Problematic Internet use and psychosocial well-being: development of a theory-based cognitive-behavioral measurement instrument

The paper presents results from an exploratory study that: (1) developed a theory-based measure of PIU and (2) administered the instrument to a sample of undergraduate students to assess the associations among PIU and several psychosocial variables including, depression, self-esteem, loneliness, and shyness. A new instrument, the Generalized Problematic Internet Use Scale (GPIUS) was designed to operationalize Davis's [Computers in Human Behavior, 17 (2001), 187] theoretical construct of generalized PIU. The GPIUS and several measures of psychosocial well-being were administered to 386 undergraduate students. Results from this preliminary study indicate that the GPIUS is both reliable and valid. A factor analysis identified seven unique sub-dimensions of the GPIUS, including: mood alteration, perceived social benefits available online, negative outcomes associated with Internet use, compulsive Internet use, excessive amounts of time spent online, withdrawal symptoms when away from the Internet, and perceived social control available online. All GPIUS subscales were correlated with psychosocial health variables including: depression, loneliness, shyness, and self-esteem. A regression analysis identified several important psychosocial and cognitive-behavioral predictors of negative outcomes associated with generalized PIU. Results also suggest that one's preference for computer-mediated social interaction, as opposed to face-to-face interaction, plays a role in the etiology, development, and outcomes of generalized PIU.
