Interventional
Description of intervention(s) / exposure
Participants in the 'BeCALM intervention' group will receive treatment as usual, as well as the intervention.

Radiotherapy (RT) treatment session 1 - Each participant will receive pre-treatment education with a radiation therapist to discuss what to expect during treatment. During the pre-treatment education, the radiation therapist will provide a brief explanation of the biofeedback device (pulse oximeter) and how to use it. The radiation therapist will allow the participant to test the device and will briefly coach the participant on biofeedback techniques. The participant will be taken to the treatment bunker to commence RT. The participant will be provided with the pulse oximeter in the treatment bunker which they will wear for the duration of the treatment session. Sound will be enabled on the device (beep sound reflecting pulse rate), and it will be adjusted to a volume that is comfortable for the participant. Radiation therapists will provide breathing prompts during the treatment session at their discretion (via the speaker). The breathing prompts were designed, based on mindfulness exercises described in Khazan (2019) Biofeedback and Mindfulness in Everyday Life: Practical Solutions for Improving Your Health and Performance

RT treatment session 2 – Each participant will be taken straight from waiting room to the treatment bunker to commence RT. The participant will be provided the pulse oximeter in the treatment bunker which they will wear for the duration of the treatment session. Sound will be enabled on the device (beep sound reflecting pulse rate), and it will be adjusted to a volume that is comfortable for the participant. Radiation therapists will provide breathing prompts during the treatment session at their discretion (via the speaker).

RT treatment sessions generally occur five days a week (week days) for a number of weeks. Therefore, it is likely the first two sessions will occur on consecutive days.
The duration of each session is varied dependent on the type and location of the cancer.

Adherence: Radiation therapists will be required to complete a 'Treatment Observations' form at the end of each participant treatment session to record adherence to the intervention, including: whether the pulse oximeter was worn; whether the sound was on or off; if not, why?; whether breathing prompts were delivered and; if not, why?

Comparator / control treatment
Participants in the 'treatment as usual' group will receive usual care.

Treatment as usual will include:

RT treatment session 1 – Each participant will receive pre-treatment education with a radiation therapist to discuss what to expect during RT. Immediately following education, the participant will be taken to the treatment bunker to commence RT. The participant will be asked to wear the pulse oximeter (for data collection purposes only), with the sound disabled on the device.
RT treatment session 2 – The participant will be taken straight from waiting room to the treatment bunker to commence RT. Participants will be asked to wear the pulse oximeter (for data collection purposes only), with the sound will be disabled on the device.

RT treatment sessions generally occur five days a week (week days) for a number of weeks. Therefore, it is likely the first two sessions will occur on consecutive days.
The duration of each session is varied dependent on the type and location of the cancer.

Outcomes
Primary outcome [1] 329500 0
Feasibility of the intervention as measured by:

• Percentage of treatment sessions in which the intervention (pulse oximeter and breathing techniques) was successfully delivered (and reasons why not successfully delivered). Radiation therapists will be required to complete a 'Treatment Observations' form at the end of each participant treatment session to record adherence to the intervention, including: whether the pulse oximeter was worn; whether the sound was on or off; if not, why?; whether breathing prompts were delivered and; if not, why?
• Author created feasibility items included in the radiation therapist feasibility and acceptability survey
• Recruitment and retention rates (project records)
Timepoint [1] 329500 0
Treatment 2 Post RT Assessment (immediately post radiotherapy treatment 2)
Primary outcome [2] 329501 0
Acceptability of the intervention (to patients) as measured by:
• Author created acceptability items included in the Post RT participant assessments
Timepoint [2] 329501 0

Radiation therapist feasibility and acceptability survey (which will be completed following the completion of recruitment and participant data collection)
Secondary outcome [1] 402790 0
Potential Effectiveness of the intervention in reducing procedural anxiety during RT:

• Procedural anxiety will be measured using the State subscale of the State-Trait Anxiety Inventory STAI-S, in the waiting room post-treatment, at RT sessions 1 and 2.

Timepoint [1] 402790 0
Treatments 1 and 2 Post RT Assessments (immediately post radiotherapy treatment sessions)
Secondary outcome [2] 403956 0

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Individual randomisation will be via block randomisation (computer generated) to Treatment As Usual (TAU) or BeCALM. The student researcher/research assistants who will complete the randomisation are also responsible for eligibility screening, and will therefore be kept blinded to the block size to ensure that allocation can not be predicted.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be managed in REDCap. Participants will be allocated a unique computer-generated study number. Individual randomisation will be via block randomisation to Treatment As Usual (TAU) or BeCALM. The student researcher/research assistants will be kept blinded to the block size.
Masking / blinding

Efficacy
Statistical methods / analysis
A time convenience sample of adult patients with cancer scheduled to undergo RT will be recruited from the department of RT at the Calvary Mater Hospital. Recruitment will continue for a period of approximately three months, depending on recruitment rate. We anticipate recruitment of approximately 57 participants, based on: 10 patients undergoing SIM per day, a minimum of 3 days of recruitment per week, 20% meeting eligibility criteria with an 80% consent rate.

Descriptive statistics on the number of eligible participants, recruitment and retention rate and reasons for dropout will be provided. Descriptive statistics will also be provided on the sociodemographic and health characteristics of participants.

Primary outcomes
Descriptive statistics will be provided on the feasibility and acceptability assessment items.

Secondary outcomes
Differences in the mean STAI-S score from baseline to Post T2 will be analysed using a linear regression. The outcome in the model will be the individuals STAI-S score at T2 using their baseline STAI score as a covariate.

Similarly, differences in the mean DT score from baseline to Post T2 will be analysed using a linear regression. The outcome in the model will be the individuals DT score at T2 using their baseline DT score as a covariate.

Independent samples t-tests will be conducted to compare the difference in the mean treatment time between intervention and control participants at both treatment 1 and treatment 2.
