Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
"ReCog" is a four-week manualised intervention based on principles of cognitive behavioural therapy and cognitive rehabilitation. It comprises 4 two-hour sessions involving education, skills training and skills practice on topics such as memory and attention, and between-session homework. The intervention is delivered in weekly group sessions of 3-10 participants with 2 facilitators. Homework takes approximately 30-60 minutes per week. Treatment adherence is monitored via session attendance and homework completion

Rehabilitation
Comparator / control treatment
1. Waitlist group. These participants are offered the intervention after all assessments are completed (4.5 months after the initial assessment). Waitlist participants are able to access standard medical and health treatments, with no specific restrictions other than not participating in the ReCog intervention until after assessments are completed. 2. Healthy volunteers with similar age and education to cancer survivors participate as a further comparison group; they participate in assessments only and do not receive any treatment or training

Efficacy
Statistical methods / analysis
A sample size of a minimum 20 participants per group was planned based on previous data showing effect sizes in the approximate range Cohen's d=0.5 to d=1.0. This would provide power of more than 80% at alpha level = .05, for detecting a Group x Time interaction. Analysis plan: Group x Time repeated measures ANOVAs.
