Plain English Summary
Background and study aims
Agoraphobia is a type of anxiety disorder where a person fears being in situations and places where they feel trapped or in danger, often because of openness or crowdedness. Although many believe it is just a fear of open or public places, it is much more complex and usually involves a range of different fears. In general, it can render people unable to function and the condition traps sufferers in a vicious cycle, preventing them from leaving home to seek the support or to attend treatment that might end the condition. Depending on how severe the condition is treatment may require one-to-one therapy in a patient's home and for the person to be escorted around the surrounding area, but this is often expensive and time-consuming. "Agoraphobia Free" is a new therapeutic app which aims to break this cycle by putting the two components of traditional treatment, namely education and exposure therapy (gradually exposing someone to their fear until it no longer scares them), in the hands of the users themselves via their phones or tablets. This study aims to look at the effectiveness of using the app for six weeks on the severity of symptoms in self-reported agoraphobia sufferers.
Who can participate?
Adults who suffer from agoraphobia.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group are given access to the “Agoraphobia Free” app, which is designed specifically to help people with agoraphobia, for a total of 12 weeks. The app features game play to make therapy sessions as engaging as possible, exposing users to virtual environments likely to trigger their fears. They are also taught ways of dealing with their fears within the app so that they are no longer as frightening. Those in the second group are given access to a more generalized app called “Stress Free”, which is designed to help people with anxiety in general, for a total of 12 weeks. This app involves teaching the user techniques such as calm breathing, relaxation and meditation, designed to lower anxiety levels. At the start of the study and then again after six and 12 weeks, participants in both groups complete a number of questionnaires in order to assess the severity of their agoraphobia symptoms.
What are the possible benefits and risks of participating?
Participants may benefit from an improvement to their feelings of anxiety as well as increased knowledge about their condition. There are no notable risks of taking part in the study.

| Scientific title | Clinical effectiveness of a mobile phone application to treat agoraphobia with and without panic disorder (PD) in a community-based sample |
| Study acronym | Evaluation of Agoraphobia Free |
| Study hypothesis | The aim of this study is to examine whether the agoraphobia-specific mobile intervention ("agoraphobia-free") is more effective than the generic, control intervention ("stress free"). |
| Ethics approval(s) | Roehampton University Ethics Committee, 21/05/2014, ref: PSYC 14/ 117 |
| Condition | Agoraphobia/Agoraphobic anxiety |
| Intervention | Adults that self-identified with agoraphobia were randomised to the two treatment arms. Block randomisation was applied to ensure equal numbers of participants in each group (ratio 1:1). Group 1: Participants are given access to the “Agoraphobia Free” app developed by Health e-Living Partnership Ltd. (HeLP) for iOS and Android. The app involves an interactive game-based intervention utilising cognitive-behavioural techniques that target agoraphobia. Group 2: Participants are given access to a generic stress-reduction application (“Stress Free”), which does not specifically address agoraphobic symptoms. The app aims to help to lower anxiety levels through techniques such as calm breathing, differential deep muscle relaxation, self-hypnosis and meditation Participants in both groups are given access to the application for a total of 12 weeks, and complete self-reported assessments at baseline, midpoint (6 weeks) and endpoint (12 weeks) of the trial. |

| Primary outcome measure | Severity of agoraphobic and panic symptoms are measured using the Panic and Agoraphobia Scale at baseline, 6 and 12 weeks. |
| Secondary outcome measures | 1. Degree of subjective distress experienced because of agoraphobia is measured by using a single item (“How much distress have you experienced because of agoraphobia in the past week?”), which is rated from 1 (“No distress”) to 5 (“Extreme distress”) at baseline, 6 and 12 weeks 2. Completion of the intervention is measured as 1 (completion of the tasks) or 0 (non-completion of the tasks) at 6 and 12 weeks 3. Engagement with the apps is measured using app usage data (i.e. total number of times that users engaged with the app) at 6 and 12 weeks |
