A psychosocial intervention is described geared to the needs of carers of the long-term mentally ill, which is feasible for a busy clinical team to implement: relatives were not selected for the group by patient diagnosis or motivation and little extra staff input was required. An interactive education session at home was followed by a monthly relatives group which aimed to reduce components of expressed emotion (EE) and to alleviate burden. The group facilitators adopted a directive but non-judgemental style, and constructive coping efforts were encouraged. The intervention was effective at reducing EE and improving family relationships. The study offers a realistic model of how to offer support to people providing long-term care for the severely mentally ill.
