Attention Deficit/Hyperactivity Disorder is a Better Predictor for Problematic Internet use than Depression: Evidence from Germany

Sariyska R, Reuter M, Lachmann B, Montag C

Objective: This study aims to address possible associations between excessive use of the Internet and ADHD and Depression. As most of the studies on this topic were conducted in Asia, the aim of this investigation is to review the literature on this subject from Germany and examine problematic Internet use for potential associations with the propensity for Depression and Attention Deficit/Hyperactivity Disorder (ADHD) in a new, distinct German sample.

Methods: A review of the literature was conducted. Subsequently, a total of N = 895 healthy participants from Germany (413 males, 482 females) took part in a new study. Participants filled in questionnaires on their Internet usage, propensity for depression and ADHD.

Results: The review of the literature revealed predominantly positive associations between problematic Internet use and depression, whereas only one study on the relationship between problematic Internet use and ADHD from Germany was found. The results from the current study showed that male participants had significantly higher scores on the Internet Addiction Test (IA-T) than female participants. Finally, the IA-T scores of the participants were linked to both the propensity for depression (r = .247, p < .01) and ADHD (r = .335, p < .01). This association was stronger for ADHD and in particular for the subscale “attention deficit”, as revealed by a post-hoc analysis.

Conclusion: The results of this study are consistent with most of the research on this topic in other cultural circles and highlight the role of ADHD and depression when it comes to problematic Internet use. This study provides a basis for consideration about the clinical implications and treatment of comorbid problematic Internet use.
