The prevalence of nomophobia is growing among adolescents. This study aimed to disentangle the relationship between nomophobia, the fear of missing out, time spent on the phone, sex, and social alienation. Participants, who were 595 students (313 females and 282 males) attending high school during the 2019-2020 academic year, filled out personal information forms and a series of scales involving nomophobia, the fear of missing out, and social alienation. Then, data were analyzed through a moderated mediation analysis. The results showed that the bivariate correlation was significant but not the direct effect of gender on nomophobia; still, other direct effects were significant. The partial indirect effect of the fear of missing out on nomophobia was only significant for females when social alienation was controlled for. In the model where nomophobia was the outcome model, the power values for the time spent on the phone and its interaction with sex were low but high for other factors. Furthermore, the effect size was small for the model where the mediator was the outcome and high for the model that had nomophobia as the outcome. Thus, it is crucial to consider that the motives underlying the fear of missing out and nomophobia differ between the sexes in planning interventions.
