Signs of reactive attachment disorder and disinhibited social engagement disorder at age 12 years: effects of institutional care history and high-quality foster care
Open accessAbstract
Two disorders of attachment have been consistently identified in some young children following severe deprivation in early life: reactive attachment disorder and disinhibited social engagement disorder. However, less is known about whether signs of these disorders persist into adolescence. We examined signs of reactive attachment disorder and disinhibited social engagement disorder at age 12 years in 111 children who were abandoned at or shortly after birth and subsequently randomized to care as usual or to high-quality foster care, as well as in 50 comparison children who were never institutionalized. Consistent with expectations, those who experienced institutional care in early life had more signs of reactive attachment disorder and disinhibited social engagement disorder at age 12 years than children never institutionalized. In addition, using a conservative intent-to-treat approach, those children randomized to foster care had significantly fewer signs of reactive attachment disorder and disinhibited social engagement disorder than those randomized to care as usual. Analyses within the ever institutionalized group revealed no effects of the age of placement into foster care, but number of caregiving disruptions experienced and the percentage of the child's life spent in institutional care were significant predictors of signs of attachment disorders assessed in early adolescence. These findings indicate that adverse caregiving environments in early life have enduring effects on signs of attachment disorders, and provide further evidence that high-quality caregiving interventions are associated with reductions in both reactive attachment disorder and disinhibited social engagement disorder.

Each contradiction between two passages listed here was confirmed by an independent check.
Disinhibited-behavior result is called significant despite its reported p-value
MinorThe reported p=.091 is above the conventional .05 threshold, but the next sentence calls the group difference significant. The reported Wald statistic of 6.73 with one degree of freedom also appears inconsistent with p=.091, so the result needs correction.
“There was also an effect of group on disinhibited social behavior (Wald χ2=6.73, df=1, p=.091).”
“The care as usual group (M=1.81, SE=0.30; 95% CI [1.30, 2.52]) had significantly higher scores than the foster care group (M=0.92, SE=0.18; 95% CI [0.63, 1.36]).”
Boys-only analysis switches the stated outcome
MinorThis boys-only analysis follows a discussion of disinhibited social behavior, but its result is labeled as inhibited social behavior. The same paragraph describes the girls' and boys' estimates as group differences for the disinhibited outcome.
“The analysis was re-conducted within boys only, and there was a significant effect of group on inhibited social behavior (Wald χ2=8.53, df=1, p=.003).”
“The possibility for a group × sex interaction was examined; however the model was unable to compute an estimate because all never institutionalized females had scores of 0.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-04.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-04.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
