However, a one-way MANOVA indicated no difference in these dimensions between carers of people with BD I and II. Reflexive thematic analysis revealed five superordinate themes relating to informal caregivers' challenges, coping strategies, and the support they need. The themes were: like a roller-coaster; carer mental health; complexities of the carer role and diagnosis; how to cope; and multifaceted support. The oscillation of symptoms and complexities of the caring role increased the burden on carers and created mental health challenges, requiring carers to use various coping strategies.
