Background
The Children Service Interview was designed as a brief measure of service use related to mental health problems in Great Britain.
Method
We validated the Children’s Services Interview against medical records from a sample of 87 children, and assessed test–retest
reliability from 25 parents completing two interviews. We examined criterion validity by looking at the service use patterns
of children attending clinics for different types of disorders.
Results
The Children’s Services Interview showed high levels of face validity and moderate or better concordance with medical records
as far as contacts were recorded in the case notes. Test–retest reliability was moderate or better apart from contacts with
the voluntary sector, teachers, and the number and duration of appointments with some professionals.
Conclusion
The study suggests the Children’s Services Interview can extract moderately valid and reliable data on service use.
