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.

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.

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.

Parental substance use raises risk but does not prove unfitness

Parental substance use disorder is a moderate risk factor for child maltreatment and for worse developmental, behavioral, and mental-health outcomes, operating largely through impaired, inconsistent, or disengaged caregiving; the risk is graded by severity of use and substance type, is confounded by co-occurring adversity, and substance use alone does not establish maltreatment or parental unfitness.

Parental incarceration harms children — less than raw numbers suggest

Parental incarceration is associated with worse child outcomes — particularly antisocial behavior and, into young adulthood, anxiety, substance-use disorder, and reduced educational attainment — but the most rigorous studies, which control for pre-existing antisocial behavior and shared genetic/family confounding, find the independent effect is smaller and uneven across domains; paternal-incarceration effects are better supported than maternal, and much of the raw association reflects selection.
