Plain English Summary
Background and study aims
We have found that heartbeat timing (heart rate) affects the way the brain processes fear. This is called Cardiac Control of Fear in the Brain (CCFIB). This effect is present in 75% of the population and its possible that it is linked to mental health problems. We want to find out whether more people with anxiety disorder display CCFIB compared to other type of patients. In a follow-up study, we will also find out whether CCFIB can predict how well treatments will work.
Who can participate?
Adults who currently use mental health services.
What does the study involve?
Participants are asked to complete questionnaires that gather information on their symptoms of mood and anxiety, how severe their disorder is, their quality of life, medical history, and how they see their own body (body perception). Participants also complete some computerised tasks that measure their interoceptive awareness (awareness of, for example, heartbeat, “butterflies in the stomach” or being aware of face flush) while using a finger sensor to measure their pulse.
What are the possible benefits and risks of participating?
There are no immediate benefits from taking part in this study. Although this research may not directly benefit participants, it could result in new ways of treating anxiety and other mental health symptoms in the future. There are no risks in participating in the study. Information from the study will be protected and anonymous so that people will not have access to the information about who took part or find out results of any one individual.

Scientific title
Cardiac Control of Fear in Brain: relationship to anxiety symptoms: an observational study
Acronym
CCFIB
Study hypothesis
Primary objectives are to determine whether the cardiac control of fear in the brain (CCFIB) is linked to anxiety disorder (i.e. whether a greater proportion of anxiety patients express CCFIB than other patient groups and control groups).

Topic: Mental Health; Subtopic: Anxiety; Disease: Anxiety
Intervention
Participants will first give informed consent and will then perform computerized measures of interoceptive awareness and CCFIB. CCFIB is a clinical screening tool. The usefulness of CCFIB as a clinical screening tool will be evaluated against symptom expression within a clinical population. We will examine whether CCFIB predicts treatment effectiveness. Physiological equipment is applied with participant seated, including application of finger sensors for heartbeat measurements using a pulse oximeter.
The second component of the study is a follow up study. Patients assessed within the survey, and assigned to a cognitive behavioural therapy (CBT) programme or a course of SSRI medication, will be followed up.
Updated 17/07/2015: All patients assessed within the survey will be followed up.
