About

The purpose of this study is to determine the efficacy of a computer-aided self-help treatment for flying phobia with or without support by the therapist, compared to a waiting list control group.

Secondary objectives: a) to explore two ways of delivering NO-FEAR Airlines, with or without therapist guidance and b) to study the patients' acceptability through expectations, preferences and satisfaction towards the online program. In this work, we present the study design.

The principal hypothesis is that the two intervention groups will improve significantly compared to the waiting list control group.

Full description

One of the most prevalent phobias in our society is the fear of flying or flying phobia (FP). Surveys which identify clinically significant phobias estimate point prevalence at approximately 2.5% of the adult population. Around 10% of the general population do not fly due to intense fear, 25% of the population that fly experience intense distress during the flight and 20% of people depend on alcohol or tranquilizers to overcome the fear of flying.

The most effective psychological technique for the treatment of phobias is in vivo exposure. Besides, not all patients benefit from in vivo exposure, given that an important amount of them do not accept the intervention or drop out (around 25%) when they are informed about the intervention procedure or they have problems to access to these therapies.

Information and Communication Technologies (ICT) are pioneer applications that can improve treatment adherence and acceptance. Specifically, Computerized programs boasts remarkable advantages beyond strictly therapeutic and effectiveness-related ones in treating fear of flying: a reduction in direct therapeutic contact time, the possibility of standardizing treatment to the maximum, the low cost - which allows a greater extension - and, perhaps most importantly, access to patients who would not be very willing to subject themselves to live exposure (a real flight) with a steep exposure gradient. The application of cognitive-behavioural procedures such as exposure through interactive computer programs is especially recommended.

Enrollment: 69 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Be older than 18 years of age,
• To meet current DSM-5 criteria for specific phobia (flying phobia).
• Be willing to participate in the study.
• Be able to use a computer and having an Internet connection at home.
• Be able to understand and read Spanish.
• Have an e-mail address.

Exclusion criteria

• Be receiving psychological treatment for fear of flying.
• A severe mental disorder: abuse or dependence of alcohol or other substances, psychotic disorder, dementia or bipolar disorder.
• Presence of depressive symptomatology, suicidal ideation or plan.
• Presence of heart disease.
• Pregnant women (from the fourth month).

Receiving pharmacological treatment is not an exclusion criterion during the study period, but the increase, decrease and/or change in the medication during the study period will imply the participant's exclusion from subsequent analyses.

Participants with comorbid and related disorders (i.e., panic disorder, agoraphobia, claustrophobia or acrophobia) will be included once flying phobia is the primary diagnosis. In contrast, participants who do not meet inclusion criteria will be encouraged to seek treatment alternatives better suited to their specific needs.

Masking: Single Blind

---

69 participants in 3 patient groups

Group without support by the therapist

Experimental group

Description:

Intervention group that do the "NO-FEAR Airlines" program and does not receive support by the therapist.

Treatment:

Behavioral: NO-FEAR Airlines

Group with support by the therapist

Experimental group

Description:

Intervention group that do the "NO-FEAR Airlines" program and receives support by the therapist (a brief weekly five-minutes call).

Treatment:

Behavioral: NO-FEAR Airlines

Waiting list control group

Other group

Description:

Control group that could access the "NO-FEAR Airlines" program after waiting for 6 weeks. After that time, those participants still interested were randomly assigned to one of two intervention conditions (with or without support by the therapist).

Treatment:

Behavioral: NO-FEAR Airlines
