The present study examined whether adults with high functioning autism (HFA) showed greater difficulties in (1) their self-reported ability to empathise with others and/or (2) their ability to read mental states in others' eyes than adults with Asperger syndrome (AS). The Empathy Quotient (EQ) and 'Reading the Mind in the Eyes' Test (Eyes Test) were(More)
BACKGROUND The social climate of inpatient facilities is thought to be an important contributor to treatment outcome. However, little research has focused on this construct within secure forensic services for people with intellectual disabilities (ID). Therefore, the objective of this study was to investigate the social climate of two different types of(More)

DESIGN Using a cross-sectional related-samples design, EE and attributions were measured amongst all staff working with one client with(More)

In order to address this short-coming, a moral reasoning production measure (the Socio-Moral Reflection Measure--Short Form; SRM-SF) and a recognition measure(More)

Offenders categorised as(More)

Nevertheless, as service users, they can be consulted and involved in a variety of different ways, including ascertaining their views of the services they receive. METHOD A group of 16 men with ID and sexually abusive behaviour were(More)

It was hypothesized that there would be relationships (1) between staff exposure to challenging(More)
