Plain English Summary

Background and study aims
Urticaria and angioedema are terms used to describe hives and swellings, which can be very distressing, recurrent and sometimes difficult to treat. While the exact cause of this condition is not known, it is known that a specialised cell called the ‘mast cell’ is important. Mast cells can be affected by many factors, one of which might be chemical signals released when the body is under stress. These signals might make the condition worse. It has been suggested that by controlling how the body responds to stress, mast cell activity and therefore hives and swelling can be limited. There is growing evidence to support the potential benefits of attention based training (ABT) on psychological and physiological wellbeing. Therefore, the aim of this study is to find out whether ABT could help to improve the wellbeing of urticaria patients attending St James’s’ hospital. Based on the results of the study, the researchers hope to develop an ABT programme that can be used to help reduce stress and improve wellbeing among urticaria patients throughout Ireland.

Who can participate?
Patients aged over 18 with chronic spontaneous urticaria that is poorly controlled

What does the study involve?
The study involves a preliminary appointment with a researcher where participants fill out questionnaires and have a blood sample taken. They will then attend eight sessions of attention based training. These sessions aim to teach skills in meditation. It is hoped that these skills might improve symptoms of urticaria. Participants then attend a follow-up appointment with a researcher where they again complete questionnaires and have a blood sample taken.

What are the possible benefits and risks of participating?
The researchers do not anticipate any risks from taking part. There will be no direct benefit from taking part although it is hoped that participants might find the skills taught in the programme useful and informative.

Where is the study run from?
St James's Hospital (Ireland)

When is the study starting and how long is it expected to run for?

Chronic spontaneous urticaria and angioedema


This study has one arm, which is attendance at an attention-based training programme based on meditation for patients with chronic spontaneous urticaria. The attention-based training programme consists of 8 x 90-minute sessions that are delivered by a qualified psychologist.

Intervention type



Drug names

Primary outcome measure

1. Barriers to implementation of the intervention identified through convergent interviewing techniques at baseline and 1-week post completion of the intervention
2. Recruitment and retention of participants measured by recording participant attendance throughout the intervention over an 8-week period
3. Adherence to daily practice using individual biofeedback tools (HeartMath software) throughout the intervention over an 8- week period
4. Feasibility of collecting outcome assessment data measured by assessing the return of data from participants at baseline and 1-week post completion of the intervention
5. Qualitative assessment of participant experiences of the programme collected via interview 1-week post completion of the intervention

Secondary outcome measures

1. Perceived individual symptoms measured using the urticaria control test (UCT) at baseline, 1 week before and 1 week after completion of the ABT programme
2. Depression, anxiety and stress measured using the depression-anxiety-stress score (DASS) at baseline and post 8-week ABT programme
3. Bio-psycho-social health measured using the PERMA-profiler at baseline, 1 week before and 1 week after completion of the ABT programme
4. Traits associated with sustained meditation practice (attention, observational skills, non-reactivity and non-judgemental skills) measured using the five-facet mindfulness questionnaire (FFMQ) at baseline, 1 week before and 1 week after completion of the ABT programme
