Coping After Breast Cancer - a Randomized Clinical Trial With Two Digital Interventions

Coping After Breast Cancer - CABC - Stressmestring Etter Brystkreft - SEB

1. Breast cancer patients and age-matched controls are first invited to answer questions on HRQoL.
2. Among responding breast cancer patients, a subset are invited in a randomized clinical trial with two digital interventions for cancer stress management, cognitive based stress management (CBSM) and mindfulness based intervention (MBI), as well as a control group.
3. The goal is to determine whether digital CBSM or MBI can effectively reduce stress levels as compared to a control group. Second, whether these interventions can improve HRQoL (or avoid onset of HRQoL problems) for patients with breast cancer, compared to a control group.

After completing the baseline HRQoL assessment, eligible breast cancer patients will be invited to participate in a randomized clinical trial.

Those who are willing will be randomly allocated to one of the following arms: a) Digital cognitive based stress management, b) Digital mindfulness based intervention or c) Control group.

The intervention is based on a revised version of the Stressproffen app, which was developed by the Oslo University Hospital (Lise Solberg Nes, Elin Børøsund and others).

Outcome measures include measures of perceived stress and HRQoL.
