AB - For emerging adults living alone who face the developmental tasks of achieving physical independence and forming intimacy, SNS can serve as a key channel for emotional communication. This study examined how SNS emotional expressiveness moderates the association between SNS use frequency and loneliness, aiming to identify effective digital communication strategies. Data were collected from 338 emerging adults (aged 20–29). We conducted four regression-based moderation analyses using Hayes' PROCESS Macro Model 1 for each sub-factor of SNS emotional expressiveness: SNS emotional expressive behavior, SNS relationship orientation, SNS emotional expression avoidance, and SNS ambivalent inhibition. The results revealed that both SNS emotional expressive behavior and SNS relationship orientation exerted significant moderating effects. Specifically, the positive association between frequent SNS use and loneliness was strengthened at higher levels of SNS emotional expressive behavior or SNS relationship orientation. In contrast, SNS emotional expression avoidance and SNS ambivalent inhibition did not show moderating effects; instead, higher levels of these two traits were directly associated with lower loneliness. This study discusses emotional-expression-based SNS communication strategies to alleviate loneliness among emerging adults living alone.
