In their study, Stavropoulos et al. (2023) capitalized on supervised machine learning and a longitudinal design and reported that the User-Avatar Bond could be accurately employed to detect Gaming Disorder (GD) risk in a community sample of gamers. The authors suggested that the User-Avatar Bond is a "digital phenotype" that could be used as a diagnostic indicator for GD risk. In this commentary, our objectives are twofold: (1) to underscore the conceptual challenges of employing User-Avatar Bond for conceptualizing and diagnosing GD risk, and (2) to expound upon what we perceive as a misguided application of supervised machine learning techniques by the authors from a methodological standpoint.
在他们的研究中,斯塔夫罗普洛斯等人(2023年)利用监督式机器学习和纵向设计,并报告称用户-虚拟形象纽带可准确用于在游戏玩家社区样本中检测游戏障碍(GD)风险。作者们认为用户-虚拟形象纽带是一种“数字表型”,可作为GD风险的诊断指标。在本评论中,我们有两个目标:(1)强调将用户-虚拟形象纽带用于概念化和诊断GD风险所面临的概念挑战,以及(2)从方法论角度阐述我们认为作者对监督式机器学习技术的错误应用。
