The social support and safety perceived by higher education students are known to be associated with mental health indicators, improving outcomes in emotional, social, and academic aspects. This study analyzed the validity evidence of a multidimensional scale of perceived social support and safety at the university, based on its internal structure and relationships with external variables. We also tested an explicative model between social support and safety perception at university to explain student achievement. Data was collected at a Brazilian public university, from which 3,484 students participated. Both scales have shown to be promising for evaluating the perceived social support and safety of students. The model indicates the centrality of professors’ support to promote students’ safety and achievement perceptions.

众所周知，高等教育学生所感知的社会支持和安全与心理健康指标有关，可以改善情绪，社会和学术方面的结果。这项研究基于其内部结构和与外部变量的关系，分析了大学感知​​到的社会支持和安全的多维尺度的有效性证据。我们还测试了社会支持和大学安全感之间的解释性模型，以解释学生的成绩。数据是从巴西的一所公立大学收集的，共有3,484名学生参加。这两种量表都显示出对评估学生所感知的社会支持和安全性的希望。该模型表明了教授支持以促进学生的安全和成就感为中心的重要性。
