Tew, J., Dixon, L., Harkins, L., & Bennett, A. (2012). Investigating changes in anger and aggression in offenders with high levels of psychopathic traits attending the Chromis violence reduction programme. Criminal behaviour and mental health, 22(3), 191-201.
Background: Chromis was accredited by the Correction Services Accreditation Panel in 2005 as an intervention designed to reduce violence in offenders whose level or combination of psychopathic traits disrupts their ability to engage in treatment and change. It runs as part of the regime in the dangerous and severe personality disorder unit in HM Prison Frankland (Westgate). A multiple case study investigation into changes over time in participants is currently underway, part of which is reported here. Aims: This paper reports on information relating to changes in anger and aggression in Chromis completers. Methods: Change in psychometrics and observed incidents of verbal and physical aggression are considered for five case study participants who have completed Chromis and progressed from Westgate to a different location. Results: Findings suggest that cases experienced a reduction in self-reported anger, and expected incidents of physical aggression but had higher than expected levels of verbal aggression after leaving Westgate. Conclusions: These findings offer cautious optimism for the effectiveness of Chromis, although methodological limitations must also be considered. Findings may be seen as positive indicators of Chromis, or at least the approach to working with these offenders across Westgate, in reducing violence. Implications for practice: Findings support the continued delivery and evaluation of Chromis. There may be benefit in exploring ways to further understand and address verbal aggression in participants. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
