out-of-home care / placement stability

Among children in out-of-home care, placement instability (frequent placement changes) is associated with worse behavioral and mental-health outcomes — especially externalizing problems and PTSD symptoms — and propensity-adjusted work indicates an effect of instability beyond children's baseline problems; the relationship is partly bidirectional, since behavioral difficulties also drive disruptions.

For the Court

Established that placement instability is associated with worse behavioral and mental-health outcomes; the acknowledged nuance is partial bidirectionality and confounding by prior adversity.

What This Claim Does NOT Say

Does not establish purely one-directional causation; the relationship is bidirectional — behavioral and mental-health difficulties also precipitate placement changes.
Does not claim every disruption harms; some studies find instability not necessarily damaging over shorter horizons.
Does not attribute outcomes to instability alone; pre-placement maltreatment and baseline problems are major confounders.
Does not establish a specific threshold number of placements above which harm occurs; measurement of instability is inconsistent across studies.

Scope — Where It Holds

Drawn from large administrative and longitudinal cohorts (NSCAW, propensity-adjusted) and two meta-analyses (Konijn 2019, r≈0.35 for behavior problems; UK 2025, OR 2.07). Effects are modest-to-medium and generalize across countries, but causality is partly bidirectional and confounded by pre-placement maltreatment and baseline problems.

Observational
After adjusting for baseline attributes, instability independently predicted behavior problems — 36% among unstable vs 22% among early-stabilized low-risk children.

Meta-analysis
Child behavioral problems showed a medium association with placement instability (r = 0.35); effects generalized across continents and time.

Limits & Counter-considerations

Causation is partly bidirectional; effects are modest-to-medium and confounded by pre-placement maltreatment and baseline problems; instability is measured inconsistently across studies; and some studies find short-horizon instability not necessarily damaging.
