General Description

Dysfunctional Beliefs and Attitudes about Sleep is a 30-item scale assessing various beliefs, attitudes, expectations, and attributions about sleep and insomnia. In the original instrument, subjects are asked to place a mark for each statement on a 10-centimeter horizontal line with poles labeled “strongly agree” and “strongly disagree.” In the Portuguese version, it was used a 10-point Likert scale for each item. Except for Item 23, for which the score is reversed, a higher score indicates a more dysfunctional belief.
