Childhood harm leaves marks. But many still did better than expected.

Cohort study. 2,066 people. cohort of 2,232 twins born 1994-1995, assessed at ages 5, 7, 10, 12 and 18 (93% retained at 18).

People were watched for years. Nobody was told what to do. A clue, not proof.

Who: Nationally representative twins born in England and Wales in 1994-1995 (90.4% White); 2,066 assessed at 18, of whom 558 (27%) had faced severe victimization between birth and age 12

More to know, from our read of the paper:

• Observational cohort: linked, not proven. Adjusted for sex, age-5 IQ, family SES and family psychiatric history only
• 'Flourishing' is relative: a victimized child counts as flourishing on a measure when their actual score at 18 is above the score PREDICTED from victimization + covariates (residual > 0). Within the victimized group roughly half sit above prediction by construction, so the 34-63% per-measure rates mostly reflect the definition. Say 'did better than predicted/expected for their background', never 'thrived' in an absolute sense and never compare the 63% to a norm
• The 39% figure = flourishing on at least one measure in EACH of the four domains (social, education/cognition, physical health, mental well-being); mental well-being = life satisfaction only
• Polyvictimization and type-of-victimization results are odds ratios from binary logistic regression among the 558 only; show as 'lower odds', no percentages. Many comparisons tested, few significant, p-values near .02-.04
• Twins only, mostly White, UK, single time point at 18; no standard flourishing definition (authors' own limitation)

Researchers followed 2,232 twins born in England and Wales in 1994-1995 to age 18. By age 12, 558 of the 2,066 seen at 18 had faced severe abuse, neglect, bullying or violence at home. On average, they did worse at 18 on most measures, like sleep quality and life satisfaction. Still, 39% did better than predicted for their background on at least one measure in each of four areas of life. It is an observational study: linked, not proven.
