This study examines the relationship between social connectedness, FoMO, and subjective well-being among 258 participants, exploring whether FoMO moderates the relationship between social connectedness and subjective well-being. Tools used in the study are Social Connectedness Scale-Revised (SCS-R), Fear of Missing Out Scale (FoMOS) and BBC well-being scale. Statistical analysis was carried out using Jamovi 2.5.6. which included descriptive statistics, correlation and moderation analysis were conducted to assess the direct and indirect effects of social connectedness and FoMO on well-being. Results indicate that fear of missing out moderates the relationship between social connectedness and subjective well-being. These findings highlight the need for interventions that promote meaningful social interactions while addressing the psychological risks associated with FoMO.
