Parsing Heterogeneity: Sex Differences in Youth Antisocial Behavior.
Level 3 - non-randomized controlled study
Cross-sectional latent profile analysis of a large observational cohort
PubMed 41879049 · doi:10.1002/ab.70065
What was done
Latent profile analyses were conducted separately by sex in a nationally representative sample of 7,655 youth from the Adolescent Brain and Cognitive Development (ABCD) Study. Profiling used four behavioral indicators: physical aggression, relational aggression, callous-unemotional (CU) traits, and conduct symptom severity. Profiles were also compared on overall distress.
What was found
The abstract does not report specific numerical values, percentages, or effect sizes. Qualitatively, profiles in females were primarily distinguished by varying levels of CU traits, whereas male profiles were primarily differentiated by physical aggression. Both sexes demonstrated distinct higher-risk profiles (elevated aggression and/or CU traits) and lower-severity profiles (minimal conduct problems and aggression). Overall distress differed significantly across profiles, with the highest distress in higher-risk males and the lowest in lower-risk females.
Why it matters
Demonstrates that antisocial behavior phenotyping differs fundamentally between boys and girls, suggesting that assessment and intervention should account for sex-specific patterns rather than assuming uniform symptom presentations.
Limits
The abstract provides no exact quantitative metrics (such as profile sizes, model fit statistics, or effect sizes). The cross-sectional profile analysis does not establish developmental trajectories or causal mechanisms, and findings are reliant on the specific measures captured within the ABCD dataset.
