The Computations of hostile biases (CHB) model: Grounding hostility biases in a unified cognitive framework.

Our behavior is partly a product of our perception of the world, and aggressive individuals have been found to have 'hostility biases' in their perception and interpretation of social information. Four types of hostility biases can be distinguished: the hostile attribution, interpretation, expectation, and perception bias. Such low-level biases are believed to have a profound influence on decision-making, and possibly also increase the likelihood of engaging in aggressive acts.

Psychometric properties of the forensic inpatient quality of life questionnaire: quality of life assessment for long-term forensic psychiatric care.

A substantial group of forensic psychiatric patients require (life)long forensic psychiatric care. Instead of aiming at re-entry into society, treatment in long-term forensic psychiatric care (LFPC) is principally aimed at medical and psychiatric care and optimising quality of life (QoL). To assess QoL in LFPC, the influence of both the mental disorder and the restrictive context should be considered.

Assessing aggressive behavior in forensic psychiatric patients: validity and clinical utility of combining two instruments.

Objectives: Accurate observation of aggressive behavior among forensic psychiatric patients requires valid instruments. This study examines the validity and clinical utility of combining the social dysfunction and aggression scale (SDAS) and staff observation aggression scale revised (SOAS-R).

Methods: Nurses weekly obtained SDAS scores of 127 patients, resulting in 6.
