To better understand the effects of social media use on adolescents' psychosocial functioning, this study examined the temporal stability of social media effects across two separate 3‐week experience sampling methodology (ESM) studies conducted 6 months apart in 2019 and 2020. Participants were 297 adolescents (Mage = 14.1 years, SD = 0.7, 58.9% girls; 41.1% boys; 0.1% other; 97% Dutch) who completed 126 momentary questionnaires on social media use, affective well‐being, self‐esteem, and friendship closeness in each of the two ESM studies. The effects of social media on psychosocial functioning had low rank‐order stability (r = .05–.25). Findings indicated that the effects of social media use varied not only between individuals but also changed substantially within individuals over time.

变化还是稳定？青少年使用社交媒体对心理社会功能的影响


为了更好地了解社交媒体使用对青少年社会心理功能的影响，本研究在 2019 年和 2020 年间隔 6 个月进行的两项独立的 3 周体验抽样方法 （ESM） 研究中检查了社交媒体影响的时间稳定性。参与者是 297 名青少年 （Mage = 14.1 岁，SD = 0.7,58.9% 女孩;41.1% 男孩;0.1% 其他;97% 荷兰人），他们在两项 ESM 研究中完成了 126 份关于社交媒体使用、情感幸福感、自尊和友谊亲密度的瞬时问卷。社交媒体对社会心理功能的影响具有低等级顺序稳定性 （r = .05–.25）。研究结果表明，社交媒体使用的影响不仅因人而异，而且随着时间的推移，个人内部也会发生重大变化。
