Bayley Scales of Infant and Toddler Development, Fourth Edition (Bayley-4UK)

Most comprehensive assessment tool for determining developmental delays in children.

Bayley Scales of Infant and Toddler Development, Fourth Edition (Bayley-4) assesses infant and toddler development across five scales: Cognitive, Language, Motor, Social–Emotional, and Adaptive Behaviour. Assessment of the Cognitive, Language, and Motor domains is accomplished by administering structured items to the child and engaging the caregiver to support responses where appropriate. The Social-Emotional and Adaptive Behaviour scales are administered via caregiver questionnaire which allows them to share their own observations of the child’s abilities.

Some updates to the Bayley-4 include the reduced number of items and improved workflow as well as new content and updated normative data.

ASSESSMENT SCALES

  • Adaptive Behaviour: listening and understanding, talking, caring for self, relating to others, and playing

  • Cognitive: visual preference, attention, memory, sensorimotor, exploration and manipulation, concept formation

  • Language: receptive and expressive language subtests

  • Motor: fine and gross motor subtests

  • Social-Emotional: communicating needs, self-regulation using emotional signals

AREAS OF APPLICATION

The Bayley-4 can be used to identify developmental strengths, competencies, delays, and weaknesses in small children, assisting practitioners to identify problematic areas and intervene early in the child’s life
