Toward a comprehensive theory of problematic Internet use: Evaluating the role of self-esteem, anxiety, flow, and the self-rated importance of Internet activities

摘要

Problematic Internet use (PIU) has long been a matter of public concern. Study 1 examined the correlates of a well-validated measure of Internet addiction [Young, K. S. (1998). Caught in the net. New York: John Wiley and Sons] with 315 students (39% male). Hierarchical regression analyses indicated that low self-esteem, unrealistic optimism, and the importance of 7-positive activities (I7PA) all contributed to the prediction of PIU. The inclusion of controls for aspects of Internet uses and demographic characters showed a clear distinction between PIU and frequent Internet use. Subjects who anticipated that negative outcomes were more likely to happen to them than to peers were none-the-less more likely to engage in PIU. The more important positive activities were, the greater the PIU. SEM model suggested that unrealistic optimism was best treated as part of PIU and that low self-esteem and the I7PA were the powerful predictors of PIU. Study 2 tested SEM models of psychosocial characteristics with 279 students (48% male). Anxiety and flow were added as predictors and the felt safety for social contacts was added to Global PIU following Caplan [Caplan, S. E. (2002). Problematic Internet use and psychosocial well-being: Development of a theory-based cognitive-behavioral measurement instrument. Computers in Human Behavior, 18, 553–575]. The more complex model provided excellent fit and showed that low self-esteem, anxiety, and the I7PA were positively related to PIU. The relationship both of flow and sensation-seeking was mediated by the 17PA. Research on the topic has been relatively atheoretical. We propose a theoretical template to guide future research on PIU.
