Measuring risk and related behaviour with the Behavioural Status Index (BSI): some preliminary psychometric studies.

British Special Hospitals are key caregivers for mentally disordered individuals who may display extreme anti-social and challenging behaviour. Assessment of risk and related diurnal behaviour is central to treatment planning for these patients. This paper describes a behaviourally based assessment instrument to assist in the process of the assessment of these 'risky' and related diurnal behaviour. Results of some early data analysis are reported.
