NUNES DA FONSECA, Patricia et al. Scale of problematic internet use in university students: evidence of validity and reliability. Cienc. Psicol. [online]. 2018, vol.12, n.2, pp.223-230. ISSN 1688-4094.

The objective of these two studies was to gather evidence of the validity and precision of the Scale of Problematic Internet Use. In Study 01, 240 university students, with an average age of 22.96 years (SD = 3.45), answered scale and sociodemographic questions. The results of an exploratory factor analysis indicated a one-dimensional structure, explaining 49.01% of the total variance and comprising eight items, with a Cronbach's alpha of .84. In Study 02, 235 university students, with an average age of 23.95 years (SD = 6.67), responded to the same instruments. Using confirmatory factor analysis, the structure can be confirmed and presents excellent fit indicators: CFI = .99, TLI = .99, RMSEA = .03 (90% CI = .00-.07) and Pclose = .72, in addition to a Cronbach's alpha of .82. It was concluded that the instrument presents evidence of validity and precision and can be used to gauge the problematic use of the Internet and investigate its relationships to the study population
