Description of intervention(s) / exposure
The manualised Making the Most of your Memory: An everyday Memory Skills Program (Radford, et al., 2012) adapted for Telehealth delivery (Lawson, et al., 2020), will be modified to include psychological intervention for managing distress, mood and anxiety commonly exacerbated following stroke. Weekly sessions will be 2.5 hours for 6 weeks in length and follow a consistent structure each week: (i) Psychoeducation on cognitive functioning, (ii) Introduction and practice of internal and external cognitive compensatory strategies, (iii) Education on Lifestyle factors (diet, sleep and exercise on cognitive function and wellbeing), and (iv) Psychoeducation and Practice of Psychological Strategies for mood and anxiety (eg. psychoeducation on emotional changes following stroke, including stress, depression and anxiety, cognitive and behavioural interventions including cognitive challenging of unhelpful thinking, behavioural interventions for low mood, stress management strategies including relaxation and mindfulness, and Value-based action). The mode of delivery will be telehealth sessions of 8 participants. They will be conducted by Clinical Psychologists and/or Clinical Neuropsychologists via PEXIP, a NSW Health approved platform with the capability to provide secure group-based intervention with presentation capabilities to display content and for interactive participant engagement. We will monitor attendance, engagement in skills practice during Group, and completion of homework tasks.

Comparator / control treatment
Waitlist control.
Participants who are randomly selected to be part of the waitlist control group will still complete the same assessments of mood and cognition, (Initial, 7-8 weeks, and Further 3 month’s follow-up) as those participants who complete the Telehealth Group. After completion of the waitlist period (which is after the further 3 month follow-up testing session), waitlist participants will then be invited to complete the Telehealth Group. The purpose of the waitlist control group is to allow an accurate evaluation of whether the Telehealth Group is of benefit, over and above the improvements people may notice with time since their stroke. After completion of the waitlist period, waitlist participants will then be invited to complete the Telehealth Group.

Statistical methods / analysis
GPower was used to calculate power for the Intervention Group x Time on our primary outcome measure, Rey Auditory Verbal Learning Test (RAVLT), as previous research indicates medium effect sizes of cognitive rehabilitation in this patient group (Miller & Radfor, 2014). With 0.8 power, to detect a conservative small to medium effect (f=.15) on this measure, a total of 74 participants is required (n=37 in each experimental Group). To account for potential dropout, an additional 6 participants will be recruited (3 in each group) giving a total of 80 participants.

Summary
Brief summary
This study aims to evaluate the effectiveness of a combined 6 week Cognitive Rehabilitation and Psychological intervention delivered via Telehealth in improving patient outcomes post-stroke in a pragmatic randomised wait-list controlled trial. It is expected that the proposed intervention will improve patients’ cognition, psychological wellbeing, functional abilities and QoL. Eighty participants with a diagnosis of stroke within the previous 6-months and self-reported cognitive or psychological difficulties referred to the ISLHD Rehabilitation and Medical Psychology Department by multidisciplinary teams on Rehabilitation and Neurology wards within ISLHD, will be randomised to a 6-week combined Cognitive Rehabilitation and Psychological Telehealth Intervention or Waitlist Control Group. Participants will attend an assessment session prior to the Group, immediately following the Group, and at 3 months follow up after completing group, and will be assessed with a varied of neuropsychological tests (primary outcome measure being RAVLT) and psychological wellbeing measures (DASS-21) and quality of life(SF-36) .
