The multi-systemic and multicomponent family intervention for 5−12 year-old children with neuropsychiatric symptoms is based on the intervention program developed by the Health department of the Social Insurance Institution of Finland. In order to incorporate the best current practices and delivery formats, an independent expert panel of child psychiatry specialists from the Finnish University Hospitals was recruited in intervention development. Intervention feasibility and acceptability were further assessed by piloting work. At the present project, time-limited services (12 to 24 months) are provided in two different arms (i.e. separate intervention programs) referred to as LAKU and Etä-LAKU family intervention programs. Aims of the family intervention are to help children to strengthen their socio-emotional skills at home and in everyday life settings, help children and families to cope with their experiences, and strengthen interpersonal interaction among family members to overcome possibly difficult life situations, thoughts and emotions.
