What was done
Data from the Dunedin longitudinal study were used to evaluate childhood risk factors (including parenting, neurocognitive problems, temperament, and behavior issues) in males and females exhibiting childhood-onset versus adolescent-onset antisocial behavior.
What was found
Childhood-onset delinquents had high-risk backgrounds with inadequate parenting, neurocognitive problems, and temperament/behavior problems, whereas adolescent-onset delinquents lacked these early risk factors. The male-to-female ratio was 10:1 for childhood-onset delinquency and 1.5:1 for adolescence-onset delinquency. Childhood-onset females showed the same high-risk background pattern as males, whereas adolescent-onset females did not. Specific numerical effect sizes and statistical test values were not reported in the abstract.
Why it matters
This study provides empirical support for the taxonomic theory of antisocial behavior, demonstrating that distinct developmental pathways (life-course persistent vs. adolescence-limited) operate similarly across sexes but differ markedly in early risk etiology and sex ratios.
Limits
The abstract does not state the sample size (n), exact statistical metrics, or attrition rates. Findings from a single birth cohort may have geographic or demographic limits to generalizability, and the observational design cannot establish direct causal mechanisms for individual risk factors.
