Cognitive deficits are frequently reported following cancer treatment and can significantly impact daily functioning. These cognitive impairments often persist for years after cancer treatment. This study aimed to examine several aspects of a newly developed digital intervention designed to address cognitive impairments. Specifically, it focused on: (1) evaluating the preliminary effects of the intervention, (2) identifying predictors of treatment response, (3) assessing the feasibility of both the intervention and the study design, (4) gathering participant feedback on the intervention, and (5) testing the applicability of the Norwegian version of the Working Memory Questionnaire within this patient group.
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.

| Digital intervention targeting cancer related cognitive imapriments. | Experimental | Participants will undergo a digital intervention designed to address cognitive impairments. The program includes psychoeducation, cognitive training exercises, compensatory strategies, and cognitive restructuring. Weekly therapist support will be available via a chat function to provide guidance and feedback. Participants are encouraged to complete the intervention within a six-week timeframe. |
|
| Crossword and sudoku tasks | Active Comparator | Participants will engage in crossword and Sudoku tasks, with a minimum recommended practice of 15 minutes per day over a six-week period. |

| Digital intervention targeting cancer-related cognitive impairments | Behavioral | The intervention is developed using a person-centered approach and includes key components such as psychoeducation, cognitive training, compensatory strategy training, and cognitive restructuring exercises. Participants receive weekly remote support from a therapist and are encouraged to complete the program within a six-week period. |

| The Functional Assessment of Cancer Therapy- Cognitive Function | The Functional Assessment of Cancer Therapy- Cognitive Function (FACT-Cog) is a validated questionnaire consisting of 37 items designed to assess cognitive difficulties in cancer survivors. It includes four subscales: perceived cognitive impairment, cognitive abilities, feedback from others, and the impact of cognitive decline on quality of life. Total scores ranges from 0-148. Higher scores indicate better cognitive function. | pre-assessment to two-year follow-up |
| Measure | Description | Time Frame |
|---|---|---|
| Digit Span Wechsler Adult Intelligence Scale-IV | Digit Span Wechsler Adult Intelligence Scale-IV measures auditory attention span and working memory. Numbers are read aloud to participants, who repeat the sequence. The sequence length increases, and participants also repeat sequences backward. This test | Pre- to six-month follow-up assessments |
| Measure | Description | Time Frame |
|---|---|---|
| Rumination response scale | Rumination response scale (RRS) consists of 22 items measuring aspects of rumination. Total scores ranges from 22-88. Higher scores indicate greater levels of rumination. The RRS can be divided into three subscales: depression-related thoughts, brooding, and reflection. | pre- to two year follow-up assessment |
The target group consists of individuals who have previously undergone cancer treatment (N=60).

| Crossword and sudoku taks | Behavioral | Participants receive crossword and sudoku tasks. They are encourraged to solve such tasks for a minimum of 15 minutes daily for six weeks. |

| Patient Health Questionnaire-9 |
Patient Health Questionnaire-9 (PHQ-9) onsists of nine items that assess depressive symptoms. Scores ranges from 0-27. Higher scores indicate more symptoms. . |
| Pre- to two-year follow-up assessment |
| The Functional Assessment of Chronic Illness Therapy-Fatigue | The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT) is a 13-item questionnaire that assesses fatigue and its implications for daily functioning. Total scores ranges from 0 to 52. Higher scores represents less fatigue. | Pre- to two years follow-up assessments |
| The Satisfaction with Life Scale | The The Satisfaction with Life Scale (SWLS) measure life satisfaction. Total scores ranges from 5-35. Higher scores indicate greater level of life satisfaction. This questionnaire consists of five items. | Pre-assessment to two-year follow-up |
