What this trial studies

This clinical trial evaluates the effectiveness of internet-delivered Cognitive Behavioral Therapy (iCBT) in reducing symptoms of prolonged grief disorder in adults who have lost a loved one. Participants will be randomly assigned to either the iCBT group, an active control group, or a waitlist control group. The study aims to assess the short and long-term effects of iCBT on symptoms of prolonged grief, posttraumatic stress, and depression, while also exploring the mechanisms that contribute to its effectiveness. Follow-up assessments will be conducted at 6 and 12 months post-treatment to gauge the lasting impact of the intervention.

Who should consider this trial

Good fit: Ideal candidates are adults residing in Sweden who have experienced the death of a loved one at least six months prior and are suffering from prolonged grief disorder.

Not a fit: Patients with ongoing severe psychiatric issues or those requiring more urgent care may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly alleviate prolonged grief symptoms and improve mental health outcomes for affected individuals.

How similar studies have performed: Previous studies have indicated that Cognitive Behavioral Therapy can be effective for prolonged grief, but this trial aims to expand on that with a larger sample size and comprehensive follow-up assessments.
