The current study examined the predictors of parent-child relationship qual
ity and developmental change in a sample of children adopted into the U.K.
following severe early privation, and in a comparison sample of nondeprived
, within-country adoptees. One hundred and fifty-eight children adopted fro
m Romania and 52 U.K. adoptees were assessed at age 6 years; longitudinal d
ata (age 4 and 6 years) were available on the 110 Romanian adoptees placed
into U.K. homes before 24 months of age and all U.K. adoptees. Ratings of p
arent-child positivity and negativity during a semistructured interaction t
ask were obtained from coders who were blind to the child's background. Res
ults indicated that adoptive parent-child relationship quality was related
to duration of deprivation and that cognitive/developmental delay mediated
this association. The magnitude of this effect was modest and diminished ov
er time. Longitudinal analyses revealed that positive change in parent-chil
d relationship quality was most marked among children who exhibited cogniti
ve catch-up between assessments, The direction of effects appeared to be pr
imarily child to parent. The findings underscore the need for further resea
rch on the long-term impact of early experiences on psychosocial developmen
t.
