Carers play an essential role in the lives of people suffering from mental health problems. Caring is very often a relational activity carried out by family members. Assertive Outreach (AO) services ought to be particularly well placed to support carers, but their impact upon families is not well understood. We set out to understand the intervention of AO services from a family perspective, and in particular to explore its meaning from the perspectives of pairs of carers. Three pairs of carer-parents participated in six individual open-ended interviews.
