Plain English Summary

Background and study aims
Women who have experienced domestic violence and abuse (DVA) often develop post-traumatic stress disorder (PTSD) which includes reliving the traumatic events through nightmares and disturbing memories, feeling isolated, irritated and guilty, having difficulties with concentration and functioning. Children whose mothers have PTSD are at risk of developing mental health problems. Unlike a one-off traumatic event, repeated DVA results in PTSD that is harder to treat. Standard treatment for PTSD is a past-focused talking therapy which teaches how to change negative thoughts and feelings into more positive ones through ‘reliving’ traumatic memories. Many survivors of DVA drop out of the standard treatment because they find such an approach too upsetting or do not feel better. In contrast, mindfulness is a present focused talking therapy which teaches how to respond to one-self with acceptance and self-compassion. It is known that mindfulness works well for depression. In collaboration with DVA survivors and mental health professionals, the researchers have adapted a standard mindfulness course for depression to fit the special treatment preferences and needs of DVA survivors with PTSD. Now they plan to test the adapted mindfulness course for PTSD in a small study. This will help them to design a bigger study which will answer the question about the effectiveness and value for money of the adapted mindfulness course.

Who can participate?
Women service users at collaborating DVA agency, aged 18 and over, with clinically important symptoms of PTSD

What does the study involve?
54 service users with PTSD are randomly allocated into two groups. Half of the women attend eight mindfulness group sessions, while the other half receive the standard talking therapy on the NHS. The two groups are compared with respect to mental health status of women and their children before the allocation and six months later. All patients are also interviewed about their treatment experiences.

What are the possible benefits and risks of participating?
Women will have a 75% chance of getting a new talking therapy. However, it is not yet known whether it is helpful. By taking part, women will be having a say in whether the new mindfulness course is acceptable and should be tested in a bigger study. Taking part in the study means that woman will have additional contacts with the study researcher over a period of six months. This may increase the risk of other people including perpetrator of DVA finding out about woman’s participation in the study which can potentially lead to escalation of abuse. However, the researchers will always do their best to contact participants in a safe way. For example, they will only phone the woman at a time when she tells us it is safe to do so. They will also arrange safe places to meet with or be contacted by the researcher and to store study documentation. Participant’s safety will always be their priority.

Post-traumatic stress disorder


The trialists will recruit 54 women with PTSD from DVA agency and randomly allocate them into two arms. Half of the women will attend eight mindfulness group sessions, while the other half will receive the standard past-focused talking therapy. The two groups will be compared with respect to mental health status of women before the allocation and six months later. The trialists will also interview all women about their treatment and study experiences. If they find that the mindfulness course is acceptable and that the study plan could work, they will design a full size trial and apply for funding.

Primary outcome measure

Primary feasibility outcomes:
Recruitment/randomisation rate is measured as a proportion of participants recruited/randomised into two arms; the denominator will be the number of participants eligible for recruitment/randomisation by the end of the randomisation period.

Secondary outcome measures

Secondary feasibility outcomes:
1. Intervention uptake is measured as a proportion of participants who took up the intervention and usual care; the denominator will be the number of participants randomised in the arm, respectively, at 6 month post-randomisation
2. Intervention retention is measured as a proportion of participants in the intervention arm who received the “minimum dose” of the intervention, four sessions of mindfulness intervention, at 6 months post-randomisation
3. Follow-up rate is measured as a proportion of participants followed up at six months post-randomisation out of those enrolled in the trial. The proportion who have been lost to follow-up will also be calculated by the trial arms, at 6 months post-randomisation
4. Participant experience is evaluated through qualitative interviews at 6 months post-randomisation

Participant inclusion criteria

Target population: service users from third sector DVA agency:
1. Female
2. Referred or self-referred to collaborating third sector organisation for DVA advocacy
3. No physical or sexual victimization in the prior two months

IPD sharing statement
The datasets generated during and/or analysed during the current study will be stored in a non-publically available repository. After study has concluded, the trialists will deposit the anonymised data in the University of Bristol Data Repository where it will be made available to other health care researchers.
