The purpose of the present study was to evaluate the factor structure of the children's sleep habits questionnaire (CSHQ) when used with preschool and toddler age children. Mothers of 105 children ages 2-5 completed the CSHQ, the child behavior checklist (CBCL), and a sleep diary. Internal consistency for the original subscales on the CSHQ ranged from .55 to .82 and factor analysis resulted in four factors that tap into critical aspects of sleep. The concurrent validity of the revised scales of the CSHQ was adequate. Overall the results from this study suggest a revised factor structure may be more appropriate for use with preschool and toddler age children.
