Racialised staff-patient relationships in inpatient mental health wards: a realist secondary qualitative analysis of patient experience data.

BACKGROUND: The current study is a secondary analysis of qualitative data collected as part of EURIPIDES, a study which assessed how patient experience data were used to improve the quality of care in National Health Service (NHS) mental health services. OBJECTIVE: We undertook a detailed realist secondary qualitative analysis of 10 interviews in which expressions of racialisation were unexpectedly reported. This theme and these data did not form part of the primary realist evaluation. METHODS: Interviews were originally conducted with the patients (18-65 years: 40% female, 60% male) from four different geographically located NHS England mental health trusts between July and October 2017. Secondary qualitative data analysis was conducted in two phases: (1) reflexive thematic analysis and retroduction; (2) refinement of context-mechanism-outcome configurations to explore the generative mechanisms underpinning processes of racialisation and revision of the initial programme theory. FINDINGS: There were two main themes: (1) absence of safe spaces to discuss racialisation which silenced and isolated patients; (2) strained communication and power imbalances shaped a process of mutual racialisation by patients and staff. Non-reporting of racialisation and discrimination elicited emotions such as feeling othered, misunderstood, disempowered and fearful. CONCLUSIONS: The culture of silence, non-reporting and power imbalances in inpatient wards perpetuated relational racialisation and prevented authentic feedback and staff-patient rapport. CLINICAL IMPLICATIONS: Racialisation in mental health trusts reflects lack of psychological safety which weakens staff-patient rapport and has implications for authentic patient engagement in feedback and quality improvement processes. Larger-scale studies are needed to investigate racialisation in the staff-patient relationships.

Using Structural Equation Modelling in Routine Clinical Data on Diabetes and Depression: Observational Cohort Study.

BACKGROUND: Large data sets comprising routine clinical data are becoming increasingly available for use in health research. These data sets contain many clinical variables that might not lend themselves to use in research. Structural equation modelling (SEM) is a statistical technique that might allow for the creation of "research-friendly" clinical constructs from these routine clinical variables and therefore could be an appropriate analytic method to apply more widely to routine clinical data. OBJECTIVE: SEM was applied to a large data set of routine clinical data developed in East London to model well-established clinical associations. Depression is common among patients with type 2 diabetes, and is associated with poor diabetic control, increased diabetic complications, increased health service utilization, and increased health care costs. Evidence from trial data suggests that integrating psychological treatment into diabetes care can improve health status and reduce costs. Attempting to model these known associations using SEM will test the utility of this technique in routine clinical data sets. METHODS: Data were cleaned extensively prior to analysis. SEM was used to investigate associations between depression, diabetic control, diabetic care, mental health treatment, and Accident & Emergency (A&E) use in patients with type 2 diabetes. The creation of the latent variables and the direction of association between latent variables in the model was based upon established clinical knowledge. RESULTS: The results provided partial support for the application of SEM to routine clinical data. Overall, 19% (3106/16,353) of patients with type 2 diabetes had received a diagnosis of depression. In line with known clinical associations, depression was associated with worse diabetic control (ß=.034, P<.001) and increased A&E use (ß=.071, P<.001). However, contrary to expectation, worse diabetic control was associated with lower A&E use (ß=-.055, P<.001) and receipt of mental health treatment did not impact upon diabetic control (P=.39). Receipt of diabetes care was associated with better diabetic control (ß=-.072, P<.001), having depression (ß=.018, P=.007), and receiving mental health treatment (ß=.046, P<.001), which might suggest that comprehensive integrated care packages are being delivered in East London. CONCLUSIONS: Some established clinical associations were successfully modelled in a sample of patients with type 2 diabetes in a way that made clinical sense, providing partial evidence for the utility of SEM in routine clinical data. Several issues relating to data quality emerged. Data improvement would have likely enhanced the utility of SEM in this data set.

Factors associated with successful reintegration for male offenders: a systematic narrative review with implicit causal model.

Objectives: This systematic review explored factors associated with successful reintegration into the community for male offenders and investigated which factors may be causally related to reintegration. Methods: Database searches were conducted in November 2021; a narrative synthesis and associated causal model with directed acyclic graph (DAG) was used to analyse the factors of reintegration. Results: Thirty-four studies met the inclusion criteria. Risk-Need-Responsivity-based interventions had the strongest evidence for reducing post-release offending. Fourteen good-quality studies met the inclusion criteria. The DAG shows six exposure variables (prison visits, witnessing victimisation, recovery perception, risk assessment, in-prison treatment, and pre-prison health) which link to several post-release outcomes (criminal justice outcomes, drug use, mental health, housing, and reintegration barriers) and confounding variables (demographics, offending history, prior reintegration barriers, substance misuse and attitudes). Conclusions: The review identified factors that may be causally related to reintegration for male offenders and warrant further empirical investigation.

Offenders With Personality Disorder Who Fail to Progress: A Case-Control Study Using Partial Least Squares Structural Equation Modeling Path Analysis.

BACKGROUND: Offenders with personality disorder can be challenging to engage and retain in treatment. The UK Offender Personality Disorder (OPD) pathway aims to proactively and responsively identify and engage offenders with personality disorder. However, a subpopulation of offenders on the pathway have been found to not be accepted into any OPD service and therefore fail to progress. OBJECTIVE: This study aims to identify and describe offenders on the OPD pathway who fail to progress and to understand the causal drivers by which individuals fail to progress in the pathway. METHODS: A sample of 50 offenders on the OPD pathway who had been refused from at least two OPD services (nonprogression group) were compared to 100 offenders accepted into OPD services (control group). Partial least squares structural equation modeling was used to model the causal factors involved in not being accepted into OPD services. RESULTS: The path coefficients in the structural model showed that the most influential factor in nonprogression was attitude toward treatment (ß=.41; P<.001; f2=0.25) alongside those with psychopathology (ß=.41; P<.001; f2=0.25), specifically, psychopathy, psychosis, and co-occurring personality disorder. CONCLUSIONS: The findings of the study provide a basis of how to work with this population in the future to increase the likelihood of acceptance into OPD services.

Cohort profile: he East London Health and Care Partnership Data Repository: using novel integrated data to support commissioning and research.

PURPOSE: The East London Health and Care Partnership (ELHCP) Data Repository was established to support commissioning decisions in London. This dataset comprises routine clinical data for the general practitioner (GP)-registered populations of two London boroughs, Tower Hamlets and City and Hackney, and provides a rich source of demographic, clinical and health service use data of relevance to clinicians, commissioners, researchers and policy makers. This paper describes the dataset in its current form, its representativeness and data completeness. PARTICIPANTS: There were 351 749 and 344 511 members of the GP-registered population in the two boroughs, respectively, for the financial year 2017/2018. Demographic information and prevalence data were available for 9 mental health and 15 physical health conditions. Prevalence rates from the cohort were compared with local and national data. In order to illustrate the health service use data available in the dataset, emergency department use across mental health conditions was described. Information about data completeness was provided. FINDINGS TO DATE: The ELHCP Data Repository provides a rich source of information about a relatively young, urban, ethnically diverse, population within areas of socioeconomic deprivation. Prevalence data were in line with local and national statistics with some exceptions. Physical health conditions were more common in those with mental health conditions, reflecting that comorbidities are the norm rather than the exception. This has implications for integrated care. Data completeness for risk factors (eg, blood pressure, cholesterol) was high in patients with long-term conditions. FUTURE PLANS: The data are being further cleaned and evaluated using imputation, Bayesian and economic methods, principally focusing on specific cohorts, including type II diabetes, depression and personality disorder. Data continue to be collected for the foreseeable future to support commissioning decisions, which will also enable more long-term prospective analysis as data become available at the end of each financial year.

Assessing risks of violent extremism in depressive disorders: Developing and validating a new measure of Sympathies for Violent Protest and Terrorism.

OBJECTIVE: Clinicians are tasked with assessing the relationship between violence and mental illness. Yet, there is now a legal expectation in some countries that public services, including health professionals, assess risk of violent extremism - with few available measures. We previously developed a new measure of Sympathies for Radicalisation, using items that measure Sympathies for Violent Protest and Terrorism. In this paper, we present the detailed psychometric properties of a reduced item measure of Sympathies for Violent Protest and Terrorism. We use data from two studies to test replication and then validity against outcomes of self-reported violence and convictions in the entire sample and in those with depressive symptoms. METHODS: Data from two cross-sectional neighbourhood surveys, consisting of Pakistani and Bangladeshi adults (survey 1, n = 608) and White British and Pakistani adults (survey 2, n = 618), were used to undertake confirmatory factor analysis of Sympathies for Radicalisation and produce a short measure of Sympathies for Violent Protest and Terrorism. Survey 2 data were used to test the Sympathies for Violent Protest and Terrorism's convergent validity to classify presence/absence of violence and convictions in the whole sample and for subgroups by depressive disorder. RESULTS: The seven-item measure's structure was a consistent measure of extremist attitudes across the two surveys. A threshold score of zero to classify violence was optimal (specificity = 89.7%; area under the curve = 0.75), but sensitivity to a risk of violence was poor (34.5%). The short version Sympathies for Radicalisation was a better classifier of violence in respondents with depression, dysthymia or both (area under the curve = 0.78) than respondents with neither (area under the curve = 0.69; ß = 0.62, 95% confidence interval = [-0.67, 1.92]; standard error = 0.66). CONCLUSION: The seven-item measure of Sympathies for Violent Protest and Terrorism is an accessible and valid measure for clinical assessments and helpfully identifies low risk of violence. It enables clinicians to conduct detailed assessments of people endorsing one or more of the items, although further research is needed.

Agreement over content of case formulation in offender personality disorder pathway prison services.

BACKGROUND: Case formulation plays a key role in effective management of offenders' needs, particularly on the Offender Personality Disorder Pathway (OPDP). AIMS: To validate a method of investigating formulations with offenders still in prison but in the OPD Pathway and investigate agreement over the content of formulations between each of the main dyadic pairs: offender-clinician, offender-key worker and clinician-key worker. METHODS: We developed a checklist of the main features of a formulation from a review of initial formulations in the files of prisoners in two prisons which operate within the OPD Pathway system. We then recruited 30 violent offenders in each OPD wing of two prisons, and asked each of them, their clinically qualified worker (usually a psychologist) and the criminal justice system key worker to complete a formulation summary according to a card-sort process based on this checklist. We calculated the level of agreement between pairs of raters (e.g. offender and key worker) about the importance of aspects of each domain to the case using intraclass correlation coefficients. RESULTS: The rating tool showed good internal validity. Analysis of inter-rater ratings showed agreement among teams on aspects relating to prisoners' observable actions, experiences and external support domains, but little agreement on cognitions, feelings, risky situations or staff/self-support, mainly affecting the prisoner-key worker dyad. There were, however, significant differences in agreement rates between the two sites. CONCLUSIONS: Agreement within teams about formulations is strong where content relates to overt behaviours and points of fact, but weaker on risk, cognitions and support. The appropriateness of this approach to formulation across cultural groups may need further evaluation as the main measured difference between the prisons was in distribution of ethnic and cultural groups.

Indefinite detention or supervision for public protection when a life sentence is not available: Pathway outcomes among prisoners in one region.

BACKGROUND: Indeterminate sentences for Public Protection (IPPs) were introduced in England and Wales under the Criminal Justice Act 2003 for offenders not eligible for a life sentence but considered to pose a serious risk to the public. In 2012, new IPPs became illegal, in part after the European Court of Human Rights ruled in three cases that failure to make appropriate provision for rehabilitation services while the men were in prison breached their rights under Article 5 of the Convention and thus from arbitrary detention. People already sentenced under this provision, however, remained in the system. Humberside Indeterminate Public Protection Project (HIPPP) supports intensive case management of male IPP offenders still serving this sentence. AIMS: To examine variables associated with pathway outcome among men under IPPs in one English region-Humberside. Our primary hypothesis was that programme engagement in prison would be significantly associated with release. METHODS: The HM Prison and Probation Services National Delius (nDelius) and Offender Assessment System (OASys) were used to identify all men from the region subject to IPPs and beyond tariff (the fixed, punishment part of their sentence) and to retrieve data on the sentence, pathway status and specific risk factors. We used content analysis to identify variables of interest, and logistic regression models to explore associations of variables with different types of pathway outcome. RESULTS: A total of 82 men were identified, 34 of whom had ever been recorded as having been given a diagnosis of anti-social personality disorder (ASPD). Men experiencing relationship difficulties with professionals were significantly more likely to be denied release [Odds Ratio (OR) = 7.75, Confidence Interval (CI) 2.08-28.57], have a deferred parole (OR = 7.81, CI 1.59-38.46) or be awaiting parole (OR = 4.46, CI 1.09-18.18) compared with men released to the community or serving in an open prison. Completion of programmes was not associated with pathway outcome. A modest association between diagnosis of anti-social personality disorder and pathway outcome association was confounded by other variables. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: While programme completion did not have the expected association with release, relational difficulties with professionals proved significant barriers to release. This suggests that ambitions for the Offender Personality Disorder (OPD) pathway in supporting professionals to develop collaborative relationships with offenders are well founded. Part of this approach lies in sophisticated, psychologically informed case formulations which may help to discriminate between risk factors and personality disorder traits which have social rather than risk implications.

On the uses and abuses of narcissism as a public health issue.

Psychiatry understands narcissism as a pathological condition associated with poor social outcomes and difficulty relating to others. Millennials have been depicted by psychological research as 'narcissistic', and the term has lost accurate meaning. We underline the intellectual laxity of conflating social changes with narcissism and suggest ways forward.

Extremism and common mental illness: cross-sectional community survey of White British and Pakistani men and women living in England.

BACKGROUND: Mental illnesses may explain vulnerability to develop extremist beliefs that can lead to violent protest and terrorism. Yet there is little evidence. AIMS: To investigate the relationship between mental illnesses and extremist beliefs. METHOD: Population survey of 618 White British and Pakistani people in England. Extremism was assessed by an established measure of sympathies for violent protest and terrorism (SVPT). Respondents with any positive scores (showing sympathies) were compared with those with all negative scores. We calculated associations between extremist sympathies and ICD-10 diagnoses of depression and dysthymia, and symptoms of anxiety, personality difficulties, autism and post-traumatic stress. Also considered were demographics, life events, social assets, political engagement and criminal convictions. RESULTS: SVPT were more common in those with major depression with dysthymia (risk ratio 4.07, 95% CI 1.37-12.05, P = 0.01), symptoms of anxiety (risk ratio 1.09, 95% CI 1.03-1.15, P = 0.002) or post-traumatic stress (risk ratio 1.03, 95% CI 1.01-1.05, P = 0.003). At greater risk of SVPT were: young adults (<21 versus ≥21: risk ratio 3.05, 95% CI 1.31-7.06, P = 0.01), White British people (versus Pakistani people: risk ratio 2.24, 95% CI 1.25-4.02, P = 0.007) and those with criminal convictions (risk ratio 2.23, 95% CI 1.01-4.95, P = 0.048). No associations were found with life events, social assets and political engagement. CONCLUSION: Depression, dysthymia and symptoms of anxiety and post-traumatic stress are associated with extremist sympathies.

"Who needs secure services for personality disorder?" Results of an expert Delphi study with professional staff.

BACKGROUND: Personality Disorder (PD) is an enduring, multi-faceted mental disorder, associated with adverse health effects, difficulties with interpersonal relationships and in some cases increased risk to others. A limited number of dedicated forensic mental health services are available for serious offenders with severe personality disorder. The recent Offender Personality Disorder (OPD) strategy aims to ensure that most such offenders are treated in prison rather than secure psychiatric services, except in highly complex cases where this is not possible. While the strategy sets out very broad criteria relating to this, greater clarity is needed to support decisions about appropriate transfer and hence enhance public protection. This study explored which characteristics professional experts associate with appropriate transfer from prison to forensic mental health services for high-risk offenders with PD. METHOD: A modified Delphi survey distributed through an online survey system was conducted in two-rounds with a group of professional experts recruited from forensic mental healthcare; criminal justice and specialist commissioning. RESULTS: Fifty-one (56%) respondents completed stage one of the Delphi and 34 (61%) of these completed stage two. Consensus was reached for a total of 22 items indicating complexity, including co-morbid mental illness, high level of risk, lack of progress in prison and high motivation for treatment. A preliminary checklist for these factors was developed. Panel members consistently emphasised the importance of the individual's presenting need, the overall clinical picture and formulation in their free text responses. CONCLUSIONS: Professionals face a complex picture when making decisions regarding suitability for hospital admission for high-risk male offenders with PD, with varied opinions amongst professional experts as to priorities for intervention and a focus on individual needs through formulation. It was, nevertheless, possible to condense these views into a set of consistent variables that can be used to highlight the need for transfer into hospital-based treatment services.

Does "Enhanced Support" for Offenders Effectively Reduce Custodial Violence and Disruption? An Evaluation of the Enhanced Support Service Pilot.

This study aimed to examine the effectiveness of The Enhanced Support Service (ESS) pilot in reducing custodial violence and disruption, and the associated costs, by observing the behavioural change of the 35 service users who participated in ESS intervention within its first 22 months of operation. Frequencies of recorded incidents of aggressive behaviours, self-harming behaviours, noncompliance, and positive behaviours were counted from routine administrative systems using a coding structure developed in previous studies. The count data were analysed using nonparametric tests and Poisson regression models to derive an Incident Rate Ratio (IRR). Findings suggest the ESS is associated with a reduction in aggressive behaviours and noncompliance, with medium to large effect sizes ( r = .31-.53); however, it was not associated with a reduction in deliberate self-harm or increased positive behaviours. The Poisson models revealed that levels of pre-intervention behaviour, intervention length, intervention completion, and service location had varying effects on postintervention behaviour, with those who completed intervention demonstrating more favourable outcomes. The ESS service model was associated with a reduction in behaviour that challenges, which has implications for the reduction in associated social, economic, and political costs-as well as the commissioning of interventions and future research in this area.

Triage, decision-making and follow-up of patients referred to a UK forensic service: validation of the DUNDRUM toolkit.

BACKGROUND: Forensic medium secure services in the UK are a scarce but essential resource providing care for those in the criminal justice system with severe mental disorder. Appropriate allocation of beds to those most in need is essential to ensure efficient use of this resource. To improve decision-making processes in a UK forensic service, an admissions panel utilized the DUNDRUM 1&2 (D1 & D2) triage instruments. METHODS: Demographic, diagnostic and clinical information on a prospective sample of referrals to a UK adult forensic service was gathered (n = 195). D1 and D2 measures were scored by a panel of clinical managers considering referral information and clinician opinion in reaching their ratings; those not admitted were also followed up. RESULTS: Within the sample, D1 ratings were predictive of decisions to admit (AUC = .79) and also differentiated between levels of security (F(4) = 16.54, p < .001). Non-admission was not significantly associated with increased risk of offending at follow-up. Items relating to self-harm and institutional behaviour did not show a predictive relationship with the panel decision to admit. CONCLUSIONS: Use of a structured professional judgement tool showing good predictive validity has improved transparency of decisions and appears to be associated with more efficient use of resources, without increased risk to the public.

The Impact on Staff of Working with Personality Disordered Offenders: A Systematic Review.

BACKGROUND: Personality disordered offenders (PDOs) are generally considered difficult to manage and to have a negative impact on staff working with them. AIMS: This study aimed to provide an overview of studies examining the impact on staff of working with PDOs, identify impact areas associated with working with PDOs, identify gaps in existing research,and direct future research efforts. METHODS: The authors conducted a systematic review of the English-language literature from 1964-2014 across 20 databases in the medical and social sciences. RESULTS: 27 papers were included in the review. Studies identified negative impacts upon staff including: negative attitudes, burnout, stress, negative counter-transferential experiences; two studies found positive impacts of job excitement and satisfaction, and the evidence related to perceived risk of violence from PDOs was equivocal. Studies demonstrated considerable heterogeneity and meta-analysis was not possible. The overall level of identified evidence was low: 23 studies (85%) were descriptive only, and only one adequately powered cohort study was found. CONCLUSIONS: The review identified a significant amount of descriptive literature, but only one cohort study and no trials or previous systematic reviews of literatures. Clinicians and managers working with PDOs should be aware of the potential impacts identified, but there is an urgent need for further research focusing on the robust evaluation of interventions to minimise harm to staff working with offenders who suffer from personality disorder.

Psychiatric diagnosis and differential risks of offending following discharge.

Psychiatric diagnosis is not considered a risk factor for offending following discharge. However, treatment interventions and aftercare are strongly influenced by clinical primary diagnosis. We compared differential risks of reoffending of patients falling into six primary diagnostic categories following discharge from Medium Secure Units in the UK: schizophrenia/schizoaffective disorder; delusional disorder; mania/hypomania; depressive disorder; organic brain syndrome; personality disorder. We followed up 1344 patients, on average 6.2 years (SD=2.1) at risk, discharged from 7 of 14 Regional Medium Secure services in England and Wales. Outcomes were period prevalence, incidence, and cumulative probability of criminal conviction. Established demographic and criminal history predictors of reoffending were observed across different diagnostic categories. Risks of all offending were increased for personality disorder, violence/acquisitive offending for delusional disorder, sexual offending for mania/hypomania and violence/acquisitive offending for organic brain syndrome. Patterns of risk over time differed markedly between categories of mental disorder. Most patients with personality disorder who offended violently did so within 4 years of discharge. A subgroup with delusional disorder demonstrated increased risk of violent offending 5 years after discharge. Differential risks of reoffending are observed between different diagnostic groups. Clinical diagnosis should be included together with established risk measures in risk management following discharge. Close supervision of patients with personality disorder should begin immediately after discharge when risks of reoffending are greatest. For delusional disorder further investigation is needed into the marked increase in risk of violence after 5 years.

Factor structure of the Essen Climate Evaluation Schema measure of social climate in a UK medium-security setting.

BACKGROUND: Social climate has an influence on a number of treatment-related factors, including service users' behaviour, staff morale and treatment outcomes. Reliable assessment of social climate is, therefore, beneficial within forensic mental health settings. The Essen Climate Evaluation Schema (EssenCES) has been validated in forensic mental health services in the UK and Germany. Preliminary normative data have been produced for UK high-security national health services and German medium-security and high-security services. AIMS: We aim to validate the use of the EssenCES scale (English version) and provide preliminary normative data in UK medium-security hospital settings. METHODS: The EssenCES scale was completed in a medium-security mental health service as part of a service-wide audit. A total of 89 patients and 112 staff completed the EssenCES. RESULTS: The three-factor structure of the EssenCES and its internal construct validity were maintained within the sample. Scores from this medium-security hospital sample were significantly higher than those from earlier high-security hospital data, with three exceptions--'patient cohesion' according to the patients and 'therapeutic hold' according to staff and patients. CONCLUSION: Our data support the use of the EssenCES scale as a valid measure for assessing social climate within medium-security hospital settings. Significant differences between the means of high-security and medium-security service samples imply that degree of security is a relevant factor affecting the ward climate and that in monitoring quality of secure services, it is likely to be important to apply different scores to reflect standards.

Adult antisocial syndrome co-morbid with borderline personality disorder is associated with severe conduct disorder, substance dependence and violent antisociality.

This study tested the hypothesis that syndromal adult antisocial behaviour (AABS) co-morbid with borderline personality disorder (BPD) is a syndrome that emerges from severe conduct disorder (CD) in childhood and adolescence and is strongly associated, in adulthood, with both violence and substance dependence. In a sample of 8 580 community-resident adults screened for the presence of personality disorders, the following predictions arising from this hypothesis were tested: first, that those with AABS co-morbid with BPD would, in comparison with those showing AABS or BPD only, show a high level of antisocial outcomes, including violence; second, that adjusting for co-morbid alcohol dependence would attenuate group differences in many of the antisocial outcomes, and violence in particular; and third, that the AABS/BPD group would show both a high prevalence and a high severity of CD, and that adjusting for co-morbid CD would attenuate any association found between AABS/BPD co-morbidity and violence. Results confirmed these predictions, suggesting that AABS/BPD co-morbidity mediates the relationship between childhood CD and a predisposition to adult violence. The triad of AABS/BPD co-morbidity, alcohol dependence and severe CD is likely associated with the risk of criminal recidivism in offenders with personality disorder following release into the community.

An evaluation of case formulation training and consultation with probation officers.

BACKGROUND: Formulation is a core competency of mental health professionals, drawing on a variety of sources of information. In England and Wales, the current strategy for offenders with personality disorder places formulation-led management, generally by probation staff, at its core, but reliability and validity of the process remain unclear. AIMS: The first aim was to evaluate a checklist previously designed to establish quality of formulation, and the second to measure the impact of training and consultation on the ability of probation officers to formulate cases. METHODS: The inter-rater reliability, test-re-test reliability and internal consistency of the McMurran formulation checklist were calculated from the scores derived from randomised formulations completed by probation officers from fictitious case vignettes. The impact of training was measured by comparing pre- and post-training formulations of these vignettes. Practice cases formulated by probation officers at psychologist-facilitated consultation meetings over a 6-month period were used to measure the impact of consultation. All formulations were scored blind by independent experts. RESULTS: Inter-rater reliability, test-re-test reliability and internal consistency of the scale were all acceptable. Training and practice did not significantly improve the probation officers' formulations. CONCLUSIONS: The purpose and utility of formulation may vary according to the context in which it is applied. Progress in developing formulation skills may depend on the nature and length of the previous experience of this skill. Future research should take account of such variance, with this scale as a potentially useful aid in monitoring progress. IMPLICATIONS: The capacity for teaching formulation to probation officers could be investigated further by comparing the process with formulation development by mental health experts with previously extensive formulation experience. Formulation will probably need to be adapted to meet the needs of the context in which it is developed. The relationship between formulation and management outcome was not investigated here and would be a further important step.

The clinical profile of high-risk mentally disordered offenders.

PURPOSE: High-risk mentally disordered offenders present a diverse array of clinical characteristics. To contain and effectively treat this heterogeneous population requires a full understanding of the group's clinical profile. This study aimed to identify and validate clusters of clinically coherent profiles within one high-risk mentally disordered population in the UK. METHODS: Latent class analysis (a statistical technique to identify clustering of variance from a set of categorical variables) was applied to 174 cases using clinical diagnostic information to identify the most parsimonious model of best fit. Validity analyses were performed. RESULTS: Three identified classes were a 'delinquent' group (n = 119) characterised by poor educational history, strong criminal careers and high recidivism risk; a 'primary psychopathy' group (n = 38) characterised by good educational profiles and homicide offences and an 'expressive psychopathy' group (n = 17) presenting the lowest risk and characterised by more special educational needs and sexual offences. CONCLUSIONS: Individuals classed as high-risk mentally disordered offenders can be loosely segregated into three discrete subtypes: 'delinquent', 'psychopathic' or 'expressive psychopathic', respectively. These groups represent different levels of risk to society and reflect differing treatment needs.
