For the Z-Generation, the Internet has become a very important experimentation laboratory for the discovery and validation of their identity. Despite the importance of the process of building the self in the adolescent, there are hardly any validated instruments that measure the self online. The aim of this research was to design and validate the Brief Self Online Scale (SO-8). A total of 843 students (384 boys, 45.6%), with an age range of 10 to 14 years participated. Confirmatory factor analysis (CFA) confirmed the hypothesized model of two correlated factors (Online Self-Perception and Online Idealized Projection), previously obtained through exploratory factor analysis (EFA). The reliability coefficients of Self Online dimensions were adequate. Indicators of convergent validity were obtained, finding significant correlations with self-concept, problematic Internet use, and online emotional intelligence. The SO-8 has adequate psychometric properties to be considered a reliable and valid tool to measure the construct of the Self Online in adolescents.

对于Z代而言，互联网已成为发现和验证其身份的非常重要的实验实验室。尽管在青少年中建立自我的过程非常重要，但几乎没有任何经过验证的工具可以在线测量自我。这项研究的目的是设计和验证简短的自我在线量表（SO-8）。共有843名学生（384名男孩，占45.6％），年龄在10至14岁之间。验证性因子分析（CFA）确认了两个相关因子（在线自我感知和在线理想化投影）的假设模型，该模型先前是通过探索性因子分析（EFA）获得的。自助在线尺寸的可靠性系数是足够的。获得收敛效度的指标，发现与自我概念有显着相关性，有问题的互联网使用和在线情绪智力。SO-8具有足够的心理计量特性，被认为是衡量青少年自我在线构造的可靠和有效工具。
