Plain English Summary
Background and study aims
Depression is a mental health condition where a person feels persistently sad and low in mood for two weeks or more. It affects people in different ways. Sufferers can feel hopeless, anxious and lose interest in doing things they used to enjoy. It can also lead to problems with sleeping, feeling constantly tired, a loss of appetite and a low sex drive. In the most extreme cases, it can result in a person harming themselves or attempting to take their own life (suicide). Depression in young people is common and can result in poor academic achievement and feeling suicidal. Behavioural activation (BA) therapy is a treatment for depression. When people are depressed they tend to avoid others and isolate themselves which often serves to make them feel worse. BA works by encouraging people to do activities that are known to improve mood. Recent research has suggested that BA therapy may be useful as a treatment for depression in young people but, to date, there have been no published studies showing this in the UK. Here, we want to test if it is possible to use BA therapy to treat young people attending UK Child and Adolescent Mental Health Services (CAMHS). We also want to know if such a treatment would be acceptable to this age group.
Who can participate?
Young people, aged 12 to 17 years, with a diagnosis of major depressive disorder and attending UK CAMHS.
What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 receive 8 weeks of BA therapy. Those in group 2 receive their usual treatment for depression. A series of questionnaires that explore each participants mood and feelings are filled in by them at the beginning of the study and then 3 months later. Those participants in the BA therapy group, and the clinicians giving the treatment, are also offered an interview to discuss their feelings and experiences of the therapy. Participants are asked to fill in another series of questionnaires over the phone six months after they started the study.
What are the possible benefits and risks of participating?
There may be risks and burdens to taking part; the treatment may not be as good as the usual treatment, harm may be caused to the participants and the participants will be asked to attend interviews that they would not normally be asked to attend. These risks are countered by the opportunity for young people to access a previously unavailable treatment, to receive an more in-depth assessment and longer follow-up than normal. In addition, Child and Adolescent Mental Health Service capacity may be improved by the use of a treatment that is suitable for less experienced staff to deliver.
Where is the study run from?
This study is being run by Durham University (UK) and takes place in CAMH sites in the UK.
When is the study starting and how long is it expected to run for?
March 2015 to September 2016
Who is funding the study?
Tees, Esk and Wear Valleys NHS Foundation Trust (UK)

Major Depressive Disorder
Participants are randomly allocated to one of two groups. Behavioural activation therapy is the active arm and treatment as usual is the control arm. Individual randomisation was used via remote telephone randomisation. The randomisation list is created by a statistician who used blocked randomisation (with stratification according to Tier of care and depression severity). The assessor was not involved in the randomisation process.
In the behavioural activation (BA) arm participants receive eight sessions of a brief BA treatment following a structured treatment manual. In addition, participants receive any other non-psychological treatment deemed necessary by their clinician.
In the treatment as usual (TAU) arm participants receiveany treatment deemed necessary by their clinician. Details of the treatment provided were obtained from the Trust’s patient electronic records system.
The total duration of treatment is recorded but not restricted (so varied between participants).
Participants are followed up at three and six months (and a selection of those attend a qualitative interview which may have occurred during their three month follow-up or at a later date if their treatment had not been completed by that stage).
Primary outcome measures
The feasibility and acceptability of the study will be assessed by quantifying the flow of patients (in terms of eligibility, recruitment, adherence and attrition rates).
Secondary outcome measures
Current outcome measures as of 20/10/2017:
1. Assessor-rated depression status (DSM major depressive disorder or not) using the K-SADS-PL (structured diagnostic interview in person with participant and parent/carer [in some cases]) at baseline and three month follow-up
2. Young person self-report depression severity using the MFQ-C (validated questionnaire) at baseline, three and six month follow-up (baseline and three month follow-up were in person and six month over the telephone)
3. Parental report of their young person’s depression severity using the MFQ-P (validated questionnaire for parents/carers of some participants) at baseline, three and six month follow-up (baseline and three month follow-up were in person and six month over the telephone)
4. Self-reported self-esteem using the RSE (validated questionnaire) at baseline, three and six month follow-up (baseline and three month follow-up in person and six month over the telephone).
Assessor-rated level of functioning using the CGAS (part of the K-SADS) as above at baseline and three-month follow-up
5. Self-reported activation using the BADS (questionnaire not validated in young people) used for descriptive purposes at baseline, three and six month follow-up (baseline and three month follow-up were in person and six month over the telephone).
6. Self-reported satisfaction with study and intervention using the end of study survey (designed specifically for this study for young people and parents/carers [in some cases]) at three month follow-up.
Previous outcome measures:
1. The feasibility and acceptability of the Behavioural Activation intervention will be evaluated via survey and qualitative interview data gathered from participants and clinicians on receiving and implementing the intervention.
2. The feasibility and acceptability of the study design and procedures will be evaluated via survey data from participants and parents/carers (in both arms of the study).
3. To obtain stable estimates of the variance in the outcome measures; score on Mood and Feelings questionnaire, the Behavioral Activation for Depression Scale Short Form and Rosenberg Self-esteem measure will be used.
4. To describe whether participants still meet the Kiddie-SADS-Present and Lifetime version DSM-IV diagnosis of depression (or are in remission) and also to comment upon the use of Routine Outcome Measures in treatment sessions. This information will be used to explore the differences between groups.

Results and Publications
Publication and dissemination plan
It is intended that two papers will be submitted to peer-reviewed academic journals from this trial. A short report detailing the recruitment and participant flow within the trial and a longer more in-depth qualitative paper focusing on the intervention. I intend to publish by 20/10/2018. I also hope to present my work at a relevant academic conference in 2018.
A lay summary will be sent to participants and their families in both arms of the trial. A similar summary will also be sent to staff who participated in the trial and a PowerPoint presentation will be offered to all participating CAMHS teams to discuss the implications for clinical practice.
