Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants randomly assigned in the Acceptance and Commitment Therapy (ACT) intervention condition will receive a 6-week, 90 minute, weekly group-based face to face program delivered by two psychologists trained in ACT and using the same guidelines detailing the administration of ACT in individual interventions and adaptation of ACT for group interventions. For this study, both psychologists will use the same set of guidelines detailing adaption of ACT activities and schedule for a group-based ACT intervention. The ACT intervention program focuses on providing participants with strategies based on the six core processes of ACT(Acceptance, Defusion, Self as Context, Values, Contact with the Present Moment, and Committed Action) aimed at enhancing their psychological flexibility and wellbeing through improving management of distress, mood and quality of life.

Participation will also involve completing an ACT workbook and practicing ACT outside group sessions. Each participant will be provided with a printed ACT workbook. During each sessions they will be invited to complete relevant session items in their workbooks. At the end of each session, they will be encouraged to complete home-based activities and practice ACT individually before the next session. After 6 weeks in the ACT intervention program, participants will cross-over to a ‘usual care’ control program.

Intervention adherence will be assessed, at the end of the study, by examining participant engagement with the ACT program as measured through auditing ACT workbooks and a thematic analysis of journal entries.

The study will take place at St Andrew’s Hospital (Toowoomba, Queensland), where both intervention and control programs will be delivered in separate identical non-adjoining meeting rooms.

Behaviour
Comparator / control treatment
There will be two control groups. Participants randomly assigned in the control groups will either: (a) first receive standard care which includes a 6-week 60 minute, weekly group-based face to face breast cancer education (BCE) control program facilitated by a trained breast care nurse and delivered by experts who will provide education presentations and accompanying slides, relating to the following 6 topics: diet, physical activity, sexuality concerns, cancer biology, relaxation techniques and sleep hygiene; or (b) first be in a wait-listed group receiving no BCE or ACT program for 6 weeks.

After 6 weeks, participants in each control group will cross-over to receive the ACT intervention program. Therefore, the three study conditions are:
- Group A: Receiving the ACT intervention program, then crossing over to the BCE control program;
- Group B: Receiving the BCE control program, then crossing over to ACT;
- Group W: Wait-listed, then crossing over to ACT

Given that educational and behavioural interventions are expected to produce effects that last beyond the administration of the intervention, a wash-out period does not apply as participants will be unable to unlearn the strategies presented during the therapy.

Outcomes
Primary outcome [1] 303315 0
Psychological flexibility will be assessed using the validated Acceptance and Action Questionnaire 2 (AAQ-2).
Timepoint [1] 303315 0
Pre-intervention (at baseline): Week1, immediately before start of each study condition (i.e., for Group A, Group B, Group W).
Post-intervention: Upon completion of each study condition, before cross-over.
Follow-up: 6 months and 12 months after the final study session.
Primary outcome [2] 303316 0
Physiological stress will be assessed by: (1) changes to measures of blood pressure and resting heart rate (blood pressure will be measured using a stethoscope, blood pressure cuff and aneloid sphygmomanometer and heart rate will be measured using a digital pulse oximeter); and (2) changes in biomarkers collected from blood and saliva samples assayed to determine the impact of self-reported wellbeing on molecular biomarkers such as stress and inflammatory biomarkers and chromosome stability (measured as relative telomere length in buccal cells and leukocytes, plasma tumour necrosis factor, interleukins and c-reactive protein, salivary amylase and cortisol (plasma and salivary)).
Timepoint [2] 303316 0
Pre-intervention (at baseline): Week1, immediately before start of each study condition (i.e., for Group A, Group B, Group W).
Post-intervention: Upon completion of each study condition, before cross-over.
Follow-up: 6 months and 12 months after the final study session.
Secondary outcome [1] 338614 0

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Random allocation will be concealed to project team members who will determine whether a participant is eligible for inclusion in the trial. Randomisation will be performed by a project team member not involved in eligibility screening and blinded to the identity of eligible participants,
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
