The evaluation of HM Prison Service accredited Enhanced Thinking Skills (ETS) programme (The Treatment Chance Project—TCP) aims to examine the impact of ETS courses on impulsivity in adult male offenders over the age of 18, and to investigate whether changes in levels of impulsivity were reflected in changes in prison behaviour.
The TCP was conducted as a Randomised Control Trial (RCT), and as such is the first large-scale RCT evaluating the impact of ETS in prisons.
The draft report is at the peer review stage, with publication scheduled for April 2008.
