Is this trial a fit for you?

Likely a good fit

Adult cancer survivors (≥18 years), at least 6 months after primary therapy, living in Region Stockholm, Västra Götaland, or Region Skåne, who have clinically significant anxiety, depression, or fear of recurrence and can read Swedish and use an internet device are ideal candidates.

Probably not a fit

Patients with severe psychiatric disorders (e.g., psychosis or bipolar disorder), high suicide risk, very poor prognosis or advanced (stage IV) cancer, those who cannot use Swedish or lack reliable internet access are unlikely to benefit or be eligible.

What this trial studies

In this randomized factorial trial at Karolinska Institutet, 400 cancer survivors with clinically significant anxiety, depression, or fear of recurrence are randomized to receive variations of a 10-week therapist-guided online psychological program. The intervention manipulates four components—support and information, behavioral activation, systematic exposure with mindfulness training, and promotion of health behaviors—to determine which elements contribute most to improvement. The factorial design permits estimation of each component’s independent and combined effects on symptom change using standardized self-report scales and structured interviews over the treatment and follow-up periods. Eligible participants are adults at least six months after primary cancer therapy, fluent in Swedish, residents of specified Swedish regions, and able to access the web platform via a personal electronic device.

Why it matters

Potential benefit: If successful, the trial could identify the most effective parts of online therapy so survivors can receive shorter, more focused, and more widely accessible psychological care.

How similar studies have gone: Previous internet-delivered cognitive behavioral therapy programs have shown promise in cancer survivors, but the component-level effects targeted by this factorial design are relatively untested.
