Eligibility
Inclusion criteria
Inclusion criteria: 1. Above 18 years old 2. GP diagnosis of asthma 3. Taking regular preventative asthma medications, e.g. steroid, LABA 4. Attended an asthma review clinic with a medical professional (GP, respiratory clinician, practice nurse) within the last 12 months (to ensure we exclude other causes of breathlessness) 5. Self-report that asthma symptoms are not well-controlled based on a score > 25 in the self-evaluation of breathing questionnaire despite taking medication. This will be taken to indicate an underlying breathing pattern disorder. 6. Ability to stand without any assistive device for at least 20 minutes (to ensure sufficient capacity to complete the intervention) 7. Speak and understand English sufficiently well to receive the intervention.
Exclusion criteria
Exclusion criteria: 1. Dementia or other major cognitive impairment 2. BMI > 32 (as increased subcutaneous fat prevents use of breathing visualisation system) 3. Current smoker or smoked regularly within last 6 months 4. Respiratory comorbidity, including COPD, bronchiectasis, cystic fibrosis, pneumonia 5. Significant breathless from condition such as heart disease, cancer, pulmonary fibrosis 6. Any cardiorespiratory disease that requires medical intervention 7.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Breathing difficulty is measured using the Self Evaluation of Breathing Questionnaire (SEBQ) at baseline, 2 weeks and 3 months post-intervention | — |
Secondary
| Measure | Time frame |
|---|---|
| The following secondary outcome measures were assessed at baseline, 2 weeks and 3 months post-intervention (unless otherwise stated): 1. Hyperventilation symptoms are measured using the Nijmegen Questionnaire 2. Asthma control is measured using the Asthma Control Questionnaire (ACQ) 3. Asthma-related quality of life is measured using the Asthma Quality of Life Questionnaire (AQLQ) 4. Healthcare utilization and asthma exacerbations are measured using a custom questionnaire 5. Generalized anxiety and depression are measured using the Generalised Anxiety and Depression Scale (GAD-7) 6. Treatment credibility and expectancy are measured using the Credibility/Expectancy Questionnaire (CEQ) at 2 weeks post-intervention only 7. Engagement with breathing retraining is measured using a custom questionnaire at 2 weeks and 3 months post-intervention 8. Diversity and inclusion are measured using a custom Diversity and Inclusion Survey at baseline only | — |
