Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Materials: Online therapeutic iCBT intervention (CarersCanADAPT) will be delivered via a secure web based program to study participants over a 6 week period. Each section will take 1-2 hours to complete. The lesson topics are:
Lesson 1: Learning about depression and anxiety
Lesson 2: Identifying and tackling thoughts
Lesson 3: Tackling unhelpful behaviours
Lesson 4: Helpful coping
Lesson 5: Adjusting to change, communication, and support
Lesson 6: Staying well in the long term and getting even better
Website back-end analytics will be used to monitor adherence to the intervention - data will be captured on number of log-ins, date of log-ins, time spent on each section, and interaction with activities, e.g. downloading worksheets and summaries.

Procedures: Participants in the RCT will be randomly assigned to the intervention or wait list control condition, 1:1 allocation ratio.
The randomisation will be electronically generated using an access database.
Participants in the intervention (iCBT) condition will receive immediate access to CarersCanADAPT iCBT via the secure CarersCanADAPT Portal and will complete 1 lesson per week over 6 weeks, and then complete follow-up measures immediately post intervention and 8 weeks later (i.e. 14 weeks).
Participants in the wait list control condition will not be provided with the CarersCanADAPT iCBT and will complete measures only. After the wait list control group has completed 14 weeks on the wait list, they will receive access to the CarersCanDAPT iCBT and will continue to complete measures for the duration of the intervention and follow-up period.
Additionally, Participants will complete the PHQ-9 and GAD-7 as part of the pre-lesson screening/monitoring measure every 2 weeks during the intervention phase

Delivery: The intervention will be delivered by the research team, who will send participants a link to access the web-platform which contains structured lessons and activities, supported by multimedia storylines. The intervention will be delivered online. Participants may complete the intervention anywhere they chose where they have access to a device which connects to the internet. There will be six lessons for individuals to work through at their own pace. One lesson will be made available weekly to participants, who will be sent an email reminder when a new lesson becomes available.
Participants who have not completed the training will be sent up to 3 reminder emails from the research team to encourage completion.

Behaviour
Comparator / control treatment
There will be one waitlist control group in the trial that will receive routine care, while they wait 14 weeks to access the intervention. After 14 weeks the control group will complete the intervention.

Carers in the waitlist control condition who receive routine care will be provided with general information and support via referral to the “Caring for Someone with Cancer” resources provided by the Cancer Council NSW. In addition, carers will be provided with referral to the Australian Government Carers Gateway website and will receive a brief factsheet on the services that Carers Gateway provides.

Acceptability of iCBT module assessed with optional post-intervention qualitative interview. Interviews are expected to last approximately 30 minutes and will be conducted one-on-one over the phone, zoom or in person. Interviews will be guided by an interview schedule of open-ended questions about participant's experiences using the module and their feedback on the module content. All interviews will be audio recorded and transcribed verbatim.

Quantitative Data

To address the aims of this trial, linear mixed effects models will be conducted to examine the differences in anxiety, depression, and stress between intervention and waitlist control groups over each follow-up. The model will be designed with fixed effects (intervention/waitlist control groups) and random effects (individual participants).

Qualitative Data
All participant interviews will be audio recorded and then transcribed verbatim. The researchers will thematically analyse the data using the Framework Methods approach.
