General Description

The DBAS-SF-16 is a European Portuguese short version of the DBAS designed to differentiate dysfunctional beliefs about sleep and insomnia in clinical and non-clinical settings. It consists of 16 items evaluated on a 10-point Likert scale, ranging from 0 (“strongly disagree”) to 10 (“strongly agree”). This short version of the DBAS includes two factors: Consequences and Helplessness and Medication and Hopelessness.

A cut-off score of 4.3 makes it possible to detect the level of dysfunctional beliefs associated with clinical insomnia, i.e. to identify who may be at risk of developing insomnia.
