摘 要: 目的:编制网络游戏认知-成瘾量表(Internet game cognition-addition scale,IGCAS),并检验其信效度。方法:在165名大学生中先进行试测,确定16个条目的正式版本后以分层整群抽样法,随机抽取广东省在校大学生654名,施测网络游戏认知-成瘾量表和Young量表,考察网络游戏认知-成瘾量表的信度和效度。结果:探索性因素分析结果显示网络游戏认知-成瘾量表涵盖2个维度,游戏非适应认知因子和成瘾行为因子,可解释总方差的61.63%,各条目的因素负荷在0.550-0.850之间。验证性因素分析结果表明二因素模型的拟合指数分别为:χ^2=118.44,NNFI=0.98,NFI=0.98,CFI=0.99,RMSEA=0.087。量表的重测信度r=0.76,P〈0.01,各维度和总量表的α系数为0.901-0.943。网络游戏认知-成瘾量表总分、各维度分与Young的成瘾量表总分呈正相关(r=0.24-0.26,P〈0.01)。结论:IGCAS有良好的信效度,可作为大学生网络游戏成瘾辅助诊断的有效测量学工具。 Objective: To develop Internet game addiction scale ( IGAS ) and examine its applicability in college students of China. Methods: After a pretest in 165 college students for determinating a 16-item version of IGAS, A sample of 654 college students completed/GAS and Chinese version of Young Scale for IAD ( internet addiction disorder) . Reliability and validity of/GAS were analyzed. Results: ( 1 ) The retest reliability, split-half and Cronbach's α reliability coefficients of total scare were 0. 76, 0. 917 and 0. 943, respectively. ( 2 ) Scores of total scale and each subscale were significantly correlated with scores of Young scale at 0. 01 levels (r=0. 24 -0. 26) . (3 ) Two factors were extracted by exploratory factor analysis and explained 61.63% of the total variance, the load of each item varied from 0. 55 to 0. 85. (4) CFA confirmed that standard measurement model fit datum well: Х^2 = 118. 44, NNFI =0.98 , NFI = 0. 98, CFI = 0. 99, RMSEA = 0. 087. Conclusion: Reliability and validity of IGAS is corresponded with psychometric standard, and it could be an effective instrument using in diagnosis of Interuet game addition disorder.
