Fear of Missing Out and Consumer Happiness on Instagram: A Serial Mediation of Social Media Influencer-Related Activities.

Mounting research shows negative psychological effects for social media and recognizes fear of missing out (FoMO) as a key driver of social media use. This article focuses on social media influencers (SMIs) and investigates potentially positive forms of usage on psychological well-being (i.e., happiness), including how FoMO impacts consumer response to SMIs. A serial mediation model using survey data ( = 604) indicates SMI-related activities are positively associated with a consumer's happiness. Furthermore, SMI-related activities jointly and positively mediate the relationship between FoMO and happiness. Individuals higher in FoMO more frequently visited SMIs' account profiles leading to more frequent purchasing of products recommended by SMIs, which in turn positively influenced happiness. Implications of the findings are discussed with suggestions for future research.
