Online social support as a mode of psychosocial intervention: a review of scientific literature, avenues for future research, and recommendations for practitioners

Objective: The goal of this review is to present online social support interventions described in recent scientific literature, in order to (i) guide organizations wishing to develop such an intervention or to improve an existing program, and (ii) to identify future research directions and recommendations for practitioners. Methods and results: 59 peer-reviewed articles presenting online social support interventions (2006-2016) were analyzed by using a thematic grid focusing on theoretical perspectives on social support, the online platforms used and their functionalities, the process of intervention development and evaluation, the modalities of participation and the facilitation methods, the documented impacts of interventions, and finally future research directions and recommendations for practitioners. A narrative methodology was used to identify challenges in intervention development and implementation, in order to provide guidance to organizations who want to develop or improve their online social support services. Conclusions: Several research directions and recommendations for the development of online social support interventions are suggested, including the need to develop theoretical models of online social support and enrich traditional models of social support, the need to understand the benefits associated with different levels of participation, the importance of needs assessment in the development of interventions, and the contribution of qualitative methods to the evaluation of interventions.
