The aim of the present study was to develop a valid and reliable Videogame Addiction Scale for Children (VASC). The data were derived from 780 children who completed the Videogame Addiction Scale (405 girls and 375 boys; 48.1% ranging in age from 9 to 12 years). The sample was randomly split into two different sub-samples (sample 1, = 400; sample 2, = 380). Sample 1 was used to perform exploratory factor analysis (EFA) to define the factorial structure of VASC. As a result of EFA, a four-factor structure comprising 21 items was obtained and explained 55% of the total variance (the four factors being "self-control," "reward/reinforcement," "problems," and "involvement"). The internal consistency reliability of VASC has found 0.89. Confirmatory factor analysis (CFA) was performed to confirm the factorial structure obtained by EFA in the remaining half of sample ( = 390). The obtained fit indices from the CFA confirmed the structure of the EFA. The 21-item VASC has good psychometric properties that can be used among Turkish schoolchildren populations.
本研究的目的是开发一种有效且可靠的儿童电子游戏成瘾量表（VASC）。数据来自780名完成电子游戏成瘾量表的儿童（405名女孩和375名男孩；48.1%的年龄在9至12岁之间）。样本被随机分为两个不同的子样本（样本1，n = 400；样本2，n = 380）。样本1用于进行探索性因素分析（EFA）以确定VASC的因子结构。作为EFA的结果，获得了一个由21个项目组成的四因素结构，解释了总方差的55%（这四个因素分别是“自我控制”、“奖励/强化”、“问题”和“参与”）。VASC的内部一致性信度为0.89。进行验证性因素分析（CFA）以在另一半样本（n = 390）中确认EFA获得的因子结构。CFA获得的拟合指数证实了EFA的结构。21项的VASC具有良好的心理测量特性，可用于土耳其学童群体。
