摘要：AbstractPrevious researches have given strong evidence that sleep related cognitions play an important mediating role in exacerbating insomnia. The aim of the study was to assess psychometric properties of the Turkish version of the Dysfunctional Beliefs and Attitudes about Sleep Scale-16 (DBAS-16). There were total of 373 participants including 198 adults and 175 undergraduates in the sample. Inner consistency coefficient of the scale was 0.82. The RMSEA was 0.08, the CFI was 0.91, and the SRMR was 0.08. Significant correlations were obtained between the DBAS scores and other psychological variables. The brief Turkish version of the DBAS revealed adequate reliability and validity with its original four-factor structure.
