The Interaction Between Asthma and Anxiety: An Interpretative Phenomenological Analysis of Young People's Experiences.

Asthma and anxiety are highly co-morbid, and their interaction leads to exacerbations for both conditions. This study explored the interplay between these two conditions from the perspective of children and adolescents. The objective was to identify potential mechanisms of interaction between asthma and anxiety, and to derive improvements for prevention and treatment. Eleven semi-structured interviews of young people (aged 11-15), who met criteria for both asthma and anxiety, were analysed using interpretative phenomenological analysis. Well-established qualitative research recommendations were followed to promote credibility and rigour in the findings. Eight themes emerged that were organised in three domains: (i) asthma affecting anxiety by inhibiting coping activities or developmental tasks and by triggering unhelpful thinking and behaviour; (ii) anxiety affecting asthma by impairing self-care and triggering hyperventilation; (iii) interactions between asthma and anxiety, including self-perpetuating feedback cycles and symptom confusion. The proposed mechanisms could help tailor cognitive-behavioural interventions to reduce anxiety and asthma complications.
