A Swedish Internet CBT for Prolonged Grief Disorder: a Three-armed RCT

Condition(s) studied

Investigational drug(s) / intervention(s)

iCBT for prolonged grief: Participants will undergo a 10-week internet-delivered, therapist-led cognitive behavioral therapy treatment (iCBT) for prolonged grief, which includes psychoeducation about grief and common grief reactions, exposure, cognitive restructuring and behavioral activation.

Active control: Participants will undergo a 10-week internet-delivered, therapist-led treatment, which includes psychoeducation about grief and common grief reactions.

Study summary

The goal of this clinical trial is to evaluate the effectiveness of internet-delivered Cognitive Behavioral Therapy (iCBT) in reducing symptoms of prolonged grief in adults diagnosed with prolonged grief disorder.

The main questions the study aims to answer are:

* Does iCBT reduce symptoms of prolonged grief disorder, posttraumatic stress, and depression following the death of a loved one in the short and long term?
* What mechanisms contribute to the effectiveness of iCBT in treating prolonged grief disorder?

The iCBT intervention will be compared to a waitlist control group and an active control group to see if iCBT reduces symptoms of prolonged grief disorder more effectively than no treatment or a placebo treatment.

Participants will:

* Be randomly assigned to either the iCBT group, an active control group or a waitlist control group
* Complete online assessments of symptom severity, grief cognitions, and level of avoidance before, during and after intervention
* Engage in 10 weeks of a therapist-guided online treatment
