Loneliness and academic performance mediates the relationship between fear of missing out and smartphone addiction among Iranian university students

Abstract Background Fear of missing out (FoMO) can increase loneliness and smartphone addiction and decrease academic performance in university students. Most studies investigated the relationship between FoMO and smartphone addiction in developed countries, and no studies were found to examine this association in Iran. The mediating role of loneliness and academic performance in the relationship between FoMO and smartphone addiction is unclear. This study investigated the relationship between FoMO and smartphone addiction and the mediating role of loneliness and academic performance in this relationship in Iranian university students. Methods In this cross-sectional study, 447 students from Urmia University of Medical Sciences were investigated. Data were collected using demographic questionnaires, Przybylski's FoMO scale, Pham and Taylor's academic performance questionnaire, Russell's loneliness scale, and Kwon's smartphone addiction scale. Data were analyzed using SPSS ver. 23 and SmartPLS ver. 2. Results FoMO had a positive and direct association with smartphone addiction (β = 0.315, t-value = 5.152, p 0.05). FoMO also indirectly correlated with academic performance through students' loneliness (β =—0.368, t-value = 6.377, p
