Reliability and validity of the Chinese version of body dysmorphic disorder scale in Chinese college students
Objective Revise the Chinese version of body dysmorphic disorder scale(CBDDS)and test its reliability and validity in Chinese college students.Methods In October 2022,college students were surveyed with the body dysmorphic disorder scale(BDDS),the body image disorders scale(BIDS),the appearance anxiety scale-brief(AAS-B),the Chinese body shame scale(CBSS)and short-depression scale(SDS).Totally 59 college students(sample 1)were subjected to evaluate the popularity degree of the scale,493 college students(sample 2)were subjected to complete item and exploratory factor analysis,457 colle-ges students(sample 3)were subjected to complete the confirmatory factor analysis,totally 89 colleges students(sample 4)were subjected to complete the re-test reliability analysis.SPSS 25.0 software was used for item analysis,exploratory factor analysis,reliability analysis,Pearson correlation analysis.AMOS 24.0 software was used for confirmatory factor analysis,convergent validity analysis.Results(1)The CBDDS was consisted of 3 dimensions including pathological beliefs,appearance anxiety and overgrooming,and the three-factor model fitted well(x2/df=3.14,GFI=0.93,CFI=0.91,TLI=0.91,RMSEA=0.07).(2)The score of CBDDS was positively correlated with the score of BIDS,AAS-B,CBSS and SDS(r=0.41-0.81,all P<0.01).In addition,the composite reliability coefficients were 0.75-0.95 and AVE coefficients were 0.51-0.56.(3)The CBDDS had good internal reliability with Cronbach's α coefficients from 0.75 to 0.94,split-half reliability coefficients from 0.65 to 0.90 and re-test reliability coefficients from 0.71 to 0.91(all P<0.01).Conclusion The CBDDS has acceptable reliability and validity and can be an effective scale for Chinese college students.
