The purpose of the study is to determine the degree of Internet addiction in engineering students. It takes as a theoretical reference the scale proposed by Young (1998), which establish the criteria and ranges of addiction. The instrument is in Likert format with responses ranging from 1 (rarely) to 5 (always). The participants were 306 students of the Engineering career enrolled in the different school grades of the Technological Institute of Tierra Blanca, Veracruz in the 2020-2021 school year. For data analysis, the statistical technique of exploratory factor analysis with extraction of principal components and Varimax rotation is used. In addition, for instruments designed with Likert scales, it is necessary to use the Polychoric Correlation matrices for factor analysis (Richaud, 2005; Ogasawaras, 2011). The main findings are: a factorial structure of six factors was obtained, which explains 63.1 % of the total variance and is in accordance with Young's proposal (1998), however the indicators are integrated differently in each factor. The level of internet addiction of the students does not fall within the normal range; the highest percentage is mild, which does not generate an alert in which immediate attention should be paid. It was also found that there is no difference in internet addiction in relation to gender.
