Undetected, Not Absent: preprint and code released

Adult-onset Arrest My Add Health paper, Undetected, Not Absent: Adolescent Substance Use, Unaddressed Behavior, and First Arrest in Adulthood, is no longer under review. I am posting it as a preprint on CrimRxiv so the findings are available now. The paper asks whether people first arrested as adults were new to offending, or whether their adolescent behavior simply went unnoticed. Most of those first arrested in adulthood reported offending or substance use as teenagers, and many of them never drew a response from school, a counselor, treatment, or the police.

The R code, a list of every correction made along the way, and the aggregate results of a full run are public on GitHub and archived at Zenodo (DOI: 10.5281/zenodo.22908607). The Add Health data themselves are not included; they are available from ICPSR. The preprint is now posted on CrimRxiv (DOI: 10.21428/cb6ab371.e9e0d613).
