This review covers the literature on behavioural and cognitive-behavioural treatments for sleep disturbance in infants, pre-school, and school-age children. Treatment areas are dyssomnias (disorders of initiating, maintaining, or excessive sleep) and parasomnias (behaviours which occur predominantly during sleep). Interventions aimed at preventing sleep disorder through targeting infant sleep patterns are also examined. Controlled experimental studies are the main focus of this review but case studies and clinical reports are also included. It is concluded that, for families willing to undertake behavioural and cognitive-behavioural interventions, some treatments appear effective for some infant and child sleep problems, in the short term at least. The adequacy of current research is discussed, and suggestions for future research are given.
