Confirmation of the Chinese Version of the Problematic Internet Use Questionnaire Short Form (PIUQ-SF)

Although an increasing number of studies have focused on problematic Internet use, numerous measures exist with only modest investigation into their reliability and validity, both within and across different cultures (Király et al. 2015). The most frequently used questionnaire is the Internet Addiction Test (Young 1998). However, its factor structure appears to be unstable (e.g., Fernandez-Villa et al. 2015; Pontes et al. 2014). Koronczai et al. (2011) suggested that a suitable measure should fit six basic requirements. More specifically, it should be (i) comprehensive, that is examining more, possibly all, aspects of problematic Internet use; (ii) as concise as possible, in order to be able to assess the more impulsive population, and to use in time-limited surveys (or having different forms with different length). Such a measure should be (iii) reliable and valid for different methods of data collection (e.g. online, paper-and-pencil self-rating, face-to-face); as well as (iv) for different age groups (e.g. adolescents and adults), and (v) in different cultural settings. Finally, (vi) cut-off scores should be defined on the basis of clinical examination.
