We describe the development, preliminary psychometric properties, and cross-validation of the Behavioral Evaluation of Disorders of Sleep (BEDS: Schreck 1997/1998). Parental reports of problem sleep behavior in elementary school aged children 5 years to 12 years were collected for two samples. With the first sample, an exploratory factor analysis of parental responses (N = 307) resulted in reports of five distinct types of sleep problems: Expressive Sleep Disturbances; Sensitivity to the Environment; Disoriented Awakening; Sleep Facilitators; and Apnea/Bruxism. Four of these factors (Expressive Sleep Disturbances; Sensitivity to the Environment; Disoriented Awakening; and Apnea) were confirmed with the new participant sample (N = 1054). These factors of problem sleep behavior were similar to findings in other studies, with the exception of the exclusion of bedtime behavior problems.
