Because the administration of some items required the infant to be in specific states to be administered (e.g., the habituation
package should be administered preferable in the state 1 (deep sleep) or 2 (light sleep) and the orientation package
must be administered while the infant is in an alert state (Brazelton & Nugent, 1995), some could not be completed. The
Lester orientation items are missing in 37 infants and the habituation items were scored for only 98 infants. Consolability
was not scored on 27 infants that did not reach state 6 (crying) during the examination and self-quieting is missing on 23
infants that did not reach state 5 (alert, eyes open and considerable motor activity).
