Plain English Summary

Background and study aims
One in eight women suffers from depression during pregnancy. Depression affects the mother, infant and family, so it is important to offer effective treatments that meet their needs. Currently CBT is the only widely available NHS talking treatment. Mothers in PPI groups have asked for greater treatment choice. IPC, a brief individual therapy, has important advantages over CBT because it focuses on issues relevant to women during pregnancy. These include: key relationship problems, changes in role and previous loss (e.g. miscarriage) and can involve partners. Women may be more likely to complete IPC and it may therefore work better than CBT. The aim of this study is to test whether it is possible to recruit, randomize and offer talking therapy (Interpersonal Counselling (IPC) or brief Cognitive Behavioural Therapy (CBT)) to women with depression in pregnancy, to inform whether a large trial comparing these treatments is possible.

Who can participate?
Women between 10 and 20 weeks of pregnancy who have been screened as having depression using both the EPDS and CIS-R screening tools, identified through midwife booking clinics and at ultrasound scanning appointments.

What does the study involve?
Participants are randomly allocated to receive 6 weeks of either IPC or CBT. After 12 weeks their mood, well-being, relationship satisfaction and use of health care are assessed. Participants, their partners and staff providing treatments are interviewed in order to understand whether IPC is an acceptable approach and if any changes required for the future trial design.

What are the possible benefits and risks of participating?
Pregnant women with antenatal depression will be offered talking therapy and the study will help to decide which treatment is best for women with low mood in pregnancy. Those with more severe depression will be referred for more intensive treatment and anyone who finds taking part upsetting can be referred to their midwife or GP for further help.

Where is the study run from?
The study is run from the University of Bristol and patients will be recruited in Bristol and Exeter (UK)

When is the study starting and how long is it expected to run for?
September 2018 to May 2020

Who is funding the study?

Study acronymADAGIO
Study hypothesisA trial to examine the feasibility and acceptability of conducting a full-scale RCT to compare the effectiveness of IPC compared to low-intensity CBT for mild to moderate depression during pregnancy.

ConditionAntenatal depression
Intervention12 low-intensity practitioners working in NHS psychological treatment services will be randomised to receive training in IPC or booster training in CBT. This will be evenly split across two centres, Bristol and Exeter.

60 women with mild to moderate depression (EPDS score of 10 or more and ICD 10 criteria according to the revised Clinical Interview Schedule) will be recruited (30 at each site) at midwife clinic appointments and ultrasound scanning appointments. Women between 10 and 20 weeks of pregnancy and meeting criteria for mild to moderate depression will be randomised to receive six sessions of IPC or CBT from the trained practitioners.

Outcomes will be collected online or by telephone 12 weeks following randomisation. These will include: the Edinburgh Depression Scale (questionnaire), relationship measures (Revised Dyadic Adjustment Scale and Maternal Antenatal Attachment Scale questionnaires), health economic measures (EQ-5D-5L and ReQol10 questionnaires).

The number of sessions attended, number including the partner, whether step up to more intense psychological intervention is needed, use of medication, and use of secondary mental health services will also be recorded from practitioner records.
In-depth interviews will be conducted with women who have completed IPC (10-12 women) or CBT (5-6 women) and their partners focusing on the acceptability and perceived effectiveness of the talking therapy. Interviews will also be conducted with study decliners, where possible, to understand ways in which participation might be supported. Practitioners in the IPC arm, their supervisors and midwives, will be interviewed at the end of the intervention to focus on the acceptability, strengths and weaknesses of the intervention and recruitment process.
Intervention typeBehavioural
Primary outcome measure1. Recruitment rate, measured using trial documentation after 9 months of recruitment (October 2019)
2. Number of women who receive complete IPC treatment as judged by the practitioner from practitioner records at the end of the trial
3. Number of women who complete outcome data, measured 4 months after recruitment for each participant
4. Acceptability of IPC and trial design assessed using in-depth interviews at 4-6 months after recruitment
5. Supervisor’s rating of practitioner’s adherence to the IPC model at the end of the trial
Secondary outcome measuresMeasured at baseline and 12 weeks after recruitment for each participant using validated tools completed on paper or online:
1. Depression symptoms are measured using Edinburgh Depression Scale (EPDS)
2. Partner satisfaction and relationships are measured using Revised Dyadic Adjustment Scales (RDAS)
3. Maternal attachment to her unborn baby is measured using Maternal Antenatal Attachment Scale (MAAS)
4. Health-based wellbeing is measured using EQ-5D-5L
5. Wellbeing, particularly for mental health problems, is measured using ReQol-10
