Abstract

Background: Children reared in institutions experience elevated rates of psychiatric disorders. Inability to form a secure attachment relationship to a primary caregiver is posited to be a central mechanism in this association. We determined whether the ameliorative effect of a foster care (FC) intervention on internalizing disorders in previously institutionalized children was explained by the development of secure attachment among children placed in FC. Second we evaluated the role of lack of attachment in an institutionalized sample on the etiology of internalizing disorders within the context of a randomized trial. Methods: A sample of 136 children (aged 6–30 months) residing in institutions was recruited in Bucharest, Romania. Children were randomized to FC ( n = 68) or to care as usual (CAU; n = 68). Foster parents were recruited, trained, and overseen by the investigative team. Attachment security at 42 months was assessed using the Strange Situation Procedure, and internalizing disorders at 54 months were assessed using the Preschool Age Psychiatric Assessment. Results: Girls in FC had fewer internalizing disorders than girls in CAU (OR = 0.17, p = .006). The intervention had no effect on internalizing disorders in boys (OR = 0.47, p = .150). At 42 months, girls in FC were more likely to have secure attachment than girls in CAU (OR = 12.5, p < .001), but no difference was observed in boys (OR = 2.0, p = .205). Greater attachment security predicted lower rates of internalizing disorders in both sexes. Development of attachment security fully mediated intervention effects on internalizing disorders in girls. Conclusion: Placement into FC facilitated the development of secure attachment and prevented the onset of internalizing disorders in institutionalized girls. The differential effects of FC on attachment security in boys and girls explained gender differences in the intervention effects on psychopathology. Findings provide evidence for the critical role of disrupted attachment in the etiology of internalizing disorders in children exposed to institutionalization.

  • Foster care intervention was associated with greater odds of developing a secure attachment relationship.

    “Foster care intervention was also associated with greater odds of developing a secure attachment relationship (McLaughlin et al., 2012;Smyke et al., 2010)”

    From Resilience following severe early life neglect: A review of longitudinal evidence from the Bucharest Early Intervention Project (2026) · cites this paper as McLaughlin et al., 2012

    The Results (Intervention Effects on Attachment; page not supplied) report greater odds of becoming securely attached from baseline to 42 months for girls in foster care than for girls receiving care as usual (OR=6.6, p=.029). The same comparison was not statistically significant for boys (OR=2.2, p=.250), so the unqualified claim extends beyond the reported finding. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Foster care intervention was linked to fewer internalizing symptoms during childhood and adolescence, particularly among girls.

    “foster care intervention was linked to fewer internalizing symptoms during childhood and adolescence, particularly among girls (Bick et al., 2015;Humphreys et al., 2020;King et al., 2023;McLaughlin et al., 2012).”

    From Resilience following severe early life neglect: A review of longitudinal evidence from the Bucharest Early Intervention Project (2026) · cites this paper as McLaughlin et al., 2012

    The Results (Intervention Effects on Psychopathology; page not provided) report fewer internalizing symptoms in girls assigned to foster care than in girls receiving care as usual, but no such effect in boys. The Methods (Assessment; page not provided) place the psychiatric assessment at 54 months, so this paper does not support the claim's extension to adolescence. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Foster care intervention was associated with weak improvements in internalizing symptoms for boys and strong improvements for girls.

    “Strong improvements in attachment disorder symptoms; moderate improvements in externalizing symptoms and adaptive functioning; weak improvements in internalizing symptoms for boys (strong for girls)”

    From Resilience following severe early life neglect: A review of longitudinal evidence from the Bucharest Early Intervention Project (2026) · cites this paper as McLaughlin et al., 2012

    The Results (Intervention Effects on Psychopathology) report lower internalizing symptoms in girls receiving foster care, but equivalent levels in boys receiving foster care and care as usual. The paper therefore supports improvement for girls, not the claimed weak improvement for boys. (LLM, conf=0.92)

    Experimental — accuracy not yet measured
  • Foster care intervention in the BEIP is associated with increased quality of attachment.

    “↑ Quality of attachment (McLaughlin et al., 2012;Smyke et al., 2010)”
  • Disruptions in attachment and affective development contribute to high internalizing psychopathology among children raised in deprived early environments.

    “These disruptions in attachment and affective development contribute to high levels of internalizing psychopathology among children raised in deprived early environments.(31, 38–40)”

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.

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.
