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.
Women and men aged 18 to 40

Sleep Assessment Protocol
BehavioralParticipants will engage in a structured protocol to assess sleep patterns and potential disturbances related to video game usage. This protocol includes: * Completion of diaries: Participants will maintain a sleep diary, video game usage diary, and screen time diary for 14 days to record their activities and sleep quality. * Clinical assessments: At Visit 2, participants will complete questionnaires related to sleep quality and disturbances, administered by a sleep specialist neurologist. * Actigraphy monitoring: Participants will wear an actimeter during the 14-day recording period to objectively measure sleep activity. * Biological sampling: After the 14 days, participants will provide urinary samples for analysis of 6-sulfatoxymelatonin to evaluate melatonin levels.
