The Generalized Problematic Internet Use Scale-2 in a French sample: Psychometric evaluation of the theoretical model

Objectives

The Generalized Problematic Internet Use Scale-2 (GPIUS-2) is a short self-report questionnaire assessing Internet addiction based on a cognitive behavioral model. Our main goal was to evaluate the psychometric properties of its French version among a sample of students and to appraise the relevance of the generalized problematic Internet use model.

Methods

A sample of 563 university students aged between 18 and 35 years (M = 20.8; SD = 2.7) completed several online self-report questionnaires including the GPIUS-2, the Internet Addiction Test (IAT) and the Center for Epidemiologic Study-Depression scale (CES-D).

Results

Confirmatory Factorial Analyses revealed a poor but acceptable overall fit for the original five-factor model and the original four-factor model. Path analyses, testing Structural Equation Modeling provided showed a poor fit to the data, suggesting insufficient construct validity. Convergent and concurrent validities analyzed through correlational analyses revealed significant relationships between the GPIUS-2, its factors, the IAT, time spent online and the CES-D.

Conclusions

This research highlights the insufficient psychometric properties of the GPIUS-2 in a French sample, similar to previous results. However, this French version appears to be a useful multidimensional tool for assessing problematic Internet use among students, and reveals promise for future research and clinical applications of the measure, given its solid theoretical basis and despite the results of this psychometric study.
