Background: In recent decades, it has been observed that the literature and research on face-to- face family interventions for caregivers of people with Severe Mental Disorders (SMD) has decreased significantly. However, the use of online interventions with family members of people affected by SMD seems to emerge as a promising complementary strategy to face-to-face care, and although in an incipient and limited way, it is occupying a growing focus of interest in the literature. Objectives: The article presents a brief narrative review of the current landscape of online family interventions aimed at caregivers of people with SMD. The main novelty of the narrative review presented in this article is the breakdown of the different elements and components explored in the limited literature on online interventions, providing a synthesis of the following aspects: Digital interventions in mental health; Components and quality criteria; Research on network interventions; Psychoeducational interventions. Methodology: As this was a narrative review of online family interventions and given the limited literature available, no specific research methodology was used and no specific criteria were established for the selection of the studies included in this review. The methodology used was qualitative. Results and Conclusions: As this is a narrative review, it is not possible to offer specific results or conclusions based on evidences. However, after the review conducted if it is possible to point out these two elements for future research: [1] Online care and support for family members of people with SMD can be a complementary intervention strategy to face-to-face care. [2] The online family intervention format could be incorporated into routine clinical practice in health care services and should be the subject of further research.
