Intervention package for treating sleep disorders in a four-year-old girl.

The study describes an intervention package for the treatment of sleep disorders in a 4-year-old girl, using a multiple-baseline design. The subject's sleep disorders included several undesirable habits: never going to sleep in her own bed; waking up several times during the night, screaming and shouting for hours; and entering her parents' bed and insisting on staying there. The intervention package was carried out with the parents, the child, and her sister. It was based on the disconnection of the contingencies between behavior and outcome; rewards; praise; and time-out. The whole process was terminated in 8 weeks, and maintenance levels were assessed via follow-up after three and six months.
