Plain English Summary

Background and study aims
Anxiety problems are common among primary-school aged children, but very few children who experience problems with anxiety receive professional support. We have worked with children, parents/carers, school staff and others to develop a new way of identifying and supporting children with anxiety problems through primary schools. We now want to compare this new approach to existing, usual school practice. In this study, we will compare children’s outcomes in schools that do and do not receive our procedures for identification-to-intervention.

Who can participate?
Children in year 4 (aged 8-9) in participating classes in participating schools

What does the study involve?
Children, parents/carers and class teachers will be invited to complete initial questionnaires, and we will also collect information about children from school records. Schools will then be randomly allocated to either 'feedback and intervention' or 'usual school practice'.

Families in schools allocated to 'feedback and intervention' group will receive feedback on whether responses to a short initial questionnaire completed by parents suggest their child may be or is unlikely to be experiencing difficulties with anxiety. Where responses suggest a child may be experiencing difficulties with anxiety, parents will be offered a brief, therapist supported online intervention. The intervention will also be made available to all participating families in these schools, regardless of initial questionnaire responses.

Families in schools allocated to usual school practice' will continue to receive any usual support available in their school and elsewhere, and at the end of study (2 years later) they will be offered written (PDF) versions of the intervention.

Children, parents/carers and class teachers in all schools will be asked to complete questionnaires again after4 months, 12 months and 24 months.

What are the possible benefits and risks of participating?
Families who take part will all be offered either a brief online and telephone support intervention as part of the study, or a written (PDF) version of the online intervention at the end of the study.

Participants will need to spend some time completing questionnaires. Although we work hard to try to make sure the questions are as acceptable as possible, some questions address thoughts and feelings that some participants may find upsetting.

Scientific titleIdentifying Child Anxiety Through Schools – identification to intervention (iCATSi2i): a cluster randomised controlled trial
Study acronymiCATSi2i
Study hypothesisPrimary objective:
To compare outcomes for children (aged 8-9) who screen positive at baseline in schools allocated to ‘feedback and intervention’ versus ‘usual school practice’

Secondary objectives:
1. To estimate the cost-effectiveness of ‘feedback and intervention’, extrapolating results beyond the end of the trial duration
2. To evaluate experiences of procedures for identification-feedback-intervention to inform an integrated process evaluation
3. To compare outcomes for the total population of Year 4 children (aged 8-9) in participating classes in schools allocated to ‘feedback and intervention’ versus ‘usual school practice’

ConditionAnxiety problems
InterventionCurrent intervention as of 11/04/2022:
Children in Year 4 (aged 8-9 years) in participating classes and their parent/carer and class teacher will be invited to take part. Assessments will be completed at baseline (before randomisation), and 4 months, 12 months and 24 months post-randomisation. Our target population is children who screen positive (score above the cut-off on the 2-item parent-report child anxiety questionnaire) at baseline, but we will also follow-up all recruited children (total population).

The trial will include an internal pilot. We will recruit schools in two cohorts one year apart (pilot phase: 30 schools; phase 2: 50 schools). The decision to continue beyond the pilot phase will be taken by the funder, with advice from the independent programme steering committee.

After baseline assessments are complete in a cohort of schools, schools will be randomised by an independent statistician to either 'feedback and intervention' or 'usual school practice' in a 1:1 ratio stratified according to school demographic information. The statistician will pass the allocation to the study team who will notify schools and families.

'Feedback and intervention' arm:
i) Feedback
Parents/carers who complete the baseline 2-item child anxiety questionnaire will receive a written feedback letter that informs them whether their responses indicate their child may be experiencing difficulties with anxiety or is unlikely to be experiencing difficulties with anxiety. The letter also provides information about the intervention programme.   Where a child 'screens positive', the parent/carer has a short feedback call with a study Wellbeing Practitioner or Clinical Psychologist, and is offered the intervention programme. Where a child 'screens negative', the feedback letter will invite parents/carers to contact the research team if they may be interested in taking part in the intervention and/or would like to discuss this option. 

The intervention programme will also be made available for all families in the 'Feedback and intervention' arm, including those where parents/carers did not give initial opt-in consent/complete baseline measures.

ii) Lesson on recognising and managing anxiety and resources for school staff
The research team and/or school staff will deliver a whole-class lesson on recognising and managing anxiety, and we will share information about the intervention and skills and strategies parents learn in the intervention with school staff. 

iii) Online Support and Intervention for child anxiety (OSI)
Parents/carers work through seven online modules. Each module is supported by a short weekly telephone session with a therapist, and a follow-up telephone review about 4 weeks later.  There is also an accompanying app for the child that is a game for mobile phones/tablets. 

Schools will continue to provide any usual support, and families will be free to continue to seek and/or receive any other additional support from school and/or other service providers throughout the trial. 

Usual school practice arm:
Schools will continue to provide any usual support, and families will be free to continue to seek and/or receive any other additional support from school and/or other service providers throughout the trial. After the 24-month assessment, families will be offered a written (PDF) version of the content of the online intervention.
