The following statistics are the result of initial data collection and analysis conducted between March 2012 — August 2013.

The table below compares the rate of variables among inmates who screened positive for Attention Deficit Hyperactivity Disorder (i.e. reported symptoms highly consistent with ADHD in adults) and those who screened negative (i.e. the control group).
Many of these variables translate into risk factors for problematic encounters with the criminal justice system.

59% of participants screened positive for ADHD, compared to 26% screened negative. (14% of results were deemed inconclusive.) Only 58% of those screened positive for ADHD had ever been diagnosed. At the time, none were receiving treatment.
NB: Because participation in the survey and preliminary screening was offered to all interested inmates following an introductory presentation on AD/HD and our program, these statistics are not intended to represent incidence of AD/HD among a random sample pool, but rather represent patterns in relevant background information among informed participants.

Statistics are based on a survey of 160 male inmates.* The average age of participants was 31 years old.
