This summary is based on two linked studies of an innovative programme which took place between 2006 and 2009.
The first focused on the treatment delivered to and experienced by dangerous and severe personality disorder (DSPD) prisoners/patients. It was called IDEA (Inclusion for DSPD: Evaluating assessment and treatment).
The second study was concerned with management and staffing of the four high-secure DSPD units for men. It was called MEMOS (Management, organisation and staffing of DSPD).
