Negative psychological effects of cancer are common, but cancer survivors are rarely offered structured psychological treatment. Internet-delivered treatments have shown some promise, but specific treatment components have not been empirically evaluated which means that it is not clear which therapies that should be prioritized. In this factorial pilot study, 48 cancer survivors with psychiatric symptoms are enrolled in variations on a 10-week therapist-guided online psychological treatment intended to address common negative psychological long-term effects of cancer. The aim of this study is to assess the feasibility of the study design and online treatment format. Key feasibility outcomes include interest in the study, patient-reported credibility of the intervention, adherence to the treatment protocol, satisfaction with the treatment, acceptability of the measurement strategy, missing data rates, adverse events, and preliminary efficacy on anxiety, depression, the fear of recurrence, and health-related quality of life.

Feasibility 1: Feasibility of the randomized factorial design
A key feasibility outcome of this pilot study is the overall experience of study administrators and therapists tasked with the assignment and delivery of treatment variants in accordance with the randomized factorial design. After the main phase, all study administrators and therapists will be asked to rate the feasibility of the planned study design from 0 ("not feasible at all") to 10 ("fully feasible"), which will reported as a mean (SD) and median.
