Plain English Summary

Background and study aims
Depression is a major cause of poor health and social disability, affecting children of all ages but peaking in adolescence. Common symptoms include persistent sadness or irritability, loss of interest in activities and people, and fatigue. Providing therapy at the earliest opportunity is essential. Child and Adolescent Mental Health Services (CAMHS) offer interventions for depression; however, due to increased demand and limited resources, waiting lists are long and entry thresholds are high. This creates gaps between treatment provision and need, with resources often prioritised for severe and complex presentations. Young people with mild-to-moderate depression often do not meet the threshold criteria for CAMHS entry. Staff trained to provide mental health support in schools and charities are limited in numbers and many non-specific, supportive interventions are available but may not be evidence-based or may be used to contain depression rather than treat it.

Behavioural Activation (BA), a brief psychological intervention, is recommended for adults with depression. BA's premise is that engaging in meaningful, purposeful, and rewarding activities can lift people's mood, energise them and restore their interest and pleasure in day-to-day life. BA with adults has been successfully delivered by non-specialists in the community and requires fewer sessions and shorter training than other psychological therapies, such as cognitive therapy. BA has shown promising results for young people in small research projects when delivered in specialist clinics.

The current study is a large randomised controlled trial (RCT) comparing BA to usual care for treating mild-to-moderate depression in young people (aged 12 to 18 years) within the NHS, schools, and third sector organisations such as charities. The RCT, along with embedded phenomenological and ethnographic studies, will examine the clinical and cost-effectiveness of BA and assess its acceptability from the perspectives of those who receive it and those who deliver it.

Who can participate?
Young people aged 12 to 18 years who experience mild-to-moderate depression. This means that they struggle with low mood or persistent irritability and have lost interest and pleasure in day-to-day life. Other symptoms include: not being able to concentrate, pay attention, or make decisions; they may feel guilty or hopeless and think of death or self-harm; they may have problems with their sleep or appetite; they may feel either sluggish and slowed down, or agitated and on edge; they may have no energy and feel tired all the time.

Professionals who support the participating young people will be invited for an interview about their experiences.

What does the study involve?
Eligible young people who agree to participate in the study will sign a consent/assent form (alongside consent from a parent/guardian if applicable) and then be invited to complete questionnaires about their demographics, anxiety and depression symptoms, and their use of health resources and services.

Young people will be randomly offered either BA or usual care, which is what they would be usually offered for mild-to-moderate depression if BA were not available. They will have an equal chance of being in either group (like tossing a coin). Participants and researchers will not have a choice in the treatment given.

Professionals based within schools and young people’s charities will support the participating young people. Some sessions will be recorded or observed by a member of the research team to enable them to see how treatments are delivered in different participating sites.

After 6 and 12 months, participants will be invited to complete the same questionnaires as at the start of the study, with the exception of the demographics and with the addition of the a questionnaire on their experience of staff interactions. At the 6-month follow-up session, 20% of participants will be invited to an interview with a member of the research team about their experiences.

All professionals who supported the young participants will also be invited to an interview about their experiences.

What are the possible benefits and risks of participating?
Professionals in the participating sites will receive training in BA with the view of making a meaningful change in the young people's low mood/depression. Our ambition is to maximise the skills of professionals who work with young people and enable them to effectively support those who struggle with low mood/depression. BA can potentially be embedded into care pathways within schools and community organisations that strive to support young people’s mental health.

Through participating in this study, young people will be offered an assessment and follow-up support (either BA or usual care) that is expected to help with their low mood/depression. We cannot tell before we complete the study whether BA or usual care are effective and for whom, but all participants will have a better understanding of depression and its treatments through their involvement with the study. Young people will be followed up over the course of 12 months during which there will be opportunities to signpost them to available sources of help beyond this research if needed. Through their participation in this study, young people will make a contribution to the wider body of knowledge about depression and its treatments, and to the community of practice that supports their peers who struggle with low mood/depression.

Completing questionnaires and an interview as part of this study and attending sessions as part of BA or usual care will demand young people’s time and energy. The researchers and professionals who support young people will be flexible in the delivery to suit a young person’s circumstances, for example, by changing the frequency of sessions or breaking up the questionnaires and interviews into smaller chunks. Young people will always have the option to withdraw from the study if they no longer wish to participate without giving any reason.

Taking part in this research may bring up issues or risks that the young people were unaware of until then. The young people participating in this study will be monitored for any worsening of their symptoms or risk so that they can be directed to additional help if necessary. We will always ask permission from the parent/guardian (where applicable) and the young person to liaise with the relevant support services if these are needed (e.g. social care or mental health services); if the level of risk warrants it, we may directly contact the relevant services.

Where is the study run from?

Scientific titleCommunity-Based Behavioural Activation Training (ComBAT) for Depression in Adolescents: Randomised Controlled Trial (RCT) with Economic and Process Evaluations
Study acronymComBAT RCT
Study hypothesis1. Behavioural Activation for adolescents with mild-to-moderate depression is more effective and more cost-effective than usual care
2. Behavioural Activation is received well by adolescents with mild-to-moderate depression and is delivered with fidelity by professionals who support those adolescents
Ethics approval(s)Approved 10/07/2022, North East - Newcastle & North Tyneside 1 Research Ethics Committee (NHSBT Newcastle Blood Donor Centre, Holland Drive, Newcastle upon Tyne, NE2 4NQ, UK; +44 (0)203 443 6294; newcastlenorthtyneside1.rec@hra.nhs.uk), ref:22/NE/0100
ConditionMild-to-moderate depression/low mood
InterventionArm 1 - Intervention (Behavioural Activation):
All participants randomised to the intervention arm will be offered Behavioural Activation (BA). This will comprise 5 modules, delivered in up to 8 weekly sessions lasting up to 40 minutes. Sessions will be delivered by professionals from schools, third sector organisations or child and adolescent mental health services (CAMHS). BA encourages young people to engage with meaningful, purposeful and rewarding activities that can lift their mood, energise them and re-instate their interest and pleasure in life. The first step is to identify activities that are aligned with areas of their lives that are important to them and then schedule day-to-day activities that fulfil different purposes: some are done for pleasure, others are routine tasks and others are building blocks towards a bigger project or aspiration. As part of BA, young people also learn problem solving techniques, methods to reduce avoidance and to prevent relapse.

Arm 2 - Comparator (Usual Care):
Those randomised to the comparator arm will receive the usual care offered for those with mild-to-moderate low mood in the service from which they have been recruited. This may include no intervention, signposting to alternative sources of support, general discussion, supportive counselling, relaxation, recreation groups, guided self-help or psychological therapies including CBT and IPT. The usual care delivered in the comparator arm cannot be an intervention based upon Behavioural Activation. Usual care will be provided by professionals based within the services responsible for recruitment (i.e. schools, third sector organisations, child and adolescent mental health services (CAMHS)). We will record and monitor what usual care means for each young person recruited into the study.

Randomisation:
We will use simple randomisation with participants randomised on a 1:1 ratio to either BA or usual care. Randomisation will be implemented using a web-based system designed and developed by the data management team at York Trials Unit (YTU). The allocation sequence will be generated by a YTU statistician and embedded into the randomisation system.

Assessments:
Young people:
Baseline: Demographics, Revised Children’s Anxiety and Depression Scale (RCADS) – Brief Version (25 items), Children’s Depression Rating Scale-Revised (CDRS-R), Behavioural Activation for Depression Scale-Short Form (BADS-SF), Child Health Utility-9 Dimensions (CHU-9D), and Resource Utilisation Questionnaire for Adolescents (RUQ-A).
6 months: Revised Children’s Anxiety and Depression Scale (RCADS) – Brief Version (25 items), Children’s Depression Rating Scale-Revised (CDRS-R), Behavioural Activation for Depression Scale-Short Form (BADS-SF), Child Health Utility-9 Dimensions (CHU-9D), Resource Utilisation Questionnaire for Adolescents (RUQ-A), and Aspects of Care Questionnaire (ASQ). 20% of participants (across both arms) will be invited to take part in a qualitative interview about their experiences.
12 months: Revised Children’s Anxiety and Depression Scale (RCADS) – Brief Version (25 items), Children’s Depression Rating Scale-Revised (CDRS-R), Behavioural Activation for Depression Scale-Short Form (BADS-SF), Child Health Utility-9 Dimensions (CHU-9D), Resource Utilisation Questionnaire for Adolescents (RUQ-A), and Aspects of Care Questionnaire (ASQ).
