Social Media Disorder (SMD) is characterised by the intense and excessive use of social media. Although previous studies have shown that SMD was associated with poor mental health, research across types of usage and platforms remain limited. Here, we conducted an initial investigation of social media usage across platforms and its relation to anxiety, sleep and loneliness in female adolescents. Forty one 16- to 19-year-old British female adolescents were administered online questionnaires. Intensity of social media activity across Facebook, Instagram, Snapchat and Twitter was measured with the Social Media Disorder Scale. Anxiety was indicated by the Beck Anxiety Inventory Trait, loneliness was examined via a short three-point questionnaire and sleep quality was measured via both the Pittsburgh Sleep Quality Index and self-reported seven-day sleep diaries. Results showed that, compared to those without SMD, users with SMD experienced elevated levels of loneliness and had less sleep on average, and during the weekdays in particular. Only frequency of posting on Facebook, but not general usage, was associated with poorer sleep quality. These preliminary findings showed that social media disorder across platforms and usage could potentially have different associations to mental health and sleep.

社交媒体障碍 (SMD) 的特点是强烈和过度使用社交媒体。尽管先前的研究表明，SMD 与不良的心理健康有关，但跨使用类型和平台的研究仍然有限。在这里，我们对跨平台社交媒体的使用及其与女性青少年的焦虑、睡眠和孤独感的关系进行了初步调查。对 41 名 16 至 19 岁的英国女性青少年进行了在线问卷调查。Facebook、Instagram、Snapchat 和 Twitter 上的社交媒体活动强度是用社交媒体障碍量表测量的。贝克焦虑量表特征表明焦虑，通过简短的三点问卷调查孤独感，并通过匹兹堡睡眠质量指数和自我报告的 7 天睡眠日记测量睡眠质量。结果表明，与没有 SMD 的人相比，患有 SMD 的用户的孤独感水平更高，平均睡眠时间更少，尤其是在工作日。只有在 Facebook 上发帖的频率，而不是一般使用，与较差的睡眠质量有关。这些初步研究结果表明，跨平台和使用社交媒体的障碍可能与心理健康和睡眠有不同的关联。但不是一般使用，与较差的睡眠质量有关。这些初步研究结果表明，跨平台和使用社交媒体的障碍可能与心理健康和睡眠有不同的关联。但不是一般使用，与较差的睡眠质量有关。这些初步研究结果表明，跨平台和使用社交媒体的障碍可能与心理健康和睡眠有不同的关联。
