The pattern of correlations between the EssenCES scales and other climate-related variables support the construct validity of the EssenCES measure, with the exception of the Patient Cohesion subscale.Conclusions Although preliminary, these data suggest that the English version of EssenCES may be a valid tool for assessing the social climate of high secure hospital settings in the UK, but a larger research study is required, covering a wider range of psychiatric disorders, types of service and levels of security.

However, evidence about offender behaviour is not the only evidence available at a crime scene. This study extends previous collaborative research between forensic scientists and psychologists (e.g. Bond & Sheridan, Journal of Forensic Science, 52, 1122–1128, 2007) to investigate how forensic science can assist in the psychological process of offender profiling. Specifically, the potential utility of footwear impression evidence in the task of offender profiling is investigated. Using 155 domestic burglaries, the consistency and homology assumptions underlying offender profiling were tested. Evidence supportive of both assumptions is reported. A multiple regression analysis identified significant relationships between cost of footwear and employment status, age of offender, and the relative deprivation of his/her residence.

Data from 386 solved vehicle thefts committed by 193 offenders were analysed using Jaccard's, regression and Receiver Operating Characteristic analyses to determine whether objectively observable aspects of crime scene behaviour could be used to distinguish crimes committed by the same offender from those committed by different offenders. The findings indicate that spatial behaviour, specifically the distance between theft locations and between dump locations, is a highly consistent and distinctive aspect of vehicle theft behaviour; thus, intercrime and interdump distance represent the most useful aspects of vehicle theft for the purpose of case linkage analysis. The findings have theoretical and practical implications for understanding of criminal behaviour and for the development of decision-support tools to assist police investigation and apprehension of serial vehicle theft offenders.

Research paper thumbnail of A theoretical and practical test of geographical profiling with serial vehicle theft in a U.K. context

The validity of geographical profiling, however, has not been fully explored for certain crime types. This study, therefore, presents a preliminary test of the potential for geographical profiling with a sample of 145 serial vehicle thieves from the U.K. The behavioural assumptions underlying geographical profiling (distance decay and domocentricity) are tested and a simple practical test of profiling using the spatial mean is presented. There is evidence for distance decay but not domocentricity among the spatial behaviour of car thieves from the U.K. A degree of success was achieved when applying the spatial mean on a case-by-case basis. The level of success varied, however, and neither series length in days nor number of crimes could account for the variation. The findings question previously held assumptions regarding geographical profiling and have potential theoretical and practical implications for the study and investigation of vehicle theft in the U.K. Copyright © 2009 John Wiley & Sons, Ltd.
