Do diagnostic patterns exist in the sleep behaviors of normal children?
We investigated the factor structure of the Children's Sleep Behavior Scale in an unselected sample of children (N = 838), ages 6 to 12.5 years, drawn from an elementary school population. Although no factor emerged that corresponded exactly to the parasomnias, as described by the Association of Sleep Disorders Centers (1979), all of the variables that loaded on Factor 1 were behaviors characteristic of the parasomnias, with the exception of recalled nightmares. Variables that were expected to load on this factor, but did not, were sleeptalking, teeth grinding, and enuresis. Enuresis was not related to any of the sleep behaviors assessed, and teeth grinding shared less than 9% of the variance with any of the other variables. Many of the variables loaded on more than one factor. The second factor, which was labeled bedtime resistance, was the only clearly unambiguous factor. Of the five factors that emerged, the third reflected positive affect, the fourth was a motor factor, and the fifth was an anxiety factor. Nightmares loaded on the anxiety factor as well as the first factor. The results of the study offered no support for the category of Disorders of Initiating and Maintaining sleep (DIMS), which has a childhood onset.[1]References
