Summary
Brief summary
The rationale of the study is to evaluate the relative efficacies of Cognitive Behaviour Therapy and Mindfulness in reducing the symptoms of prolonged grief. This study compares the relative effectiveness of (a) Cognitive Behaviour Therapy, and (b) Mindfulness. It is hypothesised that both arms training will lead to grief symptom reduction but that Cognitive Behaviour Therapy will lead to greater symptom reduction at follow-up.
