October 2007Vol. 8, No. 9Parent Materials for Preventing Shaken Baby Syndrome

The National Center on Shaken Baby Syndrome has developed new educational materials for parents based on extensive clinical trials with more than 4,000 parents in maternity departments, pediatric offices, prenatal classes, and nurse home visiting programs. In addition to randomized clinical trials, focus groups of parents were used to help develop the latest Period of PURPLE Crying booklet and DVD. PURPLE is the acronym for the characteristics of infant crying:

  • P: Peak of crying
  • U: Unexpected
  • R: Resistant to soothing
  • P: Painlike face
  • L: Long bouts
  • E: Evening crying common

Designed to create a cultural change in the way parents view crying, the materials can help parents understand the frustrating features of the crying that can lead to shaking or other types of abuse.
