Writing Technique Across Psychotherapies-From Traditional Expressive Writing to New Positive Psychology Interventions: A Narrative Review

Writing Therapy (WT) is defined as a process of investigation about personal thoughts and feelings using the act of writing as an instrument, with the aim of promoting self-healing and personal growth. WT has been integrated in specific psychotherapies with the aim of treating specific mental disorders (PTSD, depression, etc.). More recently, WT has been included in several Positive Interventions (PI) as a useful tool to promote psychological well-being. This narrative review was conducted by searching on scientific databases and analyzing essential studies, academic books and journal articles where writing therapy was applied. The aim of this review is to describe and summarize the use of WT across various psychotherapies, from the traditional applications as expressive writing, or guided autobiography, to the phenomenological-existential approach (Logotherapy) and, more recently, to the use of WT within Acceptance and Commitment Therapy (ACT). Finally, the novel applications of writing techniques from a positive psychology perspective will be analyzed. Accordingly, the applications of WT for promoting forgiveness, gratitude, wisdom and other positive dimensions will be illustrated. The results of this review show that WT yield therapeutic effects on symptoms and distress, but it also promotes psychological well-being. The use of writing can be a standalone treatment or it can be easily integrated as supplement in other therapeutic approaches. This review might help clinician and counsellors to apply the simple instrument of writing to promote insight, healing and well-being in clients, according to their specific clinical needs and therapeutic goals.
