Abstract:  Electronic game-playing has been linked to adjustment problems in player subgroups. This study examined relationships among time commitment, gender, preference for violent games, and self-concept in 364 4th and 5th graders. Main effects were identified for game preference and gender, with stronger preference for violent games being associated with lower self-perceived behavioral conduct. Implications for future research are discussed. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
