Meditation is widely recognized for its benefits on both physical and psychological health and more particularly on the prevention of depression relapse. However, despite a lot of literature showing its efficacy, the mechanisms of action underlying its benefits have yet to be specifically identified and empirically tested.

to understand these mechanisms actions, it is essential to distinguish meditative practices. Three different categories of meditation can be distinguished: "Attention Family", "Constructive Family" and "Deconstructive Family" with specific effects for each.

The aim of the study is to compare effects of two types of meditation (focused attention and contemplation) on non-attachment to the self and identity threat.
