Plain English Summary
Background and study aims
An online, parent-led, therapist-support intervention called OSI (Online Support and Intervention for child anxiety) was previously co-designed. Previous research has found OSI to be clinically effective, cost-effective and acceptable to clinicians and families. OSI has now been adapted to meet the needs of autistic children with anxiety problems and their families. This adapted version of OSI is called OSI-A. The STAR-CAT study will test whether OSI-A can make treatment for anxiety problems among autistic children more accessible without compromising children’s outcomes.
Who can participate?
Children aged 5-12 years old, with either diagnosed autism or suspected autism, about to receive treatment for anxiety problems
What does the study involve?
The study involves being randomly allocated to either OSI-A or Treatment as Usual (TAU) after completing questionnaires at the time of enrollment. These questionnaires will be repeated at 24 weeks and 48 weeks post-randomisation. Please note that if the child does not have an autism diagnosis, they will need to complete 'consent to screen' and a questionnaire before enrolment to check eligibility for the STAR-CAT study.
What are the possible benefits and risks of participating?
Benefit:
Children taking part in this study will all receive treatment. Those in the OSI-A arm will receive treatment from therapists who will have received training from experts in child anxiety treatments (via an e-learning platform) and will have access to a novel, online intervention that may bring efficiencies for families.
Time burden: Participants will be required to complete more measures than they would in usual clinical practice. Families will receive £10 for each completed follow-up questionnaire to compensate for the extra time spent on research-related questionnaires within this trial.
Novel treatment delivery: Families in the OSI-A arm of the trial will receive an adapted version of an established online treatment but the online version has not yet been systematically evaluated. As such we cannot be sure what the outcome will be.
Audio recordings: Audio recordings will be made during qualitative interviews and some participants may feel cautious about this.

Scientific title | Clinical and cost-effectiveness of adapted online parent-led treatment compared to treatment as usual for autistic children with anxiety problems in clinical services: A randomised controlled trial. |
Study acronym | STAR-CAT |
Study hypothesis | To evaluate the parent-reported clinical effectiveness of a brief parent-led cognitive behavioural treatment (CBT) delivered by the OSI-A platform with therapist support (OSI-A + therapist support) for the treatment of anxiety in autistic children compared to ‘treatment as usual’ (TAU) in child mental health services. |

Condition | Anxiety problems in autistic children aged 5-12 |
Intervention | This is a two-arm, multi-site, randomised controlled non-inferiority trial, with a nested pilot trial, to evaluate the clinical and cost-effectiveness of a brief parent-led cognitive behavioural treatment (CBT) delivered by the Online Support and Intervention for autistic children (OSI-A) with therapist support compared to treatment as usual in child mental health services and to explore parent, child, and therapists' experiences. Randomisation will be performed using a fully validated randomisation system Sortition® with a non-deterministic minimisation algorithm to ensure child age (<=8; >8), gender, service type (school-based, specialist neurodevelopment service, or other), baseline anxiety-associated interference (measured by CAIS-P <=25; >25), and the status of autism (likely to be autistic; confirmed autistic) is balanced across the two groups. Participating families will be randomised to either OSI-A with therapist support or to usual treatment within child mental health services to establish whether OSI-A plus therapist support can reduce therapist time without compromising outcomes for autistic children with anxiety problems. Participating clinics offering child mental health services will receive training on trial procedures, including identifying eligible participants. They will also be given training on how to use the OSI-A platform. Participating families will be identified by their clinical teams. If the child has not yet received an autism diagnosis, clinicians need to ensure that the possibility of autism has been discussed with families before this study is introduced to the family. Clinical teams will follow their usual procedures to identify the child’s primary presenting problem. Where the clinical teams identify the child has an autism diagnosis, or is considered to be likely to meet criteria for an autism diagnosis, and has a primary anxiety problem, they will be considered to be potentially eligible for the trial. Potentially eligible families will be provided information about the study by their clinician and, if interested, will provide verbal consent for the clinician to confirm that the study inclusion criteria are met (and exclusion criteria are not) and to send the family a link to the Patient Information Sheet and Informed Consent Form. If the child does not have an autism diagnosis, then the family will be required to complete the SCQ online to confirm eligibility. The clinician will provide parents/caregivers with an information pack (via online link or paper) containing information sheets about the study for the parent/caregiver and the child (age-appropriate and in various formats, e.g., video). The information sheets will provide further information about the study and what would be expected of the participants alongside contact details for the study team (email and phone number) so that they can be contacted to answer any questions. The family will have the opportunity to complete online consent to the main study (if the child has a confirmed autism diagnosis) or consent to screen (if SCQ is required to confirm eligibility). Once the SCQ is complete, and the score confirms eligibility, the family will be able to consent to the main study. If the SCQ indicates that they are ineligible, the family will be informed, and the treating clinician will be asked to provide alternative treatment. The research team will be informed of the results, using the family’s unique trial ID number, which they will use to follow up with the therapist to ensure alternative treatment has been arranged. The screening data (including SCQ score) will be retained to monitor recruitment and reasons for ineligibility to ensure parity in access. The parents/caregivers who consent to the main study will then be asked to complete online self-report baseline assessments (all questionnaires). At the end of the questionnaires, the parent/caregiver can indicate whether the child would like to provide (optional) assent to take part and complete the child self-report questionnaires. Participants will be randomised within 1 month of expression of interest and allocated to the intervention arm or treatment as usual (TAU). Families allocated to the intervention arm will be delivered OSI-A + therapist support by a member of the clinical team. OSI-A incorporates routine outcome measures for clinical purposes, but these measures are also available to the research team through the OSI (pseudo-anonymised) researcher portal. Families allocated to TAU will receive the treatment their clinical team would usually offer, and information will be gathered on the nature of this treatment through therapist logs. Participating parents will be sent a link to complete post-treatment and follow-up assessments (questionnaires) online 24 and 48 weeks after randomisation. Once parents have completed their questionnaires, children who have assented will have the opportunity to complete their self-report questionnaires. Qualitative interviews will be conducted with a subgroup of parents, children, and clinicians from both arms (n= 45-60), purposively sampled based on demographics and treatment outcomes, to explore clinicians', parents’, and children’s experiences of treating child anxiety. Clinicians will be provided with an information sheet for this part of the study, and those who participate in these interviews will provide consent at the beginning of the interview. Additionally, multimodal data will be collected from up to 50 children invited from the wider trial population. Children will be able to choose from a creative ‘menu’ of participation modes, co-designed with children, parents, and clinicians, building on established methods. This menu will offer a range of modalities (e.g., a digital pinboard for images and memes) for children to share their experiences of anxiety. Children will be invited to contribute at two timepoints: pre-intervention and post-intervention. Parents will have the opportunity to provide optional consent for their child to take part in this activity when they sign the main consent form. |
