Plain English Summary

Background and study aims
Depression affects people in different ways and can cause a wide variety of symptoms. They range from lasting feelings of unhappiness and hopelessness to losing interest in the things you used to enjoy and feeling very tearful. Many people with depression also have symptoms of anxiety. There can be physical symptoms too, such as feeling constantly tired, sleeping badly, having no appetite or sex drive, and various aches and pains.
Depression in teenagers knocks normal development off course and disrupts family relationships. Even after treatment, many young people are left with depressive symptoms, so we need more treatments for this group who suffer greatly. We have developed a new treatment; Mindfulness for Adolescents and their Carers (MAC), which helps young people and their parents to learn to recognise unhelpful patterns of thoughts, feelings and behaviours, and to find alternative ways to cope with distress. Our earlier work shows that young people and their parents wanted to attend MAC sessions, which they found helpful. Young people's depressive symptoms reduced afterwards.

Before we can test whether MAC works and is value for money, we need to answer three questions.
1. Who should be trained to deliver MAC, and how should they be trained?
2. What does usual treatment look like for this group of young people?
3. What is the best way to recruit young people and their carers to trial of MAC?

Who can participate?
1. Young people aged 14-17 with a primary clinical diagnosis of depression who have had initial treatment at Child and Adolescent Mental Health Services (CAMHS) and are not fully recovered or who have relapsed quickly following discharge, and their parent(s) / carer(s)
2. CAMHS practitioners at band 6 or above with a personal mindfulness practice and level 1 training in mindfulness-based intervention delivery, or equivalent experience

What does the study involve?
1. We will develop a training programme for potential group leaders who will attend 4 days of training prior to delivering MAC under supervision
2. We will interview key managers and practitioners in CAMHS about the depression treatment pathway and carry out a detail study of records to understand usual treatment for this group of young people.
3. We will run two groups of 10 young people (with a parallel group for their parents/ carers) to establish whether we can recruit and retain effectively and to study which questionnaires work best for a future randomised controlled trial. There are 9 weekly workshops, each lasting 1.5 hours. Workshops will be held using NHS approved video conferencing software that can be accessed securely from participants’ homes using a laptop/computer or smart phone
4. We will ask both young people and their parent or carer to fill in a set of questionnaires at three different times, when they join the study at baseline and then 4 and 9 months later. The questions will help us to measure if there have been any changes in the way participants are feeling. These questions will be completed on a secure online website which participants can access via a computer or smart phone. These questionnaires are likely to take about 90 minutes to complete.

What are the possible benefits and risks of participating?
The young people and parents who participate will get access to a novel treatment that shows promise in young people and is established in adults.
The practitioners attending training will develop new skills and a deeper understanding of mindfulness.
All participants will need to complete questionnaires and some will discuss their experiences in person. This will demand their time, and some of the topics may be sensitive for some people. The researchers will do their utmost to avoid distress and anyone who becomes distressed will be signposted to support.
Mindfulness techniques can increase anxiety or lead to distress in some people. Group leaders will be trained to identify and support any young people or parents who experience such distress and support will be provided.

Study information

Scientific title

A combined mindfulness-based approach for adolescent non-responders to first-line treatments of depression and their carers: establishing feasibility of implementation and delivery



Study hypothesis

This proposal addresses four important uncertainties and will:
1. Develop the training programme for therapists, which may need to differ in emphasis depending on whether they come from child mental health or mindfulness backgrounds
2. Describe current care pathways (to aid recruitment) and develop an understanding of what Treatment As Usual (TAU; probable comparator) comprises for the young people we want to recruit
3. Test the process for identifying young people and their carers and see how many start and finish MAC, so we better understand how many clinics we need to work with to test MAC in a definitive trial
4. Test the acceptability of asking for blood and saliva samples for the future study of how MAC works

Patient information sheet

Potential therapists will attend 4 days of training to be delivered remotely to familiarise them with the manual – they will then contribute to the delivery of MBCT to two groups of 10 young people or the parallel groups for their carers

‘Mindfulness for Adolescents and Carers’ (MAC) is delivered to a group of up to 10 young people at a time, there are 9 weekly workshops, each lasting 1.5 hours. Workshops will be held using NHS approved video conferencing software that can be accessed securely from participants’ homes using a laptop/computer or smart phone. Their parent or carer are invited to attend a parallel but separate workshop with other carers to work through similar materials. Both young people and their parent or carer fill in a set of questionnaires at three different times, when they join the study at baseline and then 4 and 9 months later.

Primary outcome measure

All outcomes are measured at baseline and then 4 and 9 months later. The following constructs will be measured in young people using the following measures:
1. Depression using RCADS
2. Quality of Life using CHU-9D
3. Family dynamics using Score-15
4. Mindfulness using CAMM
5. Self-compassion using SCS-SF
6. Emotional Regulation using ERQ
7. Decentering using EQ (Decentering Scale)
8. Rumination using CRSQ

And in parents/carers:
9. Depression using GAD and PHQ-9
10. Quality of Life using EQ-5D
11. Family dynamics using Score-15
12. Mindfulness using FFMQ-SF
13. Self-compassion using SCS-SF
14. Emotional Regulation using ERQ
15. Decentering using EQ (Decentering Scale)
16. Rumination using RRS

Secondary outcome measures

There are no secondary outcome measures
