大学生手机过当依赖量表的编制与信效度检验

目的:编制用于测量识别非手机成瘾的大学生手机过当依赖量表(MEDS-C),并进行信效度检验。方法:通过综述法与访谈法编制包含30个项目的初步量表,对682名大学生进行施测。经项目分析、探索性因子分析(n=338)与验证性因子分析(n=310)进行结构效度测量,另抽取34名大学生进行间隔时长为2周的前后重测以获得重测信度。结果:通过因子分析获得4因子结构和3因子结构量表,经比较,3因子结构量表与预设结构相符且各项指标拟合度更优。3因子EDMS-C包含突显行为、低效性和安抚性3个维度共9个项目,各因子负荷在0.56~0.83,方差累计解释率为56.48%。量表结构效度良好(χ~2=49.86,df=24,χ~2/df=2.01,RMR=0.05,GFI=0.97,AGFI=0.94,CFI=0.96,RMSEA=0.06);效标效度为0.79;量表内部一致信度不低于其Cronbachα系数0.78,3个因子的系数在0.58~0.77之间;量表总重测信度为0.81,3个因子的重测信度在0.56~0.68之间。结论:本研究编制的大学生手机过当依赖量表具有较好的信效度,可用于筛别大学生中对手机过当依赖的非成瘾者。

Development and Validation of Mobilphone Excessive Dependency Scale for College Students (MEDS-C)

Objective:To develop a mental scale to measure and identify the non-addiction but excessive dependen‐cy on Mobil phone for College Students (EDMS -C) ,and test the scale’s reliability and validity .Methods:According to theoretical analysis and interview ,we proposed the initial scale with 30 items .682 college students’ data were col‐lected in sum .The scale was first revised through item analysis ,then the construct validity of scale was tested by ex‐ploratory factor analysis(n=338)and confirmatory factor analysis (n=310) ,the retest reliability was tested by 2 weeks apart with other 34 students .Results:Through the EFA and CFA ,4 factors and 3 factors scales were produced . By comparing ,3 factors scale not only consisted with hypothesis but also had better indicators .The final EDMS -C contains 9 items belonged to 3 dimensions :Highlight behavior ,inefficiency and comfort .The range of factor loading was between 0 5.6-0 8.3 ,and 60 6.2% of the total variance could be explained .The scale also had satisfying structure validity(χ2 =49 8.6 ,df=24 ,χ2/df=2 0.1 ,RMR=0 0.5 ,GFI=0 9.7 ,AGFI=0 9.4 ,CFI=0 9.6 ,RMSEA=0 0.6) ,and it's criterion validity was 0 .79 .The total internal consistency reliability was higher than Cronbach α(0 .78 ) ,the Cronbachαfor each factor ranged from 0 5.8 to 0 7.7 .The total retest reliability was 0 8.1 ,the retest reliability of each factor ranged from 0 5.6 to 0 .68 .Conclusion:It suggests the scale of Mobil phone excessive dependency for college students has satisfactory reliability and validity ,can be used to identify the students who are non-addiction but ex‐cessive dependency on mobilphone .
