Assessment and Characterization of Sleep Among Video Game Adult Players Without Video Game Use Disorder : a Feasability Study

The primary objective of the SLEEPLAY study is to assess the feasibility of a research protocol investigating the impact of video games on sleep in adults. More specifically, this study aims to identify potential barriers, facilitators of participation, and participant adherence to various measurement tools (such as actigraphy and melatonin assays) to validate the protocol for a larger future study. Additionally, it seeks to optimize the recruitment of regular adult gamers and determine the conditions that will enable better collection of objective sleep data. The relevance of this feasibility study lies in its ability to test and refine the methodology, thereby facilitating future research while minimizing costs and implementation time.

Inclusion Criteria: * Women and men aged 18 to 40 * Signed informed consent form * For regular gamers: playing video games at least 3 times a week in the past 2 years, with IGDT-10 (Ten-Item Internet Gaming Disorder Test) \> 5 * For control group: non-player or occasional player (at least once in the previous year, but less than once a month) Exclusion Criteria: * Night worker * WIth treatment for sleep disorder or interfering with melatonin secretion (betablokers, melatonin supplements,some antidepressants) * Any pathology leading to circadian rythm disorder, neurological or psychiatric disorder * major addiction (any game or gambling disorder) except for coffee and tabacco
