ABSTRACT
Given the widespread use of the Internet, researchers have begun to examine the personal and social consequences associated with excessive online involvement. The present study examined college students' problematic Internet use (PIU) behaviors within the framework of Jessor and Jessor's (1977) problem-behavior theory. Its specific aim was to investigate the links between PIU with both internalizing (depression, social anxiety) and externalizing (substance use and other risky behaviors) problems. Relevant variables from the perceived environmental system, the personality system, and the behavioral system were entered in a canonical correlation analysis. The analysis yielded two distinct functions: the first function, titled traditional problem-behavior syndrome, characterized students who are impulsive, hold socially deviant attitudes and show a propensity to use tobacco and illicit drugs. The second function, titled problematic Internet-behavior syndrome, characterized students who are socially anxious, depressed, report conflictive family relations, and show a propensity toward PIU. Thus, PIU did not share the characteristics typically associated with the traditional problem-behavior syndrome consistent with problem-behavior theory, but showed correlates more consistent with internalizing rather than externalizing problems.
