Unable to Switch Off: Fear of Missing Out, Affective Rumination, and Psychological Detachment from Work

The expansion of digital connectivity has reshaped contemporary work environments, increasing flexibility while simultaneously blurring the boundaries between work and personal life. In such contexts, employees may experience difficulties in psychologically detaching from work during off-job time. Drawing on the Effort-Recovery model and Conservation of Resources theory, this study examined whether affective work-related rumination indirectly explained the association between Fear of Missing Out (FoMO) and psychological detachment. A cross-sectional survey was conducted with 228 employees from diverse occupational sectors who completed validated measures of FoMO, affective rumination, and psychological detachment. Indirect effect analyses using bootstrapping procedures indicated that FoMO was positively associated with affective rumination, and affective rumination was negatively associated with psychological detachment. The indirect effect was significant, whereas the direct association between FoMO and detachment was not. These findings are consistent with an indirect association pattern whereby FoMO is related to lower psychological detachment through higher levels of affective rumination. However, given the cross-sectional design, the results should be interpreted as correlational evidence rather than as demonstrating a causal mediation process. The model accounted for approximately 10% of the variance in psychological detachment. Overall, the findings suggest that FoMO may be indirectly related to reduced recovery experiences via emotionally charged repetitive thinking that sustains cognitive activation beyond working hours. Addressing rumination and supporting healthier digital boundary management may therefore represent promising avenues for supporting occupational mental health in increasingly connected work environments.
