Background: In the past decades, there was a worldwide increase in people playing video games. Researchers have started to conduct studies and identified positive and negative associations with video gaming. Comparable studies have been done.   Aim: The aim is to analyse, if there is an association between the average hours an adult participant has played computer games per day and depression or social phobia.   Methods: Data from 4,936 adults who voluntarily participated in an online survey which was posted in the forum ‘www.reddit.com’ has been analysed. The survey included two verified Scales (CES-D and SPIN). Multiple linear regression was applied to test for significance respectively for each sex and after adjusting for other variables.   Results: More than 56% of the participants were above the suggested cut-off scores of the CES-D Scale and more than 44% of the SPIN Scale. Positive associations were found between ‘Computer Gaming Hours’ and the outcomes ‘Depression’ and ‘Social Phobia’ in the total population. After stratifying for gender, no associations were found in all groups in the variable ‘Gender’ towards the outcome ‘Depression’. However, a positive association was found towards the outcome ‘Social Phobia’ for ‘males’ and ‘females’.   Conclusions: The findings are not generalizable. Researcher need to investigate the differences between the results of this study compared to other studies, as well as the high prevalence of depression and social phobia among the participants. Additionally, more studies need to investigate, if having a depression or social phobia can lead to increased video gaming hours.
