People who seek help for fear of flying : Typology of flying phobics

The objective of this study was to examine sociodemographic and clinical characteristics of 419 patients who were self-referred to a treatment agency because of fear of flying. With the use of homogeneity analyses to explore the association between flight-anxiety and different types of phobia, four specific subtypes of flying phobics were identified. The subtypes differed in terms of flight-anxiety level, age, sex, complaints like “fear of aircraft accidents, the need to have control over the situation, fear of losing control over themselves,” and phobias underlying their fear of flying, such as claustrophobia, acrophobia, social phobia, and symptoms of panic attacks. It is argued that the typology identified could have implications for the selection of treatment components.

Multicomponent standardized treatment programs for fear of flying: Description and effectiveness

This paper has two objectives. The first is to describe a multimodal, standardized treatment program used by the VALK Foundation, an agency that specializes in the treatment of patients with fear of flying. The second is to present the results of an evaluation of this program, particularly with regard to the effectiveness of a 2-day cognitive-behavioral group treatment program and a 1-day behavioral group treatment program for flying phobics. On the basis of individualized assessment, patients (N = 1,026) were nonrandomly assigned to 1 of the 2 group treatment modalities. Self-report data and behavioral indicators for fear of flying were collected at pretreatment and at 3-, 6-, and 12-month follow-ups. Complete data were obtained from 757 participants. Results showed that both treatment programs produced statistically significant, clinically relevant decreases in self-reported anxiety and behavioral anxiety indices. This paper explains the procedures and outcomes of a well-established clinical program. Limitations of the study are discussed and future research suggested.

The Flight Anxiety Situations Questionnaire and the Flight Anxiety Modality Questionnaire: norms for people with fear of flying.

BACKGROUND The Flight Anxiety Situations Questionnaire (FAS) and the Flight Anxiety Modality Questionnaire (FAM) are widely used in clinical practice and research studies. The aim of this study was to derive norms for people suffering from fear of flying completing the FAS and FAM. METHODS The sample is composed of 2072 individuals suffering from fear of flying and 1012 non-patients. Means, standard deviations and percentile ranks for raw FAS and FAM subscale scores will be presented. Normative data are provided enabling the comparison of individual scores. RESULTS The results showed a conspicuous difference between the patient and non-patient samples. As a whole the patient group scored higher on the scale assessing the level of anxiety experienced in different flight or flight-related situations and on the scale measuring the symptoms of anxiety or anticipatory anxiety in flight situations than the normal controls. CONCLUSIONS The findings of this study suggest that the FAS and FAM questionnaires can be applied in the investigation of fearful flyers and the normal population. A considerable number of flying phobics obtained scores in the clinically significant range on the subscales assessing anticipatory anxiety, in-flight anxiety, generalized flight anxiety, somatic complaints and cognitive complaints.

Personality pathology and cognitive-behavioral treatment of fear of flying

Studies have been inconclusive about the influence of personality pathology on treatment outcome in anxiety disorders. In general, it has been presumed that treatment outcome is negatively influenced by the presence of personality pathology. This is a study of the prevalence of personality pathology among persons who were seeking help for fear of flying. Moreover, the effects of personality pathology on the results of a multimodal, standardized, cognitive-behavioral fear of flying treatment program employed by an agency that specializes in treating people with fear of flying were studied. Personality pathology was determined with a self-report questionnaire, which provides ICD-10 diagnoses of personality disorders and dimensional severity scores for personality pathology. Treatment outcome was assessed with three different fear of flying questionnaires. Based on clinical judgment after individual-case conceptualization, participants (N=922) were assigned to a particular treatment for fear of flying. Self-report data for fear of flying were collected at pretreatment and at 3, 6 and 12-month follow-ups in 659 participants who followed the 2-day treatment program. Moreover, the number of flights made in the year following treatment was determined.The results of this study showed that participants with personality pathology, mainly from cluster C (anxiety), report greater fear of flying before treatment than participants without personality pathology. After treatment fear of flying was significantly reduced. Presence of personality pathology was not predictive of the number of flights after treatment and scores on the VAFAS scale at short or long term. Only on two questionnaires for fear of flying collected at short-term participants with personality pathology obtained significantly higher scores, although the size of the differences was relatively small. It was concluded that participants with personality pathology also benefited from fear of flying treatment and that the presence of personality pathology although cannot be regarded as a contra indication for a standardized, cognitive-behavioral group treatment.

Anxiety sensitivity moderates the relationship of changes in physiological arousal with flight anxiety during in vivo exposure therapy

Physiological sensations and discomfort constitute the major symptoms reported by aviophobics. Anxiety sensitivity (AS) seems to moderate the relationship between self-reported somatic sensations and flight anxiety, and AS has been identified as a vulnerability factor for flight phobia. In this study we examined whether AS moderates the effects of somatic sensations and autonomic nervous system reactivity on flight anxiety induced by real flight. In fifty aviophobics participating in Cognitive Behaviour Group Therapy (CBGT), flight anxiety, somatic sensations and autonomic nervous system reactivity were assessed during a guided return flight. Results indicate that physiological reactivity interacted with AS. Changes in heart rate and parasympathetic activity were more strongly associated with changes in reported flight anxiety for high AS participants, and less for participants low on AS. Results did not indicate a moderating effect of AS on the relationship between self-reported somatic sensations and flight anxiety. Our results suggest that therapy for flight phobia might benefit from addressing the physical effect of anxiety, by means of cognitive restructuring and exposure to interoceptive stimuli, particularly in aviophobics high in AS.

Physiological reactivity to phobic stimuli in people with fear of flying

OBJECTIVE The nature of the relationship between physiological and subjective responses in phobic subjects remains unclear. Phobics have been thought to be characterized by a heightened physiological response (physiological perspective) or by a heightened perception of a normal physiological response (psychological perspective). METHOD In this study, we examined subjective measures of anxiety, heart rate (HR), and cardiac autonomic responses to flight-related stimuli in 127 people who applied for fear-of-flying therapy at a specialized treatment center and in 36 controls without aviophobia. RESULTS In keeping with the psychological perspective, we found a large increase in subjective distress (eta(2)=.43) during exposure to flight-related stimuli in the phobics and no change in subjective distress in the controls, whereas the physiological responses of both groups were indiscriminate. However, in keeping with the physiological perspective, we found that, within the group of phobics, increases in subjective fear during exposure were moderately strong coupled to HR (r =.208, P=.022) and cardiac vagal (r =.199, P=.028) reactivity. In contrast to predictions by the psychological perspective, anxiety sensitivity did not modulate this coupling. CONCLUSION We conclude that subjective fear responses and autonomic responses are only loosely coupled during mildly threatening exposure to flight-related stimuli. More ecologically valid exposure to phobic stimuli may be needed to test the predictions from the physiological and psychological perspectives.

Different Flying Histories in Flying Phobics: Association with Psychopathology and Treatment Outcome

INTRODUCTION Passengers experiencing fear of flying can threaten the safety of a flight, its passengers, and crew. In the present study we investigated the effect of different flying histories on the nature and treatment of fear of flying and attempted to determine the following: 1) the prevalence of different flying histories in a sample of self-referred flying phobics; 2) the demographic and psychopathologic characteristics of flying phobics differing with respect to flying history; and 3) the predictive value of different flying histories for treatment outcome. METHODS Of 2001 self-referred adults who applied for a flying treatment program, 85.6% reported that they had flown before and that their flights had been uneventful; 8.7% had no previous experience with flying; 5.7% had flown before and had experienced an eventful (5.4%) or even a traumatic flight (0.3%). RESULTS Participants who had never flown before reported higher levels of fear of flying (FAS, FAM, VAFAS), agoraphobia (FSS-III), and general anxiety (SCL-90). Moreover, these subjects showed significantly more anxiety reduction following a 1- or 2-d group treatment than the other participants (statistically corrected for any pretreatment differences). CONCLUSIONS For participants who had never flown before, anxiety probably primarily reflects more generalized avoidance tendencies and a proneness to over-predict the magnitude and intensity of their fear.
