Meeting the needs of parents with mental health problems and their families raises practical, professional and organisational challenges for services. SCIE’s guide, Think child, think parent, think family (2009, revised 2011)addresses these challenges, and recommends ways to overcome them. To test these recommendations, SCIE supported the implementation of the original guide in five English local authority areas (Birmingham, Lewisham, Liverpool, North Somerset and Southwark), and all five Northern Ireland health and social care trusts.
