METHOD
To achieve our goal, we opted for the scoping review method. Scoping reviews are considered “an ideal tool to determine the scope or coverage of a body of literature on a given topic and give clear indication of the volume of literature and studies available as well as an overview (…) of its focus”.10 Moreover, this relatively new method is the preferred option when the research aim is to identify main characteristics of a certain topic based on an existing body of literature.10,11 This scoping review will be conducted in accordance with the scoping methodology proposed by Arksey and O’Malley in 2005.12
