The Bucharest Early Intervention Project: Case Study in the Ethics of Mental Health Research

Open access
Zeanah, Charles H., Fox, Nathan A., Nelson, Charles A.·2012·Journal of Nervous & Mental Disease

Abstract

The Bucharest Early Intervention Project is the first ever randomized controlled trial of foster care as an alternative to institutional care for young abandoned children. This article examines ethical issues in the conceptualization and implementation of the study, which involved American investigators conducting research in another country, as well as vulnerable participants. We organize the discussion of ethical questions about the study around several key issues. These include the nature and location of the vulnerable study population, the social value of conducting the study, the risks and benefits to participants of participating in the study, and posttrial obligations of the investigators. In discussing how these questions were addressed as the study was designed and after it was initiated, we describe our attempts to wed sound scientific practices with meaningful ethical protections for participants.

TL;DR

This article uses the Bucharest Early Intervention Project (BEIP) as a case study to examine ethical issues in a randomized trial comparing foster care with institutional care for abandoned Romanian children. It describes how the investigators addressed vulnerability, social value, risk-benefit, and post-trial obligations while reporting that foster care generally improved outcomes, with timing effects in some domains.

Key findings

  • BEIP randomized 136 children aged 6–31 months from all six Bucharest institutions: 68 to continued institutional care and 68 to project foster homes; 72 never-institutionalized children served as a comparison group.
  • Foster care produced significant gains over institutional care in most developmental domains, but foster children generally did not reach levels comparable to community-raised Romanian children, suggesting only partial recovery.
  • Timing mattered for some domains: placement before 24 months was associated with better brain activity and attachment outcomes than placement after 24 months; psychiatric symptom reduction did not differ by earlier versus later placement.
  • Ethical safeguards included local commissioner consent, university IRB approvals, caregiver assent, noninterference with placement decisions, and post-trial efforts to transfer foster homes to government support; at 54 months, the care-as-usual group included 28 still institutionalized, 9 adopted in Romania, 18 in government foster care, 11 returned to biological families, and 2 placed with extended family.

Methods

  • Randomized controlled trial conducted 2000–2005 in Bucharest, Romania, with ongoing follow-up; three U.S. principal investigators partnered with a Romanian NGO to assess children, create a foster care network, and employ study personnel.
  • Baseline assessments covered cognitive, language, social, and psychiatric measures; caregiver-child and examiner-child interactions; physical measurements; and brain electrical activity via EEG and event-related responses.
  • Analyses used an intent-to-treat strategy; the paper also discusses ethical design and implementation rather than presenting new primary outcome analyses.

Limitations

  • The paper states that foster children had many risk factors not shared by never-institutionalized children, which may have contributed to incomplete recovery.
  • The paper states that a stop rule could not be used because of foster care costs and funding limits; instead, early findings were shared through a press conference and professional meetings.
  • Evident from the text: this is an ethics case study/commentary, not a full outcome report, so effect sizes, confidence intervals, and detailed domain-specific results are not provided here; the paper also notes that cross-cultural cautions apply when generalizing BEIP results.

    The intent-to-treat analysis likely makes the estimated advantages of family care over institutional care conservative.

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.
