Este trabajo tuvo el objetivo de analizar el Fear of Missing Out (FoMO) en adultos de Buenos Aires. Participaron 191 sujetos (79.1% mujeres, 20.4% varones, no binarios 0.5%) de entre 18 y 76 años (M=34.38; DE= 11.86). Se recolectaron datos con una encuesta de datos sociodemográficos, la adaptación local en curso de la Fear of Missing Out Scale (FoMOs; Przybylski et al., 2013), el Big Five Inventory (BFI; Castro Solano & Casullo, 2000; John, 1990) y el Inventario de Evaluación de la Personalidad para DSM-5 Forma Breve (PID-5-BF; Góngora & Castro Solano, 2017; Krueger et al., 2012). Se hallaron asociaciones negativas (p<.05) con la edad tanto para FoMO Estado (r= -.178) como para Rasgo (r= -.196). No se detectaron diferencias según género al comparar hombres y mujeres. Al calcular correlaciones con las variables de personalidad, se obtuvieron asociaciones significativas (p<.05) para FoMO Estado con Agradabilidad (r= -.155), Responsabilidad (r= -.240), Neuroticismo (r= -.232) y Afecto Negativo (r= .217). FoMO Rasgo correlacionó con significativamente (p<.05) con Agradabilidad (r= -.226), Responsabilidad (r= -.289), Neuroticismo (r= -.290), Afecto Negativo (r= .334), Desapego (r= .166); Antagonismo (r= .288), Deshinibición (r= .184) y Psicoticismo (r= .156).

Negative associations (p<.05) with age were found for both FoMO State (r= -.178) and FoMO Trait (r= -.196). No gender differences were detected when comparing men and women. Significant correlations (p<.05) were obtained when calculating correlations with personality variables, including FoMO State with Agreeableness (r= -.155), Conscientiousness (r= -.240), Neuroticism (r= -.232), and Negative Affectivity (r= .217). FoMO Trait correlated significantly (p<.05) with Agreeableness (r= -.226), Conscientiousness (r= -.289), Neuroticism (r= -.290), Negative Affectivity (r= .334), Detachment (r= .166), Antagonism (r= .288), Disinhibition (r= .184), and Psychoticism (r= .156).
