A CONSORT flow diagram. B Experimental design. a. Timeline of sleep groups: Participants were split into two groups (SIG and SCG) and spent two consecutive nights in the sleep laboratory. SIG participants were exposed to approximately 300 game-related sounds per night, while SCG participants heard around 300 non-game-related sounds. Online game craving questionnaires and cue reactivity tasks were administered before and after the intervention. b. Timeline for awake groups. Participants were divided into two groups (AIG and ACG), On day 1, they completed online game craving questionnaires, a cue reactivity task, and a 50-min cue-exposure intervention (approximately 300 game-related sounds for AIG and 300 non-game-related sounds for ACG). On day 2, the cue-exposure intervention was repeated. On day 3, participants took the cue reactivity task and completed the craving questionnaires again. All four groups then filled out the online game craving questionnaires at 1 (T2), 2 (T3), 3 weeks (T4), and at 1 month (T5) post-intervention follow-up. Participants returned to the laboratory for the cue reactivity task 1 month later. SIG, sleep intervention group; SCG, sleep control group; AIG, awake intervention group; ACG, awake control group.
