The problematic Internet use (PIU) has become a topic of special relevance since it is a problem that affects the whole world. It has been detected that the population at greatest risk is university students along with adolescents. At the same time, Spain is one of the countries with the highest PIU rate. The purposes of this article were to analyze the presence and degree of Internet addiction among university students and to check the sociodemographic factors that influence the PIU. To this end, 13 hypotheses were put forward and contrasted using a structural equation model. The study adopted a cross-sectional approach by applying the Internet addiction test to a sample of undergraduate students in southern Spain (n = 1,013). The results indicated a prevalence of PIU among students of almost 12.5% and with a moderate degree of addiction. In turn, the following hypotheses that had a significant effect on the PIU were supported: gender; field of knowledge; living in the parents’ home; Internet daily use for leisure; Internet daily use for academic purposes; number of social networks; sexual orientation; marital status. Finally, the main findings of the study were reviewed, and the main recommendations and implications for mitigating the negative effects of technology and enhancing the positive ones were established.

有问题的互联网使用（PIU）已成为一个特别重要的话题，因为它是一个影响整个世界的问题。已经发现，风险最大的人群是大学生和青少年。同时，西班牙是PIU率最高的国家之一。本文的目的是分析大学生中网络成瘾的存在和程度，并检查影响PIU的社会人口统计学因素。为此，提出了13个假设，并使用结构方程模型进行了对比。这项研究采用横断面方法，将网络成瘾测试应用于西班牙南部的大学生样本（n= 1,013）。结果表明，学生中的PIU患病率约为12.5％，且具有中等程度的成瘾性。反过来，以下对PIU产生重大影响的假设也得到了支持：性别；知识领域；住在父母的家中；日常上网休闲 日常用于学术目的的互联网；社交网络的数量；性取向；婚姻状况。最后，对研究的主要发现进行了回顾，并确定了减轻技术负面影响和增强正面负面影响的主要建议和含义。
