[Post-traumatic growth: Some conceptual considerations]

Post-traumatic growth (PTG) is a quite new concept of positive psychology proposed in the mid-1990s which is still rather confidential in France. This article aims to propose a full description of this concept from an historical view to epidemiological data through underlying mechanisms and evaluation.

A literature search identifying relevant results was performed through the Pubmed database.

PTG refers to positive psychological changes experienced as a result of a traumatic life event in order to rise to a higher level of functioning. That is to say that people experiencing psychological struggle following adversity may often see positive outcomes in the aftermath of trauma. Domains of PTG include appreciation of life, relationships with others, new possibilities in life, personal strength and spiritual change. A self-report scale, the Post-Traumatic Growth Inventory (PTGI), has been developed. PTG has been demonstrated after various traumatic events such as transport accidents, natural disasters, interpersonal violence or medical problems, with a prevalence ranging from 3 to 98 % depending on the type of trauma.

The concept of resilience and some evaluation bias may have been deleterious for the development of the PTG concept in the French-speaking world. There is a need to consolidate data to understand the pathway leading to PTG, noticeably to identify factors contributing to PTG that can help to promote the growth as a new therapy for trauma.
