In addition, RST-related psychometric measures were used. Both experimental and psychometric data were of interest to determine whether sex offenders could be reliably differentiated from non-offenders. Paraphilic (N=50) and impulse control-disordered (N=48) sex offenders showed greater sensitivity to continuous reward than male non-offenders (N=51). Impulse control-disordered sex offenders showed less behavioural adaptation under non-reward than both paraphilic sex offenders and male non-offenders. In addition, reward sensitivity, rash-spontaneous impulsivity, and anxiety measures discriminated sex offenders from male non-offenders. The results suggest that reinforcement sensitivity is a promising personality trait for differentiating subgroups of sex offenders from non-offenders. The experimental and psychometric results illustrate that predictive accuracy in forensic settings could be improved by combining several types of data.", pages = "361-378(18)", url = "http://www.ingentaconnect.com/content/bpsoc/bjp/2008/00000099/00000003/art00006" doi = "doi:10.1348/000712607X228519" }
