About this study
Official title: An Internet-based Treatment for Flying Phobia Using 360º Images: A Feasibility Pilot Study
Flying phobia (FP) is one of the most prevalent phobias in our society. However, not all patients benefit from in vivo exposure, given that an important amount of them do not accept the intervention, drop out when they are informed about the intervention procedure, or have problems accessing these therapies.
The aim of the present study is to conduct a feasibility pilot with NO-FEAR Airlines ICBT (Campos et al., 2016) using two types of images in the exposure scenarios (still images vs 360º navigable images). A secondary aim is to explore the potential effectiveness of the two active treatment arms compared to a waiting list control group. Finally, we will explore the role of navigable images compared to the still images in the level of anxiety, sense of presence, and reality judgment in the exposure scenarios and whether the aforementioned variables mediate in treatment efficacy.
Regarding the main aim of this study, we hypothesize that both treatment conditions will be well accepted by the participants, but participants will prefer 360º images over still images.
Read the detailed description
Flying phobia (FP) is one of the most prevalent phobias in our society. Around 25% of the population that flies experiences intense distress during the flight; around 10% of the general population does not fly due to intense fear and 20% of people depend on alcohol or tranquilizers to overcome the fear of flying.
In vivo exposure is the most effective psychological treatment for specific phobias. However, not all patients benefit from in vivo exposure, given that an important amount of them do not accept the intervention, drop out when they are informed about the intervention procedure, or they have problems to access these therapies.
Information and Communication Technologies (ICTs) can improve treatment adherence and acceptance. Particularly, computerized programs offer remarkable advantages such as a reduction in direct therapeutic contact time, the possibility of standardizing treatment as much as possible with a steep exposure gradient, the low cost and, maybe most importantly, access to patients who would not be very willing to subject themselves to in vivo exposure. The application of cognitive-behavioural procedures such as exposure through interactive computer programs is especially recommended.
On the other hand, it is important to explore the role of the degree of immersion and sense of presence in the psychological treatments with iCBTs due to the contradictory conclusions that had been found in the literature. Therefore, it is expected that the present work advances in the knowledge in this field exploring these factors in an Internet-based self-applied treatment program for FP evaluating if a change in the exposure images used in the program NO-FEAR Airlines (Campos et al., 2016) will be feasible in a future RCT.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
NO-FEAR AirlinesBehavioural
"NO-FEAR Airlines" is an Internet-based self-applied treatment program that allows people with Flying Phobia the exposure to images and sounds related to their phobic fears on a standard personal computer. The treatment can be totally self-applied.
"NO-FEAR Airlines" contains 6 scenarios related to the flight process: (1) flight preparation, (2) airport, (3) boarding and taking off, (4) the central part of the flight, (5) the airplane's descent, approach to the runway, and landing, (6) sequences with images and auditory stimuli related to plane crashes.
| Study group | Role | What they receive |
|---|---|---|
| "NO-FEAR Airlines" program with still images | Experimental | Intervention group that uses "NO-FEAR Airlines" program with still images to carry out the exposure. Receives: Behavioral: NO-FEAR Airlines |
| "NO-FEAR Airlines" program with still and navigable images | Experimental | Intervention group that uses "NO-FEAR Airlines" program with still and navigable images to carry out the exposure. Receives: Behavioral: NO-FEAR Airlines |
| Waiting list control group | No intervention | Participants of this group are able to access "NO-FEAR Airlines" program after 6 weeks of waiting period. After that period, those participants still interested in receiving assistance are randomly assigned to one of two intervention conditions (only still images or still + navigable images). |
What is being measured
The primary outcome is the main question the study is designed to answer.
Expectations Scale and Satisfaction Scale (adapted from Borkovec & Nau, 1972)
This self-report inventory measures the patients' expectations before they start the treatment and after they receive a brief explanation about the intervention and their experimental condition. The same questions have to be answered when the patient completes the treatment in order to assess satisfaction. The 6 items are rated from 1 ("Not at all") to 10 ("Highly").
Measured: Up to 12 months
Preferences questionnaire
This questionnaire collects the patient's preferences regarding the two types of images included in this study (navigable and still images) through 5 dichotomous questions where they have to choose one of the two conditions. Participants will answer these questions before the treatment and before knowing the condition to which they are allocated (after the characteristics of each type of image are explained) and after they have completed the treatment (and after seeing a short video showing the image condition they did not receive).
Measured: Up to 12 months
Qualitative Interview
This interview assesses the participant's opinion of the intervention program after finishing it. The interview contains 13 items that the patient has to rate on a scale ranging from 1 ("very little") to 5 ("very much") and explain the reasons for their rating on each question. There are also two open questions where the participants have to give their overall opinion about the intervention program and the program images. In this interview, the perceived sense of presence and reality judgement in each scenario will also be assessed.
Measured: Up to 12 months
Secondary outcomes (5)
Fear and Avoidance Scales (adapted from Marks & Mathews, 1979)
Participants assessed their fear, avoidance and belief in catastrophic thought on a scale ranging from 0 ("No fear at all," "I never avoid") to 10 ("Severe fear," "I always avoid") for situations related with flying.
Measured: Up to 12 months
The Clinician Severity Scale (adapted from Di Nardo, Brown & Barlow, 1994).
The clinician rates the severity of the patient's phobia on a scale from 0 to 8, where 0 = symptom free and 8 = extremely severe.
Measured: Up to 12 months
Patient's Improvement Scale (Adapted from the Clinical Global Impression scale, CGI; Guy, 1976).
One item on the CGI scale was adapted in order to assess the level of improvement achieved by the patient (compared to the baseline) on a 7-point scale (1 "much worse" to 7 "much better"). This scale is answered by the patient.
Measured: Up to 12 months
Fear of Flying Questionnaire (FFQ-II; Bornas et al, 1999)
The FFQ is a 30-item self-report questionnaire that assesses the anxiety the person feels in different situations of the flight process: anxiety during the flight, anxiety experienced getting on the plane, and anxiety experienced due to the observation of neutral or unpleasant flying-related situations. For each item, respondents rate their degree of discomfort associated with the situation on a scale from 1 to 9 (1 = not at all, 9 = very much). Scores range from 30 to 270. Internal consistency was α = .97, and test-retest reliability (15-day retest period) was r = .92 (Bornas et al. 1999).
Measured: Up to 12 months
Fear of Flying Scale (FFS; Haug et al., 1987).
The FFS is a 21-item self-report measure to assess fear in different flying situations. Fear elicited by each situation was rated on a 4-point scale (1= not at all, 4 = very much), with scores ranging from 21 to 84. The original FFS reported a Cronbach's alpha of .94 and retest reliability (after a three-month period) of .86 (Haug et al., 1987).
Measured: Up to 12 months
