Background
This study aimed to provide an integrated explanation of the effects of rejection sensitivity on loneliness. Specifically, this study examined the individual and serial mediating roles of self-acceptance and self-silencing in the relationship between rejection sensitivity and loneliness.
Methods
A cross-sectional online survey was conducted with 310 male and female university students (ages 19-26 years) in South Korea. Participants completed measures assessing rejection sensitivity, self-acceptance, self-silencing, and loneliness. The collected data were analyzed using SPSS 22.0, and the PROCESS macro was used to test for direct and indirect effects.
Results
Rejection sensitivity had a significant direct effect on loneliness; it was negatively correlated with self-acceptance and positively correlated with self-silencing. Both self-acceptance and self-silencing served as partial mediators in the relationship between rejection sensitivity and loneliness. Critically, the serial mediation model was significant: rejection sensitivity predicted lower self-acceptance, which in turn predicted higher self-silencing, ultimately leading to increased loneliness.
Conclusions
The findings suggest that the influence of rejection sensitivity on loneliness is a complex process partially explained by the sequential roles of diminished self-acceptance and subsequent self-silencing. This study highlights the importance of targeting both self-acceptance and self-silencing in clinical and educational settings to develop effective strategies for reducing loneliness among young adults with high rejection sensitivity.

Abstract PDF
Background
This study aimed to examine the mediating effect of acceptance and the moderated mediation effect of emotional reactivity in the relationship between awareness and state anxiety.
Methods
A total of 395 Korean adults participated in this study. Participants completed self-report measures of awareness, state anxiety, acceptance, and emotional reactivity. Data were analyzed using PROCESS macro to test for mediation and moderated mediation effects.
Results
The findings indicated that acceptance significantly mediated the relationship between awareness and state anxiety. Moreover, emotional reactivity significantly moderated the association between awareness and acceptance. A significant moderated mediation effect was also observed, suggesting that the indirect effect of awareness on state anxiety through acceptance differed depending on levels of emotional reactivity.
Conclusions
These results elucidate the mechanisms underlying mindfulness, indicating that its anxiety-reducing effects via acceptance depend on individual differences in emotional reactivity. The study offers suggestions for the clinical application of mindfulness-based interventions, emphasizing the importance of tailoring strategies to clients’ emotional sensitivity.
