The interventions The experimental intervention (GWDP) consists of three 20-minutes writing sessions in which instructions are provided to patients that have experienced the traumatic event of cancer diagnosis and therapies. Initially, participants are invited to recall chronologically the facts concerning the traumatic event, and then to label the emotions related to those facts, appraise immediate changes in priorities, reflect on their current feelings, and on coping mechanisms they have learned. Moreover, they are asked to reflect on how the experience of cancer has changed their view about life and themselves, teaching them to cope with other difficulties that may arise in the future.
