Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Eligible participants will receive 6 x 1.5 hr group-based Acceptance and Commitment Therapy delivered weekly by one psychologist with experience in ACT interventions, supported by a co-facilitating psychologist with experience in psycho-oncology. Group size will be at a maximum of 8 participants per group. The sessions will involve psycho-education, group discussion and group activities (e.g. mindfulness). Adherence will be through attendance logs, text message reminders that participants reply to, and observation by co-facilitators.

The intervention will be based off an ACT protocol used by Feros, Lane, Ciarrochi, and Blackledge (2013) developed by recognised trainers in ACT. This protocol contains a therapist manual and a client manual that provides structure in the form of four modules targeting ACT processes: increasing effective action orientation, mindfulness, self as context, and formal value clarification and commitment. These are divided into four modules: Module 1 – Letting go of unhelpful struggles and making room for living; Module 2 – How we get stuck in our minds and lose sight of our lives as it’s happening now; Module 3 – You are more than your pain, you are more than your suffering, you are more than your cancer; and Module 4 – Moving towards a vital, meaningful life with your pain. Each module contains activities based around metaphors and participants are encouraged to write their responses to session activities and homework readings in their workbook. As there is an emphasis on the protocol on process rather than content, each activity can be modified based on group understanding and ability in order to target the process. The manual outlines 9 x 60-minute individual sessions. In a previous unpublished pilot study, this manual was adapted for a 6-week, 90-minute group therapy format.

Efficacy
Statistical methods / analysis
The sample size was calculated based on the effect size of similar interventions and our pilot study. These studies estimate small and medium effects for the measures used. It is anticipated that analyses will consist of between-within groups ANOVAs with 4 measurement points. In order to have a power of .80 to detect a medium effect, it is estimated that a minimum sample of 24 will be required.

Summary
Brief summary
The purpose of this study is to test the effect of Acceptance and Commitment Therapy on wellbeing.

Who is it for?
You may be eligible for this study if you are aged 18 or over, and have had treatment for breast cancer within the last 2 years.

Study details
Participants in this study will be randomised by chance (like flipping a coin) into two groups. One group (comparator) will continue treatment as usual, and will be able to access the intervention after a 3 month wait. The other group will immediately commence the intervention. The intervention, called Acceptance and Commitment Therapy involves six 90min group sessions, one session per week, with a psychologist. The intervention also involves some homework tasks between sessions. As part of the study, all participants will complete questionnaires.

It is hoped that this study will contributed to improved quality of life in breast cancer survivors.
