Abstract: 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.
