The 'Being There' manual and associated support calls used in the study linked above are being used in the current study. A number of changes have been made to the previous study design and will be tested for feasibility e.g. online recruitment expanded to carers of patients with advanced cancer (as opposed to within a palliative care unit), increased support calls and the addition of a facebook support group.

Description of intervention(s) / exposure
Participants will be recruited via online/social media advertising and within physical sites in Australia.
Participants will be provided access to an information hub, an acceptance and commitment therapy (ACT) manual and an online support group for participants facilitated by the study psychologist.
The information hub will be embedded within the study web page and will contain links to legitimate sources of written and video information that includes topics such as physical, psychological, spiritual and cultural, caring tips and information, patient and carer perspectives. The information hub will include video that outlines the resource links provided and also explains why some questions are difficult to answer and recommends carers seek support to manage distress that arises when dealing with the unknown. Participants will not be advised to spend any certain amount of time browsing these links; this will be determined by a participant's informational needs and their own preferences.
Based on ACT, the self-help manual created by Davis et al (2020) is designed to help carers cope better with their situation through psychoeducation and experiential exercises. The manual has 66 pages including 9 modules and 14 exercises (including 4 accompanying audio recordings). It will be available to participants in hard copy and as an electronic version on the study website.
A health professional (psychologist with at least introductory training in ACT) will contact participants within one week of recruitment/baseline assessment and offer up to four support check-ins (approximately 15 minutes in length via phone, video call, text or an email – depending on participant preference). The health professional and participant will establish a flexible schedule for these check-ins (over the course of one month). The purpose of the support check ins is to review participant progress and answer any questions about the information or exercises provided. The psychologist will respond with positive and encouraging feedback and offer advice and instruction.
The intervention manual is designed to be taken at the participant's own pace. Instructions provided within state "Some people may prefer to review the whole booklet in one or two sittings. If so, we strongly recommend that you return to it and review the content and exercises again at a later date. This allows you to integrate the skills over a longer period
of time. Others may choose to complete the booklet more slowly. The intervention period is considered to be 1 month (post baseline); support check-ins will be conducted within this timeframe and participants will be encouraged to complete the manual within this time frame.
Participants will be offered the opportunity to join the study’s Facebook support group page. The group will be the ‘secret’ group setting from Facebook; a secret group that involves only those an administrator allows to participate. Participants are not required to post to the Facebook group page. Upon enrollment we will advise participants that if we become concerned about any one individual's need for additional counselling we will refer him or her to appropriate services.
Approximately bi-weekly (depending on participant recruitment rate), material from the iACT manual and other relevant psychological support material (based on the observations of the discussions and clinical reasoning by the psychologist) will be posted on the group Facebook page, followed by a discussion question from the psychologist. The psychologist will review postings daily and respond when appropriate (clarifying, answering questions, offering encouragement, or asking additional facilitating questions).
As part of the feasibility data to inform a future effectiveness trial, participants will be offered the option to engage in study components via internet, phone and traditional hard copy/mail out methods. The participant follow-up survey includes questions as to which components of the intervention the participant engaged in.
Qualitative Interviews
Following completion of the intervention and follow-up survey, participants who consent to be contacted will be contacted with an invitation to participate in a qualitative interview. Individual qualitative interviews will be conducted until informational redundancy is reached. The interviews will be guided by a semi-structured interview guide and be approximately 30 minutes in length. Participants will have the option of completing the interviews via telephone or video call– depending on their preference. Interviews will be audio recorded and transcribed.

Statistical methods / analysis
The primary objective of this project is to determine the feasibility and acceptability of the proposed intervention. Formal power calculations are not typically undertaken in feasibility trials. Based on the recruitment timeline and recommendations for feasibility studies we intend to recruit 30 carers. To account for caregiver drop out of 30% as seen in similar studies, we inflate this to 50.
Descriptive statistics on the number of eligible participants, recruitment and retention rate, reasons for dropout, protocol completion, number of support check-ins and acceptability items will be provided. Descriptive analysis of baseline demographics and clinical characteristics will be presented. Paired t-tests will compare scores from baseline to 3 months for the following outcomes
• Experiential avoidance
• Anticipatory grief
• Valued-living
• Psychological well-being
• Social support
Qualitative Interviews
Interviews will continue until informational redundancy is reached (hypothesised to be approximately 10 participants) to further explore the feasibility and acceptability of the self-help intervention, and the potential barriers for carers.
Qualitative interview data will be analysed using a thematic analysis approach.

Summary
Brief summary
This study will test the feasibility and acceptability of an information and Acceptance and Commitment Therapy based (ACT) self-help intervention for people who self-identify as carers of a person diagnosed with advanced cancer. Who is it for? You may be eligible for this study if you are aged 18 or older, you self-identify as a carer of a person diagnosed with advanced cancer (defined as a diagnosis that has been described to the person as stage 4/advanced/metastatic, and is incurable or terminal) and you are living in New South Wales, Australia. People who have been diagnosed with cancer will not be eligible for this study. Study details All participants who choose to enrol in this study will be provided access to an online information hub, an an acceptance and commitment therapy (ACT) manual and an online support group for participants facilitated by the study psychologist. The information hub will be embedded within the study web page and will contain links to legitimate sources of written and video information that includes topics such as physical, psychological, spiritual and cultural, caring tips and information, patient and carer perspectives. The ACT self-help manual is designed to help carers cope better with their situation through psychoeducation and experiential exercises, including 4 accompanying audio recordings. It will be available to participants in hard copy and as an electronic version on the study website. A study psychologist will contact participants within one week of recruitment/baseline assessment and offer up to four support check-ins. Participants will be offered the opportunity to join the study’s Facebook support group page. At the conclusion of the study, participants will be asked to attend a one-on-on interview with a member of the research team to discuss their experiences during their participation in the study. It is hoped this research will demonstrate that self-help therapeutic practices for carers of people with advanced cancer are feasible to deliver remotely, and that these practices may reduce stress and improve the quality of life for these carers.
