Social change towards inclusion is a very common topic, but progress is slow. Because of its importance in the current educational context, knowing how to speed up this transformation is fundamental. A multiple regression analysis with a transversal quantitative designed survey (n = 245) was conducted. The aim was to identify internal and external factors predicting attitudes towards people with intellectual disability in undergraduate students at the University of Murcia (Spain). According to the expected estimate, the variables ‘empathic concern’ and ‘chosen degree’ predict good attitudes towards people with intellectual disability among university students. On the other hand, external variables such as ‘previous knowledge about disability’ or ‘contact with people with disabilities’ are not explanatory factors. These findings contribute to the existing knowledge about predictive variables for attitudes towards people with intellectual disabilities in the future Spanish education professionals.

面向包容的社会变革是一个非常普遍的话题，但进展缓慢。由于其在当前教育环境中的重要性，了解如何加速这一转变至关重要。具有横向定量设计调查的多元回归分析（n = 245) 进行。目的是确定预测穆尔西亚大学（西班牙）本科生对智障人士态度的内部和外部因素。根据预期估计，变量“移情关注”和“选择程度”预测大学生对智障人士的良好态度。另一方面，诸如“以前对残疾的了解”或“与残疾人接触”等外部变量不是解释性因素。这些发现有助于了解未来西班牙教育专业人士对智障人士态度的预测变量的现有知识。
