最近，美国精神病学协会将互联网游戏障碍(IGD)列入第五版《精神障碍诊断和统计手册》(DSM-5)的附录中。本研究的主要目的是根据DSM-5的9个标准，检验4种测量工具测量IGD的信度和效度：长(27个条目)和短(9个条目)多分量表和长(27个条目)和短(9个条目)二分量表。这些量表的心理测量学特性在2444名具有代表性的荷兰青少年和成年人中进行了测试，年龄在13-40岁之间。验证性因素分析表明，各量表的结构效度(即维度结构)均令人满意。两种类型的评估(多分和二分)也是可靠的(即，内部一致)，并显示出良好的标准相关效度，与玩游戏的时间、孤独和攻击性呈正相关，与自尊、亲社会行为和生活满意度呈负相关。二分式9项IGD量表显示了坚实的心理测量学特性，是最实用的诊断用量表。对这一二分量表的潜在类别分析表明，可以区分出3个群体：正常游戏玩家、危险游戏玩家和游戏障碍玩家。根据这最后一个群体的人数，荷兰13至40岁人群中IGD的患病率约为4%。如果应用DSM-5诊断阈值(经历5个或更多标准)，则游戏障碍玩家的患病率超过5%。
Recently, the American Psychiatric Association included Internet gaming disorder (IGD) in the appendix of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The main aim of the current study was to test the reliability and validity of 4 survey instruments to measure IGD on the basis of the 9 criteria from the DSM-5: a long (27-item) and short (9-item) polytomous scale and a long (27-item) and short (9-item) dichotomous scale. The psychometric properties of these scales were tested among a representative sample of 2,444 Dutch adolescents and adults, ages 13-40 years. Confirmatory factor analyses demonstrated that the structural validity (i.e., the dimensional structure) of all scales was satisfactory. Both types of assessment (polytomous and dichotomous) were also reliable (i.e., internally consistent) and showed good criterion-related validity, as indicated by positive correlations with time spent playing games, loneliness, and aggression and negative correlations with self-esteem, prosocial behavior, and life satisfaction. The dichotomous 9-item IGD scale showed solid psychometric properties and was the most practical scale for diagnostic purposes. Latent class analysis of this dichotomous scale indicated that 3 groups could be discerned: normal gamers, risky gamers, and disordered gamers. On the basis of the number of people in this last group, the prevalence of IGD among 13-through 40-year-olds in the Netherlands is approximately 4%. If the DSM-5 threshold for diagnosis (experiencing 5 or more criteria) is applied, the prevalence of disordered gamers is more than 5%.
