In this review, we systematize work on the relationship between social media use and stress by providing a functional perspective that distinguishes between three functions that social media can have in the stages of the stress-coping process: as stressors, as resources, and as coping tools. Current research provides evidence that social media can cause stress, serve as resources, and can be used as a tool for various coping strategies, but it remains unclear when social media can successfully mitigate stress. Future research should use more fine-grained research designs that consider the timing of social media use, the situational context, and the encountered content to determine when social media serves which function and when social media reduces or increases stress.
Keywords: Coping; Coping tool; Social media; Stress; Stressor.
