身分泡泡對Facebook使用者幸福感的影響

Abstract

隨著社群媒體深度滲透人際互動與心理生活，使用者在 Facebook 等平台中所形塑的資訊環境與社交結構，已不再僅是溝通工具，而成為影響其幸福感的重要心理機制。其中，「身分泡泡」（Identity Bubble）作為一種由演算法與選擇性交往所驅動的同質性社交現象，逐漸被認為是促發數位時代焦慮、孤獨與情緒困擾的重要心理根源，卻也可能在特定條件下提供歸屬感與情感慰藉，展現其雙面性特質。然而，過去對身分泡泡的研究多聚焦於政治極化與資訊過濾，對其如何影響個體心理福祉的內在歷程尚缺乏系統實證。因此，本研究以「社會—個人」雙重路徑為理論基礎，釐清 Facebook 使用行為如何透過社會連結與自我揭露，分別影響社會幸福感與主觀幸福感，並進一步檢驗身分泡泡與自我價值兩項心理變數的中介角色。實證資料來自Facebook 使用者問卷調查，有效樣本共 279 份，並採用偏最小平方法結構方程模型（PLS-SEM）進行分析。研究結果顯示：社會連結會透過身分泡泡正向影響社會幸福感，自我揭露則透過自我價值顯著提升主觀幸福感；兩者皆具顯著中介效果。此一結果指出：社群媒體中的同質性互動與認同機制，對個體的情感歸屬與自我認可具有深遠影響，身分泡泡不僅為風險因子，也可能是幸福感的重要心理資源。

As social media becomes deeply embedded in everyday life, platforms like Facebook no longer serve merely as tools for communication but as psychological environments that shape users’ emotional well-being. One emerging concept—the identity bubble—captures the algorithm-driven and self-selected homogeneity of online social networks. This phenomenon, while offering emotional comfort and a sense of belonging, has also been linked to rising anxiety, social isolation, and emotional polarization in the digital era. Yet, empirical understanding of how identity bubbles influence users’ well-being through psychological processes remains limited.This study adopts a dual-pathway framework—“social” and “personal” routes—to examine how Facebook users experience social and subjective well-being. Specifically, it investigates how social connection and self-disclosure contribute to well-being outcomes through the mediating roles of identity bubble and self-worth. A total of 279 valid responses were collected via an online survey and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM).The results reveal that social connection positively influences social well-being through the identity bubble, while self-disclosure enhances subjective well-being via increased self-worth. Both mediators show significant indirect effects, indicating that psychological mechanisms of group recognition and self-affirmation play a central role in the formation of well-being on social platforms.
