The gap between the demand and delivery of mental health services in mainland China can be reduced by validating freely available psychometrically sound psychological instruments. present research examined Chinese version 21-item Depression Anxiety Stress Scales (DASS-21). Study 1 administered DASS-21 to 1,815 college students found internal consistency indices (Cronbach's alpha) .83, .80, .82 for Depression, Anxiety, subscales, respectively, .92 total DASS total. Test-retest reliability over a 6-month interval was .39 .46 each 3 subscales DASS. Moderate convergent validity demonstrated via significant correlations with Beck Inventory (r = .51 at Time r .64 2) State-Trait .41), respectively. Confirmatory factor analyses supported original 3-factor model minor change (nonnormed fit index [NNFI] .964, comparative [CFI] .968, root mean square error approximation [RMSEA] .079). 2 clinical utility 166 patients schizophrenia 90 matched healthy controls. Patients had higher but not subscale scores than A discriminant function composed linear combination correctly discriminated 69.92% participants, which again potential China. Taken together, findings these studies support cross-cultural (PsycINFO Database Record
