BACKGROUND Sexting has garnered interest from the public and the scientific community given its ever-increasing presence in adolescents' lives. However, analysis varies depending on the baseline study used. This calls for a standardised sexting instrument that addresses scientific evidence-based recommendations. The primary aim of this study was to develop and validate the structure of a questionnaire that includes the various sexting behaviours and motives. METHOD The sample comprised 1,362 students (51.1% female; 12-18 years old). Participants were randomly split into two halves, controlling for the gender variable (n=681), and exploratory and confirmatory factor analyses were performed. RESULTS Validity of the Sexting Behaviours and Motives Questionnaire (SBM-Q) was confirmed, along with the suitability of the factor structure, internal consistency, and divergent validity. This was also reported by gender. Six dimensions were identified: sending, reasons for sending, receiving, forwarding, victim of forwarding, and reasons for forwarding. CONCLUSIONS The SBM-Q presents good psychometric properties, providing a detailed and consolidated overview of the behaviours that adolescents might engage in when sexting as well as the context in which it occurs.

验证性爱行为和动机问卷（SBM-Q）。

背景技术由于色情活动在青少年生活中的存在与日俱增，因此引起了公众和科学界的兴趣。但是，分析因所使用的基准研究而异。这就要求使用标准化的色情短信工具，以解决基于科学证据的建议。这项研究的主要目的是开发和验证包含各种性别歧视行为和动机的调查表的结构。方法样本包括1,362名学生（女性51.1％； 12-18岁）。将参与者随机分为两半，控制性别变量（n = 681），并进行探索性和确认性因素分析。结果证实了性行为和动机问卷（SBM-Q）的有效性以及因素结构的适用性，内部一致性和有效性差异。性别也有报道。确定了六个维度：发送，发送原因，接收，转发，转发受害者以及转发原因。结论SBM-Q具有良好的心理测量特性，提供了青少年在性交时可能发生的行为及其发生的环境的详细而综合的概述。
