Question 23

Different roles of a forensic psychologist

Answer 23

Forensic psychologists often have specific and different areas of expertise, since the knowledge base of forensic psychologists cuts across clinical, educational, social, developmental, abnormal, neurophysiological, occupational and other areas of psychology.
(Craig, Dixon, & Gannon, 2013; Gudjonsson, Sigurdsson, Sigurdardottir, Steinthorsson, & Sigurdardottir, 2014; Wilcox, 2013).

In addition, the forensic psychologist’s recognised area of expertise may centre around assessment (Craig & Rettenberger, 2016), treatment (Wilcox, Garrett, & Harkins, 2014), theory (Ward & Beech, 2016) or research (Davies & Valentine, 2007). However, longer term involvement in expert reporting tends to give rise to a gradual development and diversification of professional interests and an expansion of the expert’s skill base.
