Abstract: Objective To evaluate the psychometric characteristics of the dysfunctional beliefs and attitudes about sleep scale. Methods Totally 218 participants who were diagnosed with primary insomnia and insomnia combided with psychiatric disorders according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and 34 good sleepers were recruited. All participants were measured by Dysfunctional Beliefs and Attitudes about Sleep Scale(DBAS), DBAS-16 and Pittsburgh Sleep Quality Index(PSQI).Thirty of them were remeasured by DBAS after two weeks.Results Five factors were extracted in the DBAS-Chinese Version (CV) by the exploratory factor analysis. Total DBAS-CV score was significantly correlated with DBAS-16 (r=0.86,P<0.01) and PSQI(r=-0.48, P<0.01). DBAS-CV scale had a good discriminant validity as well (P<0.01). The Cronbach's coefficient of DBAS-CV was 0.83. The Cronbach's coefficients of five subscales were 0.42-0.78. The test-retest reliability coefficient was 0.94,and coefficient of each subscales ranged from 0.76 to 0.93 (P<0.01). Revised Chinese Version of DBAS scale had a good discriminant validity as well(P<0.01). Conclusion Revised Chinese Version of DBAS showed good reliability and validity, and it could be used to evaluate dysfunctional beliefs in insomniacs.
