This retrospective study is based on the counseling registry of the Juvenile Affairs Division of Taipei City Police Department. The dataset encompasses around 1000 juvenile offenders who were actively followed up by the counselors of the division. The records include the offenders' sociodemographic data, medical history, and criminal history without person-identifiable data (i.e., name, ID).

Exclusion Criteria:
ADHD is among the most commonly diagnosed neurodevelopmental disorders, and the worldwide prevalence.
Other: collect data
Autistic spectrum disorder (ASD), characterized by overriding obsessions and difficulties in social cognition, might render the affected individuals vulnerable for becoming an offender or a victim of crime.
Other: collect data
Conduct disorder (CD), characterized by antisocial and aggressive behavior, affects 2-2.5% of children and adolescents. CD is a risk factor for antisocial personality disorder, and despite the fact that a CD diagnosis completely relies on behavioral symptoms, research has identified neurocognitive impairments.
Other: collect data
The Juvenile Affairs Division provided the records without person-identifiable data (i.e., name, ID) to the researchers. The researchers coded the above data (i.e., the offenders' sociodemographic data, medical history, and criminal history). Demographic characteristics were collected, which are the offenders' age, gender, occupation, education level, and residence (district). We recorded the offenders' household members (without the name or age), main caregivers (e.g., father, or mother), and the parents' socioeconomic and marital status. We also tracked whether the offenders live with family members with mental illness, whether they are from at-risk families, and whether had been victims of domestic violence. The medical history and deviant (or criminal) behaviors will be collected in the attached measure.
Prevalence of ADHD, ASD, and other neurodevelopmental disorder in juvenile offender
Statistical analysis done by SAS (v.9.4) examine the prevalence of each neurodelopmental disorder, such as ADHD and ASD.
Time frame: 3 years
Age of first criminal behavior
Based on different neurodevelopmental disorder diagnosis, determine whether the data is able to predict onset and type of criminal behaviors for each juvenile offender.
Time frame: 3 years
Plan to share: No — The collected data only stay in Dr.Chien's lab
