Brief Summary

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 randomized factorial trial at Karolinska Institutet, Stockholm, Sweden, 400 cancer survivors with psychiatric symptoms are enrolled in variations on a 10-week therapist-guided online psychological treatment intended to address the negative psychological long-term effects of cancer. The aim is to determine the contribution of treatment components to the overall effect.

Outcome Measures

Primary Outcomes (3)

  • General anxiety

    General Anxiety Disorder 7 (GAD-7, theoretical range: 0-21, where a higher score indicates more general anxiety). The phrasing is revised to concern the past week. The conventional version is also administered at screening (within 6 months before treatment), used to inform the eligibility assessment and to describe the sample.

    Pre-treatment (within 2 weeks before treatment), via weekly assessments, to post-treatment (after treatment, completed within 90 days). Secondary analysis: from pre-treatment up to follow-up 12-months after treatment (completed within 90 days).

  • Depressive symptoms

    Patient Health Questionnaire 9 (PHQ-9, theoretical range: 0-27, where a higher score indicates more symptoms of depression). The phrasing is revised to concern the past week. The conventional version is also administered at screening (within 6 months before treatment), used to inform the eligibility assessment and to describe the sample.

    Pre-treatment (within 2 weeks before treatment), via weekly assessments, to post-treatment (after treatment, completed within 90 days). Secondary analysis: from pre-treatment up to follow-up 12-months after treatment (completed within 90 days).

  • Fear of cancer recurrence

    9-item Fear of Cancer Recurrence Inventory (FCRI-9, theoretical range: 0-36, where a higher score indicates a more pronounced fear of cancer recurrence). This scale is also administered at screening (within 6 months before treatment), used to inform the eligibility assessment and to describe the sample.

    Pre-treatment (within 2 weeks before treatment), via weekly assessments, to post-treatment (after treatment, completed within 90 days). Secondary analysis: from pre-treatment up to follow-up 12-months after treatment (completed within 90 days).

Secondary Outcomes (10)

  • Health anxiety

    Pre-treatment assessment (within 2 weeks before treatment) to post-treatment assessment (immediately after treatment, completed within 90 days). Secondary analysis: from pre-treatment up to follow-up 12-months after treatment (completed within 90 days).

  • Somatic symptom burden

    Pre-treatment assessment (within 2 weeks before treatment) to post-treatment assessment (immediately after treatment, completed within 90 days). Secondary analysis: from pre-treatment up to follow-up 12-months after treatment (completed within 90 days).

  • Body image distress

    Screening (within 6 months before treatment) to post-treatment assessment (immediately after treatment, completed within 90 days)

  • Disability

    Pre-treatment assessment (within 2 weeks before treatment) to post-treatment assessment (immediately after treatment, completed within 90 days). Secondary analysis: from pre-treatment up to follow-up 12-months after treatment (completed within 90 days).

  • Treatment credibility and patient expectancy of improvement

    Week 2 of treatment

  • +5 more secondary outcomes

Other Outcomes (9)

  • Process and target variables: Behavioral activation

    Pre-treatment (within 2 weeks before treatment), once each week during treatment (9 assessments in total), post-treatment (after treatment, completed within 90 days), and at follow-up 6 and 12 months after treatment (each completed within 90 days).

  • Process and target variables: Symptom preoccupation

    Pre-treatment (within 2 weeks before treatment), once each week during treatment (9 assessments in total), post-treatment (after treatment, completed within 90 days), and at follow-up 6 and 12 months after treatment (each completed within 90 days).

  • Process and target variables: Physical activity

    Pre-treatment (within 2 weeks before treatment), once each week during treatment (9 assessments in total), post-treatment (after treatment, completed within 90 days), and at follow-up 6 and 12 months after treatment (each completed within 90 days).
