DSM-IV TR 1. Fear of flying is not a specific disorder. 2. It is generally (though not always) regarded as a specific phobia "characterised by clinically significant anxiety provided by exposure to a specific feared object or situation, often leading to avoidance behaviour" (p.429) Other Phobias (a) Simple phobias (snakes, buttons, dentists, flying) (b) Social phobias: avoid social situations because they are afraid of embarrassing themselves (public speaking, public toilets etc.) (c) Agoraphobia: fear of being in public places in unfamiliar settings (public transport, theatres etc.) Note: It is possible that an individual can present with more than one type of phobia. Co-factors (e.g. mood) may trigger or maintain the phobia. Simple phobias are easier to treat than social phobias, which in turn are easier to treat than agoraphobia.

  • Specific Phobia: Flight
    ACTIVITAS NERVOSA SUPERIOR Activitas Nervosa Superior 2012, 54, No. 3-4 MINI REVIEW SPECIFIC PHOBIA: FLIGHT Matthew Laker Department of Psychiatry, First Faculty of Medicine, Charles University, Prague, Czech Republic Abstract The practice of air travel holds a unique place in modern human life. With the continually shrinking and interconnected world, full global mobility becomes increasingly important for a fully functional life for continually increasing numbers of people. However, while prevalence estimates vary it is undeniable that the fear of flying affects a very large number of people with consequences that are personal, professional, and aggregate economical. Although effective treatments do exist, the disorder’s high prevalence in both clinical and sub-clinical forms, “diagnostic trickiness”, and requirement for time consuming treatments make the disorder Aviophobia a continuing challenge. Key words: Aviophobia; Psychopathology; Stress; Specific phobia 1. INTRODUCTION Shortly following the Wright Brother’s innovation of flight in 1903, during World War I, a significant number of military pilots and air-crew became reluctant to fly, reporting somatic symptom such as gastric upset or insomnia. Military medical professionals, failing to identify a physiological basis for the symptom, instead identified them as somatic, and created the term “aero-neurosis” to describe the affliction (Anderson, 1919; Oakes & Bor, 2010). As varying degrees of predisposed vulnerability among flying personnel did clearly exist, the enhanced susceptibility to this affliction was attributed to “temperament or a family history of ‘nervous instability”. Following the end of World War I, interest in the disorder tracked that of the usage of military air power and declined until the early days of World War II where it was renewed by again, obviously an increasing number of cases due to the increase again in the usage of air power.

  • List of Phobias and Simple Cures.Pdf
    Phobia This article is about the clinical psychology. For other uses, see Phobia (disambiguation). A phobia (from the Greek: φόβος, Phóbos, meaning "fear" or "morbid fear") is, when used in the context of clinical psychology, a type of anxiety disorder, usually defined as a persistent fear of an object or situation in which the sufferer commits to great lengths in avoiding, typically disproportional to the actual danger posed, often being recognized as irrational. In the event the phobia cannot be avoided entirely the sufferer will endure the situation or object with marked distress and significant interference in social or occupational activities.[1] 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 sufferer's environment if attempting a diagnosis. The DSM-IV-TR states that if a phobic 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 (Suriphobia) 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 encounter mice in the environment no actual distress or impairment is ever experienced. Proximity and the degree to which escape from the phobic stimulus should also be considered. As the sufferer approaches a phobic stimulus, anxiety levels increase (e.g. as one gets closer to a snake, fear increases in ophidiophobia), and the degree to which escape of the phobic stimulus is limited and has the effect of varying the intensity of fear in instances such as riding an elevator (e.g.

  • How to Conquer Your Fear of Flying with a Return to Air Travel, Anxious Passengers Are Again Contending with This Common Phobia by Kim Painter, AARP, July 19, 2021 |
    How to Conquer Your Fear of Flying With a return to air travel, anxious passengers are again contending with this common phobia by Kim Painter, AARP, July 19, 2021 | XAVIERARNAU/GETTY IMAGES In February, right after she became fully vaccinated for COVID-19, writer Molly Jong- Fast took her first flight since March 2020. She brought along her therapist, just in case. Jong-Fast, 42, of New York City, is a lifelong fearful flyer who learned to cope years ago, she says, by facing her anxieties and flying frequently. But that 11-month gap had her worried that her anxieties might once again spiral out of control. Many flyers are feeling the same way, therapists say, as COVID-19 restrictions ease and planes fill up once more. It doesn't help, they say, that returning travelers are taking their seats at a time when unruly passengers are much in the news, sometimes due to conflict over mask wearing onboard (required by law). A return to the skies is especially fraught for those who were already afraid to fly. Because they are likely to have gone many months without flying due to the pandemic, “people who were fearful of flying before are finding their fears are more intense,” says Martin Seif, a psychologist specializing in anxiety disorders who practices in New York City and Greenwich, Connecticut. “They haven't done it in a while, and when you haven't done something in a while, your imagination takes over.” For the latest coronavirus news and advice go to AARP.org/coronavirus. Seif and other therapists say they tell fearful flyers that every flight they take can make the next flight easier.

  • Flying Phobia
    HOW TO BECOME A FEARFUL FLYER: THE LEARNING HISTORY OF FLYING PHOBIA Bettina Schindler Noortje Vriends Jürgen Margraf University of Basel, Switzerland Background Learning theory provides three models to explain the origins of phobias: Classical conditioning (Watson and Morgan, 1917; Mowrer, 1939) Vicarious learning (modeling) Informational learning (three-pathways account of Rachman, 1977) Recent literature tells us.... In studies about specific phobias the percentage of classical conditioning varies between 10% (Menzies, 1996) and 66% (Öst), depending on the kind of phobia and the methods that are used. There is only one study that examined conditioning processes in flying phobia (Wilhelm, 1997): Half of the participants with flying phobia reported some kind of traumatic event, about twice as many as in the control group.

  • Ways to Overcome Fear of Flying, Aviophobia by Phoebe Parlade and Paul R
    Ways to Overcome Fear of Flying, Aviophobia by Phoebe Parlade and Paul R. Burns Published on the CPANCF.COM website Clinical Psychology E-magazine Oct-Dec, 2018 Aviophobia is a psychological term for a fear of flying. It is estimated that one out of every six people in the United States has a phobia about flying. Those with a fear of flying are estimated to make only a third of the airline trips that those without such fears take (Dean & Whitaker, 1982). People with this phobia may avoid flying because of the anxiety and fear it causes them. To help cope, fearful flyers may drink alcohol or take medication to help them get through the experience. Fortunately, many people can learn to overcome their fear of flying and reduce the amount of distress this activity may cause them. Phobias involve patterns of anxiety or avoidance associated with events, objects, places, or activities that can interfere with functioning and/or cause personal distress. The individual may experience fearful beliefs and and may experience physiological anxiety reactions (such as body tenseness, increased heart rate, nausea, etc.). These symptoms arise due to the perceived threat or danger of flying. This can in turn cause avoidance which produces short term relief of the uncomfortable thoughts or feelings that then further reinforcing more fear and avoidance. Many people with aviophobia want to overcome it after experiencing the frustration that arises when they are prevented from necessary air travel to visit family or travel on business trips. In many cases, they seek methods or assistance to get past their fear to enjoy the benefits of flying.

  • Virtual Reality As Treatment for Fear of Flying: a Review of Recent Research Matthew Price, Page Anderson, Georgia State University, and Barbara O
    Price, et. al, Virtual Reality as Treatment for Fear of Flying: A Review of Recent Research Matthew Price, Page Anderson, Georgia State University, and Barbara O. Rothbaum, Emory University School of Medicine Virtual reality exposure has recently emerged as an important tool for exposure therapy in the treatment of fear of flying. There have been numerous empirical studies that have evaluated the effectiveness of virtual reality exposure as compared to other treatments including in vivo exposure, progressive muscle relaxation, cognitive therapy, bibliotherapy, and supportive group therapy. The results of two case studies and eight outcome trials have indicated that virtual reality exposure is comparable or superior to these treatments. However, the best results, as indicated by a reduction in self reported anxiety and fear experienced during an actual flight, were obtained when virtual reality exposure is combined with cognitive interventions. Virtual Reality (VR) has recently become an because it is not always logistically possible to excellent means for conducting exposure therapy control, prolong, and repeat exposure to aspects of (Krijn, Emmelkamp, Olafsson, & Biemond, 2004). flying.

  • Anxiety Disorders
    Anxiety Disorders Differential Diagnosis Generalized anxiety disorder: Separation anxiety disorder is distinguished from generalized anxiety disorder in that the anxiety predominantly concerns separation from attachment figures, and if other worries occur, they do not predominate the clinical picture. Panic disorder: Threats of separation may lead to extreme anxiety and even a panic attack. In separation anxiety disorder, in contrast to panic disorder, the anxiety concerns the possibility of being away from attachment figures and worry about untoward events befalling them, rather than being incapacitated by an unexpected panic attack. Agoraphobia: Unlike individuals with agoraphobia, those with separation anxiety disorder are not anxious about being trapped or incapacitated in situations from which escape is perceived as difficult in the event of panic-like symptoms or other incapacitating symptoms. Conduct disorder: School avoidance (truancy) is common in conduct disorder, but anxiety about separation is not responsible for school absences, and the child or adolescent usually stays away from, rather than returns to, the home. Social anxiety disorder: School refusal may be due to social anxiety disorder (social phobia). In such instances, the school avoidance is due to fear of being judged negatively by others rather than to worries about being separated from the attachment figures. Posttraumatic stress disorder: Fear of separation from loved ones is common after traumatic events, such as disasters, particularly when periods of separation from loved ones were experienced during the traumatic event. In posttraumatic stress disorder (PTSD), the central symptoms concern intrusions about, and avoidance of, memories associated with the traumatic event itself, whereas in separation anxiety disorder, the worries and avoidance concern the well-being of attachment figures and separation from them.
