During the transition to adulthood, emerging adults may experience new geographic distance separating them from their siblings. Digital leisure is common among emerging adults and may serve as a tool for maintaining relationship quality across geographic distance. Using qualitative data, we created individual digital leisure diversity scores for four categories of digital leisure identified from a constructed taxonomy. The sample included 185 college-attending emerging adults (M_age = 20.1, 64.3% male). Analysis of variance indicated dyadic gender differences in social media and gaming. Digital leisure diversity was associated with greater levels of affective and cognitive sibling relationship quality, regardless of sibling dyad gender. The association between digital leisure diversity and cognitive relationship quality was significant for participants who lived closer to their sibling. During the transition to adulthood when new geographic separation is common, digital leisure shows potential as a compensatory activity that may help siblings maintain relationship quality.
