BACKGROUND The social climate of forensic units is important but little investigated, in part because of the unavailability of a clinically practical and statistically sound measure. AIMS To provide preliminary psychometric and normative data for the English version of the Essen Climate Evaluation Schema (EssenCES) in UK high-security hospital settings. METHOD A total of 324 staff and patients from three high-security hospital services completed the EssenCES, and a subgroup completed a range of other questionnaires related to therapeutic milieu and working environment (GMI, WAAM, WES-10). RESULTS The original three-factor structure and satisfactory internal consistency were retained. 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.

In the absence of forensic evidence (such as DNA or fingerprints), offender behavior can be used to identify crimes that have been committed by the same person (referred to as behavioral case linkage). The current study presents the first empirical test of whether it is possible to link different types of crime using simple aspects of offender behavior. The discrimination accuracy of the kilometer distance between offense locations (the intercrime distance) and the number of days between offenses (temporal proximity) was examined across a range of crimes, including violent, sexual, and property-related offenses. Both the intercrime distance and temporal proximity were able to achieve statistically significant levels of discrimination accuracy that were comparable across and within crime types and categories. The theoretical and practical implications of these findings are discussed and recommendations made for future research.

The social climate of correctional (forensic) settings is likely to have a significant impact on the outcome of treatment and the overall functioning of these units. The Essen Climate Evaluation Schema (EssenCES) provides an objective way of measuring social climate that overcomes the content, length, and psychometric limitations of other measures. But the English translation of the EssenCES has yet to be sufficiently validated for use in forensic settings in the United Kingdom. The current study presents psychometric properties (factor structure and internal consistency) and an examination of construct validity with the English EssenCES. Satisfactory internal consistency was found for all EssenCES scales, and the expected three-factor structure was confirmed with both staff and residents and in prison and secure hospital settings using confirmatory factor analysis. Evidence to support construct validity was established using multilevel models, which showed statistically significant associations between scores on the EssenCES and scores on the Working Environment Scale, institutional aggression, and site security. Future validation work and potential practical applications of the EssenCES are discussed.

Behavioural case linkage with solved and unsolved crimes

Matthew Tonkin; Jessica Woodhams; Ray Bull; John W. Bond

Offender behaviour is used to distinguish between crimes committed by the same person (linked crimes) and crimes committed by different people (unlinked crimes) through behavioural case linkage. There is growing evidence to support the use of behavioural case linkage by investigative organisations such as the police, but this research is typically limited to samples of solved crime that do not reflect how this procedure is used in real life. The current paper extends previous research by testing the potential for behavioural case linkage in a sample containing both solved and unsolved crimes. Discrimination accuracy is examined across crime categories (e.g. a crime pair containing a car theft and a residential burglary), across crime types (e.g. a crime pair containing a residential burglary and a commercial burglary), and within crime types (e.g. a crime pair containing two residential burglaries) using the number of kilometres (intercrime distance) and the number of days (temporal proximity) between offences to distinguish between linked and unlinked crimes. The intercrime distance and/or the temporal proximity were able to achieve statistically significant levels of discrimination accuracy across crime categories, across crime types, and within crime types as measured by Receiver Operating Characteristic (ROC) analysis. This suggests that behavioural case linkage can be used to assist the investigation, detection and prosecution of prolific and versatile serial offenders.

A Review of Questionnaire Measures for Assessing the Social Climate in Prisons and Forensic Psychiatric Hospitals

Matthew Tonkin

Significant time and resources are devoted to the monitoring of social climate in secure settings. However, if these efforts are to help (rather than hinder) attempts to improve the functioning of such units, the monitoring of social climate must be based on sound psychometric methods. The aim of this review was to determine what questionnaires exist to measure the social climate in secure settings and what evidence exists regarding their psychometric properties. Twelve questionnaire-based measures of social climate were identified. The Essen Climate Evaluation Schema has received the most consistent empirical support, but this questionnaire does not provide as much of an in-depth, detailed insight into social climate as that provided by other social climate questionnaires. Although more extensive measures of climate exist, they have not yet received sufficient validation to justify their routine use in practice. Nevertheless, there is growing evidence that some questionnaire-based measures can provide a reliable and valid assessment of the social climate in secure settings, which has important clinical and theoretical implications.

The impact of interpersonal style and perceived coercion on aggression and self-harm in personality-disordered patients admitted to a secure psychiatric hospital

Recent research on aggressive behaviour in psychiatric hospitals has emphasised the importance of the interaction between characteristics of patients and the hospital environment. Interpersonal style, a key component of personality and personality disorder, has emerged as a potentially important characteristic that may be relevant to a patients interactions with the hospital environment. Interpersonal style affects how patients relate to others and how they respond to the demands of treatment. This study explored the impact of interpersonal style and perceptions of staff coercion on aggression and self-harm. Participants were 39 patients with personality disorder admitted involuntarily to a secure psychiatric hospital. Results showed that perceptions of coercion were high but unrelated to aggression and self-harm. Interpersonal style did not relate to perceived coercion. However, patients with a more coercive interpersonal style, as measured by the Chart of Interpersonal Reactions in Closed Living Environments, were more likely to self-harm and/or act aggressively. Possible implications for the treatment of aggressive individuals and the prevention of aggressive behaviour are made.

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

Matthew Tonkin; Jessica Woodhams; John W. Bond; Trudy Loe

Geographical profiling is an investigative methodology sometimes employed by the police to predict the residence of an unknown offender from the locations of his/her crimes. 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.

Workability and mental wellbeing among therapeutic prison officers

E. J. Walker; Craig Jackson; Helen Egan; Matthew Tonkin

BACKGROUND Previous research has examined how age and health can shape workability (WA). This study seeks to explore how a lack of WA (inability) may affect the health of the employee. AIMS To explore the effects of work inability on mental wellbeing among therapeutic prison officers. METHODS An anonymous cross-sectional study of prison officers conducted in a category B English prison using the Work Ability Index (WAI) and General Health Questionnaire-28 (GHQ). RESULTS Fifty-seven officers (59%) participated and of those 95% achieved GHQ caseness. Officers with poorer WA reported significantly higher GHQ scores. Work inability for mental demands had significant associations with anxiety (β = -0.58, 95% CI -4.21 to -1.88, particularly sleep loss; Pearsons r = -0.66). CONCLUSIONS Our findings present clear associations between poor WA and its impact upon mental wellbeing. The results of this study may help to focus on areas for intervention such as improving WA and promoting mental wellbeing.

Treatment Engagement From the Perspective of the Offender Reasons for Noncompletion and Completion of Treatment—A Systematic Review

Danielle Sturgess; Jessica Woodhams; Matthew Tonkin

A systematic review of the reasons why detained adult offenders fail to attend or successfully complete treatment programme(s) was conducted. An initial search of the literature identified 2,827 articles, which following evaluation against explicit inclusion/exclusion criteria and a quality assessment was reduced to 13 studies. Extracted data from the 13 studies were synthesised using a qualitative approach. Despite the 13 studies being heterogeneous in design, there was consensus on the reasons offenders gave for completion/noncompletion of treatment. The majority were consistent with the factors outlined in the Multifactor Offender Readiness Model (MORM) and included a perceived lack of self-efficacy, negative perceptions of treatment, staff and peers, an inability to regulate emotions, and a lack of perceived choice and control. A lack of opportunity to engage in established, professionally run, groups, as well as perceived inadequate support from members of staff, was also associated with poor engagement and noncompletion of treatment.

The Essen Climate Evaluation Schema EssenCES: A Manual and More

Matthew Tonkin; Andrew Day; Sharon Casey; Norbert Schalast

Designed as a quick and easy tool to help assess the essential traits of the social and therapeutic atmosphere in forensic psychiatric settings (subsequently expanded for use in correctional facilities), the Essen Climate Evaluation Schema (EssenCES) was originally developed and first published in Germany. It has since been translated into a number of other languages and been included in a considerable number of studies, among them a broad validation study in the UK. Following this study andthe UK Commissioning for Quality and Innovation (CQUIN) initiating the regular use of the scale in forensic psychiatric services in the UK, we have received a large number of enquiries regarding support in using the scale and interpreting its findings. In particular, many researchers and clinicians have requested reference norms that would allow them to compare the EssenCES scores obtained in their particular unit/service with the scores obtained in other settings. This manual aims to respond to these enquiries. It outlines the background and the concept of the instrument and discusses the variety of ways in which the EssenCES might be used to support research and practice within forensic services.It also includes considerations regarding the limitations of previous studies that have utilised the concept of social climate and a discussion of how the contribution of climate evaluations might be further improved in the future.
