彩票成瘾倾向量表的初步编制及信效度检验

目的 编制适用于中国彩票购买者的成瘾倾向量表(LAS),并对其信效度进行检验.方法 在全国31个省市百余地区随机选取购彩者进行调查,对其中4071名购彩者的量表结果进行项目分析和探索性因素分析EFA,另4167名购彩者测试结果进行验证性因素分析CFA.结果 通过探索性因素分析将10个项目的 LAS量表分成功能损害和情感依赖2个因子,共解释总变异的45.5%;进一步对2个维度的量表结构进行验证性因素分析,验证了该两因素模型具有较好的结构效度(X2/df=13.34;IFI=0.96;CFI=0.96;NFI=0.96;RSMEA=0.054).该问卷的内部一致性信度(r=0.59～0.74)基本符合测量学的要求;效标效度结果显示:高彩票投入群体在功能损害(t=10.77,P<0.01)和情感依赖量表(t=12.96,P<0.001)上的得分均高于低彩票投入群体,差异有显著性.结论 中国彩票成瘾倾向量表的信效度基本上符合心理测量学要求,具有一定的实际应用价值.

The development of lottery addiction scale for Chinese lottery buyers

Objective This study aims to develop a lottery addiction scale (LAS) for Chinese welfare lot-tery buyers. Methods A scale made by authors was applied to 8238 welfare lottery buyers from 31 provinces,one sample of 4071 cases for exploratory factor analysis (EFA) ,and the other 4167 cases for confirmatory factor analy-sis (CFA). Results Through EFA, the scale consisted 10 items established, and it was divided into two factors: functional impairment and emotional dependency. These two factors could explain 45.5% of total variance, The scale was confirmed by CFA (X2/df=13.34 ;IFI=0.96 ;CFI=0.96 ;NFI=0.96 ;RSMEA = 0.054). The internal consistencies of the scale answered to the basic statistic criterion (r=0.59～0.74). Criteria validity shown by higher LAS scores in high expending group than low expending group was also satisfying. Conclusion The LAS has good psychometric features and could be applied to Chinese lottery buyers.
