The vast majority of children adopted from China are female
Items were: child too eager to approach, made personal comments to adults, initiated physical contact with unfamiliar adults
Items were: definite lack of differentiation among adults with respect to the child’s social response to them, clear indication that the child would readily go off with a stranger, definite lack of checking back with parent in anxiety-provoking situations
This article did not provide information about the conditions of these institutions, but other studies from the same authors on the same sample did describe the severity of the deprivation.
Items were: whether the child has developed a preference for a specific caregiver, approaches the caregiver for comfort, responds to comfort when offered, engages in reciprocal social interaction, regulates emotions well
In this study, children moved from an institution to foster care (not an adoptive home) at this age
Items were: whether the child checks back with the caregiver when exploring, shows age-appropriate reticence around strangers, demonstrates willingess to “go off” with a stranger
Items were: child wandered without distress, child would be willing to go home with a stranger, child was friendly to strangers, child was ever shy, what a child typically did upon meeting new adults
This study used time in the orphanage instead of age at adoption; these two variables were correlated at r = .97
