Scientific title

Factors influencing the outcome of children attending Croydon Child and Adolescent Mental Health Services (CAMHS): a multicentre cohort study


Croydon CAMHS Outcome Project

Study hypothesis

This project will focus on the effectiveness of Child and Adolescent Mental Health Services (CAMHS). It will evaluate a methodology for assessing the effectiveness of attendance at CAMHS by judging clinical outcome measures against normative data from national epidemiological studies. It will also identify factors predicting the outcome of children attending CAMHS with the aim of generating an empirically derived prognostic index. It will also assess the feasibility of the adoption of a standardized diagnostic assessment into routine practice. It will study the attitudes of CAMHS clinicians toward routine outcome monitoring and how these change over the course of the project. Finally, it will compare the rates of public sector service use over 18 months by CAMHS attenders as compared with a community sample of untreated children with similar psychopathology from a national study with a view to planning a more detailed cost-effectiveness study in the longer term.

1. To evaluate the utility of the SDQ "added value" computer algorithm as a tool to allow clinics to measure their performance with that of untreated children in the community
2. To explore staff perceptions, about the use of a standardized diagnostic assessment and routine outcome monitoring
3. To gather preliminary data, to establish whether an in depth study of cost effectiveness is feasible
4. To identify factors, influencing the outcome of children attending Croydon CAMHS in order to generate an empirically based measure of case complexity

There was no treatment arm – children were assessed at baseline using the Development and Well-being Assessment which includes a brief measure call the SDQ (completed by parents) prior to assessment, and a brief in house questionnaire completed by the assessing clinician about what difficulties the child had, their level of function according to the CGAS, and was their assessment completed.

Every six months for two subsequent years the parents completed an SDQ, while the clinicians reported on how they perceived the child’s difficulties, the CGAS and what interventions had happened in the previous six months – if the child's was discharged, clinician follow up ceased (for obvious reasons) but parental follow up did not – we are just chasing the final follow ups for the final patients and data collection will close at the end of this month.

Follow-up length: 26 months
Study entry: single randomisation only

Primary outcome measure

SDQ total difficulties and impact scores, according to parents at six monthly intervals.

Secondary outcome measures

1. CGAS scores at 6 monthly intervals
2. Parental rating of whether coming to the clinic has changed the child's difficulties according to the follow up SDQ at six monthly intervals
2. The SDQ "added value", as produced by the computer algorithm

Participant inclusion criteria

1. Subsequent referrals accepted to the waiting list of two district tier 2 - 3 CAMHS services
2. Aged between 5 - 10 years and 9 months over 2 years and 2 months

Participant type


Age group




Target number of participants

Planned sample size: 300; UK sample size: 300

Participant exclusion criteria

1. Younger than five or older than 10 years and 9 months at the time of they are accepted onto the waiting list
2. Child is looked after by their local authority, because of the difficulty of parental responsibility changing during the course of the study and because of the difficulty in finding informants that know the child well enough
3. The parent has insufficient English to complete the questionnaires
4. Emergency and paediatric liaison referrals because of the difficulty in gaining consent and completing the base line assessment between referral and first assessment
