Study summary

The purpose of this study is to determine the long term effects of early intervention (placement into foster care) on physical, cognitive, social and brain development and psychiatric symptomatology in previously institutionalized children.

Read the detailed description

The Bucharest Early Intervention Project (BEIP) was a randomized controlled trial of foster care as an intervention for children abandoned at or around the time of birth and placed in one of six institutions for young children in Bucharest, Romania (Zeanah et al., 2003). The PI (Nelson) and Co-PIs (Zeanah and Fox) conducted this study beginning in the fall of 2000 from baseline assessments and implementation of the intervention in the spring of 2001.

The BEIP began with comprehensive assessments of 136 institutionalized children and their caregiving environments prior to randomization. Half the children were randomly assigned to high-quality foster care and the other half to remain in institutional care. The average age at foster care placement was 22 months (range=6-31 months). All children were initially seen prior to randomization and again for follow-up assessments at 30 months, 42 months 54 months, 8 years, 12 year and 16 years of age. The development of children in foster care was compared to the development of children in institutions and to a group of never institutionalized children (community controls). These children, now young adults are being assessed at age 21 years.

Study arms

  • Experimental
    Foster Care Placement Group

    Children randomized to this group were placed in high quality foster care developed for the study.

    Other: Foster Care Placement

  • No intervention
    Care As Usual Group

    Children randomized to this group remained in institutional care.

Interventions

  • OtherFoster Care Placement

    A group of children living in institutions in Bucharest, Romania was randomly assigned to placement in foster care. Foster parents were recruited, consented to background checks, and trained in Romanian. Before placement, foster parents visited their children to begin developing a relationship with the child. Hired foster parents were supported and monitored by project social workers. Foster parents in the BEIP network received frequent visits from the social workers, with visits occurring weekly for several months after placement of the child, then biweekly and later monthly. Foster parents were invited to participate in a support group organized by social workers. Project social workers consulted weekly with US staff experienced in dealing with young children in foster care.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2000 (actual). Primary completion is estimated for Mar 2027, 318 months after the start.

Of 567 non-industry interventional studies with no phase under Health Behavior, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 33. This study's planned 318 months is above that.

Counting every sponsor, half of 585 studies reached it within 15 months; a quarter within 5 and three quarters within 32.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
