uses learning principles, such as counterconditioning and punishment. TS can be prescribed to address depression, panic, anxiety and addiction, among other afflictions that involve obsessive thought.

Safety behaviors are coping behaviors used to reduce anxiety and fear when the user feels threatened. An example of a safety behavior in social anxiety is to think of excuses to escape a potentially uncomfortable situation. These safety behaviors, although useful for reducing anxiety in the short term, might become maladaptive over the long term by prolonging anxiety and fear of nonthreatening situations. This problem is commonly experienced in anxiety disorders. Treatments such as exposure and response prevention focus on eliminating safety behaviors due to the detrimental role safety behaviors have in mental disorders. There is a disputed claim that safety behaviors can be beneficial to use during the early stages of treatment.

The Social Interaction Anxiety Scale (SIAS) is a self-report scale that measures distress when meeting and talking with others that is widely used in clinical settings and among social anxiety researchers. The measure assesses social anxiety disorder, which is fear or anxiety about one or more social situations where the individual is subject to possible scrutiny.
