Social media use disorder (SMUD) is associated with substantial impairments in daily functioning, and adolescents are particularly at risk. The 11th revision of the International Classification of Diseases (ICD-11) criteria of gaming disorder (GD) could be shown to be suitable to describe SMUD in adolescents. Since adolescents' insight might be limited due to young age or symptom denial, it is essential to include their parents in the diagnostic process. The development and validation of a parental scale are, therefore, of great interest to clinicians and scientists. The Social Media Use Disorder Scale for Parents (SOMEDIS-P) was developed by clinical experts and validated in 944 parent–child dyads. Adolescents were 10–17 years old and frequently used social media (SM). Besides SM use times, standardized questionnaires were applied to assess SM use patterns according to ICD-11 and Diagnostic and Statistical Manual of Mental Disorders-5 criteria of (Internet) GD, psychological stress, and depressive symptoms in an online survey. Item structure was investigated by confirmatory factorial analysis. Receiver operating characteristic curve analyses to determine cutoff values and accordance with adolescent self-ratings were computed. A presumed two-factorial structure of SOMEDIS-P could be confirmed describing cognitive-behavioral symptoms and negative consequences. The instrument showed good to excellent internal consistency and criterion validity with moderate to strong correlations, excellent discriminatory characteristics, and moderate accordance with the adolescents' self-ratings. As the first successfully validated tool for the assessment of ICD-11-based SMUD in adolescents by parental judgment, SOMEDIS-P can make an important contribution to reliable SMUD screening in clinical practice and research.

基于国际疾病分类 11 的青少年社交媒体使用障碍外部评估：家长社交媒体使用障碍量表的开发和验证

社交媒体使用障碍 (SMUD) 与日常功能的严重损害有关，青少年尤其处于危险之中。国际疾病分类 (ICD-11) 游戏障碍 (GD) 标准的第 11 次修订版可能被证明适合描述青少年的 SMUD。由于青少年的洞察力可能由于年龄小或症状否认而受到限制，因此必须让他们的父母参与诊断过程。因此，临床医生和科学家对父母量表的开发和验证非常感兴趣。父母社交媒体使用障碍量表 (SOMEDIS-P) 由临床专家开发，并在 944 名亲子二人组中得到验证。青少年年龄在 10-17 岁之间，经常使用社交媒体 (SM)。除了SM使用次数，精神疾病诊断与统计手册-5在线调查中（互联网）GD、心理压力和抑郁症状的标准。通过验证性因子分析研究项目结构。计算接受者操作特征曲线分析以确定截止值并根据青少年自我评价。可以确认 SOMEDIS-P 的假定双因素结构描述认知行为症状和负面后果。该工具显示出良好至极好的内部一致性和标准效度，具有中等至强的相关性、极好的判别特征，并且与青少年的自我评价适度一致。作为第一个成功验证的通过父母判断评估青少年基于 ICD-11 的 SMUD 的工具，
