This study aims to explore the association between dysfunctional sleep beliefs and vulnerability to stress-related transient sleep disturbance in people without sleep disturbance. One hundred thirty-two good sleepers and 307 poor sleepers were included in this study. As expected, poor sleepers showed more dysfunctional beliefs than good sleepers on the Dysfunctional Beliefs and Attitudes about Sleep scale-10 item version (DBAS-10). More important, even in good sleepers, DBAS-10 scores positively correlated with the vulnerability to stress-related sleep disturbance as measured by the Ford Insomnia Response to Stress Test. The results suggest that dysfunctional sleep belief is not only a perpetuating factor for chronic insomnia, it may also serve as a risk factor for stress-related transient insomnia.[ABSTRACT FROM AUTHOR]
