Digital Intervention Targeting Cancer-related Cognitive Impairments

Many cancer survivors report cognitive challenges, including problems with concentration, attention, memory, processing speed, and executive functions. These cognitive impairments can persist for years after cancer treatment and are associated with reduced functioning at home and work.

Several approaches for managing cognitive difficulties are described in the literature. One approach is drill-and-practice interventions involving repetitive cognitive training, often employing computer-based tasks that increase in difficulty. Other interventions focus on strategy-based exercises, teaching patients to apply coping strategies in everyday situations. Additionally, psychoeducation is an important component in treating cognitive impairments.

Access to interventions for cognitive impairments remains limited. This limited may be a consequence of limited healthcare professionals resources. One potential solution is to offer digital interventions. The research literature shows that digital interventions are as effective as face-to-face treatment for mental health conditions such as anxiety and depression. In a previous study, we also found that digital interventions for cognitive impairments in depression, to be feasible. Offering digital interventions for cancer-related cognitive impairments might therefore be a promising approach for addressing one of the most common late effects following cancer treatment.

This study aims to assess the preliminary effects and the feasibility of a digital intervention for cancer-related cognitive impairments. Specifically, it aims to reduce self-reported cancer-related cognitive impairments. Additionally, we will examine whether the intervention increase performance on objectively measured cognitive tests. Other outcomes are rumination, life satisfaction, fatigue, depressive symptoms, and anxiety symptoms. Qualitative feedback from participants on their experience with the intervention will be used to refine the program. We will also assess the feasibility of a recently translated questionnaire for measuring working memory in this patient group. The study will include 60 cancer survivors. Thirty of these will receive the digital intervention and 30 will receive paper and pencil crossword and sudoku tasks.

The research questions are:

1. What preliminary changes in self-reported cognitive impairments and other clinical outcomes are observed among cancer survivors after receiving the digital intervention? 2. To what extent do clinical and demographic factors influence the usage and response to a digital intervention for cognitive impairments following cancer treatment? 3. How feasible is the newly developed digital intervention for cognitive impairments? 4. How do cancer survivors experience a newly developed digital intervention for cognitive impairments? 5. How effective is the translated version of the Working Memory Assessment Questionnaire in measuring cognitive impairments among Norwegian cancer survivors?
