maltreatment & adversity outcomes

Childhood maltreatment causes lasting mental-health harm

Childhood maltreatment (abuse and neglect) is associated with substantially elevated lifelong risk of depression, anxiety, PTSD, substance use, and suicidality; quasi-experimental and genetically-informed designs indicate part of this association is causal, though smaller than raw associations because shared genetic and environmental factors also contribute.

maltreatment & adversity outcomes

Neglect alone can lastingly impair a child's development

Childhood neglect — the chronic absence of expected cognitive, linguistic, social, and caregiving input — is associated with substantial, often lasting deficits in cognitive ability, executive function, and brain development; the deprivation pathway is distinct from the threat pathway of abuse, and randomized evidence from early-deprivation studies supports a causal contribution.

maltreatment & adversity outcomes

Childhood sexual abuse causes broad, lasting harm to health

Childhood sexual abuse is associated with a broad, dose-responsive elevation in long-term psychiatric and physical-health risk — depression, anxiety, PTSD, suicidality, and substance dependence among them — and the strongest designs (umbrella reviews, longitudinal cohorts, discordant-twin studies) indicate the association is at least partly causal and not merely a product of shared family confounding; nonetheless many survivors show resilience and no measurable lasting impairment.

placement decisions

Family care beats institutional care for young children

For young children deprived of parental care, placement into stable, high-quality family (foster) care rather than institutional care produces lasting gains in cognitive ability, attachment security, and mental health; benefits are larger with earlier placement and greater placement stability, although some deficits persist.

permanency & family connections

Most adopted children develop within the normal range

Most adopted children develop within the normal range, but as a group adoptees show a modestly elevated risk of emotional, behavioral, and mental-health difficulties relative to non-adopted peers in intact biological families; risk rises with later age at placement and pre-adoption adversity, and adoption itself is a strongly beneficial intervention relative to remaining institutionalized.
