Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
For phase 1: A focus group to obtain feedback on the content and delivery of the intervention.
- Participants will be provided with an adapted version of a cognitive rehabilitation intervention (i.e., Responding to Cognitive Concerns [ReCog]) manual that was designed specifically for adult cancer survivors who have completed primary treatment (this is not a readily available resource). The program incorporates principles of cognitive behavioural therapy (CBT) and cognitive rehabilitation to address typical difficulties reported by cancer patients related to their cognition, such as difficulties with memory, attention, executive functioning and fatigue. The program entails psychoeducation, discussions and interactive activities.
- Participants are expected to spend no more than 1 hour familiarising themselves with the intervention content in their own time and share their feedback in a 2-hour online focus group facilitated by members of the research team.
- The focus group will consist of 6 participants and 2 research team members.
- More information can be found using this link: https://redcap.link/FocusGroupPROCOG
- Phase one will occur a few months prior to phase 2 to ensure there is adequate time for any changes to the manual to be reviewed by Human Research Ethics team at Macquarie University.

For phase 2: A 4-week online group cognitive rehabilitation program.
- Eligible participants will be provided with a participants handbook for a cognitive rehabilitation intervention, codesigned with prostate cancer patients (i.e., an adapted version of the Responding to Cognitive Concerns [ReCog] manual).
- Participation involved attending weekly 2-hour sessions (with a ~15 min break in-between) via telehealth over 4 weeks as well as completing 4 assessments (less than 1 hour long each): 3 to 5 weeks before the program starts, within 1 week of the program starting, within 1 week of the program ending and 3 weeks after the program ends. They will also be required to complete a 2-minute survey weekly for 10-12 weeks.
- There will be a maximum of 6 participants in the group.
- The intervention will be delivered by a registered psychologist undergoing a neuropsychology registrar program.
- A fidelity checklist will used to monitor adherence to the intervention
- More information can be found using this link: https://redcap.link/GroupPROCOG

Seperate cohorts are required for phase 1 and phase 2.


Single-case experimental designs (SCED) refer to experimental methodologies designed to assess the impact of an intervention on a limited number of participants. These designs involve repeated measurements, the sequential introduction of an intervention and specialized data analysis techniques such as visual analysis and specific statistical methods. We will be using the multiple-baseline design whereby participants will be randomised to a baseline period between 3 to 5 weeks.

Outcomes
Primary outcome [1] 335686 0
Phase 1: focus group
- qualitative feedback on the content and delivery of the intervention
Timepoint [1] 335686 0
One online 2-hour focus group session that will be recorded and transcribed.
Primary outcome [2] 335795 0
Phase 2: Series of SCED
- Acceptability of the group intervention through a semi-structured interview.
Questions for the semi-structured interview were informed by Sekhon et al.’s (2017) theoretical framework of acceptability, comprising of seven constructs: affective attitude, burden, ethicality, intervention coherence, opportunity costs, perceived effectiveness, and self-efficacy. Each participant will be interview individually.
Timepoint [2] 335795 0
The acceptability of intervention activities will be assessed by an exit feedback interview following the end of the intervention program (i.e., a week or two following the 4-week program).
Primary outcome [3] 335796 0
Phase 2: Series of SCED
The feasibility of the intervention will be measured by participant attendance to session (i.e., attendance rates of 70%), using a log of attendence.
Timepoint [3] 335796 0
Weekly record kept by the facilitator over the 4-week intervention period.
Secondary outcome [1] 425183 0
Changes to perceived cognitive functioning will be measured using the 18-item Perceived Cognitive Impairment (PCI18) scale from the Functional Assessment of Cancer Therapy-Cognitive Subscale (FACT-cog, version 3; Wagner et al., 2009) and the PROMIS 8-item Cognitive Functioning Scale (PROMIS CF-SF-8a; Lai et al., 2014).
Timepoint [1] 425183 0
Weekly for 10-12 weeks from baseline, throughout the intervention and post-intervention.
Secondary outcome [2] 425188 0
Brief cognitive testing over videoconferencing.

Following International Cancer and Cognition Task Force (ICCTF) guidelines the following tests will be used:
- Hopkins Verbal Learning Test-Revised (HVLT-R; Benedict, 1998)
- Controlled Oral Word Association (COWA) of the Multilingual Aphasia Examination (Benton et al., 1989)
- Oral version of the Symbol Digit Modalities Test (SDMT; Smith, 1982) to measure speed of information processing.
