Objectives: To explore the associations between generalized problematic internet use, number of social networks, and appearance schemas. Methods: 216 Portuguese late adolescents (89.3% females), with a mean age of 18.62 years old (SD = .488, range: 18-19) filled in an internet patterns of use questionnaire, the Generalized Problematic Interne Use Scale 2 (GPIUS2) and The Appearance Schemas Inventory-Revised (ASI-R). Results: A total of 99.6% of the students use social networks. Subjects were divided into three groups (group1: 1-2 social networks; group 2: 3 social networks, and group 3: >3 social networks). There was a statistically difference in Motivational Salience scores (ASI-R) for the three groups [F (2, 503) = 6.0, p = .003]. Post-hoc comparisons indicated that the mean score for group 3 (M = 28.29, SD = 4.95) was significantly different from group 1 (M = 26.69, SD =4.55), and from group 2, (M = 26.87, SD =4.95). Generalized problematic internet subscales (Mood Regulation, Self-Deficient Regulation, and Negative Consequences) and total score were significantly correlated with both dimensions of ASI-R: Self-Evaluation Salience (coefficients varied from r = .31** to r = .47**) and Motivational Salience (from r = .14*, to r = .31**). Conclusions: Generalized problematic internet use and the number of social networks are associated with adolescent’s cognitive-behavioural investment in one’s own appearance.
